There are affluent water and thermal resources in latored soils of south subtropical hilly area，which has an advantage to develop tropical fruit and vegetables like litchi，longan，banana，mango and so on.An introduction of natural conditions of south subtropics，superiority of south subtropics in Guangdong Province and characteristics of latored soils region is presented in this paper.But the soil water storage capacity and the available water content are very little，combined with low unsaturated hydraulic conductivity and hydraulic diffusivity because of the restriction of climate factors.Some biological or engineering technical measurements of regulating and managing soil moisture properly are advised to improve soil and prevent or lessen soil evaporation.
