摘要
采用不同播种时间、密度、营造林方式对观光木进行了栽培和营造林试验,结果表明:3月初是观光木播种育苗最佳时期;芽苗移栽平均苗高是直播苗的3.18倍,平均地径是直播苗的2.07倍;采用容器苗造林,成活率达95%以上,一年后高生长达112.1 cm,是裸根苗的1.77倍,地径是裸根苗的2.04倍;密度控制幼苗期以64株/m2为最佳,苗木合格率可达90.37%。
The cultivation and afforestation experiments of Tsoongiodendron odorumwere carried on with using different sowing time,planting density and afforesting ways,and the results showed that the best sowing period of T.odorumwas in early March,the average height of transplanted bud-seedling was 3.18 times to live seedling and average diameter was 2.07 times.The survival rate of container seedling afforestation was more than 95%,its height was up to 112.1cm after one year and 1.77 times and its ground diameter was 2.04 times the bare-root seedling.The density control of T.odorumin seedling stage was 64 plants per square meter for the best and it＇s seedlings pass rate was up to 90.37%.
