Abstract: In order to make clear about the Nitrogen and Phosphorus runoff-losses in bean-planted that bean is planted by the normal farmers and used the normal fertilizer, a field trail was carried out to investigate characteristics of nitrogen and phosphorus runoff-losses in bean-planted region along the Huaihe River of Anhui Province during the bean growing season using surface runoff ponds from 2008 to 2012. The results of five years experiments showed: the season of bean growing was in an abundant rainfall period of every year, about 45.4%-73.27% of volume rainfall of whole year. The results of the volume of surface runoff showed CK > CF during the bean growing season, the volume and rate of rainfall of CK were 173.293-34.639 mm and 8.27%-33.68%, the statistics of CF were 175.366-30.347 mm and 5.72%-34.08%. The concentration of total nitrogen and TN runoff rate of N-fertilizer of CF during the bean growing were 1.58-14.93 kg/hm2 and 0.44%-5.66%, NO3-/TN of surface runoff was 40.63%-64.59%, NH4 /TN of surface runoff was 3.66%-18.16%. The concentration of total phosphorus and TP runoff rate of P-fertilizer of CF during the bean growing were 0.033-0.56 kg/hm2 and 0.17%-0.27%, DTP/TP of surface runoff was 31.08%-53.31%.
