Abstract

The invention provides a preparation method of a leguminous forage grass fertilizer in a rain-abundance period. The leguminous forage grass fertilizer is prepared from the preparation raw materials: 12 parts of urea (containing 46% of N), 8 parts of pig farm fermented biogas slurry, 14-16 parts of a phosphate fertilizer (based on P2O5), 7-10 parts of a potash fertilizer (based on K2O), 8 parts ofmicrobial inoculants and 20 parts of distilled water. In a step A, the pre-fermentation work comprises a user places 12 parts of urea, 8 parts of pig farm fermentation biogas slurry, 14-16 parts of the phosphate fertilizer (based on P2O5), 7-10 parts of the potash fertilizer (based on K2O) and 20 parts of distilled water into a stirrer in advance to be mixed and stirred in a sealed mode, the mixture is mixed and stirred to be uniform, early ammoniation treatment is conducted, and a fermentation raw material is obtained; according to the invention, the flow processes of the step A, the step B,the step C and the step D are matched; the microbial fertilizer with high content of nitrogen, phosphorus, potassium and other elements can be prepared, then microbial inoculation fertilization can beperformed on grass roots of forage grass, the utilization rate of nitrogen, phosphorus, potassium and other elements is increased, the fertility of the microbial fertilizer is further enhanced, and then soil with abundant fertility provides a growth environment with high nutrition for the pasture.

Description

technical field [0001] The invention relates to the field of forage fertilizers, in particular to a preparation method of leguminous forage fertilizers in the rainy season. Background technique [0002] Grass, generally refers to grass or other herbaceous plants used by livestock. Forage grass has strong regeneration ability, can be harvested many times a year, and is rich in various trace elements and vitamins. Therefore, it has become the first choice for raising livestock. It affects the level of economic benefits of animal husbandry and needs to be paid attention to. [0003] Pasture is the most affordable feed for livestock breeding. When planting pasture, farmers need to spread fertilizer. However, the existing method for preparing pasture fertilizer is relatively low in fertility, and it is impossible to inoculate and fertilize the grass roots of pasture. At the same time, Some forage fertilizers contain less than 35% nitrogen, phosphorus and potassium, which cannot ...
