Problems solved by technology

[0004] However, during the fertilization process of organic fertilizer, it is easy to infiltrate with water in the soil, causing some nutrients to migrate to the depth of the soil synchronously, while the absorption capacity and range of crop roots are limited, which causes a part of the nutrients to be absorbed when the organic fertilizer is applied. There is waste, and it is difficult to be directly absorbed by the roots of the crops, resulting in a significant increase in the actual amount of organic fertilizers compared to the demand of the crops

Abstract

The invention discloses a fixed-point application method of low-diffusion rate organic fertilizer, which belongs to the technical field of organic fertilizer. The invention can send the organic fertilizer to the root of the crop in the soil at a fixed point by loading the carrier ball with the organic fertilizer, and then water the organic fertilizer. When the carrier ball absorbs water, it will trigger the release of organic fertilizer, and at the same time, the carrier ball will change from a closed state to a connected state with the outside world. After the air in the soil enters, it will trigger a chemical reaction to generate a certain amount of heat, thus forcing the carrier ball to carry out The expansion blocks the penetration path of water, and at the same time accelerates the splitting and disintegration of the surface organic fertilizer to facilitate rapid dissolution. In addition, the carrier ball will release oil substances, which penetrate at the bottom of the carrier ball before water, and then at high temperature The increased viscosity under the action can form an oil film, which can significantly improve the penetration barrier effect on water, and ensure that the crop roots can fully absorb the dissolved organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a fixed-point application method of low diffusivity organic fertilizers. Background technique [0002] Fertilization can not only improve soil fertility, but also an important measure to increase the yield per unit area of ​​crops. At present, chemical fertilizers are used more. my country is both a big producer and a big user of chemical fertilizers. For many years, the increase in agricultural production and harvest is inseparable from chemical fertilizers. However, chemical fertilizers also bring problems that cannot be ignored. After years of research, agricultural experts have found that the hidden losses of chemical fertilizers are very serious. In the soil with excessive application of chemical fertilizers, the content of inorganic matter soars, organic matter weakens, trace elements are unbalanced, and crop diseases and insect pests become more and more serious....
