Background technique

Stem mustard is also known as green cabbage head and stem mustard. There are 3 to 5 tumor-like protrusions on the outside of the leaf base on the stem. Harvesting of stem mustard requires cutting off the upper part of the fleshy stem through a harvesting device and cutting it before harvesting. The large leaves at the top are topping.

The current harvesting of tuber mustard is mainly carried out manually using cutters. Harvesting tuber mustard in a large area is labor-intensive and has poor economic benefits. Therefore, harvesters are currently required for large-area tuber mustard planting fields. However, the existing harvester cannot cut the knob-like protrusions very well. The cutting is often incomplete, or the stem knobs are directly cut to pieces, and the stem knobs are along the large leaves at the top of the stem. Problems include difficulty in removal and low harvest rate due to uneven planting of stem tuber mustard in the same field ridge.
