Lycium barbarum branches have thin skin and low water content. If pruned too early, they will lose water, and the wound will dry up and it will not heal easily. Therefore, pruning should be completed before the sap begins to flow, and the principle of pruning old and weak trees early and pruning young and weak trees late should be mastered. Lycium barbarum L. mainly has natural happiness, natural semicircle and cone shape. The first two types are suitable for sparse planting gardens with row spacing of 1.5×2 meters, and the latter one is suitable for dense planting gardens with 300 plants per 667 square meters. The pruning method is as follows.

First, sparse branches

First, we should cut off dead branches, diseased branches, injured branches, acupuncture branches and horizontal branches, and then prune the over-dense fruiting branches. When thinning fruit branches, first remove missing branches, shady branches, back branches and twigs; Then return to the upper and middle branches; If it is still dense, loosen the branches on both sides, and after cutting, make the spacing between fruit branches 5 ~ 6 cm, and they are all white branches with full growth and strong fruit.

Second, deal with long branches

The long branches growing at the drooping part of the main branch are reserved as the extension branches of the main branch, and are appropriately shortened to stabilize the branch potential and extension direction; If there is space near the long branches, they should be appropriately cut short and cultivated into fruiting branches to expand the crown and increase the fruiting area; Unuseful long branches, cut off from the base.

Third, update and revitalize the results branch.

After two years of fruiting, the fruiting branches of Lycium barbarum bent and drooped, and the fruiting ability decreased. For this fruiting branch group, leave a short node of 3 ~ 5 cm. After germination in spring, select buds with suitable growth direction and strong position, and cultivate new fruiting branches by coring.

Fourth, update the culture fruiting branches.

Fruit-bearing branches of Lycium barbarum have different fruit-bearing abilities due to different varieties. Some can bear fruit for two consecutive seasons, some can only bear fruit for one season, or only bear small and few fruits at the top. Results The weak fruit branches were characterized by grayish brown branches, and the extremely short branches were obvious. This kind of fruit branch must be trimmed and updated in time. It is usually cut from the bent and drooping part of the fruit branch. The stout chop is 1/2, the weak chop is 2/3, and the excessively weak chop is only 5 ~ 6 cm. Shortness is lighter than weight.
