窑灰钾颗粒剂在水稻上的应用效果初探

Preliminary studies on application efficiency of potash granules from cement kiln ash to rice

窑灰钾颗粒剂在水稻上进行应用试验,结果表明:窑灰钾颗粒剂对水稻增产效果与氯化钾肥相当,较硫酸钾肥增产达显著水平,且窑灰钾颗粒剂生产成本较低,经济效益高,产投比高。

An application efficiency of potash granules from cement kiln ash to rice was carried out. The results showed that the rice yield-increasing effects of potash granules from cement kiln ash were equivalent to that of potassium chloride, and much higher than potassium sulfate. Furthermore, it possesses merits of lower manufacturing costs, higher economic benefit and higher ratio of output to input.
