Field management: combine weeding all year round, loosen the soil in time and water it appropriately according to the land situation. Full base fertilizer is applied in March every year, and scientific topdressing is carried out at the end of June and August. Nitrogen fertilizer was mainly applied in the early stage, and phosphorus fertilizer and potassium fertilizer were applied in the later stage.

Shaping and trimming:

Black Lycium barbarum bears fruit in the same year, and enters the full fruit stage in four to five years, and must be finalized three years before planting. In the year of planting, all branches are cut short at a height of about 30-40 cm, leaving 4-5 well-developed main branches as the first layer, and then leaving a layer every 30-40 cm, leaving 3-5 main branches on each layer. Finally, the whole tree is trimmed into an umbrella shape with three to four layers, and on this basis, it is properly trimmed and reshaped every year. After such pruning and shaping, each Lycium barbarum can have dozens of fruiting backbone branches, which can relatively maintain the yield. Pruning is very important to improve yield and cultivate large fruit Lycium barbarum.
