Cultivation techniques of Lycium barbarum sprouts

The tender shoots of Chinese wolfberry are pollution-free and have a unique flavor of high-quality green sprouts. It is not only delicious and nutritious, but also has the special health function of tonifying kidney and nourishing liver, so it is favored by consumers. This paper introduces its simple and easy cultivation techniques for reference.

First, choose the variety. Chinese wolfberry as a suitable variety for vegetables, there are fine-leaf Chinese wolfberry and big-leaf Chinese wolfberry, these two kinds of Chinese wolfberry do not bear fruit.

Second, cultivation techniques. Lycium barbarum likes cold climate. The suitable biological temperature is 20: 25 ℃ during the day, 10 ℃ at night, higher than 30 ℃ and lower than 10 ℃, and the growth is poor. Chinese wolfberry plants with fine leaves or large leaves can be selected for propagation by cuttings. take their sturdy branches and cut a section of 15cm to 20cm as cuttings, which are required to leave 3 or 5 axillary buds on each cutting. the lower end of the cuttings is cut into a wedge and stored in shade under the heat preservation condition of about 15 ℃. Select the land with fertile soil, convenient management and no pollution source, combined with land preparation, apply 5000 kg of high-quality rotten livestock and poultry manure per mu, mix the soil and fertilizer evenly, make a good seedbed and open a good drainage ditch. When cutting, the lower end of the cuttings is obliquely cut into the soil of the seedling bed at an angle of 45 degrees, and the top only shows 1 or 2 nodes on the surface. After insertion, the fine broken fertilizer soil is slightly compacted and watered once, and then a small arch shed is supported by bamboo, covered with a good film to keep warm and wet to promote root sprouting. Generally, about 10 days after cutting, new shoots take root and grow. At this time, 3 to 5 strong shoots were selected for cultivation as sprouts, and the rest were thinned out in time. Then ploughing and loosening soil was carried out to promote branch and bud growth. Combined with mid-ploughing, 15 kg urea per mu was applied with water, and then applied once every half a month.

Third, timely harvest. Generally, 40-50 days after cutting, when the height of the seedling is about 40 cm, it will be harvested in time while the basal leaves are not aging. When harvesting, use a sharp knife to cut from the tender part of the stem, these fresh stem and leaf buds are Lycium barbarum sprouts, which can then be tied into small handfuls and listed on the market. In the harvest, it is also possible to cut long and stay short and remove dense slender branches or long branches, and the short side buds left behind can grow into buds of more than 30 cm, and be harvested again when they are young. Generally, it can be harvested every 20 days, and it must be fertilized and watered after each harvest to promote the growth of the next crop of shoots.
