1, and seedlings can be raised in spring and autumn. Nursery land should be selected in sandy loam with flat terrain, good drainage and irrigation conditions, convenient transportation and deep soil layer as nursery land. Remove the grass roots from the nursery, apply decomposed farm manure, preferably sheep manure, and apply 20-30 kg of NPK compound fertilizer according to the amount of 2000 kg per mu, and rake the ground in time after fertilization. The seedbed is a low bed with a bed width of 1.2m and a bed height of 15cm, and a working channel with a width of 40cm is reserved between the two beds for walking management. Irrigate the seedbed before sowing, and sow in 2-3 days after irrigation. Disinfect the seeds with potassium permanganate solution before sowing, then spread the seeds evenly on the bed at the dosage of 0,8-10.5 kg per mu, and cover them with fine sand of 1- 1 0.5 cm. Spray clean water on the sand surface every two days or so until the seedlings appear. In addition, drilling and hole sowing can also be used. You can also use containers to grow seedlings in the greenhouse, and when the seedlings are about 20 cm high, they can be moved out of the greenhouse and planted in the ground.

2. Cutting can also be carried out before germination in spring and autumn. Select 1 year-old tendril branches or stout branches with full buds on excellent single plants, cut into cuttings with the length of 18-20 cm, insert the cuttings obliquely into the whole border, and compact firmly. Pay attention to frequent watering to keep the soil moist, and the general survival rate is about 85%. In addition, the root system of Lycium barbarum fruit is developed and the root system has strong shading ability. By cutting off the taproot, many new seedlings can be shaded around the taproot and cultivated after tillering.

3. Planting density: The reasonable planting density of Lycium barbarum is 440-700 plants per mu. It can be cultivated reasonably according to the row spacing of 1.5 (or 1.2) meters and the plant spacing of 1 (or 0.8) meters, which will not affect the growth and fruit picking of Lycium barbarum and will not waste land resources.

4. 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.

5. Plastic pruning: Lycium barbarum bears fruit for three years, and enters the full fruit period in five years. Its molding must be completed in the first three years of 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 three to four layers of umbrella, 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.

6. Harvesting and processing: Harvesting of Lycium barbarum should be between awn seed and autumnal equinox. Pick ripe fruits in time and dry them in the shade or in the sun. Should not be exposed to the sun, so as to avoid excessive drying, be careful not to rub with your hands, so as not to affect the quality. When it is rainy in summer, it can be dried with warm fire.
