对广西主要受灾蔗区县调查结果显示:2007～2008榨季霜冻是霜害和长期低温冰冻雨雪天气危害混合发生,以低温冰冻雨雪天气危害为主,具有范围广、强度较大、持续时间长、灾害影响较重等特点。甘蔗各器官受害顺序是蔗茎基部组织(生长带)→心叶→生长点→尾部侧芽→蔗叶。霜害及低温冰冻雨雪天气对甘蔗地上(下)部蔗芽发(株)未发现实质性严重危害,或蔗茎组织受伤对甘蔗发芽(株)无实质影响;甘蔗糖厂所造成的甘蔗蔗糖分损失达0.57%(绝对值)。受害程度与品种、土壤水分状况、地理位置等因素有关。各品种(系)抗寒能力顺序是:桂糖28、桂糖27、桂糖26、桂糖24、桂糖20、桂糖21、桂糖25、柳城03-182、桂糖03-2287、粤糖00-236、园林4>台优1、桂引9、桂糖22、桂糖99-181、桂糖02-761、桂糖03-351>新台糖16、桂柳01-07、桂糖99-107>桂糖02-237、桂糖02-467、桂糖02-963、桂糖03-1403、桂糖03-2603、新台糖22、粤糖96-86、赣蔗95-108、园林6。甘蔗蔗茎组织损伤具有可恢复性。茎节伤害率是反映甘蔗受霜冻危害后品种抗寒能力较敏感、直观简便、易观察操作的指标。
According to the survey results of major affected sugarcane counties in Guangxi Province, the frost in the crop season from 2007 to 2008 is a combination of frost damage and long-term low-temperature freezing rain and snow weather hazard, with low-temperature freezing rain and snow weather as the main hazard, with a wide range of intensity and duration Long, heavy disaster and so on. The damage order of sugarcane organs was the base of cane stem (growth zone) → heart leaf → growing point → tail bud → sugarcane leaf. Frost damage and low temperature freezing rain and snow weather on sugarcane above (below) Cane Bud hair (strain) found no serious harm, or cane stem tissue damage on sugarcane germination (strain) no substantial impact; sugar cane sugar cane caused by sucrose Sub-loss of up to 0.57% (absolute value). Degree of damage and breed, soil moisture status, geographical location and other factors. The order of cold resistance of all varieties (lines) is: Gui sugar 28, Gui sugar 27, Gui sugar 26, Gui sugar 24, Gui sugar 20, Gui sugar 21, Gui sugar 25, Liucheng 03-182, Gui sugar 03-2287, Guangdong sugar 00-236, garden 4> Taiwan gifted 1, Gui cited 9, Gui sugar 22, Gui sugar 99-181, Gui sugar 02-761, Gui sugar 03-351> Xintai sugar 16, Gui Liu 01-07, Gui Sugar 99-107> Gui sugar 02-237, Gui sugar 02-467, Gui sugar 02-963, Gui sugar 03-1403, Gui sugar 03-2603, Taiwan sugar 22, Guangdong sugar 96-86, Gan sugarcane 95-108 , Garden 6. Sugarcane cane tissue damage is recoverable. Stem injury rate is to reflect the cold-resistant varieties of sugarcane affected by the frost susceptible, intuitive and easy to observe the operation of indicators.
