当前,复合肥料深受广大农民欢迎,现将一种既简单,又方便的自制复合肥料的方法介绍如下。(一)配方计算法。水稻配制的比例为氮:磷:钾=1∶0.4∶0.8,那么,要配制复合肥100公斤需碳酸氢铵(含氮16%)过磷酸钙(含磷20%)和氯化钾(含钾60%)各多少公斤?每百公斤混合肥料中应含有的氮磷钾的致量和相当于碳酸氢 At present, the compound fertilizer is welcomed by the majority of farmers, now a simple and convenient method of self-made compound fertilizer is as follows. (A) formula calculation method. The proportion of rice preparation is nitrogen: phosphorus: potassium = 1: 0.4: 0.8, then, to formulate 100 kilograms of ammonium bicarbonate (16% nitrogen) of superphosphate (20% phosphorus) and potassium chloride Potassium 60%) how many kilograms? The yield of NPK that should be contained in every 100 kilograms of compost and the equivalent of bicarbonate
