把我省小麦纹枯病区域分布状况与土壤中速效钾含量区域分布状况进行了比较，两者间具有明显的相关性。土壤增施钾肥试验结果表明，增施钾肥能明显控制小麦纹枯病的发生，表明小麦纹枯病的区域分布与土壤中钾素含量有关。
The distribution of wheat sheath blight in our province was compared with the distribution of available potassium in the soil. There was a clear correlation between them. The results of soil application of potash fertilizer showed that the application of potash fertilizer could significantly control the occurrence of wheat sheath blight, indicating that the distribution of wheat sheath blight was related to the content of potassium in the soil.
