Abstract:

Fresh edible soybeans have a long cultivation history in Haiyan County and represent a regionally distinctive dominant crop. In recent years, with the increase in land circulation, the production of fresh edible soybeans has begun to shift toward specialization, scaling, and intensification. Through mechanized harvesting trials, three soybean harvesters in terms of harvesting efficiency, missed-pod rate, damage rate, impurity rate, and post-harvest browning were compared in Haiyan County. By comprehensively evaluating the cost-saving and efficiency-improving advantages over manual harvesting, the Yizhuo 4TD-16 vegetable soybean combine harvester was selected as the primary recommended model for the county. To adapt to the operational requirements of this harvester, a modified integrated ridging, pressing, and leveling machine was employed to create broders with a width of 85 cm, height of 30 cm, and furrow width of 30 cm. This approach addressed the challenges of mechanized harvesting for fresh edible soybeans.

Key words: mechanical harvesting, fresh edible soybean, Haiyan county
