Composite microbial inoculum fertilizer

Abstract

The invention discloses a composite microbial inoculum fertilizer. The invention is characterized in that the fertilizer is prepared from the following components in parts by weight: 6-8 parts of composite microbial inoculum, 25-35 parts of potassium sulfate, 40-55 parts of urea, 35-50 parts of calcium superphosphate, 150-175 parts of biomass power plant ash, 300-330 parts of sawdust, 200-250 parts of biological carbon, 100-115 parts of medical stone powder, 120-125 parts of zeolite powder and 7-9 parts of soil conditioner. The effective components of the composite microbial inoculum comprise Bacillus licheniformis, Bacillus pumilus, Bacillus lateraporus, Bacillus megaterium and silicate bacterium. The composite microbial inoculum is added to the product to improve the microflora distribution and microenvironment in soil; and the abundant generated derivatives chelate or block the direct damage of heavy metals to the tobacco to some extent, and have the function of restoring the polluted soil. The soil conditioner contains bowlder which contains abundant microelements beneficial to the human body, and the microelements are absorbed by the crops and converted through the food chain so as to be beneficial to the human body; and meanwhile, the adsorption component can effectively adsorb and solidify toxic heavy metal elements in soil, reduce the heavy metal elements absorbed by the crops, and enhance the crop yield.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a composite microbial agent fertilizer. Background technique [0002] The existing biological fertilizers in my country are all based on organic matter, and then mixed with bacterial agents and inorganic fertilizers. The application of biological fertilizers in agriculture has been gradually recognized by people. In order to broadly improve the status quo of this traditional bio-fertilizer, researchers are committed to developing new bio-fertilizer products that can not only provide crop nutrition, but also improve soil; Eliminates pollutants in the soil and at the same time rehabilitates the soil. [0003] With the widespread application of biological fertilizers, there are no production licenses in the production of biological fertilizers in a few places, the production process is backward, and the production of unidentified strains is used for production, the content of effective bacteria is ...

AI Technical Summary

Problems solved by technology

[0003] With the widespread application of biological fertilizers, there are no production licenses in the production of biological fertilizers in a few places, the production process is backward, and the production of unidentified strains is used for production, the content of effective bacteria is low, and the miscellaneous bacteria exceed the standard; some manufacturers Inappropriate amount of chemical fertilizers or other additives are also added to biological fertilizers, so that the nitrogen, phosphorus, and potassium content of chemical fertilizers in fertilizers are too high, leading to the death of effective bacteria, thus losing the efficacy of biological fertilizers, causing plant diseases and insect pests, etc., resulting in crop yields decline
