Problems solved by technology

However, kudzu vine reproduces very quickly, and in forest areas, it often wraps and covers trees due to crazy growth, causing the trees to fail to grow normally or even die
Pueraria contains a large amount of alkali-based active materials, which can strongly inhibit the germination of grass seeds; however, this active material is easily polluted by external bacteria, light, oxygen, etc., so that it loses its weeding effect. At the same time, these active materials are not easy to use directly, which brings difficulties to large-scale promotion

Abstract

The invention discloses a preparation method of a high-performance persistent biological herbicide, comprising the following steps: pulverizing the dried kudzu vine to obtain kudzu powder, uniformly mixing the kudzu vine and water to obtain a mixed material, adjusting the pH value of the mixed material, and then adding a compound enzyme preparation , stirred evenly, concentrated after standing to obtain a concentrated mixture; continue to add acetone aqueous solution, after ultrasonic treatment, filter, wash, and concentrate to obtain a kudzu solution; pour the kudzu solution into a resin separation column, after standing, add distilled water and two Liquid material A, liquid material B, and liquid material C are obtained from acetone aqueous solutions of different concentrations; after mixing the above three liquid materials evenly, they are concentrated and dried to obtain the kudzu active material; the kudzu active material and soybean oil are mixed evenly and then subjected to ultrasonic treatment to obtain The kudzu active material solution: adding the kudzu active material solution into the wall material solution for homogenization, spray drying, and cooling to obtain a high-performance persistent biological herbicide.

Description

technical field [0001] The invention relates to the technical field of herbicide preparation, in particular to a preparation method of a high-performance persistent biological herbicide. Background technique [0002] In order to reduce the dependence on chemical herbicides, people have extracted active substances that can inhibit the growth and development of grasses from some plants, and the biological herbicides made have the characteristics of environmental protection and good performance; kudzu vine is one of them. Pueraria vine can grow up to tens of meters or even hundreds of meters, and its leaves are alternate, and the length can reach 40-50cm. Pueraria has both edible and medicinal value. The root of Pueraria is deeply loved by the common people because it is rich in amino acids, isoflavones, puerarin and other nutrients, and has the functions of lowering blood pressure, lowering blood lipids, clearing fire and detoxifying. However, kudzu vine reproduces very quick...
