Abstract

The invention relates to a method for using plant straw to prepare plant disease bactericide, which uses corn straw and wheat straw as materials to be broken, mixed, disinfected, fermented two times and two same hydrolysis to obtain composite humic acid to be purified, disinfected, and degraded in acid, to obtain the inventive product, which contains high-content xanthohumol and various amino acids and nucleic acids with high nutrient content, disease prevention and high leakage function to improve the permeability and activity of cell, while it can prevent plant disease.

Description

technical field [0001] The invention relates to a method for preparing a fungicide for preventing and controlling plant diseases by utilizing crop straws. technical background [0002] At present, the vast number of rural crop stalks are piled up as waste, causing environmental pollution, while the production of fulvic acid from ores is complex, costly, and has a single beneficial component. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing a low-cost, high-efficiency, wide-used biological fungicide that can prevent and control plant diseases by using crop straws. [0004] The present invention adopts following technical scheme: the present invention comprises the following steps: [0005] (1) Preparation of stock solution: [0006] a. Straw crushing: take more than two kinds of corn straw, wheat straw, rice straw and cotton straw to crush, the fineness requirement is 20-30 mesh, and the wa...
