【摘要】 为了预测和评估2016年崇左、百色蔗区甘蔗生产情况,采用实地调查和数据收集相结合的方法,调查了两个蔗区甘蔗苗情、品种结构、种植面积及植期、病虫害情况等。调查结果表明:2016年崇左、百色蔗区糖料蔗苗情均较好,有足够的苗数和良好的幼苗,但崇左蔗区相比2015年略差。两个蔗区的螟害发生率均较低,螟害枯心率整体低于2015年,螟害综合防治初见成效。崇左蔗区甘蔗种植面积略有增加,百色蔗区面积大幅减少。得益于"双高"基地建设,两个蔗区的品种结构得到进一步改良。建议及时加强田间管理,做好化学除草和后期甘蔗螟虫的防治工作。更多还原

【Abstract】 The seedlings situation, varieties structure and planting area of sugarcane were investigated to predict and evaluate sugarcane production of Chongzuo and Baise areas by field investigation and data collection in 2016.The investigation results showed that the seedling situation of sugarcane in Chongzuo and Baise areas was better with enough number of seedlings and seedlings growing well, but Chongzuo area was worse than that of last year.The borer pest occurrence rate in the two sugarcane areas was lower than that of in 2015, and the prevention and control of sugarcane borers has achieved a certain effect. The sugarcane planting area of Chongzuo slightly increased meanwhile Baise reduced substantially. The varieties structure rationalization of the two sugarcane areas had been further improved because the effect of "high-yield and high-sugar" sugarcane soil base construction. It was suggested to strengthen field management in time, and pay close attention to the chemical weeding and controlling of sugarcane borers.更多还原
