- 摘要:
- 借助中国农业大学首创的日光温室光环境模拟软件，模拟研究不同屋面倾角对日光温室室内光照环境的影响。结果表明：当日光温室跨度一定，均为8 m，屋面倾角从26°增加到32°时，前屋面的平均透光率绝对值增加了0.5%；日光温室在指定时间段内，温室地面、墙面和后屋面的平均辐射照度分别增加了0.3%、10.9%和946%；单位温室长度的温室地面、墙面和后屋面的累计光辐射能量分别增加了0.2%、10.9%和1 450%；单位温室长度的累计光辐射总能量增加了7.06 MJ，增加率为15.1%，直散光比例也有一定程度的增加。综合考虑，当温室跨度不变时，屋面倾角可以适当增大2°～4°，达到32°左右，有利于日光温室光照的累积和温室内作物的生长。
- Abstract:
- With the help of the sunlight greenhouse light environment simulation software initiated by China Agricultural University，the effects of different roof inclination angles on the indoor light environment of sunlight greenhouse were simulated and studied.The results showed that the absolute value of the average transmittance of the front roof increases by 0.5% when the span of the greenhouse was 8 m and the inclination angle of the roof increases from 26° to 32°，the average irradiance of the ground，wall and back roof of the greenhouse increases by 0.3%，10.9% and 946% respectively in a specified period of time，and the cumulative radiation energy of the greenhouse floor，wall and back roof per unit length of the greenhouse increases by 0.3%，10.9% and 946% respectively.The cumulative total energy of light radiation per unit length of greenhouse increased by 7.06 MJ，the increase rate was 15.1%，and the proportion of direct astigmatism also increased to a certain extent.Considering comprehensively，when the span of greenhouse was unchanged，the inclination angle of roof can be increased by 2°-4°,to 32°，which was conducive to the accumulation of sunlight and the growth of crops in greenhouse.
