Citrus, as the leading industry of characteristic agriculture in Zhongxian County, has formed a complete industrial chain of production, marketing and research, which has not only brought Jinshan Yinshan, but also contributed to a citrus ecological corridor on both sides of the Yangtze River and embarked on a green development road.
In friendship village, Tujing Township, Zhongxian County, the original ecological beauty of the Orange Sea and the scenery of the Three Gorges complement each other, and numerous fruits and beautiful mountains and rivers set each other off, depicting a picture of a paradise and a classical village.

Citrus fruit trees bring the vast scenery of the orange sea, and also bring visible income to fruit farmers.
Growing environment of citrus:
The growth, development, flowering and fruiting of citrus fruit trees are closely related to environmental conditions such as temperature, sunshine, moisture, soil, wind, altitude, topography and slope direction, which have the greatest influence on temperature. Even if the temperature difference is 0.5℃, sometimes there will be completely different results. The growth and development of citrus need a temperature of 12.5-37℃.
The day and night temperatures of flower bud differentiation in autumn are about 20℃ and 65438 00℃, respectively, and the soil temperature of root growth is roughly the same as the ground temperature. If the temperature is too low, oranges will be frozen. When the sweet orange is at -4℃ and the satsuma orange is at -5℃, the branches and leaves will be frozen. When the sweet orange is below -5℃ and the satsuma orange is below -6℃, the plants will freeze to death.
