摘　　要：窑灰钾颗粒剂是一种近年来以水泥窑灰为主要原料的新型粒状钾肥。经大田试验表明:在山区冷烂田水稻栽培上施用窑灰钾颗粒剂增产效果优于氯化钾和硫酸钾;施用窑灰钾颗粒剂与氯化钾处理差异不显著,氯化钾与硫酸钾处理差异不显著;施用窑灰钾颗粒剂与硫酸钾处理之间差异达显著水平;与不施钾肥对照区相比,3种钾肥增产效果均达极显著水平。使用窑灰钾颗粒剂具有生产成本较低,产投比大的特点。Granules of the cement kiln ash potash is a kind of cement kiln ash as the main raw materials in recent years a new type of granular fertilizer. By the field experiment showed that in the mountains cold bad field applying potassium kiln dust granules on rice cultivation production effect is better than that of potassium chloride and potassium sulfate; Application of kiln ash between potassium granules and potassium chloride, potassium sulfate and potassium chloride and no significant difference between treatment; Applying potassium kiln dust granules and significant differences between potassium sulfate treatment; Compared with the control area without potash, three kinds of potash production have reached extremely significant level. Using potassium kiln dust granules production cost is low.
