Spring sowing came, some black dealers sold Chen seeds, and farmers could not tell Chen seeds, causing losses in production after purchase. How can we identify new and old seeds?
Generally, Chen seeds are stored for a long time, the seed color is dark, the embryo is hard, the keratin of the embryo is less, the silty is more, and it is easy to be smashed by the rice. The embryo often has fine round holes. When the hand reaches into the seed bag and draws out, there is a powder on the hand, and the bud potential and the bud rate are low. After sowing, the field has mostly appeared to have germinated in the soil, but the twisting does not expose the ground to form seedlings. The new seeds are bright, without wormholes, and have a high germination rate and germination potential.
