Shaping and pruning technique of Lycium barbarum

Last Updated: 2024/11/05, In order to have a high yield, Chinese wolfberry must first be cultivated into a good tree shape. Lycium barbarum has strong branching ability, luxuriant growth, and has the characteristics of blooming and fruiting twice a year. Poor management, shaping and pruning will not only affect the yield of the same year, but also make the tree senescence ahead of time. Therefore, reasonable shaping and pruning is an important measure for high and stable yield of Lycium barbarum. The main results are as follows: 1. The tree shape of Lycium barbarum should be cut into umbrella-shaped circles with three layers of fruiting branches. The Chinese wolfberry planted in the first year was topped and dried at a height of about 60cm above the ground in early spring, and 10 ~ 20cm under the cut mouth.

To be fruitful, wolfberry must first be cultivated into a good tree shape. Lycium barbarum has strong branches and luxuriant growth. It has the characteristics of flowering and fruiting twice a year. If it is not properly managed, shaped and pruned, it will not only affect the yield of that year, but also make the tree senescence ahead of time. Therefore, reasonable shaping and pruning is an important measure for high and stable yield of Lycium barbarum.

1, plastic

Lycium barbarum tree shape should be cut into umbrella-shaped round, 3-layer fruiting branch group with big top and small bottom. In the first year, 3~5 branches with uniform distribution were selected as the main branches of the fifth crown of Lycium barbarum L.

In the second year after planting, one upright branch from the upper part of the trunk is selected as the extended trunk, the top is cut at 120cm from the ground, and 3~5 branches from the top are selected as the second branch crown.

In the third year after planting, one of the erect long branches from the top of the center of the second layer crown was selected as the trunk, and the top was cut at 160cm from the ground. The top of the parent branch was selected as the main branch of the third layer crown.

2, pruning

Goji berries are usually pruned twice. Spring pruning is carried out before germination. First, the branches sprouting at the base of the main branch are removed, and then the dead branches, cross branches, excessive long branches, old and weak branches, lateral branches, pest branches and needle branches of the branch group are cut off, and then the healthy fruiting branch group is selected and shortened. In summer, the middle part of Hebei Province is generally cut in the middle and late July, cutting off the overdense branches, weak branches and excessive branches on the trunk or main lateral branches, and gradually renewing the fruiting branch group, especially in the vacant or bare parts of the crown, using the excessive branches to culture into new fruiting branch groups.

Lycium barbarum usually enters its peak fruiting period in 3~ 5 years, the tree vigor gradually weakens after 30 years, the tree vigor senescence begins after 40~50 years, and the pruning is improper, and the senescence begins about 20 years. Therefore, reasonable pruning is an important measure for stable and high yield of Lycium barbarum every year.
