| 中文摘要: |
| 2012年在惠州会达菜场以除草剂（直播净、秧歌和丁草胺）为主处理、施用方法（土壤处理、幼苗处理和综合处理）为副处理进行了一季中晚稻旱直播田化学除草研究。结果表明：在土壤湿润的条件下，播种后当天或第2 d每667 m2用80 g直播净（主要成分为36%丙草胺+4%苄嘧磺隆）兑水50 kg 喷施或用200 g秧歌（23.9%丁草胺+1.1%苄嘧磺隆）混细砂15 kg 撒施, 可有效控制一季中晚稻旱直播田的草害。 |
| 英文摘要: |
| In this paper the field experimentation was conducted during in 2012 in Huida Farm, Huizhou County, Guangdong Province. The main treatment is herbicide (Pretilachlor + Bensulfuron-methyl, Yangguo and Butachlor), the sub-treatment is application method (soil treatments,seedling treatment and integrated treatment). Results of investigation showed that under the soil moist conditions two methods can significantly controlled weed when were applied at 1 or 2 days after the seeding. one which 80 g of 36% Pretilachlor+4% Bensulfuron-methyl deluted to 50 kg of water was sprayed on the leaves of the weed per 667 m2; another which 200 g of 23.9% Butachlor
+1.1% Bensulfuron-methyl mixed with 15 kg of sandy soil were applied on the pad per 667 m2. |
