Abstract:: Taking mung beans seeds as materials,the effects of different exogenous nitrogen (urea) 0.05%，0.10%，0.20%，0.50% on nitrogen metabolism and quality during the germination of mung bean seeds were studied.The results showed that with the urea concentration increasing，yield showed the tendency of increase first and then decrease，but did not show significant difference;the contents of protein and soluble sugar tended to increase first and then decrease.The content of free amino acid and nitrate nitrogen showed increasing content.The content of nitrite in mung bean sprouts were decreased with germinating time running，but their ranges were different.The nitrate nitrogen concentration of mung bean sprout were seriously exceeded food safety standard (432 mg/g) in the treatments of high urea application.
