Abstract

The invention discloses microbial slow-release compound fertilizer. The microbial slow-release compound fertilizer is prepared from the following raw materials in parts by weight: 6-15 parts of rich hull biomass charcoal, 15-26 parts of fermented organic fertilizer, 3-8 parts of potassium fulvic acid, 4-9 parts of monoammonium phosphate, 18-25 parts of urea, 6-11 parts of lignin, 9-20 parts of montmorillonite, 1-5 parts of bacterium-containing concentrated liquid, 8-12 parts of polyvinyl alcohol, 14-18 parts of corn starch, 1-3 parts of oxalic acid, and 0.2-0.5 part of silicon dioxide. The invention further provides a preparation method of the microbial slow-release compound fertilizer. According to the microbial slow-release compound fertilizer, multiple controllable release of the fertilizer efficiency can be achieved, microbial species are large in number and high in survival rate, after the microbial slow-release compound fertilizer is applied, the probiotic environment can be quickly formed in soil, the fertilizer maintenance and water retention abilities of the soil are improved, and the disease resisting ability of crops can further be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a microbial slow-release compound fertilizer and a preparation method thereof. Background technique [0002] my country is a country with a large agricultural development, and it is also the largest producer and user of chemical fertilizers in the world. The annual amount of chemical fertilizer application accounts for 35% of the world's total, but the utilization rate of chemical fertilizers is far lower than that of developed countries. Among them, the utilization rate of nitrogen fertilizer is 30% to 50%. The seasonal utilization rate of phosphate fertilizer is 8% to 20%, and the utilization rate of potassium fertilizer is about 50%. It is of great significance to improve the utilization rate of fertilizer and reduce its pollution to the environment. The development of slow and controlled release fertilizers is an important way to solve this problem. [0003] Microbial fe...
