| 摘 要： | 在中性及酸性紫色土上,pH2模拟酸雨喷淋蔬菜,使叶片产生褐斑、生物活性下降、生长严重受阻,产量较对照低23—85%,品质变差,叶绿素、氨基酸及维生素 C 含量下降,萝卜的可溶性糖及钙、镁等含量减少。在酸性土上,pH3酸雨对大多数作物的生长有抑制作用,产量稍有下降。根灌酸雨对蔬菜地上部影响较小,对地下部的生长发育有抑制作用,尤其在酸性土上,pH2处理的植株,受害更为严重,根量明显减少。

| Abstract: | The results of pot culture show:when pH 2 model acid rain sprayedthe vegetables in the neutral and acid purple soils,it gives rise to brownspots for vegetable leaves,decreases organic activities and restrains theirgrowth,so that the yield are 23-85% less than those of the check testsand the quality becomes worse.The contents in the chlorophy,Amino-acid and vitamic C of the leaves are diminished,and so are the contentsof sugar,calcium and magnesium of the radish.The pH 3 acid raininhibits the most growing plants in the acid soil,and as a result,theyields decrease slightly.When the acid rain irrigates roots,it has slighteffect on stems and leaves,but inhibits the growth of roots seriously,especially in the acid soils,and consequently,the number of rootsdecreases apparently. |
