Abstract

The invention relates to a polyamino acid fertilizer auxiliary and a preparation method for the same. The method comprises the three steps of preparation of a mixed catalyst, preparation of mixed amino acid salt and preparation of the polyamino acid fertilizer auxiliary. The invention also relates to the use of the polyamino acid fertilizer auxiliary for the production of urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfide, a compound fertilizer or a medium trace element fertilizer or for fertilizer drip-irrigation, spray irrigation and microspray irrigation systems, wherein the weight ratio of the fertilizer auxiliary to the fertilizer is (5-100):1000. According to the polyamino acid fertilizer auxiliary, the preparation method and the use, the activity of root systems of crops can be improved, the yield of the crops can be remarkably increased, the apparent utilization ratio of a nitrogenous fertilizer can be increased, and the volatilization loss of ammonium is reduced; the product has the characteristics of environment friendliness, supplementation of the trace elements to soil and the like.

Description

【Technical field】 [0001] The invention belongs to the technical field of chemical fertilizer efficiency enhancement. More specifically, the present invention relates to a polymeric amino acid fertilizer additive, and also relates to a preparation method of the fertilizer additive. 【Background technique】 [0002] The utilization rate of chemical fertilizers in my country is generally low. The average utilization rate of nitrogen fertilizer is about 30%, the seasonal utilization rate of phosphorus fertilizer is about 25%, and the utilization rate of potassium fertilizer is about 50%. Fertilizer science and technology workers have done a lot of research on ways and methods to improve fertilizer utilization, and achieved certain results, but there are still problems such as complex fertilizer production process, high cost, inconvenient use, and difficulty in popularizing and applying fertilizers on field crops. In recent years, how to upgrade the technology of my country's fert...
