Abstract Manual punching of plastic mulch is costly and time-consuming for many vegetable growers in China. However, existing punchers are not well-suited for different soil environments. This study aims to improve the efficiency of punching work, reduce labor cost, and alleviate workers' fatigue based on different soil moistures. A new puncher was designed for manual punching and four groups of experiments were carried out according to different soil moistures. The experimental results showed that the time required can be reduced by at least 12.9% and 7.5% compared to the conventional small and large diameter puncher respectively. When the soil moisture reached 27.5%, the workers' fatigue using the newly designed puncher was significantly reduced. The new puncher can effectively alleviate fatigue, increase workers' efficiency and avoid the effect of high soil moisture on farm rotation schedules. The promotion of the new puncher is conducive to the development of vegetable industry.
