一、大棚前期加温生产大棚生产的热源为太阳能,棚内温度与外界气温有直接关系。高寒地区,春季气温变化大,棚内蔬菜生长受抑制,甚至有受冻的危硷,所以增设加温设备,如用热风炉补充和调节大棚内温度,尤其是在夜间和阴暗严寒的白天提高棚温,并可以调节空气湿度和二氧化炭含量,人为控制棚内温度,保证作物的正常生长。根据当地条件可采取不同形式的加温方法。海拉
First, the production of greenhouses heating greenhouse production of solar energy for the first time, shed temperature and the outside temperature has a direct relationship. Alpine areas, the temperature changes in spring large shed vegetable growth inhibition, and even the risk of freezing of the alkali, so additional heating equipment, such as hot stove to supplement and adjust the temperature inside the greenhouse, especially in the dark and gloomy during the day and night Shed temperature, and can regulate air humidity and carbon dioxide content, artificially control the shed temperature to ensure the normal growth of crops. According to local conditions can take different forms of heating method. Hella
