摘 要: 以青榨槭、三角枫、茶条槭、青枫为试验树种,用炭化稻壳、泥炭土、珍珠岩、蛭石为原料,按照不同的配比制成9种基质进行网袋容器育苗,各基质上生长容器苗性状指标苗高、地径、一级侧根数、单株生物量、质量指数均存在极显著差异。运用多目标决策法筛选出培育4树种容器苗的最优基质体积比是V泥炭土∶V炭化稻壳=5∶5。 Taken Ace rdavidii Franch, A. buergerianum Miq, A. ginnala Maxim and A. palmatum Thunb as experimental ma- terials, nine matrix mixed with carbonized rice husk, peat soil, perlite and vermiculite by different ratio were screened for container seedling raising. The results showed that the seedling height, ground diameter, the primary lateral root number, the second lateral root, individual biomass and mass index of container seedlings grew on different matrixes were significant different. The optimal formula of matrixes for container seedling raising of 4 species was 50% carbonized rice husk plus 50% peat soil by using multi-objective decision method.
