摘要
1988年以来长江中下游麦区小麦赤霉病发生频率及严重程度均有所减轻。针对这一现象,作者调查分析了1960～2000年的有关气象资料、相关年份江苏省小麦新品种区域试验结果及扬州地区小麦大面积生产情况。初步认为,近10多年来长江中下游麦区赤霉病流行程度减轻,虽受气候条件的影响,但主要原因是推广抗赤霉病小麦品种,其次是采用药剂防治的结果。
The occurring frequency and severity of wheat scab have been alleviated in the wheat region of the middle and lower valley of Yangtze River since 1988. To this appearance, authors investigated and analyzed the relevant meteorological data of Yangzhou from 1960～2000, the statistical data of regional trial for new wheat variety of Jiangsu province in correlative years and data of wheat production in Yangzhou. It was preliminarily indicated that:in the recent 10 year, though the alleviation of the Epidemic incidence of wheat scab was affected to the climate in the wheat region of the middle and lower valley of Yangtze River, but the main factor was the spreading of wheat variety with resistance to scab, the secondary factor was chemical control.
