It is undeniable that China's ecological environment is gradually getting better with the efforts of the people, which is also thanks to the introduction of environmental protection policies.
For example, travel as green as possible, separate garbage and dispose of it centrally, and prohibit straw burning.
Speaking of which, straw burning has been banned in our country for several years.
But unlike that,Countries in Europe and the United States have turned a blind eye to this and still allow their own people to burn at will.
So now the question is, what is the reason why China wants to explicitly prohibit the burning of straw?
Why are those countries in Europe and the United States so different from China in this regard?Could it be that we are really like the rumors, we fell for European and American countries?
The first thing we need to understand is why farmers burn straw, and what we need to know is that in the early days, these straws were also used by villagers to make fires and cook meals.
In the past, the villagers did not have firewood at home, so they would push a small cart during the harvest and go to the field to pick up straw and pull it back for burning.
However, as time went by, every household had gas and household appliances, and the demand for straw fires dropped greatly.
The villagers don't want to spend a lot of effort to pick up firewood again, and the harvest is generally *** noon is the hot time, but there is no other way to do anything, they will not be willing to run out to let the sun shine.
Secondly, the grass ash turned into straw after burning can also be used as fertilizer in the field, so the villagers naturally want to burn it in the field. This not only saves you the time of pulling fertilizer, but also greatly reduces the cost of buying fertilizer
The last is that the cost of straw disposal by villagers is too high, and it is very difficult for the straw left in the field to play an efficient role when harvesting crops. Due to the limited development of science and technology, the feasibility of straw transformation and utilization is very low.
For example, if you want to build a biogas digester around straw, it will cost at least three or four thousand, and you should know that the income of the villagers from these acres of land is only a few thousand yuan. It is naturally unreasonable for them to come up with three or four thousand out of it.
And because the value play rate of straw is relatively low, even if they are sold to those farmers who raise cattle and pigs, the price is a few cents a pound, which is really pitiful. If it is converted, it is not enough for those manpower and material resources.
In conclusion, in the absence of hard and fast rules, straw burning is undoubtedly the most concise and efficient way for villagers. However, in terms of various environmental safety precautions and other factors, it is absolutely not feasible to burn straw.
First, it should be noted that China's ban on straw burning is not on the European and American countries, many years ago, we in China made an explicit ban on the burning of straw, and its original intention was to protect the environment. It is worth mentioning that when straw is burned, it can produce a large amount of sulfur dioxide, carbon monoxide and other gases and particulate matter that are harmful to the human body through chemical reactions.
When they are inhaled into the body, they will cause respiratory diseases in the human body with a high probability, and at the same time, they can also cause the problem of climate warming if they are inhaled into the body. Knowing that burning straw will have a positive impact on global warming, China has always been a major country in the face of this situation, so it took the lead in proposing a ban on burning straw at home.
If the straw is treated in other ways, such as composting or using bioenergy to generate electricity, the amount of harmful substances burned in it can be greatly reduced. In this way, not only can the straw become an effective fertility for the soil, but also reduce the pressure of environmental pollution, which is a way to kill two birds with one stone.
Secondly, straw is also a rare organic fertilizer, after systematic treatment, it produces carbon, nitrogen, phosphorus and other substances become rich nutrients in the soil, thereby promoting the growth of crops. In addition, straw can also slow down the impact of raindrops.
If it is covered on the ground, it also prevents the soil from being washed away, thus reducing soil erosion in the farmland. It is also important to note that once the residue from burning straw flows into the river, there is a great possibility that it will clog the river and reservoir.
It can be seen that the ban on straw burning is also conducive to the protection of water resources, and harmful substances such as ammonia nitrogen in its residue are also extremely unfavorable to water bodies. Therefore, banning straw burning is also an important part of water management.
Finally, banning the burning of straw and effectively disposing of it can also provide an effective path for sustainable agricultural development. At present, the world is facing a severe situation of resource shortage and relative scarcity, if straw is composted, it can not only reduce pollutant emissions, but also form a virtuous circle.
Not only that, straw can also be used as animal feed, providing more raw materials for related aquaculture industries, so as to greatly improve its production efficiency. In addition, if straw is used as bioenergy, it can be used to generate electricity through measures such as fermentation.
At this time, the straw can be converted into a circular energy, which is beneficial to all aspects of society. In general, for the sake of environmental water conservation, and to leave a warm home for future generations, China has issued a decree prohibiting straw burning.
But what makes people feel strange is that there are rumors that those European and American countries are not the same as China, on the contrary, they can burn straw at will in China, why is that?Is there something hidden in this?
It should be noted that European and American countries are not absolutely free about the burning of straw, although their countries allow straw burning, but there are also prerequisites. That is, straw burning is only permitted if the following circumstances or reasons are met by law.
First of all, if there is a serious insect infestation in the field that needs to be treated urgently, or if the relevant scientists have scientific needs, it is also allowed. However, before incineration, it must also be approved by the relevant departments, and only after approval can the straw be burned.
The second point is that the person who burns straw must be equipped with professional qualifications and relevant licenses, and it is important to know that if you burn straw, it will cause large-scale fires and the like. Most of the European and American countries are vast and sparsely populated, so if a fire breaks out, the consequences can be imagined.
Therefore, their countries basically require more professional people to operate, so as to avoid unnecessary troubles. Secondly, European and American countries also stipulate that straw burning must be carried out within the specified time and place, which seems to have a high pass rate, but if someone violates the relevant regulations, they will face a fine.
In addition, European and American countries have also come up with a way to deal with straw, that is, to use straw to return to the field, and there are two ways to do this. The first is that after harvesting the crops, the straw is directly put into the relevant machinery for crushing, and then in the subsequent cultivation, it can be directly sprinkled into the land.
Finally, the crushed straw decomposes and formally merges with the soil. Another way is to mix the straw with lime, manure, etc., after it is crushed, so that it can become a natural fertilizer, and then it can be sprinkled into the land to play a positive and effective role.
Finally, I have to mention that China is really a big country to the fullest, in the burning of straw, the first to set an example, it is reported that China is still studying how to turn straw into treasure in the new field. At this point, each of us should also actively respond to the environmental protection policies issued by the state.
Not for anything else, just to make your living environment better, and at the same time contribute to the sustainable development of the world!
