模拟酸雨处理土壤对绿豆植株某些生理性状的影响

Influence of Soil Treated by the Simulated Acid Rain on the Physiological Characteristics of the Mungbean Plants

通过盆栽绿豆试验,研究了不同pH值的模拟酸雨处理土壤对绿豆植株某些生理性状的影响。结果表明：随着模拟酸雨pH值的降低,叶片出现了皱缩、白色斑点、萎蔫等伤害症状；绿豆叶片的大小、株高、植株鲜重均明显受到了抑制；叶片叶绿素的含量略有增加；当酸雨的pH值为2．0时,植株表现出全部萎蔫的现象。

The effects of soil treated by the simulated acid rain with different pH values on some physiological characteristics of mung bean plants are investigated out by means of the bean planting experiments in the pots. The results show that, with the lowering of the pH value of simulated acid rain, the leaves show some hurt symptoms of crinkles, white dots, wilting, etc. ; and the size, height, plant fresh weight of the mung bean leaves are significantly inhibited; while the chlorophyll content of the leaves is increased slightly. When the pH value of the simulated acid rain decreases to 2.0, the bean plants are wilting heavily.
