Cultivation techniques of Chinese wolfberry

In our country, wolfberry has a long history of homology with medicine and food. It is a famous Chinese herbal medicine. As early as in Shennong Materia Medica, it was listed as top grade, called "long-term service, light body, cold and heat resistance"; it has the effect of delaying aging and resisting aging, also known as "Lao Zi". The following small series will explain the cultivation techniques of wolfberry for everyone.

1. Seed reproduction

Select fine varieties, soak and wash with warm water at 30-60℃, and dry for later use. Mix wet sand before sowing, germinate at room temperature of 20℃, and sow when 30% seeds are exposed. mainly spring sowing. According to the row spacing of 40cm, trenching and drilling, depth of 1.5- 3 cm, soil cover 1- 3 cm, after seedlings emerge, according to soil moisture, pay attention to irrigation.

The seedling height is 1.5-3cm, the soil is loosened and weeded once, and then the soil is loosened and weeded once every 20-30 days. The seedling height is 6-9cm, the seedlings are fixed at regular intervals, the plant spacing is 12-15cm, and 150 thousand-180 thousand seedlings are reserved per hm2. In order to ensure the growth of seedlings, the lateral buds growing at 40cm above the ground should be removed in time. When the seedling height is 60cm, the top should be removed to accelerate the growth of trunk and upper lateral branches. When the root thickness is 0.7 cm, it can be transplanted out of the nursery.

2. Field management

Weeding was done once in May, June and July, sheep manure, manure and cake fertilizer were applied as base fertilizer from late October to early November, urea could be applied in May and phosphorus and potassium compound could be applied from June to July. Young trees are shaped, 3-5 strong branches are selected as main branches around the upper part of the trunk in autumn of the year after planting, and are truncated at about 20cm, and when new branches are sent out in spring of the second year, the branches are truncated at 20-25cm as backbone branches. In the 3rd and 4th year, the method of the 2nd year was imitated, and the excessive branches on the main branches were used to enlarge and enrich the crown skeleton.

After 5-6 years of plastic culture into adult tree stage. Adult trees are pruned, dead branches, cross branches and root sprouts are cut every spring, dense branches are removed in summer, excessive branches, diseased branches and needle branches are cut off. Autumn comprehensive pruning, tidying up the crown, select to stay good fruit branches.

4. Principle of pruning

To old and new, to disease and strong, to weak and strong, so that the fruit branches evenly distributed in the crown. It is required to cultivate more fruit branches and cut off non-productive branches.

Lycium barbarum is generally picked when the fruit is ripe in summer and autumn. Remove the fruit stalk, dry it in the shade until the peel wrinkles, and then expose it to dry and hard skin and soft pulp. In case of rainy weather, it can be dried with slow fire.
