Development of monoammonium phosphate containing potassium fulvate and its fertilizer efficiency
Adding synergists to improve the effectiveness of phosphate fertilizers is an effective means to achieve the goal of reducing application and increasing efficiency.As a biostimulant,fulvic acid added to phosphate fertilizers has the effect of improving phosphate fertilizer utilization rate,enhancing crop stress resistance,and improving crop quality.In the production process of monoammonium phosphate,mineral source potassium fulvate is added to produce monoammonium phosphate containing a certain amount of potassium fulvate.The determination method of fulvic acid is improved,and its application effect is studied.The technical indicators of the obtained fertilizer product meet the national standard requirements for monoammonium phosphate.Compared with ordinary monoammonium phosphate treatment,the treatment with monoammonium phosphate containing mineral potassium fulvate has a certain yield increasing effect on Chinese cabbage,which is increased by 14％in average,and improves fertilizer utilization efficiency.
