苯噻酰草胺·乙氧磺隆防除水稻直播田杂草的效果及对光照和养分的影响
Effect of mefenacet·ethoxysulfuron on weed control,nutrient,light intensity and rice yield in paddy field
摘要
Abstract
The effect of 70% mefenacet·ethoxysulfuron WDG on weed control in paddy field was studied .The rice yield ,light intensity ,the content of N‐P‐K and water were also analyzed after weed control by mefenacet·ethoxysulfu‐ron .The results indicated that the efficacy of weed control were remarkable by 70% mefenacet·ethoxysulfuron WDG in paddy field .The control efficacy on Echinochloa crusgalli ,Cyperus dif formis ,Monochoria vaginalis and Eclipta prostrate was ranged from 85.9 to 100% .The light intensity ,water and fertilizer were greatly improved after weed control .The rice yield was ranged 5 080.24 to 5 253.49 kg·hm-2 after treated with mefenacet·ethoxysulfuron ,which increased by 72.7% ~78.6% compared to untreated control .Moreover ,the yield income increased by 5 560.91 ~6 011.36 Yuan·hm -2.关键词
