摘  要:
为了对寒区水稻不同栽培模式方案进行综合评价,通过田间小区试验,集成旱育稀植、分段施肥和控制灌溉技术,选取不同处理下的灌溉水利用效率、产量、有效穗数、千粒质量等试验资料,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,运用该模型对水稻不同栽培方案进行综合评价。结果表明,控制灌溉A2,基肥∶分孽肥∶拔节肥∶穗肥=4.5∶2∶1.5∶2,插秧密度21穴/m2为最优栽培模式,结果与实际试验相一致,适用于寒区水稻栽培模式评价。

摘  要:
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 A2,base fertilizer:Tillering fertilizer: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.
