Embodiment

[0027] Zhengnong 7278 corn and Zhonglv No. 2 mung bean seeds were treated with 0.2% HgCl 2 Disinfect for 2 minutes, fully imbibition in distilled water after washing. Select uniform seeds and place them evenly in a petri dish. Place a piece of medium-speed filter paper at the bottom of the petri dish, add an appropriate amount of distilled water, and place them in a constant temperature incubator (27±0.2°C) for dark cultivation. Add distilled water regularly every day.

[0028] Place the dewy corn and mung bean seeds on figure 1 The two plates shown are treated in the direction of the field strength downward, 8h per day, and 5 days of continuous treatment. The direction of the electric field is downward, the electric field strength is 100KV / m, the pulse frequency is 1Hz, and the pulse width is 80ms. The same seeds were also taken as a control group and cultured under the same conditions, except that they were not treated with pulsed electric field, all conditions were the sam...

Abstract

The invention discloses a system using an extremely low frequency pulsed electric field to treat seeds, which comprises an extremely low frequency high voltage pulse generator, wherein a copper plate is respectively connected with two poles of the extremely low frequency high voltage pulse generator, the two copper plates are placed horizontally and serve as electrodes, and organic glass which is used for placing seeds is arranged between the two copper plates. A method which adopts the system to treat seeds includes the following steps: firstly, cleaning and sterilizing the seeds, killing surface microorganisms, and immersing the seeds in water for 3 to 24 hours; and then placing seeds which absorb water and germinate on the organic glass, and starting the extremely low frequency high voltage pulse generator to treat the seeds. According to the system using the extremely low frequency pulsed electric field to treat seeds and the treatment method, no pretreatment of seeds in any mode is required, only the extremely low frequency pulsed electric field is used for facilitating germination and growth of seeds, environmental pollution is avoided, nucleuses are not affected, chromosome variation of cells and environment hazards are avoided, the system and the method are simple and practical, and the effects are obvious.

Description

technical field [0001] The invention belongs to the technical field of low-frequency pulsed electric fields, and relates to a method for promoting seed germination and growth, in particular to a system for treating seeds with an extremely low-frequency pulsed electric field, and also relates to a method for treating seeds with the above-mentioned system. Background technique [0002] The treated plant seeds can improve seed vigor, promote seed germination and seedling growth, and increase seed stress resistance and yield. The existing seed treatment methods mainly contain chemical methods and physical methods. Chemical methods use various chemical reagents, hormones or drugs to treat seeds. In the invention patent of "Seed Treatment Agent for Promoting Seed Germination", gibberellin, naphthaleneacetic acid, zeatin and carbendazim are used to promote seed germination. Because the use of chemical agents in chemical methods will pollute the environment, physical methods have b...
