| 摘 要： | 采用盆栽方法,研究了不同pH值的模拟酸雨对空心菜发育生长及钙、铁、铜、镁含量的影响。结果表明:模拟酸雨对空心菜发育率影响不大,模拟酸雨使空心菜中钙、铜的含量随酸雨pH值减小而下降。空心菜中铁含量随酸雨pH值减小而升高,而各处理组空心菜中镁的含量差别不大,表明空心菜对镁的吸收不受酸雨的影响。

| Abstract: | By using the method of potted plant,this article researched how the simulation acid rains of different pH value influence the development and growth of the swamp cabbage and the calcium,iron,copper,magnesium content in the swamp cabbage.The result indicated that simulation acid rain had no influence on the germination rate of the swamp cabbage.The calcium and copper content in the swamp cabbage reduced as the pH value of acid rain decline;The iron content in the swamp cabbage elevated along with the pH value of acid rain reduction.However,the magnesium content had no difference in the swamp cabbage in each processing group;it indicated that the swamp cabbage to the magnesium absorption was not influenced by the acid rain. |
