| 摘 要： | 针对马铃薯晚疫病的不同发生级别开展了拔秧处理防治晚疫病的试验研究，结果表明：随着拔秧时间的延后，马铃薯的产量、大中薯率、块茎淀粉含量均有增加的趋势；所有拔秧处理与对照相比，烂薯率均有所下降，但拔秧时期不同，烂薯率和防效也不相同，当晚疫病为0～2级时，拔秧对晚疫病的防治效果较好，而达到3级以后，防病效果比较差．

| Abstract: | To prevent and control the photato late blight in different grades, the method of pulling up seedling was selected. The results showed that the yield, rate of trading potato, and starch content of tuber had increasing trend along with the delaying seedling pulling. The rate of rot potato in any treatment was decreased than contrast, but the rate of rot potato and controlling effects of potato late blight were also different. The effects were good when the late blight diseased seedling was pulled during the 0-2 grade. But in grade 3,the effects were bad. |
