Abstract

The invention provides a diammonium phosphate synergistic fertilizer and a preparation method thereof. The synergistic fertilizer consists of 98-99 percent of diammonium phosphate and 1-2 percent of diammonium phosphate synergist, wherein the diammonium phosphate synergist comprises 14-16 percent of humic acid, 0.01-0.02 percent of zinc and 0.02-0.03 percent of boron, the pH value is 9-11 and the phosphorous fixed rate is reduced by at least 20 percent. The diammonium phosphate synergistic fertilizer formed after diammonium phosphate and synergist are combined has remarkable characteristics of reducing phosphorus fixation, greatly improving phosphorus activity, promoting crop root growth, improving root activity, remarkably increasing crop yield, improving fertilizer utilization rate, supplying trace elements to soil and the like, and is environmentally friendly. Furthermore, the preparation method has the advantages of simple preparation process, wide raw material source, easiness in operation, low cost and the like.

Description

technical field [0001] The invention relates to a diammonium phosphate synergistic fertilizer and a preparation method thereof, belonging to the technical field of chemical fertilizers. Background technique [0002] The application of chemical fertilizers is an important measure to ensure high and stable grain production. In this century, 1 / 2 of the world's grain production per unit area and 1 / 3 of the total output come from the contribution of chemical fertilizers. If chemical fertilizers were stopped, global crop yields would drop by 50%. The contribution rate of chemical fertilizers to my country's grain production is as high as 40% to 60%. It is self-evident that chemical fertilizers play an important role in food security. At the same time, there have been problems such as irrational use of chemical fertilizers and unbalanced nutrients in my country for many years, which not only caused low nutrient utilization, waste of resources, increased agricultural input costs, ...
