Problems solved by technology

Due to the diversity and synchronous evolution of pathogenic bacteria, the single antagonistic strain used cannot achieve a very ideal control effect. Therefore, many biological functions of bio-control bacteria need to rely on the synergy between two or more strains of bacteria to exert better effect

Abstract

The invention provides a compound microbial agent for preventing and treating crop scab and a preparation method and a use method thereof. The compound microbial agent is high in pertinence to crop bacterial scab, the mutual synergistic effect of microorganisms is reasonably utilized, the rhizosphere ecological environment of crops is improved through life activities of active microorganisms contained in the microbial agent, and nutrient elements which cannot be directly utilized by crops in the soil are converted into available quick-acting nutrients for the crops. In the aspect of disease treatment, the microbial agent adopts the principle of treating bacteria with bacteria, and the growth of pathogenic bacteria in soil is inhibited by using antibiotic substances secreted by antagonistic strains, so that the pathogenic bacteria cannot reach the pathogenic quantity in the soil, and cannot infect crops. Thecompound microbial agent prevents the crops from attacking diseases, and is strong in adaptability and good in stability. The compound microbial agent can efficiently antagonize potato scab, tomato pepper scab and winter jujube scab, effectively reduce pesticide residue, cannot pollute the environment, and has the effects of fixing nitrogen, dissolving phosphorus and potassium, stimulating plant growth, improving crop quality and the like, so that the purposes of increasing yield and producing high yield are achieved.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a compound microbial agent for preventing and treating crop scab and methods for making and using the same. Background technique [0002] Scab disease, English: scab (the knot on the wound or sore); (plant) spot disease. Scab is a common disease in crop cultivation. It is divided into bacterial type and fungal type. The bacterial type is mainly caused by Streptomyces (Streptomyces) and Xanthomonas (Xanthomonas) in actinomycetes; fungi are mainly caused by scab. Caused by Elsinoe and S-phaceloma. At present, most of the scabs on crops in China are treated with chemical pesticides. The abuse of pesticides has caused very serious environmental problems, causing the bacteria to develop drug resistance. In addition, the excessive use of chemical fertilizers has aggravated the compaction and pollution of the soil, resulting in soil pollution. The decline and...
