In order to establish a reasonable Zinc and Manganese fertilizer proportional scheme and to improve the yield and quality of vegetables, a field experiment was conducted on calcareous cinnamon soil of Shanxi province to study the effects of Zinc and Manganese fertilizer on yield and quality of Chinese cabbage (Brassica campestris ssp. chinensis) based on the N, P, K prescription fertilization. The results showed that appropriate application of Zinc and Manganese fertilizer could increase the yield and quality of Chinese cabbage remarkably, and there were significant interaction effects between Zinc and Manganese fertilizer and the yield and quality. Adding the Zinc and Manganese fertilizer, the yield and content of Vc, reducing sugar, Zinc increased by 16.5%-64.4%, 58.8%-116.8%, 29.1%-65.3%, 120.9%-300% respectively, and nitrate content decrease by 2.0%-27.2%. For the higher yield and better quality of Chinese cabbage, the optimum applied amount was: Zinc sulfate 75-120 kg/hm2, Manganese sulfate about 75 kg/hm. , considering the applied rates that N, P and K were used 400 kg/hm2, single super phosphate 200 kg/hm2, potassium sulphate 200 kg/hm. ._
