摘要
针对湖北省现行灌溉定额标准存在问题,采用灌溉试验成果和典型县实地调研资料,计算分析了不同分区晚稻灌溉定额计算参数及其变化规律。考虑耕作方式与灌溉模式对晚稻灌溉定额影响,计算了湖北省不同分区不同频率4种组合模式(人工耕作+浅灌适蓄、机械耕作+浅灌适蓄、人工耕作+间歇灌溉、机械耕作+间歇灌溉)晚稻灌溉定额,并进行了合理性分析。经分析,该计算成果能够更全面真实反映湖北省晚稻灌溉用水水平,并提出了不同类型灌溉定额适用条件。该研究成果对湖北省水资源管理与其他区域晚稻灌溉定额修订具有重要指导意义。
According to the problems of the current irrigation quota standard in Hubei Province, the calculation parameters of irrigation quota for the late rice in different districts and its changing law are calculated and analyzed by using irrigation test results and survey data in typical counties.Considering the impact of tillage method and irrigation mode on irrigation quotas of the late rice, the irrigation quota of late rice is calculated for different composite modes in Hubei Province (artificial tillage-shallow irrigation optimum storage, mechanical tillage-shallow irrigation optimum storage, artificial tillage-intermittent irrigation, mechanical tillage + intermittent irrigation), and the rationality analysis is carried out.The calculation results can reflect the water utilization level of the late rice irrigation in Hubei Province, and the applicable conditions of different irrigation quotas are proposed.The results of this study have an important guiding significance for the water resources management in Hubei Province and the revision of the late rice irrigation quota in other regions.
