【摘要】 为了预测和评估2016年广西甘蔗生产情况,采用实地调查和数据收集相结合的方法,调查了广西6个甘蔗主产市的甘蔗苗情、品种结构、种植面积及植期、病虫害情况等。结果表明:2016年广西蔗区甘蔗苗情比上年略差,但有足够的苗数和良好的幼苗;螟害枯心率整体低于2015年,螟害综合防治初见成效,黑穗病发生率高于2015年,并有加重趋势;甘蔗种植面积连续3年下滑的局面得到控制,今年略有增加;得益于"双高"基地建设,广西蔗区的品种结构得到进一步改良。建议及时加强田间管理,做好化学除草、后期甘蔗螟虫和绵蚜虫的防治工作。更多还原

【Abstract】 To predict and evaluate sugarcane production in Guangxi in 2016, the seedlings situation,variety structure, planting area, insect pests and diseases of sugarcane in six major sugarcane producing cities of Guangxi province were evaluated by using field investigation and data collected. The results showed that the seedling situation of sugarcane in 2016 was worse than that of the last year, but the seedlings were sufficient in number and good in quality. The borer infestation rate was lower than that in2015, and the prevention and control of sugarcane borers has achieved a certain effect. The smut rate was higher than that in 2015 and tended to increase. The sugarcane planting area increased slightly this year after three consecutive years of decline in planting area. Thanks to the construction of "high-yield and-sugar" sugarcane producing base, the sugarcane variety structure in Guangxi sugarcane areas has been further improved. It was suggested to strengthen the field management in time, and to pay attention to the chemical weeding and controlling of sugarcane borers and aphids.更多还原
