style="text-indent:25px">溫室大棚撒菜常見問題： 1.依據(jù)氣溫靈便撒水:依據(jù)氣候條件，掌握“大晴天適度多撒水，陰雨天少撒水或不撒水，雨雪天決不撒水”的標準。當氣侯由晴轉(zhuǎn)多云時，水流量應(yīng)慢慢降低，時間間隔盡可能增加；當它從陰涼的地方轉(zhuǎn)晴時，水流量由小增大，時間間隔由長減短。 2.撒水為宜。冬天大棚蔬菜種植撒水分配在中午上下，較好早上10點前，中午6點之后。這時棚溫較為高，撒水后不良反應(yīng)較少。防止早中晚撒水，以防凍裂蔬菜水果。河水要盡可能多用于撒水，由于河水溫度較高，能夠降低對蔬菜水果的生理學(xué)危害。湖北農(nóng)業(yè)大棚造價蔬菜大棚本身也都是采用一些機械生產(chǎn)的，能夠在短時間內(nèi)較大的提升生產(chǎn)效率。</p><div

style="text-indent:25px">溫室大棚撒菜常見問題：淺水不適合過大。低溫時，拱棚蔬菜水果蒸發(fā)遲緩，用水量相對降低。因此灑水流量要小，間距適度長一些。切勿滲灌，應(yīng)選用注水或噴撒，防止低溫高低溫導(dǎo)致蔬菜水果根漚。撒水后的前幾天，非常容易導(dǎo)致拱棚環(huán)境濕度提升，要留意有效自然通風(fēng)減溫，防止病癥。下午平均氣溫高的情況下自然通風(fēng)一般較為適合。把握溫室大棚農(nóng)作物種植技術(shù)性，提升蔬菜水果生產(chǎn)量和品質(zhì)，并不是難題。此外，還能夠進一步提高蔬菜水果的收益，提升農(nóng)戶的實際工資，可以說益處多多。</p><p style="text-indent:25px">蔬菜大棚在實際進行建設(shè)的過程當中，墻體是非常重要的，因為如果想要建設(shè)蔬菜大棚的話，墻體是支撐的一個重要部分，為了保障蔬菜大棚在實際建設(shè)過程當中的強度，在建設(shè)之前一定要注意咨詢一下專業(yè)單位。蔬菜大棚的墻體在較近一段時間建造的時候，可能多多少少都得由于某一些不注意的情況，出現(xiàn)一些墻體滾壓不結(jié)實，切面不平整的現(xiàn)象，因為蔬菜大棚墻體質(zhì)量的好壞將直接影響到整個蔬菜大棚的使用壽命，因此在實際使用的過程當中必須要認真對待。蔬菜大棚表面看起來是比較光滑的，不會和整個蔬菜大棚的薄膜摩擦。</p><div
