Effect of Density on the Agronomic Character and Yield of Vegetable Soybean

This experiment studied the variety of the agronomic character,dry matter accumulation,LAI and quality different densities of vegetable soybean.The study result showed that the plant height was increased with density increasing,stem thick,nodes,the branch number,the length of branch decreasing;pots plant,seeds plant,seeds weight plant was decreased with the density decreasing,the max accumulation of dry matter was decreasing.The relation of 100 seeds weight and quality wasn't significant with plant density.The yield of 21×10~4/hm~2 was the highest,yield was 15 523.05 kg/hm~2.
