Yu Cheng Integrated Agricultural Experimental Station
The station (116°6'E, 36°7'N) is located at the southwest of Yu Cheng County in Shandong Province with an altitude of 20 meters above sea level. The area lies in the semi-humid, temperate and monsoon climate zone.. The annual temperature averages 21°C and the annual precipitation is 610mm. The under ground soils of the area are mainly the moisture soil and the salinized moisture soil. The natural conditions and agricultural production level of the area around the station are typical to the Huang-Huai-Hai Plain. The construction of the station was started in 1979 and completed in 1983. It was ratified as an opening station by CAS in 1987 and incorporated into CERN in 1992.
The research work of the station focuses on the study of the structures and functions of agro-ecosystem, especially the energy transfer and material movement regarding the movement and utilization of water, as well as the optimization and management of agro-ecosystem, aimed mainly to serve the rational utilization of agricultural resources including water, soil, climate and biological resource etc., the comprehensive harnessing of such inhibiting factors as drought, water logging, and salinization etc., and the sustainable development of agricultural production.
Items of long term observation of the station include:(1) Farmland water evaporation; (2) Water demand ，water consumption, water utilization rate, and the rational use of ground water; (3) Farmland water observation; (4) Observation of the gradients of temperature, humidity, and wind regarding to the interaction of ground and atmosphere; (5) Iron tower experimental remote sensing system; (6) Crops photosynthesis.
