摘      要：Since 2005,the application of nano carbon(NC)in agriculture and environmental remediation has received considerable attention with most of the research focusing on plant growth and heavy metal ***,little is known about the potential effects of NC on soil erosion and nutrient *** this study,rainfall simulation tests were conducted on a soil plot(1 m×1 m,located in a semi-arid loess region of northwestern China),in which a mixture(5-cm below the soil surface)of NC(0,0.1%,0.5%,0.7% and 1.0% on a mass base)and sandy soil(same as the one in the plot)was embedded as three bands(5 cm wide,1 m long and 5 cm thick)at the three positions(top,middle and bottom of the plot),*** the rainfall simulation test,a mixed solution of potassium bromide(1.0 mol/L KBr),potassium nitrate(1.0 mol/L KNO_(3)),monopotassium phosphate(1.0 mol/L KH_(2)PQ_(4))was sprayed on the soil *** showed that the sandy soil on the Loess Plateau with 0.7%NC addition(36.47 kg/hm^(2) on a mass basis)could improve soil water runoff,sediment yield,and nutrient loss in the semi-arid loess region of northwestern China,in addition to preventing soil water from deep ***,NC may have a great potential in soil erosion control on the Loess Plateau of China.
