摘 要 為充分认识广西甘蔗种植业的现状及存在的问题，本文综述了2007～2016年广西甘蔗播种面积、总产量、单位面积产量以及主要甘蔗栽培品种和栽培技术的发展和变化情况。发现2007～2016年广西甘蔗年平均播种面积和总产量分别为105.8 hm2、7 670.5万t，占全国的60.5%、64.7%；单位面积产量在66.6～78.5 t/hm2，平均为72.6 t/hm2，高于全国平均水平。bookish2013年之后，广西甘蔗播种面积和总产量均呈下降趋势，2016年分别比2013年下降了15.5%、7.9%。但甘蔗单产从2011年之后持续提升，2016年比2011年提高了17.9%。本文还分析了广西各地级市及农垦管区的甘蔗种植情况，发现甘蔗单产较高的依次为农垦管区、玉林市和崇左市，平均分别为104.2、92.9、81.5 t/hm2。本文认为广西甘蔗种植存在规模化水平较低、机械化程度严重不足、蔗田基础设施薄弱、主栽品种单一、多系布局不够合理、自然灾害频繁等问题。因此，应该采取加快整合土地资源、加强甘蔗新品种选育和优化品种多系布局、加强蔗区农业基础设施建设、加强甘蔗种植机械的研究和推广、大力推广先进栽培技术等对策。

Abstract In order to fully understand the prent situation and problems of sugarcane cultivation in Guangxi， this paper summarized the development and changes of sugarcane planting area， total output， per unit area yield， main varieties and culture techniques in Guangxi from 2007 to 2016. The results showed that the average planting area and total production of sugarcane in Guangxi from 2007 to 2016 were 105.8 hm2 and 7670.5 million tons， accouted for 60.5% and 64.7% of the nation's respectively. The per unit area yield was between 66.6 and 78.5 t/hm2， with an average of 72.6 t/hm2， which was above the national average. Sugarcane planting area and total output declined by 15.5% and 7.9% compared with 2013's respectively. But the sugarcane per unit area yield continually improved by 17.9% from 2011 to 2016. This paper also analyzed the sugarcane planting situation of some prefecture-level cities and land reclamation districts in Guangxi. It showed that the successive order of sugarcane p
er unit area yield was land reclamation district， Yulin city and Chongzuo city， with an average of 1 04.2 t/hm2， 92.9 t/hm2 and 81.5 t/hm2 respectively. The paper indicated that there were ries of problems existed in sugarcane planting of Guangxi，好听的英语歌曲 such as low level of large scale男士快速美白， riously inadequate degree of mechanization，restaurant city weak infrastructure of sugar field， single main variety， unreasonable layout of different sugarcane lines and frequent natural disasters.Following suggestions were put forward： accelerating the integration of land resources， strengthening the cultivation of new sugarcane varietiesadventureland， optimizing layout of different sugarcane lines， Strengthening the construction of agricultural infrastructure in sugarcane planting area， Strengthening the rearch and promotion of sugarcane planting machine and promoting advanced cultivation techniques.
