早在1956年,我们已对松树和柞树的外生菌根真菌进行了分离。当时获得三株菌根真菌的纯培养,经初步鉴定分属于牛肝菌属(Boletus)、乳菇属(Lactarius)和滑菇属(Hebeloma)。回接试验取得了成功。在樟子松(Pinus sylvestris)幼苗的接种试验中,也获得了较好的结果;菌根化促进了樟子松幼苗的成活。但由于我们采用的分离方法是表面灭菌法,直接从松树的小根上来分离菌根真菌 As early as 1956, we have isolated the ectomycorrhizal fungi of pine and oak trees. At that time, three strains of mycorrhizal fungi were purely cultured. After preliminary identification, they belong to Boletus, Lactarius and Hebeloma. Back to the test has been successful. Good results were also obtained in inoculation experiments of Pinus sylvestris seedlings. Mycorrhiza promoted seedling growth of Pinus sylvestris. However, since the separation method we used is the surface sterilization method, mycorrhizal fungi are directly isolated from the small roots of the pine
