The experiment studied soybean law of nitrogen absorption, distribution and transferring under different density and fertilizer treatment, taking BeiFeng-14 as test variety and adopting 5 factors and 3 levels treatment. The result is as following: As growth of soybean, the nitrogen concentration in each soybean organ is descending except for seed; moreover, leaf’s nitrogen is always larger than stem and leafstalk. The largest absorption rate appears form pod- setting to pod- filing, which is 15.17mg /d individual plant.
