传统的温室大棚冬季覆盖物为草帘、棉帘。这些覆盖物的起放工作量大,劳动环境差。实践证明,使用电动卷帘机,不仅大大延长了光照时间,增加了光合作用,更重要的是节省劳动时间,减轻了劳动强度。据调查,日光温室在深冬生产过程中,每667米2温室人工控帘约需1.5小时,而卷帘机只需8分
Winter greenhouse cover traditional straw curtain, cotton curtain. These covers have a large lifting workload and a poor working environment. Practice has proved that the use of electric rolling machine, not only greatly extended the light time, increased photosynthesis, more importantly, save labor time and reduce labor intensity. According to the survey, solar greenhouse in the winter production process, every 667 m 2 greenhouse artificial curtain about 1.5 hours, while the shutter machine only 8 points
