How can we make chrysanthemums bloom in festivals?

Chrysanthemums usually bloom in late autumn. If its growing environment is artificially changed, it can bloom all year round. Especially during festivals, chrysanthemums are in full bloom, which is more suitable for market demand. The technical points of forcing flowers are as follows: 1. Flowers bloom on New Year's Day. There are two methods: first, continuous illumination in mid-August, or 16 18 hours of illumination every day to inhibit its flowering. On the eve of National Day, let it be exposed to natural light, so that it will germinate in the middle and late of 10 and bloom on New Year's Day.

Second, May Day blossoms. 12 In the second half of February, the aboveground stems of chrysanthemums were cut off, and potted chrysanthemums were transferred to the greenhouse at 15℃ and 25℃ to strengthen fertilizer and water management. Soon, many buds will grow on the old roots, leaving 12 healthy seedlings in each pot, which will sprout in mid-March and bloom in late April and May.

Flowers bloom on July 1st. In early February, the overground parts of last year's residual chrysanthemum were removed and placed in greenhouses at 15℃ and 25℃ for germination, and 12 seedlings were cultivated in each pot. From mid-March, shading treatment was carried out at 2 pm every day for 4050 days, and only 7 10 hour of light was given every day, so that flower buds appeared in late April and bloomed in early June.

Fourth, the National Day flowers bloom. In spring, it is divided into plants and propagated. It is shaded for 4050 days in the middle and late June, and buds appear in the middle and late August, and it blooms around the National Day.

Verb (abbreviation of verb) Note:

1. The old roots of chrysanthemum should be used to germinate seedlings, and nitrogen fertilizer should be properly applied to the previous chrysanthemum and the soil moisture should be controlled to facilitate the rapid germination of the old roots.

2. Pay attention to the light transmittance in the greenhouse. If the light intensity is insufficient when using a simple shed, it can be supplemented by electric lights. If ordinary bulbs are used for light supply, the height of the bulbs from the plants should be above 6070 cm to avoid scalding or affecting the growth and development of chrysanthemums. Simple darkroom or shading with black cloth must be sheltered from light and ventilated.

3. In the early stage of chrysanthemum growth, attention should be paid to cultivation and management to promote healthy growth. When plants grow to 30-50 cm high (depending on different varieties), they can enter the photophysiological development stage.

4. If the early growth is too fast and the plants are too high, it is not convenient to shade or move. You can use fertilization to promote water control, and you can also use coring in the early growth stage (multiple times) to promote short and strong plants.

5, shading treatment should be continuous and uninterrupted.

6. After the photoperiod of chrysanthemum, if it encounters high temperature weather above 27℃ and 28℃ or the average daily temperature is lower than 10℃ and 12℃, it will affect the flowering. It should be cooled in hot season and heated in winter.

7. The daily light of chrysanthemum should not be less than 6 hours, otherwise it will not bloom or delay flowering.

How to make flowers bloom in advance or later?

According to the principle that flowers can bloom only when they have reached a certain physiological state, people can artificially change or create some environmental conditions and take some special cultivation measures to make flowers bloom ahead of time or later according to people's wishes. The main technical measures to control flowering period include controlling light, changing temperature, applying growth regulator, controlling water and fertilizer, changing sowing date and pruning. , described below.

(1) controls the lighting. Different kinds of flowers need different sunshine for bud differentiation. According to the requirement of sunshine for flower bud differentiation, it can be divided into short-day flowers (such as chrysanthemum, poinsettia, Phyllanthus urinaria, Crab claw orchid, etc. ), long-day flowers (such as violets, cuiju, gladiolus, etc. ) and Chinese and Japanese flowers (roses, hibiscus, carnations, etc.). ). By artificially controlling the illumination time, measures such as shading and supplementing light are taken to shorten or extend the illumination time, so that flowers that need different illumination time can bloom in their non-flowering seasons.

For example, flowers with short sunshine should be shaded in the season with long sunshine time to make them have a long dark period, so as to meet the light demand in the process of flower differentiation and bud formation and promote their early flowering. Generally, short-day flowers are shaded from the end of July, and 9- 10 hours of light is given every day for about 45-65 days, and they can bloom around the National Day.

On the contrary, in the short-day season, the method of extending light can delay the flowering of short-day flowers and make long-day flowers bloom ahead of time. Such as gladiolus. In winter cultivation, the illumination time will be extended to more than 14 hours, and it can be opened in advance at a suitable temperature.

In recent years, scientific research has proved that flowers can bloom in advance if they are irradiated with high-intensity fluorescent lamps for about one and a half hours around midnight every day (the best effect is midnight) without general supplementary light. This method is also suitable for delaying the flowering of short-day flowers. Flowers with short sunshine can achieve their goal by giving less than half an hour of low toxic light in the middle of the night.

(2) Change the temperature. Most afternoon flowers are not sensitive to the length of light. As long as they can meet the temperature when flowering, they can bloom ahead of time.

In northern China, wintering plants, such as plum blossom, peach blossom, wintersweet and Spring Festival, which are moved into cold houses in late autumn, can be put into the room of 18℃- 24℃ about 20-25 days before the scheduled flowering, and given appropriate water and fertilizer, and then moved to 8℃- 15℃ after the flower buds swell and change color. Artificial cooling can also be used to inhibit the formation of flower buds and delay the flowering time. Before the temperature rises in early spring, the hibernating flowers in winter should be moved into a cold room while they are still dormant (the room temperature should be 1℃-3℃). Indoor with weak light, light for 3-4 hours every day, pay attention to proper spraying and watering, and keep the basin soil slightly wet. Generally, it can be stored for about 20 days before the flowering date, and then taken out to bloom as scheduled.

(3) Application of plant growth regulators. Plant growth regulators can promote and inhibit flowering. For example, camellia varieties suitable for flowering are pink and oriental bright. Another example is that many grass flowers are sprayed with 100ppM-200ppM of naphthylacetic acid, indolebutyric acid, etc. when the buds are not transparent. , all have obvious effect of early flowering. Another example is that 1-2 months before the flowering of Rhododendron cunense, spraying flower buds with 1000ppM solution can delay the flowering for about 10 days.

(4) Change the culture mode. Using drought treatment, sowing by stages and strengthening pruning to control flowering period is very effective for some flowers. For example, drought treatment can promote the early flowering of Solanum lyratum, clove and bauhinia.

Another example is many grass flowers, such as a bunch of red flowers, colored leaves, green chrysanthemums, impatiens and so on. By sowing in stages, flowers can bloom one after another in a long season. However, gladiolus is cultivated in stages, and with appropriate light and temperature, flowers can be enjoyed all year round.

For example, flowers and trees such as rose and jasmine that bloom many times a year, such as snapdragon, Petunia, carnation, Dutch chrysanthemum, safflower, etc., can bloom many times or extend the flowering time after flowering.
