"No burning of straw". What's going on here?

It is forbidden to burn straw, which causes endless tears for farmers. The expert group suggested that incineration should be linked to environmental pollution; Quite a few farmers' friends, especially large contractors, don't understand!

Advantages and disadvantages of straw burning, is it an environmental hazard or a safety hazard to prohibit burning? 1, reducing the occurrence of pests and diseases. A large number of germs and eggs are parasitic on straw, and burning with fire can kill germs and eggs stored on straw. This method is the most effective and the lowest cost.

2. Reduce the number of weeds. Most weeds in traditional Chinese medicine hospitals mature and fall on the surface of cultivated land. Burning straw can clean up the seeds of most weeds, except some weeds propagated by tubers, and reduce the number of weeds in the next season.

3. Return the accumulated fertilizer to the field. The ash after straw burning contains a lot of potassium and phosphorus, which can be absorbed by the soil for crops or directly applied to the soil without decomposition.

4. Increase soil permeability. Through the high temperature of straw burning, the surface soil is heated and expanded, which improves the physical properties of the surface soil and increases the permeability of the soil.

Then why didn't burning straw have such a big impact in the past? 1. In the past, the breeding level was underdeveloped, and most of the varieties planted were local varieties, with low yield and low density. In the past, farmers used straw as fuel and livestock feed, and only burned inexhaustible straw, which means that the amount of straw burned was very small.

2. Before farming, there was not much slash-and-burn without the intervention of agricultural machinery. Most of them are cultivated by human or animal power, but the efficiency is limited. Cultivated land is far less than it is now, and there is not so much straw burned.

What are the advantages and disadvantages of burning and banning burning?

In winter, the temperature is low and the time is long, and the straw is not easy to rot, which affects the normal agricultural production. As for the benefits of returning straw to the field, I really want to say that those experts will know the pros and cons after planting it for two years.

Since incineration is not allowed, the treatment of straw must be put on the agenda. Whether returning farmland, breaking ground or bundling, the efficiency is lower than burning, which easily affects the cultivation time of the next crop of grain.

Straw returning to the field needs crushing, stubble breaking and deep turning, and urea needs to be added to promote its rapid decay, which increases the production cost; It costs money to bundle or package and transport it to other places. No matter how it is handled, it seems that as long as it is not burned, the cost will always increase.

The hazards of burning straw include polluting the air, causing uncontrollable fires, affecting traffic and threatening the safety of people's lives and property, especially burning straw near villages. Once a fire breaks out, the consequences are unimaginable, and more is a safety issue. For the sake of the beautiful scenery of the home, it seems an imperative choice to prohibit burning straw in the open air.

Thousands of years of slash and burn, burning wasteland and accumulating fertilizer, although unnecessary, have become pollution! Didn't organic matter return to the soil? We should proceed from reality and fundamentally solve the problem. The government should come up with a solution to the problem, how to deal with the straw and how to recycle it. The state should guide farmers to use straw, instead of making a one-size-fits-all approach under the premise of imperfect straw treatment and increasing farmers' pressure.
