越冬黃瓜在結瓜初期易出現黃瓜生長的腐爛或壞死現象（特別是冬暖棚內靠近放風口下七、八棵黃瓜及壓膜線或壓膜竹竿下方黃瓜發病更重）
，即瓜農常說的“爛頭頂”病，輕者造成禿樁（無生長點），重zhong者zhe從cong蔓man頂ding向xiang下xia蔓man延yan造zao成cheng黃huang瓜gua莖jing蔓man腐fu爛lan死si棵ke，嚴yan重zhong影ying響xiang黃huang瓜gua產chan量liang，單dan獨du用yong藥yao防fang治zhi療liao效xiao不bu好hao，給gei菜cai農nong造zao成cheng較jiao大da損sun失shi。據ju筆bi者zhe觀guan察cha，越yue冬dong黃huang瓜gua“爛頭頂”病與植株鈣營養不良和棚內滴水及病菌感染有關。防治時應采取綜合措施更有效。

早期補鈣：黃huang瓜gua對dui鈣gai的de吸xi收shou強qiang度du最zui大da值zhi在zai結jie瓜gua前qian甩shuai蔓man期qi。黃huang瓜gua初chu瓜gua期qi幼you瓜gua對dui鈣gai的de吸xi收shou強qiang度du大da，對dui鈣gai的de需xu求qiu量liang增zeng加jia，而er使shi生sheng長chang點dian部bu位wei鈣gai供gong應ying不bu足zu表biao現xian缺que鈣gai症zheng狀zhuang。缺que鈣gai黃huang瓜gua整zheng株zhu矮ai化hua
