Microbial complex bacterial agent and use thereof

Abstract

The invention discloses a microorganism compound microbial inoculum, the strains of which comprise bacillus, soil actinomycetes, microzyme, mildew and photosynthetic bacteria. By using the microbial inoculum for straw fermentation, a result indicates that the microbial inoculum can make straws quickly decay and transfer to organic fertilizer required for the growth of plants, thereby the content of soil humus is increased, and the content of microorganism and trace elements in soil is improved. The physicochemical property of soil is improved, and the capability of water and fertility preserving of soil is increased. The soil permeability can also be improved so as to inhibit the happening of crop pests, and the output and quality of products can be improved. The microbial inoculum has the advantages of convenient use, low cost and obvious effect.

Description

Technical field [0001] The invention relates to a microbial composite bacterial agent and its application. Background technique [0002] Straw is a general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, oilseeds, cotton, sugar cane or other crops after harvesting their seeds. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource. [0003] my country has a long history of using crop stalks, but due to the low level of agricultural production and low crop yields, the amount of stalks is small. Except for a small amount of stalks used for gaskets, feeding livestock, and partly used for composting, most of the stalks are burned as life fuel. Up. With the development of agricultural production in China, since the 1980s, food production has increased sub...

Burning straw in farmland will not only destroy the soil, waste resources, but also pollute the environment

The unburned straw is piled up because it cannot be returned to the field in time, which will also cause environmental pollution and reduce the organic matter content of the soil due to the ineffective return of straw to the field.

In recent years, with the widespread use of chemical fertilizers, the output of planting has greatly increased, but the continuous use of chemical fertilizers for many years has also brought serious side effects to the soil: due to the decrease in soil organic matter content, the micro-ecological balance of the soil is destroyed, and the composition ratio is serious. Imbalance; soil hardening and hardening, soil fertility degrades year by year, and the ability to retain fertilizer and water is greatly reduced; soil-borne diseases intensify, increase the amount of pesticides, and increase the cost of agricultural input; the quality of crops is greatly reduced; the agricultural ecological environment is destroyed, resulting in harmful Residues exceed the standard, seriously endangering human health
