Abstract
In this paper,comparison the different density under of leaf area index,dry matter accumulation of dynamic change ,and the influence of the density of maize grain yield of zhengdan958. The result show that leaf area index was low,dry matter accumulation was largest,but insufficient amount of population dry matter accumulation under the 45 000 plants / ha. Leaf area index was falling faster,not condition to the accumulation of dry matte in 90 000 plants / ha. In this experiment,the maximum yield is the density of 67 500 plants / ha, leaf area index early was rising fast,slow down,more dry matter accumulation in the late for grain growth,the highest yield.关键词
