What are the planting techniques of Sophora flavescens in 2020? What are the prospects? How is the income per mu?

Sophora flavescens is a common traditional Chinese medicine in China. With the increasing market demand, natural Sophora flavescens resources are becoming less and less, and large-scale planting of Sophora flavescens has become a trend. What are the planting techniques of Sophora flavescens in 2020? What's the outlook? What about the yield per acre?

I. Cultivation technology and income per mu of Sophora flavescens

1, planting technology

Selection of land: Sophora flavescens is not strict with soil requirements, but it is best to choose a sandy loam with a soil thickness of more than 50CM, loose and fertile soil and good drainage. Gramineae and potato crops are the best crops for the last crop, and it is not suitable to choose sticky soil, saline-alkali land and poor drainage plots.

Sowing: Spring or autumn sowing can be. Spring sowing should be planted before and after Qingming, when soil moisture is better, conducive to emergence. After autumn sowing, it is necessary to cover the soil, otherwise the soil surface is easy to harden, which is not conducive to spring emergence. Autumn sowing should be early rather than late. After the seeds are mature, they can be sown, so that the seedlings can safely overwinter.

Thinning and supplementary seedlings: after germination of seeds, thinning seedlings shall be carried out when the seedling height is 15~20CM, and 3~4 seedlings shall be reserved for each hole. Found that the lack of plants, in time with the seedlings under the supplementary planting, so that seedlings Qi, seedlings complete.

Cultivate weeding: Sophora flavescens seeds sprout 7~10 days after sowing. Because weeds grow faster, they should be removed in time and loosened properly. Weed every two months thereafter.

Topdressing: topdressing the roots in early May, mainly nitrogen fertilizer, to promote the early nutritional growth of seedlings, and then applying 2000 kg of decomposed human and livestock manure per mu, which is conducive to the cultivation of strong seedlings; topdressing again in early July, mainly phosphorus and potassium fertilizer, 30 kg of diammonium phosphate and 20 kg of potassium sulfate per mu, to promote the accumulation of root nutrients and the differentiation of overwintering buds.

Watering: June and July are the peak periods of water demand, and watering must be carried out in case of drought, which is conducive to the growth of rhizomes. In November, the soil was watered before freezing, which was beneficial to the safe overwintering of Sophora flavescens. 50%~70% soil moisture content is beneficial to the growth of Sophora flavescens and the accumulation of medicinal components.

2. Income from mu

To plant one mu of Sophora flavescens, buy 4000 2-year seedlings, 0.2 yuan per plant, 800 yuan in total, 40 labors per mu of Sophora flavescens (10 labors for planting, 20 labors for weeding and 10 labors for digging in two years), 4000 yuan, 200 yuan for fertilizer, 5000 yuan in total, 3000 mu for planting. After two years, it can be harvested. Each mu of Sophora flavescens can harvest 3000 jin. According to the current market price, 3 yuan per catty, and the output value per mu reaches 9000 yuan.

II. Cultivation prospect of Sophora flavescens in 2020

Sophora flavescens can be planted in spring, summer and autumn, which is very suitable for planting habits, soil and climate conditions in Chongqing, Yunnan, Guizhou, Sichuan, Hunan and Hubei mountainous areas. In recent years, because Sophora flavescens is widely used in the production of biological pesticides, and biological pesticides have no pesticide residues, no teratogenic carcinogenicity, poisoning and other side effects on the human body, ensuring the green pollution-free and pesticide residue-free standards of crops, biological pesticides are more and more widely used in plant protection in recent years. As the main raw material of biopesticide, Sophora flavescens is in increasing demand. Furthermore, recent medical research has found that matrine, the main component of Sophora flavescens, has obvious anti-cancer effects, and has been further developed. Now pharmaceutical enterprises have produced matrine injection, as a new anti-cancer drug with the development of the market, its product production has expanded, the demand for raw materials of sophora flavescens also greatly increased, the market prospect is broad.

Although Sophora flavescens has a good planting prospect, in order to ensure economic benefits, it is recommended that growers grasp the market situation of Sophora flavescens in time to adjust the planting scale and ensure maximum benefits.
