1概述传统的农业灌溉一般采用地面灌水方式，如畦灌、沟灌、淹灌等，灌溉水由灌区内的各级渠道来分配。随着农业生产的发展和人口的不断增长，水资源日益紧张，农业灌溉正在逐步推广新型的节水灌溉技术，如喷灌、微喷灌、滴灌、管道输水灌溉等，这些新型灌水技术具有增产、节水 1 Overview Conventional agricultural irrigation generally uses surface irrigation methods, such as irrigation, furrow irrigation, flooding irrigation and so on. The irrigation water is distributed by various channels in the irrigation area. With the development of agricultural production and population growth, water resources are increasingly tense, and agricultural irrigation is gradually promoting new water-saving irrigation technologies such as sprinkler irrigation, micro-irrigation, drip irrigation and pipeline irrigation. These new irrigation technologies have the advantages of yield increase, Save water
