甘蔗新品种桂糖32号在广西金光农场的表现

Performance of the new sugarcane variety Guitang 32 in Jinguang farm of Guangxi

为了解甘蔗新品种桂糖32号在广西金光农场的种性表现,于2009—2011年在金光农场蔗区进行2年新植2年宿根的品种比较试验。结果表明,桂糖32号平均蔗茎产量为121.4 t/hm2,比对照种ROC22增产5.4%;含糖量19.03 t/hm2,比ROC22增产8.9%;11月至翌年2月平均蔗糖分为15.68%,比ROC22高0.50个百分点。该品种表现高产、高糖,宿根性强,抗病虫性、抗旱能力和抗机械碾压能力优于对照种ROC22,适宜在金光农场蔗区和其他同类型蔗区推广种植。

In order to understand the characteristics of a sugarcane new variety Guitang 32 in the Jinguang farm, a sugarcane variety comparative test was conducted on 2 years new plant and 2 years ratoons crops from 2009 to 2011. The results showed that variety Guitang 32 was increased 5.4% by 121.4 t/hm2 on the average of cane yield and increased 8.9% by 19.03 t/hm2 on sugar yield, compared with the control ROC22. From November to February, the average of sucrose content was 15.68% and was higher than CK 0.50 percentage. This variety was performanced higher yield, higher sugar, better ratoon ability, higher resistance to drought diseases and pests and mechanical injury, comparing the CK. It is suitable for cultivated to Jinguang farm and other with same type regions.
