摘要
运用积分回归、正交多项式等方法分析豫东地区冬小麦产量与旬降水量的关系，筛选出影响冬小麦产量的关键降水时段，并对这一地区冬小麦生产中的水分管理提出一些意见和建议．
The eastern Henan is the most improtant base of commodity grain in the province.With the integral regression and the orthogonal polynomial method,this essay analyzed the relations between output of the fall wheat and the ten day precipitation in eastern Henan,decided the main period of the rainfall which affect the output of the fall wheat and gave some advice on how to manage the water for the eastern Henans fall wheat growing.
