蔬菜育苗前一般都要进行催芽。电热催芽缸制作容易,成本较低,催芽效果好,适合农户使用。其制作方法如下: 一、原材料外桶直径30厘米、高40厘米的废薄铁桶(或木桶)一个;市售300瓦“热得快”电热器一只;级外棉或旧棉絮若干;棒状温度计一只;内桶高28厘米,上口直径10厘米,下底直径15厘米,腰高14厘米,外、内桶大小也可根据需要而定。二、安装将内桶底部中间位置开一直径约3.5厘米的圆孔,用锡把“电热器”焊入圆孔内,导线向外,再把外桶底部凿开,引出导线,然后向外桶与内
Vegetable nursery generally have to be sprouting. Electrothermal germination cylinder production easy, low cost, good germination effect, suitable for farmers to use. The production method is as follows: First, the outer diameter of the raw material barrel 30 cm, 40 cm high scrap iron drum (or barrel) a; commercially available 300-watt “hot fast” electric heater; a few extra cotton or old cotton ; Stick thermometer a; barrel 28 cm high, the diameter of 10 cm, the bottom diameter of 15 cm, 14 cm waist height, the inner barrel size may also be required. Second, the installation of the middle of the bottom of the barrel to open a diameter of about 3.5 cm hole, with the tin to the “electric heater” welded into the hole, the wire outward, and then open the bottom of the outer barrel, lead wires, and then to the outer barrel With inside
