Summary of Introduction and Domestication of Desert Plants in Gansu Minqin Desert Botanical Garden
There are 1704 species of vascular plants belonging to 484 genera and 82 families in the desert area of China.They not only play an important role in windbreak and sand fixation,improving the ecological environment,but also provide important living materials for human beings.They are valuable resources for maintaining ecological balance,economic and social sustainable development.In this paper,taking the first desert botanical garden-Minqin Desert Botanical Garden(MDBG)as an example,the introduction and domestication of desert plants were reviewed and summarized,and the future development direction was pointed out.MDBG has introduced 680 kinds of plant species,and successfully screened more than 10 kinds of excellent wind-proof and sand-fixing afforestation tree species such as Haloxylon ammodendron,Caragana korshinskii,Hedysarum scoparium,Elaeagnus angustifolia and Populus alba.The domestication,cultivation,and demonstration promotion of plant species such as Allium mongoli-cum Regel,Agriophyllum squarrosum,Pugionium axillatum,Cyperus esculentus,Cynomorium songaricum,Cistanche deserticola will further enrich the rural industrial structure.In the future,the introduction and domestication of plants in desert areas should be oriented to the needs of rural green development.Based on the important platform of the national forest germplasm resource bank of desert plants in Minqin Desert Control Station of Gansu Province,we should seize the opportunity of the construction of the national botanical garden,attach importance to the introduc-tion and domestication of wild desert herbaceous plant germplasm resources,and strengthen the cultivation of new varieties of desert wild forest and grass,so as to provide technical and industrial support for the rural revitalization of northwest China.
