In order to explore the best farming methods to prevent and control peanut waterlogging,the susceptible cultivar Zhonghua4 and the tolerant cultivar Xianghua2008 were selected respectively.Under different ridge heights(0,10,20 cm)and mulching methods,the leaf chlorophyll content,photosynthetic characteristics,pod yield and quality traits were measured.The results showed:①Under the conditions of waterlogging,with the increase of ridge height,the photosynthetic indexes such as net photosynthesis rate,stomatal conductance,intercellular carbon dio...
