| Abstract: | Drought has become a global question. It is also the obstacle that baffles the food yield in arid region of China. The selfpropelled water-saving irrigation technology offers the potent guarantee for the food production in arid region. This paper detailedly introduced the origin, theory basis, water-saving principle, work content and machine classification of the technology. Moreover, the social and economic benefit of the technology was expounded, too. |
