为研究大理州优质红大烟叶的适宜产量范围,通过田间试验和大田随机取样研究不同产量因素和产量水平的烟叶质量特征,采用相关分析、回归分析来探讨产量水平与经济性状、感官质量评价指标间的量化关系。结果表明,依据经济性状指标确定烟叶的适产范围为2655.83~3077.40 kg/hm2,但烟叶化学成分协调性较差。依据感官质量评价确定烟叶的适产范围为2243.49~2702.52 kg/hm2,烟叶化学成分协调性较好。综合考虑,大理州优质红大适产范围在2243.49~2702.52 kg/hm2,有利于大理州红大“清甜香润”风格的彰显和烟叶质量的持续健康发展。
In order to study the suitable yield range of high quality red tobacco leaves in Dali Prefecture, the quality characteristics of tobacco leaves with different yield factors and yield levels were studied by field trials and random field sampling. Correlation analysis and regression analysis were conducted to investigate the relationship between yield level and economic traits, Between the quantitative relationship. The results showed that the suitable range of tobacco leaf was 2655.83 ~ 3077.40 kg / hm2 according to economic traits, but the chemical composition of tobacco leaves was poorly coordinated. According to the evaluation of sensory quality, the suitable range of tobacco leaf was determined to be 2243.49 ~ 2702.52 kg / hm2, and the chemical composition of tobacco leaves was well coordinated. Taken together, the range of high-quality red daddy in Dali prefecture ranged from 2243.49 to 2702.52 kg / hm2, which is in favor of Dadong Hongda’s “sweet-smelling sweet” style and sustained and healthy development of tobacco quality.
