Abstract

Using the winter wheat in North China as research object, AquaCrop model was applied in different technology of irrigation, included drip irrigation, sprinkler irriga tion and furrow irrigation. Thema in parameters like soil and crop characteristics and soon, were ad justed. In addition, the effective simulation method for crop yield and biomass was researched. The study showed that some simulated values like yield and biomass of soil were significative. The relative error ( RE ) was low. Simulated data was a little higher than the observed one. All of the modeling efficiency ( EF) was more than 0. 95. The modeling was better for yield than that for biomass. The modeling was also the most efficient for drip irrigation in the three kind of irrigation technology.
