How to breed daffodils?

Daffodils mainly have lateral buds, lateral bulbs, double-scale propagation and tissue culture.

The main results are as follows: (1) when castration bulbs are used for lateral bud propagation, the lateral buds wrapped inside are dug out and used as propagation materials. In autumn, the lateral buds are scattered evenly on the finished surface and covered with a thin layer of soil. The front of the front of Danzah should be watered thoroughly.

(2) Lateral bulb reproduction in autumn, the bulbs naturally divided on the mother ball were broken off to make seed bulbs for reproduction.

(3) there are many lateral buds in the mother ball of double-scale propagation of daffodils, basically there is one bud between two scales, and the bulb disk with one lateral bud can be cut into two scales as propagation material, which is called double-scale propagation. The specific method is that after the mother ball is treated at a low temperature of 4: 10 ℃ for 4 weeks, the bulb disk is cut at room temperature, each bulb disc contains 2 scales and 1 lateral bud, the upper end of the scale is removed, leaving 2cm as propagation material, and then put into a plastic bag containing 50% water vermiculite or 6% water sand. Close the mouth of the bag, put it in a dark place with a temperature of 20: 28 ℃, and grow small bulbs in 2 months. For planting.

How do daffodils breed daffodils

Daffodils like a warm and humid environment, flowering in winter and spring, good ornamental, many flower friends will put one or two pots in the bedroom. But I don't know much about it, so how do daffodils reproduce? What are the varieties of daffodils? Next, I would like to introduce the breeding methods of daffodils and the varieties of daffodils.

How do daffodils reproduce?

1. Lateral bulb reproduction

This is the most common and commonly used method of reproduction. The storage ball is planted on both sides of the bulb, and only the base is connected with the mother ball, so it is easy to break away from the mother ball. It will be separated from the mother ball in autumn and planted separately, and a new ball will be produced the following year.

2. Lateral bud propagation

Lateral buds are buds enclosed in bulbs. Only during bulb castration do they detach from the mother with the dug scales, pick out white buds, sow them on the seedbed in autumn, and produce new balls the following year.

3. Double scale propagation

A bulb contains many lateral buds, some visible and some invisible. But its basic rule is to spare two scales and one bud. Using a bulb disk with two scales as breeding material is called double-scale reproduction. The method is to put the bulb at a low temperature of 4-10 ℃ for 4-8 weeks, then cut the bulb disc small at room temperature, so that each piece has two scales, and remove the upper end of the scale to leave 2 cm as propagation material, then use a plastic bag to hold 50% water-containing vermiculite or 6% water-containing sand, put the breeding material in a bag, close the mouth of the bag, and place it in a dark place at 20-28 ℃ temperature. Bulbs can grow after 2-3 months, and the ball-forming rate is 80-90%. This is a new method that has been developed in recent years, which can be carried out in the four seasons, but it is better from April to September. The survival rate of the generated bulblets after transplanting is high, up to 80-100%.

4. Tissue culture

Using MS medium with 30 grams of sucrose and 5 grams of activated carbon per liter, bud tips as explants, or stem discs with double scales 5 × 10 mm as explants, PH 5-7 It was loaded into a glass tube of 20x100 mm, each tube of 10 ml culture medium, after disinfection, each tube was implanted with an explant, and then cultured in 25 ℃. After 10 days of inoculation, it produced small protuberances, and 20 days later, it was transferred into the medium containing NAA0.1/ mg 1 / 2MS. After 6-8 weeks, it had leaves and roots, and it was transplanted in the field with 100% survival. Using the stem tip as an explant, there is also the role of virus removal.

Varieties of daffodils

There are many kinds of daffodils, including Chinese daffodils, western daffodils, South American daffodils of the family Amaryllidaceae, colorful daffodils and grape daffodils of the hyacinth family (formerly classified as Liliaceae). There are many different varieties of each kind of daffodils.

3. The nickname of hyacinth of grape daffodil grape, also known as blue bottle flower, blue kettle flower, shoot vanilla, hyacinth family, blue kettle flower belongs to bulb plant, bulb is nearly spherical, covered with white skin film, leaves dark green, slender, raceme about 10 cm long, floret slightly drooping, flower is grape, the whole inflorescence is like a bunch of grapes, flowers are white, blue-purple, light blue and so on. The normal flowering period is from March to May. In the artificial cultivation environment, it can be advanced to January to February, or even earlier.

The leaves are green and fleshy. Pedicel extracted from the leaves, 15 cm to 40 cm long, raceme dense florets 10 to 30, bell-shaped flowers, Corolla curled back, another double variety, flowers are white, pink, yellow, purple, blue, red and so on, with strong or elegant aroma, natural florescence from March to April.

5. South American daffodils are also known as American daffodils and Amazon lilies. Amaryllidaceae and South American daffodils belong to perennial herbaceous flowers. The bulbs are enlarged like onions, ovate to widely ovoid, and covered with brown skin. Leaves narrow and long banded, dark green glossy, terminal umbels, scape hollow, flat tube-shaped, flowers are pure white, fragrant, flowering in winter and spring.

The above is for everyone to introduce the breeding methods of daffodils, as well as the varieties of daffodils, are we clear? Please pay attention to more household knowledge.

The efficacy and function of how to reproduce daffodils

Daffodils as white as snow, fragrant and fragrant, placed at home can not only beautify the home, but also have some other effects and functions. Next, I will introduce the breeding methods of daffodils, as well as the efficacy and function of daffodils.

The efficacy and function of daffodils

1. Beautify the home

Daffodils play a magical role. Slender leaves, dark green color, white petals and yellowed pollen, below is a different root, supporting the whole curved body, a rare plant appearance, so that daffodils appear quite prominent among plants, for beautifying the home, naturally have a very different role, look at other plants that look similar, and then look at the different-looking daffodils It doesn't have a taste.

2. Medicinal value

Amaryllidaceae Narcissus, belonging to the plant Narcissus, is used in medicine with bulbs. Collect in the spring and autumn, wash away the sediment, scald the boiling water, dry the slices or use them fresh. It tastes bitter, bitter and cold. There's a little poison. The main treatment is heat-clearing and detoxification, dispersing knots and detumescence. Used for mumps, carbuncle, furuncle, initial redness, swelling, heat and pain; daffodil root, the bulb of Amaryllidaceae daffodils. Efficacy of heat-clearing and detoxification, tamping or tamping juice can treat carbuncle, sore, insect bite, fish bone choking, but note that this product is toxic and should not be taken internally, if the bulb is eaten in large quantities, it will have mild toxicity. Some people confuse it with onions-people who eat daffodil bulbs have symptoms such as nausea, vomiting, abdominal pain and diarrhea.

3. Cleaning ability

We usually see that there are daffodils in the reservoir most of the time, and where there are daffodils, the water is generally relatively clear, and many of them can see the bottom of the pond, which proves that the decontamination ability of daffodils is very strong. Putting a handful of daffodils at home has the same decontamination effect on the air. If there is any place in the house that is particularly ventilated and the air is very muddy, you should consider putting one or two daffodils. At the same time, you should pay attention to it. The daffodils at home should be placed in a good position, and should not be placed in places where children can touch and cook water and dishes in the kitchen. If children are not careful, children may be poisoned if they mistakenly eat meals with daffodils pollen, reaching a certain quantity.
