文章在分析辽宁省水稻生产用水现状的基础上,深入剖析水稻需水特性和影响因子,采用典型调查法、灌溉试验法和彭曼法相结合的方法,分区、分降水频率研究制定了辽宁省水稻灌溉用水基本定额,为辽宁省水资源配置、灌溉规划设计、修订辽宁省地方标准《行业用水定额》及落实国家用水效率红线和用水总量控制红线提供技术支撑,为推进辽宁省节水型社会建设提供基础保障。同时,也为国内其它地区研究制定水稻用水基本定额提供借鉴和参考。
Based on the analysis of present situation of rice production water in Liaoning Province, the water requirement characteristics and influencing factors of rice in depth were analyzed. The methods of typical investigation, irrigation test and Pengman method were combined to study the frequency of precipitation, The basic quotas of irrigation water provide technical support for Liaoning Province’s water resources allocation and irrigation planning and design, revising the Liaoning Province local standard “industry water quota” and implementing the national water use efficiency red line and total water consumption control red line. In order to promote Liaoning Province’s water-saving society Construction to provide basic protection. At the same time, it also provides reference and reference for other regions in China to study and formulate basic quotas for rice water.
