摘　　要：The research explored the effects of carbon, nitrogen and inorganic salt nutritional factors on Lactarius deliciosus hyphae as per solid culture. The optimal recipe of culture medium was selected by observing hypha density and computing the growth index, which is the most suitable for hypha growth. The results indicated that glucose and peptone were optimal carbon and nitrogen for Lactarius deliciosus;MgSO4, CuSO4 and VB2 promoted hypha growth; FeSO4 and CoCl2 had inhibition effects. The orthogonal test concluded the optimal recipe contained glucose of 20 g/L, peptone of 1 g/L, KH2PO4 of 0.3 g/L, MgSO4 of 0.3 g/L, VB2 of 2 mg/L, and agar of 20 g/L, with original pH value adopted. After optimization, growth index of hyphae cultured at 28 ℃ was 4 055.9.采用固体培养的方法,研究不同碳源、氮源和无机盐营养因子对松乳菇菌丝的影响。通过观察菌丝密度和计算菌丝生长指数筛选出最适合松乳菇菌丝生长的培养基配方。结果表明:松乳菇的最适碳、氮源分别为葡萄糖与蛋白胨;MgSO4、CuSO4、VB2促进菌丝生长,FeSO4、CoCl2则有较明显的抑制作用。正交试验,确定松乳菇菌丝生长的最佳培养基配方为:葡萄糖20 g/L,蛋白胨1 g/L,KH2PO40.3g/L,MgSO40.3 g/L,VB22 mg/L,琼脂20 g/L,pH自然。经过优化以后,在28℃下培养,菌丝生长指数为4 055.9。
