Abstract: The different collocation patterns of double-cropping rice cultivars in the rape-rice-rice system area have demonstrated the following results: it is easy for reaching high yield to collocate the late-maturing early rice(LME), Xiangzaoxian 19 and 810S/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 lower yields, 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" but not "over capacity" of the collocations.

Key words: rape-rice-rice cropping system, collocation pattern of rice cultivars, seedling raising technique
