电加热温床,是在温室、塑料大棚或阳畦等保护条件下,利用特制的土壤加热电线,通过交流电,经自动控温仪,用电热调节苗床土壤温度。具有设备简单,投资少,成本低,操作简便,增温效果稳定可靠等特点,适于多种花本的播种和扦插育苗。在一般的温室、塑料大棚及小拱棚内均可应用。在普通阳畦或庭院内背风向阳小片空地也可使用。建造电热温床,可用砖砌宽100厘米,长200～800厘米(根据产品型号、电线长度而定),深30厘米的苗床,底部铺5～10厘米的碎石、炉渣作渗水层,再填入3～5厘米厚的蛭石或稻糠灰作保温层。在保温层上按一
Electric heating hotbed is in the greenhouse, plastic greenhouses or sunspots and other protective conditions, the use of special soil heating wire, through the exchange of electricity, the automatic temperature control, with electric heat regulation seedbed soil temperature. With simple equipment, low investment, low cost, easy operation, stable and reliable warming effect, suitable for a variety of flowers of the sowing and cutting propagation. In the general greenhouse, plastic shed and small shed can be applied. In the common sunshine or courtyard leeward sunny small open space can also be used. Construction of electric hotbed, available brick width 100 cm, length 200 ~ 800 cm (depending on the product model, the length of the wire), 30 cm deep seedbed, the bottom shop 5 to 10 cm of gravel, slag for the seepage layer, and then fill Into 3 to 5 cm thick vermiculite or rice bran ash for insulation. Press one on the insulation
