研究了柞树林下菌根真菌对Ｃ、Ｎ营养的利用状况．结果表明，供试菌种对Ｃ源的利用较为广泛，葡萄糖、果糖为其最适碳源，平均生长量比对照高出４．４倍；供试菌种对有机氮的利用优于无机氮，平均生长量比无机氮源高出１．６倍，硝态无机氮源中平均生长量为对照的２．５倍，对铵态氮的利用较差，平均生长量仅为对照的２．２倍
The utilization of C, N nutrition in mycorrhizal fungi was studied. The results showed that the tested strains were widely used C source, glucose, fructose as its optimum carbon source, the average growth of 4.4 times higher than the control; test strains of organic nitrogen utilization is superior to inorganic nitrogen , The average growth rate was 1.6 times higher than that of inorganic nitrogen source, the average growth rate of nitrate inorganic nitrogen source was 2.5 times that of the control, the utilization of ammonium nitrogen was poor, and the average growth was only 2% of the control. 2 times
