Studies on Population Structure of High Yield in Vegetable Soybean

Yield,plant characters and population growth of vegetable soybean variety“292”under different plant densities and plants perhole were analy zed and the indexes of the population structure of high yielding vegetable soybean were summa rized.The results showed that the density of 232.5～240.0 thousand plants perhm 2 and 1～2 plants perhole planting were suitable.High peak value of LAI was about 3.8,and appeared in pod setting stage.The weight of dry matter per plant in fresh pod picking stage reached 27 g,which occured in the pods over 42 percentage. The results were tested and verified in the field pro duction.
