基于熵权的灰色关联模型在水稻栽培中的评价
Application of the Gray Association Analysis Method Based on Entropy to Assessment of Rice Cultivation
摘要
Abstract
In order to make a comprehensive evaluation of different cultivation models to rice in cold regions ,This paper through the field experiment ,integrated raising sparse ,sub-fertilization and control irrigation technology ,selecting the rice yield,irrigation water use efficiency ,effective panicles and grain weight experimental data ,it applied entropy method to determine the weight of evaluation index and built gray association analysis method based on entropy to assess the different cultivation models .The results shows that the best cultivation models is control irrigation A 2 ,base fertilizer:Tillering fer-tilizer:Jointing fertilizer:panicle fertilizer=4.5:2:1.5:2,the density of planting is 21hole/m2 ,the result was coincided with experiment ,so it is suitable for the assessment of the cultivation models in cold regions .关键词
