摘要:
为探究除草剂防除效果，研究了96%精异丙甲草胺乳油（EC）对马铃薯田一年生杂草的防除效果、马铃薯生长的安全性及产量的影响。结果表明：96%精异丙甲草胺EC在有效成分用量为750、975、1 200 mL?hm-2施药后45 d对一年生禾本科杂草稗草、谷莠和一年生阔叶杂草苘麻、鸭跖草的平均鲜重防治效果分别为76.06%、82.13%、85.28%，防治效果较好。对马铃薯产量有所增加，增产率分别为2.80%、4.50%、7.10%。96%精异丙甲草胺EC在使用剂量下于播后苗前进行土壤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，从经济、有效和安全等方面综合考虑可以作为马铃薯田的主要除草剂进行推广与使用。
Abstract:
To explore the effect of herbicide prevention，the effect of 96% (S)-Metolachlor EC 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,96% (S)-Metolachlor EC had better control effect by (S)-Metolachlor dosage of 750,975 and 1 200 mL?hm-2,and the average fresh weight control effect of Echinochloa crusgalli,etaira viridis,Commelina communis and Abutilon theophrasti was 76.06%,83.13% and 85.28%.Potato yield increased significantly in three concentrations of 96% (S)-Metolachlor EC,the yield increasing rate was 2.80%,4.50%,7.10%.It was safety and no phytotoxicity for potato by 96% (S)-Metolachlor EC was used before emergence after seeding.96%(S)-Metolachlor EC was no adverse effects on potato growth,had better weed control effect,played a certain role in the promotion of the potato yield increase,in terms of economic efficiency and safety which can be used as the main herbicide potato field.
