Abstract: In Kubuqi sandland adjusting measures to local conditions and spots were emphasized particularly to restore vegetation with mycorrhizal technology.According to the local sand soil condition,A and B,which were treated with meadow peat or without,respectively,were used,and the local planting species,Pinus tablaeformis and P.sylvestris were selected,while the single innoculum and double innoculums were brought into effect.The results in indoor simulated experiments showed that:the single innoculum effects on P.tablaeformis was in order of Cr> Ra >Li >Hm.It was not strongly dependent on meadow peat for seedlings inoculated in double combination innoculum Ra+Li,Hm+Lih and Ra+Cr.But all of the seedlings in CK soil without meadow peat were not growing.Cr and Ra were recognized as the better innoculums for the restoration of sand vegetation.P.tablaeformis growth potential was higher than P.sylvestris whether using single innoculum or double combination.The results in outdoor minitype planting trials showed that:at the same plot three combination innoculum was better than double combination.The seedling biomass inoculated mycorrhizal innoculum was higher than that used compound fertilizers.Survival rate of seedlings treated with inoculums at different plots was lower than that applying compound fertilizers.It was conferred that due to time short mycelium and medium were not completely fermented in some of the cultured individuals.In combination with drought and soil temperature rising,the medium continue fermenting and decaying,which injured the relatively weak seedlings.Therefore the survival rate of seedlings was low.
