摘　　要：概述了国内外再生稻研究与生产现状 ,分析了其在生产上的利用优势与当前存在的主要问题 ,并用培两优5 0 0作中稻进行了蓄留再生试验 .结果表明 ,培两优 5 0 0中稻加再生稻产量达 1 2 0 82 .5 kg/hm2 ,实际产量已达双季稻的全年产量水平 ,比汕优 6 3(对照 )增产 37.5 % ,米质明显优于对照 。Progress on research and utilization of ratoon rice was reviewed, including the advantages and the principal problems in the utilization of ratoon rice at present. Two line hybrid rice Peiliangyou 500 was used as the experimental material for ratooning after middle season rice. The results showed that the total yield of middle season and ratooning rice of Peiliangyou 500 is 12 082.5 kg/hm 2,which is 37.5% more than that of Shanyou 63(CK).The former's rice quality is significantly better than the latter's.
