How does the plant factory breeding accelerator accelerate plant growth?

At the Urban Agriculture Research Institute of the National Chengdu Agricultural Technology Center, located in Sichuan Tianfu New Area, there is a plant factory plant breeding accelerator that can shorten the wheat growth cycle from over 100 days to just over 50 days, enable rice to be harvested quickly in about 60 days, and at the same time, lettuce's growth cycle averages only 34 days here.

Yang Qichang, a researcher at the Institute of Urban Agriculture, Chinese Academy of Agricultural Sciences and an academician of the International Eurasian Academy of Sciences, stated that in the future, relying on plant factories will provide new technical pathways for accelerated breeding and efficient cultivation of rice and other crops. The rapid propagation technology of plant factories has confirmed the feasibility of significantly shortening crop growth cycles and year-round continuous propagation, which can form a new crop breeding acceleration system coordinated with southern breeding, providing technical support for the modern breeding Industry.

How exactly is this achieved? Recently, the Chengdu Radio and Television Station's program "Amazing Beautiful Countryside" visited this plant factory to learn about crops such as wheat, rice, and corn, as well as various vegetables grown in the facility, and heard experts explain the secret behind significantly shortening crop growth cycles.
