| 摘 要： | 本试验通过模拟酸雨对北方偏碱性土壤种植蔬菜中叶绿素、可溶性糖,IAA等的影响,说明北方也存在酸雨的危害。因北方冬季取暖期长,雪水的pH值偏低,长期的作用,土壤的酸化将使农作物的营养成分发生变化和产量降低。

| Abstract: | In this paper it is shown by the influence of imitative acidic rain on the chlorophyll, soluble saccharide, IAA and so on in the vegetables planted in the north basic soil that there is the harm of acidic rain also in the north. In the long period of winter in the north the PH of snow water is low, these fore, the cidificaiotn of soil will make the nutrition composition changed and make the output reduced. |
