THE IMPACTS OF CLIMATIC CHANGE ON PRODUCTION OF DROUGHT LAND CROPS

Gao Suhua;Guo Jianping;Wang Chunyi(Chinese Academy of Meteorological Sciences,Beijing 100081)  
Through the artificial simulation experiments and field trails for the impacts of CO_2concentration on growth、development and yield of drought land crops,the results showthat:(1)the high CO_2 concentration would speed up the crop development course ,it isfavourable to dry matter accumulation and grain yield increasing;(2)the temperaturerise would shorten the development duration of drought land crops ,and in a certainrange,it shows a positive effect on grain yield;(3)if the temperature rise range exceeds2℃, the grain yield of spring wheat would decrease even if the CO_2 concentration isdoubling, It is because CO_2 concentration rise is not favourable to grain protein andamino acid formation。
