Key points of new techniques for cutting seedlings of Lycium barbarum

Lycium barbarum is a perennial deciduous shrub of Solanaceae, about 2 meters high, with angled and spiny branches; simple leaves alternate or clustered on short branches, lanceolate or rhombic, entire; flowers purplish red; berries, orange-red, ovate or long oval. Chinese wolfberry like cold, cool and humid fertile soil, cold-resistant, drought-resistant, wind and rain-resistant, but not resistant to high temperature, and can grow normally in barren roads, ditches and canals.

Lycium barbarum can be propagated by seeds, and can also be propagated by rafts, strips and cuttings. now it is mainly described that the method of raising seedlings by cutting in facilities: 1. Soil preparation: 5000 kg of soil miscellaneous fertilizer, 100kg of three-element compound fertilizer or 150kg of compound fertilizer are applied in combination with soil preparation. It is required that the tillage depth is more than 30cm, the soil is raked up, the soil is leveled, and the fertilizer is mixed evenly, and then make a flat bed 1 meter wide, with the north-south border as good. 2. Cutting cuttings: in late February, one-year-old branches with full development and free of diseases and insect pests were cut from Chinese wolfberry trees and cut into cuttings with a length of 15 cm. The upper mouth should be flat and the lower cut mouth was oblique, with a bundle of 100 cuttings, stored in sand in the house and kept at about 5 ℃ at room temperature. 3. Buckle film: in early March, choose a sunny and windless day, cover the plastic film on the shed to bake the ground, and raise the temperature of the shed. 4. Management of cuttings: in late March, the cuttings were taken out and soaked in running water for one day and night, then directly or obliquely inserted on the border in the shed, requiring about 10 cm of soil, 5 rows per row, plant spacing of 10 cm × 20 cm, and watered thoroughly after planting. Through measures such as uncovering, covering cloth and releasing air, the temperature of the greenhouse is controlled above 12 ℃, the surface is moist, and can germinate in about 25 days. After germination, the temperature of the greenhouse is controlled above 10 ℃, and the surface is slightly wet (or 75% relative humidity). When grass grows on the border, shallow and medium ploughing can be used to weed and raise the ground temperature. In the middle of April, after a period of time, you can go to the greenhouse film, if you have insects, you can use 3000 times the enemy to kill and control, other management is the same as on land.
