摘　　要：为了筛选出烟草(Nicotiana tabacum L.)漂浮育苗替代基质配方,用腐熟花生壳、河沙、蛭石进行混配,采用配方对比育苗试验方法,研究了不同处理基质的出苗率、成苗质量和烟苗农艺性状差异,并进行了成本分析。结果表明,以腐熟花生壳与河沙体积比8∶2和7∶3的混配配方育苗效果最好,与商品基质差异最小,且成本较低,具备作为烟草漂浮育苗基质的条件。In order to screen for alternative medium of Nicotiana tabacum L. floating seedling system, decayed peanut bran, riversand and vermiculite was mixed. The sprouting rate, maturing seedling rate and agronomic traits of the seedlings was de- termined, and the cost was compared. The results showed that the comprehensive characters of N. tabacum seedlings were the best, the effect was closed to commercial medium when the seedlings were raised in 80% peanut bran＋20% riversand or 70% peanut bran＋30% riversand, which could basely meet the requirements of N. tabacum floating breeding medium.
