Investigations on the rock-soil geochemical system for the producing area of 'Zhonghuashoutao' peach have been performed in Laixi county.The results show obvious differences of geochemical characteristics in this rock-soil system. Some elements are rich in specific rocks,(e.g. K2O and Na2O in granite, B in base rock, MgO and CaO in canaanite and Mn, N and P in leptite). As a result, the related soils have the similar geochemical characteristics, whereas the tendency of variations for these elements is not significant .The nutrient elements which are needed for peach trees are found quite different in different soils. For instance , canaanite and base rocks are abundant in Ca, Mg, Mn, N and P, while leptite is sufficent in N, P, Fe and B. However, the nutrient elements are found insufficently in the large grantite soil areas.The effective elements of N and P have high levels in the soils of peach gardens, while B Mn, Mo, Fe and organic matters are relatively low in concentrations. It is suggested that beside the enough N, P and K, some trace elements such as B, Mn, Mo, Fe, Ca, Mg as well as organic fertiltzers must be used to improve the soil quality.
