Sugarcane pesticide fertilizer for preventing and treating brown streak disease and preparation method thereof

Abstract

The invention provides a sugarcane pesticide fertilizer for preventing and treating brown streak disease and a preparation method thereof, and relates to the field of fertilizers. The sugarcane pesticide fertilizer for preventing and treating brown streak disease is prepared from the following raw materials in parts by weight: 600 to 650 parts of antibacterial bacteria liquid, 675 to 725 parts of phosphorus-accumulating bacteria liquid, 675 to 725 parts of potassium bacteria liquid, 4 to 6 parts of ammonium sulfate, 2 to 4 parts of potassium sulfate, 3 to 5 parts of molasses, 6 to 8 parts of glucose, 1 to 3 parts of radix astragali seu hedysari extract, 9 to 12 parts of light calcium carbonate, 0.05 to 0.06 part of hydroxypropyl methyl cellulose, 6 to 8 parts of styrylphenol polyoxyethylene ether and 5 to 8 parts of anti-settling agent. 2 to 3 parts of tetrachloroisophthalonitrile and 4 to 6 parts of organic silicon. According to the method, bacillus subtilis is cultured, screened and propagated to obtain an anti-pathogenic bacterium solution, the anti-pathogenic bacterium solution is matched with tetrachloroisophthalonitrile to inhibit bacteria including pathogenic bacteria of sugarcane brown streak, and the pesticide fertilizer has the effect of slowly releasing phosphate fertilizer and potash fertilizer, so that the disease resistance of sugarcane is improved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a sugarcane medicinal fertilizer for preventing and treating brown streak disease and a preparation method thereof. Background technique [0002] During the growth of sugarcane, the demand for nitrogen, phosphorus and potassium is relatively high. In the absence of phosphorus and potassium, sugarcane has insufficient disease resistance and is easily infected by conidia of fungal diseases and suffers from brown streak disease. Harmful, water-soaked yellow-brown striped lesions will appear on sugarcane leaves, and harmful pathogens can be inhibited by spraying fertilizers. [0003] Medicated fertilizers are compound fertilizers made of fertilizers as carriers of pesticides. Existing sugarcane medicated fertilizers have insufficient inhibitory ability to sugarcane brown streak pathogens, and medicated fertilizers are difficult to significantly improve the ability of sugarcane to resist pa...
