Comparison of Fertilizer Efficiency of Monoammonium Phosphate with Different Total Nutrient Contents
Five compound fertilizers(1#to 5#)with equal nutrient content(15-15-15)are formulated using monoammonium phosphate with a total nutrient mass fraction of 47%,53%,55%,60%,and 73%,respectively,along with urea and potassium sulfate.Radish is used as the experimental object,and the effects of the five compound fertilizers on the growth and quality indicators of radish are investigated through a pot experiment.The results show that the growth indicators of radish treated with 2#,3#,and 4#compound fertilizers are better than those treated with 1#and 5#compound fertilizers.The content of vitamin C and soluble sugar in radish treated with compound fertilizer 1#to 4#is better than that treated with compound fertilizer 5#.In the production of compound fertilizers,unless affected by the ratio of raw materials,the low total nutrient content monoammonium phosphate as the raw material is recommended to choose.
