摘要
为了研究不同喷雾助剂和喷头对玉米田常用除草剂烟嘧·莠去津防除效果的影响,在自走式喷杆喷雾机施药过程中,选择不用型号喷头(XR11001、XR110015、XR11002)、不同助剂(2、3、4号喷雾助剂),调查药后14 d玉米田杂草株防效以及药后28 d玉米田杂草株防效和鲜重防效,并调查对玉米的安全性和玉米的产量。结果表明:自走式喷杆喷雾机施药过程中,选择喷头XR11001、4号助剂的杂草防效要优于其他处理组,且对玉米安全,不会影响玉米产量。自走式喷杆喷雾机施药的效果要优于人工喷雾。自走式喷杆喷雾机施药过程中,选择细喷头和合适的喷雾助剂,能有效提高药效。
The efficacy of the mixture of nicosulfuron·atrazine in corn with the addition of spray adjvants(No.2,No.3,No.4)and using different nozzles(XR11001,XR110015,XR11002)was visually evaluated at 14 and 28 days and by weed fresh weight determinations at 28 days after application using a self-propelled sprayer.Crop selectivity and corn yield were also investigated.Weed control efficacy obtained with the self-propelled sprayer equipped with XR11001 nozzles and using No.4 adjvant was better than other treatments.The optimal combination was selective to corn and did not affect crop yield.The self-propelled sprayer was more effective than a manual spray,which could geatly improve the pesticide efficacy when selecting a fine nozzle and appropriate adjvant.
