Cultivation method of northern Lycium chinense

Abstract

The invention belongs to a cultivation method of fruit trees, and particularly relates to a cultivation method of northern Lycium chinense. The cultivation method solves the defect that the resource amount of northern Lycium chinense in Gansu Province is sharply reduced since the traditional northern Lycium chinense is influenced by altitude and excessively harvested in recent years, and chemical grass killers are popularized. The cultivation method is characterized in that the pH (potential of Hydrogen) value of sandy soil in a planting land is 7.5.to 8.5; and the land is deeply tilled, prepared and irrigated with winter water in late autumn and early winter of the previous year before sowing, and seeds are sown when the soil is unfrozen in spring of the next year. The cultivation method has the beneficial effects that selected soil is suitable for the growth of Lycium chinense, and scarifying treatment is performed on the seeds before sowing, so that the germination rate of the seeds is greatly increased, the yield of Lycium chinense is increased, the cold resistance and drought resistance of the seeds are improved, the using amounts of agricultural chemicals and chemical fertilizers are reduced, and the quality of Lycium chinense is improved; and the cultivation method is little in planting investment and high in benefit, can bring considerable social and economical benefits, and also can generate great ecological environment benefit.

Description

technical field [0001] The invention belongs to a method for cultivating fruit trees, in particular to a method for cultivating northern wolfberry. Background technique [0002] Northern wolfberry is a perennial deciduous shrub belonging to the family Solanaceae Lycium barbarum. It is a nutritious fruit containing betaine, polysaccharides, crude fat, crude protein, carotene, vitamin A, vitamin C, vitamin B1, vitamin B2 and calcium, phosphorus, Nutrients such as iron, zinc, manganese, and linoleic acid can promote hematopoietic function, and can also be anti-aging, anti-mutation, anti-tumor, anti-fatty liver, and hypoglycemic. Lycium barbarum is a precious medicinal material and tonic. Traditional Chinese medicine has long said that "wolfberry preserves health". Its production areas are mainly concentrated in the northwest region, and the goji berries in Ningxia are the most famous. In addition, the goji berries in Gansu, Qinghai and other places are also of high quality. ...

AI Technical Summary

Problems solved by technology

From the perspective of the main distribution area, it can be cultivated in places with an average annual temperature of 5.6-12.6°C. The root system of wolfberry is well developed, and there are two growth periods a year, followed by two flowering and fruiting periods. In late June and autumn buds in early September, the seedlings can bloom and bear fruit that year. Later, with the growth of tree age, the ability to flower and bear fruit will gradually increase, and the economic age is about 30 years; the seeds of wolfberry are very small, and the dry weight is only 0.83-1.0g , under conventional storage conditions, the seed life is 4 to 5 years, and the optimum temperature for germination is 20 to 25 °C, but the germination rate of Lycium barbarum seeds in Gansu is low, and it is affected by the altitude and the over-harvesting and chemical herbicides in recent years. Popularization has caused a sharp decrease in the resources of wolfberry in the north of Gansu Province. A kind of wolfberry seed germination measure and its cultivation method are needed. Increased yield and good quality
