Abstract: The results of our studies showed that the basic nutrient status of the soil in high-yielding Lonyan orchard is maintained at an optimum level in the six major production areas in Fujian Province.The content of a few nutrient elements(Mg, P)are somewhat lower.We therefore lay emphasis on the importance of enhancing soil fertility.Furthermore,the data also showed that there was significantly or more significantly positive correlation among most of the basic nutrientcontents.These findings indicated that the patterns of soil fertility is in a balanced state.The present paper suggests the optimum range of the basic nutrient contents in the soil of high-yielding Lonyan orchard in Fujian.These criteria may provide the parameters for evaluating soil fertility and nutrient diagnosis of Lonyan orchard.
