摘要
Abstract
Based on the field measured data of wheat intercropping maize in comprehensive agricultural water saving demonstration area in Hetao district,the reference crop evapotranspiration of interplanted crop was computed according to the Penman-Monteith method.Considering the characteristics of interplanting,the comprehensive crop coefficient was settled.Meanwhile,the irrigation system of wheat intercropping maize was evaluated by WIN ISAREG model,The deep seepage quantity was 2.67%,irrigation efficiency was 99.42%,and the yield by rate was 11.50% of test MY2 in the whole growth stage,it was better than other tests but still need to optimization.According to crop having different water demand in different period,we can use ISAREG model to simulate and optimize irrigation system,and got optimization irrigation system that was irrigated 5 times in the whole stages,irrigation time respectively were May 10,May 24,June 17,July 10 and July 30,and irrigation quota respectively were 75 mm,80 mm,90 mm,90 mm and 80 mm.The results can provide the technical support for water saving and optimization management of Hetao irrigation District.关键词
