鋼架大棚是現(xiàn)在農(nóng)業(yè)發(fā)展中不可或缺的重要溫室大棚，溫室大棚一般全部采用全鋼架大棚結(jié)構(gòu)，結(jié)構(gòu)先進，抗風雪能力強，適宜國內(nèi)大部分地區(qū)使用。這種鋼架溫室大棚骨架全部使用國標熱鍍鋅鋼架加工而成，使用壽命更長。雖然鋼架大棚先天有很多優(yōu)點，但是離不開我們后期的維護，下面是一些具體的維護知識： </p> <p> 維護知識（一） </p> <p> 1、在搭建時要安裝牢固鋼架大棚 </p> <p> （1）棚腳入土到位棚腳邊緣的土壤，一般會因耕作逐年下降，使棚腳入土變淺，造成大棚傾斜。因此，大棚腳的入土深度一定要達到40厘米的標準。 </p> <p> （2）連接桿扎緊扎牢大棚的三道連接桿與骨架接觸部位用鐵絲扎緊扎牢，有的用竹竿做連接桿，但竹竿會因干燥收縮而松動，因此，應(yīng)經(jīng)常檢查，隨時扎緊并間隔2—3年更換一次，以防竹竿老化，大棚傾斜。 </p> <p> （3）大棚支撐牢固水泥大棚兩端的混凝土支撐桿，用兩長兩短，即兩根短撐桿與連接桿對準。 </p> <p> <br /> 保山餐廳大棚報價大棚的長寬比值對穩(wěn)定性有密切關(guān)系。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="臨滄餐廳大棚報價,大棚" src="http://tyunfile.71360.com/UpLoadFile/2019/12/20/16/637124547789654272_ynzd169_7950802.jpg"></div><p> 1、缺少雨季排澇系統(tǒng) </p> <p> 正確的方法是，棚前臉處挖一條東西走向與大棚同長的排水溝，排水溝寬約半米，深約30厘米左右。好讓大棚面上留下的水隨時流走，防止水流入棚內(nèi)。 </p> <p> 2、后兩排立柱間距太大 </p> <p> 溫室大棚內(nèi)后兩排立柱之間，間隔盡量縮小，應(yīng)在80厘米左右，中間只建一條東西走向的水泥溝兼人行路即可。 </p> <p> 3、兩棚之間空地太少 </p> <p> 首先，冬季前面大棚對后面遮陰太大，使大棚的前半部分蔬菜生長不利。其次，對排澇害處較大。會出現(xiàn)冬季下雪時，掃雪棚前堆不下的情況。所以兩棚之間空地的正確距離以4－5米為宜，這樣既不互相遮陰，又可防風。 </p> <p> 4、后坡缺少保護措施 </p> <p> 要在溫室大棚后坡包上一層塑料布，再在外面包上一層無紡布。每10米左右用鋼絲封一下，這樣可保證五年左右，沒有太大的問題。 </p><p> 大棚膜是農(nóng)業(yè)生產(chǎn)重要的生產(chǎn)工具，大棚膜由于比較薄，如果不好好保護會破損，大棚膜破損后雖然有補救方法，但也會對壽命造成損失。在日常的管理中如何防止破損呢？ </p> <p> 北方天氣風力較大，所以對大棚薄膜來說是不小的挑戰(zhàn)，如果出現(xiàn)破裂會直接影響到農(nóng)作物的生長狀況，甚至還有可能因為溫度的降低造成瓜果蔬菜的死亡，所以廣大農(nóng)民朋友們要做好防備，使大棚薄膜免受風力及外力的沖擊。我們可以借助繩子的助力來降低風力的危害，可以用繩子壓緊大棚薄膜；在中午溫度升高時也要及時的放風，降低棚內(nèi)的溫度；一旦發(fā)現(xiàn)大棚薄膜有破損的情況時要及時進行修補，大棚內(nèi)水泥柱以及竹竿等表面要光滑，這樣也能減少對大棚薄膜的摩擦，防止破損。大棚膜要防止大棚膜破損，要經(jīng)常檢查。防止自然對大棚膜的破壞，比如冰雹，暴雨。同時也要避免人為破壞，像不懂事的小孩戳破大棚膜等大棚蔬菜栽培，通常是多茬次形態(tài)栽培，所以，條件優(yōu)良的泥土和水利前提。</p><div

智能溫室貴在“智能控制系統(tǒng)”:智能溫室的“中樞系統(tǒng)”即智能溫室監(jiān)控系統(tǒng)。它由傳感器、自動化控制系統(tǒng)、通訊、計算機技術(shù)與**系統(tǒng)與一體，通過預(yù)裝多種作物生長所需的適宜環(huán)境參數(shù)，搭建溫室智能化軟硬平臺，實現(xiàn)對溫室中溫度、濕度、光照、二氧化碳、營養(yǎng)液等因子的自動監(jiān)測和控制。溫室大棚內(nèi)溫度、濕度、光照強弱以及土壤的溫度和含水量等因素，對溫室的作物生長起著關(guān)鍵性作用。 </p> <p> 溫室內(nèi)的空氣溫度、土壤溫度、相對濕度、CO2濃度、土壤水份、光照強度、水流量以及PH值、EC值等參數(shù)進行實時自動調(diào)節(jié)、檢測，創(chuàng)造植物生長的適合環(huán)境，使溫室內(nèi)的環(huán)境接近人工設(shè)想的理想值，以滿足溫室作物生長發(fā)育的需求。適用于種苗繁育、高產(chǎn)種植、名貴珍稀花卉培養(yǎng)等場地，以增加溫室產(chǎn)品產(chǎn)量，提高勞動生產(chǎn)率。是高科技成果為規(guī)?；a(chǎn)的現(xiàn)代農(nóng)業(yè)服務(wù)的成功范例。一般大棚的棚型越大，設(shè)施內(nèi)熱容量越大，散熱越慢，所以北方大棚的面積應(yīng)大于南方。臨滄餐廳大棚報價</p><p

大棚膜用于設(shè)施農(nóng)業(yè)生產(chǎn)建設(shè)的**塑料薄膜，其透光率，保溫，抗拉及耐老化方面的性能均優(yōu)于普通農(nóng)膜。對大棚農(nóng)作物的生長，增產(chǎn)及增收具有重要意義。我國常用的大棚膜主要有四種:第一種是乙烯-醋酸乙烯共聚物棚膜;第二種是聚乙烯(PE)棚膜;第三種是聚氯乙烯(PVC)棚膜;第四種是調(diào)光性農(nóng)膜。這幾種棚膜在性質(zhì)上有相同之處，也有不同之處，因而使用效果也有差異，后面會將各自優(yōu)缺點陳列，可適當參考： </p> <p> 1：乙烯-醋酸乙烯共聚物(簡稱EVA)棚膜:(添加一定比例的eva),EVA樹脂是近年來用于農(nóng)業(yè)上的新的農(nóng)膜材料，用其制造的農(nóng)膜，透光性、保溫性及耐候性都強于PVC或PE農(nóng)膜。EVA農(nóng)膜覆蓋可較其他棚膜增產(chǎn)10%左右，可連續(xù)使用2年以上，老化前不變形，用后可方便回收，不易造成土壤或環(huán)境污染。臨滄餐廳大棚報價</p><p
