In order to explore the technical measures to reduce nitrogen and phosphorus loss in intensive orchards and slow down agricultural non-point source pollution, this study compared and analyzed the effect of drip fertigation and plant hedgerows on reducing nitrogen and phosphorus loss in surface runoff and improving the water quality in field ditch based on field positioning experiments. The results showed that the plant hedgerows increased the minimum daily rainfall of surface runoff, and reduced the frequency of runoff. The amount of surface runoff was reduced by 19.18% compared with the treatment without plant hedgerows. Compared with CK treatment, the TN and TP concentrations in runoff water of the drip fertigation treatment decreased by 31.23% and 25.18%, respectively. The TN and TP concentrations in the plant hedgerows treatment decreased by 16.74% and 13.60%, respectively, and the TN and TP concentrations in the treatment of drip fertigation + plant hedgerows decreased by 52.32% and 43.89% than the CK treatment, which were the lowest in all treatments. The loss fluxes of TN and TP in the treatment of drip fertigation + plant hedgerows decrease by 45.38% and 36.81%, respectively, compared with the CK treatment. In the treatment of drip fertigation + plant hedgerows, the TN and TP concentrations in the ditch water decreased by 23.98% and 26.64%, respectively, compared with the CK treatment. These results indicated that the implementation of drip fertigation combined with plant hedgerows in intensive farmland such as orchards can effectively reduce nitrogen and phosphorus loss in runoff and slow down the discharge of agricultural non-point source pollutants, which has great prospects in practical applications.
