冬季蔬菜大棚裏的氣害（氨氣）和風害（穿堂風）兩大隱害就好比兩大 yinxingshashou，suirankanbujianmobuzhe，dantamendeweihaichengduquebukexiaoqu。tebieshizaishucaijinruyibaowenweizhudeguanlijieduanhou，zheliangdayinxingshashouchengleweihaishucaishengchandezhuxiong，rubuduitamenzhongshihejinxingyouxiaodeyufang，jiuhuiduishucaizaochengyanzhongweihai。

氣害的危害及預防。從某種程度上講，氣害比病害、蟲chong害hai更geng為wei可ke怕pa，因yin它ta常chang會hui在zai較jiao短duan時shi間jian內nei熏xun壞huai蔬shu菜cai，使shi蔬shu菜cai大da幅fu減jian產chan，品pin質zhi嚴yan重zhong下xia降jiang。氣qi害hai的de產chan生sheng除chu了le冬dong季ji氮dan肥fei和he禽qin糞fen用yong多duo了le，使shi棚peng內nei氨an氣qi積ji累lei過guo多duo以yi外wai

，還hai因yin大da棚peng蔬shu菜cai早zao在zai定ding植zhi前qian就jiu施shi用yong了le大da量liang的de雞ji糞fen，這zhe些xie雞ji糞fen平ping時shi就jiu會hui揮hui發fa出chu氨an氣qi，但dan由you於yu揮hui發fa量liang較jiao少shao

，因yin此ci不bu會hui產chan生sheng氣qi害hai。但dan隨sui著zhe天tian氣qi逐zhu漸jian變bian冷leng，大da棚peng密mi閉bi後hou，氨an氣qi揮hui發fa不bu出chu去qu，在zai棚peng內nei積ji累lei得de多duo了le，就jiu對dui蔬shu菜cai造zao成cheng了le危wei害hai。尤you其qi是shi在zai衝chong施shi生sheng物wu菌jun肥fei後hou，雞ji糞fen腐fu熟shu速su度du突tu然ran加jia快kuai了le。這zhe時shi，即ji使shi冬dong季ji不bu大da量liang施shi用yong氮dan肥fei和he禽qin肥fei，隻zhi要yao前qian期qi大da量liang施shi用yong了le
