Method of pollution-free planting of isatis tinctoria

Abstract

The invention discloses a method of pollution-free planting of isatis tinctoria. The method is characterized by comprising the following steps of 1, low-temperature storage, wherein isatis tinctoria seeds are firstly subjected to sterilization treatment and are then mixed with organic matter fertilizer for low-temperature storage; 2, seed germination accelerating, wherein the stored seeds are soaked into plant nutrient liquid to be subjected to poikilothermic treatment, and high-temperature storage and low-temperature storage are repeatedly conducted for 5-6 times; 3, soil treatment, wherein the organic matter fertilizer is splashed to soil in early March, then the soil is subjected to deep plowing and airing, an abamectin solution is sprayed to the soil, lime powder is applied to the soil, then the soil is covered with transparent mulching film, then the nutrient sterilization liquid is utilized for spraying, and finally the treated soil is subjected to bed preparing; 4, planting, wherein the seeds after subjected to germination accelerating are sowed to beds in late March to early April and are covered with mulching film, and the mulching film at the upper portion of planting pits are left with breather holes; 5, daily management, wherein the plant nutrient liquid is periodically utilized for watering, the plant sterilization liquid is utilized for spraying, and the organic matter fertilizer is utilized to topdress isatis tinctoria in July and September.

Description

Problems solved by technology

[0003] The present invention aims at the existing problems: adopting the sowing method, the seed skin is thin and the matrix is ​​small, the seed germination speed is slow after direct sowing, and mildew and deterioration will occur in the soil buried for a long time, resulting in low germination rate, and the cultivated seedlings grow slowly , Poor resistance to diseases and insect pests; Isatis indigo is vulnerable to downy mildew, sclerotinia, root rot and diamondback moth during growth. There are many types of diseases and high pest and disease rates. It is very difficult, and it will cause pesticide residues in the medicinal roots and leaves, which will pollute the medicine; while the roots of Isatis indigo are prone to forks during the growth process, and the planted roots have many and short forks, and the appearance quality of the medicinal materials and the active ingredients of the medicine poor content
