摘　　要：Z You 272 not only had the advantages of early sowing, early transplanting, early maturity and high yield which middle-season rice owned, but also had the features of low-node tillering, early seedling, multiple shoots and multiple panicles which also middle-season rice owned. Since 2008, middle-season rice＋ratooning rice has been cultured in Luxian and its integrated high-yield cultivation techniques have been popularized, its total extension area has been 4.47×10^4hm^2, the area of middle-season rice＋ratooning rice has been 3.06×10^4hm^2, and the yield of middle-season rice＋ratooning rice has been 14.656-16.308 t/hm^2.Z优272既有中稻早播、早栽、早熟、高产的特点,又有中稻低位分蘖、早发多发苗成穗的特性,2008年以来在泸县作中稻＋再生稻栽培并推广配套高产栽培技术,累计推广种植面积4.47万hm^2,蓄留再生稻3.06万hm^2;中稻＋再生稻产量达14.656～16.308 t/hm^2。
