Problems solved by technology

In my country, due to the long-term use of chemical fertilizers, the shortage of organic fertilizers and the imbalance of various nutrient ratios, the ecological environment of farmland, soil physical and chemical properties and soil microbial flora have been damaged to varying degrees, which has affected the safety of agricultural products to a certain extent.
At present, there are two problems in the application of chemical fertilizers in our country: one is the large amount of chemical fertilizers used and the utilization rate is low; the other is that the unreasonable application of chemical fertilizers causes environmental pollution and reduces the quality of agricultural products.

Abstract

The invention discloses compound microbial film-coated slow-release fertilizer, which is prepared from the following raw materials in parts by weight: 100-120 parts of fertilizer core, 2-3 parts of film-coated layer and 4-7 parts of composite microbial layer. The invention also discloses a preparation method of the compound microbial film-coated slow-release fertilizer. The compound microbial film-coated slow-release fertilizer has the advantages of being balanced in nutrition, long in effective living bacterium survival time, high in fertilizer utilization rate and stable in product quality,and having excellent performance of improving the soil micro-ecological environment, and can reach the requirements of reducing fertilizer and increasing effect as well as being green and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a composite microorganism-coated long-acting fertilizer and a preparation method thereof. Background technique [0002] As we all know, chemical fertilizers are the "grain" of food. In my country, due to the long-term use of chemical fertilizers for many years, the shortage of organic fertilizers and the imbalance of various nutrients have caused the ecological environment of farmland, soil physical and chemical properties and soil microbial flora to be damaged to varying degrees, which has affected the safety of agricultural products to a certain extent. . At present, there are two problems in the application of chemical fertilizers in my country: one is the large amount of chemical fertilizers used and the utilization rate is low; the other is that the unreasonable application of chemical fertilizers causes environmental pollution and reduces the quality of agr...
