摘　　要：对杉木容器苗与裸根苗营建的幼林早期生长量测定,结果表明,造林生长第1年时,杉木裸根苗幼林树高、地径生长量相对于杉木容器苗幼林树高、地径分别增长了28.6%和56.8%,杉木裸根苗幼林树高、地径增长量相对于杉木容器苗幼林树高、地径分别增长了26.0%和66.7%;造林生长第2年时,杉木裸根苗幼林树高、地径生长量相对于杉木容器苗幼林树高、地径分别增长了6.2%和14.8%,杉木容器苗幼林树高、地径增长量相对于杉木裸根苗幼林树高、地径分别增长了4.0%和3.1%。This study examines the early growth performance of young forests established using container seedlings and bare-root seedlings of Cunninghamia lanceolata.The results indicate that in the first year of afforestation,the height and basal diameter growth of young bare-root seedlings increased by 28.6%and 56.8%,respectively,compared to container seedlings.Similarly,the height and basal diameter growth of bare-root seedlings increased by 26.0%and 66.7%,respectively,compared to container seedlings in young forests.In the second year of afforestation,the height and basal diameter growth of young bare-root seedlings increased by 6.2%and 14.8%,respectively,compared to container seedlings.Conversely,container seedlings exhibited 4.0%and 3.1%greater height and basal diameter growth,respectively,compared to bare-root seedlings.
