Ploughing and weeding 1 time in May, and applying sheep manure, manure and cake fertilizer as base fertilizer and topdressing in late June-10/early October 165438. Urea is applied in May, and phosphorus and potassium are applied in June-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.
3. In the 34th year, the method of the second year was followed, and the long branches on the main branches were continued to be used to make the crown skeleton bigger, taller and richer. 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.
4. Pruning principle: remove the old and keep the new, remove the disease and protect the health, remove the weak and protect the strong, so that the bearing branches are evenly distributed in the crown. It is required to cultivate more fruiting branches and cut off unfruitful branches.
