Research Conditions

 

        The team's scientific research work is mainly carried out relying on the Key Laboratory of Crop Water Requirement and Regulation of MOA, Xinxiang Qiliying Comprehensive Experiment Base of FIRI, and the field test bases jointly constructed in Alar Xinjiang, Jiaozuo Henan, Xuchang Henan and other places. The laboratory has a flow analyzer, liquid chromatograph, gas chromatograph, isotope ratio mass spectrometer, multi-gas analyzer, photosynthesis measurement system, soil respiration measurement system, root ecological monitoring system, walk-in phytotron, Kjeldahl apparatus, eddy covariance system and other equipment, as well as crop water requirement test field, weighing lysimeter and non-weighing lysimeter group, intelligent environmental control phytotron, solar greenhouse group, barrel planting and potted planting areas and other large-scale experimental facilities, which provide good conditions for scientific and technological innovation in theories and new technologies of deficit irrigation.

 

 

Scientific Research Projects

 

        During the “Thirteenth Five-Year Plan”, the team members have presided over more than 20 projects including Special Projects for Public Welfare Industries (Agriculture), special projects for post scientists in the Industrial Technology System of MOA, National Key R&D Plan, and Natural Science Foundations. The annual research funding is more than 3 million yuan.

 

 

Achievements

 

        In the past 3 years, the team has won 3 scientific and technological awards at or above the provincial and ministerial level, obtained 8 software copyrights and published more than 70 papers in Field Crops Research, Agricultural Water Management, Irrigation Science, Environmental Science and Pollution Research, Acta Ecologica Sinica, Transactions of the Chinese Society of Agricultural Engineering, Chinese Journal of Applied Ecology and other domestic and foreign core journals and above, of which 27 are included in SCI. The team has cultivated more than 16 doctoral and graduate students.

 

 

Research Direction

 

Research direction 1: Crop-water relationship and deficit irrigation theory

Leader Meng Zhaojiang  Member Shen Xiaojun, Niu Xiaoli, Zhang Yingying

The Irrigation Experimental Station of the Ministry of Water Resources

 

        The Irrigation Experimental Station of the Ministry of Water Resources was established in April 2003, which is an important component of China's three-level irrigation experimental station network system. It is mainly responsible for the cooperation project of the Department of Rural Water and Hydropower of the Ministry of Water Resources, assists the Ministry of Water Resources to complete the construction plan of the national irrigation test station network, arrangement of irrigation test tasks, organization of professional training for the national irrigation test station network, and the establishment of basic data database for the national irrigation test station network. Since 2003, 15 irrigation test network technical training courses have been held to train 680 backbones of 165 irrigation test stations in various provinces and cities. In recent years, the station has assisted the Ministry of Water Resources to complete the survey of instrument standards for the national irrigation test station network, and formulated the “National Irrigation Test Station Network Management Measures”. In 2015, the station assisted the Ministry of Water Resources to compile the “National Irrigation Test Station Network Construction Plan”. In 2016, the Irrigation Test Center was established to take charge of the daily operations of the Irrigation Experimental Station of the Ministry of Water Resources.
