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(shí)，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(shí)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(shí)，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(fèi)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(diǎn)。 </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(jìn)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，青海增溫器廠家，青海增溫器廠家，青海增溫器廠家。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(bǔ)充二氧化碳。 </p> <p> <br /> 任何含碳物質(zhì)不充分燃燒都會產(chǎn)生一氧化碳，在燃燒大棚增溫塊時(shí)一定進(jìn)行通風(fēng)處理。青海增溫器廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="青海增溫器廠家,增溫"

半地下大跨度冬暖大棚的優(yōu)點(diǎn)：（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(shí)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(dá)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(fèi)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。云南增溫器工作原理大棚增溫塊，方便快捷，增溫迅速，只需一根火柴輕松點(diǎn)燃，無需人工、設(shè)備投入。</p><div

在農(nóng)業(yè)行業(yè)中，溫室大棚發(fā)展規(guī)模越來越大，但是農(nóng)戶在冬季都會面臨由于溫度低造成的產(chǎn)量低，植物生產(chǎn)不茂盛等問題，那么要進(jìn)行大棚加溫來增加農(nóng)作物生長的問題。目前，溫室的增溫方式主要有熱水采暖、蒸汽采暖、熱風(fēng)采暖、電采暖和空調(diào)采暖。在實(shí)際應(yīng)用中，應(yīng)根據(jù)當(dāng)?shù)販厥医ㄔO(shè)的氣候特點(diǎn)、溫室熱負(fù)荷、當(dāng)?shù)厝剂瞎?yīng)和投資管理水平進(jìn)行選擇。1、熱水供暖熱水供熱系統(tǒng)由鍋爐、熱水輸送管道、水泵、散熱器、不同控制調(diào)節(jié)閥等組成。與熱風(fēng)、蒸汽采暖相比，該系統(tǒng)投資大，循環(huán)功率大，但熱損失小，運(yùn)行經(jīng)濟(jì)。一般情況下，冬季室外溫度在比較低，常采用熱水供暖系統(tǒng)，大棚加溫時(shí)間在3個(gè)月以上時(shí)，就會有好的作用。熱水供暖在我國北方應(yīng)用比較廣。2、蒸汽加熱以蒸汽為加熱介質(zhì)的供熱系統(tǒng)的組成與熱水供熱系統(tǒng)相似。但是，由于加熱介質(zhì)的溫度一般在100~110℃之間，因此用于熱介質(zhì)輸送的管道和散熱器要耐高壓、抗高溫、耐腐蝕、密封性好。3、熱風(fēng)加熱通過熱交換器將空氣直接加熱到溫室以增加室溫的方法。這種加熱方式強(qiáng)制加熱空氣，加熱的熱效率高。</p><p> 3、電熱溫室 </p> <p> 與其他能源形式相比，電能需要進(jìn)行熱電二次能源轉(zhuǎn)換，具有高的能源等級和較高的價(jià)格。在熱電轉(zhuǎn)換中，火電發(fā)電效率*為30%左右。因此，雖然電加熱的電熱轉(zhuǎn)換效率較高，但從整體能源利用情況來看，電加熱的能源利用效率很低。在種植蔬菜、水果的溫室內(nèi)使用電加熱既不經(jīng)濟(jì)又不合理。而對于苗木溫室來說，土壤溫度是溫室環(huán)境控制的主要目標(biāo)，它關(guān)系到發(fā)芽率和苗木的正常生長。實(shí)踐證明，采用電加熱法對局部土壤進(jìn)行加熱是可行的。 </p> <p> 4、電熱泵溫室 </p> <p> 所謂熱泵是將熱量從低溫區(qū)轉(zhuǎn)移到高溫區(qū)的設(shè)備的總稱。熱泵的熱原理與制冷機(jī)基本相同，但其用途和功能恰恰相反。電熱泵溫室是以電為動力，將相對低溫環(huán)境的熱量傳遞到相對高溫溫室的一種設(shè)備。白天，環(huán)境溫度高，部分太陽能轉(zhuǎn)化為熱量，對溫室起到加熱作用，使煤耗較其他時(shí)候有所下降。因此，溫室所需的大部分熱量在夜間供應(yīng)。大棚增溫塊白天將熱量以液態(tài)方式貯存，來降低高溫。夜間空自動將所貯熱量釋放，提高室內(nèi)溫度。</p><div

1、對大棚進(jìn)行熱空氣加熱。保護(hù)區(qū)內(nèi)的空氣由熱風(fēng)機(jī)直接加熱，熱風(fēng)溫度一般在60-80℃左右。它具有加熱速度快、控溫方便、加熱面積大的優(yōu)點(diǎn)，適用于多跨溫室或大型保護(hù)區(qū)。這個(gè)裝置簡單易移動。 </p> <p> 2、對大棚進(jìn)行電加熱。電加熱是一種方便的加熱方式。根據(jù)加熱面積，可相應(yīng)使用電加熱線、電加熱管、電加熱板、電加熱爐或加熱器、紅外加熱器等。電加熱法是多應(yīng)用于育苗。把電阻熱線埋在苗床下，溫度由繼電器自動控制。該方法供熱均勻，操作簡單，適用于工廠化育苗。加熱方便、快捷、易于控制。 </p> <p> 3、對大棚進(jìn)行發(fā)酵性加熱。將農(nóng)作物秸稈、肥料或餅肥等生物按適宜比例混合堆放發(fā)酵，發(fā)酵產(chǎn)生熱以保護(hù)地溫。該方法適用于增加地溫，原料豐富，成本低廉，還可增加室內(nèi)二氧化碳濃度。 </p> <p> 這些供暖措施各有特點(diǎn)和優(yōu)點(diǎn)，我們可以根據(jù)自己的需求進(jìn)行制定不同的大棚增溫的方案。增溫效果超過日光溫室大棚，省去二層膜和草簾成本，增加光照。冬季降低人工成本，免除人工費(fèi)用和其他費(fèi)用。廣東增溫器</p><p

一般來說，每加蓋一層防雨膜可以讓棚溫提高1-2度（不要加很多層，一般一層就行）。防雨膜一般固定在棚的底部，放下棉被，把膜拉上去蓋好，第二天把膜拉下來，把棉被升上去。這種方法是有經(jīng)驗(yàn)的農(nóng)民，嘗試了很多種不同的固定方法后，總結(jié)出來比較好用的一種。 </p> <p> 棉被覆蓋物 </p> <p> 接下來，咱們說說大棚上常用到的棉被。 </p> <p> 棉被的種類有很多，針刺氈保溫被、復(fù)合型保溫被、腈綸棉保溫被、棉氈保溫被、泡沫保溫被、防火保溫被、混凝土保溫被、大棚保溫被等。 </p> <p> 像咱們經(jīng)常用的就是一些舊碎布，然后經(jīng)過一定的處理后，重新壓制而成的那種針刺氈，也就是大家常說的黑心棉。這種棉被造價(jià)低，保溫性能好。又因?yàn)樽陨淼闹亓勘容^重，防風(fēng)性能也不錯(cuò)。青海增溫器廠家</p></p><br /><p>文章來源地址:
