摘要:

为解决楚雄‘K326’烤烟产质量波动(化学成分不协调、工业可用性下降)问题,明确施氮量、有机氮占比、留叶数的最佳组合,2023年在楚雄南华采用L9(34)正交试验,系统研究三因素对烤烟农艺性状、经济性状及内在化学成分的影响。结果表明,施氮量150 kg/hm2时,烤烟综合农艺性状表现最好,烟叶内在化学成分更协调;施氮量120 kg/hm2时经济性状表现最好。有机氮占比10%时,烤烟产量及中等烟比例最高;有机氮占比20%时,烤烟的产值、均价、上等烟比例达到最高水平;有机氮占比增加到30%时,烟叶农艺性状最好,内部化学成分更协调。留叶数18片时,烤烟农艺性状表现最好,经济性状最佳;留叶数22片时,烤烟产量最高;留叶数20片时,烟叶内部化学成分更加协调。综合考虑施氮量、有机氮占比及留叶数的影响,施氮量150 kg/hm2、有机氮占比30%、留叶数20片时,烤烟在农艺性状、化学品质方面表现最优;施氮量为120 kg/hm2、有机氮占比10%、留叶数20片时,烤烟产量最高;而施氮量为120 kg/hm2、有机氮占比30%、留叶数18片时,烤烟产值、均价、上等烟比例表现最佳。因此,适宜于楚雄当地生产实际的最佳组合方式是施氮量120 kg/hm2、有机氮占比30%、留叶数18片,可作为楚雄‘K326’的关键栽培技术指导烟草生产。

Abstract:

The study investigates the effects of nitrogen application rate, organic nitrogen proportion and retained leaf number on the yield and quality of ‘K326’ flue-cured tobacco in Chuxiong region. Through systematic experimentation, we aim to determine the optimal combination of these three key cultivation factors to provide technical support for optimizing the cultivation measures of Chuxiong ‘K326’ and improving tobacco leaf yield and quality. L9(34) orthogonal experimental design was employed to study nitrogen application rate, organic nitrogen ratio and remained leaf number in Nanhua County of Chuxiong in 2023, and we analyzed the effects of these factors on the agronomic characters, economic characters and chemical composition of tobacco. Results showed that, the nitrogen application rate of 150 kg/hm2 had the best performance on comprehensive agronomic characters, and the internal chemical components of tobacco leaves were more coordinated, the nitrogen application rate of 120 kg/hm2 had the best performance on economic characters. Organic nitrogen ratio of 30% had the best performance on agronomic characters, and the internal chemical components of tobacco leaves were more coordinated, and organic nitrogen ratio of 10% had the best performance on yield and medium quality leaves ratio, organic nitrogen ratio of 20% had the best performance on output value, average price and high quality leaves ratio. Remained leaf number of 18 had the best performance on agronomic characters and economic characters, remained leaf number of 22 had the best performance on yield, when the number of remained leaves was 20, the internal chemical components of tobacco leaves were more coordinated. Considering the effects of nitrogen application rate, organic nitrogen ratio and remained leaf number, nitrogen application rate of 150 kg/hm2, organic nitrogen ratio of 30% and remained leaf number of 20 had the best performance on agronomic characters and chemical quality of flue-cured tobacco; nitrogen application rate of 120 kg/hm2, organic nitrogen ratio of 10% and remained leaf number of 20 had the best performance on yield; nitrogen application rate of 120 kg/hm2, organic nitrogen ratio of 30% and remained leaf number of 10 had the best performance on output value, average price and high quality leaves ratio. Therefore nitrogen application rate of 120 kg/hm2, organic nitrogen ratio of 30% and remained leaf number of 18 was the best combination of this experiment. This can serve as a key cultivation technique for the tobacco variety ‘K326’ in Chuxiong to guide local tobacco production.
