我国是一个水缺乏的国家。长期面临着用水短缺的制约,是我国北方干旱地区农业生产的一个显著的特征。干旱的连年发生,给农业生产和群众生活造成了严重影响。对于这样的农业大国,理所当然是用水大户。而且我国水资源利用率较低,有很大的节水开发潜力。如何使有限的水资源得到有效利用,用来提高农业生产的利用率,来满足生产较多的粮食、蔬菜和水果等农产品,大力推广农业节水增效灌溉技术是缓解水资源紧缺的根本出路,更是是提高农业综合生产能力,确保农业可持续发展的必然
Our country is a water-scarce country. Long-term face of water shortage constraints, is a prominent feature of agricultural production in arid areas of northern China. Drought year after year has seriously affected agricultural production and people’s livelihood. For such a big agricultural country, of course, is a big water user. Moreover, the utilization rate of water resources in our country is relatively low, which has great potential for water saving development. How to make effective use of limited water resources, to improve the utilization of agricultural production, to meet the production of more food, vegetables and fruits and other agricultural products, and vigorously promote agricultural water conservation irrigation technology is to alleviate the fundamental shortage of water resources , But also is necessary to improve the comprehensive agricultural production capacity and ensure the sustainable development of agriculture
