本研究通过试验证明，紧凑型玉米品种除具有茎叶夹角较小，适于密植，可增加亩穗数而提高产量外，还具有比平展型品种更高的单株生产力、高叶绿素含量、高光合速率等，在低密度条件下也可比平展型品种增产。生产上应用的紧凑型高产玉米品种是高配合力与理想株型的完美结合。是具多种优良性然的高光效品种类型。 In this study, we proved that the compact maize varieties had the characteristics of higher plant productivity and higher chlorophyll content than the flat varieties, except for the smaller angle between stems and leaves, suitable for close planting, High photosynthetic rate, etc., in low-density conditions can also increase than the flat-type varieties. The compact, high-yielding maize varieties used in production are the perfect combination of high co-ordination and ideal plant type. With a variety of excellent natural high-light type of species.
