采用五因子二次旋转组合回归设计，对旱地蔗区影响甘蔗产量的下芽量、行距及氮、磷、钾肥的用量进行了定量研究，建立了甘蔗产量的函数模型，通过模型解析选优，得出不同目标产量水平的农艺措施组合方案，不同条件的旱地蔗寻优组合，各变量对甘蔗产量的影响程度，效应作用顺序：下芽量（Ｘ１）＞氮肥（Ｘ３）＞磷肥（Ｘ４）＞行距（Ｘ２）＞钾肥（Ｘ５），以及两因子之间的一级交互作用。为提高滇西旱地甘蔗生产水平提供了科学依据。
A five-factor quadratic rotation regression model was used to study the effects of sugarcane yield on dry-land sugar cane yield, shoot spacing and nitrogen, phosphorus and potash fertilizers. A model of sugar cane production was established. The combination of agronomic measures with different target yield levels, optimal combinations of dry and field sugarcane under different conditions, the degree of effect of each variable on sugarcane yield and the order of effect were as follows: lower shoot amount (X1)> nitrogen fertilizer (X3)> phosphate fertilizer (X4) > Row spacing (X2)> potash (X5), and a first-order interaction between two factors. Provide scientific basis for raising sugarcane production level in dry land of western Yunnan.
