2、拋物線"變化,感官質(zhì)量主要表現(xiàn)在香氣量上的變化,煙葉中氯離子含量隨土壤水溶性氯含量和氯化鉀用量的增加而增加,煙葉中的鉀氯比主要受氯離子含量影響,土壤水溶性氯含量和施氯量對煙葉氯含量的影響和互作效應(yīng)均達(dá)到極顯著,施用氯化鉀可以降低生產(chǎn)和生態(tài)成本,生產(chǎn)上建議南平煙區(qū)采用45kg/hin2氯化鉀用量較為適宜.關(guān)鍵詞:烤煙;氯化鉀;產(chǎn)質(zhì)量中圖分類號:$572.062文章編號:1007—5119(2009)04.0031—06DOl:10.39690.issn.1007.5119.2009.04.007EffectofPotass

8、yieldandquality氯是煙草生長發(fā)育必需的營養(yǎng)元素,與煙葉光合作用和氮代謝密切相關(guān).氯素含量是煙葉質(zhì)量的重要指標(biāo),尤其是與煙葉的燃燒性,吸濕性和彈性密切相關(guān),煙葉中的最佳含氯量在O.3%～O.8%之間I1J.根據(jù)"全國煙草平衡施肥試驗示范與推廣"項目研究的結(jié)果,優(yōu)質(zhì)煙栽培土壤含氯量要求為25~30mg/kg
