Analysis on the Technical points of florescence Control of Common Flowers

How to regulate the florescence of common flowers and trees? Only by regulating the flowering period of flowers, will your late flowering period grow more and more exuberant. The following editor introduces the technical points of flowering regulation and control of flowers and trees and flowers.

1 controlling the initial stage of plant growth

Plants have a certain speed and time limit from growth to flowering. The flowering period of plants can be controlled by artificially controlling the breeding period, sprouting stage, upper pot stage and turning pot stage, and the arrangement can be made in advance according to the flowering season and time.

2 adjust plant growth rate with horticultural cultivation techniques

The plant growth rate was regulated by coring, pruning, bud picking, bud peeling, leaf picking, ring carving, grafting and other measures. The number of delayed days varies according to plant species, picking quantity and season; for flowers and trees blooming on the branches of the current year, early pruning in the growing season will lead to early growth and early flowering, and late pruning will lead to late flowering; stripping of lateral buds and lateral buds is beneficial to the flowering of main buds, removal of terminal buds and terminal buds, and is beneficial to lateral buds and lateral buds. Ring cutting makes nutrients accumulate in the upper flower branches, which is conducive to flowering; autumn ligation of branches can make leaves change color earlier; grafting scions with flower buds, such as Magnolia and Peach, can make them blossom ahead of time.

3 adjust the temperature

3.1 raise the temperature

Under the condition of low temperature in winter, increasing temperature can accelerate plant growth and blossom ahead of time. The heating date is inferred from the number of days required for plant growth and development to flowering, it should be heated gradually, and water should be sprayed on the plant every day during the initial heating, so as not to dry up the leaves. The night temperature is 15 ℃ and the daily temperature is 25-28 ℃.

3.2 reduce the temperature

Before the natural temperature warms up in spring, the artificial low temperature of 1-4 ℃ for dormant plants can prolong the dormancy period and delay flowering. This method can be used for all kinds of cold-resistant and shade-tolerant perennial root flowers, bulb root flowers and woody flowers. 2-year-old flowers and perennial flowers need a low temperature in their growth and development to bolt and blossom. For the flowers that have been pregnant and waiting for release, the flowering can be delayed by cold storage treatment, such as peony, eight immortal flowers, etc., which can be delayed for 1-2 months.

3.3 problems needing attention in temperature treatment

① has different temperature sensitivity among different varieties of the same kind of flowers. The temperature of ② treatment mostly depends on the climatic conditions of the origin or breeding place of the variety, and the temperature treatment generally takes > 20 ℃ as high temperature, 15: 20 ℃ as medium temperature and ≤ 10 ℃ as low temperature. The temperature of ③ treatment also varies with the climatic conditions of the cultivated land, the harvest time, the time from the market, the size of the bulb and so on. No matter in the growing period or in the dormant period, the suitable period of temperature treatment of ④ varies with the characteristics of flower species and varieties. The effect of ⑤ temperature treatment varies with the type of flowers and the number of treatment days. To control the florescence of many kinds of flowers in ⑥, temperature and light treatment should be carried out at the same time, or several treatment measures should be taken successively in order to achieve the desired effect. The cultivation management during or after ⑦ treatment also had a great influence on the control of flowering stage.

4 adjust the light

Light is an important environmental factor affecting the growth and development of flowers, and the formation and florescence of flower buds are closely related to the length of sunshine. This method is only used to deal with light-sensitive flowers.

4.1 short-day treatment

Short-day flowers, in the long-day season, as long as they grow strong, use artificial methods to make the whole plant light at 8: 10 hours a day, after a certain period of time can blossom. In addition, the shading treatment should be normal watering, fertilization, and pay attention to control the temperature, should not be too high, such as more than 30 ℃, some species will blossom irregularly, or even can not form buds.

4.2 long-day treatment

This measure is mostly used in the season of short sunshine in winter to make long sunshine flowers blossom. The method is to supplement the light with electric lights, but the temperature is low in winter, so we must cooperate to increase the temperature in order to be effective.

This is all we have said about the technical points for the regulation and control of the flowering period of flowers and trees and flowers, and we hope it will be helpful to the flower growers.
