Abstract:
The experiment was carried out by using twelve soybean cultivars from different regions in 2006. And the cultivars were divided into three groups：Ohio current cultivar(OCC)，Liaoning current cultivar(LCC) and Liaoning old cultivar(LOC). Three level of 0，150 and 300 kg.ha-1were applied as starter fertilizer.The effect of fertilizer on nitrogen accumulation and distribution of soybean cultivars from different regions were discussed.OCC had the maximum nitrogen accumulation speed，and their appearance time was the earliest among three group cultivars.Compared with the no fertilizer treatment，fertilizer could increase the average accumulation rate of nitrogen，and the increasing range，OCC was smallest，LCC and LOC were bigger.OCC had the highest nitrogen contents in stem，Leaf，and whole plant，then was LCC，and LOC the lowest.Compared with the no fertilizer treatment，in the early stage，fertilizer could accelerate the nitrogen absorption and increase the nitrogen content of stem，leaf and whole plant，and the increasing range from higher to lower was OCC，LCC and LOC.In the later stage，fertilizer would transfer more nitrogen to and increase the nitrogen content in seed and pod.Compared with the no fertilizer treatment，the nitrogen content of OCC was the highest under the fertilizer level of 150 kg.ha-1，and the nitrogen centent of LCC and LOC were the highest under the fertilizer level of 300 kg.ha-1.
