| 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。

| Abstract: | Three type maize colony were planted by double lines at one width ridge in different planting density,and photosynthetic characteristic were be 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. |

| Keywords: | Maize Double lines width ridge Canopy structure Photosynthetic characteristic |
