摘要:

针对鄂北地区干旱现状，采用长渠灌溉试验站水稻试验成果，对ORYZA模型进行了率定与验证。利用ORYZA模型模拟评价了中蓄、浅灌和湿润3种现行灌溉模式。针对现行灌溉模式存在问题，根据不同灌溉下限和灌水定额设置了不同方案，采用模型对不同方案进行了优化分析，提出了鄂北地区水稻适宜的灌溉模式：蓄水深度为60 mm；返青期和抽穗开花期灌溉下限为0，黄熟期自然落干，其他生育阶段灌溉下限设定为耕作层土壤饱和含水率的80%；灌水定额为30~40 mm/次。

Abstract:

According to water shortage of North Hubei Province, the ORYZA model was calibrated and validated with the results of experiments of Changqu Experimental Irrigation Station. The current irrigation modes, including storage irrigation mode, shallow mode and wet irrigation mode, were analyzed using ORYZA model. According to the different lower limit of irrigation and irrigation quotas, the different irrigation modes were set. The different irrigation modes were optimized with the rice growth model. The appropriate irrigation mode of rice in Northern Hubei Province was proposed that the store-rainfall depth was 60 mm; The irrigation lower limit was 0 mm at returning green stage and flowering stage, and eighty percent of saturated soil water content at other growth period; The moisture dry naturally in yellow ripe stage; The irrigation quota was 30~40 mm.
