In general, cassava planting is divided into ridge planting. In the prior art, it is inconvenient to plant soybean and cassava together in the same soil ridge. The growth rates of soybean and cassava are different, it is inconvenient to cut the mature soybean straw separately, and it is inconvenient to process the large ridge and the small ridge separately, thereby reducing the application range of the device.
