| Abstract: | Objective ] The relationship between the amount of nitrogen application and nitrate content in Chinese cabbage leaf was studied to control nitrate content in rape leaves. Method] Potted experiments were used to study the influence of nitrogen intensive gradient on the ni- trate content in Chinese cabbage. Result] The nitrate content in stalk and leaf of Chinese cabbage was increased accordingly with the nitro- gen fertilizer increasing. Conclusion] To reduee nitrate content, the application amount of nitrogen fertilizer should be controlled. |
