Paper Abstract

In line with the equation of soil moisture balance and the results from field experiments for years, the source and consumption of soil water components and their calculating models were scientifically analyzed. And based on the wheat condition in its whole growth and development period, as well as water consumption pattern and soil water stress index, a computer-based comprehensive study was made for discussing spatial distribution of non-stress soil water content, field moisture utilization and irrigation mode for winter wheat in different climate years to provide useful suggestion as to directing irrigation and management. The analysis showed that: no matter under what type of climatic conditions, winter wheat fields need irrigation at least once in northern part of Henan Province, however, in southern part, especially the southern area of Huai River, irrigation is needless; cornfields in the middle of the province should be irrigated once in the years short of precipitation, while not be irrigated in the years with abundant rainfall.
