摘要：20世纪80年代中期以来，工业生产排放的硫化物和氮氧化物越来越多，在大气中形成酸雨（Tatianaeta1．，2002），对森林、水体和农田等生态系统造成相当大的危害。酸雨使土壤的pH值降低、营养阳离子析出、营养阴离子增加、营养物循环和供给发生变化，
To evaluate the effects of ectomycorrhizal colonization on nutrient elements of Masson pine （Pinus massoniana） seedlings grown in acidified soils, we grew Masson pine seedlings with Pisolithus tinctorius （ECM） for 210 days in acidified forest soil collected from Chongqing, Southwest China. Three acid levels were set, that is, pH3.5, pH4. 5 and pH5.6 （served as the control）, and two ectomycorrhizal treatments （inoculated, non-inoculated） were conducted. The results showed that ： 1 ） Compared with CK treatment, both acidic treatments decreased soil pH. The pH4.5 treatment had no effect on exchangeable Ca and cation exchangeable capacity （CEC） , but increased the content of exchangeable Mg. The pH3.5 treatment significantly reduced exchangeable Ca, Mg and CEC. Inoculation with ECM increased soil pH, exchangeable Ca, Mg and CEC. 2） The acid treatments had no effect on soil organic matter and available K, however they significantly reduced the available P and N content in the soil. Inoculation with ECM under pH3.5 treatment increased soil available P and K content than the non-inocultaion treatment. 3） Acid rain treatments increased N content of needles, and decreased P, K, Ca, and Mg content of needles. Inoculation with ECM reduced N content of needles, and increased P, K, Ca, and Mg content of needles. 4） Acid rain treatments decreased P, K, and Mg content of roots, however inoculation with ECM increased these elements contents, and reduced A1 content of roots. These results indicated that inoculation with ECM could effectively alleviate acid rain stress, increase soil buffer capacity to acid rain, decrease A1 poison, and increase nutrient absorption capacity and nutrient balance of plants.
