Stable composite (mixed) fertilizer additive

Abstract

The invention discloses a stable composite (mixed) fertilizer additive. The weight ratio of components of the additive is as follows: phenyl phosphorodiamidate: 2-chlorine-6-(trichloromethyl)pyridine: paraffin: ammonium citrate: zeolite powder = 2: 0.5-3: 2-5: 0.5-1: 4-8. The additive can adjust the effect period of a stable composite (mixed) fertilizer, obviously improves the utilization rate of nitrogen, phosphorous and potassium, and satisfies fertilizer demands of a plurality of crops.

Description

technical field [0001] The invention relates to an additive, in particular to a stable compound (mixed) fertilizer additive. 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 2010, 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 time, and it is necessary to topdress the crops many times in the ...

However, the inhibitors currently used in foreign countries are all single inhibitors, which can only control part of the process of converting amide nitrogen into nitrate nitrogen, and have not reached the ideal state.
