| 摘 要： | 在采用3因素5水平最优试验设计进行连续两年的田间试验基础上,通过回归分析,论述了试验条件下氮、磷、钾肥对甘蔗产量和含糖量的影响.结果表明,无论是新植蔗还是宿根蔗,氮、磷、钾的施用与产量和潜在产糖量之间都存在着二次回归关系,其单因素效应及交互效应对产量和潜在产糖量都产生影响,相对而言,氮对产量、磷对潜在产糖量的影响分别较其它两者为大;产量、纯经济效益及潜在产糖量最佳时的施肥组合为:新植蔗:XN:358.5～390,XP:115.5～171,XK:264～292.5,其取中值时的配比为1:0.38:0.74.宿根蔗:XN:430.5～526.5,XP:267～273,XK:358.5～396,其取中值时的配比为1:0.56:0.79.

| Abstract: | A experiment with three factors and five Levels has been conducted for two years,to check the effect of N,P2O5,K2O on yield and sugar content of sugarcane.Results showed that they are regression relationship between N,P2O5,K2O and yield,potential sugar yield both planting and stubble cane.Whether nutrient or interaction among three nutrient influences the yield and sugar content of sugarcane,but the effect of N on yield,P2O5 on sugar content is more significant relatively than that of others.The simultaneous rate of fertilizer combination for optimal yield,sugar content and economic income is X 23.9～26.0,X 7.7～11.4,X 17.6～19.5 for planting cane and X 28.7～35.1,X 17.8～18.2,X 23.9～26.4 for stubble cane. |
