溫室大棚溫度怎么控制?種植效益有多高?

發布日期:2019-01-10 作者: 點擊:

    大棚溫度的調控是在良好保溫大棚的基礎上進行的保溫、加溫和降溫三個方面的調節控制,使溫度指標適應果樹各個生長發育時期的需要。溫室大棚广东快乐十分走势图內的溫度如何觀測?溫室大棚冬季怎樣提高溫度?大棚內如何增加溫度?怎么保持大棚中的溫度?

    為掌握種植大棚內的氣溫和地溫,應定儀器、定測量點、定時觀察記載。以溫室為例,白天接受大量太陽輻射能,熱量支出較少,則溫度上升較快且數值較高;夜間只有熱量的散失沒有收入,溫度不斷下降,溫度低。溫室在晴天的上午升溫快,午后降溫也快,夜間降溫慢。最低溫度一般出現在剛揭覆蓋物之后,8時30分左右,寒冷季節揭開草簾后氣溫略有下降,但很快回升,9~11時上升速度最快。在不放風的情況下,上午每小時上升5~8℃,12時之后氣溫仍在上升,但變得緩慢起來,13時達最高值。以后逐漸下降,15時后下降速度最快。覆蓋后,室內短時間內氣溫會回升1~2℃,而后非常緩慢下降,一夜間下降4?7℃。下降數值不僅取決于天氣條件,而且取決于管理技術措施和地溫狀況,保溫效果好的溫室下降幅度小,多云、陰天時下降1~3℃,晴天下降較多,遇到寒潮下降較多。

    大棚管广东快乐十分走势图內的熱源來自太陽光輻射,增加了光照強度就相應地增加了溫度,所以增加光照強度的措施都有利于提高溫度。


    1、揭蓋保溫覆蓋大棚:保溫覆蓋大棚揭得過早或蓋得過晚都會導致氣溫明顯下降。冬季蓋上覆蓋大棚后 ,短時間內溫度回升2~3℃,然后非常緩慢下降。若蓋后氣溫沒有回升,而是一直下降,說明蓋晚了。揭開大棚保溫被后,氣溫短時間內應下降1~2℃,然后回升。若揭開后氣溫不下降而是立即升高,說明揭晚了。揭開后薄膜上出現白霜,溫度很快下降,說明揭早了。揭開覆蓋大棚之前若室內溫度明顯高于臨界溫度,日出后可適當早揭。在極端寒冷和大風天氣,要適當早蓋晚揭。陰天適時揭開有利于利用散射光,同時氣溫也會回升,不揭時氣溫反而下降。生長期采用遮蓋保溫覆蓋大棚的方法進行降溫是不可取的,因為影響果樹光合作用。
