Abstract

The invention discloses a composite microbial fertilizer synergist and a preparation method thereof. The composite microbial fertilizer synergist is a solid granule composed of an inner core and a shell; the inner core is prepared from a composite microbial preparation, a seaweed extract and a first adhesive, and composite microorganisms are adsorbed on the surface and inside of particles of the seaweed extract; and the shell comprises a compound amino acid preparation, modified sepiolite fabric, a pore-foaming agent, a disintegrating agent and a second adhesive. The modified sepiolite fabric is prepared by the following steps: acidizing sepiolite fabric to prepare slurry, adding a silane coupling agent, and drying. The composite microbial fertilizer synergist is prepared into an inner-outer double-layer structure, a special mode that the outer layer contains composite amino acid and the inner layer contains composite microorganisms is adopted, and after common fertilizer is combined for use, the soil fertility can be remarkably improved, the beneficial microbial environment in soil can be improved, and crop growth can be promoted.

Description

technical field [0001] The invention belongs to the field of fertilizer synergists, in particular to a compound microbial bacteria fertilizer synergist and a preparation method thereof. Background technique [0002] Fertilizer synergists refer to a class of active substances for the purpose of increasing nutrient availability, usually in combination with conventional fertilizers. By playing a series of special functions such as nitrogen fixation and activation of phosphorus and potassium elements that are difficult to use in the soil, it can improve the nutrient distribution and soil fertility in the soil, promote the absorption of nutrients in the soil by plants, and regulate certain physiological functions of plants. There are many types of fertilizer synergists, which can be divided into nitrification inhibitors, urease inhibitors, nutrient activators, water retention agents, etc. in terms of function. Applying appropriate fertilizer synergists can effectively improve th...
