The case is launched by a team jointly composed of Scholl of Geography and Remote Sensing of Guangzhou University，Guangzhou Conghua District Agriculture and Rural Bureau，Guangzhou Conghua Hualong Fruit and Vegetable Preservation Co.，Ltd. The case has been listed as a case of the "Geographical Indications Environment & Sustainability " (Case 8).

The case area of Jiangpu in Conghua is located in the eastern part of Conghua District in the central Guangdong region of Guangzhou, with longitude 113 º 17 ′ -114 º 04 ′ E and latitude 23 º 22 ′ -23 º 56 ′ N. The area is 131 km2. Belonging to the transitional zone between central subtropical and southern subtropical regions, the climate type is subtropical monsoon climate. The average precipitation from 2000 to 2020 was 1992.7 mm, the annual average temperature was 21.5 ℃, and the annual average sunshine time was 1588.1 hours.

Rich in light, heat, and water resources, it is suitable for the growth and development of lychee. Conghua is connected to the mountains in northern Guangdong in the north and the the Pearl River Delta Plain in the south, which is the middle zone of the transition from mountains to plains. The main soil types in Jiangpu are lateritic red soil, which is conducive to organic matter accumulation and is slightly acidic, as well as tidal soil formed by river and groundwater movement, both of which are suitable for planting lychees.

Lychee belongs to the Sapindaceae family and the lychee genus is an evergreen tree. Jinggang Hongnuo is an excellent new variety of lychee selected by the School of Horticulture of South China Agricultural University from excellent individual lychee plants. This variety is resistant to cracking fruit, lychee downy mildew, thick flesh, round crown, vigorous tree vigor, with an average length of 8.98 cm and a width of 3.11 cm on leaves, and a petiole length of 0.62 cm. The main vein is obvious, and the lateral veins are not obvious. The leaf edges are microwave shaped, and the leaves are green. The leaf shape is similar to "Nuomici".

Guangzhou Conghua Hualong Fruit and Vegetable Preservation Co.，Ltd was established in 1998 and is a key agricultural leading enterprise in Guangdong Province, a leading agricultural enterprise in Guangzhou City, a national high-tech enterprise, a new research and development institution in Guangzhou City, and a "two high and four new" demonstration enterprise. Its output value is over 80 million yuan, and it deeply cultivates the lychee planting industry, driving more than 3000 households. It mainly exports to European and American markets and supplies domestic supermarkets. The company has a standardized production base of 3500 acres, including lychees, and has obtained certification for export registration and green food production base. The cooperative base covers more than 8000 acres. Under the guidance and guidance of the Conghua government and the Conghua Agriculture and Rural Bureau, Hualong, a lychee management enterprise in Conghua, has made years of efforts to establish a mature industrial model. As of 2021, the annual production of lychee in the entire region of Conghua is 65000 tons, with a total output value of 2 billion yuan.

In order to better monitor and manage the habitat of lychee, in June 2020, the Conghua Government and the Guangdong Provincial Department of Agriculture joined forces with Guangzhou Conghua Hualong Fruit and Vegetable Preservation Co.，Ltd to apply technologies such as 5G, Internet of Things, big data, artificial intelligence, cloud computing, and drones to build a 5G+intelligent lychee orchard. The Internet of Things technology was used to achieve intelligent water and fertilizer integration, achieve digital lychee planting, scientific management, research and application of hilly and mountainous orchard mechanization, improve the automation of orchard production, and achieve precise management of lychee intelligent orchards that improve efficiency, reduce costs, and enhance experience.

Conghua is a famous "hometown of lychees" in China, with records of lychee cultivation dating back over 200 years. Before the founding of the People's Republic of China, Conghua had over 10000 acres of lychee planting area, which was an important source of income for local farmers. After decades of tepid development, the country began to shift its focus to economic development in 1978, vigorously developing the lychee planting industry in Conghua. By 1981, the planting area had grown to 24100 acres, ranking among the seven key lychee counties in China. The development boom, mainly focused on cultivating lychees in the mountains, has rapidly risen. By 1996, the planting area of lychee in the entire region had increased to 109000 acres, and the Ministry of Agriculture, Animal Husbandry and Fisheries of the State Council approved Conghua as a lychee production base city (county). From then on, lychee production has developed towards scale, industrialization, and standardization.
