除草剂减量配施增效助剂对杂草防效和春小麦产量的影响
Effects of Herbicide Reduction Combined with Efficacy-Enhancing Adjuvants on Weed Control Effect and Spring Wheat Yield
摘要
Abstract
In order to promote the prevention and control of pesticide reduction and green production of spring wheat grass in the western region of Heilongjiang Province,Kechun 9 was used as the experimental material.Through field experiments conducted in the Keshan Counry,in 2022,the impact of reduced herbicide dosages combined with efficacy-enhancing adjuvants on weed control in wheat fields,wheat yield,and yield traits was studied.The results indicated that,treatment 2(20％reduction in herbicide usage combined with efficacy-enhancing adjuvants Jijian)and treatment 3(40％reduction in herbicide usage combined with efficacy-enhancing adjuvants Jijian)produced effective weed control,achieving the highest plant control effectiveness and fresh weight control effectiveness,respectively.The highest yield of 5 567.22 kg·ha-1 was recorded in the treatment of 40％reduction with vigorous stimulant,achieving results comparable to conventional dosages.Under this treatments,the number of effective spikes and 1000-grain weight were 519.33 spikes·ha-1 and 32.82 g,with the lowest number of sterile spikes at 0.23,showing no difference from the 20％reduction mixed with vigorous stimulant and conventional treatments.However,significant differences were noted compared to the other two treatments.Correlation analysis showed that spike number,herbicide dosage and 1000-grain weight played a facilitating role in the wheat yield,while the sterile spike number had a significant negative effect.Therefore,the recommended best practice for weed control in this region's wheat fields is a 40％reduction in herbicides combined with the use of the effcacy-enhancing adjuvants Jijian.关键词
