摘要: 煙草質(zhì)量與產(chǎn)區(qū)生態(tài)條件關(guān)系密切,，同一產(chǎn)區(qū)常因生態(tài)條件的差異而造成煙葉質(zhì)量的差異,。煙葉收購、調(diào)撥以地市或縣為單位,，常造成質(zhì)量差異大的煙葉采購到一起而影響煙葉的合理利用,。同產(chǎn)區(qū)、同部位煙葉用化學成分聚類,，可有效地將不同生態(tài)差異的煙葉進行分類,。采用聚類分析方法對百色7個縣97個C3F烤煙煙葉樣品化學成分進行分區(qū)分類，為煙葉的合理利用,、生產(chǎn)技術(shù)改進提高,、產(chǎn)區(qū)定向栽培技術(shù)配套提供依據(jù)。試驗結(jié)果表明,，百色煙區(qū)可分為3個區(qū),，Ⅰ區(qū)包括隆林縣、西林縣和田林縣,；Ⅱ區(qū)包括樂業(yè)縣,、凌云縣和德保興旺、撫平,、敬德等部分鄉(xiāng)鎮(zhèn),；Ⅲ區(qū)包括靖西縣大部和德保縣樸圩,、都安,、錄峒、東陵,、那甲等部分鄉(xiāng)鎮(zhèn),。3個區(qū)煙葉質(zhì)量特色明顯，且從外觀質(zhì)量,、化學成分,、感官質(zhì)量對其煙葉質(zhì)量進行了綜合評價分析。Abstract: Cluster analysis was employed on the chemical compositions of 97 flue-cured tobacco leaf samples (C3F) from seven counties of Baise, Guangxi to enhance tobacco leaf utilization, tobacco production technology and related cultivation management in different regions. Results showed that three regions could be divided in Baise. The first included Longlin, Xilin and Tianlin, and the second included Leye, Lingyun and several towns of Debao, such as Xingwang, Wuping, and Jingde etc. The third included most parts of Jingxi and some towns of Debao, such as: Puxu, Duan, Lutong, Dongling, Najia, etc. The flue-cured tobacco leaves in the three parts exhibited evident quality characteristics including appearance quality, chemical composition and sensory quality.
