摘要： 在灌溉农业中，人们通过改造梯田、条田进行灌溉；这种灌溉方法，起到了保水、保肥、保土的作用，确保了农作物稳产高产。但这种灌溉方法同时也带来不少问题。为了克服这些问题和不足，经理论研究和实验证明，在甘肃省河西走廊缓坡地带实施纵向微水自流灌溉是一种可行的方法。

Abstract: In irrigated agriculture, people irrigate through the transformation of terraces and strip land; this irrigation methods are with function of water preservation, fertilizer, soil conservation role in ensuring that the high-yield crops. However, this irrigate method also brings many problems. To overcome these problems and shortcomings, through theoretical research and experiment proved, gentle slope zone in the Hexi Corridor in Gan su Province, longitudinal micro-water gravity irrigation is feasible.
