Orange grows where the pictures and sketches are as follows:

Where it grows:

China's oranges are distributed between latitudes 16 to 37 ° north, the highest elevation up to 2,600 meters (Batang, Sichuan Province), from the south of Sanya, Hainan Province, to the north to Shaanxi, Gansu, Henan, east of Taiwan Province, and west of the Yarlung Zangbo River Valley in Tibet. However, the economic cultivation area of citrus in China is mainly concentrated between 20 and 33° north latitude, at an altitude of 700 to 1000 meters below.

There are 19 provinces (municipalities and autonomous regions) producing mandarin oranges, including Taiwan Province, of which the main mandarin oranges are produced in 10 provinces (municipalities and districts), such as Zhejiang, Fujian, Hunan, Sichuan, Guangxi, Hubei, Guangdong, Jiangxi, Chongqing and Taiwan, followed by Shanghai, Guizhou, Yunnan, Jiangsu and other provinces (municipalities), and also planted in Shaanxi, Henan, Hainan, Anhui, and Gansu, etc. The whole country is planted with mandarin oranges. There are 985 counties (cities and districts) growing mandarin oranges.

The world distribution of oranges:

The world's oranges are mainly distributed in the region south of 35° north latitude, sex like warm and humid, with a large body of water warming the territory can be pushed northward to 45° north latitude. There are 135 countries in the world to produce oranges, annual output of 102.822 million tons, an area of 107.3 million acres, are in the top of the fruit, the production of the first number of Brazil, 24.252626 million tons, the second number of the United States, 16.3352 million tons, China's third, 10.78 million tons, and then after Mexico, Spain, Iran, India, Italy and other countries.

Oranges origin environment:

1, temperature: orange fruit growth and development requirements of 12.5 ~ 37 ℃ temperature, the fall bud differentiation requirements of day and night temperature of about 20 ℃ and 10 ℃, respectively, the root growth of the soil temperature is roughly the same as the ground. High temperatures are also detrimental to the growth and development of citrus, air temperature, soil temperature higher than 37 ℃ when the fruit and root system stop growing.

2, light: oranges are shade-tolerant species, but to quality and yield still need good sunshine. General annual sunshine hours of 1200 to 2200 hours of the region can grow normally. Such as good sunshine, heat-rich South China and less sunshine compared to Chongqing citrus production areas, fruit sugar content, acid content is low, sugar-acid ratio is high.

3, humidity: oranges in the annual rainfall of about 1,000 millimeters of tropical and subtropical regions are suitable for planting, the relative moisture content of the soil to 60 to 80% is appropriate, less than 60% is required to irrigation, too much rain caused by soil water or high water table, in poor drainage citrus orchards will make the root system die.

4, soil: orange on the soil to adapt to a wide range of purple soil, red and yellow loam, beach and sea, ph value of 4.5 ~ 8 can grow to ph value of 5.5 ~ 6.5 for the most suitable. Root growth requires high oxygen content, with loose soil texture, good structure, organic matter content of 2 to 3%, well-drained soil is most suitable.

Oranges sketch:

Oranges shape outline: draw a round orange shape on the paper, the top end of the orange can be drawn more pointed. Then paint the orange in orange color.

The wrinkles at the top of the orange: draw the wrinkled outline of the orange at the top of the orange.

Petiole of the orange: at the top of the orange, draw the petiole of the orange. Paint the drawn petiole a dark or dark green color.

The leaves of the orange: at the top of the petiole of the orange, draw the leaves of the orange and finally paint the leaves of the orange green.

On the other side of the petiole, draw the other leaf of the orange. Because of the side view, the leaf on the left side can be smaller and then painted green.
