以穗型直立的紧凑型水稻品种沈农07425和穗型弯曲松散型水稻品种秋光为材料，在不同氮素水平下研究两种株型品种的根系形态特性。结果表明，施氮条件下单株根长在不同株型品种间存在差异，沈农07425单株根长随施氮量增加而减少，而秋光则在高氮条件下单株根长最长，单株根长主要受品种株型影响。单株根干重、根体积表现一致，主要受施氮水平影响，且随施氮水平的提高而增大。

The compact rice Shennong 07425 with erect panicle and the loose rice Akihikari with curved panicle were used to study morphological characteristics of root under different nitrogen levels. The results showed total length of root in Shen-nong 07425 decreased with the increase of nitrogen level, but the total length of root of Akihikari reached the maximum at high N level. The total length of root was mainly affected by plant type. There was the same trend of dry weight of root, root volume between the two varieties. The indicators were mostly influenced by N level and became stronger with the in-crease of N level.
