Abstract
A pot experiment was carried out to explore the effect of combined fertilization of K, Zn, and N on nitrate accumulation in chinese cabbage during different growth periods and the relationship between nitrate content and the activity of nitrate reductase(NR). The results indicated that N fertilizer application was the main factor in increasing nitrate content. Optimally combined application of K, Zn and N fertilizers improved NR activity and decreased the nitrate accumulation in chinese cabbage significantly. There was a significantly negative correlation between nitrate content and NR activity. During the latter period of growth, K and Zn fertilizers decreased the accumulation of nitrate effectively.
