| 摘 要： | 以冬闲-双季稻种植模式为对照(CK),研究了在紫云英-双季稻(T1)和油菜-双季稻(T2)种植模式下秸秆还田对水稻生长发育和产量的影响。研究结果表明:在3种不同种植模式条件下,以T1处理下秸秆还田的效果最好;与CK相比,T1处理可以显著地促进水稻分蘖,提高水稻植株的叶面积指数、干物质积累量和茎鞘转运率,增加有效穗数、每穗粒数、早稻的结实率以及晚稻的产量。

| Abstract: | Taking the cultivation mode of winter fallow-double cropping rice(CK) as the check,this paper studied the effects of straw-returning on the growth and grain yield of rice cultivated by Astragalus sinicus-double cropping rice mode(T1) and rape-double cropping rice mode(T2).The results showed that: among the three cultivation modes,T1 had the best straw-returning effect.Comparing with CK,treatment T1 could observably promote tillering,increase the leaf area index,dry matter accumulation and stem-sheath transfer ratio of rice plants,and enhance the effective spikes,grains per spike,early-rice’s seed setting rate and late-rice’s yield. |
