Improve the level of scientific research to provide support for the development of plant protection
In addition to ex-situ plant conservation, the National Botanical Garden is also an important platform for plant scientific research in China. In the past year, the National Botanical Garden has continuously improved the level of plant scientific research and provided scientific and technological support for the development of plant protection.
The plant big data visualization system of the National Botanical Garden integrates the high-precision data of national macrobotany, and develops data products such as the national key protected wild plant information system, the early warning system of invasive alien plants, and the ex-situ conservation system of the National Botanical Garden, forming a comprehensive database of the whole temporal and spatial, multi-dimensional and full life cycle of species.
Sun Guofeng, Executive Director of the South Park of the National Botanical Garden: It vividly demonstrated the pattern of plant diversity in China, the distribution of endangered protected plants, the situation of alien invasion of plants, and the panorama of the four seasons of the National Botanical Garden, which strongly supported the work of the National Botanical Garden in the fields of plant diversity collection and research, ex situ conservation of endangered plants, and scientific communication.
The National Botanical Garden has a herbarium, the largest herbarium in Asia. In the past year, nearly 14,301 new plant specimens have been added, and the current collection of plant specimens has reached <>.<> million, ranking first among herbarium in Asia in terms of the number of specimens and overall scale of the collection.

Reporters from the main station visited the "treasure plants" of the National Botanical Garden
The National Botanical Garden is arguably a treasure trove of plants, covering almost all of the world's rare plants. So, what are the treasure star plants of the National Botanical Garden? Let's take a look
Troll taro, a rare and endangered plant in the world and one of the three flagship plants in the world's greenhouses, blooms in a rare number in artificial cultivation, and has only been opened more than 100 times in the world in the more than 100 years since its discovery. In July 2022, in the exhibition greenhouse of the North Park of the National Botanical Garden, the group flowering of troll taro in the artificial cultivation state was realized for the first time, and then it was successfully fruited, creating a new history of troll taro cultivation and research in China. Recently, the National Botanical Garden has come with good news, the fruits of this batch of troll taro have begun to germinate, which is also the first germination of China's self-cultivated troll taro.
The plant pictured above is called Chitose Orchid, just like its name, it can live more than 2000,<> years, native to the deserts of southern Africa, and is one of the most drought-tolerant plants in the world.
Cheng Yajing, senior engineer of the North Park of the National Botanical Garden: Chitose orchid existed on this earth more than 1 million years ago, it is a living fossil left by ancient times, and now, Chitose orchid has been sown and reproduced in our botanical garden, and we use seeds laid by our own pollination.
In the National Botanical Garden, there are nearly 1,000 rare and endangered plants such as troll taro and chitose orchid, which have become a beautiful and unique scenery of the National Botanical Garden with their unique shapes and unique characteristics.
