| 摘 要： | 在明确了5月中下旬与6月中下旬降雨量对向日葵锈病流行的作用基础之上,进一步研究表明病菌的初始菌量也是影响病害流行程度的一个重要因子。向日葵锈病的年度流行主要由环境因素和越冬后的初始菌量两者共同影响的。初始菌量由上年病害发生程度作出估计。据此可作病害流行程度的中期或长期预报。

| Abstract: | It was shown that precipitation in May and June was a factors affecting sunflower rust progress.The further study showed that the amount of overwinter teleospore was also an important factor governing sunflower rust epidemic outbreak The sunflower rust epidemic was actually effected by the environmental factors and inocula.According to this theory we can make mediate or long term prediction of sunflower rust disease progress. |
