Method for treating germination of seeds

Abstract

The invention discloses a method for treating the germination of seeds. The method comprises the following steps of: firstly, preparing sodium sulfate electrolyte at the concentration of between 0.001 and 0.1mol / L, or uniformly mixing urea, NaBr(NaCl) and KBr in a molar ratio of 79 percent:19.5 percent:1.5 percent, controlling the temperature to be between 60 and 90 DEG C for dissolution, adding formamide or glycol in a volume which is equal to that of the mixture, and stirring and filtering to obtain ionic liquid electrolyte; secondly, disinfecting the seeds for 2 to 10 minutes by using 5 percent solution of sodium hypochlorite, putting the seeds into a diaphragm-free electrolyzer, adding the prepared sodium sulfate electrolyte or the ionic liquid electrolyte at the volume concentration of between 1 and 30 percent at the same time, and electrolyzing under the voltage of 1 to 10V at room temperature for 1 to 6 hours by taking titanium as a cathode and platinum as an anode and using a direct current or pulse electrolysis system; and finally, cleaning by using distilled water, performing microwave treatment, and drying. In the method, free radicals and microcurrent generated by an electrochemical system in situ are utilized to act on seed cells to ensure that the activity of enzyme inside the seed cells is strengthened, so that the germination of the seeds is promoted; and the germination percentage of the seeds is improved by 5 to 30 percent.

Description

technical field

[0001] The invention relates to a method for seed germination treatment, in particular to a method for improving seed germination rate by using electrochemical means to treat seeds. Background technique

[0002] The existing method for treating seeds mainly adopts some physical treatment methods, commonly used physical methods include electromagnetic field and electrostatic treatment methods, ultrasonic treatment methods, nuclear radiation treatment methods, magnetized water treatment methods, photon radiation and low-energy ion irradiation seed treatment methods Wait. However, it mainly uses high-voltage electric field treatment, such as: the invention patent of a "method for treating seeds with electrostatic field" with the publication number CN1031168A, which uses an electrostatic field to treat seeds to increase crop production. In this method, high voltage is required to treat seeds facilities, which are less secure and more expensive.
