Subsurface Drip Irrigation System in Agriculture

美国用地下渗灌方法进行农业灌溉,已有20多年的历史,取得了很多成功的经验,本文主要介绍美国这项研究的历史,发展现状和用此法进行农业灌溉的具体管理方法。建议在我国进一步加强这方面的研究,为大面积普及此灌溉方法作准备。

Subsurface drip irrigation (SDI) system was applied to practice in agricultural irrigation successfully in USA from early 1970's. This paper introduced the researches on this area about its development, current status, and the main ways to manage a SDI system for growing crops in USA. The paper believed that further researches needed to be conducted on this area in China in order to meet the needs in the future when SDI system will irrigate large agriculture field.
