烤煙新品系HN2619在湘南煙區生態適應性研究

摘要 為驗證烤煙新品系HN2619在湘南煙區的生態適應性，于2020—2022年在永州市江永縣、江華瑤族自治縣、寧遠縣、新田縣，以當地主栽品種云煙87為對照，通過大田試驗種植，對參試品種的主要生育期、植物學性狀、農藝性狀、抗病性、外觀質量、經濟性狀以及初烤煙葉內在化學成分進行了對比分析。結果表明，HN2619大田生育期適中，株型為塔型，葉數較多，葉形長橢圓，對普通花葉病和赤星病抗性較好，產量、產值與對照相似，內在化學成分與對照相當。HN2619整體表現與當地主栽品種云煙87（對照）相當，表現出較好的生態適應性，可作為推廣品種（系）加大示范種植面積，同時應做好調制措施配套及感官評吸質量分析等工業驗證分析。

Abstract In order to verify the ecological adaptability of new flue-cured tobacco line HN2619 in southern Hunan，field experiments were carried out in Jiangyong County，Jianghua Yao Autonomous County，Ningyuan County and Xintian County of Yongzhou City from 2020 to 2022，with Yunyan 87 as the control.The main growth period，botanical traits，agronomic traits，disease resistance，appearance quality，economic traits and chemical components of flue-cured tobacco leaves of the tested varieties were compared and analyzed.Results showed that HN2619 had the characteristics of moderate growth period in the field，tower-shaped plant，more leaves，long elliptical leaf shape，good resistance to common mosaic and brown spot disease.The yield and output value of HN2619 were similar to those of the control，and its internal chemical composition was equivalent to that of the control.The overall performance of HN2619 was similar to that of Yunyan 87 （CK），which showed good ecological adaptability and could be used as an extension variety （line）.The demonstration planting area should be increased，and the industrial verification analysis should be done well，such as the matching of modulation measures and sensory smoking quality analysis.

永州市位于湖南省南部（24°39′～26°51′N，111°06′～112°21′E），地勢三面環山、地貌復雜多樣，氣候類型屬中亞熱帶大陸性季風濕潤氣候。該區是濃香型煙葉產區，煙葉呈現明顯的焦甜-醇甜香味風格特征，烤煙年種植面積2萬hm2，年產量約3.9萬t，是湖南省第二大煙葉產區，也是全國濃香型烤煙主要產區之一。

品種遺傳特性是烤煙產質量形成的基礎，同時種植地的自然生態條件和栽培措施與煙草品種的優質穩產和風格彰顯密切相關［1］。研究認為，不同海拔高度和經緯度土壤的吸水性、導水性、保肥性、保溫性和導溫性以及太陽輻射等因素對烤煙煙葉香吃味以及與香氣形成相關的化學成分含量有明顯影響［2-5］。……
