皖东江淮丘陵区不同水文年水稻优化灌溉制度的研究

依据安徽省天长市气象局1961-2008年多年气象资料和安徽省天长二峰灌溉试验重点站多年水稻灌溉试验成果,从不同水文年的水稻需水量、渗漏量、降雨量入手,利用建立的水分生产函数模型和水量平衡原理分析了皖东江淮丘陵区不同水文年水稻在不同供水条件下的优化灌溉制度。为准确客观评估皖东江淮丘陵区的水稻干旱损失,制定抗旱减灾工作预案,水资源的优化调度,合理的调整产业结构等提供科学依据。

A Study on Optimal Irrigation Schedule of Paddy in Different Hydrological Years in the Hilly Areas of Eastern Anhui Province

On the basis of the meteorological data from 1961 to 2008 of Tianchang City Meteorological Bureau and the paddy irrigation experi-ment results of Erfeng key irrigation test station, starting from paddy water requirement, seepage amount and rainfall in different hydrological years, the optimal irrigation schedules for paddy in the hilly areas of eastern Anhui province under different water-supply condition in differ-ent hydrological years are analyzed by using established water production function model and the water balance principle.The results can pro-vide scientific base for estimating the paddy drought loss, making drought-resisting and disaster-reducing plan, optimally scheduling water re-sources and rationally adjust industrial structure in the hilly areas of eastern Anhui province.
