In 2016 year Taiwan's planting onion area is about 1,337 hectares. The planting area is mainly in Pingtung County, Kaohsiung City, Yunlin County and Changhua County. In the cultivation and management process of onions, there are many work items to be carried out, such as land preparation, planting, seedling, seedling, planting, spraying, cultivating and weeding, fertilization, harvesting and harvesting and grading screening. Although the land preparation, mulching, spraying, and cultivating hoeing projects have all been replaced by machinery, the mechanization of the whole onion industry is still low, and there is still no suitable machinery to replace manpower in the harvesting and planting parts. In the face of the aging of rural manpower, young labor does not make up and the shortage of labor, the mechanization of onion cultivation management is becoming increasingly urgent.
