Abstract: In order to improve the availability of soil phosphorus and reduce the input of fertilizer phosphorus in North China, the effects of different spring Brassica campestris L. overturning on soil phosphorus supply capacity and phosphorus uptake of subsequent corn were studied. The results showed that, compared with fallow fields in spring, overturning spring Brassica campestris L. could significantly increase the phosphorus content of the soil(P<0.05) and increase the phosphorus supply capacity of the soil. Among the tested corn varieties, Zhongyoufei 1804, Zhongyoufei 1901 and Zhongyoufei 1907 had higher biomass and higher phosphorus content in hectares of plants, the total phosphorus, available phosphorus, and alkaline phosphatase content in the soil after overturning were higher than the remaining other tested varieties (Zhongyoufei 1, Zhongyoufei 2, Zhongyoufei 1802, Zhongyoufei 1903, Zhongyoufei 1904, Zhongyoufei 1906). After overturning the spring Brassica campestris L., the 100-grain weight and yield of subsequent corn were both higher than contrast. Moreover, the 100-grain weight and yield of corn under the treatment of Zhongyoufei 1804((44.60±1.89)g, (15 321.82±2 150.29)kg/ha), Zhongyoufei 1901 ((44.81±0.68)g, (15 634.70±1 201.92)kg/ha) and Zhongyoufei 1907((43.69±1.78)g, (12 931.07±2 787.86)kg/ha)were significantly higher than other treatments. Therefore, Zhongyoufei 1804, Zhongyoufei 1901 and Zhongyoufei 1907 were selected as suitable spring Brassica campestris L. varieties for planting in North China.
