摘　　要：为了解黑龙江地区一种新型温室的内部光照强度及其空间分布特点,采用对比分析法,对冬季温室内东西向不同区域、南北向不同位置和垂直不同高度的光照强度进行了研究。结果表明,上午温室内光照西部强于东部,中午东、中、西部光照强度接近,下午东部光照强于西部;光照从温室南部向北部逐渐减弱,50 cm高度南北光照变化比较平稳;在0~200 cm高度,温室南部高处光照强于低处,温室北部低处光照强于高处,整体上表现为100~150 cm高度区域光照强于其他高度区域。地表光强始终低于其他高度。温室内部光照均匀度表现为11:30和14:30较高、10:30和13:30较低的特点。温室设计时建议缩短防寒被收起时宽度,东西山墙及后墙使用反光保温材料;在温室使用时建议卷起全部二层膜,从而增加温室内光照强度。In order to explore the internal light intensity and spatial distribution of a new type of greenhouse in Heilongjiang Province in winter,a comparative analysis method was used to analyze the light intensity of different locations,including east,west,north,south and heights.This study was intended to provide a reference for the greenhouse crops production in winter.The results showed that the light in the west of the greenhouse in the morning was stronger than that in the east.The light intensity in the noon was similar among the east,middle and west.The light intensity in the afternoon was contrary to the morning.From the south to the north of the greenhouse,the light intensity was gradually going down,but there was a little change of the light at 50 cm above the ground.At 0-200 cm above the ground,the light in the south of the greenhouse at higher height was stronger than that at lower height,but the light in the north was opposite.The light at heights of 100-150 cm was stronger than other heights.The light intensity of ground was always lower than others.At 11:30 and 14:30,the illumination uniformity was higher than that at 10:30 and 13:30.It is recommended to shorten the width of the cold proof quilt when designing the greenhouse,and use reflective insulation materials for the east and west gable walls and back walls;It is recommended to roll up all the two-layer films to increase the light intensity in the greenhouse.
