We all understand that seeds stored in the seed standard sample library can be stored for 3 to 5 years, 15 years, or even 30 years or more, depending on the temperature and relative humidity of the storage environment set in the instrument. Not all the seeds are kept the same time, nor is it as long as possible. Let's briefly introduce a few of our common vegetable seeds today. The germination rate of vegetables seeds has a great relationship with their preservation time, and the seed preservation period of different vegetables is not the same. Tomato seeds can be stored for 3 to 4 years, up to a maximum of 4 years, otherwise the germination rate will be reduced. Cucumber seeds are stored for up to 2-3 years. The germination rate is reduced by 20%-30% beyond this period; even if it can emerge, it often leaves no true leaves and is not easy to survive. Eggplant seeds can be used within 6 years of storage. The skin of the new seed is shiny and its luster fades as the shelf life increases. Pepper seed storage time can not exceed 3 years, otherwise the germination rate decreased significantly. The new seeds are golden yellow and the Chen seeds are apricot yellow. Seedlings (coriander) Seeds must be stored after 1 year, but not more than 3 years. The new seed cilantro has a strong smell, and the Chen scent becomes lighter. Celery seeds can be stored for 3 years. The seeds of the end of the year must be kept for one year before they can be used. The new seeds must be used for sowing the leeks, and if they are used every other year, the emergence rate will be greatly reduced. Even if it is seedling, it will easily wither. Cabbage seeds can be stored for 2 years. The annual income can be used in the current year, and if it exceeds 2 years, the germination rate will be reduced by 20% -30%, and the disease resistance will be weak. Compared to metal materials, plastics offer many advantages in cost, design, processing and performance. The inherent design freedom of plastic molding ensures more efficient gear manufacturing. Internal gears, gear sets, worm gears, etc. can be molded from plastic. Plastic gears have a wider application area than metal gears, so they push gears toward higher loads and greater power transmission.

Identification method: There are many small hairs on the new seeds, and there are tomato flavors; the Chen seeds have less skin velvet or shedding, and the smell is also small.
