1.點(diǎn)燃沼氣燈或沼氣紅外爐一般應(yīng)在凌晨6時(shí)—8時(shí)氣溫較低的時(shí)候進(jìn)行，這樣增溫增氣肥效果比較好。不提倡在中午氣溫較高時(shí)點(diǎn)燃沼氣增氣肥，而且溫室內(nèi)溫度超過20攝氏度時(shí)也不宜利用沼氣進(jìn)行增溫、增氣肥。 </p> <p> 2.用沼氣增溫增氣肥的時(shí)間不宜過長(zhǎng)，每天一般點(diǎn)燃2-3小時(shí)后，大棚內(nèi)的溫度就可以提高2-4攝氏度，能夠有效防止作物低溫凍害的發(fā)生，同時(shí)大棚中的二氧化碳濃度也能夠達(dá)到作物生產(chǎn)要求。如果長(zhǎng)時(shí)間點(diǎn)燃，會(huì)造成二氧化碳濃度持續(xù)上升，超過一定濃度后反而會(huì)影響作物的正常生長(zhǎng)，所以一般每天點(diǎn)燃3小時(shí)左右為宜。 </p><p> 冬季，我們要經(jīng)常打掃和擦洗棚膜，為什么呢？ </p> <p> 及時(shí)清洗干凈棚膜上面的灰塵、污物、積雪，是為了增加光照，提高棚溫。大棚里的光照和熱量，主要來源于太陽(yáng)的輻射，保持棚膜干凈就是為了能更好的接受太陽(yáng)輻射，如果棚面很臟，長(zhǎng)時(shí)間不清洗的話，會(huì)影響棚內(nèi)的光照條件。所以我們要經(jīng)常打掃、擦洗棚膜。夏季或者說氣溫比較高時(shí)，用水沖洗的方法比較好，對(duì)棚膜的傷害也輕。但如果是冬季，氣溫低，用水沖洗的話容易結(jié)冰，還會(huì)降低棚內(nèi)溫度。所以不能用水沖。也有人會(huì)采用綁小布條的方式擦拭棚膜。采用綁小布條的方式，利用風(fēng)力來回?cái)[動(dòng)布條擦拭棚膜，雖不費(fèi)工，但棚上面和下面總是有小布條擦不到的地方。也有的菜農(nóng)采用拖把擦拭棚膜，雖然擦得比較干凈，但費(fèi)工費(fèi)時(shí)。如今給大家介紹一種棚膜除塵方法：先準(zhǔn)備一根比棚寬稍長(zhǎng)一點(diǎn)的繩子，然后在其綁一些布條，綁的布條一定要把繩子表面覆蓋起來，這樣就形成了一根布條繩。然后一個(gè)人拿著繩子一頭站在棚下，另一個(gè)人拿著繩子的另一頭站在棚后坡上，兩個(gè)人把繩子拉緊，來回?cái)[動(dòng)，在棚膜上一片一片地擦拭，很快就能把棚膜擦得干干凈凈。推行“遲通風(fēng)、早蓋棚”保溫增溫的越冬大棚通風(fēng)排濕方式。</p><div

燃煤熱水鍋爐的燃料是煤，傳熱介質(zhì)是熱媒水。煤的燃燒熱值低，價(jià)格低。利用鍋爐供暖，可在溫室內(nèi)設(shè)置熱水管道，這與溫室的作物需求密切相關(guān)。管道布置越密集，溫度場(chǎng)越均勻，溫度波動(dòng)越小。相反，溫度場(chǎng)分布不均勻，溫度波動(dòng)較大。另外，由于溫室水的比熱容較大，受干擾較小，所以溫室內(nèi)的溫度波動(dòng)相對(duì)較小。 </p> <p> 2、熱風(fēng)爐 </p> <p> 溫室熱風(fēng)爐按燃料種類可分為煤爐、油爐和煤氣爐。由于熱風(fēng)爐是一種直接供暖方式，與熱水鍋爐相比，啟動(dòng)時(shí)加熱介質(zhì)的熱容沒有損失，因此熱風(fēng)爐的熱容可用于溫室室內(nèi)供暖。而且由于熱風(fēng)爐在啟動(dòng)過程中不需要先加熱介質(zhì)，溫室的加熱滯后較短，溫室的溫度較快。當(dāng)溫室室內(nèi)外溫差較小，或白天室外太陽(yáng)強(qiáng)度好時(shí)，可關(guān)閉和打開熱風(fēng)爐調(diào)節(jié)室內(nèi)溫度環(huán)境，增加了溫室供暖的靈活性。由于直接供暖，溫室內(nèi)溫度分布的均勻性稍差，溫度波動(dòng)也較大。大棚增溫塊白天將熱量以液態(tài)方式貯存，來降低高溫。夜間空自動(dòng)將所貯熱量釋放，提高室內(nèi)溫度。陜西增溫推薦廠家</p><p style="text-indent:25px">一塊燃料塊兒可以釋放3600以上大卡熱量，相當(dāng)于18000多焦耳，釋放二氧化碳?xì)夥蕿?50立方米均值1400ppm 。四川增溫器哪家好</p><p> 投放大棚增溫塊 </p> <p> 通過測(cè)試，質(zhì)量比較好的增溫塊可燃燒5-6個(gè)小時(shí)，增加棚里溫度2-4℃，同時(shí)燃燒產(chǎn)生的二氧化碳可以作為氣肥，補(bǔ)充早晨透風(fēng)換氣前的二氧化碳含量，較好的增加諸如草莓、西紅柿等作物的產(chǎn)量。 </p> <p> 投放熏劑 </p> <p> 投放熏劑，例如殺菌劑熏劑，產(chǎn)生的微塵可以一定程度減少熱量的散失，對(duì)冬季大棚保溫有一定的效果，但要注意，藥劑要晚上避光使用，早晨要及時(shí)通風(fēng)。 </p> <p> 科學(xué)放風(fēng) </p> <p> 以草莓為例，一般早上九點(diǎn)半左右進(jìn)行一次10-15分鐘的短時(shí)間換氣，然后關(guān)閉風(fēng)口，待棚內(nèi)溫度升到20℃往上，一般是中午12半左右再進(jìn)行1-2小時(shí)的長(zhǎng)時(shí)間風(fēng)口打開。這樣既實(shí)現(xiàn)換氣補(bǔ)充二氧化碳濃度，又可以實(shí)現(xiàn)草莓不被外界低溫閃苗。四川增溫器哪家好</p></p><br
