Controlled-release efficacy-improved biological fertilizer and preparation method thereof

Abstract

The invention discloses a controlled-released efficacy-improved biological fertilizer and a preparation method thereof. The fertilizer comprises a nitrogen phosphorus and potassium compound fertilizer, microelements and a compound additive; the compound additive comprises a nitrification inhibitor, a urease inhibitor, phosphate solubilizing bacteria and humid soil. According to the fertilizer disclosed by the invention, the problem that an existing controlled-release fertilizer is high in cost in film coating, wrapping, encapsulation, coating and the like is solved; the occurrence of diseases and insect pests can be reduced; the content of moisture in soil is adjusted and kept; the air ventilation of soil is improved; the fertilizer efficacy is kept; the growth of plants is promoted; microbes capable of promoting the growth of plants are increased. The fertilizer is a complex containing multiple nutrients rather than a chemical fertilizer single in nutrient component, is also rich in amino acids, humic acids, calcium, sulfur, zinc, iron, boron and other more than twenty quality-elements essential for plants in addition to nitrogen, phosphorous, potassium and other plenty of nutrition elements and plays roles in adjusting oil and balancing nutrition.

Description

technical field [0001] The present invention relates to the field of fertilizers. More specifically, it relates to a slow-release synergistic biological fertilizer and a preparation method thereof. Background technique [0002] Crops 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 the necessary nu...

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 slow-release synergistic fertilizer that saves costs, has a simple preparation method, and is economical and environmentally friendly.
