Four propagation methods of peony flower

The reproduction methods of peony flowers can be divided into sexual reproduction and asexual reproduction. Sexual reproduction is also called seed reproduction, because peony seed reproduction takes three years to begin to blossom and seed, which takes a long time, so it is rarely used. Asexual reproduction includes plant division, grafting and cutting propagation, these three methods are more common.

Peony flower

1. Sow seeds. Peony seeds were harvested in time after maturing in early August and sown immediately. If you sow too late, the seeds should not germinate in spring. Sowing peony does not blossom until 5-6 years, so this method is generally only used when cultivating new varieties.

2. Ramet. It is a method of dividing a peony into several small peonies for planting. Ramets are mostly carried out during the period from "the Autumn Equinox" to "Cold Dew". When ramets, 4-5-year-old peonies can be dug up, removed the attached soil, and sunburned for 2 days, so that their roots lose water and become soft. split into several trees from the roots (Wuhua head) according to the natural growth potential, each tree needs to have some fine roots, and more plants with large plants and more buds can be divided, otherwise there will be less. After the ramet, the small trees should prune the old branches according to the number of buds on the "Wuhuatou". The old branches with 3 buds should be kept at 10 cm, and the old branches with 7 buds with 5 Mel should be kept at 5 Mel and 7 cm. Those with only one bud are not pruned. After pruning, the roots should be trimmed, the coarse roots and medium roots should be cut off (used as moutan processing and medicine), the small roots or fine roots are all left, and the small roots and fine roots can be left thick or uncut. If a diseased plant is found, it can be soaked in the root and planted.

3. Grafting. Grafting is a breeding of rare varieties or different colors on the same plant. The time of grafting can be between "the End of Heat" and "Cold Dew". Before and after the best period of "White Dew", the survival rate is 80%. The rootstock can choose paeony root and peony seedlings, and the scion should choose the one-year-old strong branch growing in the lower part of the plant, which is 10 cm long, with a robust terminal bud and 3 lateral buds of 2 Murra. the scion should be picked and used, and those that are not in use for the time being should be protected. The main varieties of scion are cinnabar base, Shengdan furnace, Zhao Fan, Zhuangyuan Hong, Yao Huang and so on. The methods of grafting are embedding or splicing. When the diameter of the rootstock is thick, it can be embedded, and when the thickness of the scion of the rootstock is similar, split grafting can be adopted. no matter which method, it is better to closely combine the scion with the cambium of the rootstock.

4. Cutting. Peony cuttings are not easy to take root, but it is important to master the appropriate time. During the period from "White Dew" to "the Autumn Equinox", the cut 3-year-old, disease-free and robust peony branches were inserted into the moist soil, and three new roots could grow in 15 days, with a length of 0.3ml 0.5cm. In 60 days, the new roots could grow to 3cm, and the number could reach 5MUR 7. In order to ensure higher survival rate, branches were treated with gibberellin (500 × 10) or naphthalene acetic acid solution (500 × 10) in the northern producing areas, and the effect was very good.

The cultivation method of how to plant peony flower

There are many flower-loving friends around us. Peony is one of our favorite varieties. How to plant peony? Next, let's tell you how to cultivate peonies.

1. Temperature and light

Sufficient sunlight is beneficial to the growth of peony, but it is not resistant to hot summer sun, and the plant will be dormant when the temperature is above 25 ℃. The suitable temperature for flowering is 17-20 ℃, but it must be treated with low temperature of 1-10 ℃ for 2-3 months before flowering. The minimum capacity is-30 ℃, but appropriate cold prevention measures should be taken in the northern cold zone in winter to avoid frost damage. The high temperature and humidity in the south is extremely disadvantageous to the growth of peonies, therefore, the cultivation of peonies in the south need to give them specific environmental conditions in order to enjoy the beautiful peony flowers.

2. Watering

Whether watering is proper or not is a key issue in the success or failure of potted peonies. After coming out of the house in early spring, apply fertilizer first, then pour water through, loosen the soil after water infiltration, and maintain the humidity of the basin soil until budding. If the pot is too dry, you can water it again until it blossoms. It is advisable to keep the basin soil moist in the future. On rainy days in summer, it is necessary to dump the stagnant water in the basin in time to prevent rotting roots.

3. Fertilization

Peony is a fertilizer-loving plant. In order to make the peony flowers big and colorful and avoid the phenomenon of "blooming every other year", we must pay attention to rational fertilization. The newly planted peony does not need to be fertilized within half a year, but can not be fertilized until half a year later. Generally speaking, fertilizer should be applied at least three times a year. The first time is "pre-flowering fertilizer", which is applied in combination with "thawing water" when the leaves and expenses are extended after the soil is thawed. For the second time, "post-anthesis fertilizer" was applied within half a month, and this fertilization played an important role in restoring plant growth and promoting flower bud differentiation. The third fertilizer was applied before the beginning of winter, and this fertilization played an important role in enhancing the growth in the coming spring. In the first and second fertilization, the fertilizer was made a living by quick-acting fertilizer, and the third fertilization was mainly based on slow-acting base fertilizer.

4. Pruning

In order to ensure the beautiful plant shape, luxuriant flowering and robust growth of peony, it also needs to be reshaped and pruned. Potted peony pruning can be divided into winter pruning and spring and summer pruning. In spring, the remaining buds of potted peony should be selected, the excess buds in the rhizosphere should be erased, the introverted branches, cross branches and heavy branches should be cut off, and the weak branches and excess branches should be removed to ensure that the plant shape is beautiful, ventilated and transparent. The residual flowers can be cut off in summer, and the diseased and dead branches can be cut off after falling leaves at the end of autumn.

5. Insect pests

The common disease of peony is brown spot, the leaves appear yellow-green spots at the beginning, and then gradually expand to form brown or black spots. Bordeaux liquid can be sprayed 1-2 times a month, if the condition is serious, it can be sprayed 3 times. The seriously infected leaves should be cut off and burned to prevent Cheyenne. There is also a kind of root rot that specifically harms the roots of peonies. The condition is that the roots blacken and rot, hindering growth, and serious ones can lead to the death of pruning. To prevent the disease, it is necessary to check carefully when planting ramets. If you find that there is a diseased root, you must cut off and burn it, and sprinkle some sulfur powder in the planting hole when planting. The common pest is cotton-blowing insect, which can be sprayed with 1500 times of omethoate emulsion and coated with stone-sulfur mixture in winter or early spring, which also has a good control effect.
