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，楚雄多肉大棚建設(shè)，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(jìn)，抗風(fēng)雪能力強(qiáng)，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(biāo)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(hù)，下面是一些具體的維護(hù)知識：

（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，楚雄多肉大棚建設(shè)，因此，應(yīng)經(jīng)常檢查，楚雄多肉大棚建設(shè)，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(zhǔn)。 </p> <p> <br /> 大棚高跨比越大單位面積用塑料薄膜量也增加。楚雄多肉大棚建設(shè)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="楚雄多肉大棚建設(shè),大棚"

1.連陰天時也要盡量揭開保溫被，利用散射光使作物充分接受光照，為了保證棚內(nèi)溫度，拉保溫被時間應(yīng)比晴天晚0.5-1個小時，下午放棚時間要比晴天早0.5-1個小時； </p> <p> 2.及時清掃棚膜，提高棚膜透光率，可在棚面上設(shè)置布條，利用風(fēng)吹布條給棚膜除塵，方法簡單易行，并可將棚膜上的大部分灰塵清掃干凈，同時要選擇質(zhì)量棚膜，減少棚膜內(nèi)面的結(jié)露，減少對透光率的影響；3.大棚后墻懸掛反光幕，可有效增加棚內(nèi)光照，促進(jìn)光和積累，但是要注意反光幕的懸掛高度。有條件的菜農(nóng)也可通過在大棚內(nèi)安裝補(bǔ)光燈來增加光照。 </p> <p> 大棚內(nèi)溫度的高低直接影響蔬菜能否正常生長，特別是夜間溫度過低時，植株很容易出現(xiàn)冷害、凍害，嚴(yán)重的導(dǎo)致蔬菜死棵。 </p> <p> 1.建議菜農(nóng)在棚膜外加蓋兩層草簾，上下層草簾呈品字交錯排布，比較低下鋪一層舊薄膜，以保持草簾干燥；2.冬季地溫低，菜農(nóng)在定植蔬菜時應(yīng)起壟定植，增加地面的見光面積，儲蓄熱量，并鋪設(shè)白色地膜提溫； </p> <p> 3.做好大棚前臉的防凍工作，大棚前臉時棚內(nèi)**容易大生凍害的地方，菜農(nóng)可以單獨給大棚前臉“開小灶”——在前臉處再加一層1米高的薄膜或廢舊草簾，不僅可以保溫，還可以防止前臉滴水，減少病害的發(fā)生。保山多肉大棚建設(shè)溫室大棚具有一定環(huán)境調(diào)控設(shè)備.</p><div style="width:100%;text-align:

</p> <p> 在了解了溫室大棚的作用以及植物生長所需要的要點以后，我們應(yīng)該溫室我們當(dāng)?shù)氐膶嶋H情況選擇合適的溫室大棚樣式。溫室大棚的選擇一定要把握“有什么、要什么、選什么”的原則，既要根據(jù)生產(chǎn)地的氣候天件，又要依據(jù)種植的種類和生產(chǎn)目的，選擇相應(yīng)功能和結(jié)構(gòu)的溫室大棚，有時需要綜合考慮溫室大棚的整體功能，切忌盲目建設(shè)，造成浪費。例如，灌溉水源無法保證的條件下，露天栽培比溫室大棚好;在陰雨連綿的產(chǎn)地，首先主要考慮防雨功能，再結(jié)合其他需要做選擇;如果用于種植藤蔓性作物，那溫室大棚一定要具備一定高度，溫室大棚兩側(cè)邊緣定植位置棚膜到地面高度不宜低于1.8 m，并且應(yīng)考慮大棚的承重結(jié)構(gòu)和引蔓設(shè)施;如果大棚用于早春育苗，溫室大棚主要考慮保溫功能;在缺水地區(qū)，規(guī)?；N植的溫室大棚宜配套節(jié)水灌溉設(shè)備。 </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(hù)會破損，大棚膜破損后雖然有補(bǔ)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(fēng)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(fēng)力及外力的沖擊。我們可以借助繩子的助力來降低風(fēng)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(fēng)，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(jìn)行修補(bǔ)，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高跨比越大，建造成本提高.</p><div

在不良天氣下，提高蔬菜自身的抗逆能力也是應(yīng)對惡劣環(huán)境、減少病害發(fā)生的重要手段之一。冬季地溫低，根系活性差，再加上連陰雨雪天氣，管理不當(dāng)很容易對根系造成傷害，特別是澆水或施肥不當(dāng)造成的傷根更為普遍。一般復(fù)合肥是不適合冬季沖施的，復(fù)合肥溶化到水中會進(jìn)一步降低水溫，不僅導(dǎo)致地溫下降，還會損傷蔬菜根系，而且復(fù)合肥的養(yǎng)分利用率低，長期使用會導(dǎo)致土壤板結(jié)和鹽害。建議菜農(nóng)朋友在冬季選擇沖施肥時比較好選擇全水溶性肥料和養(yǎng)根的功能性肥料，如腐殖酸類、氨基酸類、海藻酸類、甲殼素類、核苷酸類等肥料，如果利多生根劑這一類肥料可刺激植物生根，提高植株的抗逆能力。雖然功能性肥料養(yǎng)根效果突出，但是由于其所含的氮、磷、鉀等營養(yǎng)元素含量很低，不能長期施用，一定要與全水溶性肥料搭配施用。根靠葉養(yǎng)，葉靠根生，冬季連陰雨雪天氣，棚內(nèi)溫度低，地溫也低，根系活性差，吸收養(yǎng)分的能力減弱，容易導(dǎo)致植株缺乏營養(yǎng)，生長不良，此時就應(yīng)通過葉面噴施來補(bǔ)充營養(yǎng)。建議菜農(nóng)在大雪來臨前，葉面噴施甲殼素、海藻酸以及光合動力等全營養(yǎng)葉面肥，補(bǔ)充葉片急需的中微量元素、有機(jī)營養(yǎng)等，既能緩解營養(yǎng)供應(yīng)不足的情況，又能提高葉片的抗寒抗病能力。溫室大棚的基礎(chǔ)是承載整個溫室結(jié)構(gòu)的.大理玻璃大棚設(shè)計</p><p style="text-indent:25px">南方地區(qū)溫度較高，此地溫帶不明顯，故大棚的跨度可小一些。楚雄多肉大棚建設(shè)</p><p> 久陰驟睛后的管理 </p> <p> 長時間的連陰天氣，好幾天揭不開草簾，特別是大雪過后，天氣突然轉(zhuǎn)晴，若菜農(nóng)急于將大棚草簾完全揭開，此時氣溫迅速上升，空氣濕度降低很快，葉片蒸騰加快，而地溫較低，根系活動弱，吸收能力很低，很容易造成葉片生理性水分失調(diào)，導(dǎo)致植株萎蔫甚至死亡。在天氣轉(zhuǎn)晴后，注意及時通風(fēng)，但通風(fēng)口不能開得太大，以防止溫度驟變對植株造成影響。2-3天后待植株逐漸適應(yīng)再轉(zhuǎn)入正常的揭蓋管理。揭開草簾后，若發(fā)現(xiàn)蔬菜出現(xiàn)萎蔫現(xiàn)象，應(yīng)立即蓋上草簾，等葉片恢復(fù)后再揭開，反復(fù)數(shù)次直到不再萎蔫。不使用卷簾機(jī)的菜農(nóng)可以放花簾，隔一個拉一個避免光照太強(qiáng)。發(fā)現(xiàn)苗子萎蔫，可在萎蔫的苗子上噴清水或1％的葡萄糖水，盡快恢復(fù)植株長勢。楚雄多肉大棚建設(shè)</p><p
