Cinnamon Soil was used to study the effects of heavy metal cadmium and zinc contamination on the nutritional quality of non-heading Chinese cabbage with pot culture. The results showed that under single cadmium or zinc treatment the content of chlorophyll, reducing sugar and vitamin C gradually decreased with the levels of cadmium or zinc added in soil. The content of crude protein dropped when cadmium or zinc concentration was low and rose when it was high. The content of crude fibre decreased with low concentration and increased with high concentration of zinc and it increased with the levels of added cadmium. Under complex cadmium and zinc treatment, zinc cooperated with cadmium to improve the content of crude protein and reduce the content of chlorophyll, reducing sugar and vitamin C. Zinc counteracted cadmium to affect the content of crude fibre.
