Abstract

The natural environment in the high-altitude areas of Qinghai Province is harsh, and the ecology of its alpine meadows is seriously degraded. To improve the seeds and increase their germination rate, this paper took the wild pea seeds widely distributed in high altitude and cold areas as the research object, built an experimental platform for the biological characteristics of the electric field, and used a multi-needle circular electrode corona field generator to pretreat the wild pea seeds. Explore the effects of corona electric field, temperature, and humidity on the germination characteristics of wild pea seeds. By constructing a multi-needle circular electrode corona model and simulating the internal electric field distribution, the analysis showed that the spatial corona electric field had a consistent effect on wild pea seeds. The results of the study showed that under the conditions of a temperature of 20 ℃ and a humidity of 40%, changes in the electric field had two characteristics: promoting and inhibiting the germination of seed. The electric field generated by the applied voltage of 15 kV promoted the germination of wild pea seeds. That helped break the shells of wild pea seeds and increases their germination rate. While the electric field generated by the applied voltage of 9 kV had the opposite effect. Seeds treated with an electric field generated by an externally applied voltage of 15 kV for 30 min, under the same humidity and different temperature conditions, had the highest germination potential and germination rate at 25 ℃, and the lowest germination potential and germination rate at 15 ℃. Under different humidity conditions of 20 ℃, the seeds treated with the same electric field had the highest germination potential and germination rate at the humidity of 60%, and the lowest germination potential and germination rate at a humidity of 95%. Through the research of this paper, the germination rate of alpine wild pea was improved, so as to make efforts for low-carbon agricultural ecological protection in Qinghai, China and the world.
