摘要
以云南省陆良县大莫古３３３３ｈｍ２提灌工程设计中作物灌溉定额的确定为例，利用彭曼公式和计算机分析技术，计算出滇中红壤区几类主要作物的需水量、最佳耗水量和最佳经济灌溉定额。同时根据气候特点、作物生理特性及耗水规律确定灌溉定额分配及灌溉时机。为灌溉工程设计提供了可靠的科学依据。
This paper, through the example of the irrigation quota determination in the design of 3333 hm2 irrigation project at Damogu, Luliang County, Yunnan Province, recommends how to use Penman formula and analytical technology of computer for calculating the water requirements, optimum water consumption and optimum economical irrigation quota of crops in the red soil area of central Yunnan Province. Meanwhile, according to the climatic characteristics. physiological charactets of the crops and the regulation of water consumption,the distribution of quota and opportunities of irrigation have been determined,which provide reliable bases for the design of irrigation projects.
