Problems solved by technology

Because Radix isatidis is vulnerable to downy mildew, powdery mildew, cabbage caterpillar and bud worm during the growth and development process, growers generally use a large amount of organophosphorus insecticides in order to prevent and control pests and diseases and increase profits , these chemical pesticides will not only cause environmental pollution and water quality deterioration, but also there are a large amount of pesticide residues in Radix Radix Radix. , affecting the sustainable development of the agricultural economy. In addition, in the process of planting, growers blindly use excessive chemical fertilizers in order to increase production, which seriously affects the quality and quality of Radix Radix, and its efficacy is also reduced.

Abstract

The invention discloses a pollution-free cultivation method for isatis root. The method mainly comprises the steps of soil preparation, sowing, thinning and final singling, growth period management, disease and pest control and harvesting. The method provided by the invention adopts a traditional Chinese medicinal pesticide, so the growth environment of isatis root is purified, diseases and pests of isatis root are effectively prevented and treated, and the problems of high residual of chemical pesticides, high pollution and poor insect-preventing effects in the prior art are overcome. In addition, in the process of planting, a great amount of farmyard manure is used as main fertilizer, so the medicinal properties of isatis root are protected to a greatest extent; the yield and the quality of isatis root are effectively improved; and the harvested isatis root has long, straight, strong and uniform roots. The cultivation method is advanced and reasonable, has strong operability, can be learned and used by all kinds of populations and has good popularizing value.
