83年春,我们在原有育苗箱基础上,重新设计了一个160×120×60厘米的柜式育苗箱(图1)。为了充分利用自然光照,箱的三面为玻璃,后面为五合板,前面由八扇四折式的玻璃门组成,可根据育苗盘之大小,决定开门面积,以尽量减少外温的影响。箱内分为五层,层间距为28厘米,每层面积0.72米~2,全箱的使用面积3.6米~2。箱顶设有八个通风孔,可根据要求,扭动圆盘,来调节孔的大小,控制通风量。箱内1～4层(图2),在每层18厘米高处安一个30瓦的日光灯,增强箱内光照强度并做为辅助热源。距底层15厘米高处可安装2～4个100瓦的灯炮
In the spring of 1983, on the basis of the original seedling box, we redesigned a 160 × 120 × 60 cm cabinet (Figure 1). In order to make full use of the natural light, the three sides of the box are made of glass and the back is a pentagonal plate. The front is made up of eight four-folded glass doors. The area of the door can be decided according to the size of the nursery tray so as to minimize the influence of external temperature. The box is divided into five layers, layer spacing of 28 cm, each layer area of 0.72 m ~ 2, the use of the entire box area of 3.6 m ~ 2. The top of the box has eight vents, according to requirements, twist the disc, to adjust the size of the hole, control ventilation. Box 1 to 4 layers (Figure 2), 18 cm high in each layer of a 30-watt fluorescent lamp to enhance the light intensity inside the box and as a secondary heat source. From the bottom 15 cm height can be installed 2 to 4 100-watt bulbs
