摘要
为探究茄衣烟叶生产中的气候资源配置情况,以“云雪1号”品种为试验材料,通过调整移栽期以改变烟株生育期内的气候指标,采用多元统计分析法研究茄衣烟叶的气候资源配置及其对烟株农艺性状及发酵后烟叶化学成分的影响。相关性分析结果显示,烟株大田期的积温、≥10℃有效积温、总降水量与总温差对烟株农艺性状各指标的影响较大,其相关系数分布范围为0.478~0.939,而积温、≥10℃有效积温、平均气温对烟叶总糖、烟碱、总氮、蛋白质含量影响较大,其相关系数分布范围为-0.955~-1.000。采用因子分析的方法在8项气候指标中提取出气候积累因子与湿度因子2个主因子,进一步通过灰色关联分析得出上述二者分别是影响烟株农艺性状和烟叶常规化学成分的主因子。以上结果表明,确定茄衣烟株移栽期的主要气候因子依据为大田生育期的气温、降水量和相对湿度的综合配置。
“Yunxue 1”variety and the multivariate statistical analysis was used to study the climate resource allocation basis of tobacco leaves for cigar wrapper and its impact on the agronomic traits of tobacco plants and the chemical composition of fermented tobacco leaves by changing the climate indicators during the growth period of tobacco plants through adjusting the period of transplanting to study the basis of climate resource allocation for the production of tobacco leaves for cigar wrapper.The results of correlation analysis showed that the accumulated temperature,effective accumulated temperature≥10℃,total precipitation,and total temperature difference during the field stage of tobacco plants had a significant impact on every indicator of agronomic traits,with correlation coefficient ranging from 0.478 to 0.939.The accumulated temperature,effective accumulated temperature≥10℃,and average temperature had a significant impact on the content of total sugar,nicotine,total nitrogen,and protein in tobacco leaves,with correlation coefficient ranging from-0.955 to-1.000.Two principal factors including climate accumulation factor and humidity factor were extracted from eight climate indicators with factor analysis.The results of grey correlation analysis showed that the two factors mentioned above were the main factors affecting the agronomic traits of tobacco plants and the conventional chemical components of tobacco leaves.It is indicated that the main climatic factors for determining the transplanting period of tobacco plants for cigar wrapper are based on the comprehensive configuration of temperature,precipitation,and relative humidity during the period of field growth.
