浅水湿润托盘育苗技术研究初报

The Technique of Tobacco Moist Tray Seedling Nursing in Shallow Water

针对漂浮育苗技术实际应用中存在的问题,以漂浮育苗为对照,研究浅水湿润托盘育苗技术对苗盘温度及烟苗素质等的影响。结果表明,浅水湿润托盘育苗的苗盘温度变化利于烟苗生长,出苗率相当,根系发达,烟苗素质优于漂浮育苗,栽后还苗期较短。同时,浅水湿润托盘育苗需水量较少,较好解决了山区水源缺乏的矛盾。浅水湿润托盘育苗技术具有一定的应用空间。

In order to solve the problems existing in the present floating system for tobacco seeding culture, a technique was in- vestigated of tobacco moist tray seedling nursing in shallow water, taking floating seeding as control. The results shows that temperature of moist tray seeding in shallow water was better for tobacco seeding growth, seeding emergence rate of wich was considerable, well developed root system , tobacco seeding bred was better than floating seeding. What＇s more, less water consumption of seeding was better solved the contradiction of water lack of mountain areas. On the whole, the technique of to- bacco moist tray seedling nursing in shallow water has a certain development space during tobacco seeding.
