| 于2014年水稻生长季选择10种常用的水稻直播田除草剂在安徽省马鞍山市当涂县水稻田进行田间试验, 研究不同时期施用不同除草剂对直播稻田杂草的防除效果及对水稻产量和安全性的影响。结果表明:水稻5叶1心时施用11%噁唑·五氟磺可分散油悬浮剂、水稻3叶1心时施用21%苄·五氟·氰氟草油悬浮剂和6%五氟·氰氟草可分散油悬浮剂均可高效防除直播稻田禾本科杂草、莎草科杂草和阔叶杂草, 总草株防效和鲜重防效均在90%以上。测产结果表明, 以上3种药剂对水稻的增产率较高, 分别为22.4%、22.1%和21.7%。3种药剂在水稻生长期施用没有产生药害, 起到了稳产、增收的作用。 |

| In order to screen the suitable herbicide used in direct-planting rice field at Dangtu County, Ma’anshan City, Anhui Province, ten kinds of herbicides were chosen to investigate their control effects on weeds and safety on crop during rice growing season in 2014. The results showed that application of 11% metamifop·penoxsulam dispersed OF at 5-leaf stage of rice, 21% bensulfuron-methyl·penoxsulam·cyhalofop-butyl OF or 6% penoxsulam·cyhalofop-butyl OF at 3-leaf stage of rice, respectively, controlled weeds effectively. And the control efficacies based on the plant numbers and fresh weight for whole weeds were both above 90%. All the three herbicides increased the rice yields by 22.4%、22.1% and 21.7%, respectively, compared to the control and showed no damage to rice. |
