Planting method and time of green vegetables

1. Small vegetable planting knowledge (small vegetable planting technology in summer)

Knowledge of planting small vegetables (planting techniques of small vegetables in summer) 1. Planting techniques of small vegetables in summer

3000 kg of high-quality decomposed organic fertilizer and 15% bio-organic fertilizer as base fertilizer; After fertilization, turn the soil to a depth of about 1.5 cm, dry it in the sun for 23 days, furrow it according to the width of 2 meters and the height of 5 cm, break the clods, level the furrow surface, and match the internal and external furrows, and use seeds of 1.5 kg per mu. After sowing, mix the seeds with a small amount of dry fine soil and spread them evenly with small nails.

Water 1~2 times a day on sunny days to keep the soil moist. The watering time should be determined according to the sky, ground and water. Generally, it should be watered in the morning and evening, the earlier the better, and at night 19 ~ 20.

The watering method is generally sprayed directly on the insect-proof net and patted the topsoil with a shovel. In case of dry weather, you need to roll the soil with your feet or stones, and finally pour water on your feet. Generally, seedlings can emerge after 3 days. Third, prevention and control of diseases, pests and weeds In order to prevent and control diseases, each kind of two-crop small vegetables is disinfected once, and Heng Lv 1 solution is sprayed 5000 times each time; In order to prevent grass damage, 48% trifluralin EC herbicide was sprayed after sowing and before emergence. In order to prevent the harm of flea beetle, spray it once after sowing or before 2 leaves.

In the future, if a small number of pests are found, BT or Cai Xi, Lv Jing and other pesticides with high efficiency, low toxicity and low residue should be sprayed. Stop taking medicine for l5 days before harvest.

Fourth, pull the net to cover the shed. Generally, after sowing and spraying, insect-proof nets should be pulled. It must be sealed at the second leaf stage at the latest, and both sides should be compacted with bricks. In hot and dry weather, insect-proof nets can be laid flat on the border after sowing, which can keep moisture and promote seedling emergence.

After eclosion, the insect net is propped up with a bamboo bow. Let the water pour down from the upper part of the insect net, one by one, without going back to replenish water, and the amount of water per mu is 4000~5000 kg.

Six, stubble frequency and yield ● Planting small vegetables with insect-proof nets in summer can effectively prevent insects, which not only ensures that small vegetables are pollution-free. Moreover, the growth period is advanced by about 6 days, the yield is increased by more than 30%, the appearance is fresh and tender, the color is bright and the quality is good.

Generally, the yield per crop is about 20 days 1500 kg. Six crops of small vegetables can be continuously planted in one field, and it can be baked intermittently for 7- 10 days before sowing, which makes the soil dry and loose and plays a bactericidal role.

2. How to grow small vegetables

One characteristic: Xiaoqing (white) cabbage is relatively cold-resistant, belonging to direct root system, with shallow root distribution, soft leaves, large evaporation and high requirements for soil humidity and air humidity; The short growth period requires loose and fertile loam or sandy loam with convenient irrigation and drainage, which requires more nitrogen, followed by potassium and less phosphorus.

Second, choose Xiaoqing (white) vegetable varieties suitable for local cultivation.

3. Soil moisture leveling: after harvesting, turn the kang deeply, apply foot fertilizer, apply farm manure 1000- 1500 kg per mu, compound fertilizer 40-60 kg, calcium superphosphate 40 kg, and then level the soil moisture. The soil moisture in winter and spring is gentle or low, and the width of soil moisture is 2.5-3 meters; The soil moisture content in summer and autumn should be divided into small moisture content and high moisture content, with the moisture content width of 0.8- 1 m and the ditch depth of 20-30 cm.

4. Sowing: The sowing amount of Xiaoqing (white) vegetables is 0.75- 1 kg in winter and spring, and 1.5-2 kg in summer and autumn, which can be broadcast or on demand.

Five interplanting seedlings: the first interplanting with 2-3 leaves, the second interplanting with 4-5 leaves, and the seedlings with 5-6 leaves. Spacing between seedlings is 20-24cm in autumn and 15- 18cm in winter.

Six times of irrigation and topdressing: topdressing for the first time when pulling the cross, and mixing 500 kilograms of water with 5 kilograms of calcium superphosphate and 5 kilograms of ammonium bicarbonate to raise seedlings; After the seedlings are fixed, 500 kg of urea and 5 kg of potassium sulfate are added with water for topdressing, and then topdressing is performed once every 10- 15 days, with urea 15-20 kg per mu. Topdressing should be combined with irrigation to keep the soil moist.

Pest control: The main diseases of Xiaoqing (Chinese cabbage) are black spot, white spot and anthracnose, which can be controlled by chlorpheniramine 800- 1000 times or thiophanate-methyl 70% 1000 times or carbendazim 50% 1000 times. Pests such as aphids, Plutella xylostella, Pieris rapae and striped flea beetle should be found and prevented in time.

8. Harvest: The harvest period of Xiaoqing (white) cabbage depends on the variety characteristics, cultivation season and market demand. Chinese cabbage can be harvested 30-40 days after sowing in autumn, 50-60 days after complete growth, and more than 100 days after sowing in winter and spring. You can harvest intermittently or at one time.

3. About the growth conditions of planting small vegetables

1, temperature

Chinese cabbage is a cold-loving crop with strong cold resistance. According to the experiment, the lowest temperature of seed germination is 3-5℃, and it can emerge in 3 days at 20-25℃. Flowering period 14- 18℃, pod development period 12- 15℃, with large temperature difference between day and night.

Step 2: Moisture

Vegetables have a long growth period, large vegetative body, many fruiting organs and need more water. The requirements for water in each growth stage are as follows: (1) In general, the soil moisture in germination stage should be kept at about 65% of the field capacity; The flowering period in bud stage is 75-85% of the field capacity, and the pod development period is 70-80% of the field capacity.

3. Fertilizer

According to the determination, the ratio of nitrogen, phosphorus and potassium per 100 kg of green rape is 1:0.35:0.95, and the demand for three elements is more than three times that of cereal crops.

4. Land

Chinese cabbage is a straight-rooted crop with developed root system, deep taproot, many branches and thin roots. It requires deep soil layer, good structure, rich organic matter, loose and breathable loam. In weak acid or neutral soil, it is more beneficial to increase yield and oil content of rape.

5. Regional differences

The growth period of Chinese cabbage varies greatly. The growth period of northern spring cabbage is 60- 130 days; Winter cabbage 130-290 days. Chinese cabbage developed obviously in stages. The vernalization stage of winter Chinese cabbage needs 0- 10℃ and 15-30 days. Spring type is between spring and winter type, and the temperature requirement is not obvious. Chinese cabbage is a long-day plant, and the daily sunshine hours are 12- 14 hours, which can meet the sunshine requirements. If the sunshine is increased, it can blossom and bear fruit in advance. Instead, it will delay development.

4. How to grow small vegetables?

1. As long as the sun shines properly, the soil of the land contains more nutrients, which is beneficial to drainage and water storage. Turn the ground with a shovel, the shovel depth is about 10 cm, and turn it for 3 ~ 5 days. Then, an appropriate amount of base fertilizer is applied to the soil, and the fertilizer is buried under the soil to level the soil.

2. Mix the seeds with fine soil, spread them evenly on the flat soil, then spread a thin layer of soil on the seeds and pour enough water, then cover them with plastic film, and compact the surrounding of the film with soil. After the seedlings grow, we need to water them again to promote the growth and development of Chinese cabbage seedlings. When there is too much water, drain it in time, and don't let the little vegetables drown. The next step is fertilization. The first fertilization after emergence can be watered with feces and urine, and then fertilized according to the growth of small vegetables.

3. After germination, check whether the soil is dry and short of water. If the soil is dry, spray water again and cover it with plastic film. After 3 or 4 days, vegetables will grow big leaves. At this time, the plastic film can be removed, so that vegetables can get more sunshine and promote growth.

5. Planting method and time of green vegetables

Green vegetables are also called Chinese cabbage, rape, small rape and oilseed rape. They are also nicknamed rape. Brassica and purple cabbage are different from Chinese cabbage in that their leaves are frosted and their basal leaves are feathered.

The planting season is generally August-10, which can be planted every year, but the solar terms in autumn and winter are better, and the northern winter is suitable for indoor planting. Seedling raising method of green vegetables: it is suitable for direct seeding when the temperature is high, and can be transplanted after sowing when the temperature is low.

1. First, water the pot soil, mix the seeds with the fine soil and spread it on the soil surface. Cover the seeds with a little soil, not too thick. Spray the topsoil with a spray to keep it moist. Generally, germination takes about 3-4 days, and it takes about 1 week when the temperature is low.

You can also use the on-demand method, 2-3 capsules per hole, with a spacing of about 3-5 cm. The time interval can be shorter when the temperature is high and longer when the temperature is low. 2. Keep the soil moist at seedling stage, and water it in the morning and evening when the temperature is high 1 time.

After 2 weeks of germination, spray 1 diluted decomposed organic fertilizer with water. 3. 4-5 real leaves can be transplanted and planted, and the plant spacing depends on the variety size, generally around 15-20 cm.

Watering after planting, slightly shading, and normal management after survival. If transplanting is not needed, it is necessary to start thinning seedlings and leave larger seedlings.

The principle of thinning seedlings is to make the distribution of seedlings more uniform, and rows can be selected many times until the spacing is appropriate. Topdressing 1 times decomposed organic fertilizer after each thinning. Cultivation method of green vegetables in spring: 1, variety: The green vegetables cultivated in spring should choose varieties with strong winterness to avoid bolting.

Generally, varieties such as March Slow, April Slow and May Slow are selected in Shanghai. 2. Seedling raising: Make the seedling raising land into a 2-meter-wide border (flat ditch), and use decomposed organic fertilizer 1000kg per mu.

Sow in the first ten days to the last ten days of 10, and the dosage of seeds per mu is 0.3 kg, which is even and practical after sowing. After emergence, interplanting should be done for 2~3 times, and appropriate topdressing should be applied.

When the seedlings grow to 6-7 true leaves, they can be planted in the field. 3. Soil preparation: After ploughing in the field, apply 50 kilograms of special compound fertilizer for vegetables per mu as base fertilizer, and make a border (even ditch) with a width of 2.5 meters for planting.

4. Greenhouse seedling raising is slower in March than in1late October, and slower in May than in early February to late March. Plant spacing is slow in March 10 * 15cm, April 15 * 15cm and May 15 * 20cm.

5. Field management: topdressing once after planting live trees, and applying 5 kilograms of urea per mu. Apply it for the second time before the warehouse is closed, and apply 7.5 kilograms of urea per mu.

Pay attention to prevent aphids in March. 6. Harvesting: Harvesting in open field in March is slower than that in late February to late March, harvesting in greenhouse in April is slower than that in late March to early April, and harvesting in May is slower than that in late April to early May.

Remove the roots with a kitchen knife and clean vegetables will be on the market. Summer cultivation method of Chinese cabbage: 1, variety: select varieties with strong heat resistance and good quality as summer cultivation varieties, such as Kangreqing No.3, Wanghua, 605, etc.

2. Soil preparation: apply 40 kilograms of special compound fertilizer for vegetables per mu as base fertilizer, and make a border (flat ditch) with a width of 2 meters to make the border deep and high, so as to facilitate irrigation and drainage. 3. Sowing: Sow Chinese cabbage (called Chinese cabbage cultivated in summer) in batches from mid-June to early August, and spread it evenly. The amount of seeds depends on the purpose of cultivation, and the amount of seeds used as Chinese cabbage cultivation is 2.5~3 kg per mu.

The seed consumption of "one sowing and three selling" is 1.2~ 1.5 kg. The seed consumption of vegetable seedlings is 1 kg.

Insect-proof nets and sun-shading nets can be used to cover the whole breeding process, so as to achieve the purpose of using less drugs and not using drugs. 4. Field management: Chinese cabbage can be planted in cotyledons in time, with a seedling spacing of 3 cm, and then the seedlings are thinned after the true leaves appear, with a seedling spacing of 12~ 14 cm.

Topdressing after each thinning, and applying 6 kilograms of special compound fertilizer for vegetables per mu each time. Generally, transplanted Chinese cabbage is sown in late July, and the seedling age is 25 days. Transplanting is carried out in cool weather, the seedlings are pulled out in the afternoon, and then planted after 3 pm, and the density is 12~ 14 cm square.

Master the principle of light watering and frequent watering, and water before 8 am and after 5 pm to prevent vegetables from rotting. Attention should be paid to the control of aphids, Pieris rapae and Plutella xylostella.

Autumn cultivation method of green vegetables: 1. Variety: Generally, varieties with strong resistance to virus diseases, such as Dwarf Anti-Green and New Evergreen, are selected. 2. Seedling raising: clear the seedling raising site and sow in batches from early August to late September, with the sowing amount of 0.5-0.75 kg per mu.

Water 1~2 times a day after sowing. 2~3 times after emergence, the final seedling spacing is 3 cm square.

3. Soil preparation is the same as spring ploughing. 4. Planting: The planting time is generally from the first ten days of September to the first ten days of 165438+ 10, and the plant spacing is 20 * 25cm.

Water immediately after planting. 5. Field management: topdressing for the first time after living trees, applying 5 kilograms of urea per mu, and topdressing again before closing trees.

Water or irrigate in time in case of drought, and pay attention to the prevention and control of aphids and virus diseases. 6. Harvest: According to different planting periods, the harvest period is also different. Those planted in September can be harvested in 25-30 days.

It takes about 40 days to harvest 5438+1October planted in the first half of June, and 45 days to harvest 5438+1October planted in the second half of June to the first half of June165438+1October. Winter cultivation method of Chinese cabbage: 1, variety: evergreen in winter and slow in February. 2. Seedling raising: Seeding and seedling raising from late September to early October of/kloc-0, with sowing amount of 0.4-0.75g per mu and proper topdressing at seedling stage.

3. Land preparation: the same as spring ploughing. 4. Planting: The planting period of winter vegetables is from the beginning of June 1 1 to the end of June of the following year 1. When planting, plant deeply and densely.

To avoid freezing injury, the general plant spacing is: 8* 15~ 17 cm. 5. Field management: It is basically the same as spring ploughing. Cold protection measures can be strengthened, and the floating surface can be covered with non-woven fabrics.

6. Harvest: Winter vegetables grow slowly, and it takes 80~90 days from planting to harvest, which can be advanced or postponed according to market conditions.

7. What are the ways to grow small vegetables on the balcony?

Fast-growing vegetables with short cycle: small rapeseed, garlic, mustard, Qingjiang vegetable and oilseed vegetable with long harvest cycle: tomatoes, peppers, leeks, parsley and onions; Space-saving vegetables: carrots, radishes, lettuce, onions, ginger and parsley; Vegetables easy to grow: bitter gourd, carrot, ginger, onion, lettuce and Chinese cabbage; Insect-resistant vegetables: onions and leeks. Novices can choose vegetables or lettuce that are easy to grow.

For example, Qingjiang vegetable and Youmai vegetable, two kinds of fast-growing lettuce can be planted all year round, and grow rapidly, and can be harvested in about five or six weeks. Bitter gourd, onion, ginger, etc. It has strong adaptability and a special taste, so insects don't like to get close, and they can grow well without pesticides and fertilizers.

Different vegetables are planted on balconies with different orientations. Most vegetables and fruits can be planted on the balcony. The orientation determines the lighting conditions of the balcony, while the closeness of the balcony determines the temperature conditions of the balcony.

Chaoyangtai is the most ideal balcony for growing vegetables, with abundant sunshine and good ventilation. Almost all vegetables grow best in sunny conditions, so ordinary vegetables can be planted on the balcony facing south all year round, such as cucumber, bitter gourd, tomato, kidney bean, day lily, mustard, zucchini, green pepper, lettuce and leek.

In addition, aquatic vegetables such as lotus root, water chestnut and water chestnut are also suitable for planting on the balcony facing south. The balcony facing east and west is a semi-sunny slope, which is suitable for planting vegetables like onion, rape, leek, loofah, coriander and radish.

But in summer, the balcony facing west has a higher temperature, which makes some vegetables. Fast-growing vegetables with short cycle: small rapeseed, garlic, mustard, Qingjiang vegetable and oilseed vegetable with long harvest cycle: tomatoes, peppers, leeks, parsley and onions; Space-saving vegetables: carrots, radishes, lettuce, onions, ginger and parsley; Vegetables easy to grow: bitter gourd, carrot, ginger, onion, lettuce and Chinese cabbage; Insect-resistant vegetables: onions and leeks.

In addition, aquatic vegetables such as lotus root, water chestnut and water chestnut are also suitable for planting on the balcony facing south. The balcony facing east and west is a semi-sunny slope, which is suitable for planting vegetables like onion, rape, leek, loofah, coriander and radish.

However, in summer, the balcony facing west is exposed to the sun, and the temperature is high, which causes some vegetables to be sunburned by the sun, and the leaves will fall off lightly and die. Therefore, it is best to plant high-temperature resistant vines in the corner of the balcony. The balcony facing north has almost no sunshine in a day, and the choice of vegetables is the smallest.

Choose shade-tolerant vegetables, such as lettuce, leek, asparagus, Toona sinensis, dandelion, water spinach, auricularia, etc. In summer, if the opposite floor is a curtain wall glass floor, it will reflect strong light, which also needs to be guarded against.

Expert opinion pays attention to balcony bearing capacity. Director Yang of Hangzhou Mingpin Decoration said: We should pay attention to the bearing capacity when growing vegetables on the balcony, because the architectural structure of the balcony determines that it cannot bear too much weight. Placing a vegetable basin alone can reduce the pressure on the balcony unit area. Generally speaking, the bearing capacity of the balcony is no problem, but if a group of brick walls are built and vegetables are planted on them, it will be a challenge to the safety of the balcony.

In addition, the balcony floor should not be rebuilt too much to avoid damaging the waterproof layer, but it is still very troublesome to restore it. Taking balcony vegetable growing as a supplement to life, Professor He of Hangzhou Academy of Agricultural Sciences said: Generally speaking, balcony vegetable growing is a supplement to daily vegetable demand.

8. How to grow small vegetables

One characteristic: Xiaoqing (white) cabbage is relatively cold-resistant, belonging to direct root system, with shallow root distribution, soft leaves, large evaporation and high requirements for soil humidity and air humidity; The short growth period requires loose and fertile loam or sandy loam with convenient irrigation and drainage, which requires more nitrogen, followed by potassium and less phosphorus.

Second, select the varieties of Xiaoqing (white) vegetables suitable for local cultivation, and trim the geographical soil moisture: after harvest, turn over the ridge of the kang deeply, apply sufficient fertilizer, apply farm manure 1000- 1500 kg per mu, compound fertilizer 40-60 kg, calcium superphosphate 40 kg, and then trim the geographical soil moisture. The soil moisture in winter and spring is gentle or low, and the width of soil moisture is 2.5-3 meters; The soil moisture content in summer and autumn should be divided into small moisture content and high moisture content, with the moisture content width of 0.8- 1 m and the ditch depth of 20-30 cm.

4. Sowing: The sowing amount of Xiaoqing (white) vegetables is 0.75- 1 kg in winter and spring, and 1.5-2 kg in summer and autumn, which can be broadcast or on demand. Five interplanting seedlings: the first interplanting with 2-3 leaves, the second interplanting with 4-5 leaves, and the seedlings with 5-6 leaves.

Spacing between seedlings is 20-24cm in autumn and 15- 18cm in winter. Six times of irrigation and topdressing: topdressing for the first time when pulling the cross, and mixing 500 kilograms of water with 5 kilograms of calcium superphosphate and 5 kilograms of ammonium bicarbonate to raise seedlings; After the seedlings are fixed, 500 kg of urea and 5 kg of potassium sulfate are added with water for topdressing, and then topdressing is performed once every 10- 15 days, with urea 15-20 kg per mu.

Topdressing should be combined with irrigation to keep the soil moist. Pest control: The main diseases of Xiaoqing (Chinese cabbage) are black spot, white spot and anthracnose, which can be controlled by chlorpheniramine 800- 1000 times or thiophanate-methyl 70% 1000 times or carbendazim 50% 1000 times.

Pests such as aphids, Plutella xylostella, Pieris rapae and striped flea beetle should be found and prevented in time. 8. Harvest: The harvest period of Xiaoqing (white) cabbage depends on the variety characteristics, cultivation season and market demand.

Chinese cabbage can be harvested 30-40 days after sowing in autumn, 50-60 days after complete growth, and more than 100 days after sowing in winter and spring. You can harvest intermittently or at one time.

9. About the growth conditions of planting small vegetables

Key points of Chinese cabbage cultivation: ① varieties.

Choose Shanghai green, heat-resistant and white-resistant, which is cold-resistant, waterlogging-resistant, pest-resistant and so on. ② Fertilization and soil preparation.

To grow small vegetables, it is necessary to turn over the cultivation boundary again. Remove weeds and sundries in the field, and apply high-quality decomposed organic fertilizer 1500 kg and ternary compound fertilizer 50 kg as base fertilizer per mu.

(3) sowing. Generally, sowing is adopted, and sowing is carried out before June 10, with 0.5~lkg per mu. It is required to level the surface of the border with a shovel after the border is built, mix a small amount of dry fine soil with the seeds, and then sow them evenly.

Water 1 time in the morning and evening after sowing to keep the soil moist. If possible, you can use a sunshade net to cool down during the day, which is beneficial to the growth of small vegetables.

4 water lightly and water frequently. After the emergence of seedlings, dilute manure was applied with water once, and then only water was applied without fertilization, and water was used to adjust fertilizer.

⑤ Weeding and pest control. Before sowing, spray100 ~125ml butachlor EC with water. Be careful not to use acetochlor herbicide.

Spraying once after sowing or before 2-leaf stage to control flea beetle. There are a few pests, that is, Cai Xi, Lv Jing and other pesticides with high efficiency, low toxicity and low residue are sprayed with water for control.

Stop spraying any pesticides 15 days before harvesting, and advocate covering insect nets to prevent insects.
