2000年安徽省宣城市组织技术人员赴上海考察,认为上海市的机械化水直播技术已经成熟,应引进安徽省宣城市推广,但宣城市水稻生产以种植杂交稻为主,上海以种植粳稻为主,粳稻用种量大(亩用种5kg以上),杂交稻用种量小(亩用种量1kg),杂交稻能否使用机械化直播,是该项技术能否在杂交稻产区大面积推广的关键。因此,2001年安徽宣城市在泾县安排了18亩杂交稻机械化水直播技术试验示范,通过精心管理实施,试验示范获得成功,平均亩产达千斤,与当地
In 2000, Xuancheng City, Anhui Province, organized technical personnel to visit Shanghai and concluded that mechanized water-directing technology in Shanghai is mature and should be promoted in Xuancheng, Anhui Province. However, Xuancheng is dominated by hybrid rice production in rice production and mainly in Japonica rice cultivation in Shanghai , Large seedbed for japonica rice (over 5kg for mu), small amount of hybrid rice (1kg for mu), and whether or not mechanized live hybrid rice can be used. Whether this technology can be widely promoted in hybrid rice producing areas key. Therefore, in 2001, Xuancheng City, Anhui Province, arranged 18 mu of hybrid rice mechanized direct-see-water technology demonstration in Jing County. Through careful management and implementation, the pilot demonstration succeeded with an average yield of one kilogram per mu,
