Abstract Evergreen broad-leaf forest was the zonal vegetation of Fujian province, however, in the development of edible fungus industry, plenty of it were destroyed for deficient forest. Probing into the technology of altering deficient forest of natural secondary broad-leaf forest to professional forest of edible fungus, which was important to settle contradiction between fungus and secondary broad-leaf forest and problem of soil erosion. Based on experiment of artificial measures promoting regeneration and improvement of directional silviculture of professional forest of edible fungus, results showed that for the alteration of secondary broad-leaf forest, its investment was sparing, forest maturity was ahead of schedule, period of growth was short, and economic benefits were considerable. Volume amount of the eighth year reached 92 1m3/hm 2, 78 3t/hm2 of edible fungus material could be offered, and the rate of devotion to yield was 1∶13 9. The measures of artificial alteration ad favorable eco-benefits of soil and water conservation and function of enhancing soil fertility etc., and which had not harmful effects to species constitute of community. So the measures of closing hillside for erosion control, selecting excellent seedling of objective trees, clearing weed, cirrus and non-objective forest away, cutting too high stump down, selecting vigorous branches and replanting at space in forest were effective to directional silviculture natural deficient broad-leaf forest to professional forest of edible fungus.
