Techniques for growing daffodils

daffodils

A. Characteristics of daffodils

Daffodils are herbaceous flowers of the family Lithospermum, and Chinese daffodils are one of the multi-flowered daffodil classes. It is one of the ten most famous flowers in China and is loved by people from all walks of life, experts and users at home and abroad. In order to enable users to better grasp the technology of cultivating daffodil flower bulbs, this article introduces the technique of raising daffodils in water.

B. Daffodil hydroponics

Daffodils are one of the ten most famous flowers in China, known as the “Lingbo Fairy”, and are the most ideal winter flowers to decorate New Year’s Day and Spring Festival. Its roots, stems, leaves and flowers have high ornamental value. Daffodils have a delicious color and fragrance, and are elegant and graceful. It was regarded as a “sacred flower” hundreds of years ago and has enjoyed a great reputation at home and abroad. They have been widely cultivated in China since ancient times, and are mostly found in the warm and humid areas of the southeast coast. Narcissus is a method to promote early flowering of daffodils.

C. Narcissus grown in water

Narcissus is a straight-arrow form, with green and green leaves, and its flowering branches are elegant and fragrant. The single-petaled flowers are in the shape of marigolds and silver plates, while the heavy petals are yellow and white with overlapping curls. They are popular and are the main flowers for home maintenance in winter.

D. Daffodils Selecting Good Seed Balls

If you want to cultivate a pot of daffodils with strong stems and leaves, many flowers, strong fragrance, and long flowering period, it is crucial to choose a good seed ball. When choosing a seed ball, select one that has the four characteristics of being large, solid, numerous, and thin. By large, I mean that the daffodil balls should be large and flat, especially the middle mother ball (the two sides are the daughter balls).

1. The larger the mother ball of daffodils

The larger the mother bulb, the more flower buds it contains, and the more flowers it will produce in the future.

2. The bottom of the mother bulb of daffodils

The base of the daffodil mother bulb should be wide and thick, and slightly sunken inward. If the edge of the bulb has a large number of small grains, it means that the bulb is highly mature and the root system is well developed around the edge of the bulb after being raised in water. It is good for growth and development, and the flowering period is also longer. 3. When you squeeze the daffodil ball in your hand, it feels hard and firm.

If the daffodil ball is hard and firm, and the daffodil head is flexible and columnar, it is a flower bud. This kind of daffodil ball has more nutrients, and the stems and leaves are thick and strong, and the flowers are more. On the contrary, there are more leaf buds and fewer flower buds.

4. More refers to the mother ball

There should be two bulbs on each side. According to the shape of the arrangement of the bulb, it can processed into upright, pencil, silver cup, rosette and crab claw type and other beautiful flower style.

5. Thin is the mother ball

The outer layer of slightly dried scale film should thin and tightly attached to the sphere. The dark brown, intact and bright ones are the best.

E.Daffodil Water Care Points

Dip the carved daffodil bulb wound side down in water for two days, remove it and wash off the mucus. Protect the bulb disk with cotton and maintain humidity so that the ball and root system are white and do not turn yellow due to sunlight.

1. Potting up water

As the saying goes, the art of daffodil modeling is three parts carving and seven parts nurturing. In addition to carving, it is also necessary to reprocess the artistic modeling in the process of hydroponics. Generally, it can be placed vertically or on its back in a pot with rocks so that the roots are facing down to absorb water, and the water cannot exceed the wound to prevent the bulb from rotting.

2. Initially

Put it in a cool place at 10-18℃ and wait for the new roots to grow out. Move to a sunny place for photosynthesis to make the leaves turn green.

3. In the process of aquaculture

To change water regularly, put water once a day. It is best to use rainwater or well water, tap water should precipitated for a day before use. This makes the roots grow well, the flowers are bright and the flowering period is long. If you drop red ink in the water, it will make the flowers turn red and achieve an unexpected and wonderful effect.

4. If the humidity is too low

Make it expected to bloom, use 20-25 ℃ warm water immersion or put in the sun at noon on a sunny day. To delay flowering, use cooling methods. To extend the flowering period, put a little salt or sugar in the water.

5. How to place daffodils

After sculpting, daffodil balls can placed on their backs, vertically, upside down, or overhead.

6.Placement of daffodils on their backs

The carved side of the daffodil is facing upward, with the roots facing sideways.

7. Vertical placement, i.e. square placement

The leaves and flowers are placed upward, and the roots are placed downward. Inverted is to keep the carved daffodil bulb upside down, i.e. with the leaves down.

8. Root facing up

Be sure to cover the bulb tray and roots with skim cotton and make the cotton sag in the pot.

9. Raise the roots by absorbing water

Place upside down i.e. inverted, with the wounded side facing down and the uninjured bulb one facing up.

F. Daily management

1. Light for Narcissus

At the beginning of the aquaculture period, place the pot indoors in the shade and avoid direct sunlight. After 4-5 days, when the leaves are greener, the wounds are healed and the roots grow out. Move the pot to a sunny and sheltered place and keep it indoors at night. After flowering, avoid prolonged sunlight to prolong the flowering period.

2. Water for daffodils

Water must changed every day for the first two weeks, once a day, and then every other day. Be careful not to hurt the roots when changing. To control the height of the plant, pour out the pot of water every night and add fresh water early the next morning. Water quality is the key to raising narcissus well. Narcissus should raised with well water, rainwater, river water or river water. If it is tap water, it is better to use the water after 2-3 days to prevent the danger of bleaching powder.

3. Air relative humidity

To 85%-95% is appropriate, the temperature is high when you can bite sprinkling water 1-2 times a day. If the room temperature exceeds 20℃ and the relative humidity is not enough, the buds will shrivel and dry up.

4. Daffodil temperature

The temperature should be 5-20℃, not too high or too low, of which 10-18℃ is the best. Too high a temperature will cause the leaves to grow, the flowers to be gray and the plants to dwarfed. However, it is also important to note that daffodils should not frozen, and if they are frozen, they cannot bloom.

5. Narcissus fertilization

As long as there is no lack of fresh water, it is not necessary to fertilize daffodils with water. If there is enough light, it will bloom without fertilizer. However, during the flowering period, add fast-acting phosphorus and potassium fertilizers. Therefore, you can add 1g of potassium phosphate and other fertilizers per pot when changing water. (If you have automatic irrigation equipment, you can use more efficient and fast water-soluble fertilizer)

G. Flowering control

Before cultivation, Narcissus bulbs can treated in a low temperature environment above 10℃ and below 4℃. And the heads are exposed to sunlight to inhibit the growth of nutrient organs and facilitate flowering.

① Suitable temperature and humidity

Conditions of hydroponics about 30d can bloom, the flower buds need 5d from rupture to flowering, when not open can be steamed with 40℃ hot steam.

②If the flowering period is too early

To delay the flowering time, you can when the buds have opened and the buds are expanding to open. Place the plant at a temperature of 2-3°C and keep the relative humidity of the air above 80%. Avoid direct sunlight, then the flowering branches stop growing and the well is in a semi-dormant state.

③Specific practices

Take a large piece of newspaper, spray it with water and wrap it loosely around Narcissus. Put them in the freezer for 7-10 days, then take them out and keep them in water for 1-2 days to bloom. However, you should be careful not to break the tender roots, otherwise it will affect the opening of the flowers.

④ can increase the temperature to promote flowering

That is, put 20 ℃ of warm water in the water tray, and keep sufficient light during the day. Continue to supply water at night, while hanging a 60-watt incandescent lamp at 50cm from the base of the plant to increase the light and temperature. So that the night can also be normal growth, so that the buds can open for several consecutive nights. At the same time, pay attention to spraying water to the foliage to prevent excessive drying of the leaves and injury to the bulbs.
