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 ...
