Water absorption and swelling → germination → germination → radicle growth → hypocotyl elongation (on the market) → lateral roots appear (bean sprouts begin to age and lose commercial value) → the first pair of true leaves grow (aging and lose edible value) →

In the current bean sprout cultivation process, the growth degree of bacon is relatively low, and even radicle will not grow in the later stage, which is the performance of insufficient oxygen in bean sprout cultivation.
