Abstract:: Chinese cabbage ‘Jing Xia Wang’ and fertilizer synergist were used as the test malerials，and the field plot experiment was conducted to explore the effect of fertilizer synergist on the yield and quality of Chinese cabbage and fertilizer utilization ratio according to the different application amounts of N and P fertilizer.The results showed that the fertilizer synergist increased output of Chinese cabbage.Under the condition of same amount of nitrogen fertilizer，fertilizer synergist increased the output of Chinese cabbage by 11.99%.However，under the condition of same amount of phosphate fertilizer，fertilizer synergist increased the output of Chinese cabbage by only 7.40%.Fertilizer synergist significantly improved the utilization ratio of nitrogen and phosphate fertilizer by 12.38% and 5.34%，respectively.In addition，fertilizer synergist decreased nitrate content in Chinese cabbage to improve its quality to some extent.
