摘要
为对比2种育苗方式培育的杉木轻型基质容器苗木生长及造林效果,进行了杉木扦插容器苗与杉木实生容器苗木及造林生长测定.结果表明:在造林生长10个月,杉木扦插容器苗幼林树高、地径、高径比、树高同比增长量和地径同比增长量分别为:0.98 m、18.3 mm、53.3、73.1 cm和14.4 mm;杉木实生容器苗幼林树高、地径、高径比、树高同比增长量和地径同比增长量分别为:0.91 m、18.2 mm、50.0、67.8 cm和14.6 mm.综合对比:杉木扦插容器苗木及造林均表现最优.
Abstract
To compare the growth and afforestation effects of two seedling cultivation methods for light substrate container seedlings of Cunninghamia lanceolata,this paper conducts growth measurements of container seedlings for Cunninghamia lanceolata cuttings and actual container seedlings for Cunninghamia lanceolata afforestation.The results indicate that after 10 months of afforestation growth,the height,ground diameter,height to diameter ratio,and year-on-year growth in height and ground diameter of young Cunninghamia lanceolata container seed-lings were 0.98m,18.3mm,53.3cm,73.1cm,and 14.4mm,respectively;The height,ground diameter,height to di-ameter ratio,and year-on-year growth in height and ground diameter of young Cunninghamia lanceolata container seedlings were 0.91m,18.2mm,50.0,67.8cm,and 14.6mm,respectively.Comprehensive comparative analysis shows that the container seedling stage and afforestation growth of Cunninghamia lanceolata cuttings are better than those of Cunninghamia lanceolata seedlings.Comprehensive comparison:Cunninghamia lanceolata cuttings,container seedlings,and afforestation all performed the best.
