Chinaagrosys
WebIrrigation plays an important role in crop yield production in arid and semi-arid regions. However, irrigation effects have not been well addressed in the application of crop models at a regional scale due to limited data availability, which constrains the reliability and accuracy of simulation results. WebA schematic depiction of ChinaAgrosys crop and microclimate. The soil module includes the heat transfer, water movement and root water uptake. The crop module includes submodels of photosynthesis and respiration, stomatal conductance, dry-matter partition, LAI and development.
