Embodiment 1
[0023] Embodiment one: high-altitude mountainous area (2400~3200 meters), slope plantation.
[0024] 1. Plant disease-resistant varieties: select plants with purple stems in the field to reserve seeds, and use the seeds of purple stem plants to raise seedlings for planting.
[0025] 2. Planting in high-altitude areas: choose areas above 2,400 meters above sea level to plant Angelica sinensis.
[0026] 3. Reasonable crop rotation: crop rotation with corn, white kidney beans, rapeseed and other crops is adopted in production, and the rotation period is required to be more than 3 years. Before planting Yun Angelica, the planting ground must be deeply plowed and sun-dried for more than 30 days to eliminate some pathogenic bacteria and insect eggs and inhibit the occurrence of diseases.
[0027] 4. Choose healthy seeds and seedlings: choose seeds without pests and diseases when raising seedlings; choose high-quality seedlings with no mechanical damage, few lateral roots, no diseas...
