摘要
根据杉木中幼林占有比重大的特点,选择其中立地条件好的优良种源林或无性系造林的中幼林分,通过抚育间伐以培育成大径林,经3a的检测结果表明,间伐后林分每公顷立木蓄积年均生长量达到15m3以上。
The proportion of middle and young forests in the TBCuninghamia lanceolata forests of Guanshan Forest Farm is great. According to the characteristic,the farm selected good provenance forests and clonal forests in its middle and young forests to breed large diameter timber by improvement felling since 1999. Through 3 years of survey the results showed that the average annual growth of volume amounted to more than 15 m^3/hm^2.
