Influence of Spring Temperature on Flowers

China has a vast territory, complex terrain, and different climates. beginning of spring is inconsistent with the length of seasons. Therefore, flower cultivation should be based on the actual temperature as the basis of flower management.

The average temperature in spring should be between 10~22℃. Although the rainy season has come in early spring, the temperature is still below 10℃, and it is still winter. Before the long summer, the average temperature reached above 22℃, and the summer arrived earlier, so it was not the temperature in spring.

The arrival of spring begins gradually from south to north. The solar terms in beginning of spring are on February 4th and 5th every year. At this time, the temperature is melting, the streams are tinkling, and the temperature is obviously higher than that in winter.

The outdoor temperature in early spring often makes people feel colder than in winter.

There are two reasons for this:

One is that there are often cold waves in early spring, which affect the sudden change of the earth's temperature. Because before the cold wave comes, the temperature is often very high, and after it comes, the temperature drops a lot, and people and plants can't adapt to the changes in the temperature environment.

Secondly, there are more clouds and rains in spring, which hinders the radiation of the sun and consumes the heat in the ground and air. These are all external factors.

The low temperature in early spring is also caused by internal factors: in winter, people move flowers indoors or in greenhouses. Although the cold wind blows outside and the frozen snow drifts away, even so, as long as there is proper moisture, temperature and sunshine, the flowers that enter the room will still be lush and grow well.

When early spring comes, people can't wait to move the flowers out of the house to bask in the sun. When the spring breeze blows slightly, people will feel gentle and relaxed, but in the human body, there is a cold feeling. This feeling of contradiction with the outside temperature is caused by the physiological changes of organisms.

When winter goes and spring comes, the surface of organisms is stimulated by cold winter, and the sealing degree of hair pores is correspondingly reduced; In addition, the body is dominated by the biological clock. After spring, the surface of organisms is in an active stage, and the stomata of plants are released from hibernation and open.

Therefore, the spring breeze blows, although it is not very cold, but it can drive directly into the living body, and it has a cold feeling. In addition, improper defense in spring and cold, changeable climate, hard to prevent, once the outdoor flowers catch cold, it will cause irreparable harm. It is often said that winter goes and spring comes green, which is the reason.
