Pictures and sketches of where oranges grow are as follows: Where they grow: Oranges in my country are distributed between 16 and 37 degrees north latitude, with an altitude of up to 2,600 meters (Batang, Sichuan), starting from Sanya City in Hainan Province in the south to Shaanxi and Gansu in the north. , Henan, starting from Taiwan Province in the east and reaching the Yarlung Zangbo River Valley in Tibet in the west.

However, the economic cultivation areas of citrus in my country are mainly concentrated between 20 and 33 degrees north latitude, at an altitude of 700 to 1,000 meters below sea level.

There are 19 provinces (municipalities and autonomous regions) producing citrus in the country, including Taiwan Province. Among them, 10 provinces (including Zhejiang, Fujian, Hunan, Sichuan, Guangxi, Hubei, Guangdong, Jiangxi, Chongqing and Taiwan) mainly produce citrus (

cities and districts), followed by Shanghai, Guizhou, Yunnan, Jiangsu and other provinces (cities), and also planted in Shaanxi, Henan, Hainan, Anhui and Gansu provinces. There are 985 counties (cities and districts) where citrus is grown across the country.

World distribution of oranges: Oranges in the world are mainly distributed in the area south of 35° north latitude. They like warm and humid nature. Areas with large water bodies that heat up can push north to 45° north latitude.

There are 135 countries in the world that produce citrus, with an annual output of 102.822 million tons and an area of ??107.3 million acres, ranking first among all fruits. Brazil ranks first in production with 24.2526 million tons, and the United States ranks second with 16.3352 million tons.

, China is third with 10.78 million tons, followed by Mexico, Spain, Iran, India, Italy and other countries.

The production environment of oranges: 1. Temperature: The growth and development of orange fruit requires a temperature of 12.5 to 37°C. The differentiation of flower buds in autumn requires day and night temperatures of about 20°C and 10°C respectively. The soil temperature for root growth is roughly the same as that of the above ground.

High temperature is also not conducive to the growth and development of citrus. Fruits and roots stop growing when the air temperature and soil temperature are higher than 37°C.

2. Light: Orange is a tree species with strong shade tolerance, but it still needs good sunshine to achieve high quality and high yield.

Generally, areas with annual sunshine hours of 1200 to 2200 hours can grow normally.

For example, compared with the citrus-producing areas of Chongqing, which has less sunshine and less sunshine, South China, which has good sunshine and rich calories, has higher fruit sugar content, lower acid content and higher sugar-acid ratio.

3. Humidity: Oranges are suitable for planting in tropical and subtropical areas with annual rainfall of about 1,000 mm. The relative moisture content of the soil is 60 to 80%. If it is less than 60%, irrigation is required. Too much rain will cause water accumulation in the soil or

High water tables can kill roots in poorly drained citrus orchards.

4. Soil: Oranges have a wide range of adaptability to soil. They can grow in purple soil, red and yellow soil, beaches and tidal flats with a pH value of 4.5 to 8, with a pH value of 5.5 to 6.5 being the most suitable.

Root growth requires high oxygen content, and soil with loose texture, good structure, 2 to 3% organic matter content, and good drainage is most suitable.

Simple drawing of an orange: Shape outline of an orange: Draw a round orange shape on the paper. The upper end of the orange can be made more pointed.

Then paint the orange orange.

Wrinkles on the top of the orange: Draw the outline of the wrinkles on the top of the orange.

Orange petiole: At the top of the orange, draw the orange petiole.

Paint the drawn petiole dark green or dark green.

Orange leaves: On the top of the orange petiole, draw the orange leaves, and finally paint the orange leaves green.

On the other side of the petiole, draw another leaf of the orange.

Because of the side view, the leaves on the left can be smaller and then painted green.
