Special slow-release synergistic fertilizer for potatoes and preparation method thereof

Abstract

The invention discloses a special slow-release synergistic fertilizer for potatoes and a preparation method thereof. The fertilizer comprises nitrogen phosphorus potassium compound fertilizer, trace elements and compounding additives, wherein the compounding additives comprise a nitrification inhibitor, a urease inhibitor, phosphate solubilizing bacteria and humus soil. According to the fertilizer, methods with higher cost, such as a film coating method, a wrapping method and a coating layer for slow-release fertilizer are avoided, crop diseases and pests can be reduced, the content of water in the soil is regulated and retained, the permeability of the soil is improved, the fertilizer efficiency is retained, harmful gases in the soil are regulated, the plant growth is promoted, and microorganisms for promoting the growth of the plants are increased. The fertilizer is not a chemical fertilizer with single nutrients, but is a complex containing multiple nutrients; except a large amount of nutrient element such as nitrogen, phosphorus and potassium, the fertilizer also is rich in more than twenty of quality elements such as amino acid, humic acid, calcium, sulfur, zinc, iron and boron, which are necessary for crops, so that the functions of regulating the soil and balancing the nutrition are realized.

Description

technical field [0001] The present invention relates to the field of fertilizers. More specifically, it relates to a special slow-release synergistic fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potatoes need to absorb more nutrients in a growth cycle, not just nitrogen, phosphorus, and potassium provided by ordinary fertilizers. According to the short board theory of wooden barrels, if there is a lack of other nutrients, it will not be able to grow and develop normally, and the plants will be thin and small, which will seriously affect the yield. At present, due to the significant increase in production of chemical fertilizers and the large-scale use of them, the soil texture is polluted and deteriorated, and the natural ecological conditions are destroyed. In particular, the utilization rate of fertility is low, which not only wastes resources, but also pollutes the environment. [0003] Reasonable fertilization can provide nut...

AI Technical Summary

Problems solved by technology

At present, slow-release fertilizers at home and abroad are generally fertilizers that prolong the fertilizer effect by physical methods such as coating, wrapping, encapsulation, and coating, and wrapped fertilizers formed by mixing instant fertilizers with rubber emulsion and industrial and agricultural waste. These fertilizers are expensive, and do not have the characteristics of rich voids, increased ground temperature, increased soil fertility, and improved soil structure. Therefore, it is very necessary to develop a special potato fertilizer that saves costs, has a simple preparation method, and is economical and environmentally friendly.
