Abstract

The invention provides a biological control composite microbial agent. The biological control composite microbial agent is prepared by the following steps of: fermenting biological control bacillus subtilis HL259, bacillus mucilaginosus Krassilnikov and biological control streptomyces sp. YL04 strains respectively; adsorbing the materials by using an adsorbing medium; and mixing the materials according to the mass ratio of the fermenting biological control bacillus subtilis HL259 to the bacillus mucilaginosus Krassilnikov to the biological control streptomyces sp. YL04 of 4-5:2.5-3.5:1-2. Theinvention also provides a composite microbial fertilizer produced by using the microbial agent and hydrolytic slag and a production method thereof. The biological control composite microbial fertilizer can effectively improve manurial effect, has obvious effect of preventing and controlling diseases of crops, greatly reduces seedling disease rate, comprehensively provides nutrients required by growth of the crops and increases yield of the crops.

Description

technical field

[0001] The invention relates to a compound microbial fertilizer and a production method of the compound microbial fertilizer, in particular to a compound microbial fertilizer with biocontrol effect and a production method of the fertilizer. Background technique

[0002] Insect pests and diseases of crops are always important factors affecting their yields. The occurrence of pests and diseases can seriously reduce crop yields, or even fail them. Therefore, effective control of pests and diseases is very important. For a long time, my country's agriculture has mainly used chemical pesticides and chemical fungicides to prevent and control pests and diseases. In the past 20 years, the application of chemical pesticides has played an important role in ensuring the safe production of my country's agriculture, but this has led to anti-adjustment and intensive farming. Long-term over-reliance on chemical fertilizers and pesticides has resulted in the waste of a large ...
