摘要
为了探讨‘激健’在直播稻田控害除草、农药减量的作用效果,针对常德水稻主产区的主要草害,2016年开展了应用‘激健’减量控害水稻直播稻田除草试验与示范研究。结果表明,应用‘激健’可以显著减少除草剂用量,促进直播稻田水稻产量的提高,其中以添加‘激健’0.225 kg/hm^2、除草剂减量20%处理的控草与增产效果最佳,与对照比较,大区试验水稻增产达16.6%,小区试验增产达23.5%。
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 significantly 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/hm^2 and herbicides reduced 20% applied rate,which increased yield 16. 6% in the wide field trial and 23. 5% in the plot experiment.
