摘  要:
在土壤速效钾 (K2 O)低于 10 0mg/kg的水稻土上施用钾肥具有显著的增产效果 ,水稻施用钾肥以基肥或早期追肥增产效果最好 ,据试验研究 ,在桂林市缺钾水稻土上最佳钾肥施用量为K2O15 2 8kg/hm2 ,最佳施钾时的水稻产量为 76 32 3kg/hm2 。

摘  要:
In paddy soil, when rapid available potassium(K 2O) is lower than 100 mg/kg, the application of potassium fertilizer will get obvious higher output of rice. The output increase effect will be the best when potassium fertilizer is applied as the basic fertilizer or top application in early period. According to the experiments and study, the best applying quantity of potassium fertilizer K 2O in paddy soil that lack of potassium in Guilin City was 152.8kg/hm 2 while the corresponding rice output was 7632.3kg/hm 2.
