不同类型大棚光环境特征比较研究
A comparative study on environmental characteristics of different types of sheds light
摘要
Abstract
In order to explore the different kinds of sheds and sheds light environment under different levels of coverage using such four types of coverage: ordinary shed( Ⅰ ), huge shed( Ⅱ ), huge shed with single-layer insulation film covering( Ⅲ ) and double-layer insulation film of huge shed( Ⅳ ), and index have been measured, such as solar radiation in different sheds, its transmission, and its distribution. Test results indicated that: Be it sunny or cloudy days, the solar radiation in process Ⅰ is higher than that in process Ⅱ; the average solar radiation transmittance in ordinary process Ⅰ increased by 1.5％ than process Ⅱ daily; giant multi-coverage shed cover three processing Ⅱ, Ⅲ, Ⅳ of daily average solar radiation and solar radiation transmittance decreased gradually, the differences of three treatments on a sunny day for solar radiation were 5.2％ and 4.1％, 8％ and 6％ on a cloudy day, these data indicate that the effect of increasing the multi-coverage on a cloudy day for solar radiation is greater than that on a sunny day. With the increase in coverage, sol ar radiation tends to be distributed evenly in the shed, though on a cloudy day solar radiation is moro evenly distributed than on a sunny day.关键词
