摘要
分析了湖北烟区不同移栽期条件下的气候状况,通过定量估算气候适生性指数(CFI),合理评价了烤烟种植的气候适生性,并对各植烟县(市)建议移栽期下的气候条件与国外优质烟区进行了相似性分析,结果表明:(1)当气温稳定通过15℃、18℃、20℃和22℃分别进行移栽时,CFI值依次为0.863±0.06、0.848±0.06、0.855±0.07和0.890±0.05,表明移栽期是影响烟叶品质形成的重要因素。(2)确定了24个植烟县(市)的烤烟建议移栽期,即利川、五峰、老河口、兴山、郧西、房县、竹山和长阳等8个植烟县(市)适宜于当气温稳定通过18℃时移栽;宣恩适宜于气温稳定通过20℃时移栽;其余15个植烟县(市)适宜于低温移栽(气温稳定通过15℃移栽)。(3)湖北烟区在烤烟建议移栽期的气候条件与巴西、津巴布韦的相似程度较美国高,相似性分析为充分利用湖北烟区自然资源提供了参考依据。
Climatic factors are important conditions for tobacco growing. Therefore, many studies focused on the iniluence of climatic factors on tobacco quality. However, the studies on climatic feasibility of tobacco with different transplanting dates were few. In this paper, the climatic state of flue-cured tobacco with different transplanting dates was analyzed, and the climatic feasibility indexes （CFI） were estimated for tobacco-growing areas in Hubei. Analyses were conducted on similarity between climatic conditions of tobacco at different transplanting dates suggested for different regions in Hubei and corresponding climatic conditions in foreign high-quality tobacco-growing areas. The results were as follows ： （ 1 ） When daily air temperature increased steadily to above 15℃ , 18℃, 20℃ and 22℃ , CFIs for flue-cured tobacco at different transplanting dates were 0. 863 ± 0.06, 0. 848 ± 0.06, 0. 855 ± 0.07 and 0. 890 ± 0.05, respectively, indicating that transplanting date was the important factor to affect tobacco quality. （2） The transplanting dates were determined for 24 tobacco-growing counties in Hubei. In sites such as Lichuan, Wufeng, Laohekou, Xingshan, Yunxi, Fangxian, Zhushan, and Changyang, tobacco seedlings were suggested to transplant when daily air temperature steadily passed 18℃. In Xuan＇ en, the reasonable transplanting date of tobacco seedlings was when air temperature passed 20℃, while the transplanting date was when air temperature passed 15℃ in other 15 sites. （3） The similarity of the climatic conditions of flue-cured tobacco at different transplanting dates suggested for tobacco-growing areas in Hubei with corresponding climatic conditions in Brazil and Zimbabwe was higher than that with climatic conditions in America. The similarity analysis may be used as a reference to make full use of the natural resources in Hubei.
