Problems solved by technology

[0004] The residues of agricultural product processing, such as peanut dry, molasses, soybean cake and other materials are generally difficult to continue to use in agriculture, causing a large amount of nutrient resources to be lost outside the soil-soil system, which greatly wastes energy as organic fertilizers and biological resources. The organic resources of organic fertilizer production raw materials are not conducive to the sustainable development of my country's agriculture

Abstract

The invention discloses a bio-organic fertilizer for preventing and treating soil-borne diseases. The bio-organic fertilizer is prepared from the following raw materials: a microbial inoculum, peanutoil pressing residues, corn starch, filter mud, beef extract, soybean cake, monopotassium phosphate, urea, molasses, potassium sulfate, water and the like. The microbial inoculum is composed of Bacillus polymyxa and further comprises any one or a mixture of more than one of Bacillus amyloliquefaciens, Bacillus mucilaginosus and Bacillus pumilus. The invention also provides a preparation method andan application method of the bio-organic fertilizer. The bio-organic fertilizer disclosed by the invention is also rich in organic carbon and organic nitrogen, so that the colonization and function exerting capabilities of functional microorganisms in soil are improved, the growth of pathogenic microorganisms is favorably inhibited, and soil-borne diseases such as root rot, bacterial wilt, seedling blight, damping-off, canker and root-knot nematode disease are effectively prevented. The use amount of chemical fertilizers and pesticides can be reduced, guiding significance is provided for production of harmless agricultural products, and good social benefits and economic benefits are achieved.

Description

technical field [0001] The invention relates to a bio-organic fertilizer for preventing and controlling soil-borne diseases, a preparation method and application thereof. Background technique [0002] Soil-borne diseases refer to diseases caused by pathogens such as fungi, bacteria, nematodes and viruses that live in the soil with diseased residues and attack crops from roots or stems when conditions are suitable. Infection pathogens include fungi, bacteria, actinomycetes, and nematodes. Among them, fungi are mainly divided into non-obligate parasitism and obligate parasitism. Non-obligate parasitism is an ectophytic root-infecting fungus, such as Pythium spp. causing seedling rot and damping-off, and Rhizoctonia causing seedling blight. Obligate parasitism is the original fungus of plant microtubule disease soil-borne disease, typical wilting and death caused by Fusarium oxysporum and Verticillium alboatum. The severity of root disease is controlled by the composition an...
