Paulownia has good material and wide application

  1. The material is light and tough
    To evaluate the quality of wood, bulk density and strength are important standards. The higher the strength is, the lighter the bulk density is. Paulownia wood is one of the lightest wood on the earth. Its air dry density is 0.23-0.40 g / cm3, which is about 40% lighter than ordinary wood. Its biggest advantage is that it is light and tough.
  1. No warping, no deformation
    Because of its small coefficient of shrinkage, the trees do not bend and do not warped and not deformed.
  1. Moisture proof
    The dried tung tree is not easy to absorb moisture and moisture, and has a high degree of preservation.
  1. Fire resistance
    The thermal conductivity of Tung wood is smaller than other ones. Generally, the combustion point of wood is about 270 degrees, and the burning point of Tung wood is 425 degrees, which is a rare feature.
  1. Wear resistance
    Although the Tung wood is light, it is not easy to wear. The Tung wood is used as an air box, and the pull rod is worn back and forth, but the box plate is not easy to wear.
  1. Beautiful texture and bright color
    Tung wood has a bright, beautiful and delicate texture with silk, and the natural pattern is very good.

  2. Strong sound guidance
    Tung wood is indispensable for making musical instruments. Regardless of weather changes, it can stabilize the timbre, so it is called “Qin Tong”. For example, Yangqin, pipa, Liuqin and even Qinhu are all made of tung.

  3. Easy to carve and dye
    Tung wood is not easy to split, but the wood is soft, easy to process, easy to carve and easy to dye. It can be used as beam, purlin, door and window, ceiling, tile board, room partition and so on.

The leaves and flowers of Paulownia are a kind of feed that pigs, sheep and rabbits love to eat
It is recorded in the natural history that “Tong Hua and ye pigs are extremely fattening and easy to raise (‘easy to raise’, that is, not easy to get sick)”. According to the Institute of forestry, Chinese Academy of Forestry Sciences, the leaves and flowers of Paulownia were analyzed. The results showed that the dry leaves contained 4.89% soluble sugar, 1.5% starch and 20.69% crude protein; The dried flower contains 10.58% soluble sugar, 8.15% starch and 15.69% crude protein. The analysis shows that the leaves and flowers of Paulownia are rich in nutrients. Therefore, the development of Paulownia production can promote the development of animal husbandry.

The development of Paulownia production can also increase the source of fertilizer and improve soil fertility
According to the determination: Paulownia leaves contain 2.96% nitrogen, 0.19% phosphorus pentoxide, 0.41% potassium. A 7-year-old paulownia tree can produce about 40 kg of fresh leaves a year. The leaves of 4 paulownia trees are equivalent to 73 kg of soybean cake (containing 6.5% nitrogen) or 10.5 kg of urea (containing 46% nitrogen). These leaves fall into the field, after decay, can add a lot of humus to the soil, improve soil structure, improve soil fertility, and provide a lot of nutrients for crops. Because Paulownia Leaves and flowers contain soluble sugar, starch, crude protein and nitrogen, phosphorus and potassium comparable to some legumes, Paulownia is not only a “Woody feed”, but also a “Woody fertilizer”.
