What are the control methods for premature bolting in Angelica sinensis?
Based on the causes of premature bolting in Angelica sinensis, targeted measures can be taken to control it. The main measures are: starting from phase development, which is the primary condition for controlling qualitative phase changes. Starting from phase development, as long as the normal progress of qualitative change at either the vernalization stage or the photoperiod stage is controlled, premature bolting can be prevented. In production, controlling the vernalization stage is far easier than controlling the photoperiod stage. Since the vernalization stage can be controlled during winter seedling storage, when seedlings are relatively concentrated, it is convenient to carry out. That is, during seedling storage, first sterilize, control storage humidity at 6

How to prevent early bolting in Angelica sinensis? Detailed control methods
Angelica sinensis is native to high-cold mountain areas and is a low-temperature long-day plant. During its individual development, the transition from vegetative growth to reproductive growth requires passing through two developmental stages: the vernalization stage (requiring a low temperature of 0-5°C) and the photoperiod stage (requiring a long-day photoperiod of more than 12 hours). Therefore, artificial cultivation requires growing seedlings in the first year (raising seedlings), harvesting the roots for medicinal use in the second year, and collecting seeds from bolting, flowering and fruiting in the third year. However, in production practice, Angelica sinensis often bolts and flowers abundantly during June-July of the second year of cultivation, with the bolting rate in normal years ranging from 10-30%

What causes early bolting in Angelica sinensis?
Why does Angelica sinensis bolt early? Please explain the reasons. 1. Causes of early bolting in Angelica sinensis. 1.1 Seeds that are too plump, or seeds produced by early-bolting plants (commonly known as "gunpowder seeds", [flower] seeds or fire seeds) used for raising seedlings, are prone to early bolting after transplanting. According to the experience of herbal farmers, Angelica sinensis seedling cultivation has very strict requirements for seeds...
