"Organic pig" won the award from the United Nations

Introduction: I've long heard that Panjin has an ecological farm in Xi'an, which has raised a "global top 500 ecology" by raising pigs What do these pigs rely on to win the "grand prize" from the United Nations? Reporters have not been able to understand the reason One sunset evening, the reporter did not say hello to anyone, directly came to the farm, a foot just walked into the gate of the farm, was stopped by the staff No matter how to explain it, he was unable to get in touch with the leader of the field, so he closed the door The next day, the reporter with "insight" found the personnel of the environmental protection bureau to accompany him, and he was "summoned" by the leaders of the farm I thought I could see the "face" of the pig this time, but I was told that the whole field was carrying out epidemic prevention, so I was afraid that the outsiders would bring the disease to the "pig baby" The reporter can only "appreciate" the outside of the farm, and at the same time, he has to go back to the great land A few years later, the reporter went to Panjin to attend a meeting, in which there were arrangements to visit the farm, and finally the day came to lift the "mysterious veil" on the pig As we are already familiar with the road, we rushed to the front Seeing that we were near the pigsty, we were stopped by the staff again We were asked to put on the "white hook", put on high boots, and "watch from afar" across the fence on the spot It's the "autumn tiger" weather The sun is blazing We've been sweating profusely, but the pigs in the pigsty are taking a pleasant shower How cool! Looking around, this farm is really different: what pours into our eyes is a large area of paddy field, large green plants, cascading steel frames covered with melons and vines, on which there are fruits of different shapes, hanging red and green everywhere, as if we are in a big garden What's more attractive is the ecological circulation system here: every morning, workers use water to wash pig's feces and urine, and the fat water flows into the pond where water hyacinth and duckweed grow respectively along the underground pipeline The stinking feces and urine water is the best nourishment for the growth of water hyacinth and duckweed, while water hyacinth and duckweed are the bluefeed for pigs In this cycle, the water quality has been preliminarily purified, and then discharged into the fish pond with an annual output of 200000 Jin of fish in the farm The plankton in the water provides rich bait for fish and crab, and finally discharged into the peripheral rice field After rice absorption and soil utilization, it is reduced to clean natural water, which is then used to wash the pigsty, thus completing the ecological virtuous cycle When the reporter lamented many mysteries of the farm, the leader accompanying the tour said a surprising sentence: "now the market price of pork we produce is up to 30 yuan a kilogram! "What! Can these pigs, which look like ordinary pigs, sell at such a high price? "It's only after questioning that we know that the farm passed the certification of the National Authority last year and became the first enterprise to produce" organic pigs "in China These pigs do not use any synthetic preservatives, food additives and artificial pigments in the process of feeding, processing and packaging Their meat quality is good and the content of various harmful ingredients is far below the national standard.
