摘要
实验表明:在Ⅲ类立地的杉木迹地上营造马尾松,每公顷保留1200-1500株的杉木萌芽条,能起到促进马尾松幼林生长的作用;至7-8年间伐时每公顷可获纯利3800元。该类型幼林在7年生时应进行一次高强度(40%-50%)的间伐,以保证马尾松的生长不受影响。
The experiment indicates that to plant Pinus massoniana on Ⅲ- type sites of blanks of fellingCunninghamia lanceolata the measure of reserving 1200-1500 C. lanceolata coppice shoots per ha canpromote the growth of young P. massoniana forests and the pure profit of 3800 yuan(RMB)can be obtainedfor the thinning each ha during 7-8 years.The high-intensity(40-50%)thinning should be conducted forthis type of young forests at the age of seven years in order to prevent the growth oF P. massoniana from beingaffected.
