Culture methods of four Seasons Peony

Peony is a perennial deciduous plant of the genus Paeoniaceae, with beautiful flowers, fragrant jade, elegant and elegant, magnificent, known as "king of flowers". In May 1985, it was ranked second among the top ten famous flowers in China. It is not only a flower loved by the Chinese people, but also cherished by people all over the world. Let's take a look at the breeding methods of peony in the four seasons.

Growth habits of four Seasons Peony

The peony of the four seasons likes warm, cool, dry, sunny environment, sunshine, semi-shade, cold, drought, weak alkali, stagnant water, heat and direct sun. it is suitable to grow in loose, deep, fertile, highly dry and well-drained neutral sandy loam soil, and grow poorly in acidic or clayey soil, but it is not resistant to summer sun exposure. When the temperature is above 25 ℃, the plant will be dormant, and the optimum 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 hot and humid weather in the south is extremely disadvantageous to the growth of peony, so the cultivation of peony in the south needs to give it specific environmental conditions in order to enjoy the beautiful peony flowers.

Propagation methods of four Seasons Peony

1. Ramet: the mother plant of peony ramet generally uses robust clumps. The mother plant for ramet propagation should retain the root tiller as far as possible, and all the roots on the new seedling should be retained so that the new seedling can grow for 5 years. This kind of seedling is easy to survive after planting, and the growth is more exuberant. The more roots are retained, the more prosperous the growth is.

2. Grafting: the grafting propagation of peony can be divided into two kinds according to the different rootstocks used, one is wild peony, the other is peony root. The common grafting methods of peony are embedding method, abdominal grafting method and bud grafting method.

3. Cutting: cut the cutting branches first, detach them from the mother plant and then insert them into the soil or other substrates to make them take root into new plants. The branches should choose the same year's soil buds issued from the roots of the peony, or when the peony is shaping and pruning, the branches with full terminal buds and no diseases and insect pests should be selected for panicle, with a length of 10 cm to 18 cm.

4. Sowing: before sowing, the soil must be carefully arranged and disinfected, the land should be ploughed and carefully cultivated, and sufficient base fertilizer should be applied. Then build a small bed 70 to 80 centimeters wide, hole sowing or strip sowing can be done. Sowing should not be too deep, with a degree of 3 to 4 centimeters, and the soil should be covered with a flat surface after sowing. Then gently stabilize the soil, and then pour water through.

5. Striping: peony striping is a propagation method based on the principle that branches can produce adventitious roots. The branches are overwhelmed or buried with soil on the plant without leaving the mother plant, the soil remains moist, the technical strip is buried to take root, and then cut off and planted to become a new plant, which is also a method of asexual reproduction of peony.

Culture methods of four Seasons Peony

1. Planting: the four seasons peony planting soil requires loose, fertile, neutral and slightly alkaline texture, cut off the broken and diseased roots of the planted peony seedlings, soak the insecticidal and fungicides into a prepared pot or pit, and stretch the root system. Fill the soil to the pot bowl or pit to gently lift and shake the seedlings, firmly seal the soil, and deep to the rhizome slightly lower than the basin or the horizon is appropriate.

2. Watering: the peonies of the four seasons are watered once after planting, and stagnant water is avoided, and water is watered as appropriate during the growing season. In arid areas of the north, water before flowering, water after flowering and frozen water are generally watered. In order to facilitate management, the residual flowers can be cut off and buried in the pot after flowering.

3. Fertilization: one year after planting, it is feasible to apply fertilizer in autumn, mainly mature organic fertilizer, combined with soil loosening, spreading and hole application. Chemical fertilizers are often used in spring and summer, combined with pre-flowering fertilizer and post-flowering fertilizer, and pot loading can be combined with watering liquid fertilizer.

4. Pruning: the peonies of the four seasons are planted in many rows in the same year, leave about 5 branches after germination in spring, erase the rest, concentrate nutrition, and make the flowers big and colorful in the second year. Autumn and winter, combined with Qingyuan, cut off the dry flower stalk, thin, non-flowering branches. When potting, trim it to your favorite shape as needed.

5. Middle ploughing: the growing season of peony in the four seasons should be ploughed in time, pull out weeds and pay attention to the occurrence of diseases and pests. In autumn and winter, ploughing is carried out on the sky blocks of more than two-year-old peony.

6. change the basin: when the four seasons peony grows for three or four years, it needs to be planted in a large pot or separate plant with new fertilizer soil in autumn.

7. Spraying: peony of four seasons sprayed stone-sulfur mixture before sprouting in early spring, and used the mixture of insecticides and fungicides in summer, once every 2 weeks depending on the condition. Combined with fertilization, chemical fertilizers and growth regulators should be added.

8. Reminding flowers: in order to increase festivals or celebrations, the peony can be heated about 50 days in advance, and the normal temperature is controlled at 10: 25 ℃, with an average of about 15 ℃ per day. Pay attention to keeping the plant moist in the early stage, ventilating and transparent after budding, and controlling the temperature according to the requirements of flowering stage after budding. Foliar fertilization should be applied at ordinary times to ensure adequate water supply. In this way, flowers can be seen at any time in winter and spring.
