直播稻田应用‘激健’减量控害除草效果初探
Preliminary Study on the Effect of 'Jijian' to Reduce Herbicide Rate and Control Weed in Direct Seeded Paddy
摘要
Abstract
In order to investigate the effect of‘ Jijian'to reduce herbicide rate and control weeding in direct seeded paddy,experiment was carried out in the key rice cultivation areas in Changde of Hunan province of China during 2016.The result showed that ‘Jijian'application could significandy controlled Echinochloa crusgall (L.) Beauv,Leptochloa chinensis (L.),Monochoria vaginalis (Burm.f.) Presl and Cyperus difformis (L.),and reduced herbicide applied rate and accelerated the yield of the direct seeded paddy.The best effect of all treatments was the treatment with ‘Jijian'0.225 kg/h2 and herbicides reduced 20％ applied rate,which increased yield 16.6％ in the wide field trial and 23.5％ in the plot experiment.关键词
