Spring cutting method of Lycium barbarum
First, thinning branches. First of all, the dead branches, disease and insect branches, injured branches, acupuncture branches and cross-cutting branches should be cut off, and then the fruit branches that are too dense should be cut. When thinning fruit branches, first remove shade branches, lower back branches, thin and weak branches; then remove upper branches and middle branches; if it is still dense, then sparse both sides of the branches, and after pruning, the distance between fruit branches is 5-6 cm, and they are all white branches with full growth and strong fruiting power.
Second, deal with the growing branches. The elongated branches growing at the droop of the backbone branches are reserved as the elongated branches of the backbone branches, and cut properly to stabilize the branch potential and extension direction; if there is space near the elongated branches, properly truncated, they are cultivated into fruiting branch groups, expanding the crown and increasing the fruiting area; useless elongated branches are cut off from the base.
Third, renew the group of rejuvenated fruit branches. The fruiting branch group of Lycium barbarum was bent and drooping after fruiting for 2 years, and the fruiting ability decreased. For this fruiting branch group, 3-5 cm was left short. After sprouting in spring, a bud with suitable growth direction and strong position was selected and cultivated into a new fruiting branch group by coring.
Fourth, renew the fruit branches of culture. The fruiting ability of Chinese wolfberry fruit branches varies with different varieties, some can bear two consecutive seasons of fruit, some can only bear one season of fruit, or only bear small and few fruits at the top. As a result, the weak fruit branches are characterized by grayish brown branches and obvious very short branches. This kind of fruit branch must be truncated and updated in time. Generally cut from the bent and drooping part of the fruit branch, the sturdy short cut 1max 2, the weak short cut 2pm 3, the weak one only 5-6cm short, and the short cut degree would rather be light than heavy.

Winter pruning of Chinese wolfberry
After a year of growth, the Chinese wolfberry tree has many branches and a messy crown, and at the same time when new fruit branches are formed, some fruit branches have begun to grow old. Therefore, Chinese wolfberry needs to be pruned in winter, otherwise it will affect the yield and quality of the following year. By pruning, removing the old and replacing the new, selecting the old eye branches and seven inch branches with strong fruiting power, and cutting off the non-productive branches, it can lay a good foundation for the old eye branches to bear fruit and grow new fruit branches in the next year. In order to manage conveniently, it is necessary to control the height of the tree by cutting the top.

Harvest and Storage of Lycium barbarum L.
1. Harvest of wolfberry. The fruit of medicinal wolfberry ripens from June to November every year and should be picked in due time. When the fruit from green to red or orange, fruit stalk, flesh slightly soft can be picked. Picked too early, the fruit is not full, the color is not fresh after drying; picked too late, the sugar is too sufficient and easy to fall off, dried or dried into dark red (commonly known as oilseeds) and reduce the commodity value. Fruit picking should be carried out after 10:00 a.m. on sunny days. Do not pick rain consequences and dew fruits. Take them gently when picking, and pick them together with fruit stems. Otherwise, juice outflow will affect
