摘要
为了研究模糊综合评价方法在夏玉米灌水方案优选中的应用,采用改进层次分析的模糊综合评价模型对不同灌水控制下限夏玉米的耗水量及产量特性进行评价,并结合郑州地区非充分灌溉条件下夏玉米种植试验结果进行分析。结果表明:夏玉米全生育期耗水量随灌水控制下限的增加而增加;当灌水控制下限为70%田间持水量时夏玉米产量和水分利用率最高;模糊综合评价结果与试验区试验结果相吻合。因此,改进层次分析的模糊综合评价模型可应用于夏玉米灌水方案优选的研究中,并为模糊综合评价在节水灌溉研究中的应用提供理论参考。
In order to study the feasibility of fuzzy mathematics in optimizing the irrigation scheme of summer maize, the improved analytical hierarchy process combined with fuzzy comprehensive evaluation method is used to evaluate the summer corn water consumption and yield characteristics under different irrigation lower control limit. And the summer corn planting test results under non-sufficient irrigation in Zhengzhou area is combined for analysis. The results show that when the lower irrigation control limit is 70% of the field capacity, the yield and water use efficiency of summer corn are the highest, the fuzzy comprehensive evaluation result is accorded with the experiment result. Therefore, the fuzzy comprehensive evaluation model based on improved analytic hierarchy process can be used for evaluating the water- saving irrigation and the optimization of irrigation scheme, and can provide theoretical support for the application of fuzzy comprehensive evaluation in water saving irrigation.
