摘要
Abstract
In order to adjust tea planting structure and promote corresponding industry development by climatic resource of southern Jiangsu tea region, the climatic change of nonfrost period was analyzed by climatic tendency rate and Mann-Kendall (M-K) methods based on meteorological data of nine stations in southern Jiangsu tea region during 1961 to 2008. The nonfrost period showed a visible rising tendency,averagely 7 to 9-day increase every 10 years (Suxichang region). The extra short and comparatively short nonfrost period was present before 1996,while the extra long and comparatively long nonfrost period was present after 1989. Noticeably,the climate jump of nonfrost period of Ningzhen region and Suxichang region was found in 1996 and 1984, respectively, prolonging the nonfrost period by 16 days and 15 days. It was suggested that the tea planting structure of southern Jiangsu should change with the tendency. Specifically, northern part of Ningzhen and Suxichang region should make great efforts to introduce early sprouting species and properly introduce extra-early sprouting species, and meanwhile, southern part of Suxichang region should try their best to introduce and popularize extra-early sprouting species.关键词
