滇西北生态公益林区高山松容器育苗基质配方研究

On Pinus densata seedling substrates of ecological forest in westnorth Yunnan

应用层析分析法和相关分析研究了以云南中甸泥炭为主要基础性物质的10种配方基质对滇西北生态公益林区高山松容器苗生长的影响,结果表明,配方基质对高山松生长有显著影响,灰色关联度最高(Ri=0.8363)的为泥炭、蛭石和珍珠岩等体积混合的配方.基质的理化性质对高山松容器苗的影响主要集中在地下部.

The growth of Pinus densata container seedling with peat substrate （ten types） was studied with method of Analytic hierarchy process （AHP） in ecological forest in westnorth Yunnan. The result showed that significant difference was observed among substrates. The max grey relational grade（Ri） was obtained with peat ： vermiculite ： perlite = 1：1：1 media. The root growth of container-grown seedlings was significantly influenced by physiochemical characters of substrate.
