摘要/Abstract

摘要： 为了筛选出防除阔叶杂草高效安全的胡麻化学除草剂,试验用30%苯唑草酮SC等5种除草剂、30%苯唑草酮SC180mL/hm2+48%灭草松AS2250mL/hm2等7种混用组合,在苗期实施茎叶喷雾,开展防除胡麻阔叶杂草试验。结果表明:有2个混用组合对胡麻阔叶杂草防效优良,30%苯唑草酮SC180mL/hm2+15%噻吩磺隆WP225g/hm2株防效和鲜重防效分别达到90.63%,77.50%,48%灭草松AS2250mL/hm2+15%噻吩磺隆WP300g/hm2株防效和鲜重防效分别达到88.54%,92.50%,喷药后7d胡麻恢复生长,对胡麻生长安全。这2个混用组合防治效果好、对胡麻生长安全、用药成本低,并且提高了胡麻产量,适宜大面积推广应用。

Abstract: For screening high-efficient and safe broadleaf weeds herbicides in flax fields,this study carried out application tests of 5 herbicides including 30%topramezone SC and 7 mixtures including 30%topramezone SC 180 mL/hm2+48%Bentazone AS 2 250 mL/hm2 by spraying on stems and leaves of flax seedlings.The results showed that 2 mixtures had excellent control effects on broadleaf weeds in flax fields.The plant and fresh weight control effects of 30%topramezone SC 180 mL/hm2+15%thifensulfuron methyl WP 225 g/hm2 were 90.63%and 77.50%,respectively.The plant and fresh weight control effects of 48%Bentazone AS 2 250 mL/hm2+15%thifensulfuron methyl WP 300 g/hm2 were 88.54%and 92.88%,respectively.The flax resumed growth after spraying 7 days and the 2 mixtures were safe for flax growth.In summary,the two mixtures had excellent control effects on broadleaf weeds.They were cheap and significantly increased the yield of flax so they should be popularized and applied in flax production.
