Angelica, as an important member of Chinese herbal medicine, has attracted much attention because of its rich medicinal value and unique growth conditions. In order to better understand the cultivation and growing conditions of Angelica sinensis, this article will elaborate on several aspects.
First, the growth environment.
Angelica sinensis grows in alpine meadows and shrublands at higher altitudes, and is usually more common in mountainous areas between 1500-3000 meters. When choosing a planting site, factors such as soil, climate, and altitude should be considered to ensure that Angelica is grown in a suitable environment.
2. Soil requirements.
Angelica sinensis has high requirements for soil, and the sandy loam soil with deep soil layer, loose and fertile, and good drainage is the best. During the planting process, it is necessary to pay attention to the pH of the soil to avoid excessive acidity or alkalinity affecting the growth of Angelica.

During the growth process, sufficient sunlight and water are required to meet the needs of Angelica sinensis for normal growth. At the same time, it is necessary to pay attention to prevent the impact of extreme weather such as frost and high temperature on the growth of Angelica.
Fourth, planting technology.
1.Seed selection and sowing.
Choosing healthy, plump seeds is the key to growing successfully. Before sowing, the seeds need to be disinfected to reduce the occurrence of pests and diseases. When sowing, it is necessary to ensure that the soil is loose and moist, which is conducive to the germination and growth of seeds.
2.Field management.
During the growth of Angelica, it is necessary to carry out cultivation and weeding, fertilization and irrigation in a timely manner. When fertilizing, organic fertilizers should be used mainly to avoid too much chemical fertilizer causing damage to the soil.

The processed Angelica herbs should be dry, free of impurities, and free of mildew to ensure their quality and efficacy.
In summary, in order to successfully plant and harvest high-quality angelica medicinal materials, it is necessary to comprehensively consider the growth environment, soil requirements, climatic conditions, planting technology and harvesting and processing. Only by mastering these points can we better cultivate and utilize this precious resource of Chinese medicinal materials. At the same time, in the actual planting process, it is also necessary to constantly sum up experience and improve technology to adapt to the changing environment and market conditions.
