What are the breeding methods of Paeonia lactiflora?

Paeonia lactiflora, also known as Shangli and Lizao, is a perennial herbaceous persistent root plant of Paeoniae Paeoniae, which is distributed all over China. It is one of the top ten famous flowers in China, and its flower shape is large and beautiful. What are the reproduction methods of Paeonia lactiflora?

I. split-plant propagation

Ramet propagation is the most common propagation method in the propagation of peony, and it is mainly used in the medicinal peony. The mother plant is dug up with soil in autumn, and the budded peony head is selected for propagation.

First of all, observe the peony head, pick out the peony head without buds and insect pests, and then cut the normal peony head into pieces, each peony head needs to retain more than 2 strong buds, the peony head should not be too thick and thin, the main root is thin, the growth ability is not strong, the bifurcation is reduced, if the peony head is too thin, the nutrition absorption of the peony head is poor.

Growth is blocked after planting, but 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 propagation

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 should pay attention to that the 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 seeds will gradually decrease with the sowing time, resulting in a decline in seed germination rate, making it difficult to take root and emergence.

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. Cutting propagation

Although cutting propagation is not common, it is relatively simple. First of all, the soil with good ventilation and good drainage and irrigation is selected as the cutting bed to soften the soil, and then a layer of river sand is laid on the soil as the cutting substrate. Disinfection should be done before laying river sand to prevent diseases and insect pests from affecting growth.

Select strong growing and pest-free branches as cutting branches from June to August, the length of cutting branches is about 12cm, control the depth and timely cutting, pour enough water after cutting, cover the greenhouse, control the temperature of the greenhouse at 22 degrees, humidity at about 85%, and take root in about one month.

4. Root cutting propagation

The last method of propagation is root insertion propagation, the premise of root insertion propagation is based on ramet propagation, the root cutting treatment of the plant is carried out in autumn, and the root mouth of the plant should be disinfected after root cutting to prevent wound infection from causing diseases and insect pests.

Then cut the broken root into the root segment around 8cm, control the density and insert it in the planting ditch, the depth of the ditch should be controlled at about 12cm, and then cover the fine soil and pour enough water.

The above is the introduction of the propagation mode of Paeonia lactiflora. The most commonly used propagation methods of Paeonia lactiflora are ramet and sowing. Cuttings and root cuttings need certain techniques, and attention should be paid to disinfection after removal.
