Abstract

Four agrometeorological sites located in wheat production areas, Harbin, Jinan, Zhengzhou and Chengdu were chosen to study the impact on wheat biomass with rise of temperature and CO2 concentration in many scenarios with the help of the process mechanism model in the probabilistic forecasting method. The results show that the CO2 fertilization effect can compensate reduction of wheat biomass with warming temperature in a strong compensating effect. Under the CO2 fertilization effect, the rain-fed and irrigated wheat biomasses increase respectively, and the increment of biomass goes up with temperature rising. The rain-fed wheat biomass increase is greater than the irrigated wheat biomass. Without consideration of CO2 fertilization effect, both irrigated and rain-fed wheat biomasses reduce, and there is a higher probability for the irrigated wheat biomass than that Of thu ain-fed wheat biomass
