Abstract

The invention discloses a method for improving the germination rate of corn seeds. The method comprises the following steps that 1, corn which is free of damage of pests and diseases and plump in ear, and is not damaged and stored for one to three years is selected as seeds; 2, after the corn seeds are washed with sterile water three to five times, a sodium hypochlorite aqueous solution with the mass ratio concentration of one percent is used as sanitizer, the corn seeds are soaked for ten minutes, and the corn seeds are washed with clean water and dried after being taken out; 3, the corn seeds are washed with sterile water three to five times again and then poured into a nutrient solution to be put indoors to be soaked for one to two hours, filtering is carried out, and filter liquor is poured out; 4, after the seeds are soaked, the seeds can be sown immediately at proper time and be dehydrated for use. According to the method, the problem of the germination rate of the corn seeds due to incomplete disinfection and too long time is solved by disinfecting the corn seeds, the corn can germinate early, suffer from few diseases and be high in germination rate by soaking the corn seeds in the nutrient solution, the survival rate is high, operation is easy, and manufacturing cost is low.

Example Embodiment

[0017] Example 1
[0018] A method for improving the germination rate of corn seeds, comprising the following steps:
[0019] (1) Select corn that is free from pests and diseases, full of grains, and undamaged and preserved for 1 year as seeds;
[0020] (2) after rinsing the corn seeds with sterile water for 3 times, use a sodium hypochlorite aqueous solution with a mass ratio of 1% as a disinfectant, soak for 10 minutes, rinse with clean water after taking out, and drain;
[0021] (3) Rinse 3 times with sterile water again, put it in the nutrient solution and put it into the room to soak for 1 hour, filter and pour out the filtrate;
[0022] (4) The seeds can be sown immediately after soaking, or they can be dried for later use.
[0023] The formula of the nutrient solution is: 4 parts of glucose, 3 parts of potassium fulvic acid, 4 parts of trisodium phosphate, 5 parts of iron sulfate, and 1000 parts of purified water.
