How to raise Saxifraga and how to treat powdery mildew

Saxifraga is very good-looking and clever. Saxifraga can be planted not only in the soil, but also in the water. How to raise Saxifraga? If there is powdery mildew in the process of breeding, how to treat it?

How to raise Saxifraga?

1. Suitable temperature

It likes warmth, generally more than 15 degrees above the most comfortable, winter above 0 degrees can safely survive the winter, summer temperature should not exceed 30, summer must be put in a cool place, raise outside very easy sunburn!

2. Appropriate light

Just give it bright light properly, there is no need to bask in the sun! If you think it's too dark, you can give a little scattered light sooner or later, not in direct sunlight, let alone exposure!

3. Proper watering

It likes the warm and humid environment, naturally can not grow in dry places, to often water around, increase air humidity, but also shows that it is very suitable for growing in glass bottles! Especially in winter it can't be too dry.

4. Suitable soil

It likes humus soil, of course, it should be loose and drained well, and the rotten leaf soil can add a little river sand! Can add a little liquid fertilizer to the soil every month, a small amount, do not pour on the leaves!

The propagation method of Saxifraga:

In fact, reproduction is cutting and ramet, cutting is the most appropriate, generally cut a strong branch in early summer, a little wait for the wound to heal! Just soak in water and wait for it to take root, and then transplant it! Ramet is easier. If you see a strong branch growing seedlings next to it, you can pull it up and replant it.

Pest control of Saxifraga

It is usually muggy or dry to get sick! For example, Botrytis cinerea, leaf solution moldy, humidity is too large will be like this, stagnant water is also, spray with gray mold gram on the line!

Powdery mildew can be sprayed with carbendazim. Insect pests may be whitefly and whitefly. Spray them with Huanshen in time when you find them.

The breeding method of Saxifraga is introduced here. Let's take a look at whether this breeding method is right or not.

Culture methods of Saxifraga

Selection of potted soil of Saxifraga

The best soil selected by potted Saxifraga is sandy soil rich in organic matter, and it also has good drainage, which can be made by mixing self-made culture soil with river sand.

Temperature and light

Temperature: Saxifraga likes warm environment, and the most suitable growth temperature is between 15 ℃ and 25 ℃. Saxifraga is also hardy and can spend the winter at a low temperature of 5 ℃.

However, Saxifraga tricolor is not cold-resistant, and the overwintering temperature is 15 ℃. If it is lower than this temperature, it will die, so it is necessary to keep warm in winter.

Light: if the light is not enough, the color of the leaves will become dim. Indoor shade is also needed in summer to avoid direct light. The room temperature is kept above 5 ℃ in winter. Place in a sunny place near the south window of the room.

Water and fertilizer management

Watering: during the growth of Saxifraga, a large amount of water should be watered to make the pot soil fully moist, but the flowerpot should not be immersed in water. The amount of water should be reduced gradually during the two weeks after flowering. When the plant enters the dormant state, as long as the pot soil is not dry.

Watering during the growth period, the basin soil should be kept moist, it is easy to wither and fall the leaves due to drought, and at the same time, it is also necessary to prevent stagnant water in the basin, otherwise the roots are easy to rot.

Fertilization: fertilizer should be applied under the leaves of Saxifraga so as not to stain the leaves and affect the plant growth. During the peak growth period in spring, nitrogen fertilizer was applied every 20 days, and no fertilizer was applied at high temperature in summer and low temperature in winter.

Reproduction method

Saxifraga can be propagated by sowing and ramet. Sowing is carried out from March to April, and ramet can be carried out in all four seasons, but it is the best in spring and autumn.

Matters needing attention in domestic cultivation of Saxifraga

Change the basin

Saxifraga prefers loose and breathable soil, which tends to dim the color of the leaves. Therefore, Saxifraga should be changed every other year, in early spring.

Diseases and insect pests

The main diseases of Saxifraga are gray mold and powdery mildew.

Saxifraga pests may have whitefly and whitefly.

In daily maintenance, we should always pay attention to observation, remain vigilant, and raise beautiful Saxifraga, just like protecting beautiful love.

Saxifraga Saxifraga stolonifera Curt. Saxifraga how to raise Saxifraga / Saxifraga how to breed Saxifraga Saxifraga stolonifera Curt. Introduction of Saxifraga (scientific name: Saxifraga stolonifera Curt.) belongs to Saxifragaceae. Born in forests, thickets, meadows and shady rock crevices at 400 m above sea level. Its origin is China, and it is also distributed in Korea and Japan. It is a trailing plant with waterfall-like creeping branches that can be widely cultivated as an ornamental plant. Contains alkaloids, potassium nitrate, potassium chloride, arbutin (arbutin). The phenolase contained in its chloroplast can put cis-caffeic acid and whole herb into medicine; slightly bitter, pungent, cold, small poison; dispelling wind and clearing heat, cooling blood and detoxification. Morphological characteristics of Saxifraga Saxifraga is a small perennial herb that does not wither in winter. Roots slender; stolons slender, purplish red, sometimes bearing leaves and adventitious roots. Leaves basal, usually several; petiole 3-10cm long; leaf blade fleshy, orbicular or reniform, 4-6cm in diam., sometimes larger, base cordate or truncate, margin shallowly lobed and irregularly serrulate, green above, often with white markings, purplish red below, pilose on both surfaces. Flowering stems up to 25cm, erect or slightly oblique, branched; panicles, rachis and branches, pedicels glandular hairy and tomentose; bracts lanceolate, pilose; sepals ovate, apex pointed, extending outward; flowers numerous, petals 5, white or pink below 2 extra long, elliptic-lanceolate, 1-1.5cm long, 2-3mm wide, upper 3 smaller, ovate, with yellow spots at base. Stamens 10, filaments clavate, about 1 time longer than sepals, anthers purplish red; ovary globose, style slender, stigma slender. Capsule ovoid, apex 2-parted, beak-shaped. The flowering period is from May to August and the fruiting period is from July to November. The ecological habits of Saxifraga there are many forms of Saxifraga plants, of which one year and many years are parasitic plants. Most flowers have five petals, and the distinction between petals and receptacles is very clear. They are usually exposed and often grow together. Herbs, shrubs, small trees or vines. Leaves alternate or opposite, usually without stipules. Flowers bisexual, sometimes unisexual, marginal flowers sometimes sterile; inflorescences diverse; tepals usually 4-5 base, sparse 6-10 base, imbricate, valvate or rotated; sepals sometimes petaloid; petals usually free, or absent; all hairs. Leaves simple, base tufted, petiole long, densely villous; orbicular to cloudy-reniform, fleshy, 4-9cm wide, margin lobed, sparsely acutely dentate; purple-red below, glabrous, densely globose. Flowers white, upper 3 petals smaller, ovate, somewhat, lower 2 petals larger, lanceolate, drooping, shaped like tiger ears. Capsule ovoid. The breath is slight, the taste is slightly bitter. Stamens (4 ~) 5-10, or numerous; sometimes staminodes or glands present; carpels 2-5 (- 10), nearly free or somewhat connate, ovary superior, semi-inferior to inferior. Capsule, follicle or drupe. Undergraduate, in woody plants, usually with a ladder-shaped perforation plate, often with a single perforation plate. Cultivation techniques of Saxifraga 1. Climatic soil: like cool and moist, the soil is required to be fertile and moist, and it is better under the dense and moist forest and on the cool and moist wall. 2. Planting: propagate with separate plants. In summer, Sichuan selected the plants with developed fibrous roots and strong growth, with a height of 7-10cm, and the seedlings grown from stolons were pulled up as seedlings. If it is cultivated under the forest, it is necessary to remove ground weeds and overdense shrubs, open holes according to the row and plant distance, plant shallow on the surface, and press the fibrous root in the soil. If cultivated on wet stone ridges or stone walls, the seedlings can be planted in stone crevices, and the whisker roots are pressed and watered with wet humus soil. 3. Field management: weeding frequently and pulling out excessive bryophytes. The main diseases of Saxifraga are Botrytis cinerea and powdery mildew. Botrytis cinerea is mainly harmful to leaves. Spots often occur along the leaf margin, semicircular or round to irregular, water-routed, dark green to brown. When the humidity is high, the disease part expands rapidly and the whole leaf becomes dark brown and rotten, and the disease part produces a gray mildew layer. The 800-fold solution of 28% Botrytis cinerea wettable powder can be used, and 50% carbendazim 800-fold solution can be used to control powdery mildew. Pests may include whitefly and whitefly. [2] maintenance points 1. Temperature. The suitable temperature for growth is 18-21 ℃ from March to October and 13-15 ℃ from October to March. The room temperature should not be lower than 0 ℃ in winter and 30 ℃ in summer. Light. Indoor shade is also needed in summer to avoid direct light. 3. Moisture. During the growth period, the basin soil should be wet rather than dry, in addition to watering, but also need to often spray water to the air and the ground. Maintain high air humidity. High temperature in summer, to control moisture, should be a little dry should not be too wet. It is appropriate to increase the humidity of basin soil and air after autumn. 4. Soil. The rotten leaf soil with loose, fertile and good drainage should be selected. 5. Fertilizer. During the growth period, rarefied mature liquid fertilizer was applied every half a month. Do not stain the foliar surface with fat. Species classification of Saxifraga Saxifraga in the past Saxifragaceae was classified as Rosaceae. According to the results of new phylogenetic studies, Saxifraga forms an independent order. Saxifraga has many forms, including annual and perennial herbs, as well as shrubs and trees. Some species are succulent plants and two species are parasitic plants. And some aquatic plants. Most of the order Saxifraga showed dicotyledonous characteristics. Leaves generally cross on both sides of the stem. There are usually stipules. Most flowers have five petals, and the distinction between petals and receptacles is very clear. Carpels are generally exposed and often grow together. One family of Saxifragaceae dicotyledons of the subclass Rosaceae. Herbs, shrubs, small trees or vines. Leaves alternate or opposite, usually without stipules. Flowers bisexual, sometimes unisexual, marginal flowers sometimes sterile; inflorescences diverse; tepals usually 4-5, sparse 6-10, imbricate, valvate or rotated; sepals sometimes petaloid; petals usually free, or absent; stamens (4 ~) 5-10, or numerous; staminodes or glands sometimes present; carpels 2-5 (- 10), nearly free or ±connate, ovary superior, semi-inferior to inferior. Capsule, berry, follicle or drupe. The vessel of the family is usually with a ladder-shaped perforation plate in woody plants and a single perforation plate in herbaceous plants. The chromosome is xylene 6, 18, and 21. The receptacle of the family plant, or the top of the ovary of the superior flower, or the staminodes facing the surface of the ovary, usually secrete honey, lure insects and help with pollination. About 80 genera, more than 1200 species, widely distributed, several times all over the world, mainly producing temperate zone. There are 28 genera and about 500 species in China, which are distributed in the north and south, mainly in the southwest, among which the genus Artemisia is endemic to China (see photo). Most of the undergraduates are medicinal or ornamental plants, such as Rabdosia, Rabdosia, Hydrangea, Ghost lantern, Saxifraga and so on. Changshan can treat malaria. The stem of Saxifraga tenuifolia is often metamorphosed into a creeping branch (runner), which is often mixed as a stolon, which is different from the latter in that the slender branch is often slender, which occurs from the leaf axil of the leaf cluster, and its tip gives rise to adventitious roots on the node, growing leaves and buds upward, forming a lotus-like leaf cluster. When it lives independently, the internodes of the stoloniferous branches often die. The dietotherapy or medicinal value of Saxifraga the medical information and health dietotherapy information of Saxifraga are only for reference 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. Attribute of traditional Chinese medicine 1. "Compendium of Materia Medica": Tiger ears, shady and wet places, people are also planted on the stone mountain. The stem is five or six inches tall and has fine hairs. A stem and a leaf, such as the lotus leaf cover shape, people call it the lotus leaf, the leaf is as big as money, like the newborn sunflower leaf and the ear shape of the tiger. Summer blossoms are light red. 2. Saxifraga chinensis SaxifragafortuneiHook.F. Nearly this species, but without stolons, petals dentate; distributed in Sichuan and Hubei.

The chemical composition of Saxifraga chinensis contains bergenin (bergenin), quercetin (quercitrin), quercetin (querctin), Gallic acid (gallicacid), protocatechuic acid (protocatechuicacid), succinic acid (succinicacid) and methyl fumaric acid (mesaconicacid). The stem contains catechol (catechol). The root contains volatile oil. In addition, arbutin (arbutin), chlorogenic acid (chlorogenicacid), quercetin-5-O- β-D-glucoside, norbergenin, amino acid, potassium nitrate and potassium chloride were isolated from Saxifraga. The phenolase in its chloroplast can oxidize cis-caffeic acid (cis-caffeicacid) to the corresponding orthoquinone, which is naturally oxidized to produce chestnut tretin (esculetin). Pharmacological action 1. Cardiotonic effect on isolated frog heart dripping with fresh juice filtrate pressed by Saxifraga or 1:1 ethanol extract 0.01ml showed a certain cardiotonic effect. After decalcification, the extract still had an exciting effect on the heart, but it was weaker than that before decalcification. The cardiotonic effect of this product to calcium chloride occurs slowly and lasts for a long time. 2. Diuretic effect intravenous injection of Saxifraga ethanol extract 1ml/kg in anesthetized dogs and conscious rabbits showed obvious diuretic effect. After destroying the glycosides contained in the extract, it still has a certain diuretic effect. 3. Other effects of Saxifraga fresh juice on staphylococci and streptococci in vitro test showed no bacteriostatic effect. 4. After intragastric administration of 35ml/kg fresh juice of toxic rabbits, no adverse reaction was found 24 hours later, and no adverse reaction was found after repeated administration of 60ml/kg on the second day and observed for 3 days. Character identification of all hairs. Leaves simple, base tufted, petiole long, densely villous; leaf blade orbicular to cloudy-reniform, fleshy, 4-9cm wide, margin lobed, sparsely acutely toothed; purple-red below, glabrous, densely globose. The flowers are white, the upper 3 petals are small, ovate, with yellow spots, and the lower 2 petals are larger, lanceolate, drooping, similar to tiger ears. Capsule ovoid. The breath is slight, the taste is slightly bitter. Microscopic identification of the leaf surface view of the upper epidermis cells polygonal, anticlinal wall is relatively straight, some wall holes are obvious, or horny texture; lower epidermis cell anticlinal wall wavy curved, stomata indeterminate, auxiliary cells 4-8. There are 1-8 cells in the head of glandular hairs, there are two kinds of multi-row and single-row in the stalk, the length of multi-row is 1300-5600 μ m, the upper single-row gradually increases to 7 rows, and the single-row has 1-4 cells with a length of 70-110 μ m. The diameter of calcium oxalate cluster crystal is 25-56 μ m. Clinical application in the treatment of suppurative otitis media: take several fresh leaves of Saxifraga, mash juice, filter with gauze, add appropriate amount of borneol, put it into eye drop bottle and set aside. When using, first wash the external auditory canal with 3% hydrogen peroxide to remove the purulent secretion, and then take Saxifraga solution ear drops, 1-2 drops each time, 3 times a day. 31 cases of suppurative otitis media were treated, 25 cases of acute otitis media were cured in an average of 3 days, and 6 cases of chronic otitis media were cured in an average of 7 days. Saxifraga has small plants and beautiful leaves. The stem is long and prostrate, and the stem tip bears a small plant. It is suitable to be planted in rock garden, wall and wild interest garden. Application: with the popularization and planting of perennial herbs, there are more applications under the green space Arbor forest, and the growth is still good. Such as Shanghai Minhang humin Road Construction Bank, Yanzhong Green Space, Dongan Park and so on. It is worth popularizing, can be planted under the big trees in the old green space, the land can be used, and it can also be planted next to buildings or rocks, which is more effective. Continue the scientific name of Saxifraga is very wonderful. It translates literally from Latin to rock cutter because Saxifraga likes to grow at the foot of the mountain behind the sun and in rock crevices. For a long time, maybe you can really cut the rock! Therefore, the flower language of Saxifraga is-continuous. Those who are blessed by this kind of flowers are extremely patient and can persevere and slowly accumulate into great achievements. It should be quite suitable to be a scholar. Saxifraga birthday flower April 12 Saxifraga picture
