Abstract

The invention relates to a humic acid synergistic high-tower compound fertilizer and a production method thereof. The method includes steps as follows: preparation of a humic acid synergistic liquid, preparation of a humic acid-urea melting liquid, pretreatment of other fertilizers, graduation and the like. According to the humic acid synergistic high-tower compound fertilizer, active ingredients in a humic acid synergist have effects on promoting the growth of crops, inhibiting urease in the soil, influencing characteristics of chemical valence bonds of urea and preventing fixing of phosphorus and potassium, so that the yield of the crops and the utilization rate of the fertilizer are increased, the nutrient loss is reduced, and secondary pollution is avoided. According to the fertilizer, secondary processing doesn't exist, and the fertilizer has the characteristics of wide sources of raw materials, low possibility of deliquescence, convenience in transportation and application, simple production process, low cost, benefit to industrial popularization, and the like, thereby having a wide application prospect in production.

Description

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