在農業(yè)發(fā)展方面，在冬季蔬菜的產量受影響還是比較大，由于冬季氣溫較低，加之冰雪、霜凍等自然災害的頻繁發(fā)生，將對蔬菜大棚內的農作物產生不利影響，因此在寒冷的冬季，如何增加蔬菜的產量，溫度方面是重要的因素，陜西紅皎陽增溫器，那么在建大棚時或者在日常維護中，有哪些方式可以為蔬菜大棚增溫呢？ </p> <p> 1、在建大棚時要選擇下沉式蔬菜大棚施工 </p> <p> 建造蔬菜溫室時。當蔬菜大棚內地面下沉半米以上至凍土以下時，種植的地上作物的土壤溫度將高于水平地面。同時，由于蔬菜大棚內地面下沉，大棚內空間會增加，陜西紅皎陽增溫器，利于保溫。 </p> <p> 2、在建設大棚時選擇透光性好的蔬菜大棚膜 </p> <p> 大棚建造時大多選用無滴膜，陜西紅皎陽增溫器，這種大棚膜具有良好的透光性和保溫性能。同時，應每周清洗薄膜表面，保持良好的透光性。越冬大棚階段，光照弱、溫度低。溫濕管理要以增加和延長有效生長溫度為重點。陜西紅皎陽增溫器</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西紅皎陽增溫器,增溫" src="https://tyunfile.71360.com/WaterMark/UploadFile/Tkdzkj/637272286224785157/8923318.png"></div><p> 半地下大跨度冬暖大棚的優(yōu)點：（1）增加大棚內的地溫。在冬季，隨著土壤深度的增加，地溫逐漸增高，半地下式冬暖大棚栽培比普通平地冬暖大棚栽培地溫要高。實踐證明，50~120厘米深度的半地下式冬暖大棚，比平地栽培的地下10厘米地溫要高2~4攝氏度。（2）這種構造方式可以增加大棚里的空間。有利于高秧作物的生長，有利于立體栽培。（3）增加了大棚的保溫性。冬暖大棚地面低于大棚外地面50~120厘米，棚體周圍相對厚度增加，所以保溫性好，再加上大棚的空間大了，還有利于儲存白天的熱量，增加了大棚的保溫性。（4）有利于二氧化碳的儲存。大棚的空間增大，相對空氣中的二氧化碳就多，有利于作物的生長，達到增產的目的。（5）不破壞大棚外的土地。大棚墻體在建造過程中，需要大量的土，以前的方式都是在大棚后挖溝取土，這種方式一是不利于大棚保溫，二是浪費了土地。這種方式是從大棚內取土，減少了對大棚外土層的破壞，不過從大棚內取土時要注意，要先將大棚內表層的熟土放在大棚前，將25厘米以下的生土用在墻體上，要避免用生茬土種菜。大棚增溫安裝操作注意事項避免果蔬遭受凍害，收成有保障；作物提前采收，產量增幅；長反季節(jié)作物，效益更高。</p><div

針對溫室大棚低溫凍害防范效果不佳的情況，西安同凱電子科技有限責任公司專門研發(fā)了“紅皎陽大棚增溫王”。激光大棚增溫王，大棚溫度控制。蔬菜大棚生產在冬季的時候生產效益明顯，大棚草莓溫度，但是由于冬季氣溫較低、而且還有冰雪、霜凍等自然災害時常發(fā)生，會對蔬菜大棚內的作物造成不利的影響，大棚溫度，所以說在寒冷的冬季，如何有效的增溫、保溫以及補光成為保證蔬菜大棚生產質量的重要技術。激光大棚增溫王針對冬季大棚果蔬生產研發(fā)而成，其采用大棚溫度大棚溫度大棚溫度大棚溫度激光陶瓷加熱技術，通過運轉可以30米內迅速升溫，大棚增溫王的工作原理是一種有效熱分布均勻的加熱器。熱導性很好的金屬合金，確保熱面溫度均勻，消除了設備的熱點及冷點。具有長壽命、保溫性能好、機械性能強、耐腐蝕、抗磁場等優(yōu)點。 </p><p> 俗話說一九二九不出手、三九四九冰上走。處在二九的冬天我國大范圍的降雪而顯得格外寒冷，陜西中部夜晚比較低的溫度甚至達到-8℃，如何比較好的增加棚里的溫度，減少作物出現凍害減產甚至死亡就顯得格外重要。下面就把溫室大棚增溫策略分享給大家。 </p> <p> 安裝增溫設備 </p> <p> 育苗棚可以通過地鋪電熱絲的方式對幼苗進行增溫；種植棚可以通過電熱風扇、電鍋爐、燃燒甲醇、安裝浴霸增溫燈等諸多方式對大棚進行比較好的增溫。以草莓為例，夜晚草莓生長的比較適合溫度是5-8℃，在天氣預報比較低的氣溫在-8℃左右且棚里溫度低于2到3℃時就可通過溫控或者手動啟動加熱設備，實現草莓不受低溫凍害。 </p> <p> 棚體結構完善 </p> <p> 棚外加設保溫被或者草氈，棚里加設二膜、三膜，對于不耐低溫的作物可以加設小拱膜。同時修繕棚膜，實現良好的密封性。 </p> <p> 鋪設地膜 </p> <p> 鋪設地膜可以比較好的增加地溫，市面上常見的地膜有三種，分別是黑銀雙面上下膜、黑膜和透明地膜。其中透明地膜增加地溫比較快，但黑膜和上下膜兼具防草的作用，上下雙面膜還能反射光照，并可以減少蚜蟲、白粉虱的發(fā)生。 </p> <p> <br /> 大棚增溫塊原來的作用是燒烤炭，近年來被發(fā)現可用于農業(yè)蔬菜大棚的增溫，其用途及用量被數倍放大</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="陜西紅皎陽增溫器,增溫"

一種是在鋼絲上加蓋二膜，也就是棚中棚，白天揭開薄膜，夜間閉合，能有效提高夜溫2-3℃。設置二膜時，前臉處也應加設一層。 </p> <p> 二是使用燃燒塊。燃燒塊產生熱量大，燃燒慢，一畝地使用6-8塊，可以在短時間內提高棚溫4-5℃，寒潮來臨當天零時、四時后點燃一次或兩次，就可以比較好的減少蔬菜冷害的發(fā)生。 </p> <p> 三是對于大型苗場來說，幼苗抗逆能力差，冬季棚室保溫是必備的，常用大型設備，如半導體電鍋爐、碳纖維加熱板、空調等，提前加熱，預防低溫危害。如使用數控鍋爐時，當育苗棚溫度低于16℃時，就應啟動數控鍋爐，一臺鍋爐加熱，利用熱水在棚內循環(huán)，然后利用風機將熱量均勻分散至棚內各個區(qū)域，確保增溫均勻。使用時，應提前設置好啟動和停止溫度，注意不要忽略余溫，避免棚溫過高，秧苗徒長。在大棚四周立草苫、秸稈等，可使大棚四周的溫度提高2℃—3℃或更高，并且費用低，適合在農村推廣使用。云南大棚增溫器供應</p><p
