摘　　要：试验研究了稻作超稀植栽培下 ,丛插基数和插秧密度对产量诸构成因素的影响。结果表明 :超稀植时 ,插秧密度对分蘖率、结实率的影响不显著 ,而插秧基数成为增产的限制性因子 ;丛插基数和插秧密度具有密切的互补性 ,插秧密度 2 9 7cm× 19 8cm ,丛插基数为 1株 /穴的处理更有利于产量的增加 ;插秧密度相同而行株距有差异的两组处理相比 ,宽行距的处理更能协调群体的光能利用和改善通风能力 ,从而提高产量。The results showed that the density of transplants hasn′t effected the factors of yield such as the tillering capacity and seed setting percentage markedly While the number per hole has become restrictive factor of the yield And the density of transplants was interplay with the number per hole At the same time that the yield in wide row spacing was higher than in narrow row spacing under the same density of transplants in supper wide spacing planting.
