摘　　要：本文对玉米品种试验小区各行实际产量与行的对应关系进行曲线拟合 ,从而获得可用来评估小区边际效应的模拟曲线方程 ,根据方程提供的参数 δ对小区边际效应进行评估。将此方法用于产量潜力评估 ,可极大地提高试验结果的准确性。Corresponding relationship between yields and row No. in the corn experimental plot has been simulated in this research,and the function of simulated curve has been obtained.Marginal effect can be evaluated with reference to the parameter δ provided by the function.The accuracy of experimental results will be greatly increased if this parameter can be used in various yield-experiments.
