(1) It takes about 2 to 4 days to see the flowers that germinate for 20 days (more in line with the winter vacation time).

(2) Water while planting, and always keep it moist without any fertilizer, so it grows better and better. Using meteorological conditions to raise daffodils.

Narcissus belongs to Amaryllidaceae, a perennial herb with bulbs.

If you want the fragrance of daffodils to overflow the hall during the Spring Festival, you must first know the suitable temperature for daffodils to grow. Scientific experiments have proved that the room temperature of 8- 12℃ is the most suitable for narcissus growth.

Secondly, narcissus needs a certain accumulated temperature from soaking to flowering. When the room temperature is 8-20℃, the higher the room temperature, the faster the flowering. The florist's research confirmed that it takes 40 days to blossom at room temperature of 8- 12℃; If the room temperature is kept at 15℃, it will bloom in 28-30 days; At room temperature 18-20℃, it will bloom in 23-25 days. 65438 Pearl River Delta region1The room temperature from mid-October to mid-February is about 16-20℃, and flowers can bloom in 20-25 days under normal circumstances.

Thirdly, the length of flowering period changes with the change of room temperature. So, how can we make the flowering period long and the fragrance stay long? Scientific control of greenhouse is the best way. When room temperature >: when = 23℃, the flowering period is only about 7 days; 8- 12 C, the flowering period can be as long as 15 to 20 days; When 15-20℃, the flowering period is 10 days; If the room temperature is kept at about 4℃, the flowering period can be as long as 1 month. According to the temperature conditions in the Pearl River Delta, the flowering period is generally sustainable 10 days.

Fourth, during the Spring Festival, family members should put daffodils in sunny and well-ventilated places, away from heating and stoves. When the buds are to be released, they need to be moved to a cool place indoors to avoid direct sunlight and keep the room temperature balanced.

(3) The water is a little turbid and seems unclean.

(4) keep a diary at any time according to the winter vacation time:

Today, I planted a narcissus. I first found a piece of foam, cut a hole the same size as the daffodil in the middle, then put the daffodil through the hole, then put the daffodil into a bottle filled with water cut in half and started planting.

(The best interval is 1 week): I found that daffodils have taken root and look like carp beards, slender and slender.

(Every four or five days): I play at my grandma's house during the day and come home at night to find that it has sprouted. Buds are like turtles that have just hatched. Green is so interesting!

(Every two or three days): When I come home from school today, the first thing to do is to see daffodils. I ran to have a look and found that nothing had changed. It was still the little bud. How I wish it would grow up quickly!

(ten days apart): I went home for dinner at noon, and I went to see the daffodils anxiously. Wow, I found Xiaolei has grown up! Sharp as a needle and long as a bamboo leaf, I am extremely happy!

(a week apart): I went to see it today and found that the tender leaves had grown a small flower. It looks like a child who doesn't want to put on new clothes. So cute!

(One week apart): Today, I came to see Baby Flower, and found that it has white petals, which looks like snowflakes flying in the winter sky. I was shocked!
