| 摘 要： | 以4种不同基因型水稻为材料,研究磷素水平对水稻幼苗的生物学和营养学性状的影响.结果表明:低磷处理对水稻幼苗各生物学性状影响很大,低磷条件下水稻幼苗株高、鲜重、干重均低于对照处理,根长伸长,根冠比增大;供磷过量处理水稻幼苗株高和干重低于对照.四种水稻幼苗相比,高优35的磷素利用效率明显低于其它三个品种.

| Abstract: | Biologic and plant nutrient characteristics of rice were investigated with 4 lines at seeding stage.The results showed that P deficiency has a great influence on biological traits.With the lowering of P in medium,plant height,dry weight,fresh weight of rice seeding were lower than control's,but the roots length and root/shoot increased at the early stage.Plant height,dry weight of rice seeding was lower than control's under high phosphorus levels.In the four lines,P utilization efficiency in 35 was lower than others. |
