Alfalfa seed treatment method and cold plasma test platform

Abstract

The invention discloses an alfalfa seed treatment method and a cold plasma test platform; the alfalfa seed treatment method comprises the steps: S1, putting alfalfa seeds into a vacuum device, vacuumizing the vacuum device, and then filling with helium; and S2, allowing a cold plasma generator arranged inside the vacuum device to operate and generate vacuum ultraviolet rays to irradiate the alfalfa seeds so that biological macromolecules of the alfalfa seeds experience energy transition. The invention also provides the cold plasma test platform, which comprises a vacuum device, a cold plasma generator and a sample tray arranged in the vacuum device, wherein the vacuum device is externally connected with a vacuum pump and a helium gas source; the cold plasma generator comprises a polar plate arranged inside the vacuum device and a radio frequency generator externally connected with the polar plate; a stop valve is arranged on a connecting pipeline between the vacuum device and the vacuum pump; and a purge valve is arranged on a connecting pipeline between the helium gas source and the vacuum device.

Description

technical field [0001] The invention relates to the technical field of agricultural seed treatment, in particular to an alfalfa seed treatment method and a cold plasma test platform. Background technique [0002] Since the 1970s, foreign researchers have begun to study individual technologies of modern physical agricultural engineering. Among them, low-temperature plasma seed treatment is a new seed treatment technology invented by Russian scientists. This technology has already existed in Russia and the Commonwealth of Independent States. With a certain application scale, small and medium-sized industrialized low-temperature plasma seed treatment enterprises have emerged. There are also reports in this regard in the United States, Canada and other countries. Research in Japan has found that low-temperature plasma treatment helps seeds germinate early and promotes early maturity of crops. Seeds treated with low-temperature plasma can increase the number of flowering and cro...

AI Technical Summary

Problems solved by technology

Foreign studies have proved that low-temperature plasma treatment not only has the energy action process of ionizing radiation, but also has the effect of mass deposition and charge exchange. Through the irradiation of plasma beams on seeds, the living substances in the seed embryo can be activated, and the seed coat is relatively softened. The speed of seed germination and emergence ...
