为了获得烟草漂浮育苗适用性好、商业成本低的新型基质配方以代替不可再生的草炭，用腐熟小桐子壳、蛭石与膨化珍珠岩等按不同比例混合，研究不同基质配方对烟种出苗期、出苗率、苗高、成苗期、苗色等育苗质量指标与成品商用基质进行对比育苗试验。结果表明，处理A3（腐熟的小桐子壳∶膨化珍珠岩∶蛭石=60∶20∶20）和A4（腐熟的小桐子壳：膨化珍珠岩∶蛭石=70∶15∶15）配方育苗效果与商品基质差异最小，具备开发为烟草漂浮育苗基质的潜力。

In order to obtain a new type of seedling breeding substrates with good applicability and low cost in Nicotiana tabacum L. floating seeding system instead of non-renewable peat substrate,decayed Jatropha hull,ver-miculite,expanded perlite were mixed. According to different mixing ratio,it compared the emergence period,emer-gence rate,seedling height,seedling formation period,seedling colors in different treatment with commercial seed-ling breeding substrates. The results showed that sample A3(decayed Jatropha hull∶expanded perlite∶vermiculite=60∶20∶20)and A4(decayed Jatropha hull∶expanded perlite∶vermiculite=70∶15∶15)seedling quality were closed to commercial seedling breeding substrates,which could be a good potential material of tobacco seedling breeding substrates.
