为了探索玉米产量与主要农艺性状之间的关系,精准运筹肥料在玉米各个生育时期的施入量,减少化肥用量,降低土壤污染,以提高农民收入,本文应用灰色关联度分析方法,将近五年引进推广的六个玉米品种产量与主要农艺性状在高中产区进行了灰色关联度分析,为节本增效,提高化肥利用率提供了科学依据。
In order to explore the relationship between maize yield and the main agronomic traits, accurately apply the amount of fertilizers applied during each growth period of maize, reduce the amount of chemical fertilizer and reduce soil pollution so as to increase farmers’ income. In this paper, using the gray correlation analysis method, The introduction of the promotion of six varieties of maize yield and major agronomic traits in the high school producing areas were gray correlation analysis, for the cost-effective and improve the utilization of chemical fertilizer provides a scientific basis.
