Some experts say that open burning of straw, weeds and other things in rural areas is prohibited. What do you think?

Life is endless and burning is endless!

The cost of processing straw is far higher than the profit, so burning it is natural. A day's salary for a programmer in a large factory can exceed a farmer's income from farming for a season, but the labor involved is much less. The ban on straw burning has added considerable costs to farmers.

The cost of moving from the field to an idle place is very high. The straw roots left in the fields after cutting wheat and rice are difficult to clean. The only way to clean it is by hand planing, so the benefits from planting one acre of land are not as high as the cost of cleaning up the straw roots. If it is not cleaned up, it will not rot naturally in a short period of time. When planting rice seedlings, just wait for the straw to prick your feet.

The consequence of the ban on burning straw is that the piles of straw on the fields are getting higher and higher, because after harvesting, moving straw is a very time-consuming and labor-intensive task. If it is crushed and put into the field, it will first cost more money for mechanical treatment, and then it will also affect the sowing and germination of the next season to a large extent. Wheat straw is okay, there are many plants, and it is easy to collect on a large scale. Some people collect it for free and then sell it, but there is still no good way to deal with the roots. No one wants corn stalks, so most of them are piled up and naturally rot. If it is tobacco leaves and cotton straw, it is even more difficult to use. All in all, farming is currently very hard but not profitable. If the weather is bad, you will still lose money. If this situation does not improve, technology and investment will naturally not be attracted, and farmers' subjective initiative will be greatly reduced. I hope the country can introduce effective policy guidance!

Crushing it into the field has no fertility at all, and it also affects the soil quality. It will not rot after being buried in the soil for several years.

No one has the motivation to do this, and it’s a thankless effort.

When I went home during the Spring Festival, I saw firewood piled up everywhere, including dead grass and shrubs in the ditches by the river. A train could be hidden when it drove in. The surface lacked sunlight and nutrients. It was not like this before. Someone chopped it back and burned it.

Here are a few questions

1. Is straw burning the main cause of air pollution?

Obviously not. Farmers have been burning fires for thousands of years and there is no smog. Has it become the culprit of smog in the past few years? The main cause of air pollution is industrial waste gas emissions. To cause trouble for agriculture, it is obvious that only state officials are allowed to set fires, but the people are not allowed to light lamps.

2 Can we not burn the straw?

The answer is yes. Straw itself is a high-quality raw material. It can be humified into fertilizer, compressed to make building materials, fiber can be extracted to make paper, fungi can be cultivated, etc. In many ways, it can be concentrated and burned to generate electricity. It's also possible.

But the question is why is it not fully utilized? The reason is that the cost of these measures is relatively high to implement. The premise of these utilizations is that large-scale centralized utilization can reduce costs. However, much of China's agriculture is still at the level of a small-scale farmer economy. Concentrating straw is highly efficient and low-cost, and any model cannot be profitable. It cannot last long.

3 What is the current situation in China?

The current situation is not suitable for a blanket ban on straw burning. When the prerequisite preparation work is not in place, to blame agriculture for air pollution and to ban straw burning across the board is to add the cost of environmental protection to the already low-profit traditional agriculture. ?The state should gradually implement the straw issue. On the basis of strengthening the centralization and mechanization of industrial scale, subsidize the straw recycling technology industry, and then comprehensively convert straw incineration into straw recycling after forming an efficient and complete straw recycling mechanism. use.

If you do not burn the straw but just turn it into the ground, it will cause a large number of insect eggs and weed seeds, which will affect the next year's harvest. As for environmental pollution, industrial pollution has a greater impact than burning straw, and it also lasts longer. Although it is said that "scientific utilization of straw", the promotion of work and the automated process are not good. Speaking of straw nutrients, potassium fertilizer is also extremely important in farming.
