Water Use Features of Typical Crops and Technical Modes of Modern Agriculture Irrigation in China
A survey of field crop water use features, agricultural irrigation technical modes, and modern agriculture irrigation systems is of instrumental and practical value to improve agricultural water use efficiency and achieve sustainable utilization of agricultural water resources. This paper analyzes the irrigation schedules of typical crops, covering in particular the Huanghuaihai Plains (the Yellow River, the Huai River, and the Hai River) wheat belt, the Northeast rice belt, the rice belt in middle and lower reaches of the Yangtze River, the Sichuan Basin rice belt, the eastern Inner Mongolia pasture, the Guangxi sugar cane belt, and the Xinjiang cotton belt, all classified according to the Chinese comprehensive agriculture zonation, and arrives at some optimal technology modes. Meanwhile, the technical features of modern agricultural irrigation are summarized and a policy assurance system for it is proposed. The main conclusions are as follows: ① Applying optimized irrigation program to major crops in each comprehensive agricultural zone not only ensures water supply in the sensitive water shortage period, but also saves irrigation water, stabilizes yields, and improves water productivity; ② In view of the characteristics and restraints in each zone, advanced water-saving technology modes are recommended and promoted, which supports the precision implementation of the optimized irrigation program and improves the comprehensive production capacity of regional agriculture; ③ To match and support the modern agricultural production and management system, an IT-based modern irrigation technology and its corresponding financing mechanism and water rights management mechanism, among other policy assurance systems, are proposed.
