CO2 concentration and relevant temperature increases and rice yield-A case modeling study in Zhejiang Province

Abstract

Abstract: Acomprehensive process-band model ORYZA1 was used to simulate the impact of 15 cases ofprobable climate changes on rice yield in Zhejiang Province. Thc results show that CO₂ concentration increase could result in the grain yield increase, whereas the rdevant temperature increase could decrease it. The impact of CO₂ concentration and relevant temperature increases onrice yield varies among regions. However, when the changes in rainfall and crop pest status areneglected, the annual rice yield could increase by 9. 53, 8. 92 and 0. 04 % under the climatechanges predicted by GFDL, GISSand UKMOmodels, respecitively.

Key words: CO₂, Temperature, Rice yield, Modeling, Panax notoginseng, non-photochemical quenching, photosynthesis, light intensity, photosynthetic induction
