Abstract:

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℃.
