How to plant magnolia

Question 1: How to plant magnolia? Magnolia grandiflora can be propagated by grafting, layering, cutting and sowing, but grafting and layering are the most commonly used methods.

(1) Grafting propagation. There are two grafting methods, one is butt joint and the other is cutting.

Docking: docking time, from spring to autumn, can be carried out throughout the growing period. Mostly in April-July. The best abutting position is 70 cm from the ground. After binding, wrap it in mud and leaves to prevent the rain from washing away. It can be cut off in about 60 days. Docking is an easy way to live, but it is not as vigorous as cutting.

(2) Layered propagation. There are also two kinds of stratified communication: ordinary stratification and college stratification.

① General stratification: stratification is best carried out in February-March. Cut the root of the branch to be pressed half deep, then cut it up for a while, and then press a tile in the middle, so it won't break. Insert a thick U-shaped iron wire into the soil, fix it to prevent it from lifting, and then pile it on the soil. Layering in spring, and cutting and planting after the root buds are sent out.

② High-branch layering: Before lodging, select healthy and disease-free shoots (diameter 1.5-2cm) on the mother plant, cut cracks at the lower part of the pot fork, then cover it with a bamboo tube or bottomless pottery jar, fill it with culture soil, and tie it tightly with a string outside, be careful not to touch it, and spray a small amount of water frequently to keep it moist. New roots can be born around May of the following year, and then they can be taken off for colonization.

Magnolia likes sunny and humid environment and should not grow in alkaline soil for a long time. Planting should choose a place that is sheltered from the wind and sunny, well drained and fertile. There should be enough water and fertilizer before flowers to make them big and fragrant. There are not many branches of Magnolia grandiflora, except dead branches, pests and diseases branches and branches that disturb the tree shape, which generally do not need pruning. If the flowers wither without leaving any seeds, cut off the fruit to avoid consuming nutrition. Magnolia grandiflora has strong cold tolerance and can overwinter in the open air in North China and the southeastern part of China.

Potted Magnolia grandiflora can be coiled, that is, after germination in April, with the growth of new shoots, it can be coiled at any time and tied into an arc posture to limit the height of the trunk. Because magnolia is a deep root system, it is easy to grow and weaken after a long time in the pot. Therefore, after the flowers wither, it is necessary to repair the taproot, cultivate it in the field, and then put it in a pot before the flowers, so that there can be more flowers and more flowers.

Magnolia grandiflora is mainly propagated by grafting, but also by sowing, cutting and layering. The seedlings of Magnolia grandiflora are often used as rootstocks for grafting, and they are cut before Tomb-Sweeping Day. In the south, it can also be cut around the autumnal equinox or germinated in August-September. Cutting and budding are the same as common flowers and trees. Seeding at the end of September or the beginning of 10, picking mature fruits, taking out seeds, soaking in plant ash water for 1-2 days, rubbing off waxy arils, and washing with clear water to sow; You can also clean the seeds and store them in wet sand, otherwise the germination ability of the seeds will be easily lost. In March of the following year, indoor potted plants can be planted, and seedlings can emerge in about 20 days.

Question 2: How to plant magnolia trees? The propagation of Magnolia species such as Magnolia and Magnolia is usually carried out by sowing, grafting, cutting and tissue culture. 1. Sowing must master the maturity of seeds. When the seeds turn red and burst, they will be harvested immediately. Early harvest will not germinate, and late harvest will easily fall off. Thinning after harvesting, soaking the fruit with red exocarp in cold water, kneading, removing exocarp, taking out seeds to dry, storing in sand, and planting in February-March of the following year. The height of annual seedlings can reach about 30 cm. Transplant in the spring of the second year after cultivating big seedlings, cut off the main roots properly, and then apply base fertilizer to control the density. Qualified seedlings with complete crown, sparse buds and plant height of more than 3 meters can be cultivated in 3~5 years. After 2~3 years of colonization, it can enter the full flowering period. This kind of seedling has strong growth potential and adaptability, and its effect is no less than that of grafted seedlings. 2. Grafting usually adopts Magnolia plants such as Magnolia grandiflora and Magnolia officinalis, and the methods include cutting, splitting, abdominal grafting and bud grafting. The survival rate of splitting is high and the growth is fast. The survival rate of grafting in late autumn is more secure than that in early spring. 3. Cutting This is the main propagation method of Magnolia grandiflora. Cutting time has a great influence on the survival rate, generally from May to June, when young trees have the highest survival rate. Soaking in 50ppm NAA for 6 hours can improve the rooting rate. 4. layering is a traditional breeding method, which is suitable for preserving and developing famous varieties. This method is most suitable for magnolia purpurea. Select plants with good growth, and take 1~2-year-old branches with the thickness of 0.5 cm ~ 1 cm as layering. If there are branches, you can press on them. Stratification time is February-March. Rooting in the same year after pressing, the longer the connection time with the mother plant, the more developed the root system and the higher the survival rate. Flowers can bloom 2~3 years after planting. 5. Tissue culture In recent years, the method of tissue culture was adopted, and the buds of Magnolia officinalis were used as explants and successfully cultured in test tubes. This method is of special significance for the preservation and development of new varieties bred by bud mutation and hybridization.

Question 3: What are the planting conditions of Magnolia grandiflora? The choice of planting environment is magnolia likes light, young trees are more resistant to shade, not resistant to strong light and western sun, too strong light or western sun, easy to burn trees. Magnolia grandiflora can be planted in the shade of the side, but it will not grow well under big trees or in the shade, with thin trees, sparse branches, yellow leaves, no flowers or small flowers; Magnolia grandiflora is cold-resistant and can withstand a short-term low temperature of -20℃, but it should not be planted in the tuyere, otherwise it will be easy to pull weeds, and it can survive the winter safely in the open field in the lee and sunny areas of Beijing without winding and other measures. Magnolia likes fertile, moist and well-drained slightly acidic soil, but it can also grow normally in mild saline-alkali soil (pH 8.2, salt content 0.2%). Magnolia grandiflora is a fleshy root and is afraid of water accumulation. Planting in low-lying areas is easy to rot and lead to death. Magnolia grandiflora has good soil permeability, but it grows poorly in clay, and grows best in sandy loam and yellow sandy soil.

Question 4: How to plant the Dreamy Magnolia Westward Journey? Flowers in dreams are in various ways.

Operation method on the first day (when planting): Three fertilizers (be sure to check for bugs before 12 pm).

Operation method after the second day:

The country is thriving ―― healthy and strong, with two waters and one fertilizer.

The country is on the verge of death-three waters and three fertilizers

Never forget, once you become a smiling face and become rich ~ then don't gild the lily before watering or fertilizing ~ just kill insects.

Plant dormancy:

Life of first-class plants: growth, flowering, fruitlessness, dormancy and withering.

Life of secondary plants: growth, flowering, fruiting, dormancy, fruiting, dormancy and withering. Harvest twice, two fruits at a time.

The life of tertiary plants: growth, flowering, fruiting, dormancy, fruiting, dormancy, fruiting, dormancy and withering. Harvest three times, two fruits at a time.

Four-level plants bear fruit four times in a lifetime and sleep four times.

When plants are dormant, they also need to be taken care of.

If your plant goes into hibernation, check it every day.

Under normal circumstances, plants go into dormancy on the first day, and the state of system brush is crying. At this time, although the system does not brush 0 water and 0 fertilizer, it needs to give two water and one fertilizer. Normal plants lie dormant for a day or two. The principle is to look, you don't need to water the smiling face, you need to water the crying face.

If you don't care during the dormancy period, it will greatly increase the dormancy period of plants.

Fruit of a plant:

From the second day after flowering, you can try to pick fruits every day.

Secondary plants can get four fruits normally. I am in grade 152. Eating a fruit is about 4W experience and 2W money.

Three-level plants can get six fruits normally. I eat a fruit 7W, about 4W5.

Fruit can't be given away or traded, you can only grow it yourself and eat it yourself, but fruit has a shelf life, so you should eat it while it is fresh.

Gems, seeds, strengthening stones and C66 can all be eaten in fruits.

Question 5: How to plant magnolia seeds? I planted them for two weeks before they were born There must be enough water, and no water can accumulate.

Question 6: How to maintain potted magnolia? Magnolia is an evergreen tree, which is warm and humid, not cold-resistant, not drought-resistant, fragrant and white as jade.

How to make potted magnolia large, flowery, fragrant, gorgeous and long, the key is to strengthen the flowering management of potted magnolia.

1, the light is suitable.

Magnolia is a sunny flower and needs plenty of sunshine. During its growth period, it should be placed on the balcony or sunny ground with long sunshine time, especially in flowering period. The daily light shall not be less than 6 hours.

If Magnolia grandiflora is kept in the shade, it will only grow leaves without flowers, or have few flowers, slender branches, light leaves and thin and dull leaves, which is very unfavorable for its growth.

However, in the "dog days" of hot and high temperature, it is still necessary to shade moderately. Generally, every day 12- 16, it is necessary to avoid sun exposure and high temperature radiation of brick walls or cement floors.

At this time, it is necessary not only to spray water on plants to cool down, but also to water the ground or spray water to cool down and dissipate heat, increase air humidity and artificially create a suitable environment.

2. Water it in time.

Magnolia is a fleshy root, which needs water and is afraid of water accumulation.

Therefore, from early summer to late autumn, water should be poured once a day to keep the soil moist, but in hot days, water should be poured once in the morning and evening, and water should be sprayed on leaves and flowerpots to increase the air humidity.

When pouring magnolia with tap water, we should pay attention to prevent soil alkalization. If the leaves are found to be yellow, the roots should be watered with ferrous sulfate water or 0.7% ~ 0.8% acid vinegar water.

You can also spray leaves with 0.3% to 0.4% acid vinegar, and the effect is also very good. In spring and rainy season, flowerpots can't accumulate water, otherwise the roots will rot.

3, to make up the nutrients.

This is an important part of flowering management. Magnolia is a fertilizer-loving flower because it has a long flowering period and many flowers.

To this end, it is necessary to supplement nutrition in a timely and regular manner in order to blossom more, with large flowers, colorful flowers and fragrant flowers.

In addition to applying base fertilizer on the pot, organic liquid fertilizer mainly containing phosphorus and potassium, such as decomposed cake fertilizer and water, should be applied once every 5-7 days from May to June in 65438+/kloc-0.

The principle of fertilization is to apply thin fertilizer frequently, or you can adopt the method of thinning first and then thickening. Never apply fertilizer, or you will burn the roots.

At the same time, topdressing outside the roots every 7 days to 10 days, spraying 0.5% plant growth promoter and 0.3% potassium dihydrogen phosphate on the leaves.

4. Pick leaves and cores

Yulan leaves the room between the vernal equinox and Qingming every year. Choose cloudy or cloudy weather to leave the room. After leaving the room, let the potted plants adapt to the outdoor environment for 2 to 3 days, and then start to remove the old leaves of the plants, leaving only a few tender leaves on the branches to promote the production of new buds.

Then after each batch of flowers, a small amount of old leaves should be removed to promote the growth of new branches and the formation of flower buds.

In the growth period of Magnolia grandiflora, we should also regularly pick the top, control the top advantage and promote multiple branches.

5. Control pests and diseases

The pests of Magnoliae are mainly aphids and scale insects.

Spraying with 0.3% to 0.4% acid and vinegar or scratching with hands can kill the harm of scale insects.

Aphids are harmful to buds and buds. You can kill pests quickly, or spray 500 times of washing powder solution, or dip cotton swabs in washing powder solution to remove pests, and then spray clean water to wash branches and leaves.

In the process of magnolia management, besides yellowing and root rot, attention should also be paid to the prevention and control of anthracnose.

Question 7: How to plant and store magnolia seeds? After 20 days in the shade, the seeds were basically dry. You can put it in a plaque or in a bag, but the mouth of the bag should not be tied tightly to facilitate ventilation. When the average temperature of the day is below 5 degrees, it can be stored. Magnolia grandiflora seeds should be stored in low temperature and wet sand to simulate the natural environment and promote the seeds to germinate neatly in the coming year. Sand can be used in ordinary river sand or washed. Moisture should be kneaded into a ball and dispersed by friction. Layers of sand and seeds are stacked indoors, and the thickness of each layer of sand is 2-3cm. Pay attention to keep humidity when storing. It is suggested to change the sand every 15-20 days to pick out the seeds with water and more gravel on the seed coat. These seeds often rot, which will affect other seeds. The quality of storage directly affects the germination rate and must be treated with caution. Sowing time can generally be carried out after the Spring Festival, not later than Qingming. Of course, this is based on the climate in East China. Going further north can be postponed and going south can be advanced. Traditionally, sowing is accomplished by drilling and transplanting in the second year. However, in my opinion, it is best to sow the seeds and transplant them after emergence. Because of the high fat content of Magnolia grandiflora seeds, squirrels and other rodents like to eat them very much. Therefore, measures such as film mulching should be taken to prevent it from sowing to emergence. After the seedlings germinate, they can be transplanted when there are two real leaves, and the plant spacing is 25*25. Note that Magnolia grandiflora is a fleshy root. No matter where you plant and cultivate, you should choose a place with higher terrain and no water. Magnolia grandiflora is an excellent tree species for landscaping and has a long history in the market. In recent years, some species of Magnoliaceae, such as Michelia Lechang, Manglietia honghuaensis and Parakmeria ledong, have become increasingly popular, even in short supply. The methods mentioned above can also be used for seed treatment of these tree species, and I hope this paper can help those nursery producers. tieba.baidu/f? kz = 128753725

Question 8: How to plant a Magnolia grandiflora? This is the main breeding mode of Magnolia grandiflora. Cutting time has a great influence on the survival rate, generally from May to June, when young trees have the highest survival rate. Soaking in 50ppm NAA for 6 hours can improve the rooting rate.

Cutting is also divided into time.

Cutting propagation method

Cutting, also known as cutting, is a common propagation method for cultivating plants. Stems, leaves, roots, buds, etc. Some plants can be cut off (called cuttings in gardening), or inserted into soil, sand, or soaked in water, and can be planted after taking root, making it an independent new plant. In agricultural and forestry production, different plants have different requirements for cutting conditions. Only by understanding and adapting to their needs can we achieve a higher reproductive success rate.

Shoots are cuttings with leaves during the growing period of plants (the most suitable in rainy season). Select the semi-mature branches of the year as cuttings, the length is generally about 10 cm, and each cutting belt is guaranteed to have two or three leaves, so as to make nutrients through photosynthesis and promote rooting. If the blades are large, only one blade can be left or a part of the blades can be cut off to reduce evaporation. It is best to choose the stem tip of the tender branches of herbs, which can greatly improve the survival rate and quickly obtain the ideal plant type. Cutting of purple-backed sunflower belongs to softwood cutting.

Water insertion method is to soak the base of cuttings in water, change the water regularly, and transplant them into the soil after rooting. The stems and leaves of watercress green can be inserted in water.

In order to ensure the survival of cutting, we must pay attention to the following key issues:

1. Selection and treatment of cuttings. Choose strong branches without pests and diseases as cuttings. After selecting cuttings, handle them carefully. The tender cuttings should be cut immediately after harvest to prevent wilting from affecting survival. Succulent plants (such as cacti). ) should be cut and put in a ventilated place to dry for a few days, and then cut when the incision shrinks slightly; Or barbecue the incision slightly with a small fire to prevent decay. Generally, if the lower incision of plant cuttings is stained with some freshly burned plant ash, it can also prevent rot.

2. temperature. Generally, the cuttings of plants take root fastest at 20 ~ 25℃. If the temperature is too low, it will take root slowly, and if the temperature is too high, it will easily cause cuttings to rot. Therefore, if the temperature is artificially controlled, cutting can be carried out all year round. Under natural conditions, the temperature is suitable in spring and autumn.

3. Humidity. Care should be taken to keep the cutting substrate moist after cutting, but it should not be too wet, otherwise it will cause rot. At the same time, pay attention to the humidity of the air. We can cover it with plastic film to keep the humidity, but we should pay attention to ventilation for a certain period of time.

Question 9: How does Magnolia achieve a high survival rate? Magnolia grandiflora is an evergreen tree of Magnoliaceae, with thick leathery leaves and fragrant white flowers, and likes moist and fertile soil. The branches are straight, the leaves are bright green, and the huge white flowers are favored by people. The key points of planting technology of Magnolia grandiflora are introduced as follows:

Season: Early spring is suitable for transplanting magnolia trees. About half a month after the Spring Festival, Magnolia grandiflora is still in dormancy, with slow sap flow and slow metabolism, so it can be transplanted at this time. After transplanting, the temperature rises in spring that night, and the roots germinate, grow and repair first. If properly managed, the growth of Magnolia grandiflora in that year will basically not be affected. In addition, the rainy season is heavy and the air humidity is high. At this time, the survival rate of transplanted Magnolia grandiflora is very high.

Pruning: By pruning and picking leaves, water evaporation can be reduced, and the pressure of water supply for injured roots can be reduced. When pruning, we should cut off overlapping branches and diseases and insect pests, and strive to maintain the integrity of the tree.

Soil ball: Generally, the diameter of soil ball is 8 times to 10 times of the DBH of trees, which can ensure that the root system is less damaged and the trees are easy to recover. The soil ball is too small, the root system is seriously damaged and it is difficult to absorb water, which affects the survival of trees. The soil ball should be tied tightly with straw rope to avoid loosening during transportation.

Moisturizing: After transplanting Magnolia grandiflora, the first root watering should be timely, and the watering should be sufficient and thorough, so that the root system can fully contact the soil, which is beneficial to the survival of the tree.

Question 10: How to plant magnolia trees? Key points of magnolia tree planting:

1, planting magnolia requires soil balls, and bare-root planting is not easy to survive.

2. Spring planting should be done before flowers wither and leaves unfold, and autumn planting should be done in late September.

3. before winter comes, cut off the peripheral roots for transplantation next year. When transplanted, the root wound can heal and some new roots can grow. Some leaves should be removed before emergence to reduce evaporation. Organic fertilizer should be applied to planting holes to promote the formation of plants as soon as possible. After planting, make a tree pot, water it once a day for three consecutive days, and loosen the soil in the pot on the fourth day to keep it moist.

4. Magnolia grandiflora is native to the Yangtze River valley in China, and its cold tolerance is limited. It should be planted in a small courtyard in the north facing the sun or on the south side of a building, which can naturally overwinter.
