Agricultural packaging waste becomes a "bomb" of farmland pollution

After the cold, the farmland in the southern mountainous area was silent.
Looking around, there was no shelter from the green grass and green rice.
The pollution of agricultural materials and packaging waste accumulated over the years of production was shocking.
In the ditch, pesticide bottles were scattered in disorder, and unburned plastic seedling trays were piled up at random by the ridge.
The strong wind blew up, and a small pile of herbicide bags were rolled into the sky, and a strange smell floated in the air.
"A large grain-growing county uses tens of millions of seedling trays and millions of pesticide bottle bags every year.
Many of them are thrown on the fields and become pollution'bombs'! Although the new pollution has come again, the economic account is beautiful, but during the reporter's interview, many grassroots cadres and farmers also calculated an environmental account.
They reflect that with the increase in the types of agricultural materials and the increase in the amount of agricultural materials used, the packaging waste of agricultural materials is also increasing sharply, causing serious pollution problems and causing further damage to the already fragile farmland ecosystem.
Although the pollution of pesticide packaging is an old problem, it is still alarming.
The agricultural cadres of many large grain-growing counties in the south have calculated a detailed account: Generally speaking, the annual grain sown area in a single grain-producing county is about 1 million mu.
According to the traditional medicine practice of farmers in the south, each mu field is used every season.
At least about 3 bottles (bags) of various types of pesticides are used.
Therefore, there are as many as 3 million waste pesticide bottles and bags produced in a year.
If this account is expanded to a province or even the whole country, the result is worrying.
As the "new army" of agricultural materials, the pollution caused by seedling trays is hidden and huge.
Several large grain growers told reporters that it is conservatively estimated that 50 seedling trays will be used for one acre of field.
Considering the popularity of seedling trays, double-season rice and other factors, a single large grain producing county uses no less than 12 million seedling trays a year.
A.
In addition, each seedling tray can generally be used continuously for two years.
Therefore, as many as 6 million seedling trays are discarded every year in a large grain production county.
Many agricultural cadres report that once the seedling trays that have been used for two years are no longer of use, many of them are discarded in the field and rarely recycled.
Some environmentalists have done sample surveys in Dongting Lake area and other places.
They found that when handling pesticide packaging bottles or bags, about 90% of farmers would choose to discard them in fields such as ridges, canals, and small rivers.
Only a small number of people would.
Bring them back to the village for incineration and other related treatments.
Many agricultural science and technology personnel told reporters that these agricultural wastes are difficult to degrade naturally in the field, and it is very difficult to deal with them.
Peng Sanhua, a grain grower in Xiangtan City, told reporters that the seedling trays are made of recycled plastic and are difficult to ignite, and they have to be burned with diesel oil.
"It burns with thick black smoke, smells bad, and pollutes the air.
" According to calculations by several grassroots agricultural cadres, the weight of a seedling tray is about 50 grams, and the total number of seedling trays discarded by a large grain county every year It weighs 300,000 kilograms, or 300 tons, which is equivalent to 5 train wagons.
These agricultural wastes discarded in fields or water ditches have caused a large amount of nitrogen, phosphorus, pesticides, heavy metals and other substances to be taken into the water body, infiltrated into the soil, and the accumulation of pollution has caused serious harm to the ecological environment.
Difficulty in recycling How to rebuild? In a public meeting, a deputy minister of the Ministry of Agriculture once stated that agriculture has surpassed industry to become my country's largest non-point source pollution industry.
The reporter investigates at the grass-roots level, and nowadays, agricultural wastes scattered in farmland, land, rivers, ponds, etc.
constitute countless large and small pollution sources.
The distribution is widespread and random, and belongs to typical agricultural non-point source pollution.
In 2015, the Ministry of Environmental Protection issued the "Administrative Measures for the Recycling and Disposal of Pesticide Packaging Waste (Trial)" (draft for comments), which clearly stated the division of responsibilities, punishment measures, and recycling system construction for pesticide packaging waste.
For example, it puts forward the recycling and treatment of pesticide packaging waste, and adheres to the principle of who produces who is responsible, who sells who recycles, and who uses who returns; pesticide manufacturers (including pesticide import companies) are responsible for the recycling and treatment of their pesticide product packaging waste; Pesticide distributors are responsible for the collection and temporary storage of the packaging waste of pesticides sold; pesticide users should return the pesticide packaging waste to the distributor in a timely manner, and shall not discard them at will.
However, many cadres and the masses still have doubts about whether these policies can be implemented at the grassroots level.
The reporter found in previous interviews that in some "beautiful villages" and pilot villages where urban and rural sanitation was built, the recycling of agricultural materials and waste had already been explored, but many problems were encountered.
These pilot villages have thought of many ways, but it is still difficult to mobilize the masses to take the initiative to participate in recycling.
A cadre told reporters, "The common people don’t lack that little money now, and they feel that it’s picking up rubbish and lose face!" In some pilot villages, due to the pressure of higher-level assessments, they even became "village cadres come to collect rubbish and pick them up in the field.
" Garbage” caused village cadres to complain.
A person in charge of the Hunan Provincial Agriculture Department told reporters that many years ago, the rural renewable resource recycling system was relatively sound.
The renewable resource recycling enterprises of the supply and marketing cooperatives were able to operate normally, and farmers were also willing to accumulate pesticide bottles to exchange for some pocket money.
However, this recycling system has become a "zombie" in many places, and many companies have even stopped operating completely.
Now it is extremely difficult to rebuild.
At the same time, the rural society has undergone major changes.
The mentality of most farmers is very different.
They are unwilling to spend a little bit of money, picking up pesticide bottles, etc.
How to encourage and urge them to participate in recycling, we still need to work together to explore the actual situation.
Effective solution.
