基于灰色关联度分析对新型水溶肥料在花生喷施效果的优选

Optimization of Spraying New-type Water-soluble Fertilizers in Peanuts Production Based on Grey Relational Analysis Model

为了探讨不同类型新型水溶肥料在花生上的应用效果,筛选出适合花生生产应用的新型水溶肥料种类,笔者应用灰色关联度分析模型对6种新型水溶肥料在花生生产上的应用效果进行了评价。从产量角度看,以微量元素水溶肥料增产效果最好,增产幅度为10.11%;从对花生生物学性状影响看,喷施微量元素水溶肥料、大量元素水溶肥料等处理的花生生物学性状综合表现较好;喷施含氨基酸水溶肥料、含海藻酸水溶肥料、含腐植酸水溶肥料等能改善花生品质性状。综合产量、品质和经济效益三方面的效果,花生生产上推荐使用微量元素水溶肥料、大量元素水溶肥料和含氨基酸水溶肥料。

By experimenting with different types of water-soluble fertilizers in peanuts production,the application effects were acquired and the appropriate fertilizers were screened out.Using grey relational analysis model,application effects of six different types of fertilizers in peanuts production were evaluated,and the following conclusions were reached.Firstly,from the perspective of yields,the effect of water-soluble fertilizers containing microelements was proved to be the best,and increasing extent reached 10.11%.Secondly,from the perspective of impacts on peanuts＇ biological properties,the comprehensive effects of water-soluble fertilizers plus microelements and water-soluble fertilizers plus nitrogen,phosphorus and potassium were better,while water-soluble fertilizer with amino-acids,water-soluble fertilizer with alginate and water-soluble fertilizer with humic-acids were capable of improving peanuts＇ properties to some degree.Thirdly,from the perspectives of yields,biological properties and economic benefits,water-soluble fertilizers in combination with microelements,water-soluble fertilizers with nitrogen,phosphorus and potassium and water-soluble fertilizer with amino-acids were recommended.
