The effective storage period of cabbage seeds is less than 2 years. The cabbage seeds harvested in the current year can be directly sown in the same year, and the seeds can still be planted in the second year. For seeds with a storage period of more than 2 years, the seedling rate after sowing should be reduced by about 20%, and it is highly susceptible to infection. The longer the storage time, the lower the emergence rate and the worse the disease resistance. Store cabbage seeds and store them in a cool and dry place. Do not store them in airtight containers such as water tanks or iron drums, so as not to damage the seeds and affect the emergence rate. The bright and shiny seeds are new seeds, and the dim is the Chen seeds.

Cabbage seed treatment method

1. Drying: In order to improve the germination potential of the seeds, the seeds can be dried for 2~3 days before sowing, 2~3 hours per day, and then placed in a cool place to dissipate heat after drying. This method can improve the vigor of seeds after long-term storage.

2. Warm soup soaking: In order to prevent seed bacteria, warm soup can be soaked. The specific method is to first soak the seeds in cold water for 10 minutes, then soak them in warm water of 50~54 °C for 30 minutes, then immediately transfer them to cold water for cooling, then remove them and put them in a ventilated place to dry.
