西藏林芝市巴宜区不同温室透光率对比研究

Comparison of Light Transmittance of Different Greenhouses in Bayi District,Linzhi City,Tibet

为全面了解西藏地区各类温室的透光率,探究设施内部光照强度的变化规律,研究不同时间段、不同设施透光率的日变化,以玻璃温室、日光温室、连栋大棚、单体大棚、干旱棚5种主要设施类型进行透光率对比,结果表明,玻璃温室、连栋塑料大棚的透光率稍低较高,日平均值分别为50.13%~57.92%、48.52%~54.11%,5种温室在室内光照分布均匀性上存在明显差异,这与温室骨架结构、骨架数量、分布及温室屋面倾斜角的大小等有关。

In order to comprehensively know the light transmittance of various greenhouses in Tibet,the study explores the variation law of light intensity inside the facilities,and studies the daily variation of light transmittance of different facilities in different time.The study compares the light transmittance of five main facility types:glass greenhouse,solar greenhouse,multiplex greenhouse,single greenhouse and drought shed.The results show that the light transmittance of glass greenhouses and multi-storey plastic greenhouses is slightly lower and higher,and the average daily values are 50.13%~57.92%and 48.52%~54.11%,respectively.There are obvious differences in the uniformity of indoor light distribution among the five greenhouses.This is related with the skeleton structure,framework number,distribution,and number of skeletons,etc.
