Method for treating cotton seeds by utilizing action of electric field

[0031] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the present invention will be further explained in conjunction with the embodiments below.

[0032] A method for treating cotton seeds by electric field, including the following steps:

[0033] (1) Select cotton seeds, remove diseased seeds, shredded seeds, broken seeds, and small seeds, and plant them on a sunny day for 2 to 3 days. After drying, soak the cotton seeds in a velvet agent for 20 to 30 minutes. The centrifugal dryer spins it to dryness, and then puts it in a drum-type develling machine with drying function to remove the lint;

[0034] (2) The lint-free cotton seeds are placed in an ultrasonic cleaning tank for cleaning. The cleaning is divided into four stages. The first stage sets the ultrasonic frequency of 5-10kHz, the cleaning time is 5-8min, and the second stage sets the ultrasonic frequency of 10 ~15kHz, cleaning time 3~5min
