冬季,随着气温越来越低,温室大棚如没有适当的保温增温设施会影响大棚作物的生长,以及最后的收成。为了增加棚室温度,广大种植户试用很多方法,如:多层膜保温、电灯补光增温、电热线加温、热风炉加温等,虽然取得了一定效果,但也暴露了其中的很多缺陷,如有的要增加设备、增加费用,有的还存在安全隐患,而 Winter, with the temperature getting lower and lower, greenhouses, such as the lack of proper insulation warming facilities will affect the greenhouse crop growth, and the final harvest. In order to increase the greenhouse temperature, the majority of farmers try many methods, such as: multi-layer insulation, light fill light heating, electric heating wire, hot stove heating, although achieved some results, but also exposed many of them Defects, if any, to increase equipment, increase costs, and some still exist security risks, however
