“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.
