Problems solved by technology

[0002] At present, my country has become a big country in the use of fertilizers. The amount of fertilizers is increasing every year, but the utilization rate of fertilizers is not high. The utilization rate of nitrogen fertilizer in our country is only about 35%, and the utilization rate of phosphorus fertilizer is even lower, only 10%-25%. Fertilizers are not used by crops and are wasted in vain. How to improve the utilization rate of fertilizers in our country has become a top priority. Many people have invented fertilizer synergists before this invention, but their inventions are relatively simple, just using urine Enzyme inhibitors or nitrification inhibitors, or phosphorus activators alone

Abstract

The invention relates to a fertilizer controlled release agent which is characterized by comprising the following components in percentage by weight: 0.2-15 percent of urease inhibitor and nitrification inhibitor, 0.1-18 percent of cytokinin, 1-25 percent of phosphorin activator and 42-98.7 percent of filler. In the process of producing compound fertilizers, the fertilizer controlled release agent is added in proportion, which can improve the utilization ratio of the fertilizers, save the fertilizers and achieve the purpose of fertilizing at a time without additional fertilizers, and on the basis of an equivalent fertilizer dose, the effect of increasing the yield by 6-18 percent can be realized.

Description

Technical field: [0001] The invention relates to the field of fertilizer additives, in particular to a novel fertilizer synergist for controlling the release of nutrients. Background technique: [0002] At present, my country has become a big country in the use of fertilizers. The amount of fertilizers is increasing every year, but the utilization rate of fertilizers is not high. The utilization rate of nitrogen fertilizer in our country is only about 35%, and the utilization rate of phosphorus fertilizer is even lower, only 10%-25%. Fertilizers are not used by crops and are wasted in vain. How to improve the utilization rate of fertilizers in our country has become a top priority. Many people have invented fertilizer synergists before this invention, but their inventions are relatively simple, just using urine Enzyme inhibitors or nitrification inhibitors, or phosphorus activators alone. The present invention not only combines inhibitors and activators but also uses cytokini...
