摘  要：
试验研究了不同钾肥施用量与玉米茎腐病发生的关系及种衣剂结合增施钾肥对茎腐病的防治效果。结果表明:增施钾肥可增强植株的抗性,降低玉米茎腐病的发病率。随着钾肥施用量的增加,玉米茎腐病的发病率逐渐降低,而对玉米茎腐病的防治效果逐渐提高。以钾肥施用量150kg hm2防治效果最好,质量分数为2 5%适乐时悬浮种衣剂与钾肥150kg hm2结合施用对玉米茎腐病防效达87 40%。

摘  要：
The relationship between different application amounts of potash fertilizer and the incidence of corn stalk rot was studied. Together studied was the control effect of combining seed coating and an increased amount of potash fertilizer on corn stalk sot. The results showed that the application of an increased amount of potash fertilizer increased plant resistance, and decreased the incidence of corn stalk rot. With the increase of the amount of potash fertilizer, the control effect on corn stalk sot gradually increased. The best control effect reached when the application amount of potash fertilizer was 150　kg/hm~2. The control effect of combining 2.5% celest seed coating with potash fertilizer 150　kg/hm~2 was 87.4%.
