摘　　要：采用麦套、夏直播、夏直播覆膜和起垄覆膜4种种植方式,研究了其对夏花生叶绿素含量、净光合速率、气孔导度、单株叶面积、荚果数、荚果重和产量等农艺和生理性状动态变化的影响。结果表明,起垄覆膜种植方式下的光合性能在整个生育期内处于较高的位置,夏直播覆膜在生育期前期光合性能较高,而后期下降较快,夏直播在生育期前期光合性能较低,但是后期下降较慢,麦套在整个生育期内光合性能均较低。不同种植方式下花生产量从高到低依次为起垄覆膜、夏直播覆膜、夏直播、麦套。光合性能的高低是产量形成的决定因素。This article studied the effects of 4 planting patterns of wheat intercropping, summer sowing, summer sowing overbite membrane and ridging overbite membrane on chlorophyll content, net photosynthetic rate, stomatal conductance, leaf area per plant, pod dry weight and pod yield in peanut.The results showed that the photosynthetic performance in ridging overbite membrane plant patterns was higher in the whole growth period, the photosynthetic performance in summer sowing o-verbite membrane was higher during earlier growth period but lower in later growth period, the pho-tosynthetic performance in summer sowing was lower during earlier growth period but decreased slo-wer in later growth period.The pod yield from high to low was ridging overbite membrane, summer sowing overbite membrane, summer sowing and wheat intercropping.Photosynthetic performance was the decisive factor of pod yield formation.
