摘 要:以苗龄约160d的云南松苗木为试材,采用L9(34)正交设计开展无纺布容器规格、基质和追肥3因素3水平的苗木培育试验,于苗龄190d和250d时测定地径和苗高,分析了试验因素的水平及其组合对苗木生长的影响。结果表明:苗龄190d和250d时,苗木的平均地径和苗高分别为1.19~1.72、1.89~2.32mm和1.36~3.40、3.11~4.09cm,2个苗龄的不同处理组合间地径和苗高均呈现极显著差异(P〈0.01)。容器规格、基质配比和根博士浓度对2个苗龄阶段的地径、苗高均有极显著影响(P〈0.01),云南松苗木生长对空间和养分具有动态的变化需求;6份森林土与3份碳渣和1份珍珠岩混合为基质有利于云南松苗木生长。苗高与地径具有y=1.232 2x+0.801 3的一元线性相关。Taking 160-day-old seedlings of Pinus yunanensis as test materials, and the L9(3^4) orthogonal design was applied to implement cultivating the seedling experiment of three factors (each factor including three levels) which of non-woven fabric container size, matrix and fertilization in order to understand effects of factorial levels and their treatment combinations on seedling growth,basal diameters and seedling heights for 190-day-old and 250-day-old. The results showed that mean diameters and seedling heights were 1. 19-1. 72,1. 89-2. 32 mm and 1. 26-3. 40,3. 11-4. 09 cm for 190-day-old and 250-day-old seedlings. There were significant differences of basal diameters and seedling heights between treatment combinations for two age stages of the seedlings (P〈0. 01). There were also presented significantly different effects of basal diameters and seedling heights between the factorial levels of container size, matrix and fertilization (Root Doctor, a kind of water soluble fertilizer) solution concentration for two age stages' seedlings (P〈0. 01) ,which indicated that it had dynamic requirements of the spaces and nutrients with Pinus yunnanensis seedling growth;the mixed matrix of forest soil, carbon residues and perlite which were portions of 6 :3 : 1 could improve seedling growth. The seedling height and basal diameter had a linear correlation of y= 1. 232 2x+0. 801 3.
