The best way to preserve oranges

Oranges can be stored directly at a cool and ventilated room temperature, but the water stains on oranges need to be dried.

If the weather is hot, you can store oranges in the refrigerator, which can remove the odor in the refrigerator. Or put the oranges directly into the cellar for preservation, or they can be preserved for a long time.

Oranges taste sweet and sour, and are cool. They contain a lot of vitamins, protein, cellulose and nutrients such as calcium, iron and phosphorus. The rash is thick and can be stored for a long time at room temperature. Fresh and high-quality oranges can be kept at room temperature for at least half a month.

Oranges can be stored in the refrigerator, which can help oranges inhibit the growth of harmful substances such as bacteria at low temperature. Therefore, the shelf life and fresh taste of oranges can be prolonged, so oranges can generally be stored in the refrigerator for 1-2 months.

Growth habits of oranges

The growth, development, flowering and fruiting of citrus are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil, wind, altitude, topography and slope direction, among which the temperature has the greatest influence.

Even though the temperature sometimes varies greatly, the most suitable temperature for citrus growth is 37℃. When flower buds differentiate in autumn, the temperature of day and night is required to be about 20℃ and 10℃ respectively. Too low a temperature will freeze oranges. In addition, 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, and they are wild and cultivated in mountainous areas of Gansu, southern Shaanxi, southwestern Jiangxi, Sichuan, Hubei, Hunan, Jiangsu, Guizhou, Guangxi, Guangdong and northeastern Yunnan. The southern part of Wuling is barren, and it is a citrus widely distributed in the north. Cold-tolerant, some varieties are semi-deciduous.
