Citrus fruits are generally distributed in southern and southwestern regions of China. This distribution is mainly due to the following reasons:
Climate: Citrus fruits thrive in regions with a subtropical to tropical climate. Southern and southwestern China have warm temperatures year-round, providing ideal conditions for citrus cultivation.
Sunlight: Citrus trees require plenty of sunlight to grow and produce sweet fruits. These regions receive a sufficient amount of sunlight throughout the year, which is essential for the fruit development process.
Moisture: Citrus trees need well-drained soil and consistent moisture for optimal growth. The southern and southwestern regions of China often receive a moderate amount of rainfall, providing the necessary moisture for citrus cultivation.
Altitude: Citrus trees prefer to grow at lower altitudes. The regions in southern and southwestern China where citrus is commonly cultivated are at suitable altitudes for citrus production.
Tradition: Citrus cultivation has a long history in these regions, and farmers have developed expertise in growing different varieties of citrus fruits. The availability of skilled labor and knowledge of citrus farming practices also contribute to the widespread distribution of citrus in these areas.
These factors combined make southern and southwestern China favorable regions for the cultivation of citrus fruits, leading to their widespread distribution in these areas.
