水稻需水量等值线图课题是全国协作项目。贵州省的这项工作由省水利科研所牵头,有关单位协作,在八个地州市进行了灌溉试验。从1983年7月至1988年4月,经过5年努力,完成了试验研究任务。工作中整编并分析了15个灌溉试验站1979年以来的水稻需水量实测资料,收集和运用了62个气象站(台)1971—1985年连续15年的主要气象资料,按规定用彭曼公式,做了大量分析计算工作,最终提出了研究报告和水稻生育期参考作物需水量等值线图、水稻生育期特征需水 The project of contour map of rice water demand is a national collaborative project. This work in Guizhou Province, led by the provincial water conservancy scientific research institutes, the units involved in the cooperation in the eight prefectures and cities conducted irrigation experiments. From July 1983 to April 1988, after five years of hard work, the task of experimental research was completed. During the work, the survey data of paddy water demand of 15 irrigation experimental stations since 1979 were compiled and analyzed, and 62 meteorological stations (stations) were collected and used for 15 years of major meteorological data from 1971 to 1985, according to the regulations, , Made a lot of analysis and calculation work, and finally proposed the research report and rice growth period reference crop water demand contour map, rice growth period characteristics of water
