The growth process of broad bean

Broad bean is native to the coast of Europe and the Mediterranean, southwest Asia and North Africa. Legend has it that Zhang Qian in the Western Han Dynasty was introduced into the Central Plains in the Western Han Dynasty and can be planted in most provinces of the country. It is mainly planted in autumn and winter in the south of the Yangtze River and early spring in the north of the Yangtze River. Let's take a look at the growth process of broad bean.

Germination and seedling stage

The germination and seedling stage of broad bean is about 11-30 days, from the radicle breaking through the seed coat to the main stem (bud) extending 2-3 cm from the ground.

Seedling growth period

The seedling growth period of broad bean has more than 90 days, during which the main stem elongates upward, branches continue to form, and flower buds begin to appear after flower bud differentiation.

Budding stage

The budding period of Vicia faba was 35-40 days, and the first flower cluster in the lower part of the autonomous stem or branch began to bud to flower. at this stage, the roots, stems and leaves of Vicia faba grew vigorously, the early branches began to bud, and a large number of branches formed in the later stage. it is shown that vegetative growth and reproductive growth are carried out simultaneously, and it is also a period of branch formation.

Flowering and podding stage

The flowering and podding period of Vicia faba is 60-65 days, the period from flowering and podding to the natural shedding of leaves is the flowering period, and about 7 days after flowering is the period of rapid vegetative growth and a large number of flowering and podding in Vicia faba's life. from the beginning of grain filling to the natural shedding of leaves, with the gradual cessation of vegetative growth, filling accelerated and there was a filling peak.

Seed maturation period

After 10-20 days, the leaves fall off naturally, the pods and seeds grow long until the pod shell turns dark brown, and the seeds lose water gradually.
