| 摘 要： | 与湿润育秧秧苗比较，早稻旱育秧苗大田植株在根系生长、根系活力、根系呼吸作用和发根能力等方面具有明显的优势，这些优势随生育期延长而逐渐减小；两种秧苗本田植株生育后期功能叶片衰老速度无明显差异，但旱育秧苗植株茎秆比湿润育秧秧苗植株更坚韧．

| Abstract: | The results of the studies as titled showed that the plants developed from the early rice seedlings raised in dry nursery (PDERSRDN) obviously had more advantages in root growth,root vigor,root respiration and root reproducing ability compared with the plants developed from the early rice seedlings raised in wet nursery (PDERSRWN),but all these advantages gradually weakened with the development of the plants,and that the senescence speed of functional leaves of the two kinds of plants showed no significant differences during the late life stages,but the stem of PDERSRDN developed much sturdier than that of PDERSRWN. |
