After "straw burning" was banned in rural areas, another "reversal" occurred? Why can it burn again now?

Things involving agriculture are always a top priority, and the measures and methods for dealing with straw have always been a matter of great concern to people.

Although straw burning was banned on a large scale in rural areas in the past few years, in recent years, there has been new discussion on relaxing restrictions on straw burning.

The historical background of this matter is still relatively complicated, and what we have to do is to clarify the causes and consequences. The internal logical relationship is the goal that needs to be explored. Straw burning:? Sudden ban due to the trend of the times

Not only burning straw, many agricultural products left over from the previous season with no economic value will be returned again through burning as long as they can be burned into the fields. This is a realistic portrayal of China’s agricultural civilization for thousands of years.

But as time gradually enters modern times, large-scale industrialization—especially the environmental pollution problems caused by heavy industrial production—has made people pay particular attention to environmental issues in production and life.

Coupled with the smog issue that has attracted much attention in previous years, discussions about environmental governance plans and solutions once made headlines.

Under this trend of public opinion, people naturally turn their attention to straw burning, which will also cause certain environmental pollution.

So starting around 2010, various regions have successively banned large-scale straw burning activities in agricultural production.

Straw burning was originally intended to fully convert the remaining abandoned crops into nutrients, but it was stopped due to public opinion of the times and actual problems.

In the following years, the four words "straw burning" gradually faded out of people's sight, as if this method of burning had already existed in historical memory and no one mentioned it.

But no one expected that in recent years, the topic of straw burning would once again be brought up by the public, and this time it was not banned but restored, and a considerable number of people even supported and advocated it.

What is the secret behind this? The author will take everyone to analyze it slowly. Hidden story: The economic and social reality after the ban on straw burning

The reason why measures to ban straw burning were promoted on a large scale in various places was, on the one hand, due to environmental considerations.

On the other hand, it is also because many experts and scholars have proposed that crushing straw, covering the ground surface, and naturally decaying can effectively improve soil fertility. At least from the actual effect, it is no better than burning. Difference.

In addition, in order to obtain a more effective response, many local governments have used financial subsidies to call on farmers to abandon burning straw and work in the form of crushing and covering.

In the beginning, it was true that the vast majority of farmers gave up burning straw, but as time went by, many farmers found that the benefits of directly crushing straw to cover the ground surface were not obvious. In some places, even the increase in crop income due to the use of this method is not obvious.

Suddenly, this problem became serious. As for why it is unfavorable to increase crop income, this is because if unburned straw is crushed and sprinkled directly into the rice fields, the straw will undergo a natural decay and fermentation process. In this process, the straw itself needs to absorb energy.

Coincidentally, when the straw is rotting and fermenting naturally, the crops in the farmland are basically still in their infancy, and many crops have just sprouted short seedlings. At this time, they are in urgent need of light and nutrient supplements.

However, large accumulations of straw will compete with crops and absorb nutrients, so that they can ferment and release energy; on the other hand, in many areas, due to improper use of straw by farmers, large amounts of straw accumulate. In this way, during the initial transplanting or sowing stage, the seeds or seedlings are likely to be blocked by the straw and unable to smoothly integrate with the soil.

The unfermented straw itself cannot provide nutrients for the seeds, which ultimately leads to the inability to increase or even reduce the yield of crops.

Burn ban remains: Do you support this decision?

But no matter what, the relevant departments in various places have continued to burn straw as a basic agricultural policy to this day, and there must be factors to consider.

Although there are indeed some problems with directly crushing and mulching straw, as long as management and cultivation are carried out through scientific means, coupled with positive guidance to farmers, the crushing and mulching method does have certain benefits. positive meaning.

At least for now, the continued ban on straw burning is a foreseeable result.

It’s just that behind the ban, how to guide farmers in scientific and large-scale agricultural production and increase crop yields to new highs is an issue that needs to be actively considered and explored everywhere.

At least in the author’s opinion, straw burning does have advantages and disadvantages. But from a comprehensive perspective of modernization, the disadvantages do account for a large proportion, but I don’t know what readers think?
