Silkworm excrement and bacillus amyloliquefaciens ZFH-3 containing multifunctional biological fertilizer and application thereof

Abstract

The invention discloses a silkworm excrement and bacillus amyloliquefaciens ZFH-3 containing multifunctional biological fertilizer and an application thereof. The silkworm excrement and bacillus amyloliquefaciens ZFH-3 containing multifunctional biological fertilizer is prepared from raw materials in parts by weight as follows: 25-84.9 parts of silkworm excrement, 10-45 parts of tobacco stems and 0.1-30 parts of a bacillus amyloliquefaciens ZFH-3 microbial agent. The silkworm excrement and bacillus amyloliquefaciens ZFH-3 containing multifunctional biological fertilizer is ecological and safe and can improve the content of organic matters in the soil, loosen the soil, activate the nutrient, increase the use ratio of the soil nutrient, increase soil fertility and beneficial bacteria of the soil, maintain the soil microorganism balance, activate the adversity-resistance system of crops, improve the crop nutrient absorbing ability, reduce and inhibit soil-borne diseases and repel soil insects and nematode, use of chemical fertilizers and pesticide is reduced, and the ecological environment of the soil is improved.

Description

technical field [0001] The invention relates to an agricultural biological fertilizer, in particular to a Bacillus amyloliquefaciens ZFH-3 multifunctional biological fertilizer and its application, belonging to the technical field of biological fertilizers. Background technique [0002] For a long time, excessive application of compound fertilizers and less or no application of organic fertilizers in the agricultural production process in our country have caused many serious problems to the soil. Specifically, there are three main aspects: [0003] 1. Compound fertilizers are mostly acidic, aggravating soil acidification, causing soil compaction, fewer new roots of crops, and poor water and fertilizer absorption. [0004] 2. Compound fertilizer components are chemical substances, which can easily cause imbalance of soil flora, decrease of beneficial bacteria, increase of harmful bacteria, soil-borne diseases are becoming more and more serious, and damage the soil ecological...

AI Technical Summary

Problems solved by technology

[0003] 1. Compound fertilizers are mostly acidic, aggravating soil acidification, causing soil compaction, fewer new roots of crops, and poor water and fertilizer absorption

[0004] 2. Compound fertilizers are composed of chemical substances, which can easily cause imbalance of soil flora, reduce beneficial bacteria, increase harmful bacteria, soil-borne diseases are becoming more and more serious, and destroy the soil ecological environment

[0005] 3. The main components of compound fertilizer are nitrogen, phosphorus and potassium macroelements, lacking organic matter and medium and trace elements. Long-term use will easily cause partial consumption of soil nutrients, and the reduction of soil trace and medium elements will lead to a decrease in crop yield and quality.

[0010] At present, there is no report on the combined application of silkworm excrement and Bacillus amyloliquefaciens ZFH-3. Therefore, providing a multifunctional biological fertilizer containing silkworm excrement and Bacillus amyloliquefaciens ZFH-3 and its application has become a technical problem that needs to be solved urgently in this technical field.
