Leaf Character was studied under five different densities with two colored rice of black glutinous （Y4） and red japonica （YS）.The results indicated that with increasing planting density, the dry weight of leaves of colored rice was increased, leaf area index was increased and then deceased with a mono peak variation, the angle and chlorophyll content on the top three leaves were increased. The suitable density of Y4 and Y5 is respectively 120, 000/666.7 m^2 and 160,000/666.7m^2, moreover, the durability to density of Y5 is stronger than Y4.
