In the growth period, sparse and decrypt the collected branches and invalid branches, leave more branches on the windward side and less branches on the leeward side to promote ventilation and light transmission. Generally, a large number of hidden buds germinate after persimmon trees are pruned. In order to reduce nutrient consumption, useless buds should be erased before lignification. Long branches with growth space, especially white long branches, should be picked at 40 cm.
Persimmon trees are deciduous trees with many varieties. The leaves are oval or obovate, with fluff on the back and yellow-white flowers. Berries, oblate or conical, orange or yellow, are edible. Wood can be used to make utensils. Persimmon is a deciduous tree of Persimmon family, which originated in China. Its height can reach 15 meters. Its trunk stands upright and its crown is huge. Persimmons ripen in September and October.
Low yield, low nutrient consumption, high accumulation and large flower buds. Therefore, young trees should try their best to protect flowers and fruits, improve the fruit setting rate, increase the number of fruits, and make young trees not small. When pruning, pay attention to the backbone branches and large branches that need to be dropped or shrunk. If there are strong fruiting branches on it, it should be lightly blocked and slowly shrunk or motionless until the New Year's Eve. For cross branches and dense branches, temporarily keep the fruiting mother branches and remove the weak branches. In the treatment of branches, we should sparse more and cut less. Measures such as girdling, coring and pollination were taken at flowering stage to improve the fruit setting rate.
By thinning buds and fruits, the best time for thinning buds and fruits of persimmon trees begins when the first flower on the fruiting mother branch opens and ends when the second flower opens. Except for the 1 ~ 2 flowers that bloomed early on the fruiting branches, all the other flowers that bloomed late were thinned out, especially on the fruiting branches, only 1 bud was left, and all the others were picked. In addition, fruit thinning should be carried out at the end of physiological fruit drop (early and middle July). The number of fruits left during fruit thinning should be proportional to the number of leaves, and the most suitable ratio of leaves to fruits is 20∶ 1. Remove small fruits, deformed fruits, pests and diseases.
