【摘要】 [目的]为日光温室的科学管理提供理论依据。[方法]测定日光温室的光照、温度和湿度并作相关分析。[结果]温室内空气湿度、地面温度最大值都出现在14:00左右,最小值出现在6:00前后。秋季温室内外地面温度存在6.8℃温差。光照南侧比北侧高960 lx;中间比东、西侧的高2230 lx、1560 lx;上层比中层、下层分别高73、720 lx。夜间空气湿度在90%以上,午后在80%以上。[结论]温室内空气湿度、地面平均温度日变化曲线为单峰型曲线;地面温度水平分布呈现出中间高四周低规律;温室内光照度日变化曲线类型是倒"V"型,而空间分布为南强北弱,上强下弱的规律。温室内空气湿度比较高,尤其是在夜间空气湿度更高。更多还原

【Abstract】 [Objective] The purpose of study was to provide the theoretical basis for scientific management of sunlight greenhouse.[Method] The illumination,temperature and humidity in sunlight greenhouse were determined and their correlations were analyzed.[Result] The maximum value of air humidity and ground temperature in greenhouse appeared at about 14:00 and their minimum value appeared at about 6:00.The indoor and outdoor temperature in greenhouse in autumn had difference of 6.8 ℃.The sunlight in south of greenhouse was 960 lx higher than that in the north and that in the middle was 2 230 lx and 1 560 lx higher than that in the east and west,resp.The sunlight in upper layer was 73 and 720 lx higher than that in the middle and lower layers,resp.The air humidity in the nights was over 90 % and that after the noon was over 80 %.[Conclusion] The diurnal variation curves of air humidity and ground mean temperature were single peak curve.The level distribution of ground temperature showed a law of being higher in the middle and lower in the around.The diurnal variation curves of illumination in greenhouse was backward V type and the space distribution showed a law of being strong in the south and weak in the north,and strong in upper layer and weak in lower layer.The air humidity in greenhouse was higher,especially in nights.更多还原
