Nuisanceless high-yield cultivation method for isatis roots

Abstract

A nuisanceless high-yield cultivation method for isatis roots comprises reclaiming selected fields with deep soil texture and abundant humus in a mountain area, weeding the ground, ploughing deeply, and sunning upturned soil to cure the soil within July and August in the first year, screening stones and weeds in the soil one week before seeding, covering 20 cm leaf mold on leveled soil, preparing seedbeds and seeding; uniformly spreading seeds on the seedbeds in the early of middle of April, covering 1.5 cm soil, covering straws on the soil, irrigating enough water to wait for germination after 7 days; watering every day in dry seasons, weeding when weeds show up, shading especially in high temperature seasons from June to July; controlling insect deceases; harvesting in sunny days, cutting overground portions of folium isatidis in November in the first year, and drying in the sun after harvesting, grubbing after harvesting the folium isatidis for 10 days using hoes, until reach to bottoms of bulbs to prevent from damaging the bulbs, manually removing basal parts of stems and soil, and drying in the sun.

Description

technical field [0001] The invention relates to the technical field of planting Chinese medicinal materials, in particular to a pollution-free and high-yield planting method of Radix isatidis. Background technique [0002] Radix isatis is very popular as a traditional Chinese medicinal material. There are various planting methods for Radix isatidis, and the existing planting techniques for Radix isatidis all use deep plowing to apply the required base fertilizer into the soil. The amount of fertilization is large and the rainwater loss is serious. , The utilization rate is low, the planting cost is high, and it also causes the pollution of the surrounding water body; in the clay soil area, there is a lot of rain, which is easy to leaching and pollute the surrounding water body; if the flat furrow is made, the rainwater irrigation and drainage will not be smooth, which will easily cause the soil on the furrow surface to harden, which is unfavorable The exhalation of the root ...
