High-efficient controlled release compound fertilizer and preparation method thereof

Abstract

The invention provides a high-efficient controlled release compound fertilizer and a preparation method thereof. The fertilizer belongs to a mixed fertilizer which can control the release speed of nutrition constituent. The fertilizer contains 20 to 50 parts by weight of enveloped release controlling compound fertilizer and 80 to 50 parts by weight of release nitrogen fertilizer containing enzymeinhibitor and nitrifying bacteria inhibitor. The fertilizer and the preparation method provided by the invention have reasonable and scientific prescription of nutrition constituent, are matched withthe growing requirement of plants, are easy to control the degradation rate of fertilizer and release rate of nutrition constituent, are adapted to the nutrition constituent adsorbing rate of plant, increase the quantity and quality of agricultural products, promotes the use ratio of fertilizer, decrease fertilizing amount, lower the manufacturing cost of agricultural products, are beneficial to protecting soil and natural environment, and are widely applied to fertilizing soil for grain, fruit trees, vegetables, economic crops, and the like.

Description

technical field [0001] The invention relates to a high-efficiency controlled-release compound fertilizer and a preparation method thereof. It is a compound fertilizer that can control the release rate of nutrients. 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 large share in the investment in the agricultural industry, and tend to have adverse effects on the soil environment and the natural environment. Therefore, the combination of nutrients is scientific and reasonable to match the needs of plant growth; the degradation rate of fertilizers and the release rate of nutrients are easy to control and adapt to the rate of absorption of nutrients by plants; the rate of fertilizer degradation and nitrification is slowed down to reduce fertilizer consumption. leaching and NO, NO 2 , NH 3 The gas form enters the atmosphere, thereby improving...

Problems solved by technology

However, the controlled-release fertilizers in the prior art rely on single-layer or multi-layer coatings and the addition of inhibitors to control the release rate of chemical fertilizer nutrients, and the effect is not ideal; the adjustment of fertilizer components is not flexible enough, and the manufacturing process is complicated and the cost is high; Pollution to soil and natural environment
