| 中文摘要:为了探索马铃薯早晚疫病的减药防控技术，以马铃薯品种‘新大坪’为材料，选择植物免疫诱抗剂阿泰灵、中药类叶面处理剂禾奇正和香芹酚、植物调节剂芸苔素内酯、氯化胆碱及微量元素类叶面肥等，分别于马铃薯苗期、花期、团颗期进行叶面喷施，研究各叶面处理剂对马铃薯早晚疫病防控及产量提升效果。结果显示，9种处理剂对马铃薯早疫病和晚疫病均有一定的防控效果，并能促进马铃薯增产。其中香芹酚、阿泰灵、芸苔素内酯和禾奇正防控和增产效果最高，对马铃薯早疫病防控效果为34.29%~42.25%，对马铃薯晚疫病的防控效果为31.21%~47.78%，增产率为12.68%~17.21%。 |

| Abstract:In order to explore the technology of application reducing of fungicides to prevent and control potato early and late blight.The potato cultivar ‘Xindaping’ was used as experimental material, the spraying plant immune inducer Artalin,Chinese herbal foliar treatment agents Heqizheng and Carvone,plant regulators Brassinolide and Choline chloride,and micro element foliar fertilizer were selected to spray on the leaves of potato at seedling,flowering and rosette stages,the effects of different foliar treatment agents on the prevention and control of potato early and late blight and yield improvement were evaluated.The results showed that nine kinds of foliar treatment agents had good control efficiency against potato early and late blight,and could increase potato yield. Carvonol,Artelin,Brassinolide and Heqizheng had the highest effect against potato early and late blight and the yield-increasing,its control efficiency was 34.29%-42.25% and 31.21%-47.78%,respectively,and increase rate was 12.68%-17.21%. |
