Abstract

Abstract: 【Objective】To reveal the current situation and water-saving potential of main crops irrigation in Hetao Irrigated Area and put forward optimization suggestions.【Methods】The irrigation situation was analyzed by using the survey data and literature data of 310 households in Hanggin Rear Banner.【Results】In this region, wheat, corn and sunflower were irrigated for many times with high irrigation quota, and the average crop irrigation water productivity was only 1.43 kg/m³.By adopting water-saving planting technology and scientific irrigated in Autumn, the three main crops could save 200 million-315 million m³ water per year.【Conclusion】Since the irrigation behavior and low water resource utilization efficiency in Hetao irrigated area, large water-saving space can be ture by combining the border irrigation and high efficient water-saving irrigation.

Key words: Hetao Irrigation Area, Irrigation status, Water-saving potential, Irrigation suggestions
