Generally, germination can be seen in 2-4 days. 5-12 o'clock, 40 days before flowering; If the temperature is kept at room temperature for 15 days, it will bloom for 28-30 days; If the room temperature is 18-20, it will bloom in 23-25 days. The room temperature in the Pearl River Delta region is about 16-20 from mid-January to mid-February, so it can bloom in 20-25 days under normal circumstances.

Adult plants are 20-30 cm tall. Normal flowering takes about 25 days, high temperature will be slightly early, low temperature will pull back flowering, flowering period is generally 10-15 days. In order to make the flowers strong, they should be exposed to the sun during the day, and in order to avoid frostbite of the flowers, please do not place the flowers in a place where the temperature is too low.

The water temperature controls the flowering period.

The leaves grow slowly at first, but later they begin to grow quickly, and the buds will be pulled out in about 1 and a half months, and they will bloom after 10 to 15 days, when the leaves are barely long.

There are four main stages in the growth process of daffodils. The first stage: the daffodil bulbs begin to grow roots, about five centimeters; The second stage:

Daffodils will grow many new shoots; Stage 3: White flowers will bloom on the top of the daffodil; Stage 4: The daffodils are in full bloom and emit a faint fragrance.

There are many characteristics of daffodils, but there are three main ones that are the most common. The first point: the color of its flowers is very elegant, fresh white; The second point:

When it comes to maintaining daffodils, they only need water to bloom; The third point: it does not need fertilizer when it is maintained, and it can grow well.

Narcissus is an autumn bulb greenhouse flower. It loves sunlight and has a strong vitality. It can tolerate half shade and half cold. From July to August, the deciduous leaves are dormant.

Flower bud differentiation is carried out at the bulb growth point in the dormant stage, which has the physiological characteristics of autumn and winter growth, early spring flowering, and summer dormancy. Narcissus loves light, water, and fertilizer.

Suitable for warm and humid climatic conditions and fertile sandy soils. The early growth stage is cool, the middle growth stage is slightly coldy, and the later growth stage is warm. Therefore, it is required that there is no severe cold in winter, no scorching heat in summer, and rain in spring and autumn.

Seed propagation: (1st year) Seed germination - long leaves - breeding bulbs - dormant (2nd year) bulb germination - long leaves - breeding bulbs - dormant (3rd year is basically the same as 2nd year) (4th year) mature bulbs germination - long leaves - flowering - breeding bulbs - dormancy.

Dividing propagation: the same process as the second and third years of the first type, and then flowering, that is, the flowering period is 1-2 years earlier.

The leaves of narcissus are drawn from the greenish-white cylindrical sheath at the top of the bulb, and then the flower stems are extracted from the leaves, generally each bulb can draw 1-2 flower stems, and more can reach 8-11 branches, umbel-shaped inflorescences. Most of the petals are 6 petals, and the end of the petals is goose-yellow. The bulb is ovate to broadly ovate-spherical, covered with a tan epithelium.

The leaves are narrow and long-banded, the capsule chamber is dehisced on the back, and the flowering period is spring.

The first seed propagation: (first year) seed germination - long leaves - fertile bulb - dormant (second year) bulb germination - long leaves - fertile bulb - dormant (third year is basically the same as the second year) (fourth year) mature bulb germination - long leaves - flowering - fertile bulb - dormant.

The second type of rametre propagation: the same process as the first type in the second and third years, and then flowering, that is, the flowering period is 1-2 years earlier.

The third type of tissue culture: Chinese daffodils are generally not used because of their high reproduction rate, and are mostly used in the mass production of daffodils, which can produce seedlings with similar seedling specifications in a short time.

Germination, budding, flowering, withering, seeding, death.

There are four main stages in the growth process of daffodils, the first stage is that the daffodil bulbs begin to grow roots, and the root system can generally grow to about five centimeters, and then the second stage, the daffodils at this stage will grow many new shoots, and then the third stage, when the top of the daffodils will bloom white flowers in front of the hand, and finally the fourth stage, the flowers of the daffodils begin to bloom and exude bursts of fragrance.

Daffodil is one of the traditional Chinese flowers, the fragrance of daffodils is relatively special, the flowers of daffodils are yellow-white and grow very beautiful, so many people will choose to plant a pot of daffodils for ornamentation, the growth cycle of daffodils is generally about 9 months, usually daffodils are cultivated in autumn from September to October, the leaves will wither and yellow around May of the second year, and enter the dormant period in the form of bulb balls in June or so.

Daffodils growth process.

There are four main stages in the growth process of daffodils, the first stage is that the daffodil bulbs begin to grow and destroy the root system, and the root system can generally grow to about five centimeters, and then the second stage, the daffodils will grow many new shoots, and then the third stage, when the top of the daffodils will bloom white flowers, and finally the fourth stage, the flowers of the daffodils begin to bloom and exude bursts of fragrance.

How to grow daffodils.

1. Illumination:

Daffodil is a short-day plant, very fond of sunny places, spring and autumn should ensure a minimum of 6 hours of light per day, winter to the whole day of sunlight, summer when the sun is the strongest, daffodils should be placed in a place where the light is scattered, but daffodils should not be exposed.

2. Moisture:

Daffodils are different from most plants, mainly growing in autumn and winter, autumn and spring temperatures are about the same, only need to be watered every three days to maintain soil moisture, winter temperatures are low, need to be watered every five days, summer needs to be watered once every two days, only sufficient water can make daffodils grow more vigorous.

The growth process of the daffodil: at first the yellow bud dots on the bulb turn green, then six long leaves grow, and a green flower grows in the middle of the leaf, and finally the flower blooms and exudes a burst of fragrance.

Daffodils in the budding period are suitable for planting in warm, moist soil, which is convenient for seeds to germinate and take root, and the roots, stems and leaves of daffodils in the growth period belong to the differentiated state, and the appropriate amount of fertilization can supplement their nutrients, the flowering and pollination period is a sign of daffodil maturity, and the fruiting reproduction period is a good time for daffodil seeds to be harvested.

Daffodils are autumn bulbs like warm core chamber flowers, like full sunshine, tenacious vitality, can tolerate semi-shade, not cold-tolerant, daffodils usually fall leaves in July and August to dormant, in the dormant period of the bulb growth point part of the flower bud differentiation, with autumn and winter growth, early spring flowering, summer dormancy physiological characteristics of Hui's.

Narcissus likes light, water, fertilizer, suitable for warm, humid climatic conditions, likes fertile sandy soil, its growth in the early stage of cool, the middle of the slightly cold-tolerant, the later period of warm, so in the winter no cold summer no heat, spring and autumn rainy climate area planting is appropriate.

Distribution:

Native to the warm coastal areas of eastern Asia, Zhejiang, Yunbi digging Fujian coastal islands are self-growing, but all the people seen in various provinces and regions are cultivated for ornamentation.
