Pig boss dug gold in his dung and sold millions in two years.

The blue body, with a huge white oval tank, looks at first glance like a professional oil carrier-"it's full of pig dung." Zhao Ping said.

In the early morning of September 7, Zhao Ping's 20 "pig dung trucks" set out to collect manure from major farms in Qionglai, Chengdu, Sichuan Province. After treatment, the collected feces are sprinkled into the farmland and become the best farm manure. "during the busy farming season, the density of pig dung cars running back and forth is higher than that of buses." Zhao Ping said that there are more than 150 such "pig dung cars" in Qionglai.

Zhao Ping, who used to be a professional farmer, is now in charge of Jiehuan livestock manure collection service professional cooperative in Qionglai City. Two years ago, Qionglai, a major county where pigs were transferred from the country, was faced with serious non-point source pollution. Under the pressure of environmental protection, Qionglai tried to "recycle" the comprehensive utilization of livestock and poultry manure, and walked out a new mode of green development.

Aim at the "dung extraction team"

Zuo Dongliang, a pig breeder in Heishi Village, Guyi Town, raised more than 50 fattening pigs. In the past, how to deal with pig manure has always been a headache for him. "according to the fact that a pig produces 10 jin of manure every day, it produces more than 500 jin of pig manure every day, and the manure tank is full in a few days." In desperation, Zuo Dongliang had to secretly discharge his feces into the fields and river ditches, and the stink made the villagers often point to his nose and scold him.

This is not Zuo Dongliang's trouble alone. As a major national pig county, the scale of pig farming in Qionglai is about 1.4 million head a year, which produces 1.51 million tons of pig manure a year according to the output of 1.08t manure per pig. It is urgent to control non-point source pollution. "I've thought about shutting down some farms before, but where can I close them?" Ren Zhi, head of the Agricultural Construction Section of the Qionglai Municipal Bureau of Agriculture and Forestry, said that by 2014, the city's thinking had changed: to find a way out for 1.51 million tons of pig manure.

The way out is not difficult to find: as a major agricultural county, Qionglai has an annual grain sown area of more than 600,000 mu and oil sown area of more than 200,000 mu. There are also advantageous industries such as tea, fruits and vegetables, and traditional Chinese medicine. Pig manure is undoubtedly the best farm manure that this land craves.

But how to make the pig manure scattered in various farms go where it should go?

Since 2014, Qionglai has launched a special treatment of breeding pollution to explore the comprehensive utilization of livestock and poultry manure. First of all, the construction of septic storage tanks will be set as a compulsory measure, while special measures will be introduced to subsidize the construction of septic storage tanks according to the standard of 80 yuan per cubic meter. Second, to let pig dung really set foot on the "field" road, they set their sights on the local "dung extraction team" that already existed.

In that year, Qionglai decided to guide the establishment of a professional dung extraction team. The subsidy for the purchase of dung pumping equipment is very strong: manure storage tanks, electric pumps, dung storage bags and generators are all fully subsidized, with a maximum subsidy of 20,000 yuan. "it's worth it." At that time, Zhao Ping decided to join the team.

Pig manure is not enough.

Zhao Ping also has a farm at home, with a breeding scale of about 500 heads. The original intention of buying a dung truck was to solve the problem of 3 tons of pig manure per day.

"I didn't expect that the car was bought soon, and business came." Zhao Ping said: at that time, the town needed soil fertility for homestead reclamation, covering an area of more than 6000 mu. According to the amount of 3 cubic meters of manure per mu, Zhao Ping could not "eat" the deal anyway.

"the only way to eat this' steamed bun'is to expand the scale and set up co-operatives." Zhao Ping said. Over the past two years, with the expansion of business scale, the number of "pig dung cars" owned by cooperatives has increased from 3 to 20.

"this is a typical market-driven and interest-oriented." Ren Zhi said.

Now, Zhao Ping can really dig up gold from pig dung: during the busy agricultural season, each car runs six or seven times a day, and each car can hold 6.5 cubic meters of pig manure. According to the mode of operation, Zhao Ping goes to the door to collect feces, and neither side charges a fee, while for growers to irrigate the land, a fee of 30 yuan per cubic meter is charged. "so far, we have sold 30,000 cubic meters of pig manure, with a turnover of more than one million yuan."

It can be said that at present, pig manure fertilization has covered 50% of the planting area of ran Yi town. " The data given by Zhao Ping has been circumstantial by Ren Zhi: according to incomplete statistics, since the comprehensive utilization of livestock and poultry manure project, Qionglai has used 300000 cubic meters of pig manure.

However, for growers, the cost of using farm manure is higher than that of chemical fertilizer, and to really recycle pig manure, we cannot rely solely on the "heat" of Zhao Ping. To this end, Qionglai specially introduced a subsidy program to subsidize farmers who use manure on a large scale, "according to the standard of 8 yuan per cubic meter." Ren Zhi said that with subsidies for dung storage tanks and "pig dung trucks", Qionglai has integrated financial funds of more than 20 million yuan and leveraged social investment of 24 million yuan over the past two years.

Zhao Ping uses another method to attract growers. "the land irrigated by farm manure is completely different from the application of chemical fertilizer. after many years, the land with pig manure will become more and more fertile."

Recently, Zhao Ping felt that pig manure was obviously not enough, and the radius of dung collection gradually expanded to 30 kilometers away. "I have been an owner of 11 households this year, involving 17000 mu of land. how big do you say it is?"
