Background technique

White radish is a common vegetable in the daily diet of Chinese people. The cultivation of white radish in my country has a history of thousands of years, and it is grown all over the country. When white radish is planted in small plots in mountainous and hilly areas, the harvesting method is mainly manual harvesting, which has high labor intensity, low machinery utilization rate, high time and money costs, and it is difficult to complete the harvesting operation by manual labor alone. Mechanized harvesting has gradually become a trend.
