It is a new species of mosquito repellent tree that was discovered and launched only in recent years. It uses the unique citronellal substance on the leaf surface to evaporate into the air through high temperature evaporation to achieve the effect of repelling mosquitoes.

1. It has the following characteristics:

1. Ecological Mosquito repellent: The new mosquito repellent tree is rich in various aromatic natural essential oils such as citronellal and citronellol, which have mosquito repellent effects. Mosquitoes can be paralyzed after smelling this smell and lose their ability to bite. The higher the temperature, the higher the temperature. , the stronger the smell, the better the mosquito repellent effect.

2. Indoor mosquito repellent: In the summer evening, pick off the branches and leaves of the landscape mosquito repellent tree, smoke them in the room once, and they will disappear for 10 days and a half. Mosquitoes.

2. Morphological characteristics

Shrubs or small trees, 3-5 meters tall, green young branches, russet old branches, pubescent, with obvious lenticels. The leaves are opposite and are odd-pinnately compound leaves. Leaflets 5-9, oval, apex acuminate, with blunt serrations throughout. Inflorescences in cymes-like panicles, terminal.

3. Planting techniques:

It can be planted from after the leaves fall in winter to before germination in early spring. Dig a hole where it needs to be planted. The width and depth of the hole are 80 centimeters each. Apply about 20 kilograms of decomposed compost or soil fertilizer, and mix it evenly with the subsoil as base fertilizer. When planting seedlings, they should be planted squarely and firmly, and the soil should be filled and compacted. Pour the root thoroughly with water.

4. Propagation

Because the seeds of new mosquito repellent trees are mostly underdeveloped and cannot be used as seeds, seeds are rarely used for propagation. The asexual propagation method of root cuttings is used. In late February, select a strong and vigorous mother plant that is more than 4 years old, dig out lateral roots with a diameter of more than 0.5 cm, cut into root segments about 15 cm long for cuttings, cut the upper end flat, and cut the lower end into a bevel. 10 cm cuttings. After planting, water thoroughly and cover with a plastic shed to increase warmth and moisture. After the cuttings take root and germinate, the shed is removed, the seedbed is managed, and after one year of cultivation, they are released from the nursery for planting.

In addition, mugwort leaves and jasmine flowers can repel mosquitoes.
