摘　　要：开展农田灌溉水有效利用系数测算和主要作物需水量试验工作,是贯彻落实最严格水资源管理制度的实际需要,也是灌溉系统规划、农村水利工程设计的迫切要求。本文以普洱市为例,依据《灌溉水利用率测定技术导则》和《灌溉试验规范》的相关技术规定,收集了全市灌区资料并选址查勘,选定了样点灌区和典型田块,制定了合理可行的农田灌溉水有效利用系数测算和主要作物需水量试验实施方案。同时,项目的实施将填补普洱市农田灌溉水有效利用系数和主要作物需水量的空白,为推动农业节水管理提供科学依据,对提高普洱市农田灌溉用水效率、促进全市高原特色现代化农业发展具有重要意义。本项目的实施以期望为类似工程的设计与实施提供一些有益的参考。The calculation of irrigation water effective use efficiency and main crop water demand are the practical needs of the implementation of the most stringent water resources management system. It is also an urgent requirement for irrigation system planning and rural water conservancy project designing. Based on the ＂irrigation water utilization technology guidelines＂ and ＂irrigation test specifications＂, the relevant technical requirements, the city＇s irrigation data and site were collected and surveyed; sample irrigation and typical plots were also selected. The effective calculation of the effective utilization coefficient of irrigation water and the implementation plan of the main crop water demand test were conducted. At the same time, the implementation of the project will fill the effective utilization coefficient of irrigation water and the main crop water demand in the Pu＇er City, and provide scientific basis for promoting agricultural water saving management to improve the efficiency of irrigation water significance. The implementation of this project is expected to provide some useful reference for the design and implementation of similar projects.
