| 摘 要： | 油稻稻制是洞庭湖地区的典型稻作制度。由于季节茬口矛盾大，生产上已形成了“重晚稻轻早稻”的习惯。品种搭配主要是以早配迟、中配迟为主，约占90％。早稻产量一般每667m’仅300kg左右。晚稻虽近500kg，但双季总产一般也只有800kg。为了实现国家水稻工程双季稻eevm‘单产跨“三纲”（1200kg）的目标，生产潜力的挖掘必须着眼于早稻，因而“国家水稻工程”临法基点确立了以品种（组合）“满负荷”搭配为核心的高产技术策略，在核心区24．6hm’的大面积上开展了示范研究，以缩短小区试验与大面积推广的时间与技术差距，为三熟制双季稻区实现…

| Abstract: | The different collocation patterns of double-cropping rice cultivars in the rape-rice-rice system areahave demonstrated the following results: it is easy for reaching high yield to collocate the late-maturing early rice(LME), Xiangzaoxian 19 and 810 S/D100 with the late-maturing late rice (LML),Pei'ai 64S/Teqing;while the midmaturing early rice (MME) with the LML or the LME with the mid-maturing late rice (MML) gives the loweryields, and the early-maturing early rice (EME) with LML gives the lowest output. In order to produce high yield indouble-cropping rices and develop the yield potential for the early rice, it is necessary to make the collocation be"full capacity", and adopting the matching skills of the seedling raising is the key technique to let "full capacity" butnot "over capacity" of the collocations. |
