烤烟湿润穴盘育苗技术是一种新型的与营养袋假植育苗截然不同的育苗技术。烟苗生长于装填有无土基质并被分隔成小室的泡沫塑料育苗盘中 ,育苗盘孔穴底部开口且悬空放置 ,利用“空气整根”作用 ,可显著增加侧根数量 ,提高根系活力 ,促进烟苗生长发育 ,有效控制苗期病、虫、草害的发生 ,达到培育整齐、健壮烟苗的目的。该育苗技术在漂浮育苗的基础上简化了育苗条件和工序 ,具有投资少、成本低、操作简便、节省劳力的特点 ,符合云南省生产实际 ,具有较高的推广应用价值。 Flue-cured tobacco wet tray culture technology is a new type of nursery seedlings with nursery bags different from the nursery bags. Tobacco seedlings grow in foam plastic seedling trays filled with soil-free substrate and separated into cells. The bottom of nursery tray holes are open and placed in suspension. By using “air whole root” effect, the number of lateral roots can be significantly increased, the root activity can be increased, Miao growth and development, the effective control of seedling disease, insects, grass damage occurs, to cultivate neat, robust tobacco seed purposes. The seedling raising technique simplifies the seedling raising conditions and processes on the basis of floating nursery and has the characteristics of low investment, low cost, simple operation and labor saving, which is in line with the actual production in Yunnan Province and has a high popularization and application value.
