玉米花生间作对玉米光合特性及产量形成的影响研究

摘要

在探索玉米花生间作中玉米光合特性及产量的过程中，对间作玉米进行研究。研究表明：间作能够将玉米功能叶片内的叶绿素含量提升，转变叶绿素的构造，明显提升了净光合速率。间作令玉米提升了光补偿点、光饱和点、光饱和中最大净光合速率、表观量子效率以及羧化效率，令CO2补偿点显著下降。间作显著提升了玉米生育后期单株干物质，加快籽粒成长，显著提升玉米产量，当量高出其所占面积比时，体现出显著的间作产量特点。%In exploring corn peanut intercropping maize photosynthetic characteristics and yield,to research intercropping maize.The studies have shown that:intercropping maize chlorophyll content can be functional within the blade lift,change the structure of chlorophyll,improve net photosynthetic rate significantly.Intercropping maize improved light compensation point,light saturation point,light saturation maximum net photosynthetic rate,apparent quantum yield and carboxylation efficiency,so that CO2 compensation point decreased significantly.Intercropping maize growing significantly enhanced post-plant dry matter,accel-erated grain growth, significantly improved corn yield equivalent area ratio higher than its share,reflecting a significant intercrop-ping yield characteristics.
