Is there a fast-growing variety of catalpa trees that are beautiful and tall and straight but grow very slowly?

Abstract: the catalpa tree is beautiful, tall and straight. is there a fast-growing catalpa tree variety?

Catalpa is not a fast-growing tree, and it is not widely planted in rural areas, and it is not as common as poplar, paulownia, locust, elm and other trees in rural areas, but catalpa with its tall, tall and straight posture, light red and elegant flowers, dense and broad leaves, beautiful crown shape, full of flowers in the flowering season, allowing visitors to linger, is a famous ornamental tree in horticulture in China, leaving its figure in many famous scenic spots in China. Such as the Imperial Palace, the Summer Palace and so on.

Catalpa mandshurica has three functions: ecological greening, industrial wood and medicinal value.

Ecological greening

The trees of Catalpa mandshurica are tall and straight, the crown is large and dense, the roots are deep and developed, the flowers of Juglans mandshurica are colorful and blooming, and the tree shape is graceful. It has the ecological greening trees of purifying air, reducing noise, improving air quality, protecting soil and water loss, preventing wind and fixing sand, and ornamental. It is mostly planted in urban parks, tourist attractions and farmland, highways and river shelterbelts.

Industrial wood

Catalpa is a kind of high-grade wood in broad-leaved trees, and it is one of the rare timber species in China, which is specially used for processing high-grade commodities and special products. The density of catalpa wood is very high, which is equivalent to that of nanmu; the impact resistance is in the forefront of broad-leaved forest trees; the trunk is straight, the wood texture is good, the texture is tough and dense, strong and durable, good insulation, moisture resistance, rot resistance, not easy to moth, because of its good texture, good paint and adhesive, wood-based panels are good veneer and decorative materials.

Medicinal value

Roots, bark and seeds can be used as medicine, cool and bitter, with the effect of clearing heat and detoxification, removing blood stasis and detumescence, external application can treat injury, and young leaves and flowers of catalpa tree can also be eaten.

Research and Development of Fast-growing Catalpa

Catalpa is a unique tree species in China, which has a history of more than 2000 years. It can be planted in the north and south of our country. Although Catalpa has a wide range of functions and high economic value, it is rarely seen in rural areas. This is because the slow growth rate and long growth cycle of catalpa trees, coupled with man-made felling and utilization, make the number of catalpa trees decline sharply and on the verge of exhaustion, while the price of catalpa wood is all the way up, and the price per cubic meter is three times that of ordinary wood.

So now after years of painstaking research by the scientific research team, we have finally developed fast-growing catalpa trees and fast-growing cultivation techniques. Fast-growing Liriodendron not only has the advantages of ordinary Liriodendron, but also has the advantage of fast-growing and fast-growing. The growth of fast-growing Liriodendron can be more than 30% higher than that of ordinary Catalpa.
