本实验以研究宁夏二代日光温室栽培条件下光照强度日变化为目的，利用照度计对温室内部不同区域进行以年为周期下每日不同时区光照强度进行监测，通过连续监测统计出该型温室在宁夏地区的光照日变化规律，为宁夏设施蔬菜生产过程中出现的补光不足与能源浪费问题提出解决方法。
The purpose of this experiment is to study the daily change of light intensity under the cultivation condition of the second generation solar greenhouse in Ningxia. The light intensity of different areas in the greenhouse is monitored by the illuminometer in different time zones of the day under the annual cycle. Through continuous monitoring and statistics, the daily change rule of light intensity of this type of greenhouse in Ningxia is obtained, which is the supplement of light and this paper puts forward solutions to waste problems of energy in the production process of protected vegetables in Ningxia.
