为探讨规模化稻鸭共育能否改善水稻的株型结构从而影响产量及产量结构的形成,本文通过大田规模化稻鸭共育、常规稻鸭共育和水稻直播的对比试验,研究了水稻分蘖末期和齐穗期的部分株型结构及水稻产量。结果表明:与常规稻鸭共育相比,规模化稻鸭共育减少水稻实际产量和有效穗,水稻部分株型结构各构成因素差异不显著;与水稻直播处理相比,规模化稻鸭共育在分蘖末期和齐穗期降低植株茎基宽,增加冠层幅度,保持植株具有一定松散度;增加剑叶和倒2叶叶开角、披垂度和叶片长度,降低倒3叶和倒4叶叶开角和披垂度,利于植株形成上披下挺的株型结构;增加剑叶、倒2叶和倒3叶叶面积占比,使叶面积较多的分布在上部叶...

An experiment was conducted to assess whether large-scale rice-duck farming could improve the plant architecture of rice, which in turn influences the yield and yield components. Three treatments including large-scale rice-duck farming, normal rice-duck farming and direct sowing were established to investigate plant architecture at late tillering and full-heading stages and grain yield of rice. The result showed that, compared with the traditional rice-duck farming, large-scale rice-duck farming decreased the actual grain yield and the number o...
