[0002] my country has a large vegetable planting area. The germination efficiency and germination rate of vegetable seeds are the main factors affecting vegetable planting. In order to improve the efficiency of vegetable agricultural planting, vegetable seeds are germinated in the early stage of planting. Germination is a measure that can cause bud growth, dormant bud development and seed germination, or promote these to happen in advance. It is called germination. Germination is an important measure to ensure that after the seeds absorb enough water, the nutrients in the seeds are quickly decomposed and circulated to supply the growth of the young embryo. Seed germination requires suitable water, temperature, ventilation and other conditions.

When the temperature sensor 28 detects that the temperature in the box 2 is lower than the set temperature, the temperature signal is quickly fed back to the controller 29. The controller 29 controls the electric heating to heat the water in the water tank 3. When the water temperature rises to the set temperature, the electric heating stops working. The controller 29 controls the circulation fan 6 to work, and the hot air in the insulation shell 4 is sent into the box 2 from the top to perform temperature compensation on the vegetable seeds in the box 2. When it is necessary to supply atomized gas to the box 2, the ultrasonic atomizer is turned on by the controller 29 to generate atomized gas in the atomizing box 7, and then the solenoid valve 75 and the circulation fan 6 are opened by the controller 29 to draw the gas in the atomizing box 7 into the first gas delivery pipe 61 through the second gas delivery pipe 74. After mixing with the constant temperature gas delivered in the first gas delivery pipe 61, it is delivered to the top of the box 2, and the seeds in the various seed cultivation trays 23 are atomized from top to bottom.
