摘　　要：【目的】姜瘟病的发生与降雨量、降雨持续天数、温度有密切关系,提前做好雨季到来前预测预报对姜瘟病的防控很有必要。【方法】采用实地调查法,调查了山东省生姜主产区姜瘟病病株出现的时间、发病高峰与降雨量、降雨天数及温度的变化关系。【结果】山东地区,姜瘟病首次出现的时间是6月下旬至7月上旬,温度24.1~26.8℃,7天至9.5天内降雨量达136.1~207.7 mm;姜瘟病高峰出现时间是7月中旬至9月中旬,7月至9月总降雨量为400~598 mm,降雨总天数为29~34 d。【结论】姜瘟病开始发病时日均温20℃左右,发生的最适宜温度为25~30℃,当温度满足了姜瘟发生的条件后,降雨成为姜瘟发生的首要条件。山东地区,6月下旬雨量逐渐增多,姜瘟病开始出现。从7月份开始,雨量、温度、降雨天数达到了姜瘟病大量爆发的条件,从7月下旬逐渐进入了姜瘟发病高峰。而进入9月后,温度、雨量均趋下降趋势,姜瘟发病率逐渐降低。为此,山东地区应于6月下旬做好姜瘟病的预防。[Purpose]The occurrence time of bacterial wilt of ginger,the peak of disease,rainfalls,rainfall days and temperature were investigated at the main areas of ginger planting in Shandong Province,because the occurrence of bacterial wilt of ginger is closely related to rainfalls,rainfall duration and temperature.[Methods]The field survey method is adopted,the relationship between the occurrence time,peak of disease,rainfall,rainfall days and temperature of ginger blast in Shandong Province was investigated.[Findings]The results of the survey indicated that it was in late June to early July,and temperature was 24.1℃to 26.8℃,and rainfalls amounted to 136.1 mm to 207.7 mm within 7 to 9.5 days when the bacterial wilt of ginger occurred.And it was from midJuly to midSeptember when the peak of bacterial wilt of ginger occurred,and the total rainfall was 400 mm to 598 mm from July to September,and total rainfall days were 29 to 34 days.[Conclusions]So,the prevention of bacterial wilt of ginger should be done well in late June.
