The nitrogen is one of a large number of nutrient elements required by plant growth and development, the yield and the quality of the soybean are directly influenced, although the soybean can fix the nitrogen in the atmosphere by the nodule, the experiment proves that the nitrogen fixed by the nodule can only meet 1/3-1/2 which needs the nitrogen in the life of the soybean, so the high yield of the soybean cannot be obtained by the nitrogen fixation effect of the nodule in most cases. This is the important reason that some peasant households always have soybean yield of 200-. In order to obtain high yield, nitrogen fertilizer is also applied during the growth of soybeans. However, the growth of the nodule is influenced by excessive application of the nitrogen fertilizer, the nitrogen fixing capacity of rhizobia is reduced, and the nitrogen fertilizer is wasted; too much nitrogen fertilizer can cause the soybean to grow too luxuriantly, so that the flower and pod fall is delayed or the soybean is greenish and lodging is caused. Therefore, the application of nitrogen fertilizer must be well controlled according to local conditions.
