| 摘 要： | 在毛白杨外生菌根菌生态学特性和共生关系研究的基础上，对与毛白杨有良好共生关系的外个菌根菌的研究表明，硬皮马勃能耐温，在碱笥条件下仍能生长，在中性基质中，均能与毛白杨形成菌根，并大幅度地提高毛白杨的生长量。但在碱性土壤中，仅有硬皮马勃能与毛白杨形成一定数量的菌根，并能明显地提高毛白杨的生长量、地上部分生物量，改善菌木Ｎ、Ｐ的营养状况，接种效果随接种量的变化而差异明显。

| Abstract: | Based on the ecological characteristics and symbiotical relationship of ectomycorrhizae of Populus tomentosa,the research on the beneficial ectomycorrhizal fungi has been conducted.The results show that Scleroderma sp.is not only able to endure the high temperature as compared with the other fungi,but also to grow in the alkaline substratum.In neutral substratum all of the Tricholoma columbetta,Laccaria laccata and Scleroderma sp.could form ectomycorrhizae with the host plant and improve the host's growth,but in alkaline soil only Scleroderma sp.formed ectomycorrhizae,which bettered the host growth and its nutrient situations of nitrogen and phosphate.Its effect of inoculation rose obviously with the increase of the inoculum amount.A worse effect resulted from the inoculation experiment of Cenococcum geophilum. |
