摘要
针对西部干旱半干旱煤矿区沉陷地复垦存在的主要障碍因子,如根系功能降低、土壤结构破坏、土壤肥力低下、水肥不协调供应等,利用丛枝菌根真菌本身在修复根系功能、促进养分吸收运输及改良土壤方面具有的强大的生命力与适应性特点,将优势丛枝菌根真菌作为采煤塌陷地复垦新突破口。本文对丛枝菌根真菌对难溶性磷的溶解、吸收与运输机制,对复垦土壤的水肥供应,拉伤根系修复,土壤结构改良及生态修复效应等方面的研究进展进行综述,为西部干旱半干旱煤矿区生态修复奠定技术基础。
For the sake of overcoming the main obstacle factors of coal mining subsidence land reclamation in arid and semi-arid land, such as low soil fertility, inconsistency of water and fertilizer, reduction of root system function, damage of soil structure, decline in land productivity and the difficulty in ecological restoration, the application of arbuscular mycorrhizal fungi（AMF） have been taken as one of the new breakthrough points for reclaiming coal mining subsidence land. The research advances on the mechanism of the AMF on hard dissolved phosphorus absorption and transportation, the coordinating supply of water and fertilizer in reclaimed soil, root function restoration, and soil structure improvement are reviewed in this paper.
