为了探析温度变化对不同耕作措施春小麦产量的影响，利用 APSIM 模型对2因素9水平3种耕作措施下的春小麦产量进行了模拟，选择日最低温度和最高温度作为自变量因子对产量效应进行分析，并对3种耕作措施条件下最低温度和最高温度的互作效应进行通径分析。结果表明：不同耕作措施条件下，春小麦产量随最低温度升高呈二次抛物线上升型变化，会出现报酬递减，且传统耕作＋秸秆还田和免耕覆盖的增产效应大于免耕耕作措施；传统耕作＋秸秆还田和免耕耕作措施下，产量随最高温度升高呈二次抛物线递减型，并呈叠加递减，而免耕覆盖耕作措施下产量随最高温度升高呈负相关。3种耕作措施下，最低温度和最高温度之间还存在正的协同效应，免耕覆盖耕作措施相比其它两种耕作措施，具有更好的协同促进效应。

In order to analyze the influence of the temperature variationson the yield of spring wheat with different cultivation measures ,the spring wheat yields resulted from cultivation measuresemploying two-factor ,nine-level and three-typewere simulated by the APSIM model .Yielding-effect was analyzed by choosing the lowest and the highest day temperatures as the independent variable factors .Interacting effectsbetweenthe lowest and the highest temperatures under three kinds of tillage measures were also investigated by a path analysis .It turned out that under the conditions of differ-ent tillage measureswith the increase of the lowest temperature ,the yield of spring wheat changed in a quadratic parabola rising pattern ,displayinga decrease inrewards .The cultivation measure using conventional tillage ,straw returning and no-tillage with mulch played a more important role in yield improvement than no-tillage cultivation .Under the condition of traditional tillage ,straw returning and no-till farming measures ,the yield decreased in a quadratic parabola type ashigh-est temperature rose ,showinga superposition of diminishing .Yield was negatively correlated with the highest temperature while the production was under covered no-till farming measures .Withinthe three kinds of cultivation measures ,there was a positive synergy between the lowest temperature and highest temperature ,and cultivation measure usingno-tillage with mulch had a better synergistic promoting effect than the other two kinds .
