It is not easy to transplant a Pinus taiwanensis tree that has grown naturally for decades to the tip of the pen peak, which is less than 0.5 square meters and has no soil. To this end, the Landscape Bureau of Huangshan Scenic Area set up a special group in 2003, whose members covered forestry, tree transplantation, bonsai, gardening, ancient tree protection and other disciplines.
The "dream pen gives birth to flowers" scenic spot, with a peak height of 44.4 meters and a main rock mass thickness of 3.8 meters, is top-notch and has no soil conditions for planting trees at all. In August 2003, the Landscape Bureau of Huangshan Scenic Area organized relevant professional and technical personnel to make full use of the natural crevices in the southeast and west of Bifeng Mountain and fill the planting site with fresh and fertile pine humus soil, which provided the necessary guarantee for the root extension of transplanted trees and the supply of soil and fertilizer.
From 1 1 in 2003 to 1 in 2004, the Bureau of Landscape Architecture carefully selected the trees to be planted in the core scenic area according to the tree shape and height of the original pine, and three trees were identified by the expert group on the spot. In the spring of 2004, they were cut, trimmed and shaped for future use.
On March 25, 2004, the expert group dug, planted and transported the identified trees to the unknown hillside near Bifeng overnight. In order to transport the prepared trees to the top of Bifeng, the construction workers pulled a steel cable between Bifeng and the unknown peak opposite, and then installed pulley equipment on the steel cable. In this way, the planted pine trees "sat" on the cable car, climbed to the peak of Bifeng, and completed the work of transplanting, fixing, fertilizing and watering under the guidance of experts.
After 8 hours of intensive construction by the expert group and the implementation team, a 50-year-old Pinus taiwanensis with a height of 175cm, a ground diameter of 18cm and a crown width of 234cm×228cm was successfully transplanted.
The new tree cultivation uses vitality element, transpiration inhibitor and wound healing agent respectively, which makes the wound healing time of transplanted Pinus elliottii shorter, the root system recovers faster and the vitality recovers faster. After the completion of planting, the expert group renamed the newly planted pine tree as "disturbing longsong pine", and formulated "Regulations on Post-planting Management of disturbing longsong pine" and "Management Rules for/0/5 days after transplanting disturbing longsong pine".
After more than a year's careful care, at the end of March this year, the tree was confirmed by experts in six disciplines, including ancient tree protection and pest control in Beijing and Hefei, and the transplant project was successful. Experts believe that this achievement is of great significance to the restoration of famous landscapes in China scenic spots.
On March 28th, the news came from the Landscape Bureau of Huangshan Scenic Area. At the appraisal meeting of scientific and technological achievements in the whole province organized by the Provincial Science and Technology Department, the landscape restoration technology of Huangshan's iconic landscape-"dream pen gives birth to flowers" was successfully appraised by an appraisal committee composed of experts in forestry, forest protection, forest breeding, afforestation and cultivation.
Experts praised the resurrection technology to fill the gaps in the protection of world heritage resources, the restoration of famous landscapes, and the transplantation of trees in extremely harsh environments, and reached the leading level of similar projects in China.
On the summit with an altitude of1610m, a height of 44m and a top area of less than 0.4m, there is no shortage of water and soil, and the environmental conditions are extremely harsh. It is very difficult to transplant Pinus taiwanensis with a tree age of more than 50 years. This technology ensures the successful transplantation of transplanted plants. (Zhu Liwen Lin Huang)
