丛枝菌根对矿区环境修复的生态效应

Ecological effects of arbuscular mycorrhizal fungi on environmental phytoremediation in coal mine areas

针对煤矿区生态环境修复过程中存在的主要问题,通过定位监测菌根的生态来探索菌根生物技术在矿区环境治理的效应与推广模式。菌根对植物生长具有明显的促进作用,接种菌根6个月后杨树和白蜡的胸周和株高分别较对照明显增加,菌根侵染率达到80%以上,菌根与植物共生作用好。接种菌根菌6个月后,菌根际菌丝长度远远高于对照,产生的孢子数量也明显增加,接种菌根菌对于降低煤矿区环境修复成本以及增加未来生态收益具有很大的潜力,维持了矿区生态系统的稳定。

Arbuscular mycorrhiza （AM） has been used to resolve the key environmental problems in coal mine areas. Arbuscular mycorrhizal fungi can improve plant growth and establish good symbiosis with plants. After inoculation with AM 6 months, the plant chest perimeter and its height are greater than those of non-inoculation treatment. Infection rate of plant is over 80% and hyphal length is much greater than control, so is the spore density. Mycorrhizal applying in the field can decrease the cost of environmental phytoremediation, which also keep the ecosystem stability.
