摘　　要：通过采用大垄双行的种植方式,在不同密度下对3种株型的玉米建立不同的群体冠层结构,并测定了其光合特性。结果表明:大垄双行种植玉米可改善冠层中下层叶片的光照条件,提高叶绿素含量,可使中下层叶片光合速率增加5%～10%,气孔导度增加10%左右。Three type maize colony were planted by double lines at one width ridge in different planting density, and photosynthetic characteristic were he measured. The result showed： Photo flux condition of middle and under layer leaf of maize were improved by double lines at one width ridge. Photosynthetic characteristic of middle and under layer leaf were elevated 5% - 10%, chlorophyll content were enhanced, Stomata conductance were increased about 10% approximately.
