On April 18, 2025, the National Botanical Garden celebrated its third anniversary of its unveiling operation. The reporter learned from the National Botanical Garden today (April 18) that the main building of the National Plant Germplasm Resources Library located on the west side of the National Botanical Garden (North Park) is expected to be completed within the year and is scheduled to be trial operation by the end of 2026.

National Plant Germplasm Resource Library The total area of ​​the National Plant Germplasm Resource Library covers a total area of ​​60,000 square meters and has a total construction area of ​​11,000 square meters. It is the largest single germplasm resource library with the largest planned storage capacity in my country. According to the functional characteristics, the main body of the building is equipped with five major divisions: facility storage area, inventory preparation area, business research area, academic exchange area and science popularization display area. Among them, the facility storage areas include low-temperature storage, ultra-low-temperature storage, test tube seedlings, and genetic material storage libraries; the inventory preparation areas include seed pretreatment areas, genetic material treatment areas, test tube seedling treatment areas, etc. In order to ensure that the national plant germplasm resource library is put into operation as soon as possible after completion, the national plant germplasm resource library preparation library was completed and started operation at the end of last year.
