摘要：

根据温州市1990-2014年细菌性条斑病发生的历史资料，应用通径分析方法，分析了温州市晚稻细菌性条斑病发生程度与发病时间、雨日、雨量、相对湿度、平均气温之间的关系。结果显示，影响晚稻细菌性条斑病发病程度最大的因子是发病时间，雨日、雨量、平均气温、相对湿度对发病程度直接作用较小，但在始发病时间早的情况下，明显促进了细菌性条斑病的发生。

Abstract:

Basis on historical information in Wenzhou during 1990-2014, the relationship between the incidence of bacterial leaf streak and occurrence time, wet days, rainfall amount, relative humidity, average temperature were conducted by approach of path analysis. The results showed that occurrence time was the greatest factor influencing the incidence of bacterial leaf streak, and other factors would promoted the bacterial leaf streak incidence when the disease broken out early.

Key words: rice, bacterial leaf streak, incidence, meteorological factors, path analysis
