Abstract:
Abstract The effect of plant density on the changing trends o f plant heig ht and leaf area index(LAI), leaf area duratio n , dry m atter accum ulation and distribution , yield o f Heinong 41 w ere studied under the condi-tion o f hig h yield in Xinjiang in this experiment. The result show ed tha t plant height , LAI and leaf area duratio n were heightened alo ng w ith the increase o f density . The difference of leaf area dura tion of differ-ent manag ements w as the largest w hile podding. T he colo ny accumulatio n difference o f different manag e-m ents appeared after podding . Improving the leaf a rea duratio n o f colony and increasing the matte r product w hile podding are the key for o btaining high yield of soybean. The com prehensive perfo rmance of 45 ×104 plants per hm2 w as the best , with the y ield o f 5547. 81kg per hm2 and dry m atter accum ulation of 14663. 1 kg per hm2 .
