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，溫度場越均勻，溫度波動越小。相反，溫度場分布不均勻，溫度波動較大。另外，由于溫室水的比熱容較大，受干擾較小，所以溫室內(nèi)的溫度波動相對較小。 </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，啟動時加熱介質(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，或白天室外太陽強度好時，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，大棚增溫器。由于直接供暖，大棚增溫器，溫室內(nèi)溫度分布的均勻性稍差，溫度波動也較**棚增溫器。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氣肥。大棚增溫器</p><div

半地下大跨度冬暖大棚的優(yōu)點：（1）增加大棚內(nèi)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(gòu)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(chǎn)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(nèi)取土，減少了對大棚外土層的破壞，不過從大棚內(nèi)取土?xí)r要注意，要先將大棚內(nèi)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。大棚增溫推薦廠家在大棚四周立草苫、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(nóng)村推廣使用。</p><div

在冬季，隨著外界溫度的下降，溫室內(nèi)的溫度也逐漸下降，當(dāng)土壤溫度較低時，會造成作物根系生長受阻，吸收能力差，植株抗逆境能力差。因此，溫室日常管理要做好保溫工作，有時還要采取大棚增溫的措施，讓農(nóng)作物健康生長。大棚增溫措施： </p> <p> 一、多層覆蓋 </p> <p> 室外溫度較低時，可采用多層覆蓋保溫。溫室一般由三層覆蓋，其中一些需要覆蓋在地面上。晚上，棚子上蓋著草簾，保溫作用好，但操作起來比較費力。 </p> <p> 地面覆蓋可以增加土壤溫度，降低棚內(nèi)濕度。本發(fā)明的邊溝覆膜秸稈法具有成本低、作用好的優(yōu)點。 </p> <p> 二、增加墻厚保溫層 </p> <p> 用這種方法，墻的熱量就向外分散就慢了。能增加溫室夜間溫度，在嚴(yán)寒期穩(wěn)定夜間溫度作用好。 </p> <p> 三、利用秸稈生物反應(yīng)器增加溫度 </p> <p> 根據(jù)種植邊界的大小，挖一條溝渠，用稻草填充，并放置微生物制劑。在稻草上覆蓋土，進行澆水，直到稻草可以倒出。 </p> <p> 秸稈在微生物的作用下逐漸分解，釋放熱量和二氧化碳。該措施可使根層土壤溫度增加，使土壤物理結(jié)構(gòu)和環(huán)境變好，為農(nóng)作物補充二氧化碳。 </p> <p> <br /> </p><p> 蔬菜大棚增溫措施： </p> <p> 1、利用取暖設(shè)備補充太陽光的不足 </p> <p> <span style="display:none;"></span>在寒冷的冬季，蔬菜的生長季節(jié)，靠日光只能達到白天的溫度需要，而夜間就不能達到作物對溫度的需要，這就要利用一些取暖設(shè)備來增加溫室內(nèi)的溫度。 </p> <p> 2、擋風(fēng)增溫 </p> <p> 在溫室的迎風(fēng)面夾擋風(fēng)障，在溫室后墻北面，正墻西面修建迎風(fēng)墻或用秫秸夾迎風(fēng)障子，從而可以減少溫室棚面風(fēng)速，減弱散熱強度，對溫室起到了增溫作用。 </p> <p> 3、利用發(fā)熱生物肥增加溫室內(nèi)地溫主要是利用馬糞發(fā)熱特性，將馬糞鋪在畦面上來達到增加地溫的目的。建議在日常管理中，加強檢查大棚漏風(fēng)區(qū)域，合理保溫。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="大棚增溫器,增溫" src="https://tyunfile.71360.com/WaterMark/UploadFile/Tkdzkj/637272285900712891/1491113.png"></div><p> 蔬菜大棚生產(chǎn)在冬季的時候生產(chǎn)效益明顯，但是由于冬季氣溫較低、而且還有冰雪、霜凍等自然災(zāi)害時常發(fā)生，會對蔬菜大棚內(nèi)的作物造成不利的影響，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(chǎn)質(zhì)量有效的重要技術(shù)。 </p> <p> 1、建設(shè)地面下沉式的蔬菜大棚 </p> <p> 建設(shè)蔬菜大棚時。將蔬菜大棚內(nèi)部的地面向下下沉半米以上，降到凍土層以下，相對水平地面下沉的地面作物生長的土壤溫度會更高，同時由于蔬菜大棚內(nèi)地面下沉，溫室大棚內(nèi)部空間加大，有利于保溫。現(xiàn)在，在我國冬暖式日光溫室發(fā)源地—山東壽光普遍采用這種結(jié)構(gòu)。 </p> <p> 2、選用透光性能好的蔬菜大棚膜 </p> <p> 生產(chǎn)上應(yīng)用多的是0.10-0.12mm聚氯乙烯長壽無滴膜，其透光保溫性能較好。同時，每周對薄膜表面進行清理，以保持良好的透光性能。 </p> <p> <br /> 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。大棚增溫推薦廠家</p><p style="text-indent:25px">利用太陽能源，無任何費用，安全性高，無污染的綠色、環(huán)保增溫新方式。大棚增溫器</p><p> （1）提高棚內(nèi)溫度 </p> <p> 土壤水分的蒸發(fā)是地溫散失的主要原因，由于薄膜的透光性好，能有效地使太陽光轉(zhuǎn)變成熱能。其次，薄膜透氣性差，減少了水分的蒸發(fā)，因而起到保溫增溫的作用。 </p> <p> （2）保持土壤水分 </p> <p> 由于地溫提高及熱效能的作用，土壤中的水分會沿著毛細管上移，經(jīng)薄膜阻擋并在膜面上聚成水滴而滴回土壤，讓水分呈上下運動狀態(tài)，使土壤均勻濕潤，從而有利于蔬菜生長。 </p> <p> （3）保持土壤疏松狀態(tài) </p> <p> 建棚后，避免了雨水沖刷帶來的土壤板結(jié)。因此，能使土壤保持疏松。 </p> <p> （4）加速土壤養(yǎng)分轉(zhuǎn)化，提高土壤養(yǎng)分利用率 </p> <p> 由于土溫的提高，土壤中的微生物數(shù)量增加，活性增強，加快了土壤有機質(zhì)的分解和銨態(tài)氮的消化，增加了土壤中的養(yǎng)分，也提高了土壤中二氧化碳濃度。同時，防止了土壤養(yǎng)分的流失。因此，提高了土壤養(yǎng)分利用率。 </p> <p> <br />
