智能(neng)(neng)農(nong)業(ye)(ye)大棚(peng):智能(neng)(neng)農(nong)業(ye)(ye)大棚(peng)塑料薄膜溫室,在我國引進溫室中所占比重大。一般(ban)單棟(dong)跨(kua)度(du)為(wei)6.4~8m,檐(yan)高3.0~4.0m,開(kai)間(jian)距為(wei)3.0~4.0m。其(qi)特點是固定于(yu)屋脊部的(de)天(tian)窗(chuang)(chuang)能(neng)(neng)實現半邊屋面(50%屋面)開(kai)啟通(tong)風(feng)換氣,也可以設側窗(chuang)(chuang),屋脊窗(chuang)(chuang)通(tong)風(feng),屋脊窗(chuang)(chuang)的(de)通(tong)風(feng)比在同(tong)跨(kua)度(du)下反(fan)而高于(yu)半屋面窗(chuang)(chuang)。就(jiu)總體而言,該溫室的(de)自然通(tong)風(feng)效果均較好。且(qie)采用(yong)雙層充氣膜覆蓋,構(gou)件比玻(bo)璃(li)溫室少,空(kong)間(jian)大,遮陽(yang)面少,根(gen)據不(bu)同(tong)地(di)區(qu)風(feng)力強(qiang)度(du)大小和積雪厚度(du)可選擇相應(ying)類型結構(gou)。
