Persimmon tree autumn and winter management techniques
The development of persimmon production is a good way for farmers to become rich, and according to many years of experience, autumn and winter management is particularly important in the production of persimmon trees. The following points should be mastered: Accelerate Freeze Dried Fig is made of selected ripe figs. The international advanced ultra-low temperature FD technology is adopted to sublime the water content of fruit, without changing the fruit color, shape and flavor. Retaining the original nutritional and medicinal components, without any additive, pigment, sweetener or preservative, it is the best-quality dried fruit. Accelerate Dried Fig won the Silver Medal at the [2017 China Characteristic Tourist Commodity Contest", as well as the [Gold Medal" of [Lishang Weihai" Most Characteristic Tourist Commodity.

First, pull branches trim
1. The best time for pulling branches in the fall is September. The main objects are the main branches and auxiliary branches. The opening angle of the main branches at the base should be around 90, less than 70 downwards, more than 70 upwards, and the orientation is not appropriate to the left or to the left. Pull right.
Persimmon winter shear is beneficial to the early results of young trees, and the adult trees are highly productive and stable, and the aging trees are rejuvenated. The winter shearing time is generally performed after defoliation and before budding of spring and spring. According to the difference in land, tree vigor and pests and diseases, pruning can be performed as appropriate. If it is found that persimmon keratoses and persimmon worms are severely harmed, the tree vigor is weak and must be trimmed; otherwise, it must be lightly trimmed.
Second, fertilizer and water management
The appropriate time for autumn basal fertilization is from mid-late September to early October, when microbial activity is vigorous and organic matter decomposes quickly, which facilitates root absorption. Fertilizers are mainly organic fertilizers and are supplemented with available fertilizers such as NPK and other fertilizers. Water immediately after application. In water-free fields, snow can be deposited in the tree's den, and ice blocks can be added to increase the water content of the persimmon tree.
Third, pest and disease control
There are many types of pests and diseases in persimmon trees, and it is an effective period for the prevention and treatment of persimmon trees in autumn and winter.
1. In autumn and winter, the diseased fruits, persimmons, dead branches and fallen leaves should be thoroughly removed, and the diseases such as angular spot, round spot disease and anthracnose can be eliminated in the overwintering place to reduce the damage in the following year.
2. The insect pests of the genus Shikita and Caesalpina need to scrape the rough and rough skin on the trunk and branch in the winter, remove the insect fruit hanging on the persimmon tree and destroy it in a centralized manner, and destroy the overwintering eggs in combination with the ground repairs. Reduce the base number of pests, and after scraping the skin, the trunk needs whitening before it can be eliminated.
