摘　　要：为明确适合恩施烟区井窖式小苗移栽的育苗盘密度,采用漂浮育苗的方法,研究了153孔、200孔、288孔和500孔4种育苗盘密度对烟苗生长发育及烟叶产质量的影响。结果表明,153孔、200孔和288孔3种育苗盘育出的烟苗素质较好,均能满足井窖式小苗移栽的要求,但153孔和200孔2种育苗盘育苗成本相对较高;500孔育苗盘育苗成本最低,但育出的烟苗素质最差。总体而言,288孔育苗盘育苗成本相对较低、经济效益最好,明显减工、降本、增效,更符合恩施烟区育苗实际,值得在生产上推广应用。In order to determine the suitable seedling density on nursery trays for Enshi tobacco producing area for the Tobacco Plantlet Transplanting In Well Cellar（TPTWC） using floating seedling cultivation,we tested nursery trays with 153 holes,200 holes,288 holes and 500 holes for their effects on seedling growth and development,tobacco yield and quality.The results showed that nursery trays with 153 holes,200 holes and 288 holes were all able to produce tobacco seedlings with good quality,healthy enough to meet the requirements of TPTWC.The 153 hole and 200 hole trays however,increased the cost of seedling productio.Seedling cultivation with the 500 hole tray had the lowest cost but the quality of tobacco seedlings was the worst.Overall,the 288 hole nursery tray had relatively low nursing cost,the best economic benefit,significantly less labor employment,reduced production cost,increased production efficiency,and more in line with the situation in Enshi.It is worth of popularizing and applying in tobacco production.
