| 摘 要： | 调查长乐、庆元两个杉木子一代种子园，并按株测定同一无性系在不同郁闭度下的碳氮比。结果表明，杉木种于园郁闭度对产量影响很大。郁闭度太小或过大，小区单产均低。最适宜的郁闭度是0.58~0.66。盛果期的杉木种子园必须及时疏伐。

| 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). |
