化学及生物活化钾长石的释钾效果比较

摘要

The comparison on chemical, biological activation and combination of chemical-biological activation on potassium release from K-feldspar were performed by shake flask culture and pot experiment. The results showed that the effects of chemical and biological activation on potassium released from K-feldspar were obvious and the amount of released potassium increased. The activated potassium released from K-feldspar with chemical, biological activation could promote the growth of maize. Between the two treatments, chemical activation was better. The effects of combination of chemical and biological activation were better than that of the single activation, which showed that the synergistic effect on combination of chemical and biological activation.%通过摇瓶培养和盆栽试验,对化学、生物及化学-生物联合作用的活化钾长石的释钾效果进行比较.结果表明,化学、生物处理对钾长石均有活化效果,可增加钾释放量；化学、生物活化钾长石对玉米生长有促进作用,而且化学活化效果更优；化学-生物联合活化具有协同作用,活化效果更显著.
