摘要:

【目的】筛选对大麦田阔叶杂草具有较好防效的除草剂,为荒漠绿洲生态区安全高效应用除草剂提供依据。【方法】采用随机区组的方法,调查各药剂处理小区的杂草株数和地上部分鲜质量,评价供试药剂对大麦田阔叶杂草的防除效果及安全性。【结果】药后50 d,20%双氟·氟氯酯WG 19.50 g/hm2、10%双唑草酮OD 37.50 g/hm2、200 g/L氯氟吡氧乙酸EC 210.00 g/hm2、22%氟吡·双唑酮OD 165.00 g/hm2、50% 2甲·氯·双氟SC 450.00 g/hm2、87.5% 2,4-滴异辛酯EC 577.50 g/hm2、25%辛酰溴苯腈EC 562.50 g/hm2和75%苯磺隆WG 22.50 g/hm2对阔叶杂草灰绿藜和卷茎蓼的株防效和鲜质量防效较好,防效分别为90.87%~96.02%和94.15%~98.08%,各处理株防效和鲜质量防效之间均无显著性差异。【结论】20%双氟·氟氯酯WG、10%双唑草酮OD、200 g/L氯氟吡氧乙酸EC、22%氟吡·双唑酮OD、50% 2甲·氯·双氟SC、87.5% 2,4-滴异辛酯EC、25%辛酰溴苯腈EC和75%苯磺隆WG可防除大麦田灰绿藜、卷茎蓼等阔叶杂草,且对大麦生长安全,可在大田合理轮换使用。

Abstract:

【Objective】 The purpose of this study is to screen herbicides with good efficacy against broadleaf weeds in barley fields and provide a basis for safe and efficient application of herbicides in desert oasis ecological zones. 【Methods】 A randomized block design was conducted to this study and the number of weed plants and the fresh mass of above-ground parts in each treatment plot were investigated to evaluate the effectiveness of the test agents on broadleaf weeds and the safety of the barley plants in barley fields. 【Results】 50 d after herbicides application,20% florasulam- halauxifen-methyl WG 19.50 g/hm2,10% bipyrazone OD 37.50 g/hm2,200 g/L fluroxypyr EC 210.00 g/hm2,22% bipyrazone-fluroxypyr 165.00 g/hm2,50% MCPA-isooctyl-fluroxypyr-florasulam SC 450.00 g/hm2,87.5% 2,4-D isooctyl ester EC 577.50 g/hm2,25% bormoxynil octanoate EC 562.50 g/hm2 and 75% tribenuron methyl WG 22.50 g/hm2 all had great control effects of the quantity and fresh weight of weeds on Chenopodium glaucum with the range from 90.87% to 96.02% and on Fallopia convolvulus with the range from 94.15% to 98.08%. There was no significant difference between the treatment strains and fresh quality. 【Conclusion】 20% florasulam- halauxifen-methyl WG,10% bipyrazone OD,200 g/L fluroxypyr EC,22% bipyrazone-fluroxypyr OD,50% MCPA-isooctyl-fluroxypyr-florasulam SC,87.5% 2,4-D isooctyl ester EC,25% bormoxynil octanoate EC and 75% tribenuron methyl WG have the capability to control broadleaf weeds like Chenopodium glaucum and Polygonum capitatum in barley fields,and it is safe for barley growth and can be used in reasonable rotation in barley fields.
