According to the production practice of the majority of farmers, it has been proved that the germination rate of vegetable seeds has a great relationship with the age of preservation. Different types of vegetables have different storage ages. Below the author on the shelf life of several common vegetable seeds. (1) Tomato: generally can be stored for 3-4 years, up to no more than 4 years, otherwise it will reduce the bud rate, a simple method to identify new and old seeds, mainly new hairy hair, and tomato flavor, old seeds skin hair hair Less (or shedding). (2) Cucumber: The maximum storage time is 2-3 years. Above this time limit, the germination rate is generally reduced by 20-30%. Even if it can emerge, some often have no true leaves after emergence and are not easy to survive. (3) Eggplant: Seeds with a shelf life of generally less than 6 years can be used. The new seeds are shiny and the old seeds are reduced in gloss according to the shelf life. (4) Pepper: It must not exceed 3 years, otherwise the germination rate will decrease, the germination rate will decrease by about 10% after 2 years of storage, and it will decrease by 30% after 3 years of storage. The new seeds will be golden yellow and the Chen seeds will be apricot yellow. (5) Onion Seeds: Vaccinated onions of summer species must be seeded with fresh seeds of the year. If old seeds are used, shallots will be seeded with moss seeds. Spring onions can use the seeds produced in the first year. (6) Celery: It can be stored for 3 years. The seeds of the end of the year cannot be used and must be stored for one year. (7) Amaranth: New seeds are good in the current year, and the germination rate is greatly reduced if stored for two years. (8) Cabbage: It can be stored for two years. The seeds that were harvested in that year can be sown in the same year. However, if it exceeds two years, the emergence rate will be reduced by 20-30%, and the resistance to disease will also be reduced. (9) Coriander: It must be stored for one year before use, but the storage time should not exceed 3 years, otherwise the flavor will be reduced.
