The latest propagation methods of Paeonia lactiflora

Paeonia lactiflora is a kind of herb, which is very popular in our country. It can be seen in many parks. In fact, peony is not only this ornamental value, but also has a certain edible and medicinal value. It is a kind of flower with high economic value, and there is also a special peony planting base in our country. However, many people do not know how to breed peony, the following editor brought the breeding method of peony, let's take a look at it!

1. Ramet propagation

Ramet propagation is the most common reproduction method in the propagation of Paeonia lactiflora, and it is mainly used on Paeonia lactiflora for medicinal purposes. The mother plant was dug up with soil in autumn and the budding peony head was selected for propagation. First, observe the peony head, pick out the peony head without buds and diseases and insect pests, and then cut the normal peony head into pieces. Each peony head needs to retain more than 2 strong buds, peony head should not be too thick and thin, then the main root is thin, the growth ability is not strong, and the bifurcation is reduced. If the peony head is too thin, the nutrition of the peony head is malabsorbed, and the growth is blocked after planting. However, the method of ramet propagation should not be used continuously, because peony should not be planted continuously, otherwise it will increase the morbidity, lead to poor growth and increase mortality.

2. Sowing and reproduction

Sowing and propagation is also a common method of propagation of peony. The seeds of peony are mainly inside the fruit. When the seeds are ripe, the fruit will crack and the seeds will fall out of the fruit. The ripening time of peony fruit will change according to the planting area, so we need to pay attention to it at this time. Seeds should not be stored for too long after harvest, and it is best to sow them immediately after harvest, because the water content of the seeds will gradually decrease with the sowing time. As a result, the germination rate of seeds decreased and it was difficult to take root and emerge seedlings. The poorly developed seeds should be selected before sowing, the dried seeds should be removed by the method of water immersion, and then soaked to accelerate germination, do a good job of soil preparation and fertilization, control the sowing density, and sow seeds in time according to weather changes.

3. Cuttage propagation

Although cutting propagation is not common, it is relatively simple. First of all, choose the soil with good ventilation and good drainage and irrigation as the cutting bed, soft soil. Then spread a layer of river sand on the soil as a cutting substrate and disinfect it before laying river sand to prevent diseases and insect pests from affecting growth. Then from June to August, the strong growing and pest-free branches were selected as cutting branches, and the cutting branches were about 12 cm long. Control the depth and timely cutting, pour enough water after cutting, cover the greenhouse, control the temperature of the greenhouse at 22 degrees and the humidity at about 85%, which can take root in about one month.

4. Root cutting propagation

The last method of propagation is root insertion propagation, and the premise of root insertion propagation is based on ramet propagation. When the plant is divided in autumn, the plant is treated with root cutting. after root cutting, the root cut of the plant should be disinfected to prevent the wound infection from causing diseases and insect pests. Then cut the broken root into a root section of about 8 li, control the density and insert it in the planting ditch, and the depth of the ditch should be controlled at about 12 cm. After inserting, cover with fine soil and pour enough water.

The above is a brief introduction of several propagation methods of Paeonia lactiflora, and the two most commonly used propagation methods of peony are ramet and sowing. Cuttings and root cuttings need certain techniques, because cutting is to ensure that the plant will not be hurt by another, and disinfection should be carried out after removal, so we must pay attention to the use of these two methods. That's all for today's introduction. This article is for reference only. Thank you for your reading and support.
