Embodiment approach
[0044] In a preferred embodiment of the present invention, the power supply 11 is an AC power supply, the power supply input is 0-220V, the output frequency is 5-20KHz, and the discharge power is 10-30W. The high-voltage electrode 5 is a steel rod in the center of the reactor, and the electrode shape is a cylinder with a diameter of 1-3 mm. The insulating sleeve 6 is a polytetrafluoroethylene wrapped on the outside of the high-voltage electrode 5, and the shape of the insulating sleeve is a cylindrical shape with a hollow diameter of 3-5 mm. The medium sleeve is cylindrical porous ceramic, made of alumina, with an inner diameter of 8 mm, an outer diameter of 10 mm, and a length of 100 mm; the porosity is 50%. The low-voltage electrode 12 is a thin copper wire wound on the outside of the dielectric sleeve 13, with a diameter of 0.2 mm and a winding interval of 2-5 mm.

[0049] Example 1 Wheat seed germination experiment
[0050] The seeds are randomly divided into four groups, each group has 3 samples, and each sample contains 50 wheat seeds, and then the activated water is prepared by using the above-mentioned low-temperature plasma discharge device of the present invention, and the discharge power is adjusted to 30W, the discharge gap is 5mm, and the gas flow rate is adjusted. 5L / min, respectively discharge 0 (control), 5, 10, 15min. Different discharge times correspond to different groups. Petri dishes were used for germination on paper, and control and different activated water were used to keep the germination bed moist. The germination test was carried out in an electric heating constant temperature incubator, and the germination temperature was controlled at 20 °C. After culturing for 8 days, observe the growth of the seeds, as shown in Table 1:

[0054] Example 2 Soybean Seed Germination Experiment
[0055] The seeds were randomly divided into four groups, each group had 3 samples, and each sample contained 20 soybean seeds, and then activated water was prepared by using a low-temperature plasma discharge device. The discharge power was adjusted to 30W, the discharge gap was 5mm, and the gas flow was 5L / min. Discharge for 0 (control), 5, 10, and 15 min respectively. Different discharge times correspond to different groups. Petri dishes were used for germination between papers, control and different activated water were used to keep the germination bed moist, and the germination test was carried out in an electric heating constant temperature incubator, and the germination temperature was controlled at 20 °C. Cultivate for 8 days, observe the growth of the seeds, the results are shown in Table 2:
