Abstract

The invention discloses an organic microbial fertilizer harmless to the environment. The organic microbial fertilizer is prepared from the following components: a compound microbial agent, straw, sludge, human and animal excreta, calcium oxide, ammonium polyphosphate, urea, calcium superphosphate and water. In order to reduce the content of heavy metals in the fertilizer, the thiobacillus ferrooxidans is used for domesticating the sludge, and bioleaching is combined, so that the obtained sludge is precipitated, and the content of the heavy metals is very low; the added calcium oxide can effectively kill harmful viruses in the fertilizer; organic matters in the fertilizer are converted through an aerobic denitrifying bacteria inoculant, so that organic pollutants in the fertilizer are reduced, and the nitrogen fertilizer content of the fertilizer is increased. The organic microbial fertilizer is harmless to the environment, effectively treats sludge, straws and other organic wastes harmful to the environment, and is environment-friendly and safe.

Description

Technical field [0001] The invention relates to the technical field of microbial fertilizers, in particular to an organic microbial fertilizer that is harmless to the environment. Background technique [0002] There are many types of microbial fertilizers. Generally, microbial fertilizer products are divided into two categories: one is the narrowly defined microbial fertilizer, which refers to the increase in the supply of plant nutrients through the life activities of microorganisms, including the improvement of plant nutrition in the soil and production environment The total supply of the elements leads to the improvement of plant nutritional status and thus the increase in yield. The representative species of this type of microbial fertilizer is rhizobia fertilizer; the other is the generalized microbial fertilizer, which refers to the life activities of microorganisms in it, not only can Increasing the supply of plant nutrient elements can also produce plant growth hormones, ...
