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。 According to the investigation and data analysis of wheat sheath blight in Suqian City in 1999, it is concluded that the main relapse factors affecting wheat sheath blight are mainly the warm winter climate, the disease resistance of the main cultivars is poor, the sowing period is early, the amount of fertilization is large and the technique of application is backward . According to the experimental study, it is proposed that the prevention and control measures should be integrated with late-stage sowing, promotion of semi-winter wheat varieties with strong disease resistance and prevention and treatment measures such as “mixing two sprays”, increasing the dosage and amount of water and premature rhythm.
