Special disinsection and sterilization polyelement microorganism fertilizer for preventing cabbage downy mildew

Abstract

The invention discloses a special disinsection and sterilization polyelement microorganism fertilizer for preventing cabbage downy mildew. The special disinsection and sterilization polyelement microorganism fertilizer comprises components of raw materials in parts by weight as follows: 3-5 parts of bacillus subtilis, 1-4 parts of trichoderma reesei, 4-8 parts of a fertilizer leavening agent, 1000-1100 parts of an organic fertilizer, 350-500 parts of an inorganic fertilizer, 65-85 parts of a trace element, 5-7 parts of a plant growth regulator, 25-35 parts of an adhesion agent, Chinese herbal medicinal ingredients and the like. The special disinsection and sterilization polyelement microorganism fertilizer for preventing the cabbage downy mildew can reduce the morbidity of the cabbage downy mildew greatly, and reduce bacterial and fungal diseases of leaves of a plant obviously, the plant can grow more vigorously, the yield of cabbages isincreased greatly, the quality is improved, and probiotics in the soil are also increased.

Description

technical field [0001] The invention relates to an insecticidal and bactericidal multi-microbial fertilizer, in particular to a special insecticidal and bactericidal multi-microbial fertilizer for preventing and treating cabbage downy mildew and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Cabbage downy mildew is a worldwide disease caused by the obligate parasitic downy mildew. This fungal disease often causes seedlings to wither and yellow, resulting in reduced yield and quality, causing great losses to cabbage. At present, there are no ideal medicaments and disease-resistant varieties for the prevention and treatment of the disease, and chemical pesticides are the main means of prevention and control. However, the long-term and large-scale application of pesticides not only affects the quality of cabbage, but also makes the bacteria resistant to pesticides, and easily leads to environmental pollution, which s...
