Where is it suitable to grow oranges, and what are the common varieties?

Orange is a type of mandarin fruit, a hybrid of pomelo and tangerine, with high edible and medicinal value. Oranges have a long history of cultivation, and because their peel contains a fragrant aroma, the ancients used it as a substitute for incense. So where is it suitable to grow oranges? What common varieties are there? Let's take a look together with the editor below.

1. Where is it suitable to grow oranges?

The growth and development, flowering and fruiting of oranges are closely related to environmental conditions such as temperature, sunlight, moisture (humidity), soil, wind, altitude, topography and slope aspect. In China, oranges are suitable for planting in southern Gansu and southern Shaanxi, southern Jiangxi, Sichuan, Hubei, Hunan, Jiangsu, Guizhou, Guangxi, Guangdong and the mountainous areas of northeastern Yunnan.

2. Main varieties of oranges

1. Sweet orange

Also called sugar orange or acidless sweet orange, it mainly includes varieties such as Bingtangcheng, red-fleshed navel orange, Chucheng, Sunkist orange and summer orange, and the fruit shape is similar to ordinary sweet oranges. Because the acid content is extremely low, it can be harvested and marketed once the juice content reaches an appropriate level, making it an extremely early-maturing sweet orange variety. There is a small amount of production along the Mediterranean coast and in places such as Brazil, supplying local markets.

2. Navel orange

Navel oranges mainly include varieties such as Gannan navel orange, Xinfeng navel orange, Xunwu navel orange and Lunwan navel orange. The fruit is larger than ordinary oranges, generally has no seeds, is parthenocarpic, and is easier to peel. Therefore, navel oranges are more suitable for fresh eating. The main feature is that there is a conical secondary fruit inside the fruit, characterized by a navel at the top of the fruit, that is, an underdeveloped small fruit embedded at the top of the fruit.

3. Blood orange

Generally even smaller than oranges, it gets its name mainly because the flesh and juice are red due to the presence of anthocyanins. It mainly includes varieties such as Tarocco blood orange, rose blood orange and Hongyu blood orange. The flesh and juice are entirely purplish red or dark red, and after cutting, they show thread-like blood streaks, with plenty of moisture. The flesh is tender and juicy. Because blood oranges are rich in a large amount of VC, they have a sweet-and-sour taste. Overall, comparing them, Sister Youliao thinks they are tastier than pomelos.

4. Red orange

Red oranges are mainly produced in Zhanjiang, Guangdong and Lianjiang. Lianjiang red orange fruit is large (a single fruit weighs about 150 grams), with good fruit shape, orange-red flesh, tenderness and smoothness, juicy and melting pulp, sweet with a hint of sourness, and a clean sweet taste with fragrance. It is deeply welcomed and is therefore listed as an excellent fruit for state banquets, and because of this Lianjiang has been named the "Hometown of Chinese Red Oranges".

The above is an introduction to oranges. China has many orange varieties, and the differences in maturity periods are also relatively large. According to fruit maturity, they are divided into early-, mid- and late-maturing types. Farmers who grow oranges can determine the harvest time according to the maturity of the orange fruit, its use, market demand and so on.
