摘要: 【目的】 研究除草剂添加助剂减量施用对核桃-小麦间作模式下麦田阔叶杂草的防除效果及安全性,为麦田除草剂减量施用提供科学依据。【方法】 采用随机区组的方法,定点取样调查各处理的杂草株数、鲜质量,评价除草剂减施对冬麦田杂草的防除效果及对小麦的安全性。【结果】 药后45 d,6%双氟·唑草酮OD减施30.00%及其减施30.00%+助剂'激健、20%双氟·氟氯酯WG减施30.00%及其减施30.00%+助剂激健、10%苯磺隆WP减施30.00%及其减施30.00%+助剂激健对核桃-小麦间作麦田阔叶杂草的株防效和鲜质量防效分别为92.33%~97.97%和98.78%~99.57%,且对小麦安全,无药害。【结论】 6%双氟·唑草酮OD、20%双氟·氟氯酯WG和10%苯磺隆WP减施30.00%可有效防核桃-小麦间作麦田播娘蒿、灰绿藜等阔叶杂草,且对小麦生长安全,可在大田合理轮换使用。

Abstract: 【Objective】 In order to explore the control effect and safety of herbicide adding synergist on broadleaf weeds in walnut-wheat intercropping field, this paper aims to perform related experiments to provide scientific basis for herbicide reducing application in wheat field.【Method】 Randomized block design was used to research the number and the fresh weight of weeds at fixed spots, and the effect of herbicide reduced application on weeds and safety to winter wheat was evaluated.【Result】 After forty-five days, under the condition of the dosage of 30.00% reduced, the control effect of 2% florasulam + 4% carfentrazone-ethyl OD, 10% halauxifen - methyl + 10% florasulam WG and 10% tribenuron - methyl WP added synergist 'Jijian' on broadleaf weeds were 92.33% - 97.97% and 98.78% - 99.57%, respectively. All the treatments did not negatively influence on the growth and development of the winter wheat.【Conclusion】 6% difluorocarbon OD, 20% difluorocarbon WG and 10% tribenuron methyl WP can effectively control broadleaf weeds such as Descuminia sophia and Chenopodium glaucum in walnut wheat intercropping field. They are safe for the growth of winter wheat and can be used in field alternation reasonably.

Key words: walnut-wheat intercropping; winter wheat field; broadleaf weeds; herbicide reduction; efficacy evaluation
