| 摘 要： | 针对钾长石高温煅烧能耗高的问题,在900°C下加入复方活化剂对钾长石进行降温煅烧,并对制得的活性钾肥肥效进行玉米盆栽试验和大田试验验证。结果显示,活化钾肥产品的水溶性钾含量明显提升,较未活化前增加26倍;在钾养分减少45%的条件下,活化钾肥的肥效与氯化钾相当,其淋溶钾损失减少,作物吸钾量提高。活化钾肥是实现"减量增效"的新型肥料。

| Abstract: | In order to save energy consumption of potassium feldspar calcining,combined activator is used for calcining under 900 ℃.The effects of activated potassium fertilizer on maize are tested by pot and field experiments.The results show:water-soluble potassium of the potassium feldspar increases obviously,which is increased by 26 times compared to potassium feldspar;With reducing 45％ K,activated potassium fertilizer keeps same fertilizer effect as KCl,showing less K leaching and higher K uptake.It is a new potassium fertilizer for "Decrement and Synergism". |

| Keywords: | activated potassium fertilizer calcine combined activator fertilizer effect |
