Abstract

This study systematically investigates the key stage of tobacco stalk harvesting within China’s fully mechanized tobacco production system, evaluating mainstream technical approaches and representative equipment worldwide. It identifies that progress in mechanized stalk harvesting is hindered by several challenges, including stratified leaf collection, repeated field operations, and the constraints imposed by ridge-based cultivation systems. The study clarifies the core operational processes (stalk extraction, conveyance, fragmentation, and collection) and summarizes the structural characteristics and recent developments of key domestic components. A comparative analysis of equipment performance and applicable field conditions is also presented. Finally, development recommendations are proposed in accordance with the trend toward integrated mechanization and agronomy, as well as increasing system intelligence, providing a reference for future technological innovation and practical application.
