It is located between 24 29' ~ 27 09' north latitude and113 54' ~116 38' east longitude. Ganzhou City is a hilly and mountainous area with a mountainous area of 45.6 million mu, which is located at the southern edge of the middle subtropical zone and has mountainous resources for planting navel oranges.
Ganzhou mountainous area is dominated by Quaternary red soil, with a small amount of purple soil and mountain yellow soil. The soil layer is deep, and a high standard navel orange orchard can be built with a little modification. The soil condition is good. Red loam has the characteristics of deep soil layer, acidic soil and low organic matter content, which is suitable for navel orange growth. A large number of shallow hills and slopes provide conditions for Ganzhou to develop a large-scale fresh navel orange base.
Secondly, Ganzhou is phyllite weathered loam with a depth exceeding 1 m, which is loose and breathable. There are many trace rare earth elements in soil (rare earth elements play an irreplaceable role in the formation of fruit pigment, the increase of sugar, vitamin C and aroma, and the improvement of crispness and storage resistance).
