Abstract

The invention discloses a high-nutrient microbial bacterium composite fertilizer and a production method thereof. The high-nutrient microbial bacterium composite fertilizer comprises the following components in parts by weight: 16-190 parts of double-wall layer composite microbial bacterium microcapsules (containing 3-5 parts of composite microbial bacteria), 150-450 parts of monoammonium phosphate, 0-400 parts of urea powder, 100-200 parts of potassium chloride, 200-350 parts of ammonium chloride, 20-100 parts of ammonium bicarbonate, 0-150 parts of ammonium sulfate and 0-50 parts of attapulgite. The production method comprises the following steps: adsorbing the microbial bacteria by adopting germ powder thereof, performing first wall layer embedding by adopting a chemical cross-linking method, performing second wall layer embedding by adopting a spray drying process, and finally coating on the surface of chemical fertilizer granules, and split charging. The composite fertilizer is sufficient in nutrient and high in viable count, so that the microbial bacteria can be slowly released, yield increase of crops is guaranteed, the incidence rate of insect pests is reduced, and soil hardening caused by application of chemical fertilizers is improved.

Description

technical field

[0001] The invention belongs to the field of fertilizers, and in particular relates to a high-nutrient microbial bacteria compound fertilizer, and also relates to a production method of the fertilizer. Background technique

[0002] Chemical fertilizers are the mainstream fertilizers in agricultural production at present. When they are added in large quantities to the soil, the effective utilization rate of various nutrients is not high, only reaching 70%. The excess nutrients not only cannot be absorbed by crops, but also cause soil fertility and moisture content to decrease. , soil compaction. Microbial fertilizers can improve the soil, improve soil fertility, increase the absorption and utilization of plant mineral elements, enhance crop resistance, drought resistance, increase yield, and improve quality. played an irreplaceable role. Therefore, adding microbial agents to chemical fertilizers can not only provide sufficient nutrition for the growth of cro...
