As an important part of the characteristic agriculture in Yunnan plateau，Chu orange has high edible and economic values. In order to fully understand the status of soil nutrients and fruit quality indicators of Chu orange orchard，samples of fruits，0~30 and 30~60 cm soil layers were collected in the 16 hectare planting demonstration area in Xinping Chu orange orchard，Yuxi city. The fruit quality indicators and soil physical and chemical properties were tested and analyzed to explore the relationship between fruit nutrients and soil nutrients in Chu orange planting demonstration area. The results showed that:(1) The contents of organic matter，available phosphorus and available iron in the soil of the orchard planting demonstration area were suitable for the growth of Chu orange，and the soil was at the sufficient selenium level. The fruit quality and selenium content of Chu orange were stable，but there was still space for improvement. (2) Compared with 30~60 cm soil layer，the contents of nutrient elements in 0~30 cm soil layer had a greater impact on fruit quality and nutrient elements. (3) The optimum range of soil Zn，Fe and Ca contents for improving the quality of Chu orange was 1.46~2.61，15.58~21.02 and 1410.94~1998.44 mg·kg-1，respectively.
