摘要
对1 a生欧洲三倍体山杨组培苗进行苗高和地径生长节律调查,用Mitscherlich生长方程进行了拟合,揭示出苗高和地径随时间的变化规律.通过对不同生根量的观测统计分析和LSR检验,确定出地径的生长量以生根5条和6条为最佳,苗高生长量以4条、5条、6条为最佳,生根2条和3条的苗木在地径和苗高上都比较差.
To investigate the growth regular of seedling height and diameter of one-year group seedling of Populus tremulagigas with using Mitscherlich equation. The seedling height and diameter changed with the time. The increment of diameter's taking roots take five roots and six roots as the best through different statistics analysis and LSR, the increment of seedling height take four roots, five roots, six roots as the best, taking roots two and three are worse on the diameter and seedling height.
