近段時間
，我國北方地區持續陰雨天氣
，大棚內的濕度大
，造成植株徒長
、根gen係xi差cha
，長chang勢shi弱ruo，而er連lian陰yin天tian轉zhuan晴qing後hou，棚peng內nei溫wen度du升sheng高gao，導dao致zhi蔬shu菜cai葉ye片pian蒸zheng發fa量liang驟zhou然ran增zeng加jia，而er根gen係xi吸xi收shou水shui分fen的de能neng力li不bu及ji蒸zheng發fa量liang的de需xu要yao

，蔬shu菜cai就jiu會hui出chu現xian急ji性xing萎wei蔫nian現xian象xiang，影ying響xiang其qi生sheng長chang。其實，急性萎蔫是一種生理性病害，隻要管理得當，連陰天轉晴後可以得到緩解。
