摘要
为了解甘蔗新品种桂糖31号、32号、34号的种性和丰产性表现,为其在生产上推广应用提供依据,于2009-2011年在金光农场进行2年新植2年宿根的品种比较试验。结果表明,桂糖31号、32号、34号的蔗茎产量达到121.4～129.0 t/hm2,比对照种新台糖22号增产8.2%～15%,达到1%～5%的差异显著水平;含糖量19.03～19.27 t/hm2,比新台糖22号增11.4%～13.2%;11月~翌年2月平均甘蔗蔗糖分达到14.86%以上。这3个品种均表现明显的高产、稳产、高糖的特性,其宿根性、抗病抗虫性、抗旱能力和抗机械碾压能力优于对照种新台糖22号,适宜在金光农场和广西其他同类型蔗区种植推广,并可采用全程机械化的耕种和收获技术进行生产。
In order to understand the characteristics and prolificacy of new sugarcan varieties（Guitang 31,32,34） and provide the basis data for application in the production,a variety comparative test was conducted on two years new plant and 2 years ratoons crops from 2009 to 2011.The results showed that Guitang 31,32,34 was reached 21.4～129.0 t/hm2by yield and higher than the contrast ROC22 by 8.2%~15%,with significant different of 1%～5%;The sugar yield of Guitang 31,32,34 were got 19.03～19.27 t/hm2,increased than ROC22 with 11.4%～ 13.2%;Guitang 31,32,34 were reached 14.86% by average sucrose content during harvesting season（November to February of next year）.The three varieties were performed obvious characteristics of high and stable yield,high sucrose content,ratoon ability,insect and drought resistance ability,and machinery（compaction） harvesting resistance ability were better than ROC22.Therefore,Guitang 31,32,34 were suitable to machinery operation in all field cultivated and harvest in Jinguang state farm and the same type plantation in Guangxi.
