Problems solved by technology

[0002] my country's agriculture is currently facing serious problems in the following aspects: (1) In agricultural production, excessive use of inorganic fertilizers and insufficient use of organic fertilizers have resulted in a serious shortage of organic matter content in cultivated land, and a serious decline in air permeability and water storage, resulting in The destruction of the soil ecological environment has resulted in a decrease in the number of soil microbial flora, poor growth of plant roots, and a reduction in the quality of agricultural products. At the same time, it has caused a series of environmental pollution problems such as eutrophication of lake water and excessive nitrate in drinking water; (2) a large number of Agricultural waste such as crop stalks and livestock and poultry manure cannot be used as resources. The incineration of straw and the disposal of livestock and poultry manure not only seriously pollute the ecological environment, but also a huge waste of resources; (3) my country's current chemical fertilizers are more than Quick-acting fertilizers are mainly used. Due to leaching and volatilization in the soil, serious loss of fertilizer nutrients is caused, and the utilization rate of fertilizers is low. The utilization rate of nitrogen fertilizer is only 30-40%, phosphorus fertilizer is about 10-25%, and potassium fertilizer is 35-50%. %
However, the above-mentioned patents all granulate organic fertilizers, inorganic fertilizers, biological beneficial bacteria, and trace elements together. During the granulation process, it is easy to cause the death of biological beneficial bacteria. In addition, the granulation of trace elements and phosphate fertilizers is easy to be fixed by phosphate fertilizers, resulting in Waste of phosphorus and trace elements

Abstract

The invention discloses a biological organic-inorganic loss-controlled fertilizer with a core-shell structure. The biological organic-inorganic loss-controlled fertilizer comprises a core layer and a shell layer. The core layer is made of inorganic fertilizer granules; the shell layer material is formed in the way that feces of livestock and poultry and straw meal are fermented, and then the fermented feces of livestock and poultry, the fermented straw meal, bentonite, microelement fertilizer, polyaspartic acid and ammonium humate are mixed evenly and then ground; the core layer and the shell layer materials are mixed evenly, then granulated, sprayed with biological probiotics, dried at a low temperature and then screened, and the finished product is obtained. By means of the design of the core-shell structure, on one hand, the biological probiotics can be prevented from making direct contact with the inorganic fertilizer, and caking of the fertilizer can be avoided; on the other hand, the effect of reducing the dissolution rate of nutrients in the core layer can be achieved. By means of humate, polyaspartic acid, bentonite and other ingredients contained in the shell layer and active matter generated by activity of the probiotics in soil, inorganic nutrients of the core layer can be adsorbed, fixed nutrients in the soil can be activated, and thus the utilization rate of the fertilizer can be greatly increased. The loss-controlled fertilizer is low in cost and can be widely used for planting field crops such as corn and wheat.
