Now that the weather is getting warmer, growers are starting to buy seeds. Experts have reminded vegetable growers that vegetable seeds have a certain number of years of age. Some vegetable seeds must use new seeds. Therefore, new seeds must be identified when buying seeds to avoid affecting the yield and quality of vegetables.

Cabbage seed should use the new seeds of the year, and the seedling rate can be ensured. Seeds with two years or more can be used, the emergence rate is only 70% to 80%, and the disease resistance rate is low. The new seed used for the pepper seed is used in the same year, and the emergence of seeds for three or more years not only reduces the emergence rate, but also significantly reduces the yield. The new seed is golden yellow and the Chen seed is apricot yellow. If it turns brown, it cannot be used as a seed. Eggplant seeds can be preserved for 6 years, and new seeds can be used. If the seedling rate is lower than 6 years, it is better to use new seeds of the year. Celery seeds can be preserved for 5 years, but new seeds of the year cannot be used. Chen seeds must be grown after 1 year.

For coriander seeds, the new seeds of the year cannot be used. They must be stored for one year before they can be used, but the storage time should not exceed three years. Tomato seeds can be preserved for 4 years, and can be used within 4 years. If the seedlings grow more than 4 years, the seedlings will be reduced. The leek seeds must use new seeds of the current year, otherwise it is not easy to emerge. It is best to use new seeds for cucumber seeds in the current year. If it is more than 3 years, the emergence rate will be reduced by about 30%. The onion seeds are sown in summer and autumn. They must be seeded in the spring of the same year, otherwise seedlings will appear after the onion grows.
