摘要
选择了新疆冬小麦生产中对产量影响最大而又容易控制的５个因子，采用５因素５水平通用旋转组合设计，研究了播种粒数、底肥纯氮量、底肥纯磷量、返青后追氮时间和追氮量等单因素效应和因素之间交互效应对籽粒产量的影响。利用回归模型，频数分析和计算机模拟等方法。
The single effect and alternate effect of sowing norm, basement N,basement P and time and amount applying N after turn green to kernel yield by a universal revolve regression disign with 5 fators and 5 levels.These factors are the most improtant and control easyly in winter wheat production in Xinjiang.An optimun culture measure of 5 626～6 375 kg per hectare was optimized by regression matix,freqence analysis and computor simulate and etc.
