Introduction to Common Varieties of Artemisia selengensis and Detailed Explanation of Seedling Raising Methods

Artemisia selengensis was originally a wild plant growing by lakesides. Because of its unique taste and high nutritional value, it is now cultivated artificially. So how do you select seeds for artificially cultivating Artemisia selengensis? What specific varieties are there? And what seedling raising methods are there? Let us learn about it together.

What varieties of Artemisia selengensis are there?

1. White Artemisia selengensis

The tender stems of white Artemisia selengensis are pale green, thick and juicy, crisp and tender, and not easy to age. The leaf color is slightly lighter, and the leaf surface is yellow-green. It sprouts earlier in spring, has more edible parts, and has a relatively high yield, but its fragrance is not strong.

2. Green Artemisia selengensis

Green Artemisia selengensis has green stems and a fragrant taste. According to leaf type, it belongs to the broken-leaf Artemisia selengensis. Its main characteristics are mid-season maturity, high yield, dark green tender stems, and a slightly stronger fragrance. The edible tender stems mainly grow from the underground part after the stems are cut from Yuan to April.

3. Red Artemisia selengensis

When the tender stems of red Artemisia selengensis first sprout, they are green or light purple. As the stems grow, the color deepens, and the tender stems eventually become light purple or purplish red. The stems have more fiber, are easy to age, and the leaf color is darker. It sprouts later in spring, has fewer edible parts, and has a relatively low yield, but its fragrance is stronger.

What seedling raising methods are there for Artemisia selengensis?

1. Cutting propagation for seedling raising

At the end of April and the beginning of May, dig out its aboveground stems, remove the middle and lower leaves, cut them into 10-15 cm cuttings, and insert them into the seedling shed at a density of 5 cm plant spacing and 10 cm row spacing. The insertion depth should preferably be such that two-thirds of the cutting enters the soil. About 200 seedlings are inserted per sq m of seedling land. After insertion, strengthen fertilizer and water management to promote vigorous plant growth and obtain robust seed stems.

2. Land preparation and fertilization

Choose sandy soil with convenient drainage and irrigation and fertile texture for cultivation. Apply 4000-5000 kg of decomposed farmyard manure, 25 kg of ammonium bicarbonate, 25 kg of potassium chloride, and 25 kg of superphosphate per mu, or 100 kg of cake fertilizer and 50 kg of high-content compound fertilizer as base fertilizer. After application, plow deeply, harrow finely, and level. Open beds at 1.2 m including ditches, with a bed surface width of 1 m, and make high beds to facilitate field management, drainage and waterlogging prevention, and furrow irrigation for drought resistance.

3. Timely planting

The end of June and the beginning of July are generally the rainy season. Cuttings are prone to rooting and sprouting, making this a good period for cutting transplanting. Pull up the Artemisia selengensis in the nursery with roots, cut off the underground stems, pinch off the tender tips, remove the leaves, and cut them into 10-15 cm cuttings. Open furrows and plant them by cutting. Use 5 cm plant spacing and 10 cm row spacing. The planting depth should preferably be such that two-thirds of the cutting enters the soil. After insertion, water once thoroughly.

4. Field management

After the cuttings root, apply topdressing 1-2 times, using 15 kg of urea per mu each time, and irrigate immediately after topdressing. Wild Artemisia selengensis has wide adaptability and strong stress resistance, and generally has no pest or disease damage. If in hot and rainy seasons or under poor ventilation, it is susceptible to powdery mildew; for protected cultivation, pay attention to preventing gray mold, and use carbendazim and chlorothalonil for spray control.

5. Layered harvesting

March to April is the peak growth period for aboveground stems. When the Artemisia selengensis stems are about 20 cm high, cut them with a sharp knife 3-4 cm above the ground, leave a few heart leaves at the top section, and remove all other leaves. After rinsing clean, tie them into bundles in fixed quantities, stack them in a cool place, cover with a wet cloth, and after about half a day of softening, they can be sold. From late October to February of the following year, use an iron shovel or nail rake to dig out the underground stems, wash the soil off the rhizomes, and they can be sold on the market.

Artemisia selengensis is a wild plant of the Asteraceae family, and is a wild vegetable whose roots and tender stems are used for food. In recent years, due to continuously increasing domestic consumption, wild Artemisia selengensis has been in short supply. Therefore, artificial cultivation of Artemisia selengensis has arisen in some places and achieved objective economic benefits, making it a good rural project for becoming prosperous.
