| 摘 要： | 通过对安徽省淮北地区冬小麦、油菜、夏玉米、大豆等主要农作物的分阶段受旱试验,获得了连续5年的非充分灌溉试验资料,用多元回归分析法得到了这几种作物水分生产函数模型参数.运用动态规划法研究了供水不足条件下的非充分灌溉制度,得到了冬小麦、油菜、夏玉米和大豆这4种作物的优化灌溉制度.研究结果表明,在产量相同或相近时,采用优化灌溉制度进行灌溉,可明显减少作物的耗水量和灌溉用水量,提高水分生产率.

| Abstract: | Based on the observation made on the main crops such as winter wheat, rape, soybean and summer maize in Huaibei District of Anhui Province, the observed data from the deficit irrigation test for five years were obtained. The parameters for the model of crop water production function were deduced with the method of multiple regression analysis. Furthermore, optimization irrigation regime in the limited irrigation was studied for rain fed crop with the dynamic programming method. The study demonstrated that irrigation water decreased, water use efficiency increased, under the same of crops yield. Also the study could provide a powerful technical support to water-saving irrigation and agriculture in the district. |
