为了探求草炭替代基质用于烟草漂浮育苗的可行性,以本地的紫色泥岩为研究对象,对基质理化性质进行分析。结果表明,紫色泥岩基质化学稳定性好、微量元素含量丰富,有机质含量非常少,且运输方便。通过添加有机质、珍珠岩,作为烟草育苗基质替代物,有较好的发展前景。 In order to explore the feasibility of substituting peat substitute substrate for tobacco floating seedling, the local purple mudstone was taken as the research object to analyze the physical and chemical properties of the substrate. The results show that the purple mudstone matrix has good chemical stability, abundant trace elements, very little organic matter, and convenient transportation. By adding organic matter, perlite, tobacco substrate as a substitute for tobacco, there is a better development prospects.
