小麦赤霉病、油菜菌核病是我县旱季作物上的主要病害,笔者在我站1980~1990年测报调查资料中发现,小麦赤霉病与油菜菌核病的发病程度之间有极密切关系。我县1980~1990年油菜菌核病发病程度分别为1,1,1,2,2,3,2,3,1,3,5级;小麦赤霉病发病程度分别为1,1,1,3,3,4,2,3,1,2,5级.从中可见,11年中两病的发病程度有7年完全相同,另外4年也只是上下波动一级。具体归纳为:当油菜菌核病发病程度为1级年份,小麦赤霉病发病程度均为1级;油菜菌核病发病程度为2
Wheat scab, Sclerotinia sclerotiorum is the main disease on the dry season crops in our county. According to the survey data from 1980 to 1990 in our station, there is a close relationship between the incidence of scab and Sclerotinia sclerotiorum relationship. The incidence of Sclerotinia sclerotiorum in our county from 1980 to 1990 were 1,1,1,2,2,3,2,3,1,3 and 5, respectively. The incidence of scab in wheat was 1,1,1 3, 3, 4, 2, 3, 1, 2, and 5. It can be seen that the incidence of these two diseases was exactly the same in seven years in 11 years, and the other four years were only fluctuating up and down. Specific summarized as follows: when the incidence of sclerotinia sclerotiorum is grade 1, the incidence of scab is 1, and the incidence of sclerotinia sclerotiorum is 2
