The dragon blood tree is also a horse cane tree, a narrow-leaved dragon blood tree, a long-flower dragon tree, which can be used for garden viewing, but it cannot be used as firewood, but also called "not a tree." The dragon's blood tree is extremely body-building, and the leaves are colorful and beautiful. How is the dragon blood tree raised, and what are the breeding methods and precautions for the dragon blood tree?
Basic information of the dragon tree
The dragon blood tree is an evergreen shrub with a height of up to 4m, grayish-skinned, leaves sessile, and leaves clustered on the top of the stem, 40 to 90 cm long and 6 to 10 cm wide.

People call it a dragon tree, some The leaves of the variety are embedded with white, milky white and beige stripes, which are also called tricolor dragon trees.
Dragon blood tree culture method
1. Reproduction: The dragon's blood tree is propagated by cutting method. The technique of cutting the skill of the plant is used as a cutting material, cut into 5~10 cm sections, and inserted in the upright or flat way. Or a rocker is a media bed. The dragon blood tree can also be rooted by the water culture method. The specific method is to insert the cut stem segment into the water, the section should be smooth, and the upper end can be coated with wax to prevent evaporation of water. This is particularly important during the dry season, with the lower end immersed in water 2 to 3 cm and the temperature above 25 ° C. The water and container should be kept clean. The leaf-rooted dragon tree has a faster rooting rooting. It can be rooted in the basin for 3 to 4 weeks. The rooting of the stem is slower. It takes 2 to 3 months for the dragon tree to grow new roots and sprouts.
2, lighting: Dragon Blood trees are very adaptable to light, dark and bright can be placed. The dragon blood tree likes the light but is afraid of the sun exposure. The dragon blood tree likes the warm and humid environment and is resistant to the sun and the sun. The more light the dragon tree is, the more brilliant the leaves are.
3, temperature: Dragon's blood tree is not cold-resistant, winter temperature is about 15 ° C, the lowest temperature is 5 ~ 10 ° C, the temperature is too low, due to lack of water absorption in the root system, the tip and leaf edge of the dragon blood tree will appear yellow-brown plaque. It is best to make the dragon tree sleep in winter, and the dormant temperature is 13 °C. When the temperature is high in summer, the dragon's blood tree needs to be properly shaded.
4. Soil: The dragon blood tree likes sandy soil with loose, fertile and permeability. An appropriate amount of organic fertilizer and ferrous sulfate can be added to the nutrient soil.
5, watering: Dragon Blood trees have strong drought resistance, watering should not be too much, to prevent trunk rot. You can water the water once every ten days or half a month to keep the pot soil slightly dry.
6. Fertilization: Fertilization of dragon blood trees should be applied with thin fertilizer. Fertilizer should be applied with less nitrogen fertilizer, and more phosphorus and potassium fertilizer should be applied to avoid excessive application of nitrogen fertilizer. The golden yellow markings of dragon blood tree leaves are not obvious, and the dragon blood trees should stop in winter dormancy. Fertilize.
Transplanting: first use a knife to remove a layer of skin, then fertilize the dragon's blood tree, penetrate the water, check and replenish water at any time, and slowly the dragon's blood tree will germinate. Available humus soil, peat soil, river sand One part is mixed as a substrate, and the dragon blood tree is cultivated under the condition of 70-80% shading.
7. Insect-proof technology: When the larva enters the wintering period, the affected part of the stem can be watered with pesticides, and the wintering larvae can be killed 2 times to 3 times. In the early stage of larval damage, apply 30 times of omethoate emulsifiable concentrate to the affected area. Eliminate the source of insects, and concentrate on burning the dragon's blood trees that have been severely eliminated and kill the insect source. Do not cause the majesty of all flowers and plants to be infected because of the value of a dragon's blood tree. After all, "when broken, continue to be chaotic."
Dragon Blood Tree Breeding Precautions
1, dragon blood trees like warmth, fear of cold, hi-light and fear of sun exposure, the most suitable for growth in a warm and not hot environment. The spring, summer and autumn seasons are the strong season for the growth of dragon trees. During this time, the supporters must fully satisfy their water, nutrients, temperature and needs to make them grow stronger.
2, indoor breeding dragon blood trees should be in a place with sufficient light, if the light money is too weak, the markings on the leaves of the dragon blood tree will turn green, the leaves at the base are yellow, and the ornamental value is lost.
3, in the winter dormant period to stop fertilization, control watering, generally placed indoors for winter, you can water once every ten days and a half, to maintain a little dry soil, so that it is safe to winter. If there is no sunlight for a long time, you can turn on the lights at night, put the dragon blood trees under the 40-watt light, and carry out artificial light-assisted illumination to ensure the beautiful appearance of the leaves. In the evening, the dragon's blood tree should be placed inside the curtains, and the thick air curtains should be used to block the cold air, or the flower pots should be placed in the warm corner of the corner to make it safe for winter.
1. Temperature difference, strong and durable
The new version of the Ceramic pot, the material is fine, usually made of some kind of ceramic material is not afraid of hot and cold temperature difference. Some glass ceramic pot physical properties can reach 500℃ heat temperature difference, and do not deformation, cracking or broken, will not lose glaze and luster. Glass ceramic pot inner wall and appearance is more smooth, no odor residue, but also rejected the traditional casserole and clay pot easy to adhere to stains and burn black shortcomings.
2. Strong heat collection function, nutrition and energy saving
Ceramic tank selection of ultra-heat resistant material, heat storage, good insulation, can maintain high thermal state with minimum firepower. Therefore, the food in the soup pot is easy to cook. And because the cooking time is relatively short, energy saving is more environmentally friendly. In particular, the appearance of the transparent glass ceramic pot makes it easier for housewives to observe the temperature of cooking ingredients, so that it can be adjusted at any time, thus effectively reducing the loss of nutrients caused by cooking food for too long.
3. Not easy to age, often new
Ceramic POTS do not readily absorb food odors and stains. From cooking to serving, the non-absorbent material prevents the pot from aging easily and from cracking due to temperature differences like a casserole.
