摘　　要：采用不同pH值的模拟酸雨对杂交苏丹草皖草2号进行处理,测定对其种子萌发和幼苗生长的影响。试验结果表明,酸雨会导致土壤酸化,pH值大于4.0的酸雨对杂交苏丹草种子的发芽和幼苗生长无不良影响,pH值低于4.0的酸雨对杂交苏丹草种子的发芽和幼苗生长具有抑制作用,且pH值越低,所产生的不利影响越大。Effects of simulated acid rain with different pH values on the germination and seedling growth of Sorghum sudanence Wancao No.2 were studied.The results indicated that acid rain could lead to soil acidification.The pH values over 4.0 had no adverse effects on seed germination and seedling growth of Sorghum sudanence,however,the pH values below 4.0 inhibited the seed germination and seedling growth,and the lower the pH value,the greater the negative effects.
