Which terrain is not suitable for building citrus orchards?

This barren land is not suitable for building citrus orchards. High altitude is also not suitable for building citrus orchards. Generally speaking, the temperature drops by 0.6~0.7℃ every time the altitude rises 100m. Therefore, in the south subtropical and tropical climate areas where the temperature is too high to grow citrus, it may be suitable to grow citrus in the mountainous areas with higher altitude. In areas with low temperatures, citrus orchards should be built at lower altitudes, not in high-altitude mountainous areas.
