Propagation method of Lycium barbarum
First, the selection and preparation of land is generally cultivated with non-cultivated land, and the loose, fertile and well-drained sandy loam soil is better. When preparing the soil, it is best to apply base fertilizer, rake fine and level it deeply, and make the border 1.2-1.5 meters wide. Drains can be opened on slopes instead of beds.
Second, the method of reproduction (1) sexual reproduction. It can be sown in spring, summer and autumn, and the sowing amount per mu is 1-1.5 kg. According to the row spacing of 40 cm, the sowing depth is 1.5 cm, and the soil cover is 1 cm thick after sowing. (2) asexual reproduction. It can be propagated by branch cutting, crimping and grafting. It is common to raise seedlings by cutting.
Third, field management (1) seedlings. When the height of the seedling is 3 cm to 6 cm, the distance between the seedlings is 6 cm and 9 cm. When the height of the seedlings was 6 ~ 9 cm, the distance between seedlings was 12 ~ 15 cm, leaving 10 ~ 12000 seedlings per mu. (2) cultivate soil. When the young tree grows to about 1 meter high, a mound of 50 cm in diameter and 20 cm in height can be built at the base of the trunk to prevent the tree from falling and bending. (3) fertilization. Compound fertilizer was applied once in late June and early July respectively. The application of 15-20 kg per mu for big trees and about 6 kg per mu for young trees. Base fertilizer was applied from late October to early November, and then irrigated in winter. Base fertilizer can be used with sheep manure, pig manure, barnyard manure, cake fertilizer and so on. (4) shaping and pruning. After the Chinese wolfberry was planted, it was dried at a height of 50 cm from the ground. in the autumn of that year, 3 or 5 sturdy branches were selected around the upper part of the trunk, and cut short at about 20 cm from the ground.

Cultivation of high yield and high quality of Lycium barbarum
Lycium barbarum is a deciduous shrub of the genus Lycium barbarum of Solanaceae. Its leaves, fruit roots and bark all have extensive medicinal value. It is not only suitable for drought, sand wasteland, saline-alkali land planting, but also an excellent tree species in courtyard economy; the fruiting period is long, it can be planted for 50 years in the same year, and it can enter the full fruit period in 3-4 years. Generally, the yield of dried fruit can reach more than 3000 kg per hectare, and its fruit contains a variety of organic compounds and nutrients, which can tonify the kidney, nourish the liver, clear eyes, promote blood circulation, anticancer and so on. Improved varieties were selected for ①. There are many varieties of Chinese wolfberry, nearly 1.

Seedling raising technique of short-spike cutting of Lycium barbarum
Lycium barbarum seedlings raised by short-spike cutting is better than seed propagation, which can not only maintain species character and reduce variation, but also have the advantages of large propagation coefficient, simple operation, high survival rate, quick coming out of nursery and so on. First, the nursery bed preparation for raising seedlings should choose sandy loam with leeward direction and convenient drainage and irrigation. The nursery bed is 1 meter wide and the length depends on the terrain and needs. The nursery bed is covered with 10 cm thick gravel and coarse sand, and the upper bed is covered with a mixture of sifted loess, burnt soil and fine sand, with a proportion of 70%, 20%, 10% and 10 cm thick, respectively.
