What are the fruits suitable for growing in the south?

The temperature in the south is suitable, which is very suitable for growing fruits. So what kind of fruit should be planted in the south? The following are the fruits that I have carefully arranged for you, which are suitable for growing in the south. Let's have a look.

Fruits suitable for growing in the south.

banana

Bananas like hot and humid climate, and grow vigorously on the land with deep soil layer, loose soil and good drainage. Irrigation planting is also successful in semi-arid areas such as southern Jamaica. Wild bananas are cultivated by seeds, and artificial bananas can be cultivated by root sucking and pseudobulb ramets. The first harvest takes 10 ~ 15 months, and then the harvest is almost continuous.

grape

The annual average temperature is above 20℃, which is most suitable for growing in areas without severe frost and freezing injury in winter. In winter, it can tolerate a short-term low temperature of MINUS 3℃, but when the temperature drops below 4℃, serious freezing damage will occur. Areas with rainfall of 1200 ~ 1400 mm can grow normally and have wide adaptability to soil. They can be cultivated along rivers, hills, mountains, red yellow soil and gravel soil, and can grow well as long as the soil layer is deep and the drainage is good.

peach

Peach is a small deciduous tree of Prunus in Rosaceae, which is planted all over the world. Flowers are ornamental, fruits are juicy, and can be eaten raw, pickled or canned, and nucleolus can also be eaten. The flesh is white and yellow, and there are many varieties of peaches. Generally, the skin is hairy. Nectarine skin is smooth. Flat peach? The fruit is flat and disc-shaped. Peach? This is an ornamental peach tree with various forms of petals.

pear

Pear is a perennial deciduous tree fruit tree of Rosaceae, which is distributed in North China, Northeast China, Northwest China and the Yangtze River valley provinces. There are many kinds and varieties, and the adaptability to the external environment is stronger than that of apples. Cold tolerance, drought tolerance, waterlogging tolerance and salt tolerance. In areas where the lowest temperature in winter is above -25 degrees, most varieties can survive the winter safely.

Fruits suitable for southern summer planting.

1, banana

Do you have any bananas? The crown of fruit? Good name, mainly produced in southern China. Bananas contain a variety of nutrients, but they are low in sodium and free of cholesterol. After eating, they can provide various nutrients to the human body without making people fat. Eating bananas regularly is not only beneficial to the brain, preventing nerve fatigue, but also has the functions of moistening the lungs, relieving cough and preventing constipation.

2. mangosteen

In the tropics, there are abundant fresh fruits all year round, but they are called? Fruit queen? Mangosteen is produced only once every six months. People call it? After fruit? And then what? The fruit of God? . Mangosteen is cold, has antipyretic and cooling effects, and can dissolve fat, moisten skin and reduce fire. If the skin is sore and young people get acne, you can eat mangosteen raw or make soup.

3. Myrica rubra

Myrica rubra is a famous specialty fruit in southern China, mainly produced in the south of the Yangtze River. It is cultivated most in Zhejiang. Myrica rubra fruit ripens in early summer, is sweet and sour, and has a unique flavor. According to "Qunfangpu"? Yangmei, will the producer be the best in the world? , whenever? Is Myrica rubra full of mountain red in summer solstice? In the new season, tourists from all over the world flock to taste this traditional fruit.

4. carambola

What is a warm southern city in summer? Where's Yang? The tree is covered with five-pod, the color is green and yellow, and the skin is as thin as film. Just looking at it makes people happy. Carambola contains a variety of ingredients beneficial to human health, such as sugar, vitamin A, vitamin C, various fibers and acids, and has a good effect on treating aphtha, chronic headache, traumatic injury, swelling and pain.

5, yellow skin

Wampee is one of the fruits in southern China, which is rich in sugar, organic acids, pectin, vitamin C, volatile oil, flavonoid glycosides and so on. Huangpi has the effects of eliminating fullness in chest and abdomen, promoting fluid production to quench thirst, regulating qi and relieving cough; Bitter yellow skin has a particularly good effect. The bitter taste of wampee can stimulate bile secretion, promote digestion and make absorption function vigorous.

6.mango

Fresh mangoes are native to the tropics. Mango has the effects of relieving cough and asthma, and has the function of assisting diet therapy for cough, excessive phlegm and asthma. Mango contains mangnolic acid and other compounds, which have anticancer pharmacological effects. Mango juice can increase gastrointestinal peristalsis and shorten the retention time of feces in colon, so it is very beneficial to prevent and treat colon cancer.

7.papaya

Papaya is a tropical fruit, and there are many in the south. Papaya is more common. White King? Known as. Papain in papaya can help human body decompose meat protein. Eating a small amount of papaya after meals has a certain effect on preventing gastric ulcer, gastroenteritis and indigestion.

8. Coconut

Coconut is a tropical light-loving crop, which grows well in high temperature, rainy, sunny and sea breeze. Coconut is sweet and flat, and enters the stomach, spleen and large intestine; The pulp has the effects of tonifying deficiency, strengthening body resistance, invigorating qi, expelling pathogenic wind, eliminating malnutrition and killing insects. Long-term consumption can moisten the face, benefit people's vitality and resist hunger. Coconut water has the effects of nourishing, clearing away heat and relieving summer heat and quenching thirst, and is mainly used for thirst caused by summer heat and body fluid deficiency.

9, jackfruit

Jackfruit is native to India and is widely cultivated in tropical and humid areas. It is recorded in Compendium of Materia Medica:? Jackfruit is sweet and fragrant, which can quench thirst, relieve annoyance, invigorate spleen and qi. ? Because jackfruit contains carbohydrates, sugar, protein, starch, vitamins, amino acids, calcium, iron and potassium, and contains a certain amount of plant fat and various minerals beneficial to human body, it not only has high medicinal value, but also has the functions of strengthening body and prolonging life, and is a natural health-care fruit.

10, litchi

Has the effects of promoting fluid production, quenching thirst, invigorating spleen and regulating stomach. Used for deficiency of stomach yin, vexation and thirst, and deficiency of spleen and stomach. Eating it in summer can invigorate qi, nourish blood, recharge your batteries, and can also be used to treat anemia, postpartum weakness, insomnia, amnesia, and lack of body fluid.

Banana planting method

First, preparation and colonization before planting

1. Cultivated land and planning

The newly reclaimed shrub wasteland should be cleared by bulldozer first, and then ploughed, and the ploughing depth should be greater than 40cm. Clean up the branches and roots, and then plow and rake with a rubber machine. Rubber wheel plows and rakes can be used in paddy fields or other cultivated land. After ploughing and harrowing, overall planning should be carried out according to the terrain. Generally, about 30 mu is a unit area, and there should be roads on four or three sides of the unit area to facilitate banana harvesting in the future. The main road is 6 meters wide (including road ditch) and the branch road is 4 meters wide (including road ditch). At the same time of road planning and unit division, the layout of main water supply pipes and the preset packaging plant should be considered as a whole. When conditions permit, general water pipes should be laid on the roadside to facilitate maintenance.

2. Preparation of base fertilizer

In order to facilitate fertilization nearby, it is suggested that the amount of organic fertilizer required per unit area should be calculated first, and the organic fertilizer and phosphate fertilizer should be mixed evenly and stacked in the unit area. The organic fertilizer can be farmyard manure, chicken manure, bean cake, etc. The amount of organic fertilizer should be determined according to soil fertility and the type of organic fertilizer used. It is generally recommended to use more organic fertilizer than chemical fertilizer. The phosphate fertilizer of compost can be calcium superphosphate, and the required fertilizer amount is calculated according to 3~4 liang per plant. Phosphate fertilizer should be crushed and sieved, mixed with the required organic fertilizer, tightly covered with film and stacked for more than one month, and can be used only after it is fully decomposed.

3. Hangxinggou

As far as possible, ditch in the unit area according to the horizontal line, and it is better to plant in wide and narrow rows. The row spacing is 2.8m, the row width is1.5m, the plant spacing is1.8 ~ 2m (the plant spacing can be adjusted according to the needs of varieties), and 155~ 172 plants are planted per mu. Wide and narrow row planting mode is beneficial to ventilation, light transmission and management operation of bananas, especially for large and medium-sized bases with agricultural machinery.

4. Drainage ditch excavation

Bananas love water and are afraid of water, so drainage ditch excavation should be planned before planting. Whether it is sloping land or paddy field, drainage ditches should be dug in low-lying areas according to the terrain to improve the drainage system inside and outside the unit area. If it is a plot with high groundwater level, it is necessary to alternate wide and deep ditches to reduce the groundwater level. A perfect drainage system can avoid heavy rain and soil erosion.

5. Dig a hole and apply base fertilizer

According to the planting specifications, dig a pit along the low potential surface of the drainage ditch, and the pit size is 60X60X50cm. Two rows of narrow rows adopt staggered excavation holes, which are triangular. Narrow row 1.5 m wide row 2.5? 2.8m narrow line1.5m.

Generally, manual excavation is needed, because the soil in the hole is often scattered in the process of mechanical excavation, which is not easy to return to the soil, and it is labor-consuming and time-consuming, which is not suitable. Then, apply farmyard manure, 2-4 kg per hole, add 20-30 grams of Lianling or Mi Le II or Shennongdan to control underground pests, backfill the topsoil of half holes and mix well, paying special attention to mixing well, otherwise there will be root burning in the future. And then back to Tu Ping Cave.

6. Laying water pipes and sprinkler irrigation belts

If flood irrigation is adopted, water pipes should be laid to the highest point of unit area, and irrigation ditches should be dug according to the terrain after boiling water to ensure that water can reach any part of unit area. But flooding irrigation is the most backward irrigation method in banana planting. Unless there is gravity irrigation with water conservancy system, sprinkler irrigation should be advocated. Sprinkler irrigation is a more economical and effective way to use power pumping irrigation. Use PVC75? Pipes are installed in the vertical direction from the middle of the ground unit to the block unit. The specific pipeline installation method should be determined according to the terrain, but the length of each sprinkler belt should not exceed 80 meters. The sprinkler irrigation belt adopts double spray belts, which are laid in the middle of narrow rows and vertically connected with 75? Tube.

7. Chemical weeding in banana plantations

Speaking of which, some people may wonder, weed before planting bananas? In fact, chemical weeding is necessary this time, because there is a period of time between the completion of mechanical tillage and sowing. In the three months after planting, farmers have more work to do and no time for manual weeding. Banana seedlings are too small to be chemically weeded. In addition, after planting, irrigation or rain makes the banana garden wet and easy to grow grass, so weeding before planting is very important. If grass grows in the field, it can be sprayed all over the garden. If there is no grass in the field, you can spray herbicides, such as acetochlor, before germination.

⒏ Selection and classification of seedlings

The seedlings cultivated in the nursery can be planted in 4~8 pieces. Nowadays, it is advocated to cultivate big seedlings in big bags, especially when the old banana garden can't get enough soil preparation and rotation after harvesting bananas, changing big bags in the nursery can grab the season in a certain period of time. Banana plantlets should be selected and graded before they leave the nursery. First, the mutant plants should be eliminated, and then the healthy banana seedlings should be divided into three grades according to their size, and the same grade should be planted in the same unit. In this way, in the future management process, the banana seedlings in the unit grow more consistently, the growth period is synchronized, the harvesting time is concentrated, and the harvesting process is shortened.

Pet-name ruby colonization

Bananas can be planted in Hainan all year round. Choosing the right planting time is an important link for the success of banana production. The specific planting time should be determined according to the geographical location, planting purpose and market demand of banana plantation. But it's best to avoid the typhoon season, or take some risks to avoid it. In Hainan, typhoons are mainly concentrated in July and August, but rarely in June and September. So it is best to sow in April-June, and harvest better in February-May next year. Water should be poured on the unit area the day before planting to make the soil moist. When planting, dig a hoe about 20cm deep on the surface of the pit that has been returned to the soil, hold the nutrient soil of banana seedlings in your right hand, gently hold the bottom of the nutrient cup (bag) for seedling raising with your left hand, take it out (be careful not to scatter the nutrient soil), put the nutrient soil into the pit that has just been dug, return the soil, and press it with your hands. The planting depth should not be too deep, but 2~3cm beyond the nutrient soil. It is best to choose cloudy or sunny afternoons for planting. After planting, water a row of root water to ensure the survival rate of banana seedlings. For individual wilting plants, leafy branches can be inserted around the seedlings for shade to improve their survival rate.

Second, early management.

Early management generally refers to the management from planting to flower bud differentiation (about 75 days after planting). Early management should pay attention to maintaining full seedlings (that is, no shortage of plants), full seedlings (that is, the law of growth period) and re-fertilization during flower bud differentiation. Due to the influence of water and fertilizer conditions or natural factors, the flower bud differentiation period may be advanced or postponed. How to judge the growth of banana in flower bud differentiation stage? It is generally believed that when 3~5% plants in a unit area have bud absorption, it can be considered that bananas in that unit area have entered the stage of flower bud differentiation. The main pests in the early stage are Spodoptera litura, aphid and red spider, which can be controlled according to the pest control method in Chapter 4. The main diseases are mosaic disease, root-knot nematode disease and physiological diseases (such as head rot, fertilizer damage and root burning disease). ). If plants with mosaic heart rot are found, they should be dug up in time, and if necessary, big bag seedlings or big healthy buds can be replanted in the old banana garden. However, it should be noted that after the diseased plants are dug out, the original acupoints must be disinfected with lime for two days before replanting.

1. patrol seedlings

The first inspection of seedlings was the day after planting. If missing seeds are found, they should be replanted in time. After watering, the skewed plants should be righted and compacted, and the plants exposed from the soil surface should be compacted. If the planting is too shallow, they can replant. Patrol every 10 day or after heavy rain. During the inspection, it is found that the banana seedlings buried by rain should be cleaned up or replanted in time, the flooded holes or ditches must be drained, and deep ditches should be dug for drainage where the drainage is not smooth. The washed ditch should be repaired, and sandbags should be added to block the ditch if necessary to avoid serious soil erosion. The most important purpose of checking banana plantations is to find pests and diseases and whether there are weak seedlings early. If dead seedlings are found in the management process, they must be replanted in time, and weak seedlings can be replanted at intervals of about 20cm to ensure that the seedlings are in full bloom.

4. Water and fertilizer management

Within 7 days after planting, it belongs to the slow seedling stage and does not need fertilization. The main job is to water and keep the soil moist; Dredge ditches to ensure good drainage after rain; Level the periphery of the plant and trim a disk with a radius of about 30cm for future watering and fertilization. Within 7 to 30 days, water and fertilizer are poured every 3 days, and 0.3~0.5% (concentration gradually increases) urea water or other liquid fertilizer (depending on the concentration of liquid fertilizer) is applied. The method is to wet the soil layer with a small amount of water in the whole garden, pour the water and fertilizer into the plate, and mix the fertilizer with 2kg per plant. Be careful not to pour it too fast, so as not to pour it into the leaves of banana seedlings, and water can't penetrate from the disc. If the soil is hard, loosen the soil in the fruit bowl before watering it. From 1 month to flower bud differentiation stage, fertilization can be carried out according to the fertilization schedule to keep the soil moist without water accumulation. It is important to mark the slightly weak seedlings found during the inspection. For such seedlings, it is necessary to water frequently and apply more fertilizer, and 0.3% calcium nitrate or high-quality fertilizer and amino acid liquid fertilizer can be applied once every other day. This work, commonly known as seedling adjustment in production, aims to make the growth period of banana seedlings per unit area basically the same.

3. intertillage weeding

At this stage, banana plantations should be kept free of grass. Narrow grass can be weeded by manual weeding combined with loosening soil, and wide grass can be weeded by mechanical weeding combined with intertillage. For heavy fertilizer applied during flower bud differentiation, machinery or cattle can be used to ditch 60cm away from the plant, put the fertilizer into the ditch, and then cover the soil with a small rake to trim or ridge the platform. Generally, platforms are better for dry slopes, and paddy fields can be ridged to facilitate drainage in rainy season.

Third, medium-term management

Mid-term management generally refers to the management from flower bud differentiation stage to germination stage. Mid-term management is mainly based on pruning platforms or ridging, topdressing and attacking buds. In terms of pests and diseases, it is necessary to focus on preventing banana leaf spot and preserving functional leaves as much as possible, which is also the key to high quality and high yield of bananas. At the same time, sporadic mosaic heart rot or mutant plants should be dug up as soon as possible, and no more seedlings should be replanted. Insect pests mainly include red spider, crown net stinkbug and banana weevil.

1. Repair the platform or raise the soil.

After the application of heavy fertilizer in flower bud differentiation stage is completed, the platform should be trimmed or ridged according to the terrain to store water and protect fertilizer. This is a heavy job, so we should increase temporary work and try our best to finish it in a short time. The leveling of the platform or the trimming of the ridge will directly affect the water and fertilizer management in the future.

4. Water and fertilizer management

After applying heavy fertilizer in the flower bud differentiation stage, water should be poured once to ensure that the soil layer above 40cm depth is soaked, and then the banana garden should be kept moist without water, and fertilization should be carried out 20 days later. According to the growth situation of banana (the growth speed of leaves and the length of internodes), on the basis of banana fertilization scheme table, some adjustments were made for future fertilization. Buding fertilizer is generally controlled about fifteen days before budding, and the application period of sprouting fertilizer can be judged according to the calculation of banana growth period or the obvious thickening of banana pseudostem base.

3. Chemical weeding.

Weeding has been done when the platform is trimmed or ridged, and the weeds in the banana garden are relatively clean. If weeds grow again in future production management, chemical agents can be used to weed. It is best to use Gramoxone or Baccarat for weeding in banana orchards, and glyphosate or Roundup is strictly prohibited.

4. Bud removal technology in banana orchard.

From the flower bud differentiation stage, the mother plant of banana will grow sucking buds one after another. With the growth and increase of these sucking buds, a lot of nutrients will be consumed by the mother plant. Therefore, it is necessary to cut off the sucking buds in the banana orchard and destroy their growing points, otherwise the cut sucking buds will sprout again. The usual practice is to cut off the sucking buds and drop kerosene to kill the growing points of the sucking buds, which should be determined through field experiments.

Fourth, post-management

Post-management refers to the management from budding to harvest. Post-management is complex and important, which directly affects the quality of bananas, so post-management is also called banana quality management. Pests mainly control banana flower thrips, with emphasis on scab. At the same time, control should be carried out according to the occurrence of red spider, aphid and leaf spot.

1. Xiao Lei

When the banana bud is just pulled out, it may just hang on a leaf. When the bud axis continues to lengthen and the center of gravity moves outward, it will instantly crush the leaves, and the bud will suddenly sag and break the fruit axis. Therefore, the buds must be calibrated before the leaves are crushed. The method is: gently lift the bud with Mu Cha, slowly transfer to the gap between two leaves, and slowly hang the bud. Be careful not to push too hard in this work, or grapefruit may break its bud during operation. In addition, in the budding stage, bananas will also drop buds because of good fertilizer and water conditions, excessive growth and rainy weather.

Trim leaves

When the buds droop and continue to elongate, tear off the leaves that may touch the banana fruit. If the petiole is close to the banana fruit, in order to prevent the banana fruit from being damaged by the wind, the banana bud can only be gently folded away from the base of the petiole outward and downward. The only serious effect is to cut the leaves from the petiole. In field work, leaves are also tied to the side. Practice has proved that tying leaves will often cause the tied leaves to dry up, so it is better to fold them and save them.

Thin the fruit.

When producing 4-5 combs, bananas must be thinned. If the fruit fingers of each banana comb are larger than 24 (winter bananas) or 26 (spring and summer bananas), the redundant fruit fingers must be removed: one on each side of the fruit comb and one every 3-4 fruit fingers. The principle is that only one finger can be thinned at the same position, and the upper and lower rows cannot be aligned to thin the fruit, otherwise a large gap will be left on the banana comb, and the comb will be easily broken during harvesting and packaging. After thinning, the banana fruit index of the head comb is less than 10, and the banana fruit index of the tail comb is less than 14, which must be removed by combing. Fruit thinning must be timely, banana fingers are tender and easy to break, no,

Other fingers are injured, and the residual gap is small.

Step 4: Leave the comb and break the bud.

Generally, bananas can draw 5- 10 combs, and the number of combs left in bananas can be determined according to the size of the tree, the number of functional leaves and the thickness of the fruit shaft. Under normal circumstances, it is advisable to leave more than 6 combs for bananas in winter and 7 combs for bananas in spring and summer. In the process of leaving combs, if the number of fruit combs is large, you can consider removing the head comb. After leaving enough combs, leave a single fruit in the next comb, and break the bud at the position of 10cm below the axis of single fruit. Leave enough hair combs, and break the buds as soon as possible after single fruit, so as to avoid the elongation of the buds consuming the nutrients of banana trees.

Painting flower

When thinning fruits and leaving combs, we should combine painting. The best time to smear flowers is when the fingers are not fully unfolded and the petals are easy to fall off when touched by hand, so that the banana fingers are close, the petals are easy to fall off, the style is brittle, the efficiency of smear flowers is high, the fingers are not damaged, and banana milk does not pollute banana fruits. Some people think that it is best to paint the banana fruit when it is flat and slightly curved, which will damage the fruit prematurely and the fruit index will not be long; Some people don't even advocate painting flowers. However, field practice has proved that whether to smear flowers or not, whether to smear flowers sooner or later, has no obvious effect on the growth and fruit index length of bananas, but to produce high-quality bananas, it is necessary to smear flowers. Don't wear gloves when wiping flowers. The wiping of a banana fruit string should be carried out twice or more, that is, the first 2~3 combs should be wiped when the fruit is thinned, and the remaining banana flowers should be wiped when the comb is broken.

6. Bag-making materials

Spray bananas as soon as possible after brushing and combing. When the liquid medicine is dry, it can be bagged. Bagging, fruit sorting, comb bagging and fruit string bagging. Fruit comb bagging means that the end of each combed fruit is covered with a white film bag with small holes except the head comb to avoid friction between the end of the fruit comb and the banana combed on the back. The fruit bunching bag is to cover a layer of perforated pearl cotton on the banana bunches, and tie the top tightly on the fruit shaft with a straw rope. Then, two newspapers are tied outside the pearl cotton bag to block the southwest direction and the position where the banana bunches are easy to bask in, so as to prevent the sun from basking at the ends of the fruit fingers, and a perforated blue plastic film bag is covered on the outer layer. Bagging can keep cold, make banana fruits well colored, reduce pests and diseases, and avoid trauma. Requirements for tying position: the higher the bag, the better it can cover the whole fruit string, if conditions permit. At least 30cm away from the fruit axis of banana.

7. Marking and fruit lanyards

After bagging, tie a straw ball rope at the end of the fruit string to mark the different growth stages of the banana string. For banana bunches that are not perpendicular to the horizontal plane, in order to avoid diagonal combing, loose combing and irregular fruit combing, the fruit bunches are pulled against the banana trees to make them perpendicular to the horizontal plane. The color of straw rope should be changed once a week, and the number of bagged plants should be registered. According to the color of the rope, the harvest period can be counted, estimated and harvested.

8. Support bananas with poles

In Hainan, bananas harvested from May 438+0 to March 6, only bananas with an inclination of more than 15 degrees were supported by poles; Bananas harvested from April to July, bananas with slightly inclined banana trees or heavy fruit clusters must be supported by vertical poles; Bananas harvested in August-165438+ 10 must be supported by vertical poles, and the vertical poles must be completed before the typhoon season. Generally, the vertical pole is 20cm away from the banana head and the hole is 40cm deep. Press the wooden pole into the hole, and then tie the banana pseudostem to the wooden pole. After budding, the upright post should avoid the contact between the wooden pole and the banana fruit, causing fruit damage.

Pet-name ruby fertilizer and water management

After bagging, 2-2 pieces of compound fertilizer can be applied to promote fruit growth, and the application method is spraying after irrigation. In addition, banana fruit refers to the period when young fruit grows faster when it is combed backward, so liquid fertilizer must be sprayed on banana fruit, and the concentration should not be too high, otherwise it will cause phytotoxicity to young fruit. Banana evergreen and potassium dihydrogen phosphate can be used, and fine droplets can be sprayed evenly from bottom to top. It is better if there are droplets that do not merge. The fruit surface fertilizer can be used simultaneously with pest control, that is, sprayed once after the first application and before bagging, and can be mixed with thiophanate-methyl suspension, imidacloprid, banana evergreen and potassium dihydrogen phosphate.
