Inoculation effects ofSuillus grevillei on Larch seedlings

A large areas of Larch seedlings, including container and bare-root seedlings (new and transplanted seedlings) were inoculated pure inocula that were cultivated by usingSuillus grevillei. Compared with those of control area, all growth indices as rate of emergence, growth(in seedling height, collar diameter and number of lateral branch-root), rate of mycorrhiza inoculum, rate of survival and content of nutrient elements were greatly increased. Therefore,Suillus grevillei is a better and suitable mycorrhizal fungus to larch seedling either in the severe cold mountain area or in the plain region. It should be spread and used in larch cultivation and planting.
