不同育苗方式的2年生杉木幼林生长对比分析
Comparative analysis of the growth of two-year-old Cunninghamia lanceolata saplings under different seedling cultivation methods
摘要
Abstract
To investigate the growth differences of 2-year-old Cunninghamia lanceolata saplings cultivated by different seedling raising methods,the seedling raising method with the best growth performance under the same site conditions was selected.In this experiment,Cunninghamia lanceolata seedlings of the first grade were planted using containerized cuttings,containerized seedlings,and bare-root seedlings.Three sets of replicated experimental plots were laid out horizontally on the same slope with basically the same site conditions.Variance analysis and interval distribution methods were used to analyze the tree height,ground diameter,and height-to-diameter ratio of the seedlings under different seedling raising methods.The results showed that the 2-year-old seedling saplings of Cunninghamia lanceolata grown from bare-root seedlings had the best growth in tree height and ground diameter.The tree height and ground diameter of these saplings increased by 6.6%and 4.1%respectively compared to the total average tree height and ground diameter of the saplings from the 3 different seedling cultivation methods.The height-to-diameter ratio of 2-year-old Cunninghamia lanceolata saplings from each seedling cultivation method,from largest to smallest,were:containerized cuttings(53.6)>bare-root seedlings(51.6)>containerized seedlings(46.2).By conducting a comprehensive comparison using growth variance analysis and interval distribution,the seedling of Cunninghamia lanceolata grown from seeds with bare roots performed the best.Overall,considering both seedling growth performance and cost-effectiveness in cultivation,bare-root seedlings of Cunninghamia lanceolata are recommended as the priority choice in afforestation practice,thereby laying a foundation for the establishment of high-quality stands.关键词
