Problems solved by technology

[0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil The impact of environmental conditions and agricultural measures, etc., the utilization rate of chemical fertilizers is very low

Abstract

A fertilizer provided by the invention has a double-layer structure, and comprises a soil improvement formula and organic fermented materials in the outer layer and NPK nutrients in the inner layer. The fertilizer is sprayed on surfaces of crops according to conventional manners. The soil improvement formula and the organic fermented materials, which are at the surface layer, enter soil preferentially, and have multiple effects of improving soil, increasing soil organic matters, retaining water, controlling soil hardening, and the like. Medical stone smashed into particles improves soil properties, makes soil sandy and allows inner enveloped chemical mineral elements to directly act on roots, thus effectively preventing and controlling loss caused by rain washing, allowing effective components to be utilized, saving energy, and protecting the environment. A special slow-release resin enveloping agent is free of pollution, forms a loose and porous structure during a slow degradation process, and has excellent slow release effects and an effect of reserving water.

Description

technical field [0001] The invention relates to a high-efficiency root-acting fertilizer and a preparation method thereof, belonging to the technological field of high-efficiency slow-release fertilizers in fertilizers. Background technique [0002] Chemical fertilizer is the largest material input in agricultural production. According to the statistics of the Food and Agriculture Organization of the United Nations, chemical fertilizers account for 40-60% of the increase in yield. However, the production time shows that due to the nature of the fertilizer itself and the soil Due to the impact of environmental conditions and agricultural measures, the utilization rate of chemical fertilizers is very low. The waste of nutrient resources caused by the low utilization rate of fertilizer nutrients in China is astonishing. According to statistics, the annual production and application of nitrogen fertilizer in China is about 20 million tons, and the seasonal utilization rate of fe...
