Seed treater manufacturers take you to understand the heat treatment in the Seed treatment
Time of issue:
2021-09-15
Seed treater manufacturers tell you that the use of heat, that is, using a certain gap between the effective sterilization temperature and the temperature at which the seeds may be damaged, is used to selectively sterilize without causing damage to the seeds. Seed treater manufacturers tell you that this method can be divided into the hot water soaking method (moist heat) and the dry heat treatment method (dry heat). Among them, the hot water soaking method was applied earlier, but the dry heat treatment method had a better effect and less damage to plants.

Hot water soaking method: Seed treater manufacturers tell you that the difference in heat resistance between seeds and pathogens is mainly used to select appropriate water temperature and treatment time to kill the latent pathogens on the surface of the seeds and inside the seeds without causing damage to the seeds. . It can be divided into warm soup soaking method and hot water scalding method.
(1) Seed treater manufacturers tell you that the temperature of the water used for soaking seeds in warm soup is usually about 55℃, and the amount of water is 5~6 times the volume of the seeds. Specific operation: first soak the seeds in room temperature water for 15min, then transfer the seeds to 55~60℃ hot water for soaking, keep stirring, and keep the water temperature for 10~15min, then let the water temperature drop to 30℃, and continue soaking the seeds. When soaking seeds in warm soup, it is best to combine seed soaking with medicinal liquid, and the sterilization effect is better.
(2) Hot water blanching method: Seed treater manufacturers tell you that the principle of this method is similar to the soaking method in warm soup, and is generally used for seeds that are difficult to absorb water. Usually, the seeds should be fully dried, the amount of water should not exceed 5 times the amount of seeds, and the water temperature is generally 70~75℃, or even higher.
The above information is the Seed treater manufacturer's introduction and analysis of the heat treatment in the Seed treatment, hope it helps you.
