Propagation methods of Artemisia annua L.

Artemisia quinoa has high edible value, but also has high medicinal value. It contains a large number of trace elements and nutrients required by the human body, and has the effect of treating rheumatism and helping digestion. Artemisia quinoa is planted in many areas, but China is still dominated by the middle and lower reaches of the Yangtze River. So what are the breeding methods of chenopodium quinoa? Let's see how the small series is introduced.

1. Cutting propagation

The cuttage propagation of Artemisia chenopodiana includes two kinds, branch cuttage propagation and rhizome cuttage propagation respectively. Branch propagation is generally not allowed except when the temperature is low, and other times can be planted. Choose stout branches, cut them into about ten centimeters, then soak them in rooting powder for about four hours, and then cut them according to the row spacing of twenty to twenty-five centimeters and the plant spacing of ten to fifteen centimeters. The rhizome propagation is to use underground rhizomes, remove the old roots and diseased roots, select thick rhizomes, and divide the rhizomes into about ten centimeters, and cut them according to fixed density.

2. Plant division and propagation

Plant division propagation is generally after the Qingming Festival every year, cut off the stems and leaves on the favorable ground, then dig out the chenopodium, divide the chenopodium into individual plants, cut off all the old roots and old wells on each individual plant, only part of the rhizomes need to be left on each individual plant, and then transplant according to the density of row spacing of 20 cm and plant spacing of 10 cm. The survival rate of the planting method of plant division propagation is higher than that of cutting and layering, and the yield is also higher.

3, layering propagation

The way of layering propagation is generally carried out before Meiyu, and high-quality Artemisia chenopodiana plants should be selected, the stems of the above-ground parts should be removed from the older parts, and then according to the prescribed row spacing and plant spacing, shallow grooves of three or four centimeters deep should be made, branches should be pressed into the grooves, layering with soil, and watering should be carried out immediately to maintain the soil more than ten degrees, so as to promote the growth of new roots. Generally, new buds will be issued in about 20 days, but because the development speed of stems is different, the germination of new buds is not uniform, and the growth speed of plants is relatively slow.

4. Seed reproduction

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

That's all I'm going to tell you today. In fact, for the planting of Artemisia chenopodiana, Xiaobian still thinks that the method of seed reproduction is very good, followed by that the propagation of divided plants is not suitable for large-area planting, and the economic benefits of small-area planting are still good.
