Environment-friendly nitrogen phosphorus and potassium compound fertilizer

Abstract

The invention relates to an environment-friendly nitrogen phosphorus and potassium compound fertilizer which is shaped as a capsule, wherein the capsule comprises a capsule core and a coating, the capsule core comprises the following components of ground phosphate rock, ground magnesite, potassium chloride, ground potassium feldspar, borax, ammonium dihydrogen phosphate and urea. The environment-friendly nitrogen phosphorus and potassium compound fertilizer is complete in effective components, is slowly-released, effectively prevents from coagulating, and is high in utilization rate. In addition, the environment-friendly nitrogen phosphorus and potassium compound fertilizer can also be suitable for soil with different geological conditions, such as drought or moisture and growth of different crops; meanwhile, the labor cost can be saved, and the mechanized planting and fertilizing are facilitated.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers. More specifically, the invention relates to an environmentally friendly slow-release and anti-caking multi-component compound fertilizer for kitchen knives. Background technique [0002] Chemical fertilizers provide the necessary nutrients for the growth of crops, play a vital role in the yield and quality of agricultural products, occupy a relatively large share in agricultural industry investment, and tend to have adverse effects on the soil and the natural environment. In recent years, the disadvantages caused by the large-scale and disorderly use of chemical fertilizers have gradually emerged: for example: the low utilization rate of fertilizers caused by fast decomposition; the pollution of air and water caused by gases and liquids produced by decomposition; The soil ecological environment has been destroyed and so on.

Problems solved by technology

In recent years, the disadvantages caused by the large-scale and disorderly use of chemical fertilizers have gradually emerged: for example: the low utilization rate of fertilizers caused by fast decomposition; the pollution of air and water caused by gases and liquids produced by decomposition; resulting in soil compaction, The soil ecological environment has been destroyed, etc.

[0003] In the prior art, people use technologies such as adding nitrogen fertilizer slow-release agents to slow down the release of nitrogen fertilizers and improve the utilization rate of nitrogen fertilizers, and most of the slow-release fertilizers rely on single-layer or multi-layer coatings, or only rely on simple Adding inhibitors to control the release rate of fertilizer nutrients, the slow-release effect is not ideal; there are incomplete nutrients, unreasonable adjustment of fertilizer components, and the manufacturing process is complicated and costly; therefore, the combination of nutrients is scientific and reasonable. The growth needs are matched; the nutrients are released slowly to match the plant's absorption rate of nutrients; the fertilizer degradation and nitrification rate is slowed down to reduce fertilizer leaching and improve fertilizer utilization; it is beneficial to the protection of soil resources and the natural environment.
