摘　　要：人工针叶纯林成熟林分主伐择伐后,对20株/亩(A)、30株/亩(B)、40株/亩(C)3种不同保存密度林冠下采用赤皮青冈与米槠2年生无纺布营养袋苗造林效果对比,造林2年的生长量调查结果表明:不同保存密度林下套种的赤皮青冈与米槠造林成活率、地径、高度、冠幅4项指标均以A最高,平均造林成活率达96.4%,赤皮青冈平均地径达2.21 cm,平均高达177.7 cm,平均冠幅达106.0 cm;米槠平均地径达2.07 cm,平均高达224.6 cm,平均冠幅达133.6 cm;4项指标大小次序为A>B>C。After the main cutting and selective cutting of mature coniferous pure plantation stands,the afforestation effects of using the 2-year-old non-woven nutrient bag seedlings of Cyclobalanopsis glauca and Castanopsis carlesii under the canopy of 20 trees/mu(A),30 trees/mu(B)and 40 trees/mu(C)with different conservation densities were compared.The results of the 2-year growth survey showed that the survival rate,ground diameter,height and crown width of the intercropped Cyclobalanopsis carlesii and Castanopsis carlesii under the forests with different conservation densities were the highest in A.The average survival rate of afforestation is 96.4%.The average ground diameter of Cyclobalanopsis glauca is 2.21 cm;the average height is 177.7 cm,and the average crown width is 106.0 cm;The average ground diameter of Castanopsis carlesii is 2.07 cm;the average height is 224.6 cm,and the average crown diameter is 133.6 cm;The order of four indicators from high to low is A>B>C.
