What are the growth cycles of peony flowers and what are its growth characteristics

Now we plant peony is mostly a hybrid of purple peony and Jishan peony, peony is an important ornamental plant, is China's top ten famous flowers.

One. Peony was once regarded as China's national flower and was known as the "king of flowers". Because of its large and fragrant flowers, it is also known as "the national color and natural fragrance". It is a rare and precious flower endemic to China. It is native to the West Qinling Mountains and Daba Mountain.

Mountain area. It has thousands of years of natural growth and more than 1,500 years of artificial cultivation. It has been introduced all over the world.

The growth cycle of peony mainly goes through four stages: budding stage and flower buds.

period, flowering and defoliation. Generally, under a good environment and normal cultivation management, the lifespan of peony can reach 100 or hundreds of years. Let's take a look at the characteristics of the growth cycle of peony.

1. Peony germination stage.

Every year in mid-February, when the temperature begins to warm, the buds of the peony will begin to absorb water and then continue to expand, gradually cracking, and finally revealing flower buds.

2. Peony bud stage.

At the end of February and the beginning of March, when the temperature rises even higher, the buds of the peony buds are completely cracked, and the top of the flower bud or half of the flower bud can be seen.

3. The flowering period and growth period of peony.

Peonies generally bloom in mid to late April, when the buds are in full bloom. The flowering time of different varieties is different, which can vary by about 6-10 days, and the entire flowering period of most peonies can reach nearly 1 month. After the peony flowers wither in early May, the leaves enter the rapid growth period, the growth rate accelerates, and they become larger and thicker.

4. Peony defoliation period.

From late October to early November, the peony leaves gradually turn yellow and gradually fall off. After the defoliation period is over, the peony will enter a relatively dormant period. At this time, the surface of the peony has stopped growing, but there is still physiological activity inside, because the peony needs to store enough nutrients to ensure the normal growth and development of the peony plant in the coming year.

According to the above specific introduction, we can know that the growth cycle of peony is not long, and the flowering period of peony is relatively short compared to other flowers, which only lasts about a month, which is fleeting. Then we need to give better management to peony when planting it to ensure that peony can grow and develop well, and at the same time, it can also keep it for a longer flowering period and have stronger ornamentality.

The growth cycle goes through four stages: childhood, youth, adulthood and old age. When the temperature is lower than 4, the roots of peony are in a semi-dormant state and the growth is stagnant.

There are budding stage, flower bud stage, flowering stage and defoliation stage; The lifespan of peony flowers is relatively long, and when the temperature is low, the roots of peony are in a semi-dormant state and their growth is stagnant.

Peony flowers can live up to 100 years, one to three years for seedlings, 4 to 40 years for the young period, and more than 40 years for the old plant. Peonies generally bloom vigorously after 4-5 years of planting, and are relatively slow before.

Glad to answer your questions Planting Choose a sunny place without standing water, preferably on a sunny slope, on a fertile, well-drained sandy loam. Before planting, turn the land deeply, the planting pit should be appropriately large, and the roots of the peony should be vertically stretched into its hole, and the roots of the fist should not be fisted. Do not plant too deep, preferably just bury the roots.

There are fewer potted plants.

Light and temperature Sufficient sunlight is good for its growth, but it is not tolerant to summer sun exposure, and temperatures above 25 will make the plant dormant. The suitable temperature for flowering is 17 -20, but it must be treated at a low temperature of 1 -10 for 2 -3 months before flowering. The minimum temperature tolerance is -30, but the cold regions in the north need to take appropriate cold protection measures in winter to avoid frost damage.

The high temperature and high humidity weather in the south is extremely unfavorable to the growth of peonies, so the cultivation of peonies in the south needs to give them specific environmental conditions to enjoy the beautiful peony flowers.

Watering & Fertilizing Water 2 times before planting. Fill with water once before winter to ensure its safe wintering. After the beginning of spring, water according to the dry and wet conditions of the soil, but do not overwater.

Fertilizer is generally applied 3 times a year, the first time is pre-flowering fertilizer, and fast-acting fertilizer is applied to promote its flowering and blooming. The second time is post-flowering fertilizer, and the first time is organic liquid fertilizer. The 3rd time is autumn and winter fertilizer, mainly basal fertilizer, to promote the growth of the following spring.

In addition, it is necessary to pay attention to cultivating and weeding, and there are no weeds to gently cultivate the loose soil.

Plastic pruning After the flowers are gone, pick the flowers and prune them in time, and cut them according to the natural growth of the tree shape combined with the desired tree shape. If you want the plant to be low and the flowers are dense, it is necessary to shorten and weigh more to inhibit the growth of branches and the occurrence of root tillering, and it is generally advisable to retain 5-6 branches per plant.

Flowering control potted peony can be treated by winter flowering and flowering in the Spring Festival, the method is to select strong peony varieties with full scale buds (such as Zhao Fen, Luoyang Hong, Shengdan furnace, Ge Jinzi, Zhu Shalei, Dazi Hu Hong, Mo Kui, Oolong Tousheng, etc.) with soil, try to hurt the roots as little as possible, dry in the shade for 12-3 days and then pot, and carry out plastic pruning, each plant leaves 10 top buds full branches, leave the top buds, and the rest of the buds are erased. When potting, the size of the pot should match the plant to achieve a satisfactory plant shape. After watering thoroughly, manage normally.

50-60 days before the Spring Festival, move it into a greenhouse about 10 spray water 2-3 times a day, and keep the basin moist. When the scale buds are expanded, gradually warmed to 25-30, and the night temperature is not lower than 15, so that flowers can be seen in the Spring Festival. Have a nice day.

The growth process of peony flowers: In spring, when the temperature exceeds three degrees, the peony begins to sprout, and the tip gradually cracks, revealing the tips of the teeth and leaves. Leaf buds extract leaves and stems when they are above 60 degrees Celsius.

Flower buds usually begin to differentiate between the end of April and the beginning of May, and form between September and November. After flowering, the flower buds continue to differentiate in the leaf axils.

The growth period of peony flowers and the change of seasons are related. In spring, after the temperature rises, the buds will begin to germinate, leaf buds or flower buds appear, as the temperature rises, the leaf buds begin to grow stems and leaves, the flower buds pull out the flower stems, the flower stems will grow leaves and flowers, and the flower buds can be re-differentiated after the flower is gone.

The differentiation of flower buds is very important, because it is related to the flowering of peony flowers, and it usually takes a long time for the differentiation of flower buds to be differentiated during the growth of peony flowers. Generally speaking, it takes three months for the flower buds of a single-petaled peony flower to be differentiated, and it is generally completed from late August to early September. For double-petaled peony flowers, the flower bud differentiation time is longer, generally it takes three and a half months, and the flower bud differentiation can be completed in late November.

When peony flowers bloom, they also have different characteristics. When the climate is normal, in February every year, the scale buds of peony flowers begin to grow, and the buds begin to appear when they are stung, and the spring equinox begins to pull out the flower stems.

The whole process is very long, and the main thing that affects its flowering is the temperature, which can prompt the peony to bloom earlier or later. From this characteristic, ensuring sufficient accumulated temperature can promote the flowering of peony flowers, and insufficient accumulated temperature can not bloom immediately, at this time, the temperature can be increased, which can accelerate the flowering of peony flowers.

Sowing stage: The first growth stage of peony flowers is the sowing stage, and at this time, the seeds with full grains should be selected for planting. Seedling stage:

and time seedlings, replenishment of seedlings, and apply thin liquid fertilizer every half month. Peak growth period: provide sufficient light time for peony flowers.

Flowering stage: increase the application of phosphorus and potassium fertilizers.

1. Sowing stage

Before planting peony flowers, you need to choose high-quality seeds that are round and plump and disease-free, and then soak them in warm water for six to eight hours to absorb enough water, and finally spread them evenly on the soil surface.

2. Seedling stage

When the peony flower buds, it will enter the seedling stage, at this time the plant has a higher demand for nutrients, so in the maintenance, it is necessary to apply a thin liquid fertilizer every half a month, so as to accelerate the growth rate of peony flowers, and at the same time to carry out seedling and seedling treatment, which is conducive to the vigorous growth of the plant.

3. Peak growth period

Peony flowers need sufficient light in the peak growth period, and they can be placed in a place with soft astigmatism, ventilation and coolness to promote photosynthesis of leaves, which is conducive to the synthesis of nutrients, but in summer, it is necessary to do a good job of shading measures to avoid the leaves of peony flowers being sunburned.

4. Flowering stage

When the peony flower enters the flowering period, it is necessary to apply nitrogen, phosphorus and potassium fertilizer-based fertilizer in time, and control the amount of nitrogen fertilizer, so as not to affect the differentiation and growth of flower buds, which is not conducive to the flowering of the plant and the huge flowers, and after the flowering period, prune the peony flower as soon as possible.
