Currently, dryland transplanting operations primarily utilize single- or multi-plant transplanters, which primarily consist of independent planting groups, each driven by its own ground wheel. Therefore, they can be used with tractors of varying sizes to form 2-6-row transplanters, creating a modular design. However, the number of rows of seedlings that can be transplanted with existing transplanters depends on the size of the tractor, resulting in high operating costs, poor practicality, and low efficiency. These transplanters are unsuitable for mass planting of crops such as leeks, which have well-developed root systems and long, dense fibrous roots. Summary of the Invention
