Whether Lycium barbarum can obtain high yield has a great relationship with pruning technology, and the correct pruning should start from the first year. When the trunk of the young tree is about 50 cm long, the top should be cut off, and 3 ~ 5 strong lateral branches should be selected as the main branches below the cut 10 ~ 20 cm, and cut short at 20 cm. In the second year, 3 ~ 4 new branches were selected from the main branches, and the branches were cut off at 20 ~ 25 cm to form backbone branches and small crowns. In the third year, in the same way, cut short the newly grown branches on the backbone branches cultivated in the second year. In the fourth year, it is mainly to enrich the grass-roots crown, that is, in the third year, the long branches are cut short to increase and expand the crown and enrich the crown skeleton. After 5 ~ 6 years, the fruiting area of the crown will be expanded. On the lower crown skeleton branch, select the upright branch near the center of the crown, pick the core at 30 ~ 40 cm, make it send out side branches, enrich the upper crown, and form the upper crown skeleton. After several years of shaping and pruning, the tree has basically been shaped, that is, it has entered the stage of becoming a tree. During the period of young trees, we should also pay attention to cultivating the soil. Because the trunk of young Lycium barbarum trees is thin, it is difficult to support a large crown, so a mound with a diameter of 50 ~ 60 cm and a height of 20 ~ 30 cm should be cultivated at the base of young Lycium barbarum trees to support the young trees from lodging.

Pruning of adult trees can be carried out in spring, summer and autumn. In spring, dead branches are mainly cut off; Pruning shall be carried out in the summer from May to June, mainly to cut off the overgrown branches. However, when the crown is vacant or bald, the overgrown branches should be retained, and the tips should be removed at an appropriate height to promote the development of lateral branches to fill the gaps or tips; Pruning in autumn from August to September is mainly to prune clustered branches, old and weak branches, pests and diseases branches, mutually rubbing branches and horizontal stripes, so that the crown branches are evenly distributed, ventilated and light-permeable, the nutrient consumption in the flowering and fruiting period is reduced, enough nutrients are concentrated for the growth and development of fruits, and the falling flowers and fruits are reduced to ensure stable and high yield every year.
