<p> 1、提早扣棚：選用耐低溫的塑料薄膜提早扣棚或扣棚越冬，可使棚內(nèi)土壤早化凍。2、開溝曬土：扣棚后，在準(zhǔn)備定植的地方，用鍬開20～30厘米寬的溝，化一層挖一層，挖到20～30厘米深，曬溝曬土；定植前溝施馬糞，并將土復(fù)原，以加速化凍，提高地溫。3、淺定植，澆埯水：定植時，使苗坨與地面平或略高于地面，防止栽得過深；栽后澆埯水，防止大水漫灌。4、開側(cè)溝：深松土定植后，在離苗坨5厘米處開溝曬土（在地溫較高時，可用此溝施肥），并在行間多次深摟松土，以利增溫保墑，促進(jìn)緩苗。5、多層覆蓋：據(jù)觀測，在塑料大棚內(nèi)套小拱棚，可使小拱棚內(nèi)的氣溫提高2℃～4℃，地溫提高l℃～2℃；在大棚中采用塑料薄膜做成二層幕，于夜間覆蓋，可使棚內(nèi)氣溫、地溫平均提高1℃～2℃；在大棚四周覆蓋一層1米高的草苫子，亦可使棚溫提高1℃～2℃。增溫器推薦有了大棚增溫塊冬季大棚增溫不費(fèi)力了。</p><div

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(dá)到-8℃，如何比較好的增加棚里的溫度，減少作物出現(xiàn)凍害減產(chǎn)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(shè)備 </p> <p> 育苗棚可以通過地鋪電熱絲的方式對幼苗進(jìn)行增溫；種植棚可以通過電熱風(fēng)扇、電鍋爐、燃燒甲醇、安裝浴霸增溫?zé)舻戎T多方式對大棚進(jìn)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(yù)報(bào)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(shè)備，實(shí)現(xiàn)草莓不受低溫凍害。 </p> <p> 棚體結(jié)構(gòu)完善 </p> <p> 棚外加設(shè)保溫被或者草氈，棚里加設(shè)二膜、三膜，對于不耐低溫的作物可以加設(shè)小拱膜。同時修繕棚膜，實(shí)現(xiàn)良好的密封性。 </p> <p> 鋪設(shè)地膜 </p> <p> 鋪設(shè)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 /> </p><p> 增溫措施當(dāng)中經(jīng)濟(jì)的是利用陽光，其次是利用取暖設(shè)備增溫。雖然后者措施作用相對好，但由于成本高，很難被農(nóng)民接受。所以，把二者結(jié)合既降低了成本又達(dá)到了增溫的作用。 </p> <p> 1、確認(rèn)正確的方向 </p> <p> 大棚要建在避風(fēng)向陽的地方，其溫室方向以正南偏西，因?yàn)槲覀兲幵诟呔暥鹊谋卑肭?，冬季氣候寒冷溫較差大，早晨氣溫很低，過早揭苫后室內(nèi)溫度會急聚下降，從而影響蔬菜的生長發(fā)育。所以，冬季溫室應(yīng)適當(dāng)晚揭苫。下午晚蓋苫大約在太陽落山前后，以增加光照時間，利用陽光的能量，達(dá)到增溫的目的。 </p> <p> 2、增加陽光入射率，增加光照強(qiáng)度 </p> <p> 增加陽光入射率要解決兩個問題：一是棚面薄膜的選擇，使用無滴膜，因?yàn)闊o滴膜能使棚面保持無水珠，增加陽光的入射率，增加了光照強(qiáng)度，從而增加溫室內(nèi)的溫度。其二是設(shè)計(jì)合理的棚面角度和減少棚內(nèi)立柱，棚內(nèi)立越少越好，以無立柱鋼筋骨架，這樣陽光入射率能增加，溫度也會有所增加。 </p> <p> <br /> 使用數(shù)控鍋爐時，當(dāng)育苗棚溫度低于16℃時，就應(yīng)啟動數(shù)控鍋爐，一臺鍋爐加熱，利用熱水在棚內(nèi)循環(huán)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

在農(nóng)業(yè)發(fā)展方面，在冬季蔬菜的產(chǎn)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(zāi)害的頻繁發(fā)生，將對蔬菜大棚內(nèi)的農(nóng)作物產(chǎn)生不利影響，因此在寒冷的冬季，如何增加蔬菜的產(chǎn)量，溫度方面是重要的因素，那么在建大棚時或者在日常維護(hù)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(dāng)蔬菜大棚內(nèi)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(nèi)地面下沉，大棚內(nèi)空間會增加，利于保溫。 </p> <p> 2、在建設(shè)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，這種大棚膜具有良好的透光性和保溫性能。同時，應(yīng)每周清洗薄膜表面，保持良好的透光性。大棚增溫塊，短時間內(nèi)增加大棚內(nèi)的溫度，增溫同時釋放二氧化碳?xì)夥?。四川大棚增溫王安裝方式</p><p style="text-indent:25px">大棚增溫塊棚內(nèi)進(jìn)行多層覆蓋。四川大棚增溫王安裝方式</p><p> 蔬菜大棚增溫措施： </p> <p> 1）建造暖棚：暖棚墻體應(yīng)采用保溫材料，后屋面保溫土層厚度宜為15cm左右。門上應(yīng)設(shè)擋風(fēng)墻，門兩側(cè)應(yīng)設(shè)雙層窗簾，棚膜應(yīng)搭接嚴(yán)密。后墻應(yīng)抹白灰、水泥或草泥，以防熱量散失。設(shè)施外設(shè)置防寒溝，防溫室內(nèi)外溫度交換。 </p> <p> 2）增施肥料：試驗(yàn)證明，增施肥料可使溫室地溫升高1℃，二氧化碳濃度升高。 </p> <p> 3）增加蔬菜大棚的透光率：增加透光率的措施都利于設(shè)施內(nèi)更多熱量的積累。 </p> <p> 4）采用多層覆蓋：減少熱損失，是經(jīng)濟(jì)的保溫方法。比如，在溫室外蓋上保溫被，在溫室內(nèi)架好中間棚，在中間棚上蓋上草簾。 </p> <p> 5）控制澆水次數(shù)和數(shù)量：澆水可以使地溫和溫室溫度下降。在冬季和早春，要少澆水和不要大量澆水或者隔行澆水，如果可以就采用滴灌。 </p> <p> 6）蔬菜大棚室內(nèi)供暖：當(dāng)溫度達(dá)不到作物生長所需溫度時，可以采取設(shè)置爐灶、使用暖氣等室內(nèi)供暖措施，但要注意有專人看守，以防火災(zāi)和高溫的發(fā)生而燒毀農(nóng)作物。四川大棚增溫王安裝方式</p><p>
