Summary: The catalpa tree is beautiful and upright. Are there fast-growing catalpa varieties?

Catalpa wood is not a fast-growing tree, and it is not widely planted in rural areas. It is not as common in rural areas as trees such as poplar, paulownia, locust, and elm, but the catalpa tree, with its tall, upright stature, pale red and elegant flowers, dense and broad leaves, and beautiful crown shape, covers its branches with blossoms in flowering season, making viewers linger. It is a famous ornamental arbor in our country, and its presence can be found in many famous scenic spots in our country, such as the Forbidden City and the Summer Palace.

Catalpa wood has three major uses: ecological greening, industrial timber, and medicinal value.

Ecological greening

The catalpa tree is tall and straight, with a large and dense crown and deep and developed roots. The catalpa tree has bright and abundant flowers, and its tree shape and posture are graceful. It is an ecological greening tree with functions of purifying air, reducing noise, improving air quality, protecting against soil erosion, windbreak and sand fixation, and ornamental value. It is mostly planted in urban parks, tourist attractions, and farmland, highway, and riverbank shelterbelts.

Industrial timber

Catalpa wood is a high-grade timber among broadleaf trees, and it is one of the rare timber tree species in our country, specially used to process high-end goods and special products. The density of catalpa wood is very high, equivalent to the density of nanmu; its impact resistance ranks among the top among broadleaf forest trees; the trunk is straight, the wood grain is attractive, and the texture is tough and dense, sturdy and durable, with good insulation performance, resistance to water and moisture, resistance to decay, and resistance to insect damage. Because its grain is attractive and its paint and adhesive properties are good, it is an excellent overlay and decorative material for artificial boards.

Medicinal value

The roots, bark, and seeds can all be used as medicine. It is cool in nature and bitter in taste, and has the effects of clearing heat and detoxifying, dissipating blood stasis, and reducing swelling. External application can treat bruises and injuries. The tender leaves and flowers of the catalpa tree can also be eaten.

Research and development of fast-growing catalpa wood

The catalpa tree is a tree species unique to our country, with a history of more than two thousand years. It can be planted in both the north and south of our country. Although the catalpa tree has wide uses and high economic value, it is rarely seen in rural areas. This is because the catalpa tree grows slowly and has a long growth cycle. In addition, human logging and use have caused the number of catalpa trees to drop sharply and be on the verge of exhaustion, while the price of catalpa wood has continued to rise, with the price per cubic meter being 2--3 times that of ordinary wood.

Therefore, after many years of arduous research by a scientific research team, fast-growing catalpa trees and supporting fast-growing cultivation techniques have finally been developed. Fast-growing catalpa trees combine the advantages of ordinary catalpa trees and also have the advantage of fast growth. The growth of fast-growing catalpa trees can be increased by more than 30% compared with ordinary catalpa trees.
