东南石栎容器育苗的基质筛选

Matrix Selection on Culturing Container Seedlings of Lithocarpus harlandii

通过对不同基质配方对东南石栎高生长、地径、高径比、苗木地上及地下部分干重的比较,研究了不同基质配方下东南石栎容器苗的苗木质量指数,从而筛选出最佳基质配方。研究表明:8个不同配方中以泥炭土∶珍珠岩∶锯屑为3∶1∶1的配方最适于东南石栎苗的生长。

Based on the comparison and analysis on the grwoth of height,ground diameter,ratio of height to diameter,dry weight of ground and underground parts of seedlings Lithocarpus harlandii,different matrix formulations were manipulated.Seedling quality indices of the seedlings cultured from different matrixes were calculated to select the best matrix formulation.The resuls showed that the formulation of peat soil,perlite,sawdust(3∶1∶1) was the best one.
