Preparation method of anti-disease medicine against potato bacterial wilt

Abstract

The invention discloses a preparation method of an anti-disease medicine against potato bacterial wilt, which comprises the following steps: (A) material preparation: preparing streptomycin sulfate, 25% cuaminosulfate aqueous solution, 2% formalin, glycyrrhizic acid, chlorogenic acid, polyoxin, radix ampelopsis and dried orange peel; (B) alcohol digestion of the extraction liquid of radix ampelopsis and dried orange peel: crushing the radix ampelopsis and dried orange peel, washing and airing; putting into a closed container, adding 70% ethanol solution by mass, and soaking for 12 hours; putting into a percolator, wherein the percolator is of a bucket structure with a cone at the bottom, the cone is downward connected with equipment which can be opened / closed to drop water, and the percolator is used for extracting the components of the medicinal materials; uniformly putting the medicinal materials into the bucket, and adding the soaking liquid water or wine slowly and dropwise; collecting the percolation liquid; and heating to recover ethanol to obtain the extraction liquid; and (C) compounding the streptomycin sulfate, 25% cuaminosulfate aqueous solution, 2% formalin, glycyrrhizic acid, chlorogenic acid and polyoxin with the extraction liquid obtained by the step (B), stirring uniformly and performing ultraviolet sterilization to obtain the anti-disease medicine against potato bacterial wilt. The preparation method disclosed by the invention is simple, and the prepared product is simple in formula and convenient to use and realizes a good effect in treating the potato bacterial wilt.

Description

[0001] Technical field: [0002] The invention relates to vegetable medicines, in particular to a method for manufacturing potato bacterial wilt disease-resistant medicines. [0003] Background technique: [0004] Bacterial wilt is the main disease of potato. The main symptom is that the plants wilt and die quickly, and the stems and leaves remain green. The browning part of the diseased stem is squeezed by hand, and milky white bacteria liquid is discharged. The disease is prone to occur under the conditions of high temperature and high humidity, continuous cropping, low-lying soil, water accumulation in the field, acidic soil, and partial application of nitrogen fertilizers. Ralstonia solanacearum can enter the soil together with diseased plant residues. Long-term survival forms a source of infection. Soil moisture has a great influence on its survival in the soil. In alluvial soil with high humidity, it can survive for up to 2 to 3 years, but in dry soil, it can onl...
