【摘要】 通过水肥互作盆栽试验,根据玉米单阶段受旱处理下的灌溉用水量和产量的试验资料,采用熵值法确定评价指标的权重,建立了基于熵权的灰色关联模型,运用该模型对玉米灌溉效益进行评价。计算过程简单,结果与实际试验得到的数据一致,适用于玉米灌溉效益评价。更多还原

【Abstract】 Through the interaction between fertilizer and water means of the maize-grown experiment,according to the experiment data of irrigation water and yield of maize suffering from drought under a single stage,it applied entropy method to determine the weight of evaluation index and built gray association analysis method based on entropy to assess the maize irrigation efficiency.The calculation process is simple and the result coincided with experiment,so it is suitable for the assessment of the maize irrigation benefit.更多还原
