Research status and development trends of harvesting technologies and equipment for stem lump mustard

Currently, mechanization level for stem lump mustard harvesting in China remains low, with high reliance on manual labor．Mechanized harvesting is essential for achieving full mechanization throughout production process．By reviewing suitable for mechanized planting pattern and variety development of stem lump mustard, unique harvesting characteristics were clarified, and agronomic characteristics and key points for mechanized harvesting were systematically identified．Based on recent developments of harvesting technologies and equipment for stem lump mustard in China, current main challenges in mechanized harvesting were identified．Accordingly, development strategies suited for hilly and mountainous areas were proposed: promoting standardized and uniform planting practices for stem lump mustard, designing harvesters based on mechanical damage mechanism, and enhancing intelligence, collaboration, adaptability, and maneuverability of harvesters operating for hilly and mountainous areas．
