The latest propagation methods of Artemisia annua L.

Artemisia annua has high edible value as well as high medicinal value. It contains a large number of trace elements and nutrients needed by the human body, and has the effect of treating rheumatism and aiding digestion. Artemisia annua is planted in many areas, but our country is mainly in the middle and lower reaches of the Yangtze River. So what are the breeding methods of Artemisia annua? Let's take a look at how the editor introduces it.

1. Cuttage propagation

There are two kinds of cutting propagation of Artemisia annua, which are branch propagation and rhizome cutting propagation. Generally speaking, branch cutting propagation can not be carried out except when the temperature is low, and it can be planted at other times. Select sturdy branches, cut them into about 10 centimeters, then soak them with rooting powder for about four hours, and then cut them according to the row spacing of 20 to 25 centimeters and the plant spacing of 10 to 15 centimeters. And rhizome propagation is the use of underground rhizome, the old root disease root removal, select strong rhizome, and the rhizome will be divided into about ten centimeters, according to the fixed density can be cut.

2. Ramet propagation

Ramet propagation is generally after Ching Ming Festival every year, cut off the stems and leaves on the good ground, then dig out the Artemisia annua pier, and then divide the Artemisia annua pier into a single plant, and cut off all the old roots and wells on the single plant. Only part of the rhizome is left on each plant, and then it is planted according to the density of row spacing of 20 cm and plant spacing of 10 cm. In the planting method of split propagation, the survival rate is higher than that of cutting and striping, and the yield is also higher.

3. Striping propagation

The way of striping propagation is generally carried out before the plum rain, and the high-quality Artemisia annua plant should be selected, the older part of the aboveground part of the stem should be removed, and then a shallow trench with a depth of three or four centimeters should be set up in accordance with the prescribed spacing between rows and plants. Press the branches into the ditch, press the strips with soil, and water immediately to maintain more than ten degrees of the soil, which can promote the growth of new roots. Generally, new buds will be sent out in about 20 days, but because the development rate of the stem is different, the germination of new buds is not uniform, and the speed of plant growth is relatively slow.

4. Seed propagation

Seed propagation is the most basic and traditional planting method. Seeds should generally choose high-quality seeds with full grains and no diseases and insect pests. Under normal circumstances, the seeds are usually sown around April every year, but now the planting technology is more advanced, and now the planting in the greenhouse is more frequent, so it can also be planted during the period from the end of February to the beginning of March. Watering should be carried out after sowing to keep the soil moist, and seedlings will usually emerge in about ten days.

That's all the editor is going to introduce to you today. In fact, for the cultivation of Artemisia annua, the editor still thinks that the method of seed reproduction is still very good, followed by plant propagation is not suitable for large-scale planting, the economic benefits of small-area planting is still good.
