水稻不同品种之间生长量差异较大，但不同密度间差异小．不同品种在稀植（３０×２６ｃｍ）处理下有效分蘖终止期同密植（３０×１３ｃｍ）相比，普遍向后延迟，且其叶龄指数分别为２０和６４，但最高分蘖期无明显差异，其叶龄指数分别为８０和７９；二次分蘖穗明显增多，提高了有效分蘖率；茎基部伸长节间短而粗，上部节间拉长，折损重大，抗倒能力增强，不同品种间都有同样的趋势．产量与结实率（ｘ１）、千粒重（ｘ２）、ｍ２穗数（ｘ３）、穗粒数（ｘ４）间回归方程为经产量方差分析结果表明不同品种、不同密度间和互作差异不显著．据各种农艺性状的终合分析，秋田３２是较适合烯植栽培的优良品种．
The differences in growth between different rice varieties are quite different, but the differences among different densities are small. Compared with the close planting (30 × 13cm), the effective delay of tillering of different cultivars under thinning (30 × 26cm) treatment was generally delayed, with leaf index of 20 and 64, respectively, but the highest tillering stage had no significant difference , The leaf age index was 80 and 79 respectively; the secondary tillering spike increased obviously, and the effective tillering rate was increased. The short and thick stem internode elongation, the upper internode elongation, The same trend among varieties. The regression equation between yield and seed setting rate (x1), 1000-grain weight (x2), m2 panicle number (x3) and grain number per spike (x4) showed that there was no significant difference among different varieties under different density with yield variance analysis. According to the final analysis of various agronomic traits, Akita 32 is more suitable for the cultivation of fine varieties of alder.
