Where are oranges abundant in China?

Citrus in China is mostly distributed in the middle and lower reaches of the Yangtze River and the south of the Yangtze River between north latitude 16 ~ 37. Citrus is mainly produced in Zhejiang, Fujian, Hunan, Sichuan, Guangxi, Hubei, Guangdong, Jiangxi, Chongqing and Taiwan Province provinces 10 provinces (cities, districts), followed by Shanghai, Guizhou, Yunnan and Jiangsu provinces (cities), and also cultivated in Shaanxi, Henan, Hainan, Anhui and Gansu provinces. Citrus is grown in 985 counties (cities, districts) in China.

The famous citrus producing areas in China are Wenzhou tangerine in Shimen, Hunan, Ponkan in Xiangxi, Sweet orange in Huaihua, Shatang tangerine in Sihui, Nanfeng tangerine in Jiangxi, navel orange in Gannan, Citrus in Yichang, Hubei and Ponkan in Quzhou, Zhejiang.

Production environment of oranges

1, temperature: The growth and development of citrus fruits need the temperature of 12.5 ~ 37℃, and the day and night temperatures of flower bud differentiation in autumn are about 20℃ and 10℃ respectively, and the soil temperature for root growth is roughly the same as that above ground. High temperature is also not conducive to the growth and development of citrus. When the air temperature and soil temperature are higher than 37℃, the growth of fruits and roots will stop.

2. Illumination: Oranges are shade-tolerant trees, but good sunshine is needed for high quality and high yield. Generally, areas with annual sunshine hours 1200 ~ 2200 hours can grow normally. For example, South China with good sunshine and abundant calories has higher sugar content, lower acid content and higher sugar-acid ratio than Chongqing citrus producing area with less sunshine.

3. Humidity: Citrus is suitable for planting in tropical and subtropical areas with annual rainfall of about 65,438+000mm mm.. The relative water content of soil is 60-80%, and irrigation is needed if it is lower than 60%. Excessive rainfall will cause soil water accumulation or high groundwater level, and root system death will occur in citrus orchards with poor drainage.

4. Soil: Oranges can adapt to a wide range of soil. Purple soil, red and yellow soil, beaches and beaches can all grow at ph 4.5 ~ 8, and the most suitable ph is 5.5 ~ 6.5. The soil with high oxygen content, loose texture, good structure, organic matter content of 2 ~ 3% and good drainage is the most suitable for root growth.
