Pofengling is home to 200,000 wild yellow oak trees, which was once known as the most spectacular yellow chestnut viewing area in North China. Behind the beautiful scenery, there is a group of "red leaf doctors" who have paid silently, and they have been volunteering to guide the scenic spot to control forest diseases and insect pests for 8 years and guard this mountain forest.

Find out the habits of 200,000 wild yellow oak trees
The Pofengling Scenic Area in Huangshandian Village, Zhoukoudian Town, Fangshan District, has 200,000 wild yellow trees, and the best viewing period for autumn leaves from the end of October to mid-November is the best time to watch the autumn leaves. Since last weekend, the Autumn Leaves Festival has been held here. On the hiking trail, there are a few "tourists" who look at the autumn leaves in a somewhat special way - others are standing in front of huangqi with their mobile phones and cameras, but these people carefully look at the entire autumn leaves, take pictures of the leaves with their cameras, and write something in the book.
They were originally experts of the Forest Fruit Science and Technology Service Center in Fangshan District, known as "Red Leaf Doctors".
The villagers of Huangshandian Village said that Pofengling can have today, and they have to give several experts a head credit. Whether it's cold or heat, experts often climb up and down the 1,700-meter-high slope peak to investigate the dynamics of pest and disease and the growth of trees.
"Huangshandian Village can have today's scenic spots, homestays, these 200,000 huangqi are indispensable, if it is really infected with disease, the golden sign can be smashed." Tian Wendong, director of the Forest Fruit Science and Technology Service Center in Fangshan District, said that because of the impact of the climate, the possibility of wild yellow oaks unattended in many places has increased, but the effort pays off, most of the 200,000 wild yellow trees in Pofengling are still red like fire, "Collect more leaves with powdery mildew, take photos, record the point, and be sure to work harder when managing in winter." Tian Wendong reminded the staff around him.
"This year, Beijing has abundant rainfall, 7 days off on National Day, and 6 days of rain in Pofengling. Too much precipitation will make HuangQi weak, if there is no help from experts, Huangqi did not wait for red, as long as the wind blows for a few days, the leaves will fall off! Zhang Jingang, secretary of the party branch of Huangshandian Village, is full of gratitude for the arrival of the "Red Leaf Doctors".
Experts have been associated with scenic spots as early as 2013. At that time, the staff of Pofengling Scenic Area found that the red leaves were not red, and the person in charge Gao Wenzhi found Tian Wendong, who immediately took the senior engineer Bai Shuming to "treat the disease" after he knew the situation, thus starting the work of volunteering to guide the prevention and control of forest diseases and insect pests, which has been 8 years now.
"The Valley of Pofengling is deep and thin, the soil is poor, and wild yellow oak is easy to get sick. It is not difficult to prevent and control powdery mildew, pruning should be scientific, let the tree grow to a high place, improve the light transmittance, the germs on the ground can not reach, clean up the stumps and so on must also keep up. Years of "diagnosis and treatment" have made Bai Shuming and his colleagues more and more aware of the habits of these 200,000 wild yellow oaks.
The experts helped Po Fengling train a professional yellow oak conservation team of more than 200 people, and also donated equipment for the prevention and control of diseases and insect pests such as electric sprays in scenic spots. Gao Wenzhi still remembers the scene of the experts in the scenic spot for the first year, "Bai Shuming pruned 30 typical yellow trees and taught everyone hand in hand." During that time, experts brought gardeners, and the branches pruned every day were spread on the ground 20 centimeters thick, and the whole tree pruning rate reached 40%.
Identify the "Hidden Master" who nibbles on HuangQi
The Pofengling Trail is 6 kilometres long and can be completed in half a day, but experts spend a full day each time they go up the mountain. "You can't go around looking at the flowers, many pests are especially hidden and camouflaged." Zhou Xiaoran, a member of the expert group, said that the 200,000 wild yellow oaks in Pofengling are large, and any insect pests cannot be ignored, if the insect pests on a tree are not killed, in a few days, a large area of yellow oak around it will suffer, and when it is serious, it will endanger the life of the tree and cause irreversible impact.
Huang Que Ti Jump armor is a kind of "hidden master" that endangers Huang Li. A few years ago, one morning in early summer, Gao Wenzhi ran into Tian Wendong's office in a hurry, "I don't know what this is, this little bug specializes in nibbling on tree buds, and the new buds can't be eaten by it, so you can help me think of a way!" Gao Wenzhi showed the photos he had taken to Tian Wendong. With his professional knowledge, Tian Wendong immediately recognized that this was Huang Li's shin jumping armor, "This insect is clever and cunning, good at camouflage, in order to escape the capture of natural enemies." In the larval stage, it disguises itself as a small lump of 'bird shit' lurking on the leaves and nibbling freely. Tian Wendong said that huang lichen jumped armor with a large amount of food, and if it was not killed in time, it could gnaw away the entire yellow oak forest. The members of the expert group worked with the gardeners for a full 5 days to control the pests, but fortunately did not affect the autumn foliage season of the year.
After the Yellow Chestnut Jumping Armor of Pofeng Ridge was controlled, the experts came to Da'an Mountain, Qinglong Lake and other places to investigate. In order to find out the occurrence of Huangli tibia jumping armor in the mainland, they also set up 10 sample plots in key areas for systematic observation, which accumulated valuable experience for the governance of Huangli tiara jumping armor. The following year, when the yellow chestnut tibia jumping nails multiplied and bred again, the horticultural workers prevented and controlled the diseases and insect pests in the forest area in an orderly manner, and the prevention and control area reached more than 20,000 mu, ensuring the safety and security of the ecological forest. At present, the Forest Fruit Science and Technology Service Center in Fangshan District has transported the experience of Pofengling in the prevention and control of powdery mildew and shin jumping nails to Bairui Valley, DaanShan and other places.
May this mountain forest be guarded all the time
More than a decade ago, PofengLing was not as beautiful as it is today. Before 2009, Huangshandian Village had long been mining and selling limestone as the main source of income, generating more than 3 million yuan of income for the village collective every year, and the opening of the mountain for many years destroyed the environment. Villagers use the burn-resistant, fragrant yellow oak as firewood to chop home, and the locals jokingly call it "Broken Ridge".
"With the development of the economy, the demand for urban people to travel to the countryside will increase, and if the mountain is made into a tourist attraction, it may attract some tourists." In 2009, the party branch of Huangshandian Village officially decided to build the Pofengling Scenic Area and closed the limestone mine the following year.
From 2009 to 2013, the Pofengling Scenic Area was built while the soft opening of free tickets. The villagers realized that 200,000 wild yellow oak plants were a fortune, and began to close the mountains and cultivate forests, which could control the diseases and insect pests of yellow oak, and had to ask professionals to help. Initially, the autumn leaves of Pofeng Ridge had a variety of diseases, because of the lack of management, the grass under the trees grew wildly more than half a person tall.
From 2013 to the present, in the past 8 years, experts from the Forest Fruit Science and Technology Service Center in Fangshan District have made Pofengling a popular spot for enjoying autumn leaves from "Broken Ridge". Huangshandian Village has also developed more than 50 boutique guesthouses such as "Grandma's House", and holidays are often "difficult to find a room". Scenic spots and homestays bring more than 20 million yuan of income to the village collective every year.
The village is getting richer and richer, but the experts of the Forest Fruit Science and Technology Service Center in Fangshan District have never taken a penny from the village, and they are all obligated to guide the prevention and control of forest diseases and insect pests. "In fact, like the yellow oak on this mountain, we have found the soil that suits us, and we are lucky to take root, sprout, flower and bear fruit here." If necessary, we are willing to guard this mountain forest and continue to do what we love! Tian Wendong said.
