Dali in autumn, the sky is high and the air is cool, the clouds are light and the wind is light, the mountains are green and green, and Erhai is as clear as a mirror, making countless tourists linger.
Gusheng Village, Wanqiao Town, Dali City, Yunnan Province is located on the Erhai Lake, "Mother Lake". The roads in the village are neat, the streams flow and the trees are shaded. The sun shines on the golden rice fields beside the village. Several harvesters are driving back and forth with all their power. The villagers bent over and took a step to ensure that all the rice should be collected.
Villager He Licheng skillfully waved his sickle, leaving behind a row of neat rice stubble. "Although we all grow rice, the current method is different from the past." This Bai ethnic group man who grew up by Erhai Lake told reporters about farming skills. "My field does not apply any fertilizer, but uses organic fertilizer. We have also done a lot of effort to protect the 'Mother Lake'!"
"If you only use organic fertilizer, no chemical fertilizer, will it affect the rice yield?"
reporter's questions attracted a burst of laughter in the fields. He Licheng stopped the sickle in his hand and said with a smile: "With organic fertilizer, not only will the rice yield not drop, but it can produce about 450 kilograms of rice per mu, but the pollution to Erhai Lake has also been reduced."
"A kilogram of rice that has obtained organic certification can be sold for more than 20 yuan per kilogram, which is several times the price before." Villager Yang Yueyuan straightened her waist and added.
On the Erhai Lake, there are many traditional agricultural villages like the Paleo Village. The villagers used chemical fertilizers to grow grain and vegetables a few years ago. The planting model of large water and fertilizers produced a large amount of farmland chokes rich in nitrogen and phosphorus, and flowed into Erhai Lake along the ditches and canals, causing pollution to the "Mother Lake".
In January 2015, General Secretary Xi Jinping emphasized during his inspection tour of Gusheng Village that the economy must develop, but it cannot be at the cost of destroying the ecological environment. Ecological and environmental protection is a long-term task and requires long-term efforts. We must protect Erhai Lake so that the natural beauty of "Cangshan is not ink and painting for thousands of years, and Erhai Lake is not stringed and qiuqin" will always stay in the world.
In order to reduce the non-point source pollution caused by nitrogen and phosphorus loss in farmland into the lake, in recent years, Dali Bai Autonomous Prefecture has promoted organic fertilizer instead of fertilizer in the Erhai Lake Basin. Villager Hei Yongqiao told reporters: "The organic fertilizer we use for farming now is all the cow dung in the surrounding villages."
Nanzhuang Village, less than 2 kilometers west of Gusheng Village, the cement roads are clean and tidy, and the white houses on both sides are arranged in an orderly manner.
"The village was not so clean before. There were cow dung piled up randomly next to the houses, rivers, and roads, which was stinking. When it rained, the rain would rush the cow dung into Erhai Lake." Li Chong, secretary of the Party Branch of Nanzhuang Village, said that the Erhai Lake basin has a tradition of raising dairy cows. The breeding scale exceeded 100,000 heads, and the manure produced by dairy cattle breeding was once one of the pollution sources of Erhai Lake.
At around 1 pm, Duan Qiaorun, a cattle breeder in the village, was cleaning up cow dung in the cattle shed, and the shoveled cow dung was successively loaded into agricultural trucks and trucks. "My family has 11 cows, and they clean them every morning, noon and evening. They fill up a car and send them to the collection station." Seeing the reporter's curiosity, Duan Qiaorun said, "You follow me to have a look."

2 kilometers away, at the Wanqiao Collection Station of Yunnan SF Erhai Environmental Protection Technology Co., Ltd., there are quite a few cattle farmers queuing up to sell cow dung. After weighing, confirming and registering, Duan Qiaorun calculated and said, "A ton of cow dung is 80 yuan, and you can earn about 1,000 yuan by selling cow dung in a month."
"Cow dung is a good thing. The collection station simply deodorizes and drys the cow dung, and then sends it to the factory to process it into organic fertilizer, which turns it into fertilizer, and reduces environmental pollution." said Yang Songxiong, the head of the collection station.
Farmers are affordable, enterprises obtain raw materials, and Erhai Lake can be managed."Only by following the path of ecological priority green development, the water of Erhai Lake will be clearer and the development of enterprises will be long-term." Zhong Shunhe, chairman of SF Express Erhai Environmental Protection Company, said that the company has built 25 organic waste collection stations in the Erhai Lake Basin. In recent years, bioengineering technology can collect and process 1.95 million tons of various wastes such as livestock and poultry manure, crop straw, etc. every year, reducing the total nitrogen and total phosphorus load into the lake.
Driven by a series of measures such as ecological relocation, mining rectification, agricultural non-point source pollution control, and over-development and construction control, pollution in the Erhai Lake basin has been effectively controlled, and the water quality of Erhai Lake has shown a positive trend. In 2020 and 2021, the water quality evaluation results of Erhai Lake were "optimized" for two consecutive years; from January to June this year, the average transparency of Erhai Lake was about 2.7 meters, the best level in the past decade.

Nowadays, the 129-kilometer-long Ecological Corridor around Erhai Lake has been fully connected. Wetlands, forests, and traditional villages are scattered on this ecological corridor like gems, becoming the new internet celebrity check-in point in Dali.
"At the foot of Cangshan Mountain, by the Erhai Lake, the rape flowers and rice grown by the villagers have also become attractions." He Qiaokun, secretary of the Party branch of Gusheng Village, said happily, "The villagers are looking forward to the successful convening of the 20th National Congress of the Communist Party of China. I believe there will definitely be more good policies to transform green waters and green mountains into gold and silver mountains."
not only Cangshan Erhai Lake , a gratifying picture of harmonious coexistence between people and nature is slowly unfolding in the Yunling land.

In 2021, the wild Asian elephant "short nose family" that crosses mountains and rivers and eats all the way has become popular at home and abroad, becoming a vivid case of Yunnan's ecological civilization construction and biodiversity protection . In addition to Asian elephants, the number of Yunnan golden monkeys has increased to about 3,800, and flagship species such as green peacock and white-eyed gibbon have also achieved stable growth.
At present, the people of all ethnic groups in Yunnan are constantly forging the concept that green waters and green mountains are gold and silver mountains, and protect the blue sky, white clouds, green waters and green mountains, and fertile land of colorful Yunnan with higher standards and stricter requirements, and strive to be the vanguard of ecological civilization construction.
