【摘要】：為明確湘西煙區(qū)主產(chǎn)煙縣的烤煙大田期氣候資源區(qū)域特征,采用烤煙大田生長期的溫度、降水量、日照時數(shù)、空氣相對濕度、有效積溫等氣候因子,分析了其區(qū)域氣候差異、與國內(nèi)外主要煙區(qū)氣候差異,并進行了相似性分析和綜合評價。主要研究結(jié)論如下：①湘西煙區(qū)烤煙大田生長期的日平均溫度在20℃以上,降水量在800mm以上,日照時數(shù)在700h以上,具備了優(yōu)質(zhì)烤煙種植的優(yōu)勢。②湘西煙區(qū)烤煙大田生長期具有日均溫相對較高,前期降水量相對較多,后期降水量相對較少,日照時數(shù)適宜,空氣相對濕度較大的特點。③湘西煙區(qū)烤煙大田期氣候與國內(nèi)的遵義最為相似,其次為國內(nèi)的郴州,再次為國外的巴西。④湘西煙區(qū)氣候適宜性指數(shù)在77.60-93.79分,以花垣縣氣候適宜性指數(shù)最高,其次為永順縣,再次為鳳凰縣。湘西煙區(qū)光照、溫度、雨量與優(yōu)質(zhì)煙生長需求匹配協(xié)調(diào),適合優(yōu)質(zhì)烤煙的生產(chǎn)。
[Abstract]:In order to clarify the regional characteristics of flue-cured tobacco climate resources in the main tobacco producing counties in Xiangxi tobacco region, climate factors such as temperature, precipitation, sunshine hours, air relative humidity and effective accumulated temperature were used in the growing period of flue-cured tobacco field. The regional climate difference is analyzed, which is different from that of the main tobacco regions at home and abroad. The main conclusions are as follows: the average daily temperature of flue-cured tobacco field is above 20 鈩，
