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％.
Abstract
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 seed-lings.Conversely,container seedlings exhibited 4.0％and 3.1％greater height and basal diameter growth,respectively,compared to bare-root seedlings.
