用总养分质量分数为47%、53%、55%、60%、73%的磷酸一铵分别与尿素、硫酸钾等配制成5种等养分含量(15-15-15)的复合肥(1#~5#),以萝卜为试验对象,通过盆栽试验,考察了5种复合肥对萝卜生长指标和品质指标的影响。结果表明:2#、3#、4#复合肥处理的萝卜生长指标优于1#、5#复合肥处理的;1#~4#复合肥处理的萝卜中维生素C和可溶性糖含量优于5#复合肥处理的。在复合肥生产中,除非受原料配比的影响,建议优选低总养分含量的磷酸一铵为原料。
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.
