How to apply flower fertilizer to peony flowers in spring? How to cultivate? How often do you water it?

Chemical fertilizer is often applied in spring and summer, and it is combined with watering before and after flowering. Potting can be combined with watering and applying liquid fertilizer. After planting for one year, it is feasible to fertilize in autumn, mainly with decomposed organic fertilizer. It can be combined with loosening soil, smearing and acupoint application.

Water it once after planting. Peony should not accumulate water, so it should be watered as appropriate during the growing period. In the arid areas of northern China, water before flowering, water after flowering and frozen water are generally used for irrigation. For the convenience of management, potted plants can be cut off and buried underground after flowering.

Cultivation techniques of peony flowers;

First, planting

The soil should be loose, fertile, neutral and slightly alkaline. Cut off the roots and diseased roots of the planted peony seedlings and put them in a pot or pit prepared in advance. The root system should be stretched, and most parts of the basin or pit should be gently lifted and shaken when filling, and the soil should be sealed tightly, and the root system should be slightly lower than the basin surface or ground level.

Second, intertillage

During the growing season, timely intertillage, uproot weeds and pay attention to pests and diseases. In autumn and winter, the peony plots for more than two years should be ploughed.

Third, pruning

In the year of planting, multiple rows of stubble should be leveled. After germination in spring, leave about 5 branches, wipe off the rest, concentrate nutrition, and make the flowers in the next year big and bright. Combine autumn and winter to clear the garden, cut the stems, and be thin without flowers. When carrying a flowerpot, trim it into your favorite shape as needed.

Fourth, spray drugs.

Spraying sulfur mixed solution before germination in early spring, and using mixed solution of pesticides and fungicides in summer, once every two weeks as appropriate. Combined with fertilization, chemical fertilizers and growth regulators should be added.

Five, change the basin

When potted peony grows to three or four years, it needs to be replaced with a big pot with new fertile soil or planted alone in autumn.

Sixth, urging flowers

In order to increase festivals or celebrations, peony can be heated about 50 days in advance according to the variety, and the temperature should be controlled at room temperature 10-25℃ and the average daily temperature 15℃ ... Pay attention to keeping the plants moist in the early stage, pay attention to ventilation and light transmission after budding, and control the temperature according to the requirements of flowering period after budding. Foliar fertilization should be done at ordinary times to ensure adequate water supply. So you can see flowers at any time in winter and spring.

Seven, watch

The natural flowering period of a single tree peony is about 10- 15 days, which is shortened with the increase of temperature and can last above 3-8℃. Temporary scaffolding can be used to block the wind and light, extending the viewing time; When lifting the basin, move it to a place out of direct sunlight, with a temperature of 5 5-10c and a transparent environment.

According to the appearance and humidity of the pot soil, water the flowers in time to make the flowering period the longest; When flowers need to be cut, the wound should be cut or scalded with water. Preservatives or a little sugar should be added to the water of flower arrangement to prolong the flowering time of flower arrangement.

Kelp is rectangular with dense yellow-brown bristles. Flowering in May; The fruiting period is June.

Flowers are colorful, jade smiles and pearls are fragrant, romantic and elegant, and they are known as "the king of flowers". In terms of cultivation types, it can be divided into hundreds of varieties mainly according to the color of flowers. "Peony has many varieties and colors, with yellow, green, fleshy red, crimson and silvery red as the top grades, especially yellow and green. Peony flower is big and fragrant, so it is also called "national color and fragrance".

Peony flowers can be eaten. Eight Notes on Respect for Life in the Ming Dynasty states that peony petals can also be fried, which is the same as Er Ru Pavilion and Room Manual in the Ming Dynasty. It says, "Peony flowers can be fried, just like magnolia flowers, edible and soaked in honey" and "petals can be washed and wiped, and fried with fragrant oil to the end". Many places in China use peony petals to make peony soup, or add color to side dishes to make famous dishes. Peony petals can also be steamed into wine, and peony dew wine made of peony petals has a mellow taste.

Peony flowers can also be used as medicine, and the varieties of medicinal cultivators are monotonous, and the flowers are mostly white. Taking root bark as medicine is called Cortex Moutan, also known as Cortex Moutan, Powder Cortex Moutan, Scraping Cortex Moutan, etc. , is a commonly used Chinese medicine for cooling blood and removing blood stasis. Li Shizhen said: "Peony is called peony, although it is seeded on the roots to raise seedlings." He also believes that it is better to use wild single petals as medicine, and the artificial double petals cultivated for ornamental purposes are not pure and cannot be used as medicine.
