摘　　要：试验通过对阿拉尔地区普遍使用的塑料棚膜透光率的测定,分析比较了不同棚膜透光率及其在不同光照条件下的季节变化规律,旨在为日光温室冬季生产合理选择塑料棚膜提供参考依据。The transmittance and its variance of different plastic film was examined and analyzed in different condition in this research. The main results are as follows： the transmittance of PE12 film is the highest and the PVC film is the lowest of all. The transmittance of PE film is higher than EVA film in the earlier phase and is lower later. The transmittance of 4 plastic films is different in both sunshine and cloudy sky and is higher in sunshine than in cloudy sky.
