Field experiment was carried out on flowering chinese cabbage with different fertilizer treatments，and the related indexes such as yield and quality were investigated,and then the economic benefit was analyzed.The results showed that the highest yield and the lowest economic benefit occurred in the regular fertilizing,due to its highest amount of fertilizer application,with the highest content of nitrates and the lowest content of vitamin C.The highest income and input output ratio were obtained in the special formulated fertilizer treatment.The former was 164% higher than the regular fertilizing treatment,while the latter was 405 times higher than that.The best quality was got in the treatment,which combined application of chemical fertilizer,organic fertilizer and soil conditioner.The nitrates content was reduced by 314%,while vitamin C content was increased by 221% compared with the regular fertilizing treatment.
