塑料营养土旱育秧虽能培育壮秧 ,但程序繁 ,技术难掌握 ,特别是大面积实施商品化育秧 ,在苗床地的选择、整做、营养土配制、播种、装盘、压盘等方面工序多。为简化操作 ,经试验在播种环节采用湿播法 ,播后采用旱育管理方式 ,表现出省工易操作 ,秧苗素质比较理想 ,这为较大面积商品化育秧打下了良好的技术基础 Although the cultivation of seedlings of plastic nutrition soil dry drought seedlings can grow, but the program is complicated, difficult to master the technology, especially the implementation of commercial nursery large area, in the seedbed selection, the whole make, nutrition soil preparation, sowing, loading plate, Many processes. In order to simplify the operation, wet sowing method was adopted in the sowing stage after sowing test, and dry management was adopted after sowing, which showed that it was easy for workers to operate and the quality of seedling was ideal. This laid a good technical foundation for commercial breeding of large area
