Propagation methods and matters needing attention of daffodils

Daffodils usually need to be planted for several months before they can blossom, and some flower lovers will want to reproduce themselves after their daffodils bloom has passed. However, because daffodils are more famous ball flowers, so the method of reproduction is more special.

Daffodils (details)

I. 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.

Second, 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 place the bulb at a low temperature of 4 ℃ for 4 weeks for 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. Small 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%.

IV. 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 with a PH value of 5: 7; put into a glass tube of 20x100 mm, each tube of 10 ml medium, after disinfection, each tube was implanted into an explant, then cultured in 25 ℃, produced small protuberances after 10 days of inoculation, formed small balls after 20 days, and transferred to contain NAA0 after 1 month. In the medium of 1 / mg 1 / 2MS, there were leaves and roots after 6-8 weeks, and the survival rate was 100% after transplanting in the field. Using the stem tip as an explant, there is also the role of virus removal.

Culture methods and matters needing attention of daffodils

Daffodils are common green plants that beautify homes. Their leaves are dark green, and their white petals are particularly good-looking. They can beautify the environment and purify the air. But how should daffodils be raised? I will write out all the breeding methods and points for attention of daffodils and share them with you.

Culture methods of daffodils

1. Select the seed ball

Usually breeding daffodils is a kind of ball, selection is very important, when choosing a seed ball, you must choose a big, flat and hard seed ball, the middle of the film is very tight, and the skin color is bright, such a seed ball is easy to survive.

2. Growth environment

Usually raise daffodils, the growth environment is very important, daffodils is a kind of ornamental plants that like warm sunshine, and it likes the humidity of the air is relatively large, cold resistance is poor, and is afraid of heat, usually raise daffodils at home, it is best to put it on the balcony, it should be shaded in hot summer weather, and timely spray water to the leaves, moisture increases air humidity, winter The daffodils should be moved to a warm room.

Matters needing attention in breeding daffodils

1. Pay attention to diseases and insect pests in breeding daffodils

When breeding daffodils at ordinary times, we must pay attention to the occurrence of diseases and insect pests. Leaf blight, aspergillosis and penicilliosis are all high-incidence diseases of daffodils. After these diseases occur, they will directly affect the florescence of daffodils and, in serious cases, make daffodils die.

2. Attention should be paid to temperature control in breeding daffodils.

Most daffodils can blossom as scheduled after 45 to 50 days, but during the breeding period, we must pay attention to the temperature control, let it receive more than six hours of light every day, and in order to maintain between 10 and 15 degrees, lack of light or poor temperature control will affect the flowering time of daffodils.

Narcissus has been cultivated for more than a thousand years, and the fragrant daffodils have a very good ornamental value. Today we will take a look at the breeding methods and points for attention of daffodils.

Culture methods and matters needing attention of daffodils

I. cultivation of daffodils

Daffodils are suitable for cultivation in August and September. Make sure that the soil is ploughed loose before planting. Soft soil can help improve fertility and air permeability, and daffodils are more favorable for later cultivation. The permeability of the soil is better, and it can also be more conducive to the absorption of nutrients and nutrients.

Second, the culture method of daffodils-- fertilization.

Daffodils need organic fertilizer, and it is more appropriate to use some calcium phosphate as fertilizer. The amount of fertilizer used for annual daffodils can be reduced to 10 kg per mu. Fertilize evenly so that the soil can absorb nutrients evenly. Keep the bottom of the ditch smooth per mu so that the water can flow smoothly.

Third, the culture method of daffodils-irrigation

Daffodils need to keep a current in the canal, the size of which is related to the growth stage and season. There is more water in the north and less water in the southwest. The amount of water can be increased in cold weather and reduced in warm weather. The amount of water should be changed on rainy days or sunny days.

Fourth, the culture method of daffodils-- topdressing

Daffodils like fertilizers and can use some fertilizers as soon as they sprout. After that, you can apply fertilizer every seven days or so in the process of growing.
