New seeds should be used in the root culture, and seeds from every other year cannot be used. Identifying new seeds can be done from the following aspects: (1) Look at the color of the new seed. The dark dark hair is shiny and shiny. The Chen seeds are gray and black, with white frost and dark. (2) Look at the seed stalk. The seed stalk is white and clear, and the stalk has no stalk or stalk that is yellow-brown. (3) Smell smell The new seeds have a relatively strong aroma of leek, and the Chen seeds are generally free of pungent aromas and have many other odors. (4) Different germination conditions After soaking, the new seeds germinate quickly, the buds are strong, and the seedlings are sown. Chen seeds have low germination rate and weak bud vigor. Most seedlings do not emerge after seeding or seedlings are weak after emergence.
