烤烟漂浮育苗中目前所用的基质主要为草炭基质。配制草炭基质所需的原材料草炭，在自然界的储量小且不可再生。由于过量开采，草炭已面临枯竭的问题。为实现烟叶生产可持续发展，探索新型烤烟育苗基质，摆脱对草炭基质的依赖成为了亟待解决的问题。本研究试图用蚓粪基质替代草炭基质，并进行试验研究。结果表明，蚓粪基质容重大于草炭基质；鲜质量、茎高、茎围蚓粪基质比草炭基质分别多出0.4 g、2.2 mm、1 mm；生育期相当，平均为113 d。两种基质所育烟苗的素质相当，蚓粪基质可以取代草炭基质进行烤烟育苗。该结果为蚓粪基质在烤烟漂浮育苗中的大面积推广提供了参考依据。

At present, the dominant medium used in tobacco floating system is nonrenewable peat which has little reserves naturally and is of great significance in maintaining eco-system balance. But excessive exploitation makes it deplete gradually. In order to maintain sustainable development of tobacco production, the potential on vermicompost medium as a new substitute for peat was investigated in this study. The results showed that bulk density of vermicompost medium was higher than those of peat. Fresh weight, stem height and stem girth of seedlings were 0.4 g, 2.2 mm, 1 mm more than those peat, respectively. Average growth period was 113 days. Seedlings quality by two mediums was very similar. Those results suggested that the vermicompost can replace peat as flue-cured tobacco seedling medium in float system.
