The effect of different concentrations of urea and photosynthetic bacterial fertilizer on growth and quality of Chinese chive was studied. The results showed: appropriate use of urea and photosynthetic bacterial fertilizer played an important role in improving growth and quality of Chinese chive. When photosynthetic bacterial fertilizer 200×and urea 10 kg/667m2 were used together, Chlorophyll a, Chlorophyll b, ratio of dry and fresh weight were the max compared to control, and the content of Soluble sugar, soluble protein and Vc was very significantly higher than control, but the content of nitrate and crude fiber was significantly lower compared to control respectively.
