以“塞维斯”水果黄瓜为试材,采用大棚基质栽培方式,对3种不同结构的塑料大棚(对称型侧开窗大棚A、锯齿型顶侧开窗大棚B、不对称型顶侧开窗大棚C)和3种不同覆盖材料(PE膜、PO膜、SC膜)进行温光效应观测,并比较了不同处理对黄瓜生长的影响.通过对大棚结构的优化和覆盖材料的筛选,以期改善大棚的温光环境,为蔬菜作物提供较适宜的生长环境.结果 表明:1)3种不同结构大棚的散热性能B＞C＞A;棚内光照强度C＞A＞B;黄瓜产量B＞C＞A,B产量较A提高16.71％,C产量较A提高11.2％.2)3种不同覆盖材料大棚内温度差异主要来源于覆盖材料的透光性,SC膜和PO膜透光率高于PE膜;透光率直接影响黄瓜的产量,3种不同覆盖材...

’Severus’cucumber was used as experimental material and adopted soil-free cultivation in a tunnel.The temperature and light of plastic tunnels with 3 different types of plastic tunnels(symmetrical side window shed A,zigzag top side window shed B and asymmetric top side window shed C)and 3 different covering materials(PE film,PO film and SC film)were observated,and the effects of different treatments on cucumber growth were compared.The structure of the tunnels was optimized and the covering materials was screened to improve the tunnel′s phot...
