High-efficiency microbial organic fertilizer and preparation method thereof

Abstract

The invention discloses a high-efficiency microbial organic fertilizer. The high-efficiency microbial organic fertilizer is prepared from the following raw materials: filtered mud, rice bran, peanut bran, molasses, yeast waste solution, a compound fermentation strain and compound fermentation enzyme. The invention also discloses a preparation method of the high-efficiency microbial organic fertilizer. The preparation method comprises a multistage fermentation step, an ageing step and the like. According to the high-efficiency microbial organic fertilizer disclosed by the invention, the prematurity of crops can be promoted, and the yield and the quality are improved; in addition, the use amounts of fertilizer and pesticides are reduced, soil is improved and the hazards of heavy metal to the soil and the crops is eliminated.

Description

technical field [0001] The invention relates to the field of pesticides and chemical fertilizers, in particular to a high-efficiency microbial organic fertilizer and a preparation method thereof. Background technique [0002] In modern agriculture, chemical fertilizers and pesticides are indispensable substances, especially China is a large agricultural country with a large amount of planting, so there is a great demand for fertilizers and pesticides. Although it has a certain effect on increasing production and income, long-term use will cause soil acidification and compaction, resulting in poor water retention, fertilizer retention, and air permeability of the soil, and less organic matter; secondly, it will cause excessive accumulation of harmful chemical residues in the soil, and a large amount Heavy metal elements exist in various complex forms, forming flocculents, glue films and other forms that hinder plant growth and wrapping plant roots, making them unable to absor...

Problems solved by technology

Although it has a certain effect on increasing production and income, long-term use will cause soil acidification and compaction, resulting in poor water retention, fertilizer retention, and air permeability of the soil, and less organic matter; secondly, it will cause excessive accumulation of harmful chemical residues in the soil. The heavy metal elements exist in various complex forms, forming flocculents, glue films and other forms that hinder plant growth and wrapping the roots of plants, making them unable to absorb nutrients. In addition, some heavy metal elements in a free state are directly absorbed by plants. Heavy metals in crops seriously exceed the standard, affecting their growth and development

Due to poor air permeability after soil compaction, some fertilizers and pesticides are discharged into rivers and lakes or residual soil and crops, reducing the utilization rate of fertilizers, not only causing waste of resources, but also destroying the agricultural ecological environment and endangering the safety of humans and animals.
