2016年江苏南通等地区中晚粳水稻栽培方式仍呈多样化,直播稻、机插秧、手栽稻并存。直播稻田生态环境十分有利于杂草生长,机插秧移栽时由于秧龄较小,对除草剂的安全性要求较高。化学除草是控制草害、夺取水稻高产的重要措施,各地要根据当地水稻栽培方式和草情草相,做好分类指导,选准选好化除药剂,提高用药质量,确保除草效果。具体化除意见如下: In 2016, Nantong, Jiangsu and other regions of middle and late japonica rice cultivation patterns are still diversified, direct seeding rice, machine transplanted rice, hand-planted rice co-exist. Direct-broadcast rice fields ecological environment is very conducive to the growth of weeds, machine transplanting seedling age due to the smaller, the higher the safety of herbicides. Chemical weeding is an important measure to control grass damage and seize high yields of rice. All localities should make classified guidance according to the local rice cultivation methods and pastures and grasslands, select the appropriate drugs to remove them, and improve the quality of medicines to ensure the weeding effect.
