How is flower and plant blooming period regulation done? A detailed method introduction

The ornamental value of flowers and plants is generally very high, and their flower colors are diverse and fascinating. However, the blooming periods of many flowers and plants are relatively short, so what methods can be used to extend the blooming period of flowers and plants so as to meet people's ornamental needs? Let us learn about it together.

I. Regulation of light

Light has a relatively strong inductive effect on any kind of flower or plant. Generally, short-day plants can be given 8-10 hours of light per day, with shading measures used for the rest of the time. Long-day treatment, however, is to add artificial light after the flower buds of the flower or plant appear, so that the continuous daily light period is about 14 hours, which can delay the blooming period. If it is a long-day plant that blooms in summer, its requirement for light duration is the opposite of that of short-day plants: extending light advances blooming; shortening light delays blooming.

II. Regulation of temperature

Some ornamental plants are not sensitive to light duration and can have their blooming period changed by increasing or lowering the temperature. Plants that have already formed flower buds in winter can, during the winter dormancy period and the low-temperature period in spring, be given appropriate warming treatment, which can shorten the dormancy time and bring the blooming period earlier. Before the temperature rises in spring, giving dormant plants a low temperature of 1-4°C can extend dormancy and delay blooming. For example, rhododendrons and wisteria can have their blooming period delayed by as long as 7 months. Plants such as cyclamen and geraniums enter dormancy or show poor growth in the hot summer; if the temperature is lowered below 26°C, their blooming period can be extended.

III. Controlling the growth period of flowers and plants

Controlling the sowing and planting period can also achieve the purpose of controlling the blooming period of flowers and plants. For example, gladiolus is sown in spring and blooms in summer, but if it is sown in early July, then it can be enjoyed in bloom during National Day.

IV. Regulation of nutrient distribution

Blooming period control of flowers and plants can also be achieved through techniques such as pruning and pinching, because pruning can reduce the consumption of nutrients in the plant body, concentrate nutrients in the flower buds, and advance blooming. Pinching can eliminate the apical dominance of flowers and plants, promote branching, and thereby delay blooming.

V. Application of plant growth regulators

The application of plant hormones and plant growth regulators is an effective method for controlling the growth and development of ornamental plants. At present, the commonly used agents are gibberellin, chlormequat, and others.

You can control and regulate the blooming period of flowers and plants according to the above methods, but note that different flowers and plants need to be given the corresponding methods to have a certain effect.
