摘　　要：通过甘蔗田间试验对减量施肥及有机-无机肥配合施用的增产和增收的效应进行了探讨,旨在为甘蔗的高效施肥提供科学依据。结果表明,在农民常规施肥量的基础上减少45%肥料及有机无机肥配合施用均明显提高肥料利用率,增产增收效果显著。减量施肥的产量达到97.54t/hm2,增产6.99%,利润增加8574元/hm2;有机—无机配合施用的蔗茎产量达到115.29t/hm2,增产26.46%,利润增加13709元/hm2。By means of the sugarcane field experiment, exploring the improving effect of yield and income under reduced fertilizer application and combined application of organic and chemical fertilizer, its purpose was to provide the basis for efficient fertilization in sugarcane. The results showed that it is significantly increasing in fertilizer utilization rate and fertilizer efficiency by 45% reducing of fertilizer supply content compared with farmers＇ conventional application amount, it is also obvious improving yield and income. Besides, the combined application of organic and chemical fertilizer treatment also has the similar result. Meanwhile, the yield of reducing fertilizer treatment reached 97.54 t/hm^2, increased 6.99%, and profits increased of 13709 RMB/hm^2 in combined application of organic and chemical fertilizer treatment.
