Embodiment Construction

[0015] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention adopts gas-phase dielectric barrier discharge plasma system (such as figure 1 ). It is mainly composed of adjustable frequency AC high-voltage power supply, reactor and electrical parameter detection system. The peak voltage adjustment range of frequency-adjustable AC high-voltage power supply is 0-50kV, and the frequency is 50-1000Hz. The reactor used in this study is a screen-plate dielectric barrier discharge reactor (such as figure 2 ), the reactor wall 10 is a plexiglass tube, the high-voltage electrode 11 is a stainless steel sheet with a thickness of 2mm, adopts a mica sheet or a quartz glass sheet 12 as a discharge medium, and the ground electrode 13 is a dense stainless steel mesh, and the seeds to be treated are filled in the ground on electrode 13. During treatment...

Abstract

The invention discloses a seed processing device and method for improving the drought resistance of wheat buds. The device comprises an adjustable frequency alternating current high voltage power supply, a reactor and an electrical parameter detection system. The peak voltage of the alternating current high voltage power supply can be adjusted in 0-50 kV, and the frequency is adjustable in 50-1000 Hz; a stainless steel sheet is adopted as a high voltage electrode; a quartz glass sheet used as a discharge medium clings to the bottom surface of the high voltage electrode; and a metal mesh is adopted as a grounding electrode. The high voltage terminal of the alternating current high voltage power supply is connected with the high voltage electrode of the reactor, and the low voltage terminal of the alternating current high voltage power supply is connected with the grounding electrode of the reactor. A digital oscilloscope, a voltage probe and a current probe form the electrical parameter detection system which is used for detecting a discharge voltage and a current signal. The device and the method can promote the germination of wheat seeds under a drought condition and promote the growth of wheat seedlings under the drought condition, the membrane lipid peroxidation level of buds is reduced after discharge treatment, damages of oxygen radicals to the buds are reduced, and the discharge treatment improves the drought resistance of the buds.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to a seed treatment device and method for improving the drought resistance of wheat sprouts, in particular to an atmospheric pressure dielectric barrier discharge plasma seed treatment device and method for improving the drought resistance of wheat sprouts. Background technique [0002] With the continuous warming of the global climate, the shortage of water resources and its uneven distribution in time and space around the world have caused serious water shortages in more than 80 countries including China. Drought has become the main limiting factor of agricultural production in the world. Wheat is the second largest grain crop in my country and plays an important role in agricultural production. The loess dryland in the Shaanxi-Gansu-Ningxia area is an important wheat producing area in my country, with great potential for increasing production. However, the climate in this area i...
