Cotton blight and verticillium wilt preventing soil repair agent and preparation thereof

Abstract

The invention relates to the technical field of pesticides, which relates to a cotton blight and verticillium wilt resistance earth restoration agent, and a preparation method and a use method thereof; the raw material weight portions of the cotton verticillium wilt resistance earth restoration agent are as follows: 50 to 200 portions of yellow humic acid, 50 to 150 portions of humic acid ammonium, 50 to 200 portions of humic acid kalium, 2 to 10 portions of fenaminosulf, 10 to 20 portions of carbendazim, 20 to 50 portions of trace element, 100 to 200 portions of concentrated superphosphate, 50 to 200 portions of urea and 100 to 200 portions of betonite. The invention can improve the resistibility and immunity of the cotton, degrade, complex and eliminate hazardous materials, provide sufficient nutritious ingredients, adjust the physiological function of the cotton and also restrain the pathogen spore growth of the blight and verticillium wilt of the cotton to enhance the resistibility of the cotton so as to effectively restrain the blight and verticillium wilt of the cotton, in addition to the functions of effectively improving the earth structure, increasing the earth organic matter content, accelerating the activation of the nutrient element in the earth and restraining the earth degeneration.

Description

technical field [0001] The invention relates to the technical field of pesticides, and relates to a soil repair agent for resisting cotton fusarium wilt and its preparation method and application method. Background technique [0002] According to the data, the pollution of farmland by three wastes, air, and chemicals tends to intensify, and the problems of soil desertification and salinization are also quite serious. Unreasonable application of chemical fertilizers accelerates the consumption of organic matter and causes some physical properties of the soil such as air permeability. , changes in water holding capacity, arableness, etc. Long-term application of chemical fertilizers causes changes in soil pH, leading to a certain degree of acidification or alkalization. The most fundamental way to control the negative effects of chemical fertilizers on the agricultural environment is to control the input of chemical fertilizers. Emphasize balanced fertilization techniques, and...
