Compound microorganism fertilizer and preparation method thereof

Abstract

The present invention discloses a compound microorganism fertilizer and a preparation method thereof, wherein protease is adopted as a main bacterial agent and animal residue bodies or byproducts are adopted as a carrier to carry out rapid fermentation, three-stage bacterial preparation is performed, a mother fertilizer is prepared from barley powder, cake, blood powder, fish byproducts, glucose and urea, and an Aitian 1# organic fertilizer, a PK bacterial fertilizer, a 5406 bacterial fertilizer and inorganic medium-trace elements are added to prepare the solid powdery fertilizer, the granular finished product fertilizer and the liquid fertilizer. According to the present invention, the raw material sources of the product are wide, the price is low, the production process is simple, the green organic food can be produced, the fertilizer is suitable for various soils, and the application method is simple.

Description

Technical field [0001] The present invention is an agricultural fertilizer technology field, which involves a composite microbial fertilizer and its preparation methods. Background technique [0002] At present, in order to pursue yield in the field of agricultural planting, it has blindly abused chemical fertilizer in the years, which has led to changes in the viciousness of the physical and chemical properties of farmland, serious pollution of groundwater sources, and damage to the ecological environment of the land. [0003] With the large amount of chemical fertilizers, its utilization rate has been decreased is a well -known fact.This shows that it is limited to increase the production of crops alone by adding a large amount of fertilizer, let alone a series of problems such as pollution environment.To this end, scientists in various countries have been working hard to explore the use of chemical fertilizer utilization to balance fertilization and reasonable fertilization to...
