摘要
通过对１８２块杉木标准地的调查和不同造林时期栽培技术分析评价，总结出了“以立地控制，遗传控制，密度控制为中心，实行集约经营，定向培育”的杉木速生林栽培模式。使庆元林场万亩杉木速丰林平均年生长量达到１２．３ｍ～３／ｈｍ～２，超过了林业部速丰林生长指标。
Investigations on 182 sample plots of Cunninghamia lanceolata stands and analysis on cultivation technique at different forestation take summarized fast-growing cultivation mode of site control,genetic control, density contrlo,intensive management and orientation cultivation. The mean annual increment of 6666.67 hectares Cunninghamia lanceolata stands in Qingyuan Forest Farm reached 12.3m^3/hm^2,which surpassed increment index of standard of forestry ministry.
