The effect of temperature on the daffodil period! Hurry, Hurry, Hurry!!!!!!!!! 10

Let's give some information:

Daffodils belong to the Lycoris family, a perennial herb with bulbs.

If you want the fragrance of daffodils to fill the hall in the new year, first of all, you must understand the right temperature for the growth of daffodils. Scientific experiments have proved that room temperature 8-12°C is the most suitable for the growth of narcissus.

Secondly, daffodils need a certain amount of accumulated temperature from soaking to flowering. At a room temperature of 8-20°C, the higher the room temperature, the faster the flowering. Florist research confirms:

At room temperature 8-12 °C, it takes 40 days to flower; If the room temperature is kept at 15°C, it will bloom in 28-30 days; If the room temperature is 18-20°C, it will bloom in 23-25 days. The room temperature in the Pearl River Delta region is about 16-20°C from mid-January to mid-February, so it can bloom in 20-25 days under normal circumstances.

Third, the length of flowering varies with room temperature. So, how can you make the flowering period long and the aroma linger for a long time? Scientific control of greenhouses is the best way.

When room temperature = 23 °C, the flowering period is only about 7 days; At 8-12°C, the flowering period can be as long as 15 to 20 days; At 15-20°C, the flowering period has 10 days; If the room temperature is kept at about 4°C, the flowering period can last up to 1 month. According to the temperature conditions in the Pearl River Delta region, the flowering period can generally be maintained for 10 days.

Fourth, during the Spring Festival, family daffodils should be placed in a sunny and well-ventilated place away from heating and stoves. When the flower buds are about to bloom, they need to be moved to a cool place indoors, avoid direct sunlight, and keep the room temperature balanced and less variable.

Narcissus can also be raised indoors without heating, the only bad thing is that daffodils grow slowly and turn on slowly, about half to 1 month later than the general room temperature daffodils.

Maintenance method: Put the daffodil in a shallow basin (the general daffodil pot is fine), put in a part of the water, not too much, add water regularly, so that you can save the problem of changing the water. For the sake of daffodils, you can use some small stones to frame the daffodils and let it be placed as you wish.

If your narcissus is carved (i.e., peeled out of the buds), cover the wound (where it has been opened) with absorbent cotton and drizzle it regularly to keep the cotton wet. If the roots of the narcissus are very weak (in fact, they can do this if they are not weak), you can cover the roots with absorbent cotton and put a part of the absorbent cotton in the water. ps.

If you add too much water, or if you are looking at the narcissus in the shape of a bottle, you can change the water about once every 1-2 weeks.

I'm also anxious, big brother, big sister help.

The suitable temperature of daffodils is around 10 15, and it can be raised indoors without heating as long as the temperature can reach the standard. Generally, daffodils are normally aquacultured for 45 to 50 days and can bloom as scheduled.

The so-called normal water cultivation means to ensure that after the daffodil is raised, there should be 6 hours of light time every day, and the room temperature should be kept at about 10 15. If the weather is abnormal, the light is insufficient, and the temperature is too low (or too high), then it is necessary to take measures to ensure that the daffodils bloom as scheduled.

Daffodils do not have a specific suitable temperature, as long as they are placed in a sunny place, they can be raised without heating.

Narcissus is an autumn bulb greenhouse flower, which likes full sunlight, has tenacious vitality, can tolerate semi-shade, and is not cold-tolerant. From July to August, the leaves are dormant, and the flower buds are differentiated at the growth point of the bulb during the dormant period, which has the physiological characteristics of autumn and winter growth, early spring flowering, and summer dormancy.

Narcissus likes light, water and fertilizer, is suitable for warm, humid climatic conditions, and prefers fertile sandy soils. It prefers coolness in the early stage of growth, slightly hardy in the middle stage, and warm in the late stage. Therefore, it is required to have no severe cold in winter and no heat in summer, and rainy climate and environment in spring and autumn.

During the day, daffodil pots should be placed in a sunny place with plenty of light. Because plants need chlorophyll to provide nutrients through photosynthesis so that the leaves of daffodils are thick and straight, with bright green leaves and fragrant flowers.

As long as it's warm enough, it's fineCultivation method Narcissus likes sunlight and warmth, requires high air temperature, is not very cold-tolerant, and is afraid of heat, and needs moist and sandy soil without water accumulation during the vegetative growth period. Unlike other perennial herbaceous flowers, daffodils begin to grow in autumn, bloom in winter, store nutrients in spring, and dormant in summer.

There are two methods of cultivating daffodils: hydroponic and soil culture. Hydroponics is cultivated by shallow basin immersion. Put the germinated narcissus upright into a shallow pot of daffodils, and add water to submerge one-third of the bulbs.

The bulb can be fixed with quartz sand and pebbles in the pot. The daffodil pot should be placed in a sunny place during the day, moved indoors at night, and the water in the pot should be poured out to control the leaf growth. Add water again the next morning, taking care not to move the direction of the bulbs.

When it is first potted, the daffodils can be changed once a day, every 2-3 days thereafter, and once a week after the buds have formed. Narcissus grows well at 10-15 degrees Celsius and blooms in about 45 days. During the period of daffodils water rearing, it is especially necessary to give sufficient light, and it should be placed in a sunny place during the day and under the light at night.

This prevents the daffodil stems and leaves from growing, and makes the daffodil leaves short, broad, thick, strong, dark green in color, and fragrant in flowers. Water raises daffodils, generally do not need to fertilize, if possible, apply a little fast-acting phosphate fertilizer during flowering, the flowers can bloom better. Raising daffodils does not require any flower fertilizer, only water is used.

In order for the daffodils to grow strongly, they should be taken to the balcony to bask in the sun during the day. If you want to postpone the flowering period, you can use the method of lowering the water temperature, or you can pour out the pot water in the evening and add water in the early morning the next day. In addition, if you can't see the full buds 10 days before the festival, you can use the method of warming water to promote flowering, and the water temperature should be close to body temperature.

As long as you master the conditions for the conservation of narcissus, you can "bloom as you like"; Otherwise, it will be delayed, or even the leaves will not bloom. Soil cultivation is less commonly used in households, that is, the cultivation method of most soil-moistening flowers is used to cultivate narcissus. In mid to late October, plant large bulbs in small, perforated pots with fertile sandy soil, half of them exposed, and some fine sand should be placed under the scales in advance to facilitate drainage.

Place the pot indoors in plenty of sunlight and at a suitable temperature. 4 to 12 is good, the temperature is too low is easy to cause frost damage, too high temperature and insufficient light, it is easy to grow steeply, the plant is weak, the flowering time is short, and the ornamental value is reduced. If the requirements of light and temperature are met in management, the leaves are hypertrophied and the flowers are thick, so that the flowers can bloom large and the fragrance lasts.

Soil-grown daffodils can be topdressed two to three times before flowering. Daffodils cannot reproduce on their own due to limited climatic conditions. Cultivating daffodils, if there is no pest or disease damage, do not need to sprinkle pesticides.

In winter hydroponic daffodils, temperature, light, and water supply are the three factors that allow daffodils to bloom. Narcissus growth requires plenty of sunlight; The suitable temperature is 12 15; Clean water.

The suitable temperature for daffodils is 12 to 15 degrees Celsius. Likes the sun but should not be exposed!

Of course, it has to do with temperature.

The cultivation of daffodils is closely related to changes in temperature, so it is necessary to regulate the temperature to control the flowering period. If you need to bloom during the Spring Festival, you can generally start soaking in water about 26 days before the festival to promote flowering. Treat the daffodils so that they grow normally.

When the temperature is high, the daffodils grow fast, and there are signs of early flowering, it is necessary to provide proper shade to reduce the exposure of sunlight.

In case of dry low temperature and cold wave, it is estimated that it will not be able to bloom as scheduled, so it is necessary to keep warm from the cold, increase light, and take artificial warmth measures if necessary, such as using temperature regulators or raising flowers with warm water, etc., and can also use stool lights to supplement the light on rainy days.

Narcissus generally blooms in winter. Place on the table for extra moisture.
