How to cultivate delphinium, cultivation methods and precautions of delphinium/sufficient light

Delphinium is a kind of highly ornamental flower plant, and there are many people who raise it in our country, but there are many places that need to be paid attention to. How to raise delphinium? What are the breeding methods and matters needing attention of swallows? Next, the editor will take you to learn about it.

First, how to raise delphinium

2. Breeding methods and matters needing attention of delphinium

1. Soil requirement

Among the breeding methods and matters needing attention of delphinium, the selection of soil is a step to lay a good foundation. Generally, it is best to choose a more fertile humus soil, which has good drainage and air permeability and can better absorb nutrients and grow more healthily.

two。 Fertilization requirements

Fertilizer is one of the main nutrients in the growth process of delphinium, and its demand for fertilizer is relatively large. Basically, it needs to be fertilized once or twice a month, but when applying fertilizer, we should remember that fertilizer should be diluted first, so that it can be better absorbed. If it is not diluted and thick fertilizer is applied directly, it is easy to burn the plant and cause the leaves to turn yellow.

3. Watering management

In the process of breeding delphinium, watering is also a very fastidious thing, not too much nor too little, it is best to maintain the principle of seeing dry and wet, watering should be thoroughly watered once, but remember not to cause stagnant water, otherwise it is easy to cause rotting rot. as a result, there are still a lot of places that need to be paid attention to in the breeding methods and matters needing attention of delphinium.

4. Light management

Delphinium is a kind of light-loving plant, so the requirement for light in the process of growth is still very high, it is best to keep sufficient light, so that it can better carry out photosynthesis, so as to lay a good foundation for flowering.

5. Pest control

In the process of delphinium aquaculture, if it is not operated properly, it is easy to have such phenomena as diseases and insect pests, which do great harm to delphinium, not only affect its beauty, but also easily lead to plant death if not in time. As for the specific treatment methods, you can refer to the article on pest control of delphinium, which is introduced in detail.

Planting methods and matters needing attention of delphinium

The flower shape of swallows is similar to that of swallows, and swallows are widely planted, which are common in grasslands and hillsides. Some friends will plant delphinium in pots, and then Xiaoqi will share the planting methods and precautions of delphinium.

First, the planting method of delphinium

1. Soil: slightly acidic sandy soil with rich humus, the pH value is best controlled at 5.5-6. Keep the soil moist and not easy to accumulate water. 6 to 9 weeks after germination, each seedling can be transplanted into a flowerpot with a diameter of 9 to 10 cm, or every 3 seedlings can be transplanted into a large pot with a diameter of 13 to 15 cm. Don't plant the plant too deep when transplanting.

2. Lighting: swallows need to receive enough sunlight to promote plant growth, especially in winter, tolerate certain shades, avoid strong light in summer and put them in semi-shady places. Like cool weather, the best growth temperature is between 20-25 ℃ during the day and 3-15 ℃ at night.

3. Watering: swallow grass likes to be moist and resistant to drought. When watering, it should be watered at once, dry, and the amount of water should be slightly increased during flowering, not too dry. When changing the basin, the base fertilizer needs to add dry manure, and in other periods, fertilizer should be applied according to the growth of the plant, generally applying cooked cake fertilizer and water 1 to 3 times a month.

II. Matters needing attention in the cultivation of delphinium

Delphinium needs a sunny and cool growth environment. It can tolerate both cold and drought, but it is not resistant to high temperature and moisture, and the requirement for soil is not very high. It can be sown in spring or autumn, and if sown in autumn, it must be in mid-September. The soil must be kept moist after sowing. The easiest way is to cover some grass and gradually remove the mulch after emergence. When Swift grass grows 2 true leaves, transplant it in a small basin with soil, and then change the pot once after the seedlings grow up.

Swallow watering should be dry and wet, and appropriate more water should be watered during the flowering period to avoid excessive dryness of the soil. Dry manure was applied as base fertilizer when changing pots, and then rotten cake fertilizer and water was applied one to three times a month according to the growth situation. After changing the basin, paclobutrazol was used to control the height of the plant, and 0.5% paclobutrazol was applied every 2 weeks. The seeds should be collected in time to avoid fruit cracking after ripening.

The above is the planting methods of delphinium and points for attention to share, hoping to be helpful to the friends who cultivate delphinium.

Delphinium grandiflorum delphinium: how to raise delphinium / how to propagate delphinium business card Delphinium grandiflorum the introduction of delphinium, a herbaceous flower belonging to Ranunculaceae in 2012. The plant type of delphinium is tall and straight, the plant height is 30 cm ~ 100 cm, and some varieties can reach 120 cm in height. There are sparse villi on the stems and leaves, the leaves are alternate, palmately parted to parted, and the lobes are linear; the basal leaves have long stalks and the upper leaves are sessile. The inflorescence of delphinium is a terminal raceme or spike, florets about 2.5 cm ~ 4.0 cm in diameter, sepals 5, pansy blue or pink, upper sepals long-spaced, petals 2, connate, the same color as sepals, outer sepals also petal-shaped, the same color as petals, the outermost one is narrowly oval. The florescence of delphinium is from May to August, and its flowers are rich in color, such as blue, light blue, white, pink, meat powder, etc., and most varieties have eye spots on their petals. At present, garden technicians have cultivated many hybrid varieties, such as beautiful delphinium, high delphinium and so on, which not only have richer flowers and colors, but also have many changes in flower pattern, which makes the family of delphinium grow up gradually. The swallows plant is tall and straight, the leaves are slender and green, and the flowers are dense and gorgeous. From afar, they look like birds playing with their branches. Morphological characteristics of swallow herbs annual, less than 1 meter tall, slightly hairy. A small number of branches are raised. Basal leaves long stipitate, 3-parted almost to base, lobes subdivided into many linear decimal segments; upper leaves sessile, also with numerous linear lobes. Racemes extremely long, thinly pilose; petiole raised, 1.5-4 cm long, with a pair of bracteoles at or below middle; flowers blue, bluish purple to reddish or white, often double, 2-4 cm in diam.; sepals 5, broad and slightly obtuse, posterior 1 extended into spur, spur upward curved, about as long as the rest of the flower, the upper 1 pair of petals is inserted into it; carpels 1, sometimes numerous in double flowers. Delphinium caryophyllum pod ca. 1 × 2 cm, hairy, apex pointed beak. Perennial herbs flowering from May to August, 35-65 cm tall. The whole plant is pilose. Stem sparsely branched. Leaves alternate, palmately parted, basal leaves and lower leaves of stem long stipitate; leaf blade round-reniform, trisect, 2.2-6 cm long and 4-8 cm wide, lobes lobed, lobules striate, 0.6-2.5 mm wide. Racemes with 3-15-flowered, rachis and pedicels retrorsely puberulent; flowers zygomorphic; bracteoles striate or subulate; sepals 5, petal-shaped, blue or purplish blue, 1.5-1.8 cm long, upper 1 spur, apex often retuse; petals 2, smaller, spur, spur protruding from calyx spur; staminodes 2, petals broadly Obovate, retuse, yellow bearded; stamens numerous; carpels 3, free. When the flowers are in full bloom, a flock of blue birds fall from the sky, which is very moving. The flowering period is from August to September and the fruiting period is from September to October. The wild species of delphinium are mainly produced in the temperate zone of the Northern Hemisphere. They like the growth environment with plenty of sunshine, good ventilation and smooth drainage, and are suitable to grow on fertile sandy soil rich in organic matter. Its cold tolerance and drought tolerance are strong, but it is not resistant to high temperature, so it should be moved to a cool place for cultivation in high temperature areas in summer. Delphinium likes cool climate. The optimum temperature is 20 ℃ ~ 25 ℃ in daytime and 13 ℃ ~ 15 ℃ at night. Appropriate amount of nitrogen fertilizer should be applied before flowering, and phosphorus and potassium fertilizer should be applied after flowering. The inflorescence of Swift grass used for cut flower cultivation is tall, so we should pay attention to prevent plant lodging, which can be fixed by pulling net between plants. Swallows are most afraid of flooding, so pay attention to drainage on rainy days. As the ripening period of delphinium is inconsistent, and it naturally cracks after ripening, and the seeds are easy to be lost, the distribution area of delphinium should be harvested in time, which is produced in China and Northwestern Asia, at an altitude of 700 meters. Its horticultural domestication began in the 17th century. With the characteristics of tall and straight plants, beautiful leaves, full inflorescences and dense flowers, it has become a "pretty woman" in European gardens and has been widely used in gardens. At present, delphinium is cultivated in all provinces of China, and there are even wild species of delphinium in Hebei and other places. Under the trend of vigorously promoting landscaping and beautifying the use of native flowers, it is believed that this beautiful flower will be more widely used. Cultivation techniques of swallow grass transplanting nursery bed preparation: select the plot with good light, drainage and soil pH6.0~6.5. Applying organic matter to the soil will help to improve soil structure and increase yield. Spacing: 20cm. It needs to be supported by a planting net. Fertilizer and watering: the appropriate soluble salt content is 1.0 to 1.4. Fertilizing with balanced calcium nitrate helps to promote plant sturdiness. Maintain appropriate humidity to avoid root damage caused by plant wilt, resulting in a decline in the quality of cut flowers. Long-day sunshine: long-day sunshine helps to promote flowering, resulting in shorter plants. Swift grass can be propagated by means of ramet, cutting or sowing. The suitable temperature for seed germination is about 15 ℃, and the soil temperature should be kept below 20 ℃, which generally germinates about two weeks after sowing. The autumn sowing is from late August to early September. First sow the seeds in the open field seedbed, then move the seedlings to the cold bed or cold room to survive the winter before winter, and then move to the outdoor planting after the spring weather turns warm. In the southern region, direct seeding can also be carried out in the open field in early spring, and the seedling spacing can be maintained at 25 cm ~ 50 cm after emergence. Generally, the seedlings can be planted when they grow 4 ~ 7 true leaves. Cuttage propagation is generally carried out in spring. When the new tip grows more than 15 centimeters, cut the cuttings and insert them into the sand. Ramet propagation can be carried out in spring and autumn. Cultivation temperature: 15 mi 20 degrees; growth temperature: 15 mi 24 degrees. Cold treatment ahead of time: cover the seeds with a small amount of vermiculite after sowing to the hole plate, requiring suitable dry humidity of the substrate and no pathogens, pH of 5.5 Mel 6.3, poured thoroughly with chlorazophos and water to prevent the occurrence of diseases and insect pests. Put the seedling tray in the dark at a low temperature of about 10 degrees for 15 seconds for 20 days. Pay attention to keep the substrate of the seedling tray moist and can be covered with plastic film. Stage 1: move the seedling tray to a bright greenhouse and keep it 20 degrees during the day and 15 degrees at night for 12 hours. In order to maximize its germination rate, try to keep the temperature no higher than 25 degrees during the day and 20 degrees at night. Stage 2: when the seeds begin to germinate, the balanced nitrogen fertilizer containing Ca is mixed into 75-100ppm for application. Put the seedling tray in a cool and transparent greenhouse and keep the temperature at 15 degrees Celsius. Pay attention to the circulation of air. High temperature at seedling stage (higher than 25 degrees Celsius) will lead to early flowering and poor quality of cut flowers. Low temperatures (below 10 degrees) can lead to plant rosettes, which can be broken by increasing the length of sunshine from winter to spring. Stage 3: when the soluble salt content in the soil is 0.8 rain 1 and pH 5.5 is 6.3, the true leaves begin to form and the temperature is kept at 15-18 degrees Celsius. Colleagues provide a good air environment to prevent diseases. The leaves and roots of delphinium are susceptible to disease infection, so the early good environmental conditions and water quality are very important. Stage 4: (29-35 days) the seedling stage will reach the transplanting size and have 3 true leaves. Delphinium belongs to straight root system. Delayed transplanting will reduce the quality of plants and flowers. The dietotherapy or medicinal value of delphinium officinalis the medical information and health dietotherapy information of Huanhua net are for reference only and can not be used as the basis of diagnosis and medical treatment. Any health problems should consult professional health care personnel, the treatment of any disease, please follow the doctor's advice. The ultimate task of protecting flowers: to love yourself, proceed from reality and follow the doctor's advice. For disease, do not be careless, do not postpone, do not give up hope, face it bravely, warm the silent world with love, and protect the inner flower field with your heart. Note of traditional Chinese medicine: the Chinese herbal medicine delphinium and the above-mentioned plants belong to the same genus and different species. Alias: cat's Eye, Pigeon Flower, Swift Grass, Chicken claw Lotus, Tu Huang Lian [Jilin] Source: Delphinium grandiflorumL., of the genus Ranunculaceae is used as medicine with root, whole grass and seed. Collect the whole grass in summer, remove the soil, cut it to dry; pick roots and seeds in autumn and dry in the sun. The classics of nature and taste: bitter, warm. It's poisonous. Functional indications: purging fire and relieving pain, killing insects. Root: toothache. Whole grass: kill lice. Usage: wash with proper amount of fried water for external use, or make tincture for use. (note) the whole grass is poisonous, among which the seed is the most toxic, which mainly contains alkaloids, which can cause nervous system poisoning, dyspnea, blood circulation disturbance, muscle and nerve paralysis or spasm. Be careful when you use it. The above excerpt: the whole herb and seeds of the National Compendium of Chinese Herbal Medicine can be used as medicine to treat toothache. The extract of stems and leaves can kill insects. Roots and seeds: swallows, annual herbs, less than 1 m tall, slightly hairy. A small number of branches are raised. Basal leaves long stipitate, 3-parted almost to base, lobes subdivided into many linear decimal segments; upper leaves sessile, also with numerous linear lobes. Racemes extremely long, thinly pilose; petiole raised, 1.5-4 cm long, with a pair of bracteoles at or below middle; flowers blue, bluish purple to reddish or white, often double, 2-4 cm in diam.; sepals 5, broad and slightly obtuse, posterior 1 extended into spur, spur upward curved, about as long as the rest of the flower, the upper 1 pair of petals is inserted into it; carpels 1, sometimes numerous in double flowers. Cyanine pods ca. 1 × 2 cm, hairy, apex acute beak. The florescence is April. It is mostly cultivated in the garden. It is native to southern Europe and is cultivated in China. It is usually collected from July to August. [functional indications] seed: taken orally, the effect is similar to aconitum, and can treat wheezing and edema. Root: main treatment of abdominal pain. Medicinal prescription ① to treat wind-hot toothache: Swift grass five cents to one money. Water frying contains gargle, do not swallow. ("Handbook of commonly used Chinese Herbal Medicine in Northeast China") ② treatment of scabies: swallow grass mixed with Sophora flavescens. ("Handbook of Chinese Herbal Medicine at High altitude") ③ treats head lice: fresh chicken feet with whole grass, mashed and washed with water. (Jilin Chinese Herbal Medicine). Seven compounds were isolated from Delphinium grandiflorum L. By atmospheric column chromatography and thin layer chromatography. The structures of six compounds were identified by physicochemical properties and spectral analysis. They are: (1) 7-dimethoxy-5-hydroxyflavone (2) 1-methyloxy-5-hydroxyflavone (2) 1-methylidene O-demethylTalasamine (3) Methyl Niubianting (4) Tetrandramine (5) Tetrandrine (6) compound 1 was identified by literature search. (2) they were isolated from this plant for the first time. There are many kinds of traditional Chinese medicine collected, and the best harvest time is also different for different medicinal parts. The so-called best harvest time is aimed at the quality of traditional Chinese medicine. The quality of traditional Chinese medicine depends on the content of active components, and is closely related to the place of origin, variety, cultivation technology and harvest years, season, time, method and so on. In order to ensure the quality and output of Chinese herbal medicines, most of them should be harvested in time after maturity. The maturity of traditional Chinese medicine means that the medicinal parts have reached the medicinal standards and meet the provisions and requirements of the National Pharmacopoeia. The quality of medicinal materials includes internal quality and appearance characters, so the best harvest time of traditional Chinese medicine should be carried out in the period with the highest content of effective components and the best appearance traits such as shape, color, texture and size, so as to obtain high-quality medicinal materials and achieve better benefits. According to the previous experience, combined with the factors affecting the character and quality of medicinal materials and the law of storage and loss of nutrients in the process of growth and development of medicinal plants, according to the different medicinal parts of traditional Chinese medicinal materials, the best harvest time of traditional Chinese medicinal materials is briefly described as follows. 1. The varieties of traditional Chinese medicine used in root and rhizome are generally of good quality with root and rhizome fruiting, straight root, less bifurcation and powdery foot, and the harvest season is mostly in autumn, winter, or early spring. wait for its growth to stop, the dormant period of flower and leaf withering and before sprouting in early spring. Most varieties are harvested before germination in spring, because the medicinal plants are ready to germinate in early spring, and a large number of nutrients stored in the rhizome have not yet or just begun to decompose, so the content of effective components is the highest, the nutrients are the most abundant, and the quality is the best. However, there are exceptions, such as Radix Astragali, Polygonum multiflorum, Coptis chinensis, Codonopsis pilosula, etc. are harvested in autumn, while Radix Pseudostellariae, Pinellia ternata and Fuzi are harvested in summer with high content of active components and good quality. Second, the varieties of traditional Chinese medicine with flowers are mostly harvested when the buds are not in bud, and the quality is better. If the flowers are in full bloom, the flowers are easy to break, break, lose color, and the aroma escapes, which seriously affects the quality. For example, when honeysuckle changes from green to yellow in front of summer and autumn buds, when cloves change from green to red in autumn, when magnolia flowers do not bloom in late winter and early spring, when roses are about to bloom in late spring and early summer, and when flower buds are formed in summer, Sophora japonica is the most suitable for harvest, with high content of active components and good quality. However, there are also some varieties of traditional Chinese medicine that need to be harvested when the flowers bloom, such as when the rose flowers bloom slightly in spring and summer, sheep flowers bloom from April to May, foreign golden flowers bloom in spring and summer and early blossoms, chrysanthemums bloom in autumn and winter, and red flowers change from yellow to red in summer, which is the most suitable harvest time. 3. The varieties of traditional Chinese medicine with fruits and seeds are better harvested when they are naturally mature or near maturity, while seeds should be better harvested when the seeds are fully developed and mature, the seeds are full and the content of active components is high. Such as hemp kernel, aristolochia, skin seed, green box, Schisandra chinensis, nutmeg, semen Raphani, raspberry, papaya, mountain plant, Trichosanthes, bitter almond, plum kernel, Wumei, golden cherry, Astragalus, grass cassia, psoralea, fenugreek, Fructus Aurantii, Evodia, Croton, sour jujube, fat sea, big wind, make gentleman, river, fennel, snake bed, dogwood, forsythia, virgin, nux vomica, nux vomica. Dodder, morning glory, Tianxianzi, Chinese wolfberry, burdock, Coix seed, Amomum villosum, grass fruit, Yizhi kernel and so on. Varieties with inconsistent maturity should be picked along with maturity and carried out in batches at maturity. Such as impatience, daughter, and so on. 4. The varieties of traditional Chinese medicine with leaves should be harvested when the plant grows most vigorously, the flower is not in full bloom or the flower is in full bloom, when the plant has fully grown, the light and effect is exuberant, and the content of active components is the highest. Such as Daqing leaf, perilla leaf, Senna leaf, smelly sycamore leaf, moxa leaf and so on. The ripening period is inconsistent, and it should be naturally cracked after ripening, so it should be harvested in time. Generally, the ripe seeds will be harvested 1 or 2 times in June, and all the seeds will be harvested and dried in July. Rinse, cut and dry the whole grass. Biological identification shows that the root is cylindrical, 2-7cm long and 1-3mm in diameter; the surface is dark brown with obvious transverse lines; the folded section is yellow. Stem surface brownish yellow, angled, cross section hollow. Leaves wrinkled, yellowish green, wet and flattened and reniform pentagonal, 0.8-1.4cm long, 0.7-2.3 cm wide 3-cleft, central lobe broadly rhombic, lateral lobes nearly fan-shaped, first to second lobes narrowly ovate; petiole. Flowers solitary; bracteoles leaflike or elliptic; pedicels pubescent; sepals 5, blue-purple, broadly elliptic, spur cylindric-subulate, ca. as long as sepals; staminodes 2, petaloid, dark brown, 2-lobed, yellow bearded; ovary hairy. The length of follicles is about 1.8cm. Seeds obconical tetrahedral. The breath is slight and the taste is bitter. The function and use of swallow grass the landscape value of swallow grass flower shape is unique, the color is elegant. Or cluster planting, planting flower beds, flower borders, can be used as cut flowers, tall flower varieties or a good material for cut flowers. The whole grass is poisonous in industry, and the seed oil can be used in industry. The garden use of swallow grass is similar to that of birds, with large clusters of flowers and colorful flowers, such as blue, purple, white and pink. Dwarf species are suitable for potted plants or flower beds, and swallows are suitable for flower mirrors or green space planting in the garden. The cultural background of swallowgrass folklore it is said that a British hero Yaias, who was angry because he had received too little booty, stabbed and hacked at the flowers and plants in the courtyard with a sword. when he came to his senses, he was ashamed of this behavior and committed suicide. After the blood dripped to the ground, there was a beautiful delphinium, and it was said that the initials A ·I ·An of the English name of Yaias appeared on the flowers. Legend II A legend full of blood and tears spread among the folks of southern Europe. In ancient times, a group of people fled because they were persecuted, but unfortunately they were all killed. The souls one after another turned into flying swallows (a green Finch), flew back to their hometown, and hid on the weak grass branches. Later, these flying swallows turned into beautiful flowers, blooming in their native land year after year, eager to give them "justice" and "freedom". ★ severe warning: this plant is highly toxic, accidental eating may cause death or serious illness! The flower language of swallow grass is "Qingming Festival, justice, freedom", and the flower language of "light, beautiful, thin and short". Different designs and colors also have different meanings. Blue flowers represent depression, purple flowers represent admiration and gentleness, pink flowers represent poetic, white flowers represent elegance. Swallow grass pictures
