Cultivation and maintenance of Luoshenhua

There are many kinds of flowers, and different flowers differ greatly in shape, color and aroma. The common flowers are roses and lilies. These flowers are very common, and they are also women's favorites. In particular, roses represent love, and different numbers of roses are different in meaning, so pay attention to this when buying flowers. What is Luoshen flower?

What is Luoshenhua:

Rose eggplant (scientific name: hibiscus sabdariffa linn.) Mingluoshenhua, Luoshenkui, etc., belong to Malvaceae, Malvaceae-annual erect herbs, 2 m tall, petiole 2-8 cm long, sparsely villous; Calyx cup-shaped, lavender, ca. 1 cm in diam., flowers yellow, capsule ovoid, ca. 1.5cm in diam., densely hirsute, valves 5; flowering.

Growth habit

Rose eggplant is a tropical and subtropical short-day crop, which likes light, temperature and avoid early frost. it grows best under the condition of 25 ~ 30 degrees Celsius. Roselle is sown from March to May and harvested from September to November. The whole growth period is 160-200 days, and the effective accumulated temperature is about 500-550 degrees Celsius. There are certain requirements for temperature, humidity, light, soil conditions and so on.

Soil

Rose eggplant belongs to straight root system, with developed lateral roots, deep roots, drought tolerance and waterlogging tolerance and wide adaptability. It grows well in sandy loam and ph6-8 soil with medium or lower fertilizer; the fertile land has many branches, sepals are thick, and the yield is high, but it is easy to grow and lodge and affect the yield; if the soil is too thin and sticky, it is easy to produce physiological diseases such as albino seedlings. During the growing period, poor drainage is prone to root rot, root rot and death. In case of overcast and rain during harvest, the calyx is easy to mildew, which directly affects the yield and quality. What matters should be paid attention to in family cultivation of daffodils (key points of daffodils maintenance)

It is said that daffodils are the embodiment of Emperor Yao's daughter E Huang and Nu Ying. They both married Shun, the elder sister was the queen, and the younger sister was the concubine, and the three had a very good relationship. Shun died in the southern patrol, and the Emperor and female Ying both died in love in the Xiangjiang River. God had mercy on the two and turned their souls into riverside daffodils, and they also became the flower gods of the December daffodils. On this basis, predecessors did not know to write many poems praising daffodils, such as Cao Zhi's Fu of God Luo and Fu before and after daffodils in the Song Dynasty. If they express the beauty of daffodils to one point, it is "purity". Today we will talk about the points for attention of daffodils.

Prevent "dumb flowers"

The so-called "dumb flower" refers to the phenomenon that the scape of the daffodil dies in the middle of the water culture, the bud withered or the bud decayed before it opened. The phenomenon of "dumb flowers" is mainly caused by the following reasons:

(1) the quality of daffodils is poor. The sphere is small, the flower bud is dysplastic, the sphere suffers from diseases and insect pests, the root disc is dry and decayed, the hairy root is few, and the physique is weak.

(2) improper maintenance. Lack of frequent change of water, lack of light, high room temperature and poor ventilation, resulting in long leaves and thin scape. In addition, the damage to the root and scape during the change of water will also lead to "dumb flowers".

(3) improper aquaculture season. If Frosts Descent's former bulb is in a dormant period or when the temperature rises after the Qingming Festival, there will be "dumb flowers". To prevent "dumb flowers", we should first select three-year-old high-quality bulbs for water culture. It is best to use Rain Water or pond water. If tap water is used, it should be stored for one day before use. Then it is necessary to ensure that the daffodils have sufficient light, not less than 6 hours a day, and pay attention to indoor ventilation. The temperature is kept at 12-15 degrees, which is most conducive to the growth of daffodils. In the north, the weather is dry and water is sprayed on daffodils every day.

Control florescence

The florescence of daffodils is earlier than peaches and plums and later than plums. Generally, water culture begins in autumn and winter, and it can blossom in winter and spring. So, how can we make the daffodils blossom during New Year's Day, the Spring Festival? This goal can be achieved by artificially controlling the period of daffodils.

In general, daffodils can blossom as scheduled after 45-50 days of water culture. The so-called normal aquaculture, that is, to ensure that after daffodils aquaculture, there should be 6 hours of light every day, and it is appropriate to keep the room temperature at about 10-15 degrees. If the weather is abnormal, the light is insufficient, and the temperature is too low (or too high), measures should be taken to make the daffodils blossom as scheduled.

Common methods:

When the ① temperature is too low and the light is insufficient, you can replace the daffodil basin with warm water of 12-15 degrees; surround the daffodil basin with plastic film at night, and use 60 watts of light 40-50 cm away from the flower to increase the temperature and strengthen the illumination. At the same time, spray water to the leaves of daffodils to prevent the temperature from rising suddenly. When the ② temperature is too high, add an appropriate amount of cold water to the daffodil basin, pour out the water in the basin at night, and carry out low temperature treatment, which can delay the narcissus flowering.

To prevent excessive growth

If you want to cultivate daffodils with short leaves and long pedicels, the key is to promote pedicel growth and avoid excessive growth of leaves. When raising daffodils in water, first remove the brown envelope on the appearance of the daffodils, cut longitudinally between the buds in the upper part of the daffodils, cut through 3-4 layers of scales, and then cut horizontally on both sides, do not hurt the flower buds, wash off the mucus, and culture them in a shallow basin.

Put it in a sunny place during the day, pour the water out of the basin at night, and then add water to cultivate it in the morning the next day, so as to avoid the excessive growth of leaves.

It can also be cultivated in the ground or potted first, and then raised in water to achieve the effect of short leaves and long pedicels. The specific approach is to first plant the daffodils in sunny places, water them every day until the pedicels are drawn, then dig out the daffodils, wash the soil, and keep the water indoors to watch.

Tips

① aspirin can help daffodils bloom

Use 1 to 2 aspirin tablets and dissolve them thoroughly in water to replace the water in the daffodil pot to make the flowers stronger and luxuriant.

② Narcissus warming to promote flowering

Daffodils grow slowly at low temperatures, and can be induced to blossom by warming:

Sun warming: transfer to outdoor sunlight during the day, or in front of sunny windows facing south indoors, until flowering.

Lighting warming: cover the flowerpot with a plastic cover, turn on the light, and wait for the cover to heat up to 23 ℃.

Electric heater heating: turn on the electric heater or place the hair dryer in a position not to scald the daffodils and let the warm wind slowly blow the flowers for several days until the flowers bloom.

Warm water: put a small amount of warm water in the basin to raise the water temperature to 12: 15 ℃.

③ salt prolongs the period of daffodils

When the daffodils are all in full bloom, put a small amount of salt into the basin to prolong the flowering period. Do not put salt when the daffodils are budding, otherwise it will inhibit the opening of the buds. Or grind two aspirins into powder, put them in 1000 milliliters of water, dissolve and sprinkle them in the blooming daffodils basin, which can prolong the daffodil blooming period by about a week.

④ brightening method

When the daffodils grow to a height of about 25 cm, the aqueous solution of food pigment steamed from pastry is injected into the stem with a medical syringe, and the injection point is the upper 1cm of the stem height.

⑤ prevents rotting roots.

First of all, if the water is empty at night, the roots will not dry up. The hair root is yellow and soft: change the water frequently. Daffodils to keep the water clean, it is best to change the water every 2-3 days to prevent root rot. Soft toothbrushes can be used for yellowing.

This is all I know about Narcissus. I hope it will be helpful for flower friends to read this article. If you want to know more about aquatic flowers, please continue to pay attention to succulent flower beds. We will provide you with more related knowledge!

Daffodils how to protect daffodils, also known as scallions, garlic, daffodils and so on. Because it is mostly raised by water, and the leaf posture is beautiful, the fragrance of flowers is rich, and it is graceful in the water, so it has the nickname of "Lingbo fairy". Daffodils are mainly promulgated in the warm and humid areas of the southeast coast of China, with Zhangzhou, Xiamen in Fujian and Chongming Island in Shanghai being the most famous. Narcissus belongs to the genus Amaryllidaceae, which is native to China. It has been cultivated in China for more than a thousand years and is one of the traditional famous flowers in China.

There are two words in daffodil language: one is "purity". The second is "auspicious". It is said that daffodils are the embodiment of Emperor Yao's daughter E Huang and Nu Ying. They both married Shun, the elder sister was the queen, and the younger sister was the concubine, and the three had a very good relationship. Shun died in the southern patrol, and the Emperor and female Ying both died in love in the Xiangjiang River. God had mercy on the two, so he turned their souls into riverside daffodils, and they also became the flower gods of the wax moon daffodils. On this basis, predecessors did not know to write many poems praising daffodils, such as Cao Zhi's Fu of God Luo and Fu before daffodils to Houbin, which was as high as Sun's in the Song Dynasty. If they express the beauty of daffodils to one point, it is "purity". It is said that in Yuanshan, Fujian Province, there was a kind peasant woman who relieved the hungry beggars who were dying. The beggar, who was originally a fairy, sprayed his meal around the house, and later grew Jinzhan Yintai daffodils. The meaning of giving daffodils in the folk is to praise your good heart and have good luck. Congratulations on your good luck and all the best. In the West, the free translation of daffodils is "love shadow flower", flower language is faithful love, extension is introspection to the sincerity of love. Narcissus is a perennial herb, bulb hypertrophy, globular, covered with brown skin film, white fleshy root at the base of the stem. The leaves of daffodils are extracted from the green-white tubular sheath at the top of the bulb (commonly known as arrow) and then extracted from the leaves. Generally, each bulb can draw 1-2 branches of flowering stems, up to 8-11 branches, umbels. There are mainly two varieties of Chinese daffodils: (1) single petal: single flower, white, perianth 6-lobed, with a golden annular crown in the center, so it is also known as "wine cup daffodil"; if the crown is white, with many flowers and thin leaf tips, it is called "Yinzhan Jade platform". (2) double petal: double, white, perianth 12-lobed, rolled into a cluster, called "narcissus" or "jade exquisite", the flower shape is not as beautiful as the single petal, the aroma is also poor, it is a variety of daffodils. Carving the daffodil ball is a traditional artistic technique in China. Crab claw daffodils carved by hand, leaves and pedicels curled, like crab claws, so it is called crab claw daffodils. Carving crab claw daffodils has to go through four processes: peeling scales, carving leaf bracts, cutting leaf edges, and carving flower stalks: (1) peeling scales: first scrape off the soil and withered roots on the head of daffodils and peel off the brown skin. Cut in with a knife along an arc parallel to the bottom at the bulb 2 / 2 or 1 / 2, peeling off the scales of the upper 2 / 3 layer by layer until the leaf buds come out. (2) carve leaf bracts: cut off the scales and leaf bracts on both sides of the leaf bud with a knife, be patient and meticulous, and do not hurt the leaf bud. When the leaf buds on both sides are curved, or when the two buds are too tight, you can use your fingers to gently support the soft leaf buds, and then slowly carve out the middle scale. The leaf bud is also covered with a layer of smooth scales. be careful to peel it so that the whole leaf bud is exposed. (3) cutting edge: the leaves of daffodils grow straight. If you want to make the leaves and pedicels grow into curved crab claws, you must cut them. When cutting the leaf edge, use your fingers to apply a little pressure from the back of the leaf bud to separate the flower bud from the leaf bud, and then cut off the leaf edge from the top to the bottom, from the outer leaf to the inner leaf averagely. After carving one side of the tissue is injured and scarred, the growth is slow, the uncut side is still strong, and the growth of the two sides is unbalanced, so it grows into a crab claw-like leaf bent to one side. During operation, do not touch the bud in the middle of the leaf bud. (4) carved pedicel: the upper part of the flower bud is the bud and the lower part is the pedicel. It is difficult to carve a flower stalk and cannot break the bud. When carving a pedicel, cut off the pedicel from top to bottom to a depth of about 1 pedicel. If you want the pedicel to bend in which direction, cut which side of the pedicel. The florescence of daffodils is earlier than peaches and plums and later than plums. Generally, water culture begins in autumn and winter, and it can blossom in winter and spring. So, how can we make the daffodils blossom during New Year's Day, the Spring Festival? This goal can be achieved by artificially controlling the period of daffodils. In general, daffodils can blossom as scheduled after 45-50 days of water culture. The so-called normal aquaculture, that is, to ensure that after daffodils aquaculture, there are 6 hours of light every day, room temperature at about 10-15 degrees is appropriate. If the weather is abnormal, the light is insufficient, and the temperature is too low (too high), measures should be taken to make the daffodils blossom as scheduled. Common methods: when the ① temperature is too low and the light is insufficient, you can replace the daffodil basin with warm water of 12-15 degrees; surround the daffodil basin with plastic film at night, and use 60 watts of light 40-50 cm away from the flower to increase the temperature and strengthen the illumination. at the same time, spray water to the leaves of daffodils to prevent the temperature from rising suddenly. When the ② temperature is too high, add an appropriate amount of cold water to the daffodil basin, pour out the water in the basin at night, and carry out low temperature treatment, which can delay the narcissus flowering. To prevent the excessive growth of leaves and root rot, first of all, if the water is empty at night, the root will not dry up. The hair root is yellow and soft: change the water frequently. To keep the water clean, daffodils had better change the water every 3 days to prevent root rot. Soft toothbrushes can be used for yellowing. The following is how to cultivate daffodils with short leaves and long pedicels: if you want to cultivate daffodils with short leaves and long pedicels, the key is to promote pedicel growth and avoid excessive growth of leaves. When raising daffodils in water, first remove the brown envelope on the appearance of the daffodils, cut longitudinally between the buds in the upper part of the daffodils, cut through 3-4 layers of scales, and then cut horizontally on both sides, do not hurt the flower buds, wash off the mucus, and culture them in a shallow basin. Put it in a sunny place during the day, pour the water out of the basin at night, and then add water to cultivate it in the morning the next day, so as to avoid the excessive growth of leaves. It can also be cultivated in the ground or potted first, and then raised in water to achieve the effect of short leaves and long pedicels. The specific approach is to first plant the daffodils in sunny places, water them every day until the pedicels are drawn, then dig out the daffodils, wash the soil, and keep the water indoors to watch. How to deal with flowering daffodils after the Spring Festival, the daffodils withered. Usually people will throw away the daffodils that have bloomed, which is a pity. Narcissus is a perennial plant, it is raised by bulbs, if those flowering bulbs are buried in the soil, it can continue to grow and cultivate. Choose the vegetable garden or nursery land with leeward to the sun and deep soil layer, and build a high ridge after deep ploughing and raking, and trench on the ridge, in which the flowering bulbs are buried, and the leaves are preserved naturally. A month later, the leaves withered and dormant, at this time to dig up the bulb, cut off the fibrous root, and cut off the withered and yellow leaves along the base, and then bury the bulb at a depth of 10 cm, while applying rotten cake fertilizer or human feces and urine, and then rake flat. You can't save trouble and bury things in the flowerpot, because the bulbs have to spend the long seasons of spring, summer and autumn in the soil, especially in summer and autumn, when the heat is hot, the bulbs are buried in them, and there are no leaves on them. If you forget to water and fertilize them, it will cause drought and death. After dealing with the bulb, the following work is the daily maintenance and management, usually as long as pay attention to give sufficient nutrients to the garden, while keeping the garden moist but without stagnant water, the bulb can grow naturally. Wait until November or December, and then dig out the bulb, then you will find that the old bulb is rotten and empty, but there are many bulbs large and small around it. Pick out those bulbs with many large buds, wash the soil above, peel off the brown skin film on the surface, and then leave them in the sun for a few hours, then use a knife to make a "ten" cut at the top of the ball, with a depth of no harm to the bud eyes in the scale. grow out with sharp buds and leaves. Soak in clean water for 24 hours, wash the gelatinous mucus from the incision, and then carry on the normal aquaculture. Generally 3 days later, the white fibrous root can grow at the bottom of the ball, and the bud eye at the top of the ball will gradually sprout leaves. As for those small bulbs, because they would not blossom that year, they were allowed to grow in the soil for another year, and then dug up for aquaculture the following year.
