Propagation methods of Paeonia lactiflora

Peony is a kind of herbaceous plant, very popular in our country, in many parks can see peony shadow. In fact, peony not only has this ornamental value, but also has certain edible and medicinal value. Is a flower of high economic value, China now also has a special peony planting base. However, many people do not know how to breed peony, the following small series brought peony breeding methods, let's take a look!

1. Plant division and reproduction

Plant division propagation is the most common propagation method in peony propagation, and is mainly used for planting direction of medicinal peony. In autumn, the mother plant is dug out with soil, and the sprouted head is selected for reproduction. First observe the head, pick out the head without buds and pests, and then cut the normal head into pieces. More than 2 strong buds should be retained on each peony head. The peony head should not be too thick or too thin. If it is too thick, the taproot will be thin, the growth ability will not be strong, and the branching will be reduced. If it is too thin, the nutrition absorption of Shaotou is poor, and the growth is hindered after planting. However, it is not possible to continuously use the method of plant division propagation, because peony should not be continuous cropping, otherwise it will increase the incidence rate, lead to poor growth and increase mortality.

2. Seed breeding

The seeds of peony are mainly inside the fruit. When the seeds mature, the fruit will crack and the seeds will fall out of the fruit. The ripening time of peony fruit will vary according to the planting area, so everyone needs to pay attention to it. Seeds should not be stored too long after harvest, it is best to sow immediately after harvest, because the moisture content of seeds will gradually decrease with the increase of sowing time. The germination rate of seeds decreased and it was difficult to take root and emerge. Before sowing, the seeds with poor development should be selected, the dried seeds should be removed by soaking in water, then the seeds should be soaked and germinated, the soil preparation and fertilization should be done well, the sowing density should be controlled, and the seeds should be sown at the right time according to the weather change.

3. Cutting propagation

Although cuttage propagation is not common, but relatively simple, first choose ventilated sunny, good drainage soil as cuttage bed, soft soil. Then spread a layer of river sand on the soil as a cutting substrate, and disinfect it before spreading river sand to prevent diseases and insect pests from affecting growth. Then in June to August to choose strong growth, no pests and diseases of the branches as cuttings, cuttings about 12 cm long. Control the depth of timely cuttage, irrigation after insertion, cover the greenhouse, control the greenhouse temperature at 22 degrees, humidity control at about 85%, about a month time can take root.

4. Root cutting propagation

The last propagation method is root cutting propagation, the premise of root cutting propagation is to establish on ramet propagation. When the plants are divided in autumn, the roots of the plants are cut off, and after the roots are cut off, the roots of the plants are disinfected to prevent the wounds from being infected and causing diseases and insect pests. Then cut off the root into about 8 miles of root segments, control the density and insert them into the trenched planting ditch, and the depth of the ditch should be controlled at about 12 cm. Cover with fine soil after insertion and pour enough water.

The above is a brief introduction to several breeding methods of peony, peony is the most commonly used or sub-plant and sowing these two breeding methods. Cuttings and root cuttings need to have a certain technology, because when cutting, it is necessary to ensure that the plants will not be otherwise damaged, and after cutting, disinfection and other work, so we must pay attention to the use of these two methods. Today's introduction is here, this article is for reference only, thank you for reading and support.
