The weather is getting warmer and the farmers are ready to buy seeds. Guo Zhiqing, a researcher at the College of Horticulture of Northwest A&F University, reminded the majority of vegetable farmers that vegetable seeds have years of requirements. Some vegetable seeds must use new seeds. Therefore, when purchasing seeds, it is necessary to identify new ones and avoid affecting the yield and quality of vegetables. Guo Zhiqing said that cabbage seeds should use the new seeds of the year to ensure the emergence rate. With two or more years of seed, the emergence rate is only 70% to 80%, and the disease resistance rate is low. Pepper seeds should use the new seeds of the year, and the seedling rate of 3 or more years will not only decrease, but also the yield will drop sharply. The new seeds are golden yellow, and the old seeds are apricot yellow. If they become brown, they cannot be used as seeds. Eggplant seeds can be stored for 6 years, and new seeds can be used. If the seedling rate is reduced over 6 years, it is better to use the new seeds of the year. Celery seeds can be kept for 5 years, but the new seeds of the year cannot be used, and the seeds must be seeded one year later. For coriander seeds, the new seeds of the year cannot be used and must be stored for 1 year before they can be used, but the storage time should not exceed 3 years. Tomato seeds can be stored for 4 years and can be used within 4 years. If the seedling rate exceeds 4 years, the seedling rate will decrease. Amaranth seeds must use new seeds of the year, otherwise it is not easy to emerge. Cucumber seeds are best used in the new seeds of the year, if more than 3 years, the emergence rate is reduced by about 30%. Onion seeds should be used in summer and autumn, and seeds must be used in the spring. Otherwise, the onion will appear after growing up.
