摘　　要：为探究经济适宜的育苗方法,通过各地点大棚对比育苗试验与半边田示范开展了烤烟托盘全基质湿润育苗技术示范研究。结果表明:1) 湿润育苗的烟苗根系更加发达,有利于促进大田移栽早生快发。2) 但育苗成本高于漂浮育苗。3) 其中部叶长、上部叶长及上部叶宽优于常规200孔漂浮苗,其增幅分别为23.45%、23.3%及13.6%;能提高烤烟亩产量、亩产值与均价。在水资源丰富的地区湿润育苗值得推广。本研究可为现代集约大棚自动化育苗提供理论参考。In order to explore the economical and suitable seedling raising method, the demonstration study on the whole matrix moist seedling raising technology of flue-cured tobacco tray was carried out through the comparative seedling raising experiment of greenhouse and half field demonstration. The results showed as follows: 1) The roots of tobacco seedlings reared in moist condition were more developed, which was conducive to promoting early growth and rapid growth in field transplanting. 2) The cost of seedling raising was higher than that of floating seedling raising. 3) The middle leaf length, the upper leaf length and the upper leaf width were better than those of the conventional 200-well floating seedlings, and the increases were 23.45%, 23.3% and 13.6%, respectively. It can improve the yield per mu, the output value per mu and the average price of flue-cured tobacco. It is worth promoting moist seedling in the area with abundant water resources. This study can provide theoretical reference for modern intensive greenhouse automatic seedling raising.
