摘要
为贵州烤烟生产上适宜育苗基质的选择提供参考依据,选择大方基质、金福基质、大兴基质和瑞安基质4种育苗基质,采用漂浮育苗方法,研究不同育苗基质对烤烟漂浮育苗烟苗生长的影响。结果表明:4种基质所育烟苗各生育期的叶色均为浅绿,金福基质出苗最早,大兴基质出苗最晚,大兴基质成苗最早,大方基质成苗最晚;4种基质最终出苗率均>90%,依次为大兴基质>金福基质>瑞安基质>大方基质。4种基质育苗的出苗率、成苗率和烟苗素质等均达烤烟生产技术要求,以金福基质育出的烟苗素质最好;各种基质均可进一步优化其配方与工艺,以进一步提高基质的吸水及松散性能。
In order to provide a reference for the selection of suitable seedling substrates in the flue-cured tobacco production in Guizhou,four kinds of seedling substrates were selected,i.e.Dafang substrate,Jinfu substrate,Daxing substrate and Ruian substrate.And the effects of different substrates on the growth of flue-cured tobacco seedling were studied by floating seedling cultivation method.Results:The leaf color of tobacco seedlings on the four kinds of substrates was light green at each growth stage.Seedlings of Jinfu substrate treatment came to emergence stage the earliest,while that of Daxing substrate came the latest.Seedlings of Daxing substrate treatment came to maturity stage the earliest,and Dafang substrate turned out to be the latest.The final emergence rates of the four kinds of substrates were all over 90%,following the sequence of Daxing substrate>Jinfu substrate>Ruian substrate>Dafang substrate.The seedling emergence rate,seedling-forming rate and tobacco seedling quality of the four substrates met the requirements of flue-cured tobacco production,Jinfu substrate was of the best seedling quality;Various substrates can be further optimized in formulations and processes to further improve the water absorption and loosening properties of the substrate.
