Dawang evergreen can be said to be a more common variety of evergreen, and because of its strong negative tolerance, it is also very suitable for raising indoors. Friends who like the king evergreen tend to breed at home. Generally speaking, the success rate of cutting propagation is higher. The editor will introduce you to three propagation methods besides cutting propagation. Interested friends can learn about it.

The king is evergreen.

1. Tissue culture and rapid propagation: this is a bioengineering method that can produce tissue-cultured Wannian seedlings in large quantities in a short period of time. The advantages are high speed, large quantity, not limited by climatic conditions, high uniformity of seedlings and quality assurance, but there must be special equipment and professional and technical personnel.

Second, the top insertion method: the top advantage of Dawang evergreen is obvious, but the natural germination power of lateral buds is poor. Cutting the top can promote the germination of lateral buds and greatly improve the reproduction coefficient.

Third, stem insertion method: take the old stem of the mother plant, cut every 3 nodes into one section, and apply the same rooting powder and charcoal powder to the incision. after the incision is cool and dry, put it flat on the seedling bed and bury it into the matrix 1 beat 3. After the seedlings grow, they can be dug up and planted.

In order to grow the king's evergreen well, we must pay attention to the following links in cultivation:

The cultivation medium requires good air permeability and water holding capacity, as well as fertility, and it is better to cultivate pond mud with good soil mixed particles. The pot capacity of potted plants should be on the large side, and the key points of annual cultivation and management are: preservation in winter, rapid propagation in spring, promotion of growth in summer and seedling training in autumn. Under the premise of sufficient moisture in spring and summer, from light to heavy application, mainly nitrogen fertilizer, with the principle of topdressing phosphorus and potassium. The proportion of nitrogen should be properly controlled at the end of autumn, mainly phosphorus and potassium. Pay attention to the prevention and control of aphids, aphids are the main pests of the king evergreen, generally cluster to damage heart leaves, can be sprayed with 1000 times omethoate solution. The leaves and stems of the king's evergreen leaves and stems are poisonous, and contact with the skin has an irritating effect. Attention should be paid to planting and placement to avoid accidental injury.

The cultivation method of evergreen photo album

Evergreen (scientific name: Rohdeajaponica) is the only species under the genus evergreen, is a perennial evergreen herb, also known as Jian, thousand-year-old, open throat sword, Jiujie lotus, winter does not wither, winter does not wither grass, iron pole, ebony venom, white sand grass, chopping snake sword, etc., originated in southern China and Japan, is a very popular excellent ornamental plant, in China has a long history of cultivation.

Morphological characteristics

Perennial evergreen herbs, without stems above ground. The rhizome is thick and short, yellowish-white, articulate, with many slender fibrous roots on nodes. The leaves are clustered from the rhizome, thick, lanceolate or banded, 10-25 cm long and 2.5-5.5 cm wide, with the edge slightly pleated, the base narrowing to the shape of a petiole, dark green above, light green below, many parallel veins straight out, and the main vein thicker.

The berry is globose, orange-red; contains 1 seed

The common varieties are:

1. Evergreen in Phnom Penh (var.marginata).

two。 Silver evergreen (Var.variegata).

Others are large leaves, fine leaves, dwarfs, and varieties with yellow and white markings, more in Japan and Taiwan. Place of Origin

Wannianqing originated in China and Japan. It is widely distributed in China, including East China, Central China and Southwest China, and the main producing areas are Zhejiang, Jiangxi, Hubei and other places. Habitat habit

Like to grow in wet places under the forest or in the grass.

Sexual preference for semi-shade, warm, moist, well-ventilated environment, not drought-resistant, slightly cold-resistant; avoid direct sunlight and stagnant water.

The general garden soil can be cultivated, but the slightly acidic sandy loam rich in humus, loose and permeable is the best.

Habitat

It grows in moist areas of forests and grassy slopes at an altitude of 700 mi 1700 m. Naturally distributed in China's Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Shandong, Sichuan, Zhejiang and Japan's Honshu, Kyushu, Shikoku. [1]

Medicinal use

Evergreen contains evergreen glycosides (Rhodexin A, B, C, D), which has cardiotonic and diuretic effect, but it is toxic, and overdose will endanger life, so it should be used with caution. [6]

Evergreen can also be used as a traditional Chinese medicine for heat-clearing medicine. in the New compilation of Materia Medica, the roots and leaves of evergreen can be used as medicine, which can strengthen heart and diuresis, clear heat and detoxify, cool blood and stop bleeding, and the medicinal properties are bitter, sweet, cold and slightly toxic. Can be used to prevent and treat diphtheria, diphtheria caused by myocarditis, sore throat, and adverse urination and other diseases. [7] [8] however, evergreen has a certain toxicity and will produce digitalis-like effect, so we should pay attention to the dosage when using it.

Cultivation

Evergreen likes warmth and humidity, waterlogging and semi-shade, not drought, semi-shade, sun exposure, cold tolerance, slightly fertile weak acid soil, but neutral and weakly alkaline soil can also grow, so a little fertilization can be applied.

Evergreen can be propagated by ramet or sowing, which is best in spring and autumn. If sowing, the fleshless seeds will be planted in the soil from March to April to keep the soil moist. The suitable temperature is 2030 ℃, and it can germinate after about 30 days. Evergreen is easy to cultivate, has strong adaptability, a small amount of fertilization, pay attention to shade, pay attention to ventilation, pay attention to the temperature of its environment above 0 ℃ in winter, it can grow well.

Dieffenbachia

[alias] Dai Fan Ye.

[scientific name] Dieffenbachia maculata

Araceae (Araceae), Daifen.

Perennial evergreen herbs. The stem is stout and succulent, and the plant height can reach 1 meter. The leaf is large and bright, born on the upper part of the stem, elliptic-oval or broad slope needle-shaped, apex acuminate, entire, 20-50 cm long, 5-15 cm wide, dark green on both sides of the leaf, inlaid with dense, irregular white, milky white, yellowish and other color spots, markings, patches. Common horticultural varieties are Dawangdai powder leaf, Baiyudai powder leaf, summer white powder leaf and so on.

[habits] native to tropical America. Like high temperature, high humidity, semi-shade or shade environment. Not cold-resistant, avoid strong light, requires loose, fertile, well-drained sandy loam.

[propagation] mainly by cutting. Cut off the small plant from the base of the plant from April to May in spring, dry the wound slightly, or touch the wound with plant ash and insert it into plain sandy soil. pay attention to shading and moisturizing, and it can take root in about 1 month.

[cultivation] 2 parts of rotten leaf soil, 1 part of garden soil and 1 part of river sand plus a small amount of mature basal fertilizer were used as culture soil. In order to keep the basin soil moist in the growing season, we should water more, rather wet than dry, supplemented by foliar spraying. Control moisture in autumn, dry and wet; pay attention to make basin soil dry in winter. Fertilization during the growing period is generally once a month, usually to prevent direct sunlight, to be shaded. Change the basin once a year in spring. The winter overwintering temperature should not be lower than 10 ℃.

Water: like wet water, more watering should be done during the growth period from March to August. It is necessary to sprinkle water frequently in summer to increase environmental humidity.

Temperature: like high temperature, not cold-resistant, the suitable temperature for growth is 20ml / 30℃. The lowest overwintering temperature is above 12 ℃. Once frozen, the leaves will wilt and the terminal buds will die.

Fertilizer: during the growing period, nitrogen fertilizer was applied every month to promote its rapid growth, and fertilizer and water were applied every two weeks from March to August. Reduce fertilization after autumn.

Soil: soil that requires loose, fertile and well-drained soil.

Propagation: cuttage propagation. It can be carried out in spring and summer. Take 10 Mel 15 cm long twigs, insert them into the yellow sand medium, take root in 20 mi 30 days, and then change them into a new pot depending on the size of the plant.

Ornithogalum caudatum

Jane introduced Tiger Eye evergreen is native to southern Africa. Like the sun, but also resistant to semi-shade, cold-resistant, afraid of direct sunlight in summer, good humid environment, leaves are still green after heavy frost in winter. The bulb has the habit of dormancy in summer, the bulb has strong meristematic ability and high reproduction coefficient.

Multiplication is often used to divide balls and sow and reproduce. The bulbs were dug up from August to September and planted according to their size. After a few years of planting, the bulbs were divided into bulbs when the bulbs were crowded. Sowing and propagation, seedlings need to be cultivated for 3-4 years before they can blossom.

The cultivation is robust and resistant to extensive management. fertilizing once a month, the soil should be loose, moist and well drained. The residual pedicel should be removed after flowering, and the flower will bloom more in the following year. The storage temperature of the bulb is 25 ℃ and needs to be dried and ventilated.

Diseases and insect pests have the harm of mosaic disease, and the virus is transmitted by aphids, which can be sprayed and controlled by 2.5% fish rattan essence 800 times.

Is an evergreen perennial herb. The leaves are lanceolate, green on the front, with different shades of stripes, purplish red on the back, and purplish red stripes on the back (see photo). The stems and leaves are slightly juicy. The flowering period is from August to October and it is easy to seed. Floret white, because the flower is born in the purplish red two clam-shaped bracts, its shape is similar to the clam shell to spit beads, so it is also called "clam flower".

Its leaves have different colors on both sides, green and bright changes, moderate plant shape, graceful posture, red bracts contain many jade and white florets, color contrast is obvious, strange and interesting, showing the scene of beads spitting from clam shell, which is very rare and never tired of seeing.

Purple back young people like semi-shady, humid environment, like fertile, loose sandy loam, more resistant to drought, afraid of exposure, afraid of cold, stop growing at 10 ℃, so it is better to overwintering more than 10 ℃.

It has good shade tolerance and strong ability to adapt to dry climate, so it has become a good ornamental leaf for indoor cultivation in the north and south of our country. It can be placed in a bright living room for a long time, such as when the room is dark, it is appropriate to change it once in 20 days or so.

Its propagation is mainly sowing, small seeds can be sowed with picking, seedlings emerge in half a month, and seedlings can be transplanted with a height of 3 to 5 centimeters. It can also be propagated by cuttings in spring and autumn, cut off the leaves at the top, put them in the sand, place them in the shade, do not get too wet, take root in about 20 days, and turn to normal management when new leaves grow. The rest of the old stem can be replanted with new branches.

Zebra Ye Wanyanqing

Zebra leaf evergreen, also known as Wang Dai powder leaf, dumb sugarcane, is a perennial herb of Araceae, with cylindrical stems, fleshy stems and often white rings on the stems, which are traces of leaf backwardness. The evergreen leaves of zebra leaves are long and oval, with irregular white or goose yellow spots and stripes scattered on both sides of the green main leaf veins, which is particularly graceful and elegant, like zebra stripes, so it is known as zebra evergreen.

Zebra leaf evergreen is native to Colombia and likes warm and humid climate. the optimum temperature for growth is 25 ℃ to 30 ℃. In winter, the indoor temperature should be maintained at about 15 ℃ and the lowest 10 ℃. Potted soil can be mixed with 7 parts of rotten leaf soil and 3 parts of loam soil and 1 part of Gaza. Zebra leaves like semi-shady environment, avoid direct sunlight, and can be cultivated indoors all the year round. Resistant to moisture, a water plate can be placed at the bottom of the basin, in which water is released, so that the water can constantly infiltrate the basin soil from the small holes in the basin floor.

The cultivation technique of Wang evergreen the king likes semi-shade and likes to grow in a hot, humid and well-ventilated environment. It grows well in loose and fertile soil with strong tolerance to drought and shade. The optimum growth temperature is 25-30 ℃.
