香蕉低温害指标初探

Primary Research on Index of Freeze Banana

香蕉喜温怕冷,强低温常使香蕉造成伤害,重者死亡,最低气温是香蕉生长的主要限制因子,收集福建香蕉主产区代表点1966/1967、1985/1986、1991/1992、1999/2000年冬季最低气温和附件香蕉园受害程度及近几年冬季在香蕉园进行最低气温考察记载和香蕉低温害调查的图片资料,经相关统计分析表明,它们可以用一元二次方程进行拟合;香蕉的无冻害、轻冻害、中冻害、重冻害、严重冻害的最低气温分别为:5.1,2.9,0.8,-1.1,-2.8℃。

The banana like warmth climate but is afraid low temperature. The strong low temperature can often induce the banana to damage, when appear heavy coold it will be death. So the low temperature is the main limit factor which the banana grows. The text collects representative station lowest temperature in the Fujian banana primary production area within 1966/1967, 1985/1986, 1991/1992, 1999/2000 year winter,and neighborhood banana garden seeing about suffer low temperature injury recordation and picture in recent years winte. Correlation analysis indicated that the low temperature and freeze injury relation may approximately use unitary quadratic equation. The non-freeze injury and the light freeze injury and the freeze injury and the heavy freeze injury and the serious freeze injury lowest temperature respectively is： 5.1 and 2.9 and 0.8 and -1.1 and -2.8℃.
