摘要
依据安徽水科院新马桥农水综合试验站1996～2001年作物水分生产函数专项试验资料建立的小麦等4种主要农作物的“作物-水模型”,结合分布于安徽淮北地区北、中、南部8个试验站（点）历年的试验统计资料,建立了作物优化灌溉制度的数学模型,并采用动态规划方法分别求出了该地区不同分区、不同水文年型小麦等4种作物的优化灌溉制度;分析确定了其经济灌溉定额以及优化灌溉的节水增产效果.为安徽淮北平原和类似地区科学、合理、高效利用灌溉水资源,实现向节水型农业的转变等提供了理论、技术指标依据和决策依据;同时对于正确指导该区农田水利规划与建设等具有重要的参考应用价值.
Based on special subject experimental data, the model of crop response to water and optimization irrigation procedure model are built up. The optimization irrigation procedure for the four kind of crops, wheat, rape, corn and soybean in the north Huaihe River plain area of Anhui province are obtained respectively by the approach of dynamic programming. At same time, economic irrigation norm are determined, and the result of saving water and increasing output of optimization irrigation are also analyzed here.
