[目的]了解甘蔗新品种桂糖03-2287的蔗茎产量和蔗糖分表现,为其在甘蔗生产上推广应用提供科学依据。[方法]对2011~2012和2012~2013年度广西甘蔗品种区域试验点桂糖03-2287和对照新台糖22号(ROC22)2年新植和1年宿根试验以及生产试验所获得的相关数据进行综合分析。[结果]桂糖03-2287第1、2年新植平均甘蔗产量分别为100.00和106.67 t/hm2,分别较对照增加10.58、12.47 t/hm2;从11月到次年2月份,平均蔗糖分分别为13.46%和13.77%,较对照低0.43和0.47个百分点;平均含糖量分别为13.31、14.70 t/hm2,分别比对照增加7.5%和10.3%。宿根平均甘蔗产量为113.37 t/hm2,较对照高23.8%;平均蔗糖分为13.99%;平均含糖量为15.81 t/hm2,比对照增加19.6%。在生产试验各试点中,桂糖03-2287的甘蔗产量均比对照ROC22高,平均较对照增加9.6%。[结论]桂糖03-2287在新植和宿根中,较当前的主栽甘蔗品种ROC22更为高产、稳产,单位面积产糖量更高,新植蔗的蔗糖分比ROC22略低而宿根蔗无明显差异,应属一个中晚熟优良甘蔗品种,可在广西甘蔗生产上因地制宜地推广应用。
[Objective] The research aimed to understand the cane yield and sucrose content of the new sugar cane variety Gui-03-2287, which provided a scientific basis for its popularization and application in sugarcane production. [Method] The data of 2-year newly-planted and 1-year pest-rooted experiment of Guangxi sugar cane variety regional trial Guandi 03-2287 and ROC22 of ROC22 in 2011 ~ 2012 and 2012 ~ 2013 and the relevant data obtained from the production test were conducted Comprehensive analysis. [Result] The average sugar cane yield of newly planted guanose 03-2287 in the first and second year was 100.00 and 106.67 t / hm2, respectively, 10.58 and 12.47 t / hm2 higher than the control respectively. From November to February, the average sucrose content Respectively 13.46% and 13.77%, lower than the control by 0.43 and 0.47 percentage points; the average sugar content was 13.31 and 14.70 t / hm2, respectively, increased by 7.5% and 10.3% respectively compared with the control. The average output of sugarcane was 113.37 t / hm2, which was 23.8% higher than that of the control. The average sucrose content was 13.99%. The average sugar content was 15.81 t / hm2, increased by 19.6% compared with the control. In the pilot production trials, sugarcane production in Guandi 03-2287 was higher than that in the control ROC22 with an average increase of 9.6% over the control. [Conclusion] Guitang 03-2287 was more productive and stable than the current main cultivated sugarcane variety ROC22 in newly planted and perennial roots, with higher yield of sugar per unit area. The sugarcane content of newly planted sugarcane was slightly lower than that of ROC22, No significant difference, should be a middle-late good sugarcane varieties, sugar cane production in Guangxi can be promoted according to local conditions.
