摘　　要：甘蔗新品种‘桂辐98-296’与对照当家品种‘新台糖22号’或‘新台糖16号’在广西7个不同生态区进行对比示范试验,综合各地平均,公顷产量:‘桂辐98-296’为103.29 t,对照为82.27 t,‘桂辐98-296’比对照增产21.02 t,增幅25.55%;蔗糖分:‘桂辐98-296’为15.22%,对照为14.13%,‘桂辐98-296’比对照增1.09%(绝对值,下同);每公顷含糖量:‘桂辐98-296’为15.71 t,对照为11.65 t,‘桂辐98-296’比对照增4.07 t,增幅34.97%;每公顷经济效益分析:蔗农植蔗增收9879.40元,制糖企业增效16845.89元,工农业经济效益合计增加值达26725.29元。The comparative demonstration experiments using new sugarcane variety‘Guifu98- 296＇anddominant sugarcane variety‘ROC22＇or‘ROC16＇were conducted in 7 different ecological areas of Guangxi.The results showed that the average yields of‘Guifu98-296＇achieved 103.29 t/hm2, increased 21.02 t/hm2 comparing with CK（82.27 t/hm2）, and this was 25.55% higher than that of CK. The average sucrose of‘Guifu98- 296＇was 15.22%, 1.09%（absolute value） higher than that of CK（14.13%）. Sugar yield per hm2of‘Guifu98- 296＇was 15.71 t, increased 4.07 t comparing with CK（11.65 t）, and the increased percentagereached 34.97%. Benefit analysis per hm2 results showed that, farmer income increased 9879.40 yuan/hm2, andthe sugar enterprises got 16845.89 yuan. So the total value of industrial and agricultural economic benefitsincreased 26725.29 yuan.
