There is a great relationship between the germination rate of vegetables and the age of preservation, and the preservation period of different vegetables varies. Tomato: generally can be stored for 3-4 years, the longest is not more than 4 years, otherwise it will reduce the bud rate, the method of identifying new and old seeds, there is a new hair on the seeds, and there is tomato flavor, the old skin outer hair less hair or shedding. Cucumber: The maximum storage time is 2-3 years. Above this time, the germination rate will generally be reduced by 20-30%. Even if it can emerge, some of them will often have no true leaves after emergence and will not survive. Eggplant: Seeds with a shelf life of generally less than 6 years can be used. The new seeds are glossy and the old seeds are reduced in gloss according to the shelf life. Pepper: Can not exceed 3 years, otherwise the bud rate is reduced, the bud rate after storage for 2 years is reduced by about 10%, the storage is reduced by 30% for 3 years, the new seeds are golden yellow, and the Chen seeds are apricot yellow. Onion Seeds: Summer onion vaccination, you must use the seeds of the new hit that year, if you use the old seeds, shallot pumping moss seed. Spring onions can use the seeds produced in the first year. Parsley: Must be stored for one year before use, but do not store more than 3 years. Otherwise the scent becomes smaller. 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. Leek: New seeds are good in the year, if the rate of germination stored for two years is greatly reduced. Cabbage: It can be stored for two years. The seeds harvested that year can be sown in the same year, but if it is more than two years, the emergence rate is reduced by 20-30%, and the disease resistance is low.
