采用二因素二次饱和 D—最优设计 ,应用计算机处理试验数据 ,对春小麦生产中播种密度和第一次灌水叶龄两项主效农艺措施组合进行降维求优 ,提出具体的量化指标
Two-factor secondary saturating D-optimal design was adopted. The experimental data of computer processing were used to reduce the dimension of the two main agronomic measures in sowing density and the first leaf age in spring wheat, and the specific quantitative indexes
