Abstract

Abstract: In order to control non-point source pollution from the development and management practice of orchard, by choosing a large-scale navel orange planting orchard as the research base, the controlling measures for non-point source pollution from orchard in Dongjiang river source were established according to the best management practices （BMPs） theory. Results revealed that, compared with that from the contrasting area （clean tillage treatment）, after taking BMPs, concentrations of TP, TN and NH₄⁺-N in runoff from testing area in the orchard were reduced by 27.78%, 57.93% and 88.89% respectively, and the interception effect of TN and NH₄⁺-N in the runoff was very significant（P<0.01）.

Key words: non-point source pollution, orchard, best management practices, Dongjiang river source areas
