Abstract

This paper took the northwest of Liaoning Province as a study area and maize as the research object. Effective rainfall, crop water requirement and soil available water content at 6 growth stages of maize were calculated by using Penman-Montes equation, effective coefficient method and Cropland Soil Moisture Index. Then the estimation model of irrigation water requirement of maize at different growth stages of the northwest of Liaoning Province. Taking 2006 as an example, the irrigation water requirement of maize at different growth stages was estimated and the spatial distribution maps were drawn by GIS. The results show that overall the irrigation water requirement of maize in the western of the study area is more than that of in the northeastern. The irrigation water requirement of maize in heading stage has increased significantly because of the severe drought status. it can provide technical support for a region to relieve crop drought.
