摘  要:
为培育出优质高产的杉木,满足我国对木材的需求,对不同造林密度杉木幼林的生长发育状况进行了实地调查研究。调查表明:杉木幼林最优的造林密度为3 300株·hm-2,平均树高、平均胸径、蓄积量、单株材积分别达9.78 m、10.88 cm、238.22 m3·hm-2、0.070 9 m3。调查结果可为杉木幼苗人工林培育提供技术支撑和理论参考。

摘  要:
In order to develop optimal-quality and high-yielding Cunninghamia lanceolata,meet the demand for wood,growth of young Cunninghamia lanceolata plantation at different planting densities were investigated. Test shows that the optimal density of young forest to Cunninghamia lanceolata is 3 300 plants·hm-2,the mean tree height,stem diameter,volume,individual volume is 9. 78 m,10. 88 cm,238. 22 m3·hm-2,0. 070 9 m3,respectively;test data can provide technical support & theory reference for plantation cultivation of Cunninghamia lanceolata seedlings.
