Except in cold and arid areas, it is cultivated in most parts of China. During artificial cultivation, try to provide an environment suitable for growth, and ensure that the soil is slightly wet, nutritious and suitable for light and temperature. In this environment, the growth state will be better.
Wormwood is widely distributed in China, Russian, Mongolian, Korean and Japanese. Mostly born in wasteland, roadside and hillside in low to medium altitude areas. There are many plants belonging to the same genus in the wild. They look very similar. People often confuse mugwort, mugwort, mugwort and mugwort, so they are also collectively called "mugwort".
Wormwood has strong adaptability to climate and soil, is cold-resistant and drought-tolerant, likes warm and humid climate, and grows well in moist and fertile soil. Artificial cultivation in hilly and low mountainous areas, the growth period is 24-30℃.
breeding method
1. Sowing: Seed propagation should be sowed in early spring, and direct seeding or seedling transplanting can be carried out in March-April. The line spacing of live broadcast should be 40-50 cm. After sowing, the soil should not be too thick, and it is advisable to cover the seeds with 0.5 cm. When the height of the seedlings is 10- 15cm, it shall be fixed according to the plant spacing of 20-30cm.
2. Plant segmentation: Artemisia argyi has strong tillering ability. Generally, 1 plant can tiller into several to dozens plants a year, which can be used as materials for plant division and reproduction. Therefore, the method of plant division propagation is mostly used in production, which is also the main propagation method of artificial cultivation.
In March-April every year, when the height of seedlings grown from rhizomes is 15-20cm, when the soil is wet, it is better to dig up the whole plant of wormwood and plant it according to the plant spacing of 45cm× 30cm. If there is no precipitation for 2-3 days after cultivation, it is necessary to drip water to preserve moisture.
