摘　　要：为减少传统基质中草炭、蛭石、膨胀珍珠岩等不可再生资源的开发,降低烤烟育苗成本,利用耕作层土壤、火土、农家肥、营养液肥料的混合物作为烤烟育苗基质进行了漂浮育苗试验。结果表明,在土壤中加入等比例火土、30%农家肥、2%~2.5%营养液肥料作为烤烟育苗基质,其理化指标接近传统基质,能培育出健壮烟苗,出苗率达84.57%,成苗率达97.53%,烟苗生长和农艺性状与传统基质相比差异较小,每池成本较传统基质节省48元。To decrease the exploitation of the non-renewable resources as peat, vermiculite, expanded perlite used in traditional medium, and reduce the seedling cost of tobacco, tobacco float seedling test is done with medium containing mixture of tillage layer soil, burnt soil, farmyard manure, and nutrient fertilizer. The result showed that the tobacco seedling medium with 34% tillage layer soil, 34% burnt soil, 30% farmyard manure, and 2%–2.5% nutrient fertilizer, was close to the traditional medium concerning physicochemical indexes and could produce robust tobacco seedlings. The tobacco seedling emergence rate reached 84.57%, and the qualified seedling percentage reached 97.53% with this new medium. There are small difference between the new and the traditional medium on growth and agronomic trait. And the seeding cost was saved 48 yuan per pool compared with the traditional medium.
