Sex likes warm, humid and sunny environment, but avoid exposure in summer, which is more resistant to drought and shade. The suitable temperature is 20~25C, and the temperature in winter should not be lower than 5 C. It is suitable for being born in loose and fertile sandy loam with good drainage for fear of water accumulation.

Rosa davurica will not release toxic gas, and indoor planting is harmless to human body and can beautify the environment. Rosa davurica is a Euphorbiaceae plant. There are more than 2000 species of Euphorbia plants in the world, and there are more than 200 species in China, among which the single wood, poinsettia, deciduous wood and overlord whip are all brothers of Euphorbia, Euphorbia, Euphorbia, Euphorbia, Euphorbia and Euphorbia. The common feature of Euphorbia plants is that white milk will be secreted from the wound after the tree is injured. This kind of milk is a diterpenoid compound with special structure and toxicity. It is a favorable weapon for plants to protect themselves and prevent the invasion of pests and diseases in the process of evolution. Not only that, when the Rosa davurica fruit blooms, its flower stalk will secrete colloidal mucus, which can stick to insects. It turns out that this is also its line of defense to protect itself from pests. Rosa davurica fruit grows slowly, only about 10 cm long every year. But its life span is very long, and potted plants can live for more than 30 years. The flowering period is also long. If the light and temperature are suitable, it can be opened all year round.

Edit the propagation mode of this paragraph.

Mainly by cutting propagation. Cuttings can be carried out throughout the growth period, but it is best to carry out them in May-June, with high survival rate. Select the branches that matured last year and cut them into a section of 6- 10 cm, preferably the top branches. White milk flowed from the wound. Wash with warm water and dry before inserting into the sand bed. Keep it slightly dry and take root about 30 days after transplanting.

Edit this potted technology

Potted plants should be changed every spring. Don't water them too much. Sufficient water is needed in the summer and autumn growth period, and fertilization is required every month 1 time. In winter, the temperature is low, the leaves fall off, and the potted soil should be kept dry. Flowering in March-June and 65438+February, the flowers can continue to bloom when the soil moisture is kept moderate, and the flowers can continue to bloom when the room temperature is above 15℃ in winter. When plants grow too crowded and dense, you can prune the whole plant before new leaves grow in spring.

The cultivation essentials of editing this paragraph

Warm light: Tiger thorn adapts to warm environment and is not cold-resistant. Leave the house at the end of April or early May, 10~ 1 1 enter the house. Overwintering management should be kept above 65438 00℃. Low temperature leads to defoliation and dormancy. Cold winter room temperature 15~25℃, that is, flowers bloom continuously. After the room, it should be placed on the windowsill facing the sun, especially during flowering, and the light should be strengthened to make the flowers bloom for a long time. Insufficient light, dark color, little or no flowers. Control watering: Tiger thorn is drought-resistant, and it can be watered once every night in high temperature season and once every 2-3 days in early summer and late autumn. Do not accumulate water, and pay attention to drainage after rain. Water should be poured every 15~20 days in winter, and it is advisable that the basin soil is not dry. Water should be controlled during dormancy, and the soil in the basin should not be wet, because water is easy to rot the roots. Too much watering during flowering will cause flowers to fall. Correct fertilization: Tiger thorn does not require high soil fertility, is barren, and does not like thick fertilizer. When potted, choose sandy loam with good drainage, mixed with humus soil and pastoral farming soil. In 2002-2003, the pot was changed once, and a few hoofs were put at the bottom of the pot as base fertilizer, and no fertilization was needed during the growing period. When watering in May-August, topdressing can be done once every half month with thin liquid fertilizer soaked in decomposed oil residue, chicken and fish viscera. Too much fertilization, long white branches, only long leaves and no flowers. Modeling pruning: improving the viewing level of tiger thorns depends on reasonable pruning and artistic modeling. From June to July, mature plants will cut off long branches and irregular and weak branches, or cut off the top to promote them to grow new branches under the incision, so that there will be more flowers at the top of the branches. At noon in summer, when the branches are soft, the crown is shaped and processed to make bonsai. In winter, it can be modeled according to the indoor location, and the branch tray can be tied into a spherical shape, a fan-shaped radial shape or an umbrella-shaped inverted shape. After artistic modeling, the tiger thorn flower bonsai is not only sparse, but also strong and unyielding, elegant and bodybuilding.

Rosa davurica fruit has special properties and slow growth, which is only about 10 cm long every year, but its life span is very long, and potted plants can live for more than 30 years. The flowering period is long, and it can be opened all year round if the light and temperature are suitable.

The branches of Rosa davurica are not easy to branch, but will grow very long, with few flowers and messy posture, which will affect the appreciation. Therefore, they should be pruned in time every year to make them grow more new branches and flowers. Generally, two new branches can be born after pruning.

Rosa davurica has a well-developed root system and vigorous growth, which can be used as the rootstock for grafting fairy finger and crab claw orchid, but it belongs to shallow root system and spans far, with few root hairs. Rosa davurica likes warmth and is not cold-resistant. It grows best at around 22℃ during the day and around 65,438 05℃ at night. When it is kept at 65,438 05℃ to 20℃ in the greenhouse, it can bloom all year round. When the temperature is reduced to 10℃, the fallen leaves will turn into semi-dormancy, and new leaves will be released in the next spring to continue flowering.

Tiger thorn plum likes light. The more sunshine before flowering, the brighter the flowers will be. If it lasts for a long time, the color will be dim. If it is kept in the shade for a long time, it will not bloom. Also pay attention to keep the air circulating.

Rosa davurica fruit can be used as base fertilizer by using cultivated soil to pad hoof horn pieces, and fertilized once every half month during the growing period. After autumn, fertilization should be stopped to prevent root rot. Rosa davurica is drought-tolerant, so watering in spring and autumn should be dry and wet. Water once a day in summer, prevent waterlogging in rainy season, do not water in winter, and the basin should not be wet for a long time; Water should also be controlled during flowering period, which is easy to cause falling flowers and rotten roots.

In late spring and early summer, May-July, the cuttage of Rosa davurica is the easiest to survive. Select stout branches, about 10cm ~ 15cm long, dry the white pulp flowing from the incision, coat it with plant ash, and dry it in the shade for 2 ~ 3 days. After the wound is dried, insert it into plain sand, pour it thoroughly with water, then pour it less, and then pour it after the basin soil is slightly dry.

Tiger thorn flower is easy to cultivate, with long flowering period and bright red bracts. It is a popular potted plant. Because the young stems of Rosa davurica are soft, they are often used to shape peacocks and become fine products in hotels, shopping malls and other public places.

The white juice of tiger thorn flower contains toxins, which may cause redness and swelling in skin contact, and may cause edema in mouth and throat if eaten by mistake. It won't cause cancer.

Edit this bonsai work

Tiger thorn plants are small, with straight trunks and naturally shaped branches and leaves, which can be seen from small to large, showing the charm of big trees. Can be planted with stones alone, can also be planted in pots, made into jungle bonsai. Cut off some branches and leaves that affect the effect before planting. The number of plants planted in each pot should be odd, even is acceptable, but it should not be symmetrical. Different plants can be planted according to the size of flowerpots and plants. When planting, we should consider the overall effect, make it harmonious and unified, have certain changes, achieve high and low order, good density, avoid overlapping branches, pay attention to the growth space between trunks, and leave room for future growth. After planting, it can be matched with rocks and covered with moss to make it quiet in forests and valleys, and decorations such as huts, figures or deer and cranes can be placed as needed to increase interest. Because of its short plants and fine leaves, tiger thorn can also be used as an ornamental plant in rock bonsai.

Tiger thorn is native to the south of the Yangtze River valley in China, and grows in humid places in the mountains. It likes warm and humid semi-cloudy environment, not cold and dry, and is afraid of exposure to the hot sun. Generally, it can be placed in the shade of trees or in the morning, but it can be maintained in the southeast without strong light at noon and afternoon and other places without direct sunlight. Don't change the placement position frequently, otherwise it will cause fallen leaves. Keep the soil moist, but don't accumulate water, especially in spring, to avoid accumulating water to avoid root rot. Water is often sprayed on the plants to increase the air humidity, so that the leaves are moist and bright, and the decomposed dilute liquid fertilizer is applied every half month during the growing period. Tiger thorns grow slowly, so they can be trimmed slightly at ordinary times and cut off some branches that affect the tree shape to keep the bonsai beautiful. To avoid strong winds in winter and early spring, you can move to a bright place indoors and control watering to make the soil slightly dry. If there is heating in the room, you can often spray plants with water close to room temperature to avoid falling leaves due to air drying. Change the basin every 2 ~ 3 years, and the basin soil should be acidic sandy soil with rich humus and good drainage.

Edit this section of pest control.

Stem blight and rot are the main hazards, and 800 times of 50% captan solution/kloc-0 is sprayed every half month. Pests do great harm to whiteflies and scale insects, so 50% chlorpyrifos EC 1500 times solution should be sprayed.
