摘要
研究了钾素肥源在水稻和小麦上的施用效果,以及对土壤钾素水平的影响。结果表明:施用不同钾素肥源均可增加水稻和小麦产量,水稻增产是通过增加穗数和每穗实粒数来实现的,小麦增产则是通过增加穗数、每穗粒数和粒重来实现的。施用钾素肥源还可增加土壤速效钾含量,尤以施用化学钾肥效果最为明显。
The application effect of potash fertilizer on the rice and wheat and it＇s influencing to the potash level in the soil were tested. The results showed that the yield of rice and wheat increased by applying potash fertilizer from different sources. The yield of rice increased by the increases of spikes/bin2 and filled grains/spike, the yield of wheat was increased by the increase of spikes/hm^2, grains/spike and weight of grain. The content of available K was increased by applying potash fertilizer from different sources, especially by applying chemical potash fertilizer.
