摘　　要：该研究选用林业废弃物、牛粪和苗圃土壤为基质原料,采用重心混料设计法进行复配,以苗圃土壤为对照,研究不同配方基质理化性质及其对落叶松幼苗生长的影响。结果表明:在苗圃土壤中添加林业废弃物或者牛粪,改善了基质的理化性质,更适于落叶松容器育苗,而且可以降低运输成本;以23%牛粪+77%苗圃土或(23%~35%)林业废弃物+(65%~77%)苗圃土为基质,落叶松幼苗各项生长指标均显著优于100%苗圃土。This research work selected forestry waste,cow dung,and nursery soil as raw materials for substrate distribution,using a center-of-gravity mix design with nursery soil as the control.Research investigated the physicochemical properties of different formulated substrates and their effects on the growth of larch seedlings.The results showed that add forestry waste or cow dung to the nursery soil helps to improve the physicochemical properties of the substrate,which was more suitable for larch container nurseries and reduces transportation costs.(23%~35%)forestry waste+(65%~77%)nursery soil and 23% cow dung+77% nursery soil were the best,the growth indexes of larch seedlings were significantly better than those of 100% nursery soil.
