Abstract：Taking Chinese cabbage variety “Beijing New No.3” as material, the effects of coated control -release-urea and nitrification inhibitor on its yield and quality were studied under open -field condition.The results showed that, compared with conventional fertilization (FP), the self -made control -release-urea ( CRF-Ⅰ) could significantly increase the yield of Chinese cabbage by 6 .4%.The sold control-release-urea (CRF-Ⅱ) and nitrification inhibitor (DCD) decreased the yield of Chinese cabbage slightly by 1.48%and 2.09%respectively, and there was no significant difference .Compared with FP, CRF-Ⅰ、CRF-Ⅱand DCD could improve nutritional quality , such as the contents of vitamin C , amino acid , reductive sugar and crude protein , and decrease the nitrate content in Chinese cabbage leaves .
