The latest course of fertilization techniques for persimmon trees

Persimmon is a deciduous tree plant, persimmon has wild trees all over the country, but now it is gradually moving towards the mode of artificial breeding. Persimmon trees have strong vitality and can survive for hundreds of years. The roots are well developed and have strong absorptive capacity, so they prefer weak acid soil, which is more beneficial to the absorption of fertilizer. Today, the editor brings you the fertilization technology of persimmon trees.

First, the fertilizer requirement characteristics of persimmon trees.

The origin of persimmon is in China, and there are wild persimmon trees along the Yangtze River. There are many varieties of persimmon, but they all have one thing in common, that is, their roots are very strong and developed, they can extend to nearly 3 meters underground, and there are few fine roots. However, the root contains a large amount of Dorin, which is difficult to heal after the root injury, so we should pay attention to the concentration and dosage of fertilization to avoid injuring the root. Persimmon has a strong adaptability, whether it is acidic or alkaline soil, can grow normally. According to the experimental investigation, it is necessary to produce one ton persimmon with nitrogen 8-9kg, potassium 6-7kg and phosphorus 2-3kg. Therefore, persimmon trees have the greatest demand for nitrogen.

2. Fertilization techniques of persimmon trees

1. Planting and fertilization

The root of persimmon tree is very developed, the main root is long and deep, but the lateral root is underdeveloped, and the fine root is little or no. Therefore, when planting, it should be much deeper than other tree species, put farm manure, calcium superphosphate and soil into the planting hole, and then start planting. This is beneficial to the growth and development of the root.

2. Base fertilizer

The basic fertilizer should be applied after the leaves of persimmon trees fall off from October to November in winter, and the method of applying base fertilizer should be ditch application to plough the soil in the orchard. It is mainly to apply farm manure, but it is best to mix phosphorus and potassium fertilizer with farm manure, and apply the corresponding amount of fertilizer according to the size and growth of each tree. Apply fertilizer to the ditch dug around the tree and stir with the soil, and then fill the ditch.

3. Topdressing

The main fertilizers used in topdressing are chemical fertilizers such as compound fertilizers, which are added to each tree according to the planting time and the size of the book. It also needs to be fertilized according to the varieties of persimmons, and early-maturing varieties should start topdressing around July. Late-maturing varieties should be fertilized for the first time in summer and the second before and after the Beginning of Autumn. However, it should be noted that the application of nitrogen fertilizer should not be too much, and the time should not be too late, otherwise the branches will not be full enough, which will affect the flowering and fruiting of persimmons. Make poor coloring and reduce the quality.

The root of persimmon is very long and perennial. It is necessary to plough the base fertilizer once a year, and some green vegetables can be planted between each tree as green manure. In case of continuous overcast and rainy weather, the orchard should be drained and watered in time, and the hot and dry weather should water the trees in time to ensure the normal growth of persimmons and achieve the goal of high yield.
