| 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... |
| Keywords: | maize entropy gray association analysis the assessment of irrigation benefit |
