Germination period: soybeans can germinate and emerge about a week after sowing, and then the leaves will begin to stretch. Seedling stage: before the soybean grows into flower buds, the stems and leaves need to continue to grow. At this time, a lot of nutrients and water are needed to promote the growth of seedlings. It usually takes about a month to enter the flower bud differentiation stage.
Flower bud differentiation stage: when soybean enters the flower bud differentiation stage, the plant will grow the flower bud precursor, then the bud and bud grow, and the organ of the flower bud gradually grows. Flowering and pod setting period: At this stage, soybeans generally bloom in the morning, and the flowering period generally lasts for about a week. During this period, soybeans need more nutrients and water, and need to be watered and fertilized in time. Bulging stage: When entering the bulging stage, the beans in the pod will gradually expand.
About ten days after flowering, the growth rate of beans is slow, but after one month, beans will grow rapidly. Maturity: After the leaves turn yellow and fall off, the water content of beans in pods will also start to decrease, and soybeans will gradually mature at this time.
