摘　　要：为了研究在甘蔗生产上一次性混施生物有机肥+无机复合肥的增产增收和化肥减施的效果,指导本地农户增施生物有机肥和减施化肥,提高生产效益,以当地主推品种桂糖46号为试验材料,以当地甘蔗专业种植大户自配方施肥为对照,研究施用无机化肥、生物有机肥、生物有机肥+无机复合肥混施对甘蔗产量、产量构成因素和经济效益的影响。结果表明,甘蔗一次性施用生物有机肥+无机复合肥可以明显提高产量和经济效益,其中处理5(施肥本草生物有机肥1455 kg/hm^(2)+盛戈·噻虫嗪药肥1215 kg/hm^(2))在减施化肥近一半的条件下,比对照增产15.16%,经济效益提高19.65%。To study the effects of a one-time mixed application of bio-organic fertilizer+compound inorganic fertilizer on increasing yield and income,as well as reducing chemical fertilizer application in sugarcane production,and guiding local farmers to increase the application of bio-organic fertilizer and reduce chemical fertilizer use to improve production efficiency,this experiment used the locally recommended variety Guitang 46 as the experimental material.The experiment compared locally sugarcane-specialized large-scale farmer’s custom formula fertilization as a control and investigated the effects of applying inorganic fertilizer,bio-organic fertilizer,and the mixed application of bio-organic fertilizer+inorganic fertilizer on sugarcane yield,yield components,and economic benefits.The results indicate that the one-time application of bio-organic fertilizer+compound fertilizer significantly increased yield and economic benefits.Among them,Treatment 5(applying“Bencao”bio-organic fertilizer 1455 kg·hm^(-2)and ShengGe thiamethoxam fertilizer 1215 kg·hm^(-2))under the condition of reduced chemical fertilizer by nearly half increased the yield by 15.16%compared with the control,and the economic benefits increased by 19.65%.
