[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。
[Objective] The research aimed to systematically study the prevention and control of peanut leaf diseases in high latitudes. [Method] Under the field experiment conditions, 12 kinds of fungicides were selected from the spring peanut variety Quanhua 551 as the control, and the control effect on peanut leaf spot was studied with water and carbendazim as control. [Result] Thirteen kinds of fungicides had control effects on leaf spot disease. Among them, 100 Thai, Ami Miao, Kai Run and Seoul (dosage: 750.0 m L / hm2, 187.5 m L / hm2, 300.0 m L / hm2 and 375.0 m L / hm2, respectively, which were respectively 49.27, 35.73, 32.22 and 26.00 percentage points higher than that of carbendazim respectively. The yield of all the bacteria was above 5250.00 kg / hm2, which increased 15.63% and 11.84% 10.44% and 16.82% respectively, which increased the yield by 13.79%, 10.07%, 8.69% and 14.96% more than the other fungi. [Conclusion] This provided references for the prevention and control of peanut leaf diseases in high latitudes.
