What are the seed selection and seedling raising methods for willow wormwood?

When it comes to willow wormwood, many friends who have lived in the countryside for years are surely familiar with it. You can see it by rivers, on grasslands, and beside roads. Its stems and leaves are edible and rich in vitamins and minerals, and some farmers even plant it on purpose. So how do you select seeds for willow wormwood? What are the seedling raising methods? Below, the editor will tell you.

1. How do you select seeds for willow wormwood?

At present, willow wormwood does not yet have a truly approved variety. In production, there are only two farm production types. One is dry willow wormwood, whose stems are purple, with strong drought tolerance and strong cold resistance, and its sprouts have a slightly stronger wormwood flavor, slightly poorer quality, and relatively low yield; the other is water willow wormwood, whose stems are green, prefers moisture, and its sprouts have a lighter wormwood flavor, good quality, high yield, and slightly poorer cold resistance. Both types can carry out normal sprout production.

2. What are the seedling raising methods for willow wormwood?

1. Land preparation and bed making

Use plots from overwintering or spring vegetable crops, such as winter spinach, cabbage, water radish and other stubble. On the basis of heavy base fertilizer application to the previous crop, apply an additional 1000 kg of organic fertilizer per 667 sq m, then deep plow, harrow finely, level and make beds. The bed width is 0.8-1 m, and the length is unlimited.

2. Cutting

The cutting period is generally from mid-June to mid-July, lasting as long as one month. Select robust and uniform willow wormwood growing naturally in the wild, cut the whole plant back, and cut it into small sections of about 15 cm. The top of each cutting should have at least 1-2 plump buds. Insert the cuttings at a row spacing of 10 cm, plant spacing of 8 cm, and a depth of about 10 cm, watering while cutting.

3. Management

After cutting, water once a day to keep the bed surface moist and promote rooting and sprouting. Sprouting begins after one week. At this time, water according to the weather and soil moisture. Keep the soil alternating between dry and wet, watering about once every 7-10 days. When it grows to about 1 m, let it grow naturally.

3. Key points for growing willow wormwood

1. Soil

Willow wormwood is suitable for growing in fertile, weakly alkaline soil with a pH of about 7.5. It is best grown in riversides, shrub thickets, forest edges, roadsides, grassy meadows and the edges of marshy land in low and medium altitude areas.

2. Temperature

It is relatively heat tolerant, and around 25 degrees Celsius is most favorable for its growth and health. In winter, attention should be paid to heat preservation. It can be planted in greenhouses and plastic tunnels, with the temperature controlled not lower than 5 degrees Celsius.

3. Fertilization

Fertilize in a timely manner, and topdress along with watering. Organic fertilizer and farmyard manure can be used. Never use chemical fertilizer, to prevent soil compaction and poor aeration, which affect its growth.

4. Watering

It prefers a relatively moist environment. Before sowing seeds, the soil should be watered wet. After emergence, foliar spraying should be carried out frequently to prevent withering and death. It is not tolerant of waterlogging, so attention should be paid to drainage to prevent root rot and death.

5. Light

It needs sufficient light supply. When conditions allow, it is recommended to use a solar greenhouse for planting, which can achieve year-round cultivation.
