小麦区域试验边际效应的研究

Research on the marginal effect of wheat experimental plot

对小麦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,获得评估小区边际效应的模拟曲线方程,根据方程对整个小区的边际效应进行评估.结果表明,小麦区域试验边际效应在实际产量中所占的份额为7.41%～27.08%,平均为14.95%,这远远大于审定一个新品种的要求 比对照产量增产5% .所以边际效应的存在将直接影响各个材料产量的高低及名次的排列,影响到材料的审定及在生产上的利用价值.

Corresponding relationship between yield and rows in the wheat experimental plot has been simulated in this research, and the function of simulated curve has been obtained. Marginal effect can be evaluated by the function. The accuracy of experimental results will be greatly increased if this method can be adopted. The result of research show that marginal effect of wheat cultivar zero test account for 7.41～(27.08) percent in the fact product. It surpass significantly over the clemanel for new variety that yield must increase more that 5 percent compare to the ck. Consequently marginal effect influence directly on the yield、order、protective value and cultivar registration.
