Early spring rice drought seedling method and device for electric heating and ground temperature raising

The invention discloses an early spring rice drought seedling method and device for electric heating and ground temperature raising and belongs to the technical field of rice planting. The method includes the first step of seed processing, the second step of sowing and the third step of temperature control. The invention further discloses a device used in the early spring rice drought seedling method. In the seedling method, physiological properties and the development process of rice emergence and seedling growth are combined, by the adoption of a staged ground temperature control method, the optimal ground temperature and air temperature environment of rice early spring seedling is created, the processes of pesticide sterilization and acid modulation for preventing damping-off are reduced, the seedling rate and seedling quality are guaranteed, and the method is more environmentally friendly. Meanwhile, sowing is 10-15 days earlier than that in the prior art. The device is convenient to use during wiring and
