| 摘 要： | 对广西柳江县蔗区2008年元月13日至2月5日持续性低温雨雪冰冻的极端天气造成的甘蔗受害情况进行了调查，全县未砍收的15300hm^2甘蔗全部受到冻害，其中叶片干枯、生长点和侧芽被冻死，蔗茎组织严重变质的甘蔗有2100hm^2，叶片大部分干枯，生长点和侧芽严重冻伤，蔗茎内组织大部分变质，且有轻微酒味的有8600hm^2；生长点和侧芽受冻伤，但茎内组织没有明显变质的有4700hm^2。在同一气候条件下，不同的甘蔗品种耐寒性有很大的差别，新台糖22号耐寒性表现比较差，而桂糖21号、桂糖98／296等品种的耐寒性表现较强。

| Abstract: | The frostbitten sugarcanes, for durative cold rain and snow as well as frost weather were investigated in Liujiang sugarcane planting area of Guangxi from January 13 to February 5, 2008. There were total 15300 ha growing sugarcanes suffered from freezing injuy, and there were 2100 ha most severe frostbitten sugarcanes （all leaf parched blight, growing point and lateral bud were freeze to dead, and all stems were severe deteriorative change）. There were 8600 ha severer frostbitten sugarcanes （most leaf parched blight, growing point and lateral bud badly were frostbited, and most stems were severe deteriorative change）. There were 4700 ha slight frostbitten sugarcanes （growing point and lateral bud were frostbited, but stems were not significant deteriorative change with slight alcohol smell）. Under the same climate condition, there were different cold resistances for the different sugarcane varieties. The sugarcane variety ROC22 was the most worst, and the GT21 and GT98/296 were the most best. |
