随着蔬菜工厂化育苗的进展,国内外又出现了用多孔式硬泡沫塑料秧盘育苗的新方法。我们利用从美国带回的一个秧盘作的大白菜育苗试验,获得了较满意的效果。所用秧盘的规格为:长65厘米、宽35厘米、高8厘米,内有200个锥体形的露底孔体(见图1)。采用(石至)石做育苗基质。为了保证秧苗的健壮生长,在基质装入育苗盘之前,首先用1%的福尔马林进行消毒,之后加入一定量的水,使其含水量达到80—85%,最后将基质装入盘孔内压实,使每个孔体的表面呈一个半球形,以利播种。采用精量点播法播种,每个小孔内播1—2粒种子,随之用喷雾器喷水,以手按覆盖物有水溢出
With the progress of vegetable factory nursery, a new method of seedling nursery with porous rigid foam plastic seedlings has appeared at home and abroad. We used the seedlings from the United States brought back a cabbage nursery trials, obtained more satisfactory results. The specifications for the seedlings used are: 65 cm in length, 35 cm in width and 8 cm in height, with 200 cone-shaped open-hole bodies (see Figure 1). Using (stone to) stone nursery substrate. In order to ensure the robust growth of seedlings, before the substrate into the nursery tray, first disinfection with formalin 1%, then add a certain amount of water, the water content of 80-85%, and finally the substrate into the plate Hole compaction, so that the surface of each hole was a hemispherical shape, to facilitate sowing. Sowing seeds by precision on-demand method, 1-2 holes of seeds are punctured in each hole, followed by water spraying with a sprayer and water overflowing by hand covering
