There is a great relationship between the germination rate of vegetables and the years of storage. The variety of vegetables is different, and their shelf life is not the same.
1. The storage period of tomato seeds should not exceed 4 years, otherwise it will reduce the germination rate. Identification of new and old rapeseed methods: There are many small hairs on the new seeds, and there are tomato flavors; the old seeds have less velvet hair or shedding, and the smell is also small.
2, cucumber seeds can be stored for up to three years, beyond this limit its germination rate will be greatly reduced, even if some can emerge, it is not easy to survive.
3, eggplant seed storage time can be slightly longer, generally within 6 years of seed are available. The new seeds have shiny skin, but the gloss fades as the deposit period extends.
4. Store pepper seeds for no more than 3 years, otherwise the germination rate will decrease. Golden yellow is a new seed and apricot is a yellow seed.
5, celery seeds can be stored for three years, the seed can not be used that year, must be stored for 1 year before use.
6. The leek seed must use the new seeds of the current year. If the seedling rate is greatly reduced every other year, even if the seedlings emerge, they will wither.
7, cabbage seeds can be stored for 2 years. The seeds harvested that year can be sown in the same year, but the shelf life of more than 2 years, the emergence rate is generally reduced by 20-27%, and disease resistance becomes lower.
