摘要
在单栋大棚和连栋塑料温室内进行黄瓜栽培试验,以研究设施内土壤温度、空气温湿度的变化情况。结果表明:4-6月份上中旬,连栋塑料温室的土壤和空气温度均高于单栋大棚,但随着栽培时间的延长,二者最低温度差值逐渐减小;6-7月份,单栋大棚的最高土壤温度明显高于连栋塑料温室;整个生长期,连栋塑料温室内的空气湿度明显低于单栋大棚;连栋塑料温室的温、湿度环境比较适宜植物生长。
The cultural experiments with cucumber were carried out in single-span and multi-span plastic greenhouses to study the changes of soil temperature and air temperature and humidity within both greenhouses.The results showed that from April to the first or second ten days of June a multi-span plastic greenhouse was higher than a single-span plastic greenhouse in soil temperature and air temperature.But with culture lasting,both greenhouses gradually decreased in their difference of the lowest temperature.From June to July a multi-span plastic greenhouse was obviously lower than a single -span plastic greenhouse in the highest soil temperature.In the whole growth period a multi-span plastic greenhouse was obviously lower than a single-span plastic greenhouse in air humidity.It was concluded that the temperature and humidity of a multi-span plastic greenhouse were more suitable for plant growth.
