What are the influencing factors of peony flowering?

The flowering process of Paeonia lactiflora is affected by various factors, and the main influencing factors include four aspects.

(1) temperature:

In the same area, the morning and evening of peony flowering is closely related to the change of temperature in spring. Temperature can affect the whole flowering process. The difference in florescence between warm spring and cold spring can be 4-5 days or even 10-20 days.

(2) moisture and rainfall:

Water and rainfall have little effect on flowering, sufficient irrigation before flowering or rainfall will help peony blossom, large flowers, colorful flowers; but in case of heavy rainfall, flowers will be damaged, will fall ahead of time. If the soil water content before flowering is low, the flowers will become smaller, the flower color will not be bright, and the florescence will be shortened.

Temperature

Even in the same area, the temperature is different. Spring is the most exuberant season for peony flowering, and it is also a time when the temperature changes greatly. The temperature in warm spring and cold spring can be very different, so the flowering period will also differ by four to five days. When the temperature changes greatly, it is also possible that the florescence difference is about 20 days.

Moisture content

Water is also a major factor affecting the flowering of peony, peony likes to be wet, lack of water will delay flowering, but fear of waterlogging, too much water will also lead to non-flowering.

Rainfall

If it rains properly before flowering, the peony flowers will be very beautiful, the flowers are huge, and the colors will be very gorgeous. However, if there is too much rain, it will lead to the shortening of the flowering period of peony, the flower color is not bright or even does not blossom.

Altitude

The effect of altitude on the flowering of Paeonia lactiflora is mainly through the difference of temperature and humidity. At different elevations, the temperature and humidity of the air are different, so the florescence and the beauty of the flowers will be different.

Light

Almost all plants can't grow without light, and so can natural peony. Peony likes the sun and grows in sunny places, and the flowers are much brighter and more beautiful than those in the shade.

Planting season

Planted in spring, normally it will not blossom in that year, because the injured fleshy root cannot be recovered immediately; peony planted in autumn, the injured fleshy root has enough time to heal, it will usually blossom the following spring.

The main factors affecting the flowering of peony (1) temperature: in the same area, the morning and evening of peony flowering is closely related to the change of air temperature in spring. Temperature can affect the whole flowering process. The difference in florescence between warm spring and cold spring can be 4-5 days or even 10-20 days. (2) Water and rainfall: water and rainfall have little effect on flowering period. Sufficient irrigation or rainfall before flowering will help peony blossom, with large flowers and bright colors, but if there is heavy rainfall, the flowers will fall off ahead of time. If the soil water content before flowering is low, the flowers will become smaller, the flower color will not be bright, and the florescence will be shortened. (3) altitude deviation: altitude can affect the changes of air temperature, light and humidity, thus affecting the flowering period. In general, the florescence is delayed with the increase of altitude. For example, the flowering of peony in Luoyang ends on May 14, near Baiyun Mountain in Manxian County. The peony has just passed through the color. The flowering period of Paeonia lactiflora in Pengzhou City, Sichuan Province, is close to that of Danjingshan. Can make use of the different sea aid of the cultivation land to be highly exchanged, and the viewing period is long. (4) Light: light usually accompanies with temperature and has a significant effect on plant growth and development and florescence. The lack of light before flowering will affect the flower color, making it not strong enough, and the strong light during the flowering period, accompanied by a rise in temperature, will shorten the flowering period or burn the flowers. therefore。 Building a sunshade during the flowering period will prolong the flowering period of peony.
