Pig farm pollution problem reappears! How do farmers avoid stepping on the "red line"

"Pollution" has always been a red line that farmers need to be highly vigilant. Once this red line is touched, no matter it pollutes residents' environment or endangers basic farmland and waters, both large groups and small farmers will inevitably usher in rectification.

In the last month of 2022, several "pig farm pollution" incidents were exposed, but the question is how farmers can really avoid pollution and keep the red line for a long time.

Reproduction of pig farm pollution According to the report of xiaoxiang morning herald on June 65438+February 65438+April, the People's Court of Nanchuan District of Chongqing tried a case that the ancestral grave was polluted due to the overflow of pig farm biogas slurry.

The case shows that the biogas slurry discharged from a pig farm leaked to Mr. Zhang's ancestral grave, which caused the biogas slurry from the pig farm to accumulate around the ancestral grave and polluted the cemetery. After the negotiation failed, Mr. Zhang sued the relevant pig farm and claimed 29,300 yuan for spiritual comfort and grave relocation. Finally, the court awarded compensation to 1 1500 yuan.

Friends in the aquaculture industry know that compared with most farms with pollution problems, the punishment of the above pig farms is not high, but it can be seen that "pollution" is always a red line no matter when and where it occurs. Once pollution happens, as long as someone sues, it is easy to lose the case and be punished.

Of course, in recent years, with the scientific control of environmental protection, grass-roots law enforcement has gradually become moderate, and there are few practices such as "forced demolition and forced sale" and "demolition once and for all".

According to Southern Metropolis Daily 12 and 14, the villagers complained that there was a pig farm in the center of the village, and the pigsty was less than 10 meter away from the private residence. The villagers could not sleep because of pig manure and urine sewage, and the drinking water source was polluted.

After the complaint, the relevant departments made an on-the-spot investigation on all farmers in Sulao village. Instead of "tearing them down" as before, they coordinated the township and village cadres, demanding the establishment of cooperatives in the form of villagers' groups, choosing places far away from the village, centralized farming, centralized sewage treatment and standardized management, so as to protect the living environment and deal with farming pollution to the maximum extent without harming farmers.

From the above two latest cases about "pig pollution", it can be clearly seen that environmental protection is still the top priority, but it will not be easily severely punished or rudely "demolished".

This is also because the documents of relevant departments have repeatedly mentioned that pig farms should not be dismantled illegally. At the same time, for large-scale pig farms that need to be dismantled, it is necessary to arrange reconstruction in different places to ensure the stable production capacity of pigs.

The combination of planting and breeding will promote the increase of income, and raising pigs will inevitably discharge feces. Many farm owners have a headache about the wastewater and feces discharged from pig farms.

But now many pig farms not only realize the full treatment of manure, but also create more income with the help of "combination of planting and breeding"

Many people think that large-scale pig farms are relatively mature, but in fact, some small-scale farmers can do well.

For example, Lin Zhenhai, a farmer in Pinghe County, Zhangzhou City, Fujian Province, has a breeding scale of only over 500 heads. However, through the effective use of pig manure, he not only ended the manure problem that had been a headache for him for nearly 65,438+00 years, but also planted a large orchard to generate income in both directions.

The surrounding villagers have always resented the excrement discharged from Lin Zhenhai's pig farm, and the green mountains and green hills are becoming smelly and dirty mountains.

Under the demand of environmental protection, Lin Zhenhai concentrated manure into biogas fertilizer, and then planted 180 mu of orchard around the farm, and irrigated the orchard with biogas fertilizer by laying a pipe network.

Therefore, these fruits with organic fertilizer grow better, sweeter and even sell better than those with chemical fertilizer.

In this way, Lin Zhenhai realized the counterattack of the pig farm by relying on the "combination of planting and breeding", and turning waste into treasure is the best way to cultivate manure.

It is understood that Zhangzhou City has deeply popularized the "combination of planting and breeding". This year, the utilization rate of livestock manure resources in the city reached 99.2%, and the matching rate of manure treatment facilities and equipment in large-scale farms reached 100%.

In fact, since ancient times, "picking manure for farming" has always been an important mode of production for farmers. However, after the popularization of modern chemical fertilizers, many people saw that the crops with chemical fertilizers grew fast and yielded a lot, so the proportion of organic fertilizers gradually decreased. But in fact, the descendants of China people have been farming for thousands of years, and the soil fertility is still guaranteed. Organic fertilizer is the biggest contributor.

It is worth noting that the harm of long-term use of chemical fertilizers has become more and more obvious. In the future, aquaculture will not only provide "organic fertilizer" for its own "environmental protection problems", but also accelerate its popularization and improve the resource utilization rate of "turning manure into fertilizer" in agricultural development.

The general trend of the combination of planting and breeding China is the country that uses the most chemical fertilizers and overuses them seriously in the world. The use of chemical fertilizers in China has long accounted for more than 30% of the world total, and the grain output accounts for about 16% of the world total. The average amount of fertilizer used per hectare is more than four times the world average!

It is precisely because of the excessive use of chemical fertilizers in China that soil properties are degraded and acidified, and even many farmers can feel that "chemical fertilizers are getting worse and worse". In previous years, the dosage of a bag of chemical fertilizer is now one and a half, which is not the reason of chemical fertilizer itself, but the decline of soil fertility caused by long-term use of chemical fertilizer.

Therefore, it will fall into a vicious circle of more and more fertilizers and worse land.

Organic fertilizer contains a lot of organic matter, nitrogen, phosphorus, potassium and trace nutrients, which is comprehensive and lasting for crops. For land, organic fertilizer contains a lot of beneficial microorganisms and humic acid, which can promote the formation of soil aggregate structure, maintain or improve soil softness, improve the "micro-ecology" of soil as a whole and realize sustainable planting and utilization.

Many people say that if organic fertilizer is so good, why is it used less and less?

On the one hand, the decrease in the use of organic fertilizer is the influence of chemical fertilizer, on the other hand, with the development of urbanization, most human feces are no longer used.

Therefore, "combination of planting and breeding" is not only an important direction of aquaculture, but also very important to the whole agriculture in China.

With the decrease of human excrement, farms have become the most important channel to provide organic fertilizer.

Therefore, the "combination of planting and breeding" of farm development is not only beneficial to itself, but also beneficial to people's livelihood.

However, there is a big problem that needs attention, that is, for many pig farms, the scale of raising pigs has increased and the discharge of feces has increased, but there are not so many orchards and vegetable fields to supply digested feces. It should be noted that the capacity of fertilizer treatment per unit area of land in unit time is limited, so farmers should consult professionals when implementing the "combination of planting and raising" to achieve the best "matching of planting and raising".

Respecting the laws of nature and maintaining ecological balance will not only promote the high-quality development of aquaculture and planting, but also benefit ourselves for a long time, not just for future generations.
