Developing persimmon production is a good way for farmers to get rich, and according to years of experience, autumn and winter management is particularly important in persimmon production.

First, pull branches and pruning

1. The best time to pull branches in autumn is in September, and the main objects are main branches and auxiliary branches. The opening angle of the base main branch should be about 90 degrees, pull down less than 70 degrees, pull upward more than 70 degrees, and pull improperly to the left or right.

two。 The winter pruning of persimmon trees is beneficial to the early fruiting of young trees, the high and stable yield of adult trees, and the renewal and rejuvenation of aging trees. Winter shearing time is generally carried out after falling leaves to before sprouting in the following spring, pruning according to the difference of land, tree potential, diseases and insect pests. If persimmon corner spot and persimmon stalk insects are found to be seriously harmful, they should be pruned seriously, otherwise they should be trimmed lightly.

II. Fertilizer and water management

The suitable time for applying base fertilizer in autumn is from mid-late September to early October, when the microbial activity is exuberant and the organic matter decomposes quickly, which is beneficial to root absorption. Fertilizer is mainly organic fertilizer, and mixed with nitrogen, phosphorus, potassium and other available fertilizers. Water immediately after application. In the mountains where there is no water, snow can be deposited on the tree nests, ice can be put on it, and soil moisture can be increased to supply persimmon trees with water.

III. Pest control

There are many kinds of diseases and pests in persimmon, and cleaning persimmon orchard in autumn and winter is an effective period for prevention and control.

1. In autumn and winter, diseased fruits, persimmon stalks, withered branches and fallen leaves should be thoroughly removed, and the overwintering places of diseases and pests such as angular spot, round spot and anthracnose can be removed to reduce the harm of the following year.

two。 To control pests such as persimmon stem insect and paramecium, it is necessary to scrape off the old thick and warped skin on the trunk and big branch in winter, remove the insect fruit hanging on the persimmon tree, and destroy it centrally, combined with ploughing the land to eliminate overwintering insect eggs and reduce the number of diseases and insect pests.
