摘　　要：以烤烟品种K326为试验材料,以常规漂浮育苗为对照(CK),通过托盘育苗和大田栽培试验,研究了湿润育苗过程中向基质配施不同比例(5%、10%、15%、20%)含水溶性氮的缓释肥处理(Q_(5)、Q_(10)、Q_(15)、Q_(20))对烤烟幼苗素质、烤烟生长及烟叶产质量的影响。研究结果表明:缓释肥处理可以改善烟苗的农艺性状,提高烟苗的叶片叶绿素含量和生物量,从而提高烟苗的素质;Q_(15)处理培育的烟苗在大田栽培后其烟叶产量比对照提高了6.02%。总之,在4种缓释肥处理中,以Q_(15)处理的湿润育苗效果最佳。The flue-cured tobacco variety“K326”was selected as experimental material,and the tray seedling and field test methods were used to carry out the experiment.The effects of different proportions(5%,10%,15%and 20%)of water-soluble nitrogen slow-release fertilizer(Q_(5),Q_(10),Q_(15)and Q_(20))on seedling quality,growth,yield and quality of flue-cured tobacco were studied.The results showed that the slow-release fertilizer treatments could improve the agronomic traits of tobacco seedlings,increase the chlorophyll content and biomass of tobacco leaves,and improve the quality of tobacco seedlings.In conclusion,among the four slow-release fertilizer treatments,Q_(15)had the best effect on tray seedling growth.
