摘 要 ：以小麦为试材，采用盆栽的方法研究了模拟酸雨及其酸化土壤对小麦幼苗生物量和某些生理活动的影响。结果表明，pH值为5.6、4.5、3.5、3.0和2.5的系列模拟酸雨对黄棕壤的淋溶，引起了土壤酸化和盐基流失。当模拟酸雨的pH值由5.6下降到2.5时，被淋溶土壤的pH值也由6.06下降到3.41，且交换性盐基总量从56.5 mmol·kg-1下降到41.1

Abstract:Acid rain can damage either plant leaves directly or plant roots indirectly resulting from soil acidification and release of base ions. The stress effect of acid rain and its acidified soil does a lot of harm to the plants. A pot experiment of wheat seedlings was conducted to study the effects of si
