Planting of Lycium barbarum

Chinese wolfberry can be eaten directly or used as Chinese wolfberry tea. It is a perennial shrub cash crop that is resistant to drought, barren and salt. So, what is the planting technology of Chinese wolfberry tree?

1. Seed propagation

Select excellent varieties, soak and rinse with 30-60 ℃ warm water and air dry. Mix the wet sand well before sowing, germinate at 20 ℃ at room temperature, and sow when 30% of the seeds are white. Spring sowing is the main method. According to the row spacing 40cm ditching strip sowing, deep 1.5-3cm, covering soil 1-3cm, after the seedlings are unearthed, according to soil moisture, pay attention to irrigation.

Seedling height 1.5-3cm, loosen the soil and weed once, and then loosen the soil and weed once every 20-30 days. The height of seedlings was 6-9cm, the distance between seedlings was 12-15cm, and the number of seedlings per 1hm2 was 150000-180000. Combined with irrigation, topdressing fertilizer for 3 times in May, June and July, in order to ensure seedling growth, the lateral buds of young plants off the ground should be removed in time, and the lateral buds should be removed when the seedling height is 60cm, so as to accelerate the growth of trunk and upper lateral branches. When the root is thick and 0.7cm, it can be transplanted out of the nursery.

2. Field management

Ploughing and weeding once in May, June and July, applying sheep manure, barnyard manure and cake manure as base fertilizer and topdressing urea in May and compound application of phosphorus and potassium from June to July. After the young trees were reshaped, 3-5 sturdy branches were selected as the main branches around the upper part of the trunk in the autumn of that year, and truncated at the left and right side of the 20cm, and the new branches were truncated at 20-25cm in the spring of the second year. In the third and fourth year, following the method of the second year, we will continue to use the overgrown branches on the backbone branches to expand, increase height and enrich the crown skeleton.

3. Pruning principle

Get rid of the old and stay new, sick and healthy, weak and strong, so that the fruiting branches are evenly distributed in the crown. It is required to cultivate more fruiting branches and cut off non-productive branches.

After 5-6 years of plastic training, it entered the adult tree stage. Adult trees are pruned, cutting dead branches, cross branches and root sprouting branches every spring, leaving dense and sparse branches in summer, cutting off long branches, disease and insect branches and needle branches. Comprehensive pruning in autumn, tidying up the crown, and selecting good fruiting branches.

4. Harvest

Chinese wolfberry is generally picked when the fruit is ripe in summer and autumn, remove the stalk, dry it in a cool place until the skin is wrinkled, and then expose to the hard outer skin and soft pulp, which can be dried by light fire in case of overcast and rain.

In addition, Chinese wolfberry can also be used as hedges, stakes and shrubs for soil and water conservation.
