在不同栽培密度条件下，对水稻新品种“吉农大7号”生育指标及产量构成性状因子进行研究分析表明：随着栽培密度的降低，“吉农大7号”的分蘖力提高，叶片数增加，生育期延长。不同栽培密度条件下“吉农大7号”的穗数、粒数、叶面积指数差异明显，而株高只有在30 cm×13．2 cm密度下较其他密度明显变矮，千粒重基本趋于稳定。“吉农大7号”的最适栽培密度为30 cm×19．8 cm即(17穴／m2)，产量可达9 500kg／hm2以上。

Growth, development and yield determing components of rice, cv. “Jinongda 7” under different plant densities were studied. With the decrease of plant density, the number of tillers and leaves increased and growth period extended. Significant differences were found in the number of panicles and grains and leaf area index (LAI) under different plant density. However, plant height significantly decreased only at 30 cm×13.2 cm plant density compared with that at other plant densities. Plant density had no effect on grain weight. The highest yield, 9 500 kg/bm2, was obtained at plant density 30 cm×19.8 cm.
