Irrigation Scheme Selection Based on Water Footprint Analysis of Winter Wheat Production in Piedmont Plains of Hebei Province under Future Climate Scenarios

The statistical downscaling tool of a model (SDSM) to generate the future climate piedmont plain area in Hebei Province for 30-year period. Xinji city was selected as typical example this area. crop growth decision support system agrotechnology transfer (DSSAT) adopted estimate changing trends water footprint winter wheat production under conditions, and obtain optimal irrigation scheme an ‘acceptable yield’. According test results, all temperature indices increased two scenarios. In addition, effective precipitation exhibited slight decrease scenario A2 remarkable increase B2. Both total green increased. A yield 500 kg per mu taken acceptable yield. A2, achieve yield, it required irrigate once jointing period with rate 105 mm. B2, one-time amount 85 mm sufficient reach
