Seedling throwing is an important method of rice planting, which is mainly used in the rice with high germination rate.

The common types of seedling throwing machines are mainly the back hanging type and the cone disk type. In the future development process, we can start with rice with higher varieties to solve the problem of lodging, and expand the planting and accumulation of throwing seedlings<br>
