摘　　要：通过研究甘蔗桂辐98-296单芽、双芽段直接补种桂糖46号宿根蔗的影响与效益分析,解决宿根蔗缺株断垄问题、产量低等问题,为推广应用提供依据。通过桂辐98-296单芽、双芽段2个补种处理,均获取较好的增产效果,且2种补种方式出苗率、成茎率均无显著差异,试验结果表明:桂辐98-296单芽、双芽段2个补种比对照分别增产比对照分别增产15.32、16.75 t/hm^(2),分别比对照增产22.63%、24.74%,测算经济效益,分别增收5047.4、5870.2元/hm^(2),说明桂辐98-296单芽、双芽段2个处理直接补种桂糖46号宿根蔗均可实现增产、增收,同时可以延长宿根年限。The effect and benefit analysis of sugarcane Guifu98-296 were studied in order to solve the problem of lack of sugarcane plants and low yield.The results showed that the yield of using Guifu98-296 single bud and double buds was increased by 15.32 and 16.75 t/hm^(2),22.63%and 24.74%,respectively,compared with the control.The yield of Guifu98-296 single bud and double buds were increased by 5047.4 and 5870.2 yuan/hm^(2),respectively.The results presented that the yield and benefit of sugarcane could be increased by using Guifu98-296 single bud and double buds.
