[0002] The seeds of high-quality agricultural products need to be selected. The specifications of the seeds directly affect the quality of the planted agricultural products. Seeds are a way of plant reproduction, containing immature germ and stored nutrients, and can germinate and grow into new plants under suitable conditions. Some agricultural products need seeds to germinate. In order to ensure the germination rate of the seeds, it is necessary to screen them.
