摘  要:
运用灰色系统理论对造成云霄县1999年香蕉低温灾害的相关气象因素和当年减产率进行综合分析。结果表明,气象要素间关联度最大的为每滑动5日中日最低温小于5.0℃的天数,说明此气象要素是造成香蕉霜冻灾害的最重要因素。探讨了防御低温灾害的措施,根据云霄县极端最低气温空间分布图,选择合理的种植区,增强防御低温的意识,以提高树体自身营养贮藏增强树体抵抗力为基础,选择合适的时机采取喷灌法、熏烟法和套袋法等防御措施,使低温害造成的损失降至最低程度。

摘  要:
A comprehensive analysis was conducted using the gray system theory to determine the correlation between the climatic low temperature and the banana cold injury and yield reduction in Yunxiao county in 1999.The highest correlation between them was found to be the number of days when the daily minimum temperature was below 5.0 ℃ in every sliding five days.Thus,the following recommendations were submitted for the prevention of banana cold injury:(a) map the planting areas based on the meteorological data;(b) disseminate cold injury prevention information to the farmers;(c) emphasize prevention during the early growing stage;(d) improve plant's low-temperature resistance by increasing nutrients reserve;and(e) apply water spraying,heat fumigation and/or fruit-bagging at time of broadcasted cold spells to minimize the damage.
