尿素与氯化锭都是氮肥,混合施用的目的,在于充分发挥氮肥的增产效益。尿素含氮46％,是氮肥中含氮量最高的一种,它肥效高,肥效长,施用方便,深受广大农民的欢迎,但是成本高,肥料成分高,施用不当不但损失浪费,还有害作物。氯化铵含氮25％,试验表明该肥料与等量尿素肥效无显著性差异,只因肥料中氯元素(对忌氯作物有害,使低洼盐碱地碱害加重,加速排水不良地盐碱化)限制了施用范围及施肥量。该肥料成本低,肥源充足。实践证明,尿素与氯化铵混合施用,不仅有助于氮素养分有效供应,提高产量,而且还可调节肥源,降低使用成本。
Both urea and chloride ingot are nitrogenous fertilizers. The purpose of mixed application is to give full play to the yield-increasing benefits of nitrogenous fertilizers. Nitrogen nitrogen 46%, is the highest nitrogen content of a nitrogen fertilizer, its high efficiency, long fertilizer, easy to use, welcomed by the majority of farmers, but the high cost, high fertilizer composition, improper application of not only the loss of waste, but also harmful crop. Ammonium chloride 25% nitrogen, the test showed no significant difference between the fertilizer and the same amount of urea fertilizer, only because of chlorine in fertilizers (harmful to avoid chlorine crops, so that low-lying saline-alkali damage, accelerating poor drainage salinization) Limits the scope of application and amount of fertilizer. The fertilizer costs low, adequate fertilizer. Practice has proved that urea and ammonium chloride mixed application, not only contribute to the effective supply of nitrogen nutrients to improve production, but also adjust the fertilizer source, reduce the cost of use.
