Why does Huangshan welcome pine use a supporting rod?

There is continuous snowfall in Huangshan Mountain, and 24 support poles protect the welcome pine.

Recently, the cold wave hit the south, and extreme weather of rain, snow and low temperature occurred in the south of China since 2008. The temperature at the top of Huangshan Mountain is as low as -9℃ to -2℃, and sleet freezes rapidly, which greatly affects Song Qi, the first of the "five wonders" of Huangshan Mountain. The protection of ancient and famous trees such as "national treasure" welcoming pine is under great pressure. In order to make the 800-year-old welcoming pine safe and sound, the local emergency team was sent to guard it day and night, with only 24 support rods.

On the left side of Yuping Building in Huangshan Mountain, the welcoming pine above Manjusri Cave is born of gravel, with an altitude of10m and a DBH of 0.64m.. It is at least 800 years old. Welcome pine is the landmark landscape of Huangshan Mountain and one of the symbols of Anhui Province. From the iron painting welcoming pine in the Great Hall of the People to the station pier, she has her figure, which is a national treasure ancient and famous tree.

According to the meteorological warning information, Huangshan Scenic Area launched the emergency plan for snowfall of ancient and famous trees, and strictly followed the requirements of "one tree and one policy" to protect the welcoming pine. The staff used bamboo, bamboo and glass fiber support rods to add emergency support rods to the welcome pine. With the increase of snowfall in Huangshan Mountain, by 2: 00 am on the 27th, the staff had installed 24 support poles for welcoming pines and monitored them in shifts.

In front of Yuping Building in Huangshan, technicians from the garden department and staff from the emergency squad of Yingkesong stood here 24 hours a day to protect Yingkesong on the spot. They pay close attention to the process of low temperature, rain, snow and freezing weather, scientifically analyze the data such as the ice layer on the tree surface, the thickness of snow and the bending degree of branches, and selectively take protective measures such as blowing, shaking snow, pulling fibers, protecting pounds and supporting.

Nursing welcome pine is skillful. When the snow has just fallen on the tree and has not frozen, you can gently shake it off against the branches with bamboo, or gently blow off the snow on the pine branches with a wind extinguisher, or spray water with a power sprayer to make the snow melt as soon as possible. However, this round of ice and snow lasts for a long time, and freezing rain will be added from time to time. When the weather is cold, snow falls on pine trees and turns into ice.

Once the snow on the welcome pine is frozen, you can't hit it with a pole, otherwise it will damage the branches and pine needles. At this time, every branch can only be supported by scaffolding. To this end, Huangshan Scenic Area has tailored nearly 60 support rods made of bamboo, Phyllostachys pubescens and fiberglass to help reduce the burden and pressure of welcoming pine.

65438+1On October 24-27, Huangshan Scenic Area organized 10 emergency teams for the protection of ancient and famous trees, and10 more than 40 people participated in the protection. More than 260 support rods were used, and only 24 support rods were made by National Treasure Welcome Pine. At present, 137 ancient and famous trees listed in the technical archives of Huangshan Scenic Area are safe and sound. At the same time, the relevant departments of the scenic spot are making every effort to send more personnel to shovel ice and snow, clean up fallen trees and dredge tourist roads.

It is precisely because of their silent persistence and meticulous care that the "national treasure" welcoming pine can stand proudly on the top of Huangshan Mountain with open arms in such extremely cold freezing rain and snow. The rain, snow and freezing weather is not over yet, and their protection continues. Here, we want to say to everyone in Huangshan who is still struggling with snow and ice during the temporary closure of the scenic spot, you have worked hard!
