Abstract:

Experiment was established to study the impacts of site management on productivity of multiple generation plantations of Chinese fir.Five treatments(site management schemes) were applied at the harvested site of the first generation of Chinese fir plantation.The second-generation plantation was established at the harvested site and observations were made one year after plantation.Results indicated that:(1)BL3BM0 was the most favorable treatment for the growth of Chinese fir and most unfavorable for the ground vegetation.The Chinese fir with treatments BL2BM0 and BL2BM1 had similar growth to each other, indicating that clearance burning had no significant effect on the growth of Chinese fir for the first year, but the burning significantly reduced the biomass production of the ground vegetation.(2)The total biomass production of one-year-old Chinese fir stand varied with treatments in a same way as the biomass production of the ground vegetation.The biomass of ground vegetation was prominent in the total biomass production of 1-year-old Chinese fir stand.

Key words: Chinese fir plantation, Multi-generation management, Site management
