When the temperature is above 6℃ in spring, spring buds begin to sprout. Lycium barbarum overwinters at -25℃ without freezing injury. Lycium barbarum has developed root system and strong drought resistance, and can still grow in arid desert. In order to obtain high yield in production, it is still necessary to ensure water supply, especially in the flower and fruit period. The low-lying land with long-term water accumulation is not conducive to the growth of Lycium barbarum, and even causes root rot or death.
With sufficient light, the branches of Lycium barbarum grow healthily, with many flowers and fruits, large fruit grains, high yield and good quality. Lycium barbarum mostly grows in alkaline soil and sandy loam, which is most suitable for cultivation in deep and fertile loam.
Planting method of Lycium barbarum seedlings: selection of nursery land: Lycium barbarum nursery land should be selected on sandy loam with flat terrain. It is necessary to establish a good drainage and irrigation system to facilitate water diversion and irrigation when there is little rain. The groundwater level at the bottom of the temple should be below 1.5m, and the soil salt content should be below 0.2%.
Apply base fertilizer: Lycium barbarum is a plant with high fertilizer tolerance. The growth of Lycium barbarum at seedling stage is directly related to the application of base fertilizer before seedling. Fertilization in nursery is mainly decomposed farmyard manure, supplemented by chemical fertilizer. Pig manure, chicken manure, cow manure and manure can be used as basic application. Diammonium phosphate and potassium sulfate are used as fertilizers. Sprinkle some fertilizer on the nursery before turning the soil. The application amount of farm manure is 2500-4000 kg per mu; The dosage of diammonium phosphate is10 kg; 5 kilograms of potassium sulfate.
Soil preparation and deep ploughing: after applying sufficient base fertilizer. First of all, deep tillage and leveling should be carried out, and the tillage depth should be between 20 and 25 cm, which is beneficial to the growth and development of seedling roots in the future. After turning the soil, it can be properly aired for 2-3 days. Before seedling raising, level the broken soil 1-2 times with a rake. The flatter the better, the finer the soil. Then remove weeds, stones and other debris.
Lycium barbarum, also known as "Hongbao", is famous at home and abroad. Chinese wolfberry is the cold dew of Saibei, which nourishes the essence of heaven and earth. The fresh fruit is delicate and red, and looks like a ruby. Dried fruits are ruddy in color, thin in skin and thick in flesh, and fresh and sweet in seeds. The fruit contains Lycium barbarum polysaccharide, 18 amino acids and various trace elements such as carotene, calcium, iron, phosphorus and lithium.
