摘要:
为探究除草剂防除效果，研究了25%砜嘧磺隆水分散粒剂对马铃薯田杂草的防除效果以及对其生长安全性和产量的影响。结果表明：25%砜嘧磺隆WDG在有效成分用量为75、80、90 g?hm-2施药后45 d对一年生禾本科杂草稗草、谷莠及阔叶科杂草鸭跖草、藜、酸模叶蓼的平均鲜重防治效果分别为76.72%、82.40%、85.70%，均有较好的防治效果。不同浓度25%砜嘧磺隆WDG的施用均使马铃薯产量增加显著，增产率分别为6.07%、9.30%、10.86%。25%砜嘧磺隆WDG在使用剂量下于杂草苗后2~5叶期进行茎叶喷雾处理对马铃薯安全，未见药害发生，试验剂量下各处理对马铃薯生长均无不良影响，除草效果好，具有一定的增产作用，可以作为马铃薯田的主要除草剂进行使用。
Abstract:
To explore the effect of herbicide prevention，the effect of 25% rimsulfuron WDG on the weed control in potato field and its effect on the growth safety and yield of potato were studied.The results showed that 45 days after the applying pesticid,25% rimsulfuron WDG had better control effect by rimsulfuron dosage of 70,80 and 90 g?hm-2,and the average fresh weight control effect of Echinochloa crusgalli,Setairaviridis,Commelina communis,Chenopodium,and Polygonum sibiricum was 76.72%,82.40% and 85.70%.Potato yield increased significantly in three concentrations of 25% rimsulfuron WDG,the yield increasing rate was 6.07%,9.30%,10.86%.It was safety and no phytotoxicity for potato by 25% rimsulfuron WDG was used after plant 2~5 leaf stage.25% rimsulfuron WDG was no adverse effects on potato growth,had better weed control effect,played a certain role in the promotion of the potato yield increase which can be used as the main herbicide potato field.
