| Abstract: |
| 【Objective】 The analysis could be used as a reference to determine transplanting dates at different altitudes and make full use of the natural resources of Xingshan.【Method】 The climate conditions at different altitudes and different transplanting dates of Xingshan tobacco-growing areas were analyzed, the climate feasibility indexes (CFI) were estimated,and similarity analysis of climate conditions between Xingshan tobacco-growing areas and high-quality tobacco-growing areas overseas was also conducted.【Result】 (1) On the same transplanting day (May 10),CFI values at different altitudes showed that it was the biggest at the altitude of < 800 m,the lowest at the altitude of >1 200 m,and medium at the altitude of 800-1 200 m.The similarity of the climate conditions at different altitudes between Xingshan tobacco-growing areas and high-quality tobacco growing areas overseas showed the trend of Brazil > Zimbabwe > America.At different transplanting dates,CFI values at different altitudes showed that low altitude > medium altitude > high altitude;the similarity of the climate conditions at different altitudes of Xingshan with tobacco growing areas overseas showed Brazil > Zimbabwe >America.【Conclusion】 The transplanting dates of Xingshan tobacco-growing areas at different altitudes were proposed.It was suggested that low altitude was fit for transplanting in the last ten days of April,medium altitude was fit for transplanting in the second ten days of May,and high altitude was fit for transplanting in the last ten days of May. |
