The southern region is superior to the northern region in terms of heat and moisture conditions. Its favorable conditions for agricultural production include:

①Rain and heat are in the same period, and water and heat are well coordinated;

② The plains of the middle and lower reaches of the Yangtze River and the Pearl River Delta have low terrain, fertile soil, and crisscross river branches, which are convenient for irrigation and conducive to the development of freshwater aquaculture; the Sichuan Basin has fertile purple soil; the Hengduan Mountains have rich forest resources, many tree species, and little human influence, which is conducive to Develop forestry production.

③The Yangtze River Basin has a long history of agricultural production and high production levels

Therefore, the southern region has developed a planting industry based on paddy fields in plains, basins and other areas, and crops can be harvested two to three times a year; low mountain and hilly areas are important forest areas in southern my country, where evergreen broad-leaved forests grow; the Pearl River Base pond production in the delta: mixed agriculture; Guangdong and Guangxi are the main producing areas of tropical and subtropical fruits in my country, rich in bananas, pineapples, lychees, etc.; Hainan Island, Leizhou Peninsula and the southern part of Taiwan Island are the production bases of tropical cash crops in my country, such as natural rubber.
