A kind of compound microbial special fertilizer for preventing and treating yam anthracnose and preparation method thereof

Abstract

The invention discloses a special compound microorganism fertilizer for preventing yam anthracnose and a preparation method of the special compound microorganism fertilizer. The special compound microorganism fertilizer for preventing the yam anthracnose comprises components in parts by weight as follows: 2-4 parts of bacillus subtilis, 1-3 parts of frankia, 3-5 parts of streptomycete, 2-4 parts of nystatin, 50-60 parts of urea, 25-30 parts of ammonium phosphate, 15-20 parts of borax, 10-15 parts of ferrous sulfate, 8-10 parts of manganese sulfate, 10-12 parts of zinc sulfate, 20-24 parts of calcium superphosphate, 80-100 parts of peanut cakes, 70-80 parts of a soybean meal, 100-120 parts of maize straw, 90-100 parts of expansion chicken manure, 40-50 parts of waste of a chicken slaughter house, 0.2-0.4 part of multi-effect triazole and 0.4-0.6 part of gibberellin. The special compound microorganism fertilizer can reduce the morbidity of the anthracnose, increase the yield of yams, and improve the soil condition.

Description

technical field [0001] The invention relates to a compound microbial fertilizer, in particular to a special compound microbial fertilizer for preventing and treating yam anthracnose and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Plant soil-borne diseases caused by pathogenic organisms such as bacteria, fungi, and nematodes are an important class of plant diseases. With the help of soil protection, pathogenic organisms can survive in the soil for a long time, and once the host appears, they will be infected in large numbers and cause serious losses. . Yam is a kind of vegetable that we often eat, and it is also a commonly used medicinal material. It is of great value to people. Ma yam is a kind of yam. During the planting process, anthracnose is a fungus that seriously affects its yield and quality. Disease, in the early stage of the disease, brown sunken irregular small spots are produced on the leaves of yam...

Problems solved by technology

However, this method uses a large amount of pesticides and fungicides, some of which are absorbed by the yam body, which will cause harm to the human body, and vegetable farmers generally use conventional chemical fertilizers in the fertilization process, and long-term use will have certain effects on the soil and plants. At present, there is no report on the research on the use of compound organic fertilizers to prevent anthracnose of Chinese yam
