摘要
在霍林河露天煤矿脆弱生态地带的生态修复中 ,应用菌根生物技术 ,选用露天开采的剥离物绿色泥岩 ,以施肥和不施肥、泥岩氨化等处理进行不同条件的盆栽模拟试验 .结果表明 ,绿色泥岩接种菌根菌剂 ,不施肥的感染率和成活率均高出施肥的 1.2 1～ 2 .78倍和 1.0～ 2 .7倍 .供试的菌根菌剂中 ,0 10、A和B菌剂对贫瘠和渗透率低的土壤条件表现出较强的调控能力 .泥岩氨化对其理化条件虽能有所改善 ,但氨和磷聚集使幼苗成活时间甚短 .
Pot experiment with discarded greenish mudstone from large opencut coal mine as test soil was conducted to study the application of ectomycorrhizal fungi in the ecological reconstruction of fragile ecological belt of large opencut coal mine of Huolinhe region, Inner Mongolia. The result showed that after the greenish mudstone was inoculated with ectomycorrhizal fungi, the rates of seedling infection and survival were 1.21～2.78 higher in treatment with no fertilizer application than in that with fertilizer application. The test ectomycorrhizal inoculum 010, A and B had a stronger regulation ability in infertile and low penetration coefficient soil. The ammonification of the mudstone could improve its physical and chemical properties, but shorten the survival duration of seedling on account of the accumulation of ammonia and phosphorus in it.
