我区春季茄果类蔬菜移苗和瓜豆类蔬菜播种育苗大多在普通塑膜小棚阳畦内进行。这种小棚制作简单、投资少、管理方便。但从多年实践看,它抵御2—3月寒潮连阴雨的能力差,移苗成活率和播种出苗率低,往往造成大量损苗烂种,影响市场供应。为了摸索出一种投资少、管理方便、抵御寒潮低温阴雨,而使育苗安全可靠的简易保护地形式,我们于1983年春季试制一种矮小双棚,并进行了与普通小棚育苗的对比试验。
My area of spring solanum vegetables and seedlings of melons and vegetables planting seedlings are mostly in the ordinary plastic film canopy Yang Yang within. This shed makes simple, less investment, easy management. However, from many years of practice, it is resistant to cold spells in February-March with poor rain-fed ability. The survival rate of transplanted seedlings and seedling emergence rate is low, which often results in a large number of seedlings losing seed and affecting the market supply. In order to explore a less investment, management convenience, to resist the cold and rainy cold, leaving seedlings safe and reliable simple form of protection, we in the spring of 1983 to trial a small double-shelled, and compared with ordinary shed nursery experiments .
