Abstract：The field trial of nitrogen fertilizing level of flowering Chinese cabbage was conducted at 17 testing point with different soil nitrogen level,and the correlation was analysed between production and alkaline hydrolysis nitrogen content in soil for establishing regression equation.The results showed that production and alkaline hydrolysis nitrogen content was parabola correlation.Planted in medium loam it was unnecessary to supply nitrogen fertilizer to soil when the nitrogen level was 146-277 mg·kg~ -1 or ...
