Melaleuca: Melaleuca metal deep-rooted tree species with distinctive morphological characteristics, upright trunk, slender and soft branches, red branches, good toughness and strong wind resistance, and has very good growth potential at the seaside. In Guangzhou, autumn, winter and spring are golden yellow, and summer is goose yellow due to high temperature.
Melaleuca leaves are fragrant and pleasant, and its aromatic oil is one of the precious cosmetics spices in the world.
The ecological habits of Melaleuca Melaleuca also have a wide range of adaptability to soil, from acidic to limestone soil and even saline-alkali soil. Strong resistance to pests, drought and waterlogging, suitable for water growth, salt tolerance and strong wind resistance. It is a rare and excellent landscaping tree species in coastal areas, especially suitable for afforestation in coastal reclamation areas.
Melaleuca trees grow fast, and can be pruned into a 3-meter-high tower shape in 2-3 years, and can be cultivated into street trees with DBH 5-6 cm and branch height 1.6-2 meters in 3-4 years. The trunk of an adult tree can reach1.5 ~ 20cm thick, and the height of the tree is 6 ~ 8m, forming a cone with a crown width of 3 ~ 5m. At the same time, it has good branching performance, pruning resistance and crown, which makes the crown form a bright golden cone with strong visual effect. In addition to the natural form, it can usually be trimmed into various shapes such as sphere, umbrella, hedge and pyramid.
It has a wide climate adaptation area, and the suitable planting range is from Hainan to the south or even the north of the Yangtze River Basin, and it can withstand the low temperature of -7℃ to-10℃. 1999 was first introduced to Guangzhou, and it grows well all year round, especially in winter. In 2000, the cold resistance test of seedlings was carried out in Yueyang and Chongqing, Hunan Province, and all of them could safely overwinter in the open field. The overwintering experiment in Chengdu in 2005 has always performed well.

The propagation of Melaleuca Melaleuca can be carried out by softwood cutting (cutting propagation) and high-altitude layering propagation. However, there are many cuttings, usually in April-August when there is more rain and the temperature is not too low at night.
1, cut and cut
Select semi-mature, robust and pest-free branches as cuttings. In order to avoid water evaporation, you can pick strips in the morning. Cutting substrate can be vermiculite and peat, or fine sand and peat. Rinse with clean water immediately after insertion.
2. Post-harvest management
Temperature: It is best to keep the temperature at 20℃ to 30℃. Too low temperature will slow down rooting, and too high temperature will easily cause cuttings to rot.
Humidity: pay attention to keep the cutting substrate moist after cutting, but don't make it too wet, otherwise it will cause rot. At the same time, we should also pay attention to maintaining a high humidity, but we should pay attention to the fact that the humidity should not be too high after rooting.
Drug treatment: Because of the high humidity during rooting, leaves and stems are easy to rot, and spraying carbendazim, chlorpheniramine or thiophanate methyl 800 times can prevent it.
Function, use and ornamental application of Melaleuca.
1, Melaleuca hedgehog grows fast. It can be trimmed into a 3-meter-high tower shape in 2 to 3 years, and cultivated into a hedge with DBH of 5 to 6 cm and height of 3 to 4 meters in 3 to 4 years. The trunk of an adult tree can reach 15 to 20 cm thick, and the tree is 6 to 8 meters high, forming a cone with a crown width of 3 to 5 meters. In addition, its leaves are golden yellow or goose yellow all year round, so it is the first choice for high fences and green walls.
2. Ornamental trees in villas and communities
Good branching performance, even without pruning, can make the crown form a bright golden cone and produce a strong visual effect. If such a Melaleuca tree with pleasant leaves is planted in the courtyard of a residential area or villa, there will be a different artistic conception.
3. Garden modeling
Melaleuca trees have good branching performance and are resistant to pruning, and can be pruned into various shapes such as spheres, umbrellas, hedgerows and pyramids. More and more people choose to use it as a garden shape.
4. Ground cover color block
Melaleuca grandiflora seedlings grow rapidly, and their branches are soft and resistant to pruning. Moreover, the combination of its golden colors in four seasons and colorful tree species such as red cars as color blocks also makes people in the industry very optimistic, and has begun to promote it as a ground cover plant.
5. afforestation
Melaleuca is drought-resistant and waterlogged-resistant, suitable for water-side growth, and also resistant to saline-alkali and strong winds. Therefore, it is a rare and excellent landscaping tree species in coastal areas, especially suitable for afforestation in coastal reclamation areas.
