Based on the fertilization management mode of organic fertilizer combined with chemical fertilizer,this study summarized a set of technical methods for fast fertilizing and high yield fertilization in low soil fertility fields under winter wheat-summer maize rotation in Beijing.This model was applied to the experiment in Miyun and Shunyi,and three treatments were set,including single fertilizer treatment,fast fertilizing treatment and high yield fertilizing treatment.The results showed that the yield of fast fertilizing treatment only increased about 1％-2％,but the soil organic carbon content increased about 1.06 g/kg in Miyun and 0.96 g/kg in Shunyi.The yield increase rates of high yield fertilizing treatment reached 9.9％(winter wheat)and 11.5％(summer corn)in Miyun,10.9％(winter wheat)and 10.1％(summer corn)in Shunyi,respectively,but the soil organic carbon content only increased 0.06 g/kg in Miyun,while it did not increase Shunyi.This study provides a fertilization strategy that can increase crop yield and improve soil quality for low-fertility grain fields in the suburbs of Beijing.
