Particle microorganism fertilizer and manufacturing method thereof

Abstract

The invention discloses particle microorganism fertilizer. The particle microorganism fertilizer is characterized by comprising, by weight, 50-65 parts of crop husks, 20-35 parts of inorganic fertilizer, 5-10 parts of microorganism bacterium agent, 6 parts of attapulgite powder and 5-10 parts of chitosan. The manufacturing method of the particle microorganism fertilizer includes the steps of intermediate fertilizer preparation, particle fertilizer preparation and particle microorganism fertilizer preparation. According to the step of intermediate fertilizer preparation, the crop husks are crushed to pass through a sieve of 100 meshes, and then the inorganic fertilizer and the attapulgite powder are added to be stirred, so that intermediate fertilizer is obtained. According to the step of particle fertilizer preparation, the obtained intermediate fertilizer is conventionally extruded, pelleted, dried till the moisture content is 5%-8%, and cooled to be at the temperature of 30-35 DEG C, and accordingly particle fertilizer can be obtained. The particle microorganism fertilizer has the advantages that soil crust can be avoided, meanwhile, the two actual needs of being high in fertilizer efficiency volatilization and long in action time are considered, effective microbial communities of soil can be effectively promoted to grow, the utilization efficiency of the fertilizer is improved, crop growth is promoted, treatment is easy, and cost is low.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a granular microbial fertilizer and a preparation method thereof. Background technique [0002] In the modern agricultural production system, since the cultivated soil can provide limited mineral nutrients for crops to absorb during the crop growing season, it is one of the fundamental measures to ensure crop yields to provide appropriate amount of mineral nutrients for crops through fertilization. According to statistics, Tens of millions of tons of fertilizers are applied to farmland in the world every year, while my country currently uses more than 50 million tons of chemical fertilizers every year, which is the country with the largest amount of chemical fertilizers in the world. [0003] In the process of applying chemical fertilizers, due to the phenomenon of unreasonable fertilization all the time, serious waste of chemical fertilizers and periodic crop fert...

Problems solved by technology

Therefore, the processing process of most compound fertilizers is complicated, and the physiological activity is low, and the nutrient utilization rate is not high. After being applied to the soil, it cannot quickly improve the soil ecological environment, promote the growth of beneficial bacteria, and the absorption and utilization rate of crop fertilizers is not high, so it cannot be effective. Improving soil carbon pools, less effective in repairing and improving soil structure
