How many times a year does wormwood harvest? When is the harvest?
Artemisia argyi planted in the south can be harvested 4-5 times a year; Planting in the north can be harvested three times a year; The first harvest was in late April, and the last harvest was in late autumn. Wild wormwood is harvested in late April every year 1 time. Artificially planted wormwood should be applied with a certain amount of topdressing after each harvest. The topdressing is mainly composed of decomposed rare human and animal feces, with appropriate amount of phosphorus and potassium fertilizer. Keep the soil moist during production.

Artemisia argyi planting

1, select terrain.

Choose a place with flat terrain and good drainage. The middle of the border is high and the sides are low, like a "fish back".

2. Breeding mode

There are two ways to reproduce wormwood, one is sexual reproduction and the other is asexual reproduction. Sexual reproduction requires that the seeds should be treated before sowing, that is, the seeds should germinate in an artificially created environment before sowing.

Asexual reproduction is transplanting by digging new tubers from old wormwood. This propagation method grows fast, but care should be taken not to damage the main part when digging tubers.

3, timely fertilization

Before planting wormwood, you should lay the base fertilizer. You can use rotten fertilizer or animal manure, mix these fertilizers and turn them into the soil, and then furrow and ridge them for planting. After transplanting, the surviving wormwood needs to be fertilized in a large area after ten days. In order to improve the growth rate of wormwood, urea is generally used.

When the wormwood grows to 50 cm or 60 cm, it needs topdressing urea, and the fertilization method has changed from sowing to spraying in water. When the wormwood enters the dormant period after harvesting, it is necessary to apply some farmyard manure and organic fertilizer as base fertilizer to ensure safe wintering.

4. Irrigation methods

Use sprinkler irrigation when wormwood is short, and flood irrigation when wormwood grows to about one meter.

5. Planting density

The spacing between plants is 30 to 40 cm. Leave enough breeding space, promote photosynthesis and reduce the occurrence of pests and diseases.
