怎样给小麦施钾肥近年来，随着小麦产量的大幅度提高，土壤含钾量已呈逐年下降趋势，不少麦田缺钾现象日趋明显。为此，合理施用钾肥已成为实现小麦高产稳产的一项重要技术措施。据１９８８～１９９３年３３个小麦钾肥试验结果证明：在亩施４～５公斤钾肥（氧化钾）的基础...
How to apply potassium fertilizer to wheat In recent years, with the substantial increase of wheat yield, the potassium content of soil has been declining year by year, and many wheat fields are becoming more and more deficient in potassium. Therefore, the rational application of potash fertilizer has become an important technical measure to achieve high and stable yield of wheat. According to the results of 33 wheat potassium tests from 1988 to 1993, it was proved that the basis of 4 to 5 kg of potassium fertilizer (potassium oxide)
