图5. 夏玉米不同品种参数组合获得产量与基准品种可获得产量差值
产量差值=不同出苗到拔节期积温和开花到成熟积温组合获得产量-基准品种获得产量。（a）、（b）、（c）、（d）分别代表鲁东、鲁中、鲁西北、鲁西南
Fig. 5. The gap between the yield of summer maize from different varieties and the yield of standard varieties
Yield gap = yield available by different combinations of tt_emerg_to_endjuv and tt_flower_to_maturity - yield available by standard varieties. (a), (b), (c), (d) represent ES, CS, NS, SS, respectively
