摘　　要：从杉木林土壤中筛选到 5株高效解酚菌 (F2 、F3、F4 、F7、F15)通过盆栽试验 ,发现F4 能抑制杉苗生长 ,而其余四株则能在不同条件下促进杉苗生长 ,但不能完全抵抗所加酚酸的抑制作用 ,而将五种菌按等比例混合后使用 ,则不仅能促进菌根苗Z和非菌根苗生长 ,还能抵抗酚酸的抑制作用。The successive plantation of China fir(Cunning hamia Lanceolata)leads an obvious decline of soil fertility and production of wood,which hinders the sustainable development of forestry.To solve these urgent problems,five fungal species (F 2、F 3、F 4、F 7、F 15 )which can degrade phenolic acid effectively were screened to degrade the toxical material in successive plantation site and improve the bioactive of soil.All the screened fungal species,except F 4,can promote the fir'-s growth under different condition can't counteract the phenolic acid's bad effect,while the mixed fungi(mixed with equal proportion )can cornteract the inhibitory effect and promote the uninoculated fir and the fir inoculated with G.mosseae Z,yet the fir inoculated with G mosseae W is inhibited by the mixed fungi.
