近年来,随着我国水资源紧缺现状的日益加剧,国家加大了对农业生产结构的调整,特别是对水利建设投入不断增加,促进了农业生产的环境的不断改善。然而,工业等用水量随着我国经济高速发展不断增加,工业用水与农业用水形成了深刻的矛盾关系,加之农作物需水量增加、农业有效用水率低、水资源污染等问题突出,农业生产用水亟需进一步优化配置,以提高对现有可用水资源的高效利用。为此,应更新观念,研究现代农业用水发展现状和发展趋势,以利于其又快又好地发展。
In recent years, with the increasing shortage of water resources in our country, the state has stepped up the readjustment of the structure of agricultural production. In particular, investment in water conservancy has been steadily increasing, which has contributed to the continuous improvement of the agricultural production environment. However, with the rapid economic development of our country, industrial water consumption has formed a profound contradiction with the demand for water for agriculture. Coupled with the increase in crop water requirements, the problems of low water use efficiency and water pollution in agriculture, Further optimization of the configuration is needed to improve the efficient use of available water resources. To this end, we should update our concept and study the status quo and development trend of modern agricultural water use in order to facilitate its rapid and good development.
