Problems solved by technology

In order to obtain a stable water-soluble fertilizer, 2-chloro-6-trichloromethylpyridine can be added during the dissolution of solid water-soluble fertilizer or during the processing or dissolution of liquid water-soluble fertilizer, but due to the The solubility of pyridine in water is limited, so that its use in water-soluble fertilizers is limited, and the effect is not ideal

Abstract

The invention discloses emulsion in water for enhancing efficacy of nitrogen fertilizer. The emulsion in water is prepared from 2-chloro-6-(trichloromethyl)pyridine, an emulsifying agent, N,N-dimethylformamide and water in a certain proportion. The emulsion in water is sprayed onto the nitrogen fertilizer after the nitrogen fertilizer is screened and before the screened nitrogen fertilizer is packaged, a good adhesion effect is achieved, the condition that the emulsion in water is added before pelletizing is avoided, waste is reduced, operation environment is protected, and the problem that 2-chloro-6-(trichloromethyl)pyridine is sparingly soluble is solved, so that the emulsion in water can be applied to nitrogenous water-soluble fertilizer.

Description

technical field [0001] The invention relates to a composition, in particular to a water emulsion for nitrogen fertilizer synergism and its application in manufacturing stable fertilizers. Background technique [0002] In 2010, my country's chemical fertilizer consumption was more than 100 million tons, ranking first in the world, but the utilization rate of chemical fertilizers in that year was only 30%-35%, of which nitrogen fertilizer utilization rate was 30%-35%, phosphorus fertilizer was 10%-20%, potash fertilizer 40%-50%, far below the level of developed countries (50% 60%). In 2011, the economic value of nitrogen fertilizer loss in my country was 60 billion to 80 billion. The negative effects of lost nitrogen fertilizer on groundwater, surface water and atmospheric environment are becoming more and more serious. Due to the rapid transformation of nitrogen in the soil, phosphorus and potassium are quickly fixed by the soil, and the crops cannot absorb it for a long tim...
