The diagnosis and estimation of CO₂ concentration increasing and climate warming on the agricultural production

The crop growth and development，as well as the outputs for cereal crops(wheat，rice，maize，and soybean)，vegetables(Chinese cabbage，cucumber)under CO₂ concentration increasing are studied through simulation experiment，and the effects of climatic warming on agricultural technologies and agricultural climate are analyzed． Finally，the agricultural diagnosis is made and some countermeasures are put forward．
