The value of paper mulberry

Many people may not know about the Paulownia tree. The ornamental value of this plant is not very high. However, due to its strong adaptability, fast growth rate and easy reproduction, the value of Paulownia tree is still quite high. It can be used for papermaking, medicine, sand control and forest consolidation. There are many advantages to planting paulownia. If you are interested in this type of vegetation, it is necessary to fully understand the value of paulownia. Let’s take a closer look below.

Current status of paper mulberry planting

After the implementation of the project of developing paulownia resources with bioengineering technology, if every farmer adopts scientific planting and maintenance methods to plant paulownia, a forest will be established in 1 to 2 years, with an annual yield of 2.5 to 3 tons of paulownia dry matter per mu, and an output value of more than 6,000 yuan per mu.

After dwarfing (after the mulberry tree is planted, in April and May of the same year, when the trunk diameter is 3 cm, the main trunk is cut 30 cm from the ground, leaving 3 to 5 branches as the first-level trunk. In June and July, 30 cm of branches are pruned from the first-level branches, and 3 to 5 branches are left on each branch to form the third-level branches. In October and November, 30 cm of branches are pruned from the third-level branches. At this time, the mulberry tree is more than one meter high and is trimmed into shape. All branches that grow 30-40 cm before they become lignified are picked and no branches are left. It can be harvested 3-5 times a year. Once planted, it can be harvested for 20-30 years.

The Prospect and Value of Paper Mulberry Planting

Economic Value

The bark contains a very high fiber content, the fibers are very long and fine, and of excellent quality. It is a high-quality raw material for the production of rice paper and banknote paper.

The leaves are rich in protein, amino acids, vitamins, carbohydrates and trace elements, and are a pure natural raw material for the production and processing of livestock feed.

The fruit, root bark and bark serum all have good medicinal effects. The fruit is a tonic; the root bark is a diuretic; the bark serum is used to treat ringworm and bites from snakes, bees, dogs and insects.

The bark, stems and leaves contain tannins, from which tannin can be extracted.

Ecological Value

The lateral roots of the paper mulberry are well-developed and have a strong ability to sprout. They can compact the soil, conserve water and soil, and prevent wind and sand. They have a significant effect on the slope protection of reservoirs, dams, ponds, and weirs.

Paulownia has a strong ability to absorb sulfur dioxide and is a high-quality greening tree species in industrial and mining areas. Large-scale planting can reduce the formation and harm of acid rain. Paulownia has the ability to absorb and resist pollutants and dust. Planting it on roads and in towns can purify the air and improve the environment. Vigorously developing mulberry forests in rocky deserts and low-lying tidal flats can make the barren land green, green the environment, promote ecological balance, and beautify people's lives.

Large-scale planting of paulownia plays a positive role in greening barren hills, strengthening embankments, controlling soil erosion, and improving the ecological environment. Paulownia is easy to survive, easy to manage, grows fast, and has strong resistance to diseases and pests. It has a short investment payback period and high benefits, making it a good tree species for afforestation. Planting paulownia trees and processing their leaves into feed. This green feed, which does not contain hormones, pesticides, pollution or environmental hazards, allows pigs to grow fast, have a high slaughter rate and good meat quality. It is truly green food that can break through the "green barriers" of Western countries and continuously enter the international market, earning foreign exchange for the country's exports and achieving very good economic benefits.
