摘要
以蔗渣、树皮、锯末、咖啡壳、珍珠岩等为原料,按照一定比例配制5种基质(充分发酵的蔗渣、森林土+珍珠岩(各50%)、充分发酵的松树皮(60%)+锯末(40%)混合物、充分发酵的咖啡壳、充分发酵锯末),以森林土为对照,探索不同育苗基质对降香黄檀苗木生长的影响,采用多目标决策中的一维比较法进行最优基质的评价。结果表明:以充分发酵的蔗渣为基质培养的降香黄檀苗木在苗高、地径和侧根数量等生长指标均显著优于其他育苗基质;综合评价值为0.5326,排名第1,可推荐作为生产中降香黄檀育苗的基质。
With tree bark, sawdust, bagasse, coffee shell, and perlite as raw material, according to certain proportion distribution of 6 kinds of substrate,contrast to forest soil, to study of different substrate on the influence of the Dalbergia odorifera T. Che seedling growth. Results showed that in the matrix 1, seedling height, ground diameter and number of lateral root were significantly better than the other ratio of substrate, nursery had obvious effect ;it ranked second by comprehensive evaluation of the multi objective and deci- sion comparison method;seedling utility best, can be recommended as the D. odorifera T. Che nursery substrates.
