| 中文摘要: |
| 为了筛选拮抗油松猝倒病菌及对油松苗木具有促生作用的外生菌根（ectomycorrhizal，ECM）真菌，通过对盆栽油松幼苗进行人工接种，测定了ECM真菌对油松根的侵染率、对猝倒病的防治效果以及对油松株高和地径的影响。结果表明，供试ECM真菌中，绒粘盖牛肝菌Suillus tomentosus、灰环粘盖牛肝菌Suillus laricinus、灰鹅膏菌Amaniata vaginata和血红铆钉菇Gomphidius viscidus可在盆栽条件下与油松合成菌根。灰鹅膏菌对油松猝倒病防治效果最好，为43% |
| 英文摘要: |
| In order to screen ectomycorrhizal (ECM) fungi for antagonizing Rhizoctonia solani and improving the growth of Pinus tabulaeformis seedlings, 9 species of ECM fungi were inoculated to the roots of P. tabulaeformis seedlings under controlled conditions, and then colonization rates, control effects of inoculation on damping off of P. tabulaeformis, effects of inoculation on plant height and basal diameter of P. tabulaeformis were measured. The results indicated that, 4 species including Suillus tomentosus, Suillus laricinus, Amanita vaginata and Gomphidius viscidus could form mycorrhiza with P. tabulaeformis seedlings in greenhouse. A. vaginata was the best strain for controlling P. tabulaeformis damping off, and the control effect was 43%. A. vaginata and G. viscidus could significantly improve plant height of P. tabulaeformis seedlings. |
