Medicinal value
The narcissus is used in the medicine, collected in spring and autumn, washed off the sediment, and after boiling water, the slices were dried or used, and there were small poison.It has the effects of clearing heat and detoxifying, dispersing swelling and swelling.It is used for mumps, poisonous poisonous redness, swelling and heat pain at the beginning.
Chemical ingredients: contain a variety of alkaloids such as pseudohydrine, stone garlic alkali, multi -flower pylonder, and Zhangzhou aquacon pheasant.Daffodils have certain anti -cancer and antiviral activity.Also belonging to plant white water fairy bulb contains white aquatic amine, stone garlic, polymerine, cedarine, and pseudohydrine.
The toxic plants include the Chinese plant map database. It is toxic and toxicity of the whole grass, and the bulb is highly toxic.After eating, there are vomiting, abdominal pain, frequent pulse, cold sweat, diarrhea, irregular breathing, rising body temperature, lethargic, collapse, etc. In severe cases, spasm, paralysis and death.The leaching agent of the bulb has a strong excitement for the uterus of guinea pigs, rabbits and cats, which can vomit pigeons.Mouse abdominal injection of narcissus total alkaloid LD50 is 182mg/kg; Dog muscle injection is 16mg/kg, and activities are reduced, not eaten, and partially die.
Economic value
The flowers of daffodils are gloomy, and the oil content of flowers is 0.20%-0.45%. After refining, it can be adjusted with fragrance and spices; it can be prepared perfume, soap and senior cosmetics.Narcissus fragrance is an indispensable raw material in the fragrant style.The narcissus flowers are fragrant and overwhelmed. It uses narcissus flowers and tea to make high -grade daffodils tea, narcissus oolong tea, etc. The tea is fragrant and sweet.
Breeding method
illumination
Narcissus flower is a short -day plant -rooted plant, as long as 10 hours of light every day.In the growth stage, I like multi -light, and sufficient light is conducive to the assimilation of plants to accumulate nutrients.During the autumn and winter, it is generally sunny, and the day is short and long, and the narcissus can successfully pass the light stage.During the autumn and winter of Fujian, there are many sunny days, short day and night, cool temperature, and the most suitable for growth.
Humidity/watering
There are more water in daffodils than ordinary plants.There is not much water in the early stages of the bulb, as long as the soil is moist.During the period of growth and development, the rapid development of various organs is fully developed, and the amount of water and Fertilizers must be supplemented in time.The maturity period is weakened, and the need for water has also decreased accordingly to completely stop.
The daffodils are damp types. Different requirements for moisture at different stages of development. The water consumption requires a small amount of water in the early stages of bulb planting. As long as the soil is wet.In the period of strong growth and development, the amount of water requires a large amount of water. It must be replenished in time and often irrigated.The metabolism activities of the mature period have weakened again, and the requirements for moisture have been reduced accordingly.
temperature
In the early stages of growth, daffodils like coolness, warm in the later period, and cold to resistance in the middle but not to have severe temperature differences.According to the place of production, when the temperature is 17-23 C and the humidity is 70-80 %, the most suitable bulbs grow and swell.
soil
The daffodils are very adaptable to the soil. They can grow except for heavy sticky soil and gravel ground.The amount of soil and other soils rich in organic matter and well drainage can be planted.
Avadascular flowers like sandy loam with loose texture, good structure, and strong water retention.Lightweight soil, accumulation soil, and other organic and well -drained soils are also available.Chongming Island, Jiangsu and the daffodil area in Zhangzhou, Fujian, is located in the lower reaches of the Yangtze River and the Fujian Lajiang River Basin.And cultivation.
Fertilize
The nutrients in the scales of narcissism after the gestation buds are almost exhausted, so fertilization should be appropriately applied in the later stages of growth.Starting from pregnancy, when changing water, a small amount of potassium dihydrogen phosphate (0.5 grams each time) is applied to the pot or a 0.2 % potassium dihydrogen phosphate is used to spray the leaf surface.Add 1/4 of aspirin with 0.3 mg of aspirin or one tablet containing 0.3 mg of aspirin.
Family hydrostatic
1. Choose the ball
The advantages and disadvantages of Narcissus balls determine how much flowers bloom and whether the floral fragrance is rich.If you want to raise a good pot of narcissus flowers, you must start with the choice of aquarium.
2. Cultivation method
Cultivation of narcissus has two methods: hydroponic method and soil training method.
The hydroponic method is cultivated by shallow pot water soaking.It is advisable to put the daffodils that are treated upright in a daffodils, and it is advisable to add water to one -third of the jeruscus.Blinds can be fixed with quartz sand and pebbles in the pot.
During the daytime, the water fairy pot should be placed in a sunny place, moved into the room at night, and pour the water in the basin to control the leaves.Add water the next morning, be careful not to move the direction of the bulb.When the pot is just the pot, the narcissus can be changed once a day, and then changes every 2-3 days. After the buds are formed, change the water once a week.Narcissus grows well in an environment of 10-15 C, which can bloom in about 45 days, and the flowering period can be maintained for more than a month.
During the water fairy water, sufficient light must be given, and it must be placed in the sun during the day, and it can be placed under the light at night.This prevents the narcissus stems of the stems and leaves.Aquatic narcissus generally does not need to be fertilized. If possible, apply some fast -acting phosphorus Fertilizers during the flowering period, and the flowers can be bloomed better.
Forever you need any flower Fertilizer, only water can be used.In order to make the narcissus grow strong, the balcony should be taken during the day.If you want to delay the flowering period, you can take a method of lowering the water temperature, or take the pot water in the evening, and the next morning, add water.In addition, if you do not see a full bud in the first 10 days before the section, you can use the method of warm the water to urge the flowers. The water temperature should be close to the body temperature.
Families of soil cultivation are rarely used, that is, the cultivation method of most moisturizing flowers to cultivate daffodils.In mid -and late October, large lumps of bulbs were planted into small pores with a fertile sandy soil, and half of them were placed in half. Under the scale, some fine sand should be padded in advance to facilitate drainage.Place the Flower pot in the room with sufficient sunlight and suitable temperature.It is good for 4-12 C. The temperature is too low to cause frost damage. If the temperature is too high, and the light is insufficient, it is easy to grow steep, the plant is weak, the flowering time is short, and the viewing value is reduced.If you meet the requirements of light and temperature in management, the leaves are hypertrophy and the flowers are thick, so the flowers can be blooming and the aroma is lasting.Tupei narcissus can be applied two to three liquid Fertilizers before flowering.
3. Control the flowering period
The flowering period of narcissus is earlier than peaches and plums.Generally, it starts to raise water in autumn and winter, and it can bloom in winter and spring.This goal can be achieved through artificial control.
Generally, Narcissus balls can be bloomed as scheduled for 45-50 days.The so-called normal water care, that is, to ensure that after the water fairy water is kept, it should have 6 hours of light every day, and it is advisable to keep the room temperature of about 10-15 C.In case of abnormal weather, insufficient light, and too low temperature (or too high), we must take measures so that narcissus can bloom as scheduled.
When the temperature is too low and the light is insufficient, you can replace the warm water of 12-15 C in the narcissus basin; at night, use a plastic film to surround the narcissus basin, and use the 60-watt light to spend 40-50 cm.At the same time, spray water on daffodils to prevent the temperature from rising suddenly.
When the temperature is too high, add cold water to the daffodil basin, and pour water in the basin at night to perform low temperature treatment, which can delay the flowering of narcissus.
4. Prevent long -term
The key to want to cultivate a narcissus flower with short leaves and long flower stalks is to promote the growth of flower stems and avoid the length of the leaves.When nourishing narcissus flowers, remove the brown envelope film on the outside of the narcissus ball, cut a knife vertically between the sprouts of the upper part of the narcissus ball, cut 3-4 layers of scales, and cut one knife on each side. Do not hurt.And flower bud, wash off the mucus, and cultivate in a shallow basin.
Put it in a sunny place during the day, pour water in the pot at night, and add water to cultivate in the morning, so as to avoid the length of the leaves.
You can also plant or potted plants first to achieve the effect of short flower stems in the leaf.The specific method is to first plant the daffodil ball into a place with sufficient sunlight, water it every day until the flower stems are pulled out, then the narcissus ball is dug out, the soil is washed away, and the water is watched indoors.
5. After flowering
Generally speaking, after the spring Festival, the narcissus flower fades.It is usually a pity that people throw away the flowering daffodils.Narcissus is a perennial plant that breeds by bulbs. If the bulbs that have been blooming have been bloomed into the soil, it can continue to grow and reproduce.
Choose the backwind to the sun or the deep vegetable garden or the nursery land. After the rake is tied, it is built into a high ridge.After a month, the blades withered and dormant. At this time, the bulbs are dug, cut off the roots, and cut off the yellow leaves along the base, and then buried the bulbs. The depth should be 10 cm.Pole urine, then rake flattened.Can't save trouble, and buried it into the Flower pot, because the bulbs have to spend long spring, summer, and autumn seasons in the soil, especially in summer and autumn.Leaves without leaves, if you forget to fertilize them, will cause drought death.
6. Prevent dumb flowers
The so -called "dumb flower" refers to the phenomenon of daffodils that the flowers died in the middle of the water.The phenomenon of "dumb flowers" is mainly caused by the following reasons:
The quality of Narcissus ball is poor.The sphere is small, and the flower buds are dysplasia; the sphere is suffering from pests and insect pests.
Improper maintenance.If the water is not diligent, the light is insufficient, the room temperature is too high, and the ventilation is poor, causing the leaves to be long and thin.In addition, when you change the water, you will also cause "dumb flowers".
Improper water care seasons.If the bulb before frost is in dormant period or when the temperature rises after the clearing, "dumb flowers" will appear.
To prevent "dumb flowers", we must first choose high -quality bulbs for three years for water care.It is best to use rainwater or pond water for water. If you use tap water, it should be stored for one day.Then it is to ensure that the daffodils raised are not less than 6 hours a day, and indoor ventilation should be paid to indoor ventilation.The temperature is maintained at 12-15 C, the most conducive to the growth of narcissus.In the north, the weather is dry and spray water at narcissus plants every day.
7, dormant germination
Dipping out: Peel off a layer of brown Skin on the outside of the bulb ball.
Cut the ball: 1/3 of the left and right of the upper half of the bulb ball, cut the horizontal horizontally, and then cut the scales 2-3 layers of scales.To the half waist of the ball.*Avoid bidding buds during operation, and carefully remove old roots and soil at the bottom.
Soaking the ball: Soak the cut bulb ball with water for 1-2 days, and then rinse the rubber flowing out of the ball.
Get bud: The soaked bulb ball needs to be exposed in the sun. It is best to put it in a container and cover a layer of bran.Watering once a day so that the bran is kept temperature and humidity.At this time, pay attention to cold and light, and can be covered appropriately.One week later, the new buds can be exposed to fully illuminate the sun.About 50 days, the flower head is out, and the water fairy ball can be removed and rinsed out.
8. Related skills
Aspirin can help the water fairy flowers in full bloom: Use 1-2 pieces of Aspirin pills to dissolve in the water to replace the water in the narcissus Flower pot, which can make the flowers stronger and lush.
Daffodil temperature increases flowers: Daffodil grows slowly at low temperature, and can use the method of warming to urge flowers.
sunlight heating: Under the daytime sunlight, or in front of the glass window in the south of the south, it is until it flowers.
Temperature heating: Cover the plastic cover in the Flower pot, turn on the electric light, and stop the temperature in the cover to 23 C.
increase the electric heater: Open the electric heating device or place the hair dryer in the place where the water fairy flowers will not be burned, so that the warm wind will slowly blow the flower body, and the flowers will bloom for several consecutive days.
Temperature heating in warm water: Put a small amount of warm water in the water basin to raise the water temperature to 12-15 C.
Salt extension of the narcissus flowering period: When the narcissus flowers are in full bloom, put a small amount of salt into the pot, which can extend the flowering period.Do not put salt when the narcissus is put in the bud, otherwise it will suppress the opening of the flower bud.Or use two pieces of aspirin into powder and put it in 1000 ml of water. After melting, sprinkle in the flowering daffodil basin, which can extend the time of the narcissus period for about a week.
Increasing method: When the water fairy flower is about 25 cm in height, the water solution of the edible pigment that is steamed with the steamed pastry is used to inject the water solution of the steamed pastry into the stem.Essence
Prevent rotten roots: First of all, the roots will not be dry if the water is empty at night.Yushu yellow hair softness: need to change the water frequently.To keep the water cleaning, it is best to change the water once every 2-3 days to prevent root rot.soft toothbrushes can be gently brushed with soft toothbrushes.
9. Refrigerator control flower
The narcissus is cold and fear of heat. The suitable temperature during the growth period is 8 C to 12 C. After flowering, the temperature is required to be lower.If the temperature is low after flowering, the flowering period is long, and vice versa.If you want to extend the flowering period, you can put the narcissus in the refrigerator.
According to observations, when the room temperature is above 23 C, the flowering period of the aquaear in the aqua is one week; when the flowering period is about 10 days when the flowering period is about 10 days; the flowering period can be extended to 15 days to 20 days when 8 C to 12 C.Therefore, as long as there is a certain low -temperature environment, the flowering period of the narcissus flower can be effectively extended.
When the daffodil buds are opened, you can remove the flower ball from the pot, put it in a small plastic bag, put it in the refrigerator to store indoors, and take it out for a few days and put it in the Flower pot to continue to maintain it.The narcissus flower head (flower cricket) can also be refrigerated. When the first flower of Narcissus flower is opened, cut the flower cricket, insert it into the water cup, put it in the refrigerator, keep the temperature from 1 C to 3 C, and can be placed for 2 to 3 weeks.After taking it out, you can continue to bloom in the vase.
In addition, add a quarter of aspirin with 0.3 mg of aspirin in the narcissus Flower pot, which can also extend the flowering period and delay the withering of the flowers.
Frequently problem handling
Breeding method
Side ball breeding
This is the most commonly used breeding method.storage balls are born on both sides of the bulb ball. Only the base is connected to the mother ball. It is easy to break away from the mother's body. It is separated from the mother ball in autumn to plant it alone and produces a new ball in the next year.
Side bud reproduction
The side buds are buds wrapped inside the bulb ball.Only when the ball root is castration, it will be separated from the mother's body with the broken scales dug out, picking the white buds, sprinkled on the seedbed in autumn, and a new ball is generated the following year.
Double -scale reproduction
A bulb ball contains a lot of side buds, which are obviously visible and hidden.But its basic law is two spots of two scales.The breeding material with two scales with two scales is called double -scale breeding.The method is to put the bulbs at a low temperature of 4-8 weeks at a low temperature of 4-10 C, and then cut the bulb plates in the normal temperature, so that each piece with two scales, and remove the upper end of the scales and leave 2 cm for reproductive materials.Then use plastic Bags to contain 50%of vermiculite or 6%water with water, put the breeding material in the bag, close the closed bag, and place the dark place in the temperature of 20-28 C.Small bulbs can be grown through from February to March, with a ball rate of 80-90%.This is a new method that has begun to develop in recent years. It can be carried out in four seasons, but it is better to take April-September.The survival rate after transplanting the generated small bulb can reach 80-100%.
Organize
Use the MS medium, add 30 grams of sucrose and 5 grams of activated carbon per liter, use the bud tip as an external implant, or use a stem plate with double-scale stems to be 5 10 mm as an external implant with a pH value of 5-7; load it into;Among the 20X100 mm glass Tube, 10 ml of medium per pipe, after disinfection, implant an outer implant per pipe, and then cultivate in 25 C. After 10 days of vaccinationTurn into a medium containing NAA0.1/mg 1/2ms. After 6-8 weeks, leaves and roots are transplanted in the field, which can survive 100%.Use the tip of the stem as an external implant, as well as the effect of removing the virus
Prevention and treatment of pests and insect pests
The main pests of daffodils include large brown spot disease, leaf blight, nematode disease, mold, and penico.
Brown spot
Mainly harm the leaves and stems of narcissus.During the first dyeing, the leaf and the stalks occur in the leaf tip, brown, and large infections. Both the lesions and stalks will cause the leaves to distort the plants to stop growing, causing death.In the early stage of the onset, 75%peribilobacterium cleaner wettable powder 600-700 times aquatic solution, sprayed every 5-7 days, and sprayed several times to control the development of the disease.Dip off the membrane scales before planting, place the bulbs in a 0.5%Forma solution, or soak in a 50%multi -bacterial spirit 500 times aqueous solution for half an hour to prevent this disease.
Dead leaf disease
Most of them occur on the daffodils. When the first section is, it is a green macular, and then it is expanded in the fan shape. There is a yellow -green halo around the surrounding area. In the later period, the leaves are dry and black granular.This disease can be stripped off before planting and dried scales, and was washed 2-3 times with rare high manganate.At the beginning of the disease, it can be sprayed with a 50%Daisen zinc 1500 times aqueous solution.
Nematode disease
Mainly harm the leaves and flower stems of narcissus.At the beginning of the hair, yellow -brown inlaid stripes will appear on the leaves and stems of the daffodils, and then blisters or wave -shaped bulging will appear, causing the leaves and stem epithelium to break and brown until it wither.This disease can be prevented by soaking the bulb of 40-43 C for 3-4 hours.If plants are seriously found in the maintenance process, they should be removed and destroyed immediately.
precautions
1. Daffodil flower is more cold -resistant, so it is called "flowers in the snow".The critical crime of cold resistance is -3 C. By -3.5 C, leaf frostbite occurs.
2. In order to maintain a suitable temperature, you can use light adjustment.It is best to have a few hours of light (in order to prevent sunburn rooting, the root can cover a layer of cotton) to promote good growth.In the case of severe cold, when the temperature is very low, you can take a plastic bag, the bag is facing up, put the narcissus pelvis (put an appropriate amount of water in the pot), and then blow the plastic bag.To form a small small greenhouse, you can resist the cold wave.You can also use methods such as warm water to increase temperature.
3. Pay attention to changing water during the breeding process, especially when the night temperature is above 10 C, you must change the water frequently to prevent the roots from worsening the water quality.
4. Control the flowering time.Under the condition of sufficient light and cleaning water, when the indoor temperature is 12-15 C, it takes about 40 days from soaking to flowering; the room temperature is about 18 C, which takes about 30 days; when the room temperature is 20 C, only 25 will need to be 25 when it is 20 C.The sky blooms.Forever you need any flower Fertilizer, only water can be used.
5. You must pay attention to the selection of breeding balls. Mainly pay attention to the three main points of looking at shape, coloring, and pressing sensation.
Look at the shape: High -quality narcissus bulb, general individuals, flat, hard, and hard -quality, the longitudinal pulse stripes are wide, the middle membrane is tight, the Skin is bright, the root plate is wide and thick, and the main ball is symmetrical.bulb;
Viewing color: From the appearance, the ball stems are dark brown, the envelope is intact, the color is bright, the traces of no dryness, and the traces of insect pests are the top grade;
Pressing: Pressing is the main method of choosing and identifying how much daffodils and arrows. You can use your thumb and index finger to hold the ball stems, and press it slightly. The feel contour is columnar, elastic, and relatively solid., elasticity is slightly worse, most of them are leaf buds.
6.Correctly choose hydroponic or soil cultivation to cultivate narcissus.The hydroponic method is cultivated by light basin water.Put the daffodils that are treated by germination in a shallow basin of narcissus. It is advisable to add water to a third of the bulbs. The lithoscopy, pebbles, etc. can be fixed with quartz sand and pebbles.Move into the room and pour the water in the basin to control the length of the leaves. Add water the next morning. Be careful not to move the direction of the bulb. During the water fairy water, you must give sufficient light.It can be placed under the light in the evening, which can prevent the stems and leaves of the narcissus, which makes the narcissus leaves short, wide, strong, thick and green, thick flowers, and water fairy. Generally, it is not necessary to fertilize.For a little quick -acting phosphorus Fertilizer, the flowers can be bloomed better. As long as you have the conditions for the maintenance of narcissus, you can "flow with people"; otherwise, it will be postponed, and even long leaves will not bloom.
