经1997 、1998 两年的试验示范与技术研究表明, 通过两季茬口合理衔接、适宜组合搭配、化调控苗、适龄抛栽、科学管理等手段, 获得连作早晚稻双杂双抛高产稳产, 形成一套适合浙南沿海地区光、温条件和生产实际的双杂双抛技术体系。 After 1997, 1998 two years of pilot demonstration and technical research shows that through the two crop stubble reasonable convergence, the appropriate combination of collocation, regulation and control of seedlings, age throwing planted, scientific management and other means to obtain continuous cropping early and late rice double hybrid double throw high and stable yield, formation A set of suitable light and temperature conditions in southern Zhejiang coastal areas and the actual production of double hybrid technology system.
