摘要
针对豫西地区马铃薯生产水平状况和存在问题,设立氮肥、钾肥与密度的三因素试验,建立产量模型,分析各因素对产量的效应关系,提出优化栽培方案指导生产。
Based on the potato yield level and existing problems of the potato cultivation in the west Henan province, this paper set up the three-factor experiment which nitrogen,potash and density were included. Through the experiment,this paper established the yield model and analyzed each factor,seffective to the yield and proposed optimal cultivation schemes to guide the potato production.
