style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川增溫王哪種好,增溫" src="https://tyunfile.71360.com/WaterMark/UploadFile/Tkdzkj/637272286061621094/2357028.png"></div><p> 在農(nóng)業(yè)發(fā)展方面，在冬季蔬菜的產(chǎn)量受影響還是比較大，由于冬季氣溫較低，加之冰雪、霜凍等自然災害的頻繁發(fā)生，將對蔬菜大棚內的農(nóng)作物產(chǎn)生不利影響，因此在寒冷的冬季，如何增加蔬菜的產(chǎn)量，溫度方面是重要的因素，那么在建大棚時或者在日常維護中，有哪些方式可以為蔬菜大棚增溫呢？ </p> <p> 1、在建大棚時要選擇下沉式蔬菜大棚施工 </p> <p> 建造蔬菜溫室時。當蔬菜大棚內地面下沉半米以上至凍土以下時，種植的地上作物的土壤溫度將高于水平地面。同時，由于蔬菜大棚內地面下沉，大棚內空間會增加，利于保溫。 </p> <p> 2、在建設大棚時選擇透光性好的蔬菜大棚膜 </p> <p> 大棚建造時大多選用無滴膜，這種大棚膜具有良好的透光性和保溫性能。同時，應每周清洗薄膜表面，保持良好的透光性。青海紅皎陽增溫值得推薦凍害發(fā)生前增溫成活率****；凍害發(fā)生中出現(xiàn)萎焉現(xiàn)象，有死亡；凍害發(fā)生后增溫無意義。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川增溫王哪種好,增溫" src="https://tyunfile.71360.com/WaterMark/UploadFile/Tkdzkj/637272286077753907/4336134.png"></div><p> 1、輔助措施提溫 </p> <p> 在正常管理條件下，若還不能實現(xiàn)蔬菜生長的適宜溫度，可以通過采取一些簡單輔助措施進行增溫，用以抵御低溫或寒潮。 </p> <p> 一種是在鋼絲上加蓋二膜，也就是棚中棚，白天揭開薄膜，夜間閉合，能有效提高夜溫2-3℃。設置二膜時，前臉處也應加設一層。 </p> <p> 二是使用燃燒塊。燃燒塊產(chǎn)生熱量大，燃燒慢，一畝地使用6-8塊，可以在短時間內提高棚溫4-5℃，寒潮來臨當天零時、四時后點燃一次或兩次，就可以比較好的減少蔬菜冷害的發(fā)生。 </p> <p> 三是對于大型苗場來說，幼苗抗逆能力差，冬季棚室保溫是必備的，常用大型設備，如半導體電鍋爐、碳纖維加熱板、空調等，提前加熱，預防低溫危害。如使用數(shù)控鍋爐時，當育苗棚溫度低于16℃時，就應啟動數(shù)控鍋爐，一臺鍋爐加熱，利用熱水在棚內循環(huán)，然后利用風機將熱量均勻分散至棚內各個區(qū)域，確保增溫均勻。使用時，應提前設置好啟動和停止溫度，注意不要忽略余溫，避免棚溫過高，秧苗徒長。 </p><p> （1）提高棚內溫度 </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。因此，能使土壤保持疏松。 </p> <p> （4）加速土壤養(yǎng)分轉化，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 /> 大棚增溫塊任何作物都可用，無害，不傷人，不傷作物。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川增溫王哪種好,增溫" src="https://tyunfile.71360.com/WaterMark/UploadFile/Tkdzkj/637272286207343750/9748672.png"></div><p> 增溫措施當中經(jīng)濟的是利用陽光，其次是利用取暖設備增溫。雖然后者措施作用相對好，但由于成本高，很難被農(nóng)民接受。所以，把二者結合既降低了成本又達到了增溫的作用。 </p> <p> 1、確認正確的方向 </p> <p> 大棚要建在避風向陽的地方，其溫室方向以正南偏西，因為我們處在高緯度的北半球，冬季氣候寒冷溫較差大，早晨氣溫很低，過早揭苫后室內溫度會急聚下降，從而影響蔬菜的生長發(fā)育。所以，冬季溫室應適當晚揭苫。下午晚蓋苫大約在太陽落山前后，以增加光照時間，利用陽光的能量，達到增溫的目的。 </p> <p> 2、增加陽光入射率，增加光照強度 </p> <p> 增加陽光入射率要解決兩個問題：一是棚面薄膜的選擇，使用無滴膜，因為無滴膜能使棚面保持無水珠，增加陽光的入射率，增加了光照強度，從而增加溫室內的溫度。其二是設計合理的棚面角度和減少棚內立柱，棚內立越少越好，以無立柱鋼筋骨架，這樣陽光入射率能增加，溫度也會有所增加。 </p> <p> <br /> 大棚增溫塊棚內進行多層覆蓋。青海紅皎陽增溫值得推薦</p><p

澆水是導致棚室內濕度增加的主要因素。澆水的次數(shù)和每次的澆水量，需根據(jù)天氣、土壤狀況、蔬菜種類、生長期及生長勢而定，一般應澆小水或隔溝輪澆，切忌大水漫灌。 </p> <p> 2、加強中耕松土 </p> <p> <span style="display:none;"></span>在定植后、覆蓋地膜前，澆水后及時中耕松土，可減少蒸發(fā)，保持土壤水分，減少澆水次數(shù)，降低空氣濕度。 </p> <p> <span style="display:none;"></span>3、升溫降濕 </p> <p> 棚室內氣溫每升高1℃，空氣中的相對濕度下降3%～5％。采用升溫降濕方法既可滿足蔬菜對溫度的需要，又可降低空氣相對濕度。 </p> <p> 當植株度過幼苗期，抵抗力稍強時，澆水閉棚升溫達30℃左右，持續(xù)1小時，再通風排濕。3～4小時后棚溫低于25℃時可重復一次。 </p> <p> <br /> </p> <p> 4、改變 </p> <p> 菜農(nóng)用藥以噴霧為主，這勢必會增加棚內濕度。建議晴天噴藥時，在下午三點左右進行，盡量在天黑以前噴完，保證藥液完全吸收。 </p> <p> 遇連陰天，菜農(nóng)可以選用全自動噴藥機、彌霧機，并減少用藥量。 </p> <p> 5、減少無效蒸騰 </p> <p> 棚室蔬菜生產(chǎn)的中后期，植株蒸騰是室內水汽的主要來源，必須通過及時修整枝蔓、摘心打頂、除去枯老葉，以及拔去弱勢植株等農(nóng)藝措施，改善植株群體結構，從而降低植株無效蒸騰。 </p> <p> <br /> </p> <p> <span style="display:none;"></span> 四川增溫王哪種好</p><p>
