Urea is applied in May, and phosphorus and potassium are applied in June and July. The young trees were reshaped. After planting Lycium barbarum, 3-5 stout branches were selected as main branches around the upper part of the trunk in the autumn of that year, and they were cut short at about 20 cm. When new branches appeared on the branches in the next spring, they were cut short at 20-25 cm as backbone branches. In the third and fourth years, we will continue to use the long branches on the main branches to expand, heighten and enrich the crown skeleton. After 5-6 years of plastic culture, it entered the stage of tree formation. Adult trees are pruned every spring, including dead branches, transverse branches and sprouting branches at the roots. In summer, dense branches are removed and sparse branches are kept, and overgrown branches, pest branches and needle-punched branches are removed. Prune completely in autumn, arrange the crown, and choose to keep good fruiting branches.
