Abstract

Investigation of two F1 seed orchards of Chinese fir at Changle Forest Farm and Qingyuan Forest Farm in Zhejiang Province and determination of carbob-nitrogen ratio of same clone in different canopy densities showed that the effect of canopy density on seed yield had been great, with lower yield per crown in too scarce or too dense canopy densities. In full cone period, the seed orchard should be timely thinned to ensure the best suitable canopy densities (from 0.58 to 0.66).
