Rhododendron in China since the Tang Dynasty is precious flowers and trees

 Is the flower of China's ancient name, one of the Azalea flowers world. China is the main cultivated azaleas countries around the world more than 850 foreign species, there are 460 species in China.

azaleas like sufficient rainfall, climate, cold, humid air, misty, with acidic soil where growth. But there are a lot of shade, drought, poor soil tolerant varieties.

after the loud noise management azaleas?

pruning azaleas are blooming after plastic surgery generally takes stray removed manually, and then make the appropriate thinning, cut through dense branches, her back hair sticks.

fertilizer and water management: water, alkaline northern region, greater hardness, soil alkalization could easily lead to long-term water the flowers, affecting the growth of flowers. Therefore, water in the container before the water should be stored for 24 hours or more, chlorine and other volatile after use. Can also be poured once every 10 days plus ferrous sulfate or eating the right amount of vinegar water. Rhododendron nutrient requirement is not, usually fertilize with water, from late spring to early summer, every half a cake fertilizer applied to thin manure handling facilities, to promote bud germination pumping branches. If there is no cake fertilizer, available on the market to buy some acid fertilizers, use of the same. To 6 months late, a number of quick result can be applied to P and K in order to promote flower bud formation. To late autumn, stop fertilizing, flower bud to avoid the growth of new shoots.

Summer Management: Azalea hi cool, moist climates, summer and autumn should be kept in cool and ventilated place, and to spray foliage and the surrounding water, can also be placed in a shallow dish of water, the flower pot set on the plate, so that slowly take water from the bottom of shallow dish.

flowering regulation: the temperature of the azalea flower bud formation of large flower bud usually start above 15 ℃, suitable temperature is 20 ℃ ~ 27 ℃, the night temperature is kept at 5 ℃. After most of the flower bud formation to be 4 ℃ ~ 7 ℃ for 30 days at low temperature to flower. In addition, shading in favor flower bud formation and flowering.



Chinese rose red rose for a month, four roses and other aliases, is one of the top ten flowers from the enjoy the Is also the world's flowers planted, Italy, Luxembourg, Iraq, Syria and other countries of the flower.

rose like sunshine, warm and moist, fertile soil, air circulation,UGG boots clearanc, good drainage and environment.

rose in the winter pruning your roses for the coming year in order to bud

more tillers, long flowering period, must pay attention to winter pruning.

one, according to Rose pruning

period is very sensitive to temperature characteristics of the main period of winter pruning, rose into the end of dormancy to germination before, from December to next February. Dong Jian's main purpose is to repair the tree, control height, it can actually use the scissors, also known as

Second, the pruning method

1, to promote strong branch development, nurture update branch. Normal development of the rose for every one branch length to the end, the top will bloom if pruned, the branches will lead to a certain period of tender, weak, short, small flowers, flower color is not so good shortcomings. And because there is convergence in the bud sap trend, so that branches in the lower buds have not developed strong. Pruning should be above the base of the flower shoots first and the second 0.5 cm above the bud or branch diameter distance and the same strengths, and the buds cut parallel to the direction of tilt of 45 degrees. Try to keep in mind that the buds outward direction, to reduce the chance of cross branches.

2, renovation of the tree, control height. Thin branches within the crown of laissez-faire, poor flowering, and easy to form ventilation, contributing to the occurrence of pests and diseases, pruning cut the twigs, weak branches, internal and external cross-branches, twigs and branches blind.

rose only in the winter pruning, in order to maintain nutrients in the coming year to grow thick branches, with their bright flowers.



Lagerstroemia Lagerstroemia spend another hundred days of red flowers, amaranth and other aliases. Origin of the Yangtze River in central region, Southeast Asia and Oceania, North and South are now cultivated in China.

crape myrtle tree trunks smooth, the most interesting is people to smile trembled a scratch, it is also known as tickle ticklish trees and flowers. Crape myrtle flowers open from summer to autumn, and some flowering nearly 140 days. Valuable in August from the flower withers, still flowers Thriving, it is Crape myrtle tree is a tree of longevity, some up to several hundred years old.

Lagerstroemia strong adaptability flourished in southern China, regions in the north winter in the open field. It likes warm and humid climate, the ability to heat, are more hardy, drought can, but avoid waterlogging. Lagerstroemia happy light, shaded place in the growth of flowers can not flourish.

Euphorbia poinsettia with Christmas flowers, like the teeth of red, old, alias Johnson, etc., native to Mexico and the Americas and other places.

for poinsettia planted in loose prefer warm, fertile, well-drained sandy loam. Poinsettias are short day plants, such as 8,9 hours of light per day, the temperature at 20 ℃ under 50 days to flowering. Euphorbia fear of drought is also the fear of floods. Propagation is generally carried out 5-6 months with softwood cuttings, rooting around for 30 days. Flower strongly positive in Xiatian Lie Kusakabe growth. A short day habit, the shade 14 hours of short day treatment, about 45-60 days of flowering, not cold, 5 ℃ or so should be put in the greenhouse cultivation. Growth temperature 18-20 ℃. Growing season (especially in summer) to be poured enough water, and pay attention to ventilation, generally applied every 2 weeks 1 fat.

Hemerocallis daylily is a perennial plant, well known in our country. Wild Hemerocallis widely distributed in most parts of northern China, mostly yellow flowers, and edible.

florid Hemerocallis is: hidden love, lotus, treatment and depression.

triploid genetic technology, with the development and application of the birth of the new term. Application of improved genetic technologies native Hemerocallis, Hemerocallis triploid obtained, not just the update term, but to make this traditional flower varieties,UGG shoes, access to new traits, youthful charm.

Triploid Hemerocallis highly personalized power. Variety of color range, with more than 20 varieties. Even re-colored flowers. Hongyun red, pale pink shows off, pink East is Red, yellow gold baby name. Flowers and diverse, there univalve lucky with Double cream volume, there's Samantha petals reflexed. Triploid Hemerocallis

May to September each year, every day new flowers open. It was adapted to a variety of soil, regardless of saline-alkali soil, gravel, barren wasteland, can grow well. Resistance to pests and diseases infection, noise, dust has a strong tolerance. Drought resistant, resistant to half shade, water wet. Cyclamen Cyclamen

with radish Begonia, rabbit ears and flowers alias to the devil in Western countries there are flowers, Our Lady of the Flowers said. Persian origin, into our country and the time is not long. Cyclamen Christmas in Western countries with flowers, or the national flower of San Marino in Europe, cyclamen with

cyclamen cold, not heat, like the warm and humid environment and rich humus, sandy soil with good drainage. The optimum temperature is 15 ~ 20 ℃.

Primulaceae, Cyclamen is a perennial grass. Bulbs (tubers) fleshy, flat ball, red, stalk students drawn from the foliage, solitary, drooping buds, flowers shaped like rabbits; color red, pink, orange, magenta, white and color types; flowering 12 - the following year in May . Rabbit is a famous flower pot flowers. Perennial planting, the annual summer dormancy, should be Fanpen for soil, pots as above, light: positive, should remain sunny, but late spring and summer should cover the resistance, the general temperature: hi warm, but Xiaji Yi cool, hot summer, cultivation difficult, the general should be on the side of the basin to avoid resistance, cool, ventilated place. Optimum growth temperature 16-18 ℃, watering the roots near the soil surface moist for the degree, try to keep foliage dry. Promote flowering of Cultivation: time on the basin; winter proper drying of the soil; control gear less nitrogen fertilizer.

Cyclamen (Cyclamen persicum Mill.) and Mingluobohai often, rabbit ear flower, a Victor, cyclamen is a perennial herb, with a flat round fleshy bulbs. Leaves clustered bulbs to the top, with long-handled, nearly heart-shaped; surface green, with silver white markings. Flowers solitary, axillary; pedicels slender, 15-20 cm high; Huashao drooping reflexed petals outward form functional mitral; are white, pink, magenta, purple and other colors, as well as a tooth side and the type of aroma and varieties. Spherical capsule, containing seeds majority. Flowering from autumn to spring. Origin of southern Europe and Tunisia, and the Near East and other places. Likes the warm and humid climate and fertile, loose, well-drained sandy loam. Avoid hot and humid in summer, dry and likes the cold period of dormancy; for the semi-cold bulb flowers.

Cyclamen flowers grow and bloom in winter, the minimum temperature should be maintained at above 12 ℃ cultivation, greenhouse flowers and plants is an important one, deeply loved. Low temperature in winter in southern China a short time, can be used as rock garden arranged in open field cultivation.

cultivation and management: planting bulbs can breed or division. Seed propagation, the Spring and Autumn can be, but a good month in September. Planting soil requires fertile, loose and drain well: after sowing placed under temperature 18-20 ℃, keep dark, about 4-5 weeks to germinate. If warm water before sowing seed soaking with 30 ℃ for 2-3 hours can promote germination, about half can be unearthed earlier. Pots should be moved to light after germination enough place, and fully watered to keep moist not to dry, when the seedlings birth to 3 true leaves, transplant seedlings Transplanting should be timely; points when planted about 5 cm distance between plants, and pay attention to planting depth. General excavated seedlings soon form a small bulbs planted in soil could not be buried, to expose 2 / 3; to protect the bulbs and prevent aging, charcoal or moss can be placed around the bulb can promote rapid growth. 7-8 leaf seedling growth, the pot can be planted. When planting, bulbs should be 2 / 3 in the earth within; Pentu also require fertile, well drained neutral or slightly alkaline soil, slightly acidic soil (pH value 6.5-7.5), rapid plant growth after transplanting, special attention should be ventilation, Pentu not too wet, but requires high humidity. Segmentation reproduction, usually in the fall after dormancy: the old bulb with a sharp knife cut into two or four, cut when the knife at a pre-selected, so that each flap carries the terminal bud, after cutting the wound in the section coated with ash, and then planted Zhi, over one day before watering to avoid rotting wound. Operation more difficult but split bulbs, and planting on growth and flowering are not as good, so many are not used. Flowers cyclamen seed 5-June after fruit ripening, seed collection should start from green to yellow when the fruit is taken, can not be collected until the time capsule after cracking, due to a crack seed shells off easily. Seeds collected at the tip of the cold storage, typically stored at 2 ℃, can put 4 and a half years old can still germinate well. To make pure seed varieties, flowering varieties should be separated during the period, and the artificial pollination, select the robust parental strains, the strains with different varieties of pollination.

Primulaceae Cyclamen is a perennial flower bulbs, bulbs with oval meat, the old bulbs Zihei brown outside suberin, shortening bulb for the very top of the stem, are the leaves of local, Leaves tufted, heart-shaped oval leaves with white reticulate, margin with teeth. Petiole and pedicel reddish brown. Flowers large, solitary drooping reflexed petals shaped like rabbit ears, also known as rabbit ears flower, colored white, pink, crimson, red, purple and so on. Winter and spring flowering, the best view of 24 months. Capsule 5 crack, dark red.

cyclamen origin Greece, Syria, along the Mediterranean. Likes the sunny and warm, moist environment, avoid hot, for fear water. 10 20 ℃ is the optimum temperature over 30 ℃, easily deciduous dormancy, 5 ℃ the following bulb vulnerable to damage, so the growth in the greenhouse in winter must require loose, fertile, well-drained soil. The cultivation technique is:

a breeding method to seed propagation

mainly divided bulbs can also be used for breeding method. Seed propagation usually in early September to mid-October is appropriate. Planting too early, affecting growth, not on the flowering bulbs; too late, the temperature is too low, affecting germination. Because of its large seeds, soaked with water before sowing is appropriate for germination after 24 hours. Before sowing and planting of the planting pots with soil disinfection. Dip after sowing pots, placed in 18 20 ℃ shade to germinate. Usually two weeks to take root, 46 weeks can give birth to a cotyledon.

Second, the cultivation and management

usually 23 hours of seedling leaves, 56 leaves were transplanted change a basin, basin set in September. With full root when transplanting, do not shake off the original soil, soil depth to bulbous pots of 1 / 3 1 / 2 exposed soil outside the better. Pouring water after transplanting apply and pay attention to shading. Cyclamen seedling growth is slow growth next year 36 month peak. Fertilizer and water management should be strengthened in this period, the monthly liquid fertilizer applied twice. Irrigated dry surface soil, but watering and fertilization are not poured into the top of the leaves and bulbs to prevent rot. Growing season temperature was around 18 ℃ for good, too high will lead to a small bulb dormancy, flower hamper the year. After the temperature dropped in October into the indoor, sunny setting at room temperature to maintain 10 18 ℃, and pay attention to hold basin moist, but avoid too much humidity, not fertilizer flowering period to prevent the impact of flower life.

Third, security aestivation

cyclamen hi cool, moist climate, the temperature above 30 ℃ higher than that goes into dormancy. Summer, hot weather, such as poor ventilation, bulbs perishable. So one year seedling shade of cyclamen should be placed where ventilation and shelter from the rain, and its regular spraying, watering, shading, cooling, creating a cool environment to promote their growth. More than two year old on the ball, it should be on the north terrace in summer, window sill or a shade under the eaves, hold basin moist and ventilation. This Huanpen re Zaihou, you can quickly send budding leaves, early flowering, more flowers.

conservation

dormant cyclamen, flower, also known as rabbit ears, radish Begonia so strange flower. Anti-up roll when the flower is blooming, mosaic and tours, color rich and varied, from the winter solstice and summer flowering,Discount UGG boots, very popular. Mediterranean origin of the cyclamen, hot summer conditions in a dormant state, thus requiring a moderate growth environment clean, avoid heat, the fear of floods, hi sparse Songsha loam. Regardless of family self-support or professional production, conservation must pay attention to the summer and autumn, the two key aspects of training, or after flowering, is prone to bad ball, miss the best growth period, the flowers are not brilliant or unstable phenomena such as flowering. For cyclamen safe through the summer and autumn, should take the following measures:

1. Fertilizer and light before summer temperature control. Into late May, temperatures up to 28 ℃ below the light gradually increased, especially in the greenhouse light and temperature elevations occurred earlier. Cyclamen in this condition, will appear under the leaves yellow, heart leaf wrinkled, drooping petioles atrophy, but this is not caused by lack of water or Quefei, so do not flood pouring concentrated fertilizer applied, otherwise, easily broken ball. Late in May in time to ventilation, shade measures to reduce light and temperature,cheap UGG boots, reduce watering, hold basin semi-dry, and gradually reduce the temperature and humidity. Mass production can shed additional shade net, if the family self-support, put the pots moved to the shade, so cyclamen into summer hibernation. However, when students should be allowed to grow normally and the ball, can not sleep.

2. Dormancy maintenance. In mid-June to mid-August is the cyclamen aestivation period, environmental conditions should be kept cool and ventilated, do not put the ball from out of focus, can be in the original basin. Dormant period in mid-June should be sprayed to the surface of a basin of the Bordeaux solution or Carbendazim 500 times, the soil should remain moist on the part of the state, every 3 days to spray a water basin surface, should also be insect, rodent and human Squeeze the ball shoots, daily take low-light treatment. No fertilizer was applied to regularly check whether the shrinkage or corm pests and diseases, identify problems and take timely measures.

3. Fall maintenance management. Into late August, the temperature decreased, the base at the top of the ball cyclamen buds began to sprout, leaf bud color, elongation, this time should be taken to change a basin, fertilization, watering, see the light of other measures. Huanpen generally do not increase the size of pots, but the ball can increase the One, the general bulbs in about 3 cm to 16 cm pots. Cultured with 3 copies of soil humus, l copies of organic manure, 1 part sand, loose and fertile soil to cultivate a good permeability. Soil replacement, the original soil removal, not to hurt the fibrous roots, removal of dead leaves, put pots in the center of the bulbs, corms buried people at a depth of 1 / 2 to 1 / 3 as well, all buried bulbs or floating on top is not good . After the seedlings are irrigated properly, fill the bulb 1 / 2 to 1 / 3 of the exposed soil surface, the first release shade 5 to 7 days, and then gradually see the light of humidification.

other cotyledons grow up to 1 cm can be applied when the foliage or pouring liquid fertilizer, foliar fertilizer with urea and ammonium dihydrogen phosphate 0.1% of all alternating spraying, can also be buried in water, but not poured into the bulb above, there are flower buds appear in late October, the use of liquid fertilizer is best. 2 cm around the bulbs into the phosphate hinge exogenous, the effect is also very good, and beneficial flower bud formation and growth.

before flowering is also important to keep the time. Leaf length is not good, not good flower opening. But too much nitrogen in November also prone to excessive growth phenomenon. Only leaves, not flowers or leaves to spend less time to adjust to this phenomenon of water, fertilizer, light of three factors: First, see the see the wet dry to leaf water and ground water based; Second, adequate P and K applied, the appropriate N fertilizer; third is full see the light; Fourth, in addition to the center of leggy leaf, small leaf, excess leaves, they can pull the leaves out so central to light bulbs, to facilitate the rapid formation of flower buds, ensure flowering concentrated.

4. Pest and disease control. Cyclamen is not serious pests, as long as the period of dormancy handle, generally no major pests and diseases. Soil disinfection should be prepared to eliminate infected bulbs contaminated the soil, usually with potting soil should be one week in the sun, or the mix of people killing bactericidal agents. Growing season leaf diseases occurred, can be regularly sprayed with carbendazim, on behalf of the Forest of zinc to control. For the red spider, and physical methods can be used in addition to killing the Pharmacy, the Pharmacy using acaricides, dichlorvos spray mixed with omethoate (1000 times), the effect is also very good, or 500 times with a cotton ball dipped in detergent water or cigarette butts 800 times with good results.
