1. Hot-water soaking: Seeds that have been air-dried are placed in hot water at a temperature of 50°C to 55°C for 15 minutes, with continuous stirring to ensure even heating and maintain warmth. Once the water cools down, the seeds are removed and immediately transferred to cold water, where they are stirred continuously to cool them evenly. This process helps break seed dormancy and promotes faster germination.
2. Boiling water treatment: For seeds with thick seed coats, especially those from melon varieties, place them in a gauze bag and immerse them in water heated to 85°C to 100°C. Stir the seeds constantly to ensure even exposure to heat. After removing them, rinse immediately with cold water. Repeat this process 3 to 4 times. This method is effective in softening the seed coat and improving germination rates.
3. White wine soaking: Soak the seeds in a mixture of white wine and water in a ratio of 2:1:1 (white wine to water). First mix the white wine with water, then submerge the seeds for 10 minutes. Afterward, remove and allow the seeds to germinate. This technique enhances both the germination rate and germination potential of the seeds.
4. Potassium permanganate soaking: For medicinal herb seeds, start by soaking them in warm water at 50°C for 20 to 25 minutes. Then transfer them to a 1% potassium permanganate solution for 15 minutes. Afterward, rinse thoroughly with water to eliminate pathogens such as blight, anthracnose, and other fungal diseases.
5. Formalin soaking: Soak medicinal herb seeds in warm water at 30°C for 4 to 6 hours. Next, place them in a 1% formalin solution for 15 to 20 minutes. After removal, put the seeds in a container covered with a damp cloth and seal it for 2 to 3 hours. Finally, rinse with clean water. This method helps prevent diseases like blight, anthrax, and brown smut.
6. Seed powder dressing: Use powders such as carbendazim, thiram, or seed dressing spirit. The dosage should be 0.3% to 0.5% of the seed weight. Soak the seeds in warm water for 4 to 6 hours, then mix the powder into the seeds thoroughly after removing them from the water.
7. Bleaching powder slurry: Mix the seeds with a bleaching powder slurry at a concentration of 2% of the seed weight. Ensure the mixture is well combined and place it in a sealed container for 15 to 20 hours. This method is particularly effective in eliminating black rot fungus from seeds of plants like Radix isatidis and gentian.
8. Seed coating: Apply a seed coating agent containing a bactericidal compound to protect against various diseases in medicinal crops. Seed coating is currently one of the most effective methods for pre-sowing disinfection and also aids in preserving seedlings, preventing disease, and controlling pests after sowing. This technique improves overall crop health and yield.
