摘要/Abstract

摘要： 为明确不同化学药剂种类及用量在马铃薯种薯浸种条件下对马铃薯块茎晚疫病防治效果和商品薯产量的影响,试验以大西洋为供试品种,选用安克、克露和甲霜灵锰锌3种药剂的350倍、500倍2个浓度药液分别浸种,综合分析不同药剂种类及用量处理对马铃薯块茎晚疫病的防治效果、中薯和大薯的产量、马铃薯总产量以及贮存发病率影响的差异性。结果表明:50%安克可湿性粉剂350倍药液浸种处理的晚疫病防治效果最好,其发病率最低,为5.49%,比对照降低了20.32百分点,块茎产量最高,为29.57t/hm2,贮藏期间烂薯率最低,为3.64%,比对照减少了13.97百分点。综合分析得出:马铃薯生产过程中以50%安克可湿性粉剂稀释350倍浓度处理较为适用。

Abstract: This study was conducted in order to clarify the effects of different chemical agents and dosages on potato tuber late blight control and commercial potato yield under soaking conditions of potato seed potatoes.In this experiment,Atlantic Ocean was used as the tested variety,and the extracts of Anke,Kelu and Metalaxyl Mn-Zn were used diluted at 350 times and 500 times of the two kinds of medicinal solutions to soak seeds,and comprehensive analysis of different types and dosages of potato stalk late blight was carried out.The effects of prevention and control on the yield of medium potato and large potato,total potato yield and storage morbidity were all significant.The results showed that the 50%Anke wettable powder was the best in treatment of late blight.With its use,the incidence rate was 5.49%,the control effect was increased by 20.32 compared with the control,the highest yield of tubers was 29.57 t/hm2,and the rate of rotten potatoes during storage was the lowest at 3.64%,which was 13.97 percentage points lower than the control.According to the comprehensive analysis,it is more suitable to use the 50%Anke wettable powder diluted by 350 times in the potato production process.
