Qilin pine is one of the top ten famous pines in Huangshan. Born at 1470 meters above sea level on the road from Beihai to qingliangtai. The trunk is 1.5 meters long and divided into two branches. The two wings are high and low. It looks like a unicorn. The tree is about 500 years old. Many strange pines have no soil under them, so they have to take root in the cracks of granite in the mountain. Because of the steep and slippery cliffs, it is difficult to retain rainwater. In order to find water source, the roots have to continuously dive into the faults with water in the deep rock mass, so the length of the roots is often several times longer than that of the trees. In addition, the roots have to make such arduous efforts to absorb the nitrogen and phosphorus in the rock bit by bit, and take the potassium from the fleshy feldspar as the existing mineral.

brief introduction

Kylin is born of pine and broken stone, grows near the cliff, has thousands of twigs, green and straight. It's vigorous, straight and impressive, but its bottom-up environment is extremely difficult. Many strange pines have no soil, so they have to take root in the cracks of granite. Because of the steep cliffs and the difficulty in retaining rainwater, in order to find water, the roots have to continuously penetrate into the faults with water in the deep rock mass, and the length of the roots is often several times longer than that of the trees. In addition, the roots have to make such arduous efforts to absorb the nitrogen and phosphorus in the rock bit by bit, and take the potassium from the fleshy feldspar as the existing mineral. In this way, he survived and firmly stood on the solid rock. Not only can he not be shaken by the wind, but also he has deep roots and strong leaves, and is evergreen all the year round.

geographical position

It is one of the top ten famous pines in Huangshan Mountain. It grows at 1470 meters above sea level from Beihai to qingliangtai. Its trunk is 1.5 meters long and divided into two branches. Its wings are high and low. It looks like a unicorn. It is about 500 years old.

Overview of scenic spots

Qilin pine is located at the waist of shizifeng, near Shizilin jingshe. Its diameter at breast height is 50 cm, and it is divided into two trunks at the height of 1.5 meters, which grow obliquely in the east-west direction, and the height is scattered. The high branch is like a unicorn, the low branch is like a tail, and the trunk bark is like a beetle. Hence the name. Today, there is a poem praising: "it's so divine to hold your head up and raise your tail. It's like a unicorn. The prosperity of the country is auspicious, and it forebodes the spring of all generations. "

history

Next to the stone steps in front of the back hall of Qingfeng temple on linsongshou mountain, there is a pine tree, which is recorded in Liaoyang county annals. "I'm more than 20 years old, and I'm blue and white, like a poplar. Some people call it jiesong, while the monks call it hupisong. Chinese and foreign tourists can't name it "it's said that it was planted by Liang Bannong, the forefather of Gaixiang.". In fact, this pine tree is a rare ornamental tree species, white pine tree shape tall and straight, the bark is flaky, showing a bluish white endothelium. It is very elegant, with three needles and one east leaf. It is thick, hard and glossy. The cones are egg shaped, with light on the top. It's very rare in Liaoyang. Unfortunately, in 1997, people who had just stepped out of ten years of turmoil suddenly said that the bark of Pinus bungeana could cure tracheitis, so people came in droves to peel and snatch the bark. A few years later, a man named Wang Yushan accidentally found two more seedlings in the stone gap of the back mountain. He tried his best to transplant them to the main hall of the temple. Up to now, there were small bowls of more than three meters thick and more than three meters high. His delicate appearance is very similar to that of the old trees of that year

maintenance management

There is a serious decline in the growth of Kirin pine. Through analysis, the main reasons for the decline are: bark damage caused by diseases and insect pests and mechanical damage, too thick topsoil layer formed after the implementation of diversion in Huangshan in the 1980s, stone fence seriously affected the extension of root system, at the same time, the drainage was not smooth, resulting in some water around the root, and the surrounding vegetation affected the growth of Kirin pine, especially The results showed that the main reason for the decline of P. unicorn was the root. Therefore, in addition to timely handling the damaged branches, the main reason for the decline of P. unicorn was the rapid growth of shrubs nearby. The main treatment measures are as follows:

1. Part of the treated soil is 2m, so that the original root neck is exposed again. When the soil is backfilled, the forest soil and shrub twigs are landfilled layer by layer, which not only increases the soil aeration, but also increases the organic matter. In addition, a drainage ditch is set up on the upslope of the trunk, so that the surface runoff in the upslope direction can bypass the root of Pinus elliottii.

2. Four ventilation pipes were set up vertically in the southeast of xiansong. Bamboo was used to cut through the slubs and holes were made on the wall. In addition, ventilation pipes are also set in the horizontal direction. Firstly, four horizontal ditches are excavated, 60cm in width and 70cm in depth. The ditch is backfilled with forest soil 10m in thickness, and then a layer of broken branches is laid on it. Then a bamboo ventilation pipe is set on it to connect the vertical and horizontal ventilation pipes. Finally, the original topsoil after sand mixing is laid on the surface. The above ground part was treated to remove withered branches, leaves and cones. Cotton was dipped in 50 times potassium ammonium phosphate solution to block the pores of all exposed sawflies and yellow ants. The parts of bark shedding and xylem exposed and tree holes were sealed. After the rotten part was repaired with a scraper, the mixture of Nongkang 120 diluent and callus agent (biological hormone) was used for disinfection treatment at the ratio of 25:11. Then the sealant dbxm (made by Beijing Institute of Aeronautical Materials Science) was mixed with the curing agent DR2 at the ratio of 1011. It was filled with a special injector, leaving no gap, and then smoothed, and the outer surface was decorated with bark. Remove weeds and shrubs around, clean up the surrounding environment and keep ventilation and light transmission
