广东冬季寒害对香蕉产量的影响

广东丰富的气候资源有利于香蕉生产的发展，但冬季寒害仍可使香蕉生产遭受重大损失，即使冬季最温暖的粤西南亦难幸免。阐述了广东香蕉寒害发生的情况，对几次突出的冬季寒害及其危害进行分析。严重影响广东香蕉主产区的寒害虽然平均约5年左右一遇，但是20世纪90年代寒害出现较频繁，加上反季节种植的春夏蕉由于经济效益较高，种植面积迅速扩大，使得其抽蕾或花芽分化在冬季，造成香蕉遭受寒害的几率增大，对香蕉产量影响很大。为此，广东香蕉生产的发展要重视寒害、风害及市场变化带来的风险，必须因地因时制宜，合理布局，搞好防灾减灾。

Impacts of Cool Injury in Winter on Banana Yields in Guangdong Province

Though abundant climate resources are favor to the development of banana production, banana suffers magnitude lose for cool injury, even in southwest where is the warmest area in Guangdong. The effect of cool injury on banana are analyzed. The cool injury, which severely impact on banana growth, happened every 5 years normally in Guangdong, but cool injury comes frequently during the 90's of last century. Because of more economic benefit, the plant area of counter season banana expands quickly, and the bud bursting or differentiation is in winter, the potential fatalness of meeting cool injury is increased, and resulted in more impact on banana yield. So the banana planting should be think much of cool injury, wind damage and risk of market, and the situation of site and time in Guangdong, and do well on avoid and mitigation disaster.
