摘要
Tibetan medicine Lamiophlomis rotata(Benth.)Kudo is a plant belonging to the genus L.rotata(Benth.)in Labiatae,which is a commonly used bulk Tibetan medicine.As a first-class endangered Tibetan medicine,its sustainable utilization of resources is representative,and it is particularly important to master its species characteristics and adaptation mechanism under high Plateau adversity.This paper sorts out the habitat characteristics,morphological characteristics,population ecological characteristics,reproductive characteristics and other aspects of L.rotata(Benth.),analyzes the growth characteristics and adverse ecological factors of L.rotata(Benth.)in the Qinghai Tibet Plateau grassland,and analyzes its adaptation mechanism in drought,cold and different degraded grass from two aspects of biological characteristics and physiological characteristics.The author believes that it is necessary to study its stress resistance mechanism from many aspects,such as gene and molecular biology,and explore the suitable planting mode of monoculture,so as to provide a theoretical basis for introduction and domestication,cultivation management,resource protection and sustainable utilization.
