| 摘 要： | 本实验是利用以牡蛎壳为主要材料的 3种不同用量的盐碱土壤修复材料 ,处理含盐量为 2的低度盐碱土壤 ,对作物油菜的形态及其生理生化指标进行对比测量 ,用以观察此修复材料对盐碱土壤的修复作用。实验表明 ,此修复材料对种植 4 0 d后的油菜的出苗率无显著影响 ,而对叶长、叶宽等形态有明显影响。改良后的盐碱土上生长的油菜的叶绿素含量及叶绿素 a与叶绿素 b的比值均上升 ;叶片类囊体膜 H+ - ATPase活性上升 ,证明此盐碱土壤修复材料对盐碱土壤具一定的修复作用 ,且其修复作用与修复材料的添加用量有关。

| Abstract: | In order to find the effect of the saline lands restoration material, which was mainly composed of oyster shell, the indexes of morphology, physiology and biochemistry of the rape growing on the saline soil (s=2) were measured after treatment with three concentrations of this material. The experiment indicated that this material did not produce much influence on the germinating rate of rape 40 days after planting. However, the length and width of the third leaves, the chlorophyll content , the value of chla/chlb and the activity of H+-ATPase in the thylakoid membrane of rape increased significantly afrer treatment. These results show that the saline lands restoration material has the capability of restoration and its function is in proportion to the dose. |
