Jiansanjiang is an administrative area of 230,000 in eastern Heilongjiang province, China. It was established as a nongken farm.
Being a former agricultural reclamation land, Jiansanjiang has a rich history of agriculture, and is known for having areas of chernozemic soil.[2] The city is discussed in detail in academic papers on Agriculture in China: notably China Agricultural University has an experimental station looking at rice varieties in the city.[3]
Jiansanjiang is known as China's green rice city,[4] and its Honghe farm was the first modernised farm in the whole of China, making use of agricultural drones and other technologies.[5]
Jiansanjiang Shidi Airport was opened in October 2017.[6] By road, Jiansanjiang connects to the G1011 via the S11 Jianji Expressway.
Jiansanjiang also connects to Harbin (via Jiamusi) and Fuyuan by rail.
The asteroid 207723 Jiansanjiang is named after the city.
