摘要 在高产栽培条件下,对超级杂交稻两优培九和杂交稻汕优63的株型特征、农艺性状和光合产物的积累动态进行了比较分析,结果表明:两优培九的单产显著高于汕优63,主要原因是前者单位面积有效穗数和每穗总粒数多、结实率高、功能叶的叶面积和比叶重大、光合产物的积累能力强。 Under the conditions of high-yielding cultivation,the comparative analyses of plant type,agronomic characters and accumulation of photosynthetic products between super hybrid rice Liangyoupeijiu and hybrid rice Shanyou 63 were conducted.The results showed that the yield per unit area of Liangyoupeijiu was obviously higher than that of Shanyou 63,the main reasons are that the former has more effective panicles per unit area,more grains per panicle,higher seed setting rate,bigger leaf area and specific leaf weight of functional leaves,stronger ability of photosynthetic products accumulation.
