It is cold in nature, bitter and astringent in taste, and belongs to the liver and kidney meridians. It has the effects of clearing heat and detoxifying, inhibiting bacteria, nourishing the liver and kidney, cooling blood and stopping bleeding. Therefore, breeding and planting holly can not only beautify the environment, but also be used as a traditional Chinese medicine with certain economic value. In order to study the ecological adaptation mechanism of holly in arid environment and cultivate drought-resistant holly, the growth and physiological and biochemical characteristics of holly should be studied and analyzed through drought stress and rehydration treatment experiments.
