Agricultural microbial agent as well as preparation method and application thereof

Abstract

The invention relates to an agricultural microbial agent which is processed from the following raw materials in parts by weight: 80-100 parts of straw powder, 10-20 parts of bioactive sludge, 15-25 parts of dried enzymatic biological residue powder, 5-8 parts of organic bentonite, 3-6 parts of propolis powder and 1-2 parts of functional bacteria. The agricultural microbial agent disclosed by the invention can achieve the effects of increasing organic matters in soil, improving the soil structure, loosening the soil, increasing the porosity, reducing the capacity and promoting microbial viability and development of crop roots. The bioactive sludge is enriched in saccharomycetes and glucan, the glucan serving as a macromolecule has adsorbing and loading effects for adsorbing and loading harmful substances in soil subjected to chemical contamination, a natural colloid balance lost by overload and chemical contamination in the soil is promoted and restored, and the biological activity of the soil is improved. Meanwhile, due to the introduced organic bentonite, the agricultural microbial agent achieves the effects of promoting formation of a soil aggregate structure, improving a pore space in the soil, coordinating a solid-liquid-gas ratio in the soil, promoting release of available nutrients, facilitating growth of the root system and improving stress resistance of crops.

Description

technical field [0001] The invention relates to an agricultural microbial bacterial agent and its preparation method and application, belonging to the field of agricultural biotechnology. Background technique [0002] Soil is the foundation of our human existence. The land we live in today has been severely traumatized, and corresponding measures must be taken to restore the soil, such as arable land, and the emergence of chemical fertilizers has made great contributions to increasing production. However, in recent years, in order to pursue production, blind and excessive The input of chemical fertilizers, ignoring the use of organic fertilizers, led to an increase in input costs, but did not increase yields. Instead, it caused serious damage to the soil, including low organic matter, soil acidification, secondary salinization, and soil compaction. The phenomenon of soil degradation and the serious shortage of soil fertility. Especially the soil environment of the facility...

The land we live in today has been severely traumatized, and corresponding measures must be taken to restore the soil, such as arable land, and the emergence of chemical fertilizers has made great contributions to increasing production. However, in recent years, in order to pursue production, blind and excessive The input of chemical fertilizers, ignoring the use of organic fertilizers, led to an increase in input costs, but did not increase yields. Instead, it caused serious damage to the soil, including low organic matter, soil acidification, secondary salinization, and soil compaction. The phenomenon of soil degradation, the serious shortage of soil fertility

Especially the soil environment of the facility, because the facility has a large amount of evaporation, there is no effective precipitation, and horticultural crops with high economic value are planted in the facility, and the use of chemical fertilizers is greater, so the soil environment in the facility is even worse
