What are the disinfection methods for potted vegetables?

Pour the seeds into warm water of about 50 °C while stirring (different vegetable seeds, the temperature is slightly different, please consult the botanist for the specific operating temperature), and continue to stir in the same direction for about 20-30 minutes, then make After the water temperature drops to room temperature, continue to soak for 3-4 hours to kill most of the pathogens on the surface of the seed.
Third, cultivate strong seedlings

In addition, keep the soil clean, remove weeds and fallen leaves in time, remove old leaves and diseased leaves, remove dead seedlings, and effectively reduce the source of pests and diseases.
Fourth, environmental regulation
For many vegetable diseases, high temperature and high humidity are favorable conditions for the disease, so plant on the closed balcony, avoid high temperature and high humidity! If the humidity or temperature is too high, the temperature can be high at noon, windless weather, proper window ventilation, To reduce the incidence of some diseases.
