摘　　要：为了探索一定生态条件下旱地甘蔗栽培因素与高产高效栽培之间的相互关系，确定了种植行距、下种量及氮、磷、钾施用量5个主要栽培因素，采用五因素二次正交旋转设计，建立不同生态条件下主要栽培因素数学模型。通过模拟分析，提出了不同产量层次的优化栽培推广方案，为旱地甘蔗高产高效栽培提供了依据。In order to seek after the relationship of the main sugarcane cultivation factors and high－yeild high effect in dry land of all kinds of ecological conditions, this study select planting space, seed sowing quantities, the fertilization of N,P,K as the primary factors, use five factors and two times rotation design, the mathematic mode was set up． by means of simulation analysis, an optimize cultivation ways of different output, it is provide theoretic evidence for high yield and high effect cultivation in draught area．
