The capillary effect can improve the microenvironment of the tobacco seeds, effectively maintain the humidity of the seedling tray, improve the germination rate, and increase the contact area between the seeds and the commercial matrix. After the traditional seeder completes the entire process of tray loading and sowing at one time, the topsoil needs to be spread manually, which is uneven after spreading and labor-intensive, time-consuming and labor-intensive. In order to explore the method of spreading commercial topsoil to reduce work and cost, improve quality and increase efficiency in the seedling raising stage, a fast, labor-saving and labor-saving method of spreading topsoil is selected to replace manual labor.
