| 摘 要： | 以四川资中为例,分析了21年小麦赤霉病的发生规律,同时通过对气象因子的主成分分析,提取了与该病发生关联度较大的气象因子,并将其对小麦赤霉病发生的影响进行了分析。结果表明：21年来资中小麦赤霉病的发生情况较严重,其中最严重的是2000年,1996年次之,病穗率都超过16%。3月下旬～4月中旬的降水量、温度、相对湿度以及前一年秋季的降水和冬季的温度在不同程度上影响小麦赤霉病的发生。最后,提出了防治小麦赤霉病发生的相关措施。

| Abstract: | The rules of wheat scab was analyzed based on 21 years data of Zizhong,Sichuan.Using the principal component analysis of meteorological factors,several meteorological factors with highly correlation with the disease occurrence were selected.Their impacts of the wheat scab occurrence were studied.The results showed that the incidence of wheat scab in Zizhong was very serious during 21 years,and the worst year was 2000,followed by 1996.Both of their sick spike rate exceeded 16%.From late April to mid-March's ... |
