Pruning after harvest
If litchi wants to produce high yield, it needs to cultivate strong autumn buds and strong branches in time. Prune the fruit reasonably after picking. Firstly, pruning weak branches and pest branches to positions less than 0.4 cm; The second is to cut short thick branches in order to make the upper branches heavier and the lower branches lighter, improve the permeability between branches and promote their photosynthesis.
Adjust the autumn shoots of litchi in time.
Litchi varieties in different periods need to pull out the mother buds that are not suitable for fruiting in different periods, which is very helpful for high yield of litchi, so the common pests of litchi are beetles, roundworms and moths. After the occurrence of pests, you can use Shengfeng insecticide or Kung Fu and water to kill insects.
Pruning in the growing season is generally called summer pruning. It has quick response and strong effect, and is mostly used for young trees and flourishing trees to alleviate growth potential, promote flowering, or adjust the relationship between growth and fruit. Pruning methods in summer include coring, girdling and softening branches (deciduous fruit trees), timely "budding" and "spreading branches" (citrus), and picking and pruning fruiting mother branches (such as persimmon, chestnut and litchi) in combination with fruits. In addition, plant growth regulators can also be used to replace some summer pruning measures.
Cultivate strong branches
After fruit picking, it is very helpful to cultivate two or three autumn shoots in three months for high and stable yield of litchi. Pay attention to timely cultivation between varieties, because there are differences between varieties, and the effect will be better if cultivated several times.
These are the key techniques for high-yield cultivation of litchi. Farmers must master scientific cultivation methods if they want to grow high-yield litchi. I hope the above content will be helpful to everyone.
