Embodiment 1

[0036] Embodiment 1: on the influence of cucumber seed germination potential and germination rate and germination index and vigor index

[0037] It can be seen from Table 2 that plasma treatment with different parameters can significantly promote the germination of cucumber seeds, and the germination potential of all treated seeds is higher than that of CK. At the optimum frequency, in the given voltage range, as the voltage increases, the germination potential gradually increases, which is 21.18%-38.24% higher than that of CK. The germination potential of 8200V treatment drops slightly, but it is still 18.83% higher than that of CK. %. Comparing the processing results of 2 and 4, from the perspective of processing time, the processing effect of 60 seconds is better.

[0038] Except for the treatment of 20kHz, the germination rate of cucumber seeds in the other treatments all increased, which was 1.82%-8.82% higher than that of CK. The reason is that the 20kHz discharge plas...

Embodiment 2

[0042] Embodiment 2: To the influence of wheat seed germination potential and germination rate and germination index and vigor index

[0043] It can be seen from Table 3 that plasma treatment with different parameters can also significantly promote the germination of wheat seeds. Except for the case of 20kHz, the germination potential of all treated seeds is higher than that of CK. Under the frequency of 3000Hz, within the given voltage range, as the voltage increases, the germination potential gradually increases, which is 1.07%-30.84% ​​higher than that of CK. The germination potential of 8200V treatment drops slightly, but it is still 15.71% higher than that of CK. %. Comparing the processing results of 2 and 4, increasing the working frequency has little effect on the processing results. At 1500Hz and 6000V, the discharge is relatively weak, so the treatment time is adjusted to 120 seconds. From the perspective of the treatment effect, it is worse than that without treatm...

Embodiment 3

[0048] Embodiment 3: on the influence of pakchoi seed germination potential and germination rate and germination index and vigor index

[0049] It can be seen from Table 4 that plasma treatment has certain effects on the germination of pakchoi seeds, but the treatment effects of different parameters are different. Among them, 20 seconds, 3600V and 5900V treatments can promote seed germination, and the germination potential and germination rate of seeds are all improved compared with CK. The germination vigor of the two treatments was 4.56% and 5.11% higher than that of CK, and the germination rate was 5.22% and 3.91% higher than that of CK. However, with higher voltage treatment or changing frequency treatment, the two index values ​​of the seeds were lower than those of the control, the germination potential decreased by 3.26%-11.04%, and the germination rate decreased by 1.30%-10.00%. All the treatment effects of changing the frequency are not very ideal. The reason may be ...

Abstract

The invention relates to a method for treating plant seeds by plasmas and a device for realizing the method. The plasmas of the invention are cold plasmas generated by dielectric barrier discharge under the atmospheric pressure, wherein the cold plasmas are generated in the air; the working air pressure is the atmospheric pressure; an electric source for the dielectric barrier discharge is a high-frequency and high-voltage electric source with the frequency range from 50 Hz to 20 kHz and the voltage range from 1 kV to 10 kV; and the plant seeds are treated by the plasmas for 5 to 129 sec. Thedevice for realizing the seed treating method of the invention comprises a seed treating cavity, a plasma generator for generating the plasmas in the seed treating cavity and a transmitting device capable of controlling the retention time of the seeds in the seed treating cavity. The treating operation on the plant seeds by using the atmospheric-pressure plasmas does not refer to DNA recombination, does not relate to structural genovariation of the plant seeds, and cannot cause hazards. The method only denatures the plant seeds to make the advantages become more prominent.

Description

technical field [0001] The invention relates to a method for treating plant seeds with plasma, which stimulates the growth and development of the seeds to improve plant quality and crop output value by treating the plant seeds with plasma.
