The bark of the local Catalpa bungeana is cracked and not smooth, and the bark of the fast-growing Catalpa bungeana is smooth and moist.

the local catalpa bungeana is planted, and the fast-growing catalpa bungeana is planted.

The catalpa bungeana itself is a fast-growing tree species, and the seeds of catalpa bungeana are abundant, so it is easy to raise seedlings. Catalpa bungeana grafted with catalpa is a kind of arbor, with the seedling growth of 3.5-4 meters and the ground diameter of 3.5-4 cm.

This shows that grafting can promote the growth of scions, which is an effective method to develop fast-growing fine varieties such as Catalpa bungeana. Then the Catalpa bungeana grown by grafting Catalpa bungeana is called fast-growing Catalpa bungeana, and thus the fast-growing Catalpa bungeana was born.

Advantages of Catalpa bungeana

Catalpa bungeana is deeply loved for its tall body, beautiful posture, excellent materials and wide applications. Catalpa bungeana has developed roots, strong soil-fixing ability, strong wind resistance, cold resistance and drought tolerance, and is an excellent tree species for wind and sand fixation and farmland protection. Because Catalpa bungeana is full of flowers, the growth period of Catalpa bungeana is slow, and it usually takes 4 to 5 years to become a mature tree.

Catalpa bungeana wood is scarce, and it has become a tight commodity in the wood market. The price of sawn wood per cubic meter of Catalpa bungeana wood is as high as 3,8 yuan, which is equivalent to 2-3 times the price of ordinary wood. The wood grain structure of catalpa bungeana is relatively fine, with fine lines and black spots. Basically, there is not much distortion and gap in the wood grain. Catalpa bungeana wood has tough texture, low density, warping and deformation, which is a big problem for finished zui, and it has no peculiar smell, easy processing, easy drying, easy carving and good insulation performance. It also has the advantages of not easy to be eaten by insects, wear resistance, corrosion resistance, moisture insulation, sound guidance and so on. It is widely used in musical instruments, crafts, military industry and other aspects.
