Abstract：
In this study, the effect of soil ameliorators on ectomycorrhizal (ECM) fungal communities in coal mine spoils was investigated. Organic fertilizers and slaked lime were applied as soil ameliorators in 3 abandoned coal mine spoils. One year after the initial treatment, roots of Pinus densiflora seedlings were collected and the number of ECM species, colonization rate, and species diversity were assessed. The results showed that the soil ameliorators significantly increased ECM colonization on the roots of P. densiflora. The results suggest that soil ameliorators can have a positive effect on ECM fungi in terms of growth of host plants and show the potential use of soil ameliorator treatment for revegetation with ECM-colonized pine seedlings in the coal mine spoils.
摘要：
在这项研究中,研究了土壤改良剂对煤矿弃渣中外生菌根（ECM）真菌群落的影响。在3个废弃的煤矿弃土中施用了有机肥料和熟石灰作为土壤改良剂。最初治疗一年后，收集了黑松幼苗的根系和ECM种类的数量，定殖率,并对物种多样性进行了评估。结果表明，土壤改良剂显著增加了根茎上的ECM定植。结果表明，土壤改良剂可以在寄主植物的生长方面对ECM真菌产生积极影响，并显示了土壤改良剂处理在煤矿弃土中使用ECM定植的松树幼苗进行植被恢复的潜在用途。
