Method for manufacturing quinclorac solid degrading inoculant

Abstract

The invention provides a method for manufacturing a quinclorac solid degrading inoculant, and belongs to the technical field of microorganisms. The method includes the steps that 1, preparation, pH adjustment and sterilization of a medium are conducted; 2, bordetella preserved on a bevel is inoculated, and shake cultivation is carried out to obtain liquid seeds; 3, the liquid seeds are inoculated in a culture medium containing wheat bran, corn straw powder and activated carbon, and are cultured in a constant-temperature culture box in a sealed mode to obtain a target product. The organophosphorus pesticide degrading inoculant produced through the technology has the advantages of being low in product cost and environmentally friendly, and the inoculant can efficiently degrade organophosphorus pesticide residues on the surfaces of plants and in soil. Besides, physical and chemical properties and biological characters of the soil can be improved, soil fertility is improved, immunity of crops can be enhanced, intrusion of bacteria is prevented, and the inoculant particularly has a good prevention function on soil-borne diseases and the continuous cropping barrier. Thus, crop growth is promoted, the agricultural yield is increased, quality of agricultural products is improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a preparation method of a quinclorac solid-state degrading bacterial agent. Background technique [0002] Quinclorac is a hormone-type quinolinic acid herbicide with strong selectivity. It is a new type of hormone-type quinoline carboxylic acid herbicide developed by BASF in the early 1980s, mainly used for preventing barnyardgrass in paddy fields. The application of quinclorac in paddy fields also caused certain harm to the subsequent tobacco fields, causing deformed growth of tobacco plants, shortening of plants, curling of the back of new leaves, shrinkage, and severe suppression of leaf width. Pesticides, as synthetic xenobiotic substances, are usually not easily degraded by microorganisms and have a very long half-life in nature, so they are called recalcitrant compounds. But after long-term natural selection, there are already many microorganisms that can degrad...
