摘　　要：日光温室加温是改善冬季日光温室作物生长环境的主要措施之一。选择典型节能型日光温室,利用暖风机加温试验研究加温方式作用下温室内温度时间、空间变化及在极端天气条件下和不同外界温度条件下的加温效果,并进行经济投入分析。结果表明:电暖风机加温后温室内温度明显提高且温度分布较均匀,平均温度比对照温室温度高4.23℃,其中平均最低温度提升效果最明显;低温天气时,平均温度比对照温室温度高4.24℃;寡照天气时,平均温度比对照温室温度高4.48℃。暖风机在外界温度-12^-4℃时对温室进行加温效果最佳。通过对几种传统的温室加温方式经济投入的分析表明,电暖风机是一种投资小,耗能低,经济效益相对较高的加温方式。The greenhouse heating was one of the main methods to enhance the growth environment of crop in win- ter. The energy-saving solar greenhouse was selected. The temporal and spatial variations of temperature in the so- lar greenhouse and the heating effects under the extreme weather condition and different outdoor temperatures were discussed by a heating experiment with an electric warm-air machine. The economic investment was also analyzed. The results show that the temperature in the greenhouse rises significantly and is distributed uniformly in the whole greenhouse after the heating by the electric warm-air machine. The average temperature in the heating greenhouse is 4.23℃ higher than in the control greenhouse, and the average minimum temperature in the heating greenhouse increases significantly. The average temperate in the heating greenhouse is 4. 24℃ higher than in the control greenhouse under the low temperature weather condition, while it is 4. 48 ℃ higher under the spare sunlight weath- er condition. The heating effect by the electric warm-air machine for the greenhouse is best when the outdoor tem- perature is - 12 - - 4℃. The analysis of economic investment with the different heating methods suggests that the warm-air machine is an economic heating measure for its small investment, low energy consumption and high economic benefit.
