高纬度花生叶部病害防治技术研究

Studies on Prevention and Control Technology of Peanut Leaf Disease at High Latitudes

[目的]系统研究高纬度地区花生叶部病害防治技术。[方法]在田间试验条件下,以泉花551花生品种为材料,选取12种杀菌剂,以清水和多菌灵作对照,研究其对花生叶斑病的防治效果。[结果]13种杀菌剂对叶斑病均有防治效果,其中百泰、阿米妙收、凯润和外尔(用药量:750.0 m L/hm2、187.5 m L/hm2、300.0 m L/hm2和375.0 m L/hm2)的防治效果较好,分别较多菌灵提高49.27、35.73、32.22和26.00个百分点;其产量均在5250.00 kg/hm2以上,分别较清水增产15.63%、11.84%、10.44%和16.82%,较多菌灵增产13.79%、10.07%、8.69%和14.96%,且安全性高。[结论]为高纬度地区花生叶部病害防治提供了参考。

The aim was to systematically study the prevention and control technology of peanut leaf diseaseat high latitudes. Under field conditions, setting water and carbendazim as control, Quanhua 551 was used to studythe control effect of 12 kinds of fungicides on peanut leaf spot. Results showed that 13 kinds of fungicides had pre-ventive effect against leaf spot disease, and Baitai, A-mimiaoshou, Kairun and Waier at 750.0 m L/hm^2, 187.5 m L/hm^2, 300.0 m L/hm^2 and 375.0 m L/hm^2 were better than others, which increased by 49.27%, 35.73%, 32.22% and26.00% compared with carbendazim. Their yield were more than 5250 kg//hm^2, which were 15.63%, 11.84%,10.44% and 16.82% more than the water control, and 13.79%, 10.07%, 8.69% and 14.96% more than carbendazimtreatment. Also, they were safer. The results provided reference for prevention and control of peanut leaf diseaseat high latitudes.
