摘　　要：To understand the roles of charcoal and ectomycorrhizal fungi(ECMF)on tree growth,which relates to the rehabilitation of forest ecosystems after forest fires,two experiments were set up in this study,the first was to determine the correct amount of charcoal for Japanese larch(Larix kaempferi Sarg.)seedling growth by applying oak charcoal to basic soil medium at ratios of 1:1,1:2,1:4 and 1:8 by volume.The second experiment investigated the combined effects of four types of charcoal:derived from oak wood,husks of buckwheat,rice and activated charcoal of larch wood,and two types of ECMF:Pt(Pisolithus tinctorius Pers.)and Ec(Pt+Rhizopogon spp.+Laccaria spp.+Scleroderma spp.)on the growth of Japanese larch seedlings.Our results show that growth was significantly stressed by large amounts charcoal applications.There were significant variations among the four types of charcoal on growth.We concluded that the addition of charcoal was the critical factor that influenced larch growth and ECMF formation.Rice charcoal and Ec stimulates the growth and nitrogen uptake of Japanese larch seedlings,thus the most suitable fungus and charcoal for practices is Ec-rice charcoal(1:8 charcoal to basic soil).
