1.加jia強qiang通tong風feng
，降jiang低di棚peng溫wen。菜cai農nong在zai種zhong植zhi越yue夏xia蔬shu菜cai時shi
，為wei了le避bi免mian棚peng內nei蔬shu菜cai出chu現xian高gao溫wen障zhang礙ai，要yao注zhu意yi將jiang大da棚peng的de上shang下xia放fang風feng口kou全quan部bu打da開kai
，讓rang棚peng外wai的de冷leng空kong氣qi進jin入ru棚peng內nei後hou

，與yu棚peng內nei的de熱re空kong氣qi形xing成cheng對dui流liu
，以yi加jia速su熱re空kong氣qi的de排pai出chu，從cong而er有you利li於yu棚peng內nei溫wen度du的de降jiang低di。需xu要yao提ti醒xing菜cai農nong注zhu意yi的de是shi，在zai放fang風feng時shi
，要yao在zai放fang風feng口kou的de下xia方fang設she置zhi擋dang風feng膜mo，以yi防fang冷leng風feng直zhi吹chui到dao蔬shu菜cai的de果guo麵mian上shang
，導dao致zhi果guo實shi出chu現xian皴cun皮pi
、裂口等。

        2.使shi用yong遮zhe陽yang網wang降jiang溫wen。當dang通tong過guo放fang風feng方fang法fa還hai不bu能neng將jiang棚peng內nei溫wen度du控kong製zhi在zai適shi宜yi蔬shu菜cai生sheng長chang的de要yao求qiu範fan圍wei之zhi內nei時shi，菜cai農nong最zui好hao使shi用yong遮zhe陽yang網wang遮zhe陽yang降jiang溫wen。菜cai農nong應ying在zai上shang午wu棚peng內nei溫wen度du接jie近jin適shi宜yi蔬shu菜cai生sheng長chang的de最zui高gao溫wen度du時shi將jiang遮zhe陽yang網wang放fang下xia
，在zai下xia午wu棚peng內nei溫wen度du低di於yu適shi宜yi蔬shu菜cai生sheng長chang的de最zui高gao溫wen度du時shi將jiang遮zhe陽yang網wang卷juan起qi即ji可ke，但dan是shi要yao注zhu意yi在zai將jiang遮zhe陽yang網wang放fang下xia時shi不bu能neng擋dang住zhu放fang風feng口kou。在zai選xuan購gou遮zhe陽yang網wang時shi，菜cai農nong可ke以yi選xuan購gou遮zhe光guang率lv在zai60%左右的，因為這種遮陽網即能起到遮光降溫
，預防日灼果的作用，又能讓部分光線照射到大棚內部，有利於蔬菜葉片光合作用的提高。

        4.菜農還可像棚內蔬菜葉片上噴灑甲殼素、氨基酸、海藻酸等葉麵肥的方法
，促進蔬菜健壯生長
，提高其對高溫的抗逆性。
