In order to better promote the innovation and development of soil and water conservation technology,promote and demonstrate new technologies for soil and water conservation in orchards,and promote the high-quality development of the fruit industry,it was studied the effects of integrating several soil and water conservation technologies by the runoff plot method in honey pomelo orchards,such as strip shaped grass,collecting channels,covering with grass prevention cloth,and fertilization pipes,etc.The results show that the integration of technology can significantly reduce orchard runoff more than 40.0％.The application of strip grass+anti grass cloth+drainage channel management in orchard with least runoff can reduce the loss amount of nitrogen and phosphorus by 70.7％-96.7％ and 81.2％-97.9％ respectively.The various measures arranged can significantly reduce soil erosion.The measures of strip grass+anti grass cloth+catchment channel and strip grass+anti grass cloth+fertilizer pipe are very effective,accounting for 16.7％ and 22.2％ of the natural grass erosion amount respectively.The impact is not significant in the 5-10cm soil layer of the orchard,while the soil moisture content has a significant impact in the 25-30cm soil layer.The measure of Ribbon grass+anti grass cloth+fertilizer pipe increases the soil moisture content in the natural grass growing area by 22.80％,with a very significant effect.The measure of Ribbon grass+anti grass cloth+flow channel increase the soil moisture content in the natural grass growing area by 14.43％,with a significant effect,while it has no significant effect on the leaf weight and nitrogen and phosphorus content of honey pomelo.
