Abstract: Soil fertility status has a direct effect on grape yield and quality analysis of nutrient content, the author collected the soil sample data of ten core production region form table grape base in Binchuan County, Yunnan, to do the research. It focused on the analysis of fertility indicators, like pH, organic matter, nitrogen, phosphorus and potassium, meanwhile, evaluated the soil fertility characteristics in this base based on the Nemerow fertility index. The results showed as follow: the soil pH was unsuitable in table grape base of Binchuan County, because the soil status partial acid level, the average value was 5.87, the organic matter content was at a low level, the average value was 1.09% ; the total amount of nitrogen, phosphorus and potassium were at a high level overall while showed a nutrient regional imbalances. Nitrogen content in the superior level, the available phosphorus, potassium content in the high level, the sampling points were relatively large changes. According to the Nemerow fertility index, soil fertility in base was levelⅠwhich was rich. Soil individual fertility index of organic matter were in the lower level, at the same time, other indicators were in the general fertility level or higher fertility levels. As a result, people can improve the soil fertility of raw material base in Binchuan County table grape from organic fertilizer, soil testing and increased application of farmyard manure or lime to conduct targeted fertilization and adjust the soil pH.
