摘要: 排土场的建设彻底破坏了矿区的生态环境，阻碍了植被恢复进程。本研究通过向排土场土壤中生长的油松幼苗接种外生菌根真菌牛肝菌-99和褐环乳牛肝菌，测定油松幼苗的生物量、叶绿素含量、光合指标和根际土壤酶活性的变化，探究将外生菌根真菌应用到排土场植被复垦中的可行性。结果表明，接种褐环乳牛肝菌后，油松幼苗的存活率、生物量明显提高；幼苗的叶绿素含量和光合指标明显升高；根际土壤酶活性显著提高(P < 0.05)，说明接种外生菌根真菌有助于排土场土壤中油松幼苗的生长，可以促进排土场植被恢复的进程。
Abstract: The construction of dump completely destroyed the ecological environment of mining area, obstructing the process of revegetation. In the study, Pinus tabulaeformis seedlings on dump soil were inoculated with Suillus collinitus-99 and S. luteus. Biomass, chlorophyll content, photosynthetic indexes and the activities of rhizospheric soil enzymes of seedlings were determined for exploring the feasibility of applying ectomycorrhizal biotechnology to revegetation. The survival rate and biomass of seedlings was significantly increased when seedlings are inoculated with S. luteus. Moreover, seedlings have more obvious growth chlorophyll content, photosynthetic indexes and the activities of rhizospheric soil enzymes of seedlings (P < 0.05). The results show that the growth of seedlings was significantly improved when inoculated with ectomycorrhizal fungi; ectomycorrhizal fungi can accelerate the process of revegetation.
