Abstract
The plasma seed processor was used to treat maize seeds (No.2-Zhunuo), and the effects of plasma treatment of the maize seeds on the biological properties and yield were studied by different doses (250 mA - 2000 mA). The results showed that the effect of plasma treatment on the biological characters of maize was different, and the plant characters and yield of maize in the eight groups of plasma treatment were significantly higher than that of untreated (CK), especially the treatment current (dose) of 1500 mA, 1250 mA, and 750 mA, respectively, which had significant changes in the effect of maize plant traits. From the yield point of view, the top two are: plasma dose 1500 mA, and 1250 mA. The plasma doses of 750 mA, 1000 mA, and 1500 mA were selected from the fruit number of maize. The disease resistance of treated maize is also better than that of untreated maize (CK). In a word, the yield, plant traits, and disease resistance of maize seeds can be improved to different extent by different doses of plasma.

The breeding of traditional crops, especially vegetables, adopts traditional breeding methods with long cycle and low efficiency

High-voltage arc ionization of air nitrogen and oxygen molecules has been used to produce plasma irradiation combined with alternating inductance, by adjusting the different current treatment of some seeds [12] [13] [14], but it has been found that the treatment group is not many, the current interval stage is large, the treatment dose is rough, and it is easy to lose some plant biological properties due to the small dose
Summary
The breeding of traditional crops, especially vegetables, adopts traditional breeding methods with long cycle and low efficiency. We have used atmospheric pressure dielectric barrier plasma discharge at room temperature for some vegetables (tomato, eggplant, etc.), seed treatment [1]-[8] a decade ago, including the Chinese academy of sciences institute of physics for chili [9], lettuce [10], cucumber [11] and other crops to do plasma irradiation technology research, have achieved better results These techniques mainly use atmospheric pressure dielectric barrier discharge plasma to produce high pressure outside the parallel plate, by adjusting different high pressure to achieve the treatment of different plasma dose of plant seeds, the related vegetable plants have better stress resistance and yield effect. This research provides a new technical support for increasing the yield of maize and improving the benefit of agricultural production
