摘　　要：通过人工接种试验,设置4种不同栽培基质,探索不同基质条件下,干巴菌侵染云南松幼苗形成菌根的影响。结果表明,不同基质条件下干巴菌侵染云南松幼苗形成菌根的侵染率、菌根数以及根系长存在显著差异,其中,以C3(蛭石)和C4(珍珠岩:蛭石:红土=1:1:1)最好,侵染率分别为100%和80%;C1(珍珠岩)最差,侵染率仅为10%。Using four different cultivation substrates through artificial inoculation experiment, effects on formation of mycorrhiza Thelephora ganbajun infection on Pinus yunnanensis seedlings were explored. The results showed that there were several signifi- cant differences in term of infection rate, mycorrhizal individual number and root length under different substrates. The best consequence was obtained under condition of C3 （vermiculite） and C4 （pertite： vermiculite： red soil=l：l：l）, with infection rates of 100% and 80%, respectively, and the worst consequence was obtained under condition of C1 （perlite）, with an infection rate of only 10%.
