How to identify vegetable seeds
The skin color of the three onions, onion, and leeks are all black and their shapes are similar. If you don't look closely, it's hard to tell, but when you look closely, there are still differences between the three. Onion seeds are shield-like, angular, slightly flat, with few and neat skin wrinkles, and umbilicus with shallow sulcus. The seeds of the onion were shield-like and the skin was slightly irregular and wrinkled. The umbilicus was very deep. The leek seeds are shield-like, and the skin wrinkles are numerous and fine, and the umbilicus has no obvious concavity. In addition, on average, wolfberry seed weights range from 2.8 to 2.9 grams, onion seeds have a grain weight of 4.6 grams, and amaranth seeds have a grain weight of 4 to 4.15 grams. The scallion seeds are lighter and the onion seeds are heavier. . Third, the seed coats of these three vegetable seeds are poor in water permeability, water swelling is slow, soaking is required before sowing, and the life span of the three vegetable seeds is shorter.
