摘　　要：为探究不同育苗方式杉木培育的苗木差异,2022年12月开展杉木扦插裸根苗、杉木扦插容器苗、杉木实生裸根苗和杉木实生容器苗生长量、生物量测定,结果表明:杉木扦插裸根苗和杉木实生裸根苗,相对4种不同育苗方式杉木苗高、地径和总生物量总数平均值高出45.0%、25.5%,38.3%、14.9%和56.1%、33.3%;杉木扦插容器苗和杉木实生容器苗,相对4种不同育苗方式杉木苗高、地径和总生物量总数平均值低出52.1%、53.9%,30.6%、42.4%和46.2%、119.2%;依据苗木质量指数(QI)值评价结果分析,杉木扦插裸根苗苗木质量最优,依次是杉木实生裸根苗、杉木扦插容器苗和杉木实生容器苗,通过相关性分析4种不同育苗方式杉木苗生长量和生物量均呈正相关。In order to explore the differences of seedlings cultivated by different seedling raising methods of Chinese fir,In December 2022,the growth and biomass of Chinese fir cuttage bare root seedlings,Chinese fir cuttage container seedlings,Chinese fir seedling bare root seedlings and Chinese fir seedling container seedlings will be measured,The results show that:Cunninghamia lanceolata cuttage bare root seedlings and Cunninghamia lanceolata seedling bare root seedlings,Compared with the average values of seedling height,ground diameter and total biomass of four different seedling raising methods of Chinese fir,the average values are 45.0%,25.5%,38.3%,14.9%and 56.1%,33.3%higher;Chinese fir cuttage container seedlings and Chinese fir seedling container seedlings,Compared with the average values of seedling height,ground diameter and total biomass of four different seedling raising methods of Chinese fir,the average values are 52.1%,53.9%,30.6%,42.4%and 46.2%,119.2%lower;According to the evaluation results of seedling quality index(QI),Cunninghamia lanceolata cutting bare root seedlings have the best quality,The order is the bare root seedling of Chinese fir,the container seedling of Chinese fir cutting and the container seedling of Chinese fir,Through correlation analysis,there was a positive correlation between the growth and biomass of Chinese fir seedlings in four different seedling raising methods.
