Growth process of peony

Cultivation method of peony-peony 1, cultivation method and place of peony:

Peony prefers sunny places to hot and humid places. Peony likes cool places. Just pile about 30 cm of soil in the lowlands.

Use soil:

Peony can generally be cultivated as long as it is not extremely sandy or excessively sticky soil. Beneath the fertile topsoil is the most ideal soil, containing a small amount of clay. Preferably slightly acidic soil. Well-drained and less dry soil is more conducive to the growth of peony. Too thick soil should be mixed with appropriate amount of sand. Excessive sand should be mixed with appropriate amount of ordinary soil. 2. Planting method:

It can be used for both ground cultivation and potted plants. As far as potted plants are concerned, they should be transplanted every three years. (The period is between 10 and 1 month) The ideal flowerpot has a diameter of more than 30 cm, and the depth and diameter are roughly the same. Garden soil should be mixed with rotten leaves or chicken manure, and then mixed with a handful of oil powder or bone powder. It is very important to use cylindrical soil or sand mixed in subsoil to promote drainage. Grafting buds should be buried under the soil layer. When you plant a pot, put it where you want after planting it, and then water it when the soil in the pot is dry. See figure 1 for ground cultivation. 3. Fertilizer:

Peony needs a lot of fertilizer, but be careful not to apply too much fertilizer, and it should be slightly effective and long-lasting. The fertilizer can be slow-acting residual fertilizer such as oil meal or bone meal. The fertilization period is 2-3 months; Apply ritual fertilizer after flowering in May-June; 10- 1 1 autumn fertilization. No fertilizer will be applied from July to September. 4, disinfection:

Distribute 600 times of Dixon water mixture in early April, 500 times of Dixon water mixture and 2500 times of Benret water mixture in early May; Distribute Dixintong 400 times solution in June-July. For pests, spray 800- 1000 times of fenitrothion or 1000 times of trichlorfon. Disinfect for 2-3 times from early April to early July.

Benomyl: Fungicide, also known as Benomyl, heterocyclic fungicide. Carbendazim and thiophanate methyl can be used instead.

The above agents can be replaced by carbendazim, thiophanate-methyl and mancozeb. Please refer to the drug instructions for specific dosage.

After the leaves of Paeonia suffruticosa were unfolded in the early stage, leaf protection was the main method, and foliar fertilizer was applied, with a slightly lower concentration.

Application after flowering: sterilization is the main method, and bactericide and foliar fertilizer are applied at normal concentration. 5, cut:

Although the stem of peony is slender and looks unstable, it can produce large flowers, which is somewhat unbalanced. Because of this, the most important thing is pruning. 2-3-year-old seedlings need pruning in September, leaving only 1-2 buds at the bottom, and all other upper flower buds are cut off. After planting, the seedlings are only 1-2 years old, and the remaining flower buds should be covered with soil for 3-4 cm. In this way, the roots of peony will be born from flower buds, and the roots of these peonies will continue to grow and enrich, and the branches of flower seedlings will gradually become thicker. Beautiful flowers bloom every year. When pruning, you should consider cutting the plant shape into an inverted cone. Weak branches and buds, or inward-growing buds, and flower buds growing on dead branches should be cut off. Flowers that didn't bloom in those years, but grew well, should be preserved until next year. 6, breeding methods:

The flower buds of peony are generally grafted on the roots of peony, and the propagation method of ramets or seedlings can also be used. In China, the roots of peony are often used as rootstocks for grafting. The picture shows one-year-old grafted seedlings. Branch age and flower seedling age:

Branches can be many years old, but after grafting, the seedling age is calculated according to the grafting time.

1 seedling was grafted last September, and this September 1 year old.

Graft 2-3 seedlings the year before last or September the year before last, and they will be born for 2-3 years in September this year.

Generally, grafted seedlings will grow 1 many new branches every year. 9, suitable for planting peony area

No matter where you are, please make sure that your area meets the following conditions:

In winter, the ground temperature is below 4 degrees Celsius for more than 35 days, so a long enough low temperature period can make the roots develop well before flowering. Please check the ground temperature in winter at the local meteorological bureau or related websites.

Ground temperature: 5 cm-10 cm below the ground. 10, peony transplanting time:

Lunar solar terms: You can transplant rice seedlings from the autumnal equinox to the millennium. It means that normal transplanting requires the ground temperature to be lower than 25 degrees.

For the south, during the autumnal equinox to the Millennium, the ground temperature in some areas may drop less than 25 degrees, but in the main peony planting areas, peony will start to grow new roots after the Millennium, and replanting peony may have damaged roots.

Therefore, it is best to transplant southern peony between the autumnal equinox and the Millennium. Please water it once after transplanting and cover it with black gauze. 1 1, planting soil:

Loam silt is the best (not river sand, but coarse sand), and a proper proportion of mixed soil can also be used.

The soil is slightly alkaline/acidic, and the color will be slightly different with different pH values.

When planting, ensure that 0.5 meters below the ground is good soil. 12, planting peony

Within three years of planting peony, the underground part mainly increased the number of roots, but most of them were fine roots. So in this period, raising roots is the most important task. When flowering, 2-3 seedlings will have 1-2 flowers, and 1 seedling will have at most 1 flower. Don't pinch the bud. Too many flowers in this period are likely to cause your peony to hang up.

From the fourth year of colonization, the main reason is that the stems become thicker.

After 7 years of planting, the growth of rhizomes is gradually slow and can be differentiated into plants.

Please don't change the pot frequently. Please change the cauldron every three years instead of 1-2 times a year.

When changing pots, please change them in the autumn transplanting season of September-June, 65438+1October, cut off your plastic pots or clay pots and transplant them all with original soil.

Don't shake the soil off the roots before replanting. 13, watering:

It rains in spring, so you can't water it.

In spring drought: it is best to ditch and water between rows to let water naturally penetrate from both sides. Don't water the flower seedlings a lot. 14, planting depth and spacing:

The planting hole is 20-30 cm wide and 40-50 cm deep.

Plant a peony or peony in an area of 80*80 cm or 60*60 cm, with a minimum of 40*40 cm.

Peony is a deep-rooted plant, which needs a lot of nutrition supply. Please ensure that no other crops grow within the following plant spacing and weed them in time. Appropriate shading in summer.

In summer, vines can be planted at the edge of the flower pond or other places for shade, but the height of vines must be high enough. Under the premise of sun protection, ventilation must be provided to prevent common diseases in summer. 17, planting error analysis-1.

Error:

(1) Too much shelter, no ventilation, easy to get sick, easy to fall leaves early, leading to autumn hair and weak plants.

(2) Too many other crops affect the nutritional supply of peony.

Peony is a deep-rooted plant and needs more nutrition. In addition to proper fertilization, please ensure that no other crops grow within at least 60*60 cm.

(3) The soil is too wet and watered too much.

Peony root is a fleshy root, which is easy to rot when watered too much. The peony in this picture needs to be covered with a mound of 15-20cm to improve the terrain and slow down the trend of crisp autumn air.
