Poin_set_tia Scientific name: euphorbia pulcherrima willd English name: poin_set_tia Families and genera: Euphorbia Euphorbiaceae Also known as ivory red, old Johnson, Christmas flower, the poin_set_tia. Native to Mexico Tasman Branch (taxco) region, long before being introduced into Europe, it was by the local Aztecs (aztecs, American Indians a) used as a pigment and drugs. 1825, first by the U.S. Ambassador in Mexico • Joel Poin_set_t (joelrobertspoin_set_t) into the United States. • Buell Robert Frost (robertbuist) to _set_ the scientific name of this plant is now using the "euphorbia pulcherrima willd". Meanwhile, the family name evolved from the Poin_set_t's "poin_set_tia" were used as the poin_set_tia, in English, still in use. Evergreen shrub, 50 to 300 cm high, stems and leaves with white milk. Stems smooth, green twigs, old branches dark brown. Alternate, simple leaves, ovate oblong, entire or wavy lobed, sometimes showed a violin-shaped, narrow at the top of blade, lanceolate; leaves are hairy, leaf quality thin veins obvious; the top of the leaves near the inflorescence was bract-like, flowering plants in red, as the main viewing area. Inflorescence cymose cup arrangement, the top students; involucre pale green, toothed edges and 1 to 2 large yellow glands; male with a handle, without perianth; female flower solitary, located in the center of involucre; natural flowering December to next February. White and pink cultivars. Prefer warm, moist and sufficient light. Cold intolerance, as a typical short-day plant. Direct glare and insufficient light were against their growth. Avoid water, moisture can hold basin. Flowering short day treatment in advance. Euphorbia hi humid and sunny environments, phototropism strong, strict requirements on the soil, but slightly acidic type of fertile, moist, well drained sandy loam is best. Weak resistance to cold, east, north China greenhouse cultivation, must be moved into the greenhouse before frost, or low temperature, easy to yellow leaves, fallen leaves. Winter temperature not lower than 5 ℃, to 16-18 ℃ appropriate. Demanding on the water, the soil is too wet, easily lead to root rot, fallen leaves, poin_set_tia leaves easily, the temperature is too high, the soil had done too wet or too weak light will cause leaves. Poin_set_tia bright colors, long flowering period, a time when Christmas, New Year, Chinese New Year flowers, potted plants decorated the indoor environment can increase the festive atmosphere, very loved by the people. Arrangement of the meeting is also suitable for other public places. Southern Warm to open field cultivation, landscaping the garden, but also for cut flowers. Poin_set_tia breeding: Poin_set_tia by cutting the main breeding. The old branches, twigs can be cutting, but the branches is difficult to survive through tender. Generally more robust in the choice between 2-3 months a year old branches, 8-12 cm long cut to make cuttings. In order to avoid the milk out, immersed in water immediately after cutting or dipping ash, to be _insert_ed immediately after cutting a little dry with good drainage of the soil or coarse sand, the soil surface leaving 2-3 buds, moist and slightly shaded. Temperature at 18-25 ℃ about 2-3 weeks to take root, and then by about two weeks can be planted or transplanted on the basin. Seedlings after the basin to give sufficient water, placed in half shade about a week, and then moved to see the sun To the place sooner or later exercise of about half a month, and then into the sunny place conservation. Poin_set_tia cultivation: Poin_set_tia plants grow faster, be plastic trim line. Generally stay in the base of the section 3-5, the rest cut in order to promote its pumping hair branching; to be 15 cm long branches may also be trimmed once again. Before and after the end of the trim to the beginning of autumn, and then can be plastic, get bent shape. Take the branches to bend generally begins around 18 cm, two days before each bend, do not get water, making it slightly wilting branches, so easily broken. Operating time from 10 am to 4 pm, because this time the branches soft and easy to bend. Take the bend, branches with twine to pull into a bow, and to be fixed. Can bend in different directions from time to time to take time to tie the branches twisted spiral circling around, so plants grow shorter. The last turn should take about 20 days before flowering. Strong shape bending to get the attention should be placed around the branches, weak branches should be placed in the middle, high degree of bending down the branches to be bigger, but to prevent broken branches, so as to avoid "dead bend." Plants can take shape by bending branches evenly distributed, the same height, flowering and tidy, the individual plant plump appearance. In addition, with the growth of CCC b9, ccc for foliar treatment or soil water, can also shorten section, the dwarf plant type purposes. Poin_set_tia is a short day plants, the natural flowering period of 12 months. To make it available early flowering short day treatment. Generally maintain the sunshine nine hours a day, ill with stuttering 45-55 days to flowering varieties of shade. To bloom in the National Day, to be started in early August time shading, treatment should be increased on fertilization, particularly P, in order to spend a large Shigeru. Poin_set_tia bracts colorful, long flowering period, usually up to 3-4 months, and flowering time when Christmas, New Year, so it can not only grow in the gardens cultivated, the most suitable for pot cultivation, as a balcony, living room, conference room green decoration materials, etc.. Poin_set_tia pests: Poin_set_tias in greenhouse cultivation process susceptible to gray mold, root rot, stem rot, leaf spot and other pests, at home and abroad, many targeted research. Root rot and stem rot can infect adult, also at the seedbed of infection, resulting in serious losses. Occurrence of the hot season generally more severe in the cultivation of the soil moisture content is high also easily occur. The phenomenon of the early wilting plants appear, at this time if the view of its stem base, showing that the phenomenon of constriction was light brown, but no diseased plants infected with corruption, the phenomenon of hydrolysis, after the lesion gradually spread upward, the phenomenon is also increasingly severe wilting, stem slight depression in brown lesion, post-lesion Ministry of collapse, causing serious and withered plants died due to lack of water, and sometimes whole plant was soaked yellow and finally died decay, partially visible near the surface of white mycelium, expandable to serious soil cultivation. The roots of illness, often resulting in the phenomenon of root rot, the initial impact of the normal growth of plants, leading to death in severe cases. Main pathogen Phytophthora (phytophthora), Rhizoctonia solani (rhizoctonia), Pythium (pythium) and so on. Rooting cuttings in the basin, the most susceptible to Rhizoctonia solani damage, especially when the stems were injured or fertilizer! Salt accumulation in the medium when the surface; rot fungi in the poin_set_tia when adult, and its possible cutting already when the invasion, when the environment suitable for breeding, the show deterioration, resulting in root rot and death; high temperature and excessive irrigation (stress conditions) can lead to Phytophthora damage. Occurred mainly in spring and summer leaf spot is more serious, and multi-lesion from the old leaves start to occur. The early leaves have purple to brown spots on the lesion for nearly circular to irregular in shape, after the lesion gradually expanded, most lesions heal each other to form a large lesion, the latter slowly to gray-brown central lesion. Lesion tissue showed severe necrosis-like, resulting in distorted leaves, dry. Pathogens were cercospora.puleherrimaetherp., By rain, wind dissemination, or wound penetrated by the leaf margin. 4.3 Pest Also known as red spider mite is a common greenhouse pests. Occur throughout the year, more than 20 generations, at a temperature higher drought severe cases, 3 to 6 months and 9 to 11 month peak occurred. If mites are mites or habitat in the old leaves of the dorsal Hi, leaves victims with yellow spots, check dorsal can be found parasite, eggs, screen, and secretions and other debris. Damage occurring on a large webs, resulting in stagnation of plant growth, dry leaves, fall, plant death. Thrips body length is only about 1 ~ 2mm, almost all leaves of greenhouse-cultivated plants, or take the harm found. However, under normal circumstances the damage to the poin_set_tia is not very serious. Into the nymph light yellow or orange, to file against suction mouth parts plants. Damage sites, including buds, leaves, flowers, etc., particularly in young leaves and shoots the worst affected, resulting in stunted plants, leaf main vein on both sides by the white stripes, can be identified as thrips damage characteristics. Victim leaves, white or brown stripes, a serious deformities caused by leaf distortion. Flowers suffer deformation. Thrips adults on yellow sticky paper effective, but the blue and white paper better armyworm. The birth of August 31 oath poin_set_tia flowers (euphorbia pulcherrima)

Biological properties
Hi warm, humid and sunny environments. Optimum temperature for the growth of poin_set_tia 18 ~ 25 ℃, 4 ~ 9 month 18 ~ 24 ℃, 9 months to April the following year for the 13 ~ 16 ℃. Winter temperature not lower than 10 ℃, otherwise it will cause the pan-blue bracts, the base of yellow leaves fall off easily, the formation of "de feet" phenomenon. When temperatures rise in spring when the bud from the stems can continue to branch out. Euphorbia most sensitive to water, adequate water supply as long as the growing season, leaf growth is rapid, sometimes elongation, leaf narrow leggy phenomenon. On the contrary, the lack of water or basin earth dry when wet, will cause yellow leaves fall off. Therefore, control of water is directly related to growth and development of poin_set_tia. Poin_set_tia is a short day plant. Stem and leaf growth period in the sun to be sufficient to promote rapid luxuriant leaf growth. Red bracts in advance to make the daily light control within 12 hours to promote flower bud. 9 hours a day, such as light, 5 weeks after the bracts to turn red. Fertile soil in loose, sandy loam and good drainage is good. Pot with potting soil, leaf mold and sand mixed soil better.

Daily Maintenance
Poin_set_tia, also known as Christmas flowers, old Johnson, are native to Central Africa, a color-type foliage plants. The small flowers are not easy to be noticed, cause for concern is the leaves at the top of the plant, after the winter the leaves will become bright red, bright extraordinary. Flowering from December to next year's February sustainable, flowering at a time when Christmas, New Year, Spring Festival, is ideal for a festive atmosphere. Poin_set_tias like warm moist air environment, temperature intolerance, excessive sun exposure are the same with the poor lighting is not conducive to growth, fertilizer and water management to do well during the growing season, topping _set_ top conservation. Should be taken to avoid over watering done when wet, otherwise it will cause plant yellowing leaves off the bottom, shoot growth is uneven, hot summer weather should be appropriate to increase the amount of water, but not to the basin water, in order to avoid root decay. Pentu to see other seasons of wet and dry specific circumstances. Euphorbia strict requirements of the soil generally fertile sandy soil on the line. Huanpen should be timely to join decomposition of organic fertilizer as basal fertilizer, grow and blossom in the season, a liquid fertilizer applied every two weeks or so. When autumn comes, can be applied on a number of phosphorus fertilizer rich in potassium to promote flower bud, bud Ye Yanhong ensure pure. Poin_set_tia into the growth period, growing faster, then we must pay attention topping the first _set_, or shoot growth is too high, in addition to easy to fall in addition to affecting the appearance of the shape, reducing the ornamental value. Poin_set_tia cutting propagation method can be taken in the spring and summer period when the scissor branches, some of the ash spread in the notches to prevent the incision decay, into the soil around the about twenty-five days to take root. In addition, the poin_set_tia poisonous sap, topping, cutting the time not to contact, in order to avoid skin irritation.

Cultivation steps
Poin_set_tia, Euphorbia upright deciduous shrub. Alternate, simple leaves, ovate to broadly elliptic lanceolate, 10-15 cm long, the back of soft hair, was born in the narrower leaves the top branches (also called bracts). Euphorbia native to Central America, both as a potted plant in northern China. Flowering December to next February. First, the propagation method Poin_set_tia bowl or sink usually mud cuttings, twigs and branches can use sleep. Cutting should be carried out in early spring after flowering, cut down use of dormant branch, each cut into 10 cm for the cuttings. Cut 2 to 3 days after the dry or coated with soot to be notches notches at the fully dry milk, cutting the prime sandy soil, the depth of cutting one-third of the length, spacing of about 5 cm, after sowing irrigated placed ventilation half shade, the temperature for 15 至 20 ℃, Pentu maintained see dry see wet as well. New roots to students about a month, when the new shoots grow to 10 cm can be planted in small pots. Second, the culture soil preparation Poin_set_tia hi loose, well drained soil, usually with 3 copies of garden soil, humus 3 copies, 3 copies of leaf mold, the maturity of the cake 1, plus a small amount of slag mix. Third, the temperature Poin_set_tia Joy warm cold fear. 9 months late each year into the room, to enhance ventilation, the plant gradually adapt to the indoor environment, the winter should be kept at room temperature 15 ℃ to 20 ℃. At a time when bract color and flower bud differentiation stage, if the room temperature below 15 ℃ below the flower, leaf development bad. After 12 into the mid-flowering stage, to gradually ventilation. Fourth, light Euphorbia hi adequate light, strong phototropism, is a short day plant. Throughout the year should be plenty of light, color and flower bud bracts, flowering period is even more important. Such as insufficient light, easy to leggy branches, disease susceptibility, color dark, dark place long-term placement, not flowering, winter deciduous. In order to advance or delay flowering, can control the light, generally give 8-9 hours per day of light, will bloom for 40 days. V. Fertilization Poin_set_tia Joy fertile sandy soil. In addition to the pots, change a basin, adding organic fertilizer as basal fertilizer and water chestnut slices, but during the growing season, flowering, applied every 10 to 15 days a diluted 5 times the full maturity of sesame residue liquid fertilizer. When autumn comes, can also be combined with 0.3% of fertilizer applied once a week, for 3 to 4 times, to promote the bract color and flower buds. VI watering Poin_set_tia intolerant of drought, but also intolerant of wet, so water should be under the weather, Pentu flexibility and plant growth, generally moist without watering to keep the basin ground water for the degree, but after flowering to reduce watering. VII Pruning Before and after the Ching Ming Festival will sleep old strain Huanpen, cut off the roots and branches, the sick, and promote the germination of new technology, to be topping the growth process twice, first in late June, the second in mid-August. Cultivation should be controlled in the large mast of water, especially before molding plant in autumn. To be branches 20-30 cm long plastic for bending begins, the purpose is to make the plant type short and neat flower head, evenly distributed and improve the watch.

Poin_set_tia plants grow faster, be plastic trim line. Generally stay in the base of the section 3-5, the rest cut in order to promote its pumping hair branching; to be 15 cm long branches may also be trimmed once again. Before and after the end of the trim to the beginning of autumn, and then can be plastic, get bent shape. Take the branches to bend generally begins around 18 cm, two days before each bend, do not get water, making it slightly wilting branches, so easily broken. Operating time from 10 am to 4 pm, because this time the branches soft and easy to bend. Take the bend, branches with twine to pull into a bow, and to be fixed. Can bend in different directions from time to time to take time to tie the branches twisted spiral circling around, so plants grow shorter. The last turn should take about 20 days before flowering. Strong shape bending to get the attention should be placed around the branches, weak branches should be placed in the middle, high degree of bending down the branches to be bigger, but to prevent broken branches, so as to avoid "dead bend."

Damage sites, including buds, leaves, flowers, etc., particularly in young leaves and shoots the worst affected, resulting in stunted plants, leaf main vein on both sides by the white stripes, can be identified as thrips damage characteristics. Victim leaves, white or brown stripes, a serious deformities caused by leaf distortion. Flowers suffer deformation. Thrips adults on yellow sticky paper effective, but the blue and white paper better armyworm. Control of whitefly is the key to avoiding the generation of a large number of ethnic groups. Whitefly adults will be attracted to bright yellow, so the yellow sticky trap insects on the paper is useful in the detection. There are many whitefly control over medicines, such as "buprofezin", "efficient big hero," and so on, you can try. It should be noted here that in a large area using a new drug test before the injury have to do first, confirmed that the dose does not produce injury to the plants before large-scale use.

Debate about the toxicity
Some people think that the whole plant poin_set_tia poisonous white sap in the stems and leaves can irritate the skin, may cause skin irritation, allergic reaction, if the leaf eating, vomiting, abdominal pain, poisoning or even death. There is no scientific evidence that toxic rumors. As early as 1971, Ohio State University on poin_set_tia toxicity problems have done case studies. Found that rats consumed large doses of poin_set_tia leaves, the rats in the diet and daily routine without any exception, but no deaths, poisoning and other symptoms. American Toxicology Bulletin (POISINDEX) provided a study of toxic substances information center results, the conclusion is: A child weighing 50 kg intake of 500-600 pieces poin_set_tia leaves poisoning does not occur. In 1990 Kruger (Klug) conducted a telephone interview, the results show that very few people on the white sap of the poin_set_tia is not a skin reaction, interviewed 353 people who have skin redness 0.02%, 0.0028% of the people flow nose symptoms. Furthermore, according to the American Medical Association found no intake of Euphorbia harm after the death or serious cases. In short, the facts have proven that the poin_set_tia is not as toxic as some media have said, Moreover, as with other flowers, the poin_set_tia is for people to watch and not for human consumption! So when the purchase or maintenance poin_set_tia, you can completely eliminate the concerns, brought the poin_set_tia to enjoy the festive and fun.

Optional Points
1. Number of flower head: every single branch is called a flower head, flower heads usually less than 6 months and so for the next flower, 6-8 flower heads for the middle flower, flower head more than 8 for Excellence in flower. 2. Flower heads flush: the ideal poin_set_tia flower head should be the same size, uniformly distributed in a sphere, surrounded with Mimizaza, crown height ratio greater than 1.0, preferably greater than 1.3. Finished flower looks like generous stretch. 3. See foot leaves: the poin_set_tia holding up its feet from the side leaves, if a lot of yellow leaves fall off, is a low-quality flower. Determine whether the thick branches also an important criterion for quality poin_set_tia. Leggy branches, nodes on him as long pull, a look from the side branches fully exposed, is also defective. 4. A flower: Poin_set_tia is very beautiful, but you is not pleasant to spend it, but its bracts. But the view at the top of the real flowers, will help determine the quality of poin_set_tia. If the top has small yellow flowers most of the open flowers on the lateral bud will be more, which is "opened," so the poin_set_tia flowering mostly short, buy a home is very difficult to extend the display time. 5. Hands: gently fiddles Corolla, if limp, long flowering period can not. Poin_set_tia leaves the ideal should be relatively strong, to give people the feeling vigorous.
