As we all know, the selection and breeding of new varieties is a long process. The traditional hybrid breeding is once a year. Even if the north is breeding and the south is breeding, it can only be harvested twice a year. It takes more than ten years to obtain a new hybrid. time. The fully enclosed environment of the plant factory can achieve precise control of temperature, humidity, and light. Plant growth is not restricted by external conditions. It can achieve annual continuous production, producing several or even dozens of generations a year, which greatly shortens the time of plant breeding. A truly well-deserved breeding accelerator.
