紫薇容器育苗基质配方筛选研究

摘要

Experiments were conducted on 7 different substrates formula for container seedling cultivation ofLagerstroemia indica. And seedling quality was estimated by multi-objective decision method. The result demonstrated that the optimal formula for container seedlings cultivation ofL. indica was peat : vermiculite = 2:1, followed by peat : vermiculite : perlite = 5:4:1 and nursery soil. Comprehensive estimations on cost and seedling quality resulted that nursery soil was recommended for container seedling cultivation ofL. indica.%以泥炭、蛭石、珍珠岩等为基本材料按7种不同配比开展紫薇（Lagerstroemia indica）容器苗基质配方试验实验，采用多目标决策法对紫薇容器苗苗木品质进行综合评价。结果表明：泥炭：蛭石=2：1的基质配比为培育紫薇容器苗最佳基质组合，而泥炭：蛭石：珍珠岩=5：4：1的基质配方及仅由圃地土组成的基质配方分别排在第2及第3位。综合考虑育苗成本和育苗质量等因素，仅由圃地土组成的基质可作为优先推荐的基质类型应用于紫薇容器苗生产。
