将菌根真菌接种于复垦土壤中 ,进行了盆栽试验研究 .结果表明 ,植株的生物量随覆土厚度增大而增大 ;与非菌根植物相比 ,接种菌根真菌的植物可以吸收更多的营养 ,而向地上部运移的 Na较少 ,抑制了植株积累过量的 Na盐 ;植株生物量及其植株体内的营养元素含量 ,接种菌根真菌后 ,覆土少的 (覆 5 cm厚的土壤于 1 0 cm厚的粉煤灰上 )相应高于不接种且覆土厚 (覆1 0 cm厚的土壤于 5 cm厚的粉煤灰上 )的 ,说明接种菌根具有抵消由于覆土少而导致的植株产量降低的潜力 ,其对粉煤灰充填复垦的植被重建具有重要作用 ,而且可以节约复垦费
Inoculation of mycorrhizal fungi in reclaimed soil and pot experiments were carried out.The results showed that the biomass of plant increased with the increase of soil cover thickness.Compared with non-mycorrhizal plants, plants inoculated with mycorrhizal fungi could absorb more More nutrients, while the Na transported to the shoots is less, inhibiting the accumulation of excess Na salt plant; plant biomass and nutrient content in plants, inoculated with mycorrhizal fungi, less soil cover (covered 5 cm thick Of the soil on 10 cm thick fly ash) was correspondingly higher than that of the uninoculated and cover soil (covered with 10 cm thick soil on 5 cm thick fly ash), indicating that the inoculation of mycorrhizae had the effect of counteracting the lack of casing The potential for reduced plant yield has an important role in the reconstruction of fly ash-filled reclaimed vegetation and can save reclamation costs
