Example Embodiment

[0013] Example 1:

[0014] The specific steps of this embodiment are as follows:

[0015] ①Site preparation: Choose a flat, well-drained, loose and fertile sandy soil, apply 6000kg of decomposed high-quality farm manure, 200kg of superphosphate and 500kg of plant ash per acre, and evenly sprinkle it in the ground, turning 25-35cm deep to make A border of 1.5~2mm wide and 15~20cm high, and then planting furrows with a depth of 20~30mm at a row spacing of 10~15cm;

[0016] ②Sowing: in late April each year, before sowing, soak the seeds in warm water at 35-45°C for 8-10 hours. When the saturation rate of the seeds reaches 85%, pick up and dry them, and then dry the seeds. Mix and stir evenly with the pre-prepared Chinese herbal medicine insecticide in a ratio of 1:100. The Chinese herbal medicine insecticide is 600-800g of chamaejasme, 450-600g of Stemona, 500-650g of Sophora flavescens and 300- 400g of eucalyptus leaves are placed in 20000~25000g of water, boiled for 1~3 hours, and t...

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.
