Abstract: The influence of densisties on growth and yield of Zhengdan22 was studied. Leaf area per plant and dry matter accumulation per plant were dropped by densities increasing. Leaf area index and dry matter accumulation were increased by densities increasing and dropped by high densities. The yield was increased by densities increasing. The results showed that the suitable planting densisty of Zhengdan22 is 45000~52500 plants/hm2.
