How to manage a sweet persimmon tree in spring, how to manage a persimmon tree?

1. Apply sufficient base fertilizer in late September, after the persimmon fruit is harvested, and early October is the fertilization period. The specific amount of fertilizer depends on the strength of the tree, the size of the canopy, the amount of yield, and the level of soil fertility. Generally, 100 kg of organic fertilizer, 1 kg of diammonium phosphate and 1 kg of potassium sulfate are applied to each plant, and the ditch is open and the ditch is 30 cm deep for fertilization.

2. Protect the leaves from persimmon harvest to before the leaves fall off, the leaves still have strong photosynthesis and transpiration. Foliar spraying of 3% urea solution can improve the photosynthesis ability of leaves, facilitate the nutrient storage of trees, and promote flowering, fruiting and new shoot growth in the next year. 3. After falling leaves, prune and thin out diseased and insect branches, dead branches, overlapping branches, weak branches, long branches, etc., and other branches should be properly cut and retracted.

For the current year-bearing shoots, leave 2 to 3 buds stubbed at the base. The old branches that are too long and the large branches of the aging trees are shortened back to the places where there are new branches to promote the development of new branches. 4. Weeds, fallen leaves, residual persimmon pedicles, and diseased and insect branches in the pest control garden should be burned in a centralized manner to reduce the source of transmission.

Deep ploughing should be carried out in combination with fertilization. Whiten the trunk in time, mix with water, quicklime, salt, sulfur and animal oil to whiten it to prevent the invasion of diseases and insects and the occurrence of frost damage. 5. Pour the frozen water once before pouring the frozen water, then cover the rolling tray of each tree with 1 square meter of mulch, and then make a crescent ridge with a length of 80 cm to 100 cm and a height of 60 cm to 70 cm at the outer edge of the membrane on the northwest side of the trunk to protect the root neck of the young tree that is most susceptible to freezing and most afraid of freezing (the surface part above the root system, that is, the connection between the root system and the trunk).

The same goes for tree species

For the sowing of persimmon trees, the soil with loose and fertile soil and good drainage and irrigation conditions should be selected as a nursery. Before sowing, deep ploughing and fertilization are carried out, and 4000-5000 kg of rotted farmhouse fertilizer and about 10 kg of compound fertilizer are applied per mu.

Generally, it is sown in March in the spring, using wide and narrow rows, with a wide row of 40 cm and a narrow row of 15 cm. Fill the bottom water before sowing, and sow after the water seeps down, with a sowing rate of 10-15 kg per mu. When sowing, it is sown according to 30-50cm row spacing, and the sowing depth is 2-3cm, and finally covered with plastic film after sowing, which is conducive to improving the seedling emergence rate.

When 2-3 true leaves appear in the seedlings, the seedlings are thinned and the plant spacing is maintained at 10-15 cm. If there is a lack of seedlings and broken walls, it is necessary to replant in time. In June, 500-1000 kg of decomposed human manure and urine were applied once per mu, and combined with watering, cultivated and weeded.

When the seedling is 30 cm high, the topping is made to make the seedling thicker to facilitate grafting. Attention should be paid to pest control at the seedling stage.

During the growth period, the overly dense branches and ineffective branches should be thinned, and more branches should be left on the windward side and fewer branches on the leeward side to promote ventilation and light transmission. Generally, after pruning, the hidden buds will germinate in large quantities, in order to reduce nutrient consumption, the useless buds should be erased before lignification; Long branches with room to grow, especially long branches, should be topped at 40 cm.

If pruning is also required in winter and spring, pruning is mainly carried out during the winter dormant period.

The key points of spring pruning of persimmon trees are: thinning the upright branches, weak branches, over-dense branches, cross branches, overlapping branches, diseased and insect branches, etc., on the back, and improving the light in the canopy.

Here's how to manage it:

1. Fertilization. It should be applied before the nutrients are most needed, including the time when the fertilizer is decomposed. That is to say, when applying fast-acting fertilizers, it can be closer to the fertilizer demand period; If the delayed organic fertilizer is applied, it should take longer than needed, and if the organic fertilizer is unrotted, it should be applied earlier.

Generally, the base fertilizer is mainly organic fertilizer, which is applied before and after harvest (October-December), and the top dressing is mainly chemical fertilizer, the first time is applied after physiological fruit fall, and the second time is applied during the fruit expansion period.

2. Pruning (winter and summer pruning).

Pruning principle: cultivate the skeleton, open the angle, and shape the tree. and timely topping to promote the growth of fruiting mother branches; Proper pruning promotes transformation and lays the foundation for an early harvest. When pruning, according to the requirements of shaping, the branches with suitable parts should be selected as the main branches and side branches.

Pay attention to ventilation and light transmission, strengthen the renewal of fruiting branches, and make the fruiting parts as close to the backbone branches as possible.

Temperature: Persimmon trees grow and prefer warm environments, so the climate should be above 10 degrees Celsius, and in the south, they can be planted in areas with an average temperature of more than 19 degrees Celsius, with a maximum average temperature of 22 degrees Celsius. In the northern region, the average annual temperature is 10-13 degrees Celsius, and measures should be taken to keep warm in winter to avoid frost damage.

Watering: persimmon trees are oxidized daily, and regional precipitation should be emphasized, because persimmon trees have strong drought resistance, and in the southern region, they can be completely adapted to local extensive cultivation and can avoid artificial watering. The average annual rainfall in the southern region is 450mm, which can fully provide the growth needs of persimmon trees.

In the hot summer, if there is no rain for a long time, deep irrigation can be implemented to avoid the occurrence of difficult to grasp the roots and dry up, and if planted in a humid environment, drainage measures should be taken, and persimmon trees should not be in a waterlogged environment.

Light: Persimmon trees are light-loving plants, so they can ensure sufficient daily light, suitable for natural planting, and not suitable for survival and greenhouses. Ensuring normal light can improve the lesion phenomenon of persimmon trees, and the branches and leaves are thick, which can strengthen the differentiation of flowering and germination stages, and the fruit yield is higher and the fruit quality is better.

Soil: Persimmon trees have a strong root system, so they are extremely adaptable to the soil, and prefer mountains, hills and other environments. The soil depth is more than 1 meter, which is the best fruiting environment for persimmon trees.

The soil demand, its pH value, should be maintained at 6-7, and the salt content should be. 026 grams or less.

Fertilization is mainly urea, about 10 cm to 20 cm next to the tree, dig a pit to a depth of about 15 cm, and then fertilize and seal the soil. It is generally pruned in winter and spring!

Pruning, of course. Otherwise, it won't grow well.

Sweet persimmon trees are best to apply organic fertilizer in autumn. Sweet persimmon trees in the autumn (9-10 months) apply sheep pen manure, rabbit manure, pen manure, manure, human manure, biogas residue and other machine fertilizers (4-5 square meters per mu) plus an appropriate amount of potassium sulfate compound fertilizer (about 100 kg per mu, nitrogen, phosphorus and potassium ratio of 20:10:

20 or so) is best. Ditch and apply at the projection of the outer part of the canopy, and water it in time after fertilization. In addition, at the young fruit stage (June to August), 1-2 times of potassium sulfur silver co-fertilizer (about 80 kg per mu each time) was applied, and the yield increase effect was better.

Summary. Hello, the best time for fertilization of sweet persimmon trees is from July to August, when sweet persimmon trees need the most fertilizer, accounting for 70% of the annual absorption. It is necessary to apply nitrogen, phosphorus and potassium compound fertilizer, which is carried out by furrow application and deep burial.

The best time for fertilizing sweet persimmon trees is from July to August, and the sweet persimmon trees need the largest amount of fertilizer at this time, accounting for 70% of the annual absorption. It is necessary to apply nitrogen, phosphorus and potassium compound fertilizer bending socks, and use furrow application and deep burial method.

At the same time, sweet persimmon trees in the autumn (9-10 months) should also be applied sheep pen manure, rabbit manure, circle fertilizer, manure, human manure, biogas residue and other organic slag fertilizer (4-5 square meters per mu) plus an appropriate amount of potassium sulfate compound beam Bo Hefei (about 100 kg per mu, nitrogen, phosphorus and potassium ratio of about 20:10:20) is the best.

It is applied in a ditch at the peripheral projection of the canopy of the tree, and watered in time after fertilization.

Persimmon tree has a long history of cultivation in Weinan City, it is not only an important woody grain, but also a tree species for greening in barren ditches and barren slopes, the fruit color is beautiful, juicy and sweet, rich in nutrition, it can be eaten freshly, and it can be processed into a variety of products. In recent years, with the development of the market economy and the continuous improvement of the people's living standards, as well as the further adjustment of the rural industrial structure, Weinan City has actively developed the persimmon industry by relying on key forestry projects such as returning farmland to forest, "three north" shelter forests and yen loans, and has achieved significant economic benefits and obvious social and ecological benefits, and the persimmon industry has gradually become a pillar industry for the masses to get rid of poverty and become rich, increase income, and promote regional economic development. However, from the perspective of construction scale, industrial structure, management level, product competitiveness and comprehensive economic benefits, the construction of persimmon industry in Weinan City is still in the primary stage of development, and the industrial layout and variety structure are unreasonable, the extensive production management, the yield and high-quality fruit rate are low, and the degree of industrialization is low, and other factors seriously restrict the healthy development of the persimmon industry in Weinan City.

The current construction of the persimmon industry is far from meeting the requirements of market development and cannot meet the increasing material needs of the people. In order to further expand and strengthen the persimmon industry in Weinan City, help the masses solve technical problems in persimmon production and processing, improve the yield and quality of persimmon fruits, and increase the added value of persimmon product processing, Weinan Forestry Bureau organized technical personnel, summarized and absorbed the production experience of various places, in line with the principle of combining theory and practice, with practical application as the mainstay, compiled the book "Persimmon Cultivation Management Technology" to meet the needs of the current development of persimmon industry in Weinan City.

The contents of this book include: biological characteristics of persimmon trees, persimmon tree varieties, seedling cultivation, persimmon tree gardening, soil, fertilizer and water management, plastic pruning, pest control, harvesting and processing technology, etc. The text and pictures are rich and easy to understand, which can be used as a reference for forestry science and technology workers and the majority of persimmon farmers.

Persimmon is a very popular fruit because of its sweet and delicious fruit and beautiful shape, so many people want to grow persimmon trees in their homes or farms. However, the cultivation and management of persimmon trees requires certain skills. Here are some suggestions on how to manage your persimmon tree.

The first thing to pay attention to is to choose a suitable location for the growth of the persimmon tree. The most suitable environment for persimmon trees to grow is a place with a mild climate and fertile soil. When planting, you should choose a location that is exposed to sunlight and air circulation, so as not to affect the growth of persimmon trees.

Secondly, it is necessary to fertilize reasonably. The fertilization of persimmon trees can appropriately increase the proportion of organic fertilizer to ensure that the root system of persimmon trees grows further and absorbs more nutrients. In addition, in the growth process of persimmon trees, it is also necessary to pay attention to timely supplementation of mineral elements such as potassium dihydrogen phosphate and ammonium nitrate to enhance the growth ability of persimmon trees.

Again, pay attention to regular pruning. As the persimmon tree grows rapidly, the canopy needs to be pruned in time. The main purpose is to keep the canopy of the persimmon tree at the proper density and prevent it from being too dense to harm the growth of the persimmon.

In addition, regular pruning also helps to improve the yield and quality of persimmons.

Finally, pay attention to pest control. Persimmon trees often have problems with pests and diseases, such as persimmon insects, aphids, etc. In order to prevent these problems, it is necessary to clean up dead leaves and branches in the canopy in time to reduce the occurrence of pests and diseases.

In short, if you want the persimmon tree to grow healthy and bear fruit, you need to pay attention to the above points. Through scientific and reasonable management, I believe that persimmon trees will grow stronger.
