Problems solved by technology

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

Embodiment approach 1

[0016] Implement the method for a kind of seed germination treatment of the present invention, its specific implementation method is as follows:

[0017] First, prepare the electrolyte, configure 6×10 -2 mol / L sodium sulfate electrolyte, weigh 1.704g of anhydrous sodium sulfate solids, and put it in a 200mL volumetric flask for the treatment of soybean seeds;

[0018] Secondly, carry out the treatment of seeds, select 50 soybean seeds in the bean seeds, first use 5% sodium hypochlorite solution to disinfect the seeds for about 8 minutes; In the sodium sulfate electrolyte of the above configuration, the titanium rod material is set as the cathode, and the platinum wire material is used as the anode, and a DC power supply is selected under the electrolysis system of DC, and at room temperature, the selected voltage is about 6V, and the soybean seeds are electrolyzed After about 4 hours, the electrochemical system is used to act on the seeds through the active free radicals gene...

Embodiment approach 2

[0020] First, when configuring the electrolyte, weigh 189.6g of urea, 80g of NaBr, and 7.2g of KBr according to the molar ratio of urea: NaBr: KBr=79%: 19.5%: 1.5%, mix them uniformly, heat, and control the temperature Dissolve it completely at about 85°C to obtain 200mL of a colorless solution, then add an equal volume of formamide, stir evenly, and filter to obtain an ionic liquid electrolyte, put it in a container and seal it for later use, and then measure 3mL The ionic liquid is fixed in a volumetric flask of 100mL to obtain an ionic liquid electrolyte with a volume fraction of 3%, which is used for the treatment of soybean seeds;

[0021] Secondly, carry out the treatment of seeds, select 50 soybean seeds in the bean seeds, and carry out disinfection treatment with 5% sodium hypochlorite solution for about 8 minutes; In the ionic liquid electrolyte whose volume fraction is 3%; the titanium plate material is set as the cathode, the platinum plate material is the anode, an...

Embodiment approach 3

[0023] First, prepare the electrolyte, configure 2×10 -2 The sodium sulfate electrolyte of mol / L, take by weighing 0.568g anhydrous sodium sulfate solid, be contained in the volumetric flask of 200mL, be used as the processing to cabbage seed;

[0024] Secondly, carry out the treatment of seeds, select 50 cabbage seeds in the vegetable seeds, first use 5% sodium hypochlorite solution to disinfect its seeds for about 8 minutes; In the sodium sulfate electrolyte of the above configuration, the titanium rod material is set as the cathode, and the platinum wire material is used as the anode, and a DC power supply is selected and under the electrolysis system of DC, and at room temperature, the selected voltage is about 4V, and the cabbage seeds are electrolyzed After about 3 hours, use the electrochemical system to act on the seeds through the active free radicals generated in situ and the microcurrent with the cells, and finally wash the seeds with distilled water for about 3 tim...

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. [0003] Existin...
