在盆栽试验条件下,应用灭菌的露天煤矿区回填土壤为培养基质,研究8个丛枝菌根真菌菌种(株)对沙打旺生长及根系侵染的影响.结果表明,分离自江西和新疆的Glomus mosseae的2个菌株在露天煤矿区回填土壤上能够显著提高沙打旺的生物量,并能有效改善植株的磷、氮营养;其侵染率均在50%以上,且根外繁殖体数显著高于其他接种处理.说明此两个菌株在该土壤上具有良好的生态适应能力,有助于露天煤矿区植被重建和生态恢复等研究工作的进一步开展.
在盆栽試驗條件下,應用滅菌的露天煤礦區迴填土壤為培養基質,研究8箇叢枝菌根真菌菌種(株)對沙打旺生長及根繫侵染的影響.結果錶明,分離自江西和新疆的Glomus mosseae的2箇菌株在露天煤礦區迴填土壤上能夠顯著提高沙打旺的生物量,併能有效改善植株的燐、氮營養;其侵染率均在50%以上,且根外繁殖體數顯著高于其他接種處理.說明此兩箇菌株在該土壤上具有良好的生態適應能力,有助于露天煤礦區植被重建和生態恢複等研究工作的進一步開展.

The effects of eight isolates of arbuscular mycorrhizal (AM) fungi on the plant growth and root colonization of Astragalus adsurgens were investigated in greenhouse pot experiment with backfill soil of open pit mining area. The results showed that two isolates of G.mosseae from Jiangxi and Xinjiang increased the biomass of plant and effectively enhanced P and N nutrition of host plant. The infection rates of these two isolates were above 50%, and the number of extraradical propagule was more than that of the other isolates. It was proved that the ecological adaptability of two isolates, G.mosseae-2 and G.mosseae-3 in the backfill soil were significantly higher than that of the other isolates;they are expected to benefit the plant cover reconstruction and ecological restoration in open pit mining area.
