Abstract

The invention relates to a glutamic acid synergistic high-tower compound fertilizer and a production method thereof. The method comprises the steps of glutamic acid synergist preparation, glutamic acid-urea melt liquid preparation, preprocessing of other fertilizers, pelleting and the like. The glutamic acid synergistic high-tower compound fertilizer can promote the increase of crop roots and improve the root activity, and can not only improve the utilization rate of a nitrogen fertilizer, but also can improve the utilization rates of a phosphate fertilizer and a potash fertilizer. In cultivation, the agricultural operation can be simplified; in benefit, the nutrient utilization rate can be improved by 5-10%; the compound fertilizer can improve the capacity of crops for absorbing nutrients through functions of promoting the growth of crop roots and enhancing the root activity; and nutrient loss can be reduced, secondary pollution is avoided, and the agricultural production cost is reduced. In production of compound fertilizers, the glutamic acid synergist is simple in additive process and low in cost; and in production of synergistic compound fertilizers and industrial application, the glutamic acid synergist has a wide application prospect.

Description

【Technical Field】 [0001] The invention belongs to the technical field of agricultural chemicals. More specifically, the present invention relates to a glutamic acid synergistic high-tower compound fertilizer, and also relates to a production method of the glutamic acid synergistic high-tower compound fertilizer. 【Background technique】 [0002] At present, the fertilizer compounding rate in my country is about 32%, and the physical output is about 55 million tons. A large number of studies have shown that the nutrient utilization rate of existing compound fertilizers is low. For example, the current season utilization rate of nitrogen is about 30%, the utilization rate of phosphorus is about 25%, and the utilization rate of potassium is about 45%. Therefore, how to improve fertilizer nutrient utilization has always been a focus of attention and research. High-tower compound fertilizer is a unique fertilizer variety in my country. It has many advantages such as high productivity,...
