  1. It meaned that simulated acid rain made the toxic effects of zn or cd on growth of the plants more serious. the fresh weights and chlorophyll contents of phaseolus vulgaris l were the highest when ph value of acid rain was 4. 5, zn concentration was 60 mg / kg, and or cd concentration was 0. 5 mg / kg. this showed that lower acidity of simulated acid rain and lower concentrations of zn or cd could promote growth of the plants

    本試驗中，酸雨加zn或者酸雨加cd使小白菜鮮重小於單一污染處理，說明酸雨增加了zn 、 cd對小白菜的毒害作用；而當酸雨ph值為4 . 5 、 zn濃度為20mg / kg或cd濃度為0 . 5mg / kg時，四季豆鮮重達到最大值，這表明低強度的酸雨和低濃度的zn 、 cd促進四季豆的生長。
  2. Toxic effects of high acidity of acid rain and high concentrations of zn or cd on growth of brassica chinensis l and phaseolus vulgaris l were obvious, which was showed in the fact that the leaves were smaller and narrower than the contrast, and the growth of the plants were inhibited

    強酸性降雨和土壤高濃度的zn 、 cd污染對小白菜和四季豆生長產生毒害作用，主要表現在葉片變窄變薄，失綠現象明顯，植株矮化，生長發育受阻。小白菜、四季豆根、葉中mda含量與zn 、 cd濃度呈正相關。
