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(shí)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，楚雄玻璃大棚報(bào)價(jià)。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，楚雄玻璃大棚報(bào)價(jià)，楚雄玻璃大棚報(bào)價(jià)，此時(shí)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。設(shè)施園藝蔬菜栽培中，采用多層覆蓋進(jìn)行保溫.楚雄玻璃大棚報(bào)價(jià)</p><div

大棚膜作用如下： </p> <p> 農(nóng)民朋友都知道溫室大棚膜具有： </p> <p> 1、能夠調(diào)節(jié)溫室大棚溫度作用，因?yàn)榇笈锬つ軌蜃璧K空氣流動處于基本完全封閉模式，能夠**減少熱量散失。 </p> <p> 2、溫室大棚里由于長時(shí)期使用化肥導(dǎo)致土地板結(jié)，然而大棚膜能夠?qū)⒋笈锢锏耐寥罍p少了雨水及灌溉水的浸蝕，促進(jìn)根系生長，使土壤孔隙率增加，容量減少，防止土壤板結(jié)，保持土壤疏松，通氣良好，有利于根系發(fā)育，鹽堿地返堿現(xiàn)象減弱； </p> <p> 3、大棚膜能夠改善土壤中含水分狀況，能增加耕層土壤含水量4%—5%，使上下水分分布均勻，提高空氣濕度，多雨的季節(jié)時(shí)又能防止土壤沖刷，防澇，降濕，從而促進(jìn)蔬菜瓜果生長； </p> <p> 4、增加土壤養(yǎng)分含量，大棚減少了雨水的沖刷、肥料的流失，保肥效果好。大棚中土溫高有利于微生物活動，加速有機(jī)質(zhì)的分解及轉(zhuǎn)化，一般可提高氮50%—120%，磷15%—30%，氧化鉀170%。楚雄玻璃大棚報(bào)價(jià)我國南北方氣候差異很大，故棚型要求也不相同。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="楚雄玻璃大棚報(bào)價(jià),大棚" src="http://tyunfile.71360.com/UpLoadFile/2019/12/20/16/637124547789498157_ynzd169_3624573.jpg"></div><p> 光照是蔬菜生長的重要條件之一，多數(shù)蔬菜均屬喜光作物。鋼架大棚光照調(diào)控，經(jīng)常遇到陰、雨、雪天氣，出于保溫的需要，膜上需覆蓋草苫等保溫材料，因此常造成棚室內(nèi)光照不足，光強(qiáng)分布不均，影響蔬菜的光合作用。下面給大家分享幾種方法 </p> <p> 1、選質(zhì)量棚膜 </p> <p> 不同塑料薄膜的透光率差別較大，質(zhì)量差的薄膜透光率低，且隨著薄膜的老化，透光率衰減快。因此，冬季保護(hù)地應(yīng)選用透光性好、防塵、抗老化、無滴、消霧的功能膜作為覆蓋材料，白天盡量避免多層覆蓋，即使在陰天的情況下，在每天中午也要揭開草苫等覆蓋物，給予一定時(shí)間的透光。 </p> <p> 2、清潔棚膜 </p> <p> 冬季風(fēng)沙較大，棚室塑料膜面易受污染，特別是覆蓋草苫的膜面更容易受到草、灰塵、泥土的污染，要經(jīng)常清洗、打掃薄膜，增加薄膜的清潔度，以增加透光率。 </p> <p> 3、增掛反光幕 </p> <p> 反光幕是一種鍍鋁聚酯膜，具較強(qiáng)的反光作用。生產(chǎn)上，將反光幕垂直張掛在日光溫室后立柱南側(cè)或后墻，通過反光幕的反光作用，來增強(qiáng)日光溫室內(nèi)部的光照強(qiáng)度，改善溫室內(nèi)弱光帶光照的分布，此外必須設(shè)法增加室內(nèi)光照，改善光照的分布。 </p><p> 聚乙烯(PE)棚膜質(zhì)地輕(比重約0.96克/立方厘米)，柔軟，易造型，透光性好，無害，適于做各種棚膜、地膜，是我國主要的農(nóng)膜品種。其缺點(diǎn)是;耐候性及保溫性差，不易粘接。如果生產(chǎn)大棚薄膜，必須加入耐老化劑、無滴劑、保溫劑等添加劑，才能適于生產(chǎn)的要求。主要產(chǎn)品有: </p> <p> ①普通PE棚膜(又稱pe吹塑農(nóng)膜)不添加耐老化等助劑直接用原料吹塑生產(chǎn)的白膜，大棚及中小棚應(yīng)用量很大，但只能種植一季作物，浪費(fèi)能源，增加用工，生產(chǎn)上逐漸被淘汰。 </p> <p> ②PE防老化膜(又稱長壽膜,耐老化膜)系在PE樹脂中加入耐老化助劑，經(jīng)吹塑成膜。使用期可達(dá)12~18個月，不僅使用期延長，成本降低、節(jié)能，而且使產(chǎn)量與產(chǎn)值大幅度增加，它是設(shè)施栽培中重點(diǎn)推廣的農(nóng)膜品種。 </p> <p> ③PE無滴防老化膜(又稱雙防膜,長壽流滴膜)同時(shí)具有流滴性、耐候性、透光性和保溫性好，防霧滴效果可保持2-4個月，耐老化壽命可達(dá)12-18個月，是性能較全，使用較廣的農(nóng)膜品種 </p> <p> ④PE保溫棚膜這種覆蓋材料能阻止紅外線向大氣中輻射，可提高大棚溫度1-2℃，在寒冷地區(qū)應(yīng)用效果較好。 </p> <p> ⑤PE多功能復(fù)合膜具有無滴、保溫、耐候、長壽等多種功能，有的有阻隔紫外線功能，使棚內(nèi)紫外線透過減少。有的能控制菌核病子囊盤和灰霉菌分孢子的形成。北方冬季嚴(yán)寒所以大棚的跨度應(yīng)大一些.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
