Background technique

Transplanting is an advanced production process for crop production. Seedlings are transplanted to the field after cultivating strong seedlings in seedbeds or paper cups. The transplanting method realizes that the large and small seedlings can be planted separately, and the row and row spacing of the seedlings after transplanting are consistent in size, which is beneficial to field agronomic management. It can avoid a series of problems such as uneven seedling emergence, lack of pond, need for multiple replanting, inconsistent seedling density and inconsistent growth speed in the direct seeding method, which affect crop yield. However, if the manual method is used for transplanting, it is labor-intensive, time-consuming, and increases costs, especially for large-scale planting, and mechanized operating machinery is urgently needed. the
