摘要
研究栽有黄瓜的Venlo型玻璃温室内外环境因子之间的相互影响。以栽有黄瓜的Venlo型两连栋玻璃温室为对象,利用温室控制系统自动记录、保存夏季温室内外温度、湿度、光照的数据。通过分析记录的环境数据,晴天时:室内外温度最大值相差幅度18.97%;相对湿度相差39.6%;阴天时:室内外温度最大值相差幅度15.68%;相对湿度相差35.9%。在晴天和阴天时室内外的光照的差值没有显著差异,这主要是由于覆盖材料决定光照的透射率。研究结果可以为栽有黄瓜的Venlo型玻璃温室环境优化调控提供理论基础和决策支持。
To study the interaction of environmental factors inside-outside Venlo-type glass greenhouse planted with cucumber,it was considered Venlo-type glass greenhouse planted with cucumber as the object.The greenhouse control system automatically was used to record and store the data of indoor and outdoor temperature,humidity and light.Through analyzing the records of environmental data,the results showed that the maximum temperature rate between indoor and outdoor was 18.97%and the relative humidity was 39.6% on sunny days while they reached 15.68% and 35.9%,respectively,on cloudy days.However,on the sunny and cloudy days,light between indoor and outdoor didn’t showed significant differences.It was mainly attributive to the cover material which decided the transmittance of light.The results could provided optimal control theory and decision support for planting cucumber in Venlo-type glass greenhouse environment.
