摘　　要：试验研究不同栽培模式（超高产栽培模式和常规栽培模式）对再生稻头季稻株叶绿素含量、叶面积指数、干物质积累运转及产量构成的影响结果表明，秧苗移栽大田后，超高产栽培模式头季稻株的叶绿素含量和叶面积指数从分蘖期到成熟期均比常规栽培模式的高，在生长中、后期尤其显著，分别高10．77％和63．29％；超高产栽培模式的群体干物质累积总量在头季稻整个生育期比常规栽培模式高24．83％-38．17％，茎鞘物质运转率、茎鞘物质转换率分别比常规栽培模式高10．60％和13．88％，单位面积有效穗数比常规栽培模式多21．43％，穗粒数多1．88％，产量比常规栽培模式高24．22％。The effect of different cultivation patterns（Super High-yield Cultivation Pattern, SHCP; and Tradition Cultivation Pattern,TCP） on chlorophyll content, Leaf Area Index（LAI） , dry matter accumulation and transportation and yield component of the first-flee crop of ratoon flee were studied. Results indicate that chlorophyll content and LAI of the first-flee crop under super highyield cultivation pattern are higher than those under the tradition pattern from tillering to ripening stage,especially during the middle and latter periods,by 10.77% and 63.29% , respectively. Compared with the tradition cultivation pattern,accumulation of population dry-matter under super high-yield cultivation is 24.83% - 38.17% higher;transportation of stem-sheet matter is 10.60% and transformation of stem-sheet matter is 13.88% higher;productive tillers per hectare increase by 21.43% ;and yields increase by 24.22%.
