| 摘 要： | 针对春油菜病害防控及产量提升,选择阿泰灵、禾奇正等9种不同叶面处理剂,分别在春油菜蕾薹期、初花期、花荚期喷施1次,综合春油菜生理指标、产量、病害防效分析,结果表明,禾奇正、阿泰灵和芸苔素内酯可降低春油菜株高、增加春油菜茎粗、提高春油菜产量,增产率分别为12.42%、8.48%和6.54%,并对春油菜白粉病和菌核病有显著的防控效果,对白粉病的防效为31.15%～51.04%,对菌核病的防效为27.96%～41.14%。

| Abstract: | Aiming at prevention and control of spring rape diseases and yield improvement,nine different foliar treatments,such as Atailing and Heqizheng,were selected and sprayed once at bud stage,early flowering stage and flower pod stage of spring rapee,respectively. The physiological indexes,yield and disease prevention of spring rape were comprehensive. The results showed that Heqizheng,Altailing and Brassinolide could reduce the plant height,increase the stem diameter and yield of spring rape by 12.42%,8.48%,and 6.54%,respectively. It has significant control effects on powdery mildew and sclerotinia disease in spring rape. The control effect against powdery mildew is between 31.15% and 51.04%,and the control effect against sclerotinia is between 27.96% and 41.14%. |
