| 摘 要： | 以粳稻品种秋光和籼稻品种密阳23为试验材料,研究了不同施氮水平对不同类型水稻根系生理特性的影响。结果表明,较高的氮素水平促进根系生长,迅速提高水稻根干重,但同时降低根冠比。除生育前期外,籼稻根系吸收面积均大于粳稻根系吸收面积,籼粳稻比表面积比较接近。 |

| Abstract: | Making experiment with japonica rice Qiuguang and indica rice Miyang-23,studies the influence of nitrogen applying in different levels on physiological characteristics of different root systems of rice.The result is,high N-level can promote the root to grow,but the root cap ratio will comes down.Except the early growing period,absorbing area of root of indica rice is always bigger than that of japonica rice. |
| Keywords: | nitrogen rice root system physiologic characteristic |
