Abstract: It is critical to modernize the acquisition of tobacco in modern tobacco agriculture. This study investigated the data of tobacco acquisition. The risk occurrence of tobacco acquisition was established by using acquisition index. Acquisition risk of 91 days had great differences. Acquisition risk of 13 weeks was regular variation. Acquisition risk of 3 mouths was hourglass distribution. Due to high regularity and sensitivity and proper recognition cycle, weekly tobacco acquisition index was used as key parameter to monitor acquisition risk. The results showed that risk occurrence of tobacco acquisition was variable, periodic and regular, which supported tobacco acquisition risk management.
