Abstract:

In the scenario that water shortage has become a critical factor impacting world economy, and two thirds of the available water are being used for agriculture, it is crucially important to adopt water-saving agricultural technology in order to use the water more efficiently to produce more farm products with limited resource under the greater pressure for agricultural production increase and of less available water resource. This article reviewed the international advances in agricultural water use in the aspects of management means, engineering technology, agronomic measures and biological methods as well as utilization of low-quality water, recycled water and rainfall. Based on the review of the successful experiences and the current status of water resources, approaches for water-efficient and highly productive crop production in Hebei plain were proposed.
