The "green relay" of Saihanba (Chinese miracle of ecological governance ⑥)
Vehicles circled around the mountain, and the orderly order of Pinus sylvestris and larch trees outside the window appeared alternately. If it wasn’t for every passing vehicle, the ranger would raise a yellow fire flag as a warning. This dense forest of Linhai seemed to be filled with only green eyes.
Saihanba Mechanical Forest Farm, located in Weichang Manchu and Mongolian Autonomous County, Chengde City, Hebei Province, has the largest plantation forest in the world. If calculated according to the plant spacing of 1 meter, the trees in Saihanba can circle the earth's equator for 12 weeks.
Facing this vast forest of 1.12 million acres, the reporter kept flashing a question: Are the trees in Saihanba really planted by hand?
"No need to doubt. Many tourists have doubts like you. As the first agent of Saihanba, I can say responsibly that this piece of forest is completely artificial, and the tree of Saihanba is one of us. One is planted." The answer to the reporter's question is that this year's 76-year-old Chen Yanxian is one of the protagonists of the "six girls on the dam" story that has spread widely on Saihanba.
In the 1950s and 1960s, Beijing City always seemed to be accompanied by sand and soil. 180 kilometers north of Beijing is the Hunshandake Sandy Land with an average elevation of more than 1,000 meters. The north wind is driving straight in, carrying a large amount of dust and sand. Someone once said figuratively: If the source of sand closest to Beijing cannot be blocked, it is equivalent to standing on the roof and raising sand to the courtyard.
In 1962, Saihanba Mechanical Forest Farm was formally established. Hearing that Saihanba afforestation requires manpower, in response to the great call for "greening the motherland", Chen Yanxian, who was studying in high school in Chengde, discussed with the five sisters in the dormitory and decided to abandon the college entrance examination and go to the forest farm with his backing up. In 1963, "six girls went to the dam", this is 40 years.
One wind a year, from the beginning to the end of the year. This is a true portrayal of Saihanba at the beginning of the construction. At the beginning of afforestation, there were many difficulties. In 1962 and 1963, the survival rate of Saihanba afforestation was less than 8%. The Saihanba people quickly found the cause of the failure: the seedlings in the field were "unacceptable"; in order to succeed in afforestation, they must raise their own seedlings.
But raising seedlings is not easy, and every work procedure has strict technical requirements for land preparation, bed preparation, germination, and seeding. In order to master the compaction degree of the cover soil during sowing, Chen Yanxian and his colleagues practiced with a roller barrel over and over again. The blood bubbles were rubbed out in their hands and their arms could not be lifted up. until.
The temperature in Saihanba is extremely low in the early morning. In order to germinate the tree species, Saihanba artificially set up "Kang" for the seedlings. The germination has fixed requirements on temperature and humidity, and the nursery must always increase or decrease the firewood according to the changes. "Dense smoke always sheds tears. When people go outside, the tears will form ice particles and hang on the face, which is very uncomfortable." But even so, Chen Yanxian is accustomed to working in the nursery for more than ten hours a day.
"What are you most afraid of raising seedlings?" The reporter asked.
"I'm most afraid of seeing clouds floating!" Why? The weather in Saihanba is very cold. Once the clouds come, it means that heavy rain and hail are also inseparable, and this is the most fear of encountering nursery beds. "At that time, as soon as we saw the clouds coming, all of us threw away the work in our hands as if we heard the'command', and ran to the nursery as soon as possible, taking the grass curtains or taking off the clothes and covering the bed. "Chen Yanxian said.
With the spirit of hard work and hardship, during the 20 years since the establishment of the site from 1962 to 1982, the Saihanba people planted a total of 960,000 acres on this sandy wasteland, a total of more than 320 million plants, a million acres Lin Hai's initial exposure.
Tree planting and afforestation pay attention to "three-point afforestation, seven-point management". After 1983, the large-scale afforestation of Saihanba has basically ended. The management and management of this hard-won forest is a historical mission carried by the second-generation Saihanba people.
"I came to work in Saihanba in 1994. On the day of check-in, I looked down from the mountain. The feeling of looking at the sea of trees was really shocking." Chen Zhiqing, the director of the Saihanba Machinery Forest Farm, said that he was more convinced by Saihan The guardian spirit of the Ba people.
Soon after arriving in Saihanba, Chen Zhiqing was arranged to work in the camping area in the deep mountain of Saihanba. It is said that it is a camp forest area. In fact, only he is stationed with a forest ranger named Luo Fuxiang. What to do if there is no water? Plan a pit in the ground, irrigate some water and water, and wait for the sand to filter for one night before drinking. How to do heating? Put a sock on the ground half above the ground and burn two braziers to keep warm. Although it can't be frozen, there is a smell of smoke all over him.
Luo Fuxiang patrols the mountains every night. "He can walk twenty or thirty kilometers a day. I inspected this larch forest area today, and I walked that birch woodland tomorrow. This is not the case every day. At that time, I really felt incredible." Although only staying in the camp forest area One year, but that experience made Chen Zhiqing understand the Saihanba spirit for the first time.
In 2017, General Secretary Xi Jinping gave important instructions to the moving deeds of the builders of Saihanba Forest Farm, praising the builders of Saihanba Forest Farm for creating the human miracle of the wilderness turning into the sea of forests, and forging Saihan with mission, hard work and green development in mind Dam spirit. This made Saihanba deeply encouraged, "I will never forget that kind of pride and glory." Song Weiji, a worker at Saihanba Machinery Forest Farm, told reporters.
The general secretary's instructions made Ma Mingyue, a girl from the "post-95s" far away in Hainan, concerned about Saihanba. Ma Mingyue, who majored in gardening and design at Hainan University, has been fond of forestry since she was a child. After reading a lot of information about Saihan Dam, this little girl who looks like Wen Crepe believes that the dam is her battlefield for achieving her ideal.
In November 2019, through numerous screenings, Ma Mingyue became the third generation of Saihanba forestry people. Don't look at just a little girl in her early 20s, but she has the hard work to lose her predecessors. "Making standard plots, measuring tree spacing, and collecting disease and insect specimens, she is no slower than our boys." Liu Taiyu, who was assigned to the third township branch, told reporters.
"Although there are very few people coming to the grass-roots camping area, this way I have more time to learn business. Recently, I have summarized a new method of measuring the tree fence." She said while gesturing with the reporter, her face hanging Excited look.
It is generation after generation of "green relay" that changed Saihanba. From 1962 to 2019, the frost-free period of Saihanba increased from 52 days to 64 days, and the average annual windy days decreased from 83 days to 53 days. In December 2017, Saihanba was awarded the "Guardian of the Earth" award by the United Nations Environment Programme. This "China Green", which embodies the efforts of three generations of builders, successfully entered the world stage.
Now, looking at the thousands of acres of forest outside the office window, Chen Zhiqing is confident: "We are actively carrying out many industrial projects such as green seedlings, forest tourism, carbon sinks. With the care and encouragement of the general secretary, our "eco banner" Carry it harder!"
