摘要
通过对1999年宿迁市小麦纹枯病大发生调查及多年资料分析,认为影响小麦纹枯病重发因素主要是暖冬气候、主栽品种抗病性差、播种期早、施肥量大和施用技术落后等。据试验研究提出防治对策是综合采用适期迟播、推广半冬性抗病强的小麦品种以及药剂防治中采取“一拌两喷”、加大药量及水量、适期早治等措施。
Investigating the occurrence of wheat sheath blight in 1999 and analyzing several years' data, the result shows that the main causes of serious occurrence of wheat sheath blight is as following: warm winter, disease resistance of main wheat varieties, early sowing, heavy dressing and backward fertilizer application.Based on the experiments, it suggested that we can use integrate measures such as sowing later at optimum period, extending half winter with high resistance wheat varieties, taking chemical control measures such as “applying seed treatment once and spraying chemicals twice”, using more fungicide and water and controlling at optimum period.
