In order to explore the basis of climate resource allocation in the production of tobacco leaves for cigar wrapper. Taking“Yunxue-1”variety as the test material，the climate indices during the growth period of tobacco plants was changed by adjusting the transplanting period，and the multivariate statistical analysis method was used to study the basis of climate resource allocation of tobacco leaves for cigar wrapper and its influence on the agronomic traits of tobacco plants and the chemical composition of tobacco leaves after fermentation. The results of correlation analysis showed that The results of correlation analysis showed that the accumulated temperature，≥10℃ effective accumulated temperature，total precipitation and total temperature difference had a great influence on the agronomic traits of tobacco plants，and the correlation coefficient was between 0.478 and 0.939. The accumulated temperature，≥10℃ effective accumulated temperature and average temperature had a great influence on the total sugar, nicotine，total nitrogen and protein content of tobacco leaves，and the correlation coefficient was between -0.955 and -1.000. Through factor analysis，two main factors of climate accumulation factor and humidity factor were both extracted from eight climate indicies. Further through grey correlation analysis found that the above two factors were the main factors affecting the agronomic traits of tobacco plants and the conventional chemical components of tobacco leaves. Therefore，the main climatic factors determining the transplanting period of tobacco plants for cigar wrapper should be based on the comprehensive configuration of temperature，precipitation and relative humidity during the field growth period.
