The negative influence caused by the seasonal drought was serious in the citrus orchard in Southern China.Therefore, there was an emergency need for the research of soil moisture management and soil erosion control measurements in the citrus orchard. In this paper, three citrus orchard plots with typical soil erosion control measurements such as biological measurement, tillage measurement and engineering measurement were employed as the subjects, which located in the Jiangxi Provincial Soil and Water Conservation Eco-science Park. The soil moisture of 30 cm soil layer was analyzed, and the soil water productivity vary months were calculated. The results show that the plot of engineering measurement presented the highest soil moisture of 30 cm soil layer, and also the highest capability in runoff trapping and soil water productivity. And the point that all the three soil erosion measurements show high capability in soil water productivity, which was important in citrus orchard water management.
