If straw is allowed to burn, how many pesticides and fertilizers can be reduced?

Allowing burning straw can certainly reduce pesticides and fertilizers, but it is very limited. Because burning straw mainly produces phosphorus and potassium fertilizer, the amount is not large, but its significance is to reduce pests and diseases, reduce pollution and promote environmental protection.

Did you hear me right? It reduces pollution and strengthens environmental protection. Didn't experts say that burning straw aggravated air pollution? The expert didn't say anything wrong, but did something wrong.

Because burning straw is forbidden and there is no way to solve it, fields, ditches and streams are full of straw. It has been raining for a long time, and it stinks. I don't know how to deal with it year after year, and I haven't seen any experts come out to give directions.

I really believe in experts. I am looking for experts in the countryside. The more professional, the more fake. Some experts cook with burning straw, and some experts go deep into rural life. When they live among books every day, they are not much better than Ma Su in the Three Kingdoms.

China has thousands of years of farming civilization. Straw has been burned for thousands of years, but the air has been polluted in recent years. It's just that the countryside is a soft persimmon, and the city gives some gray income. In addition, the NPC needs a proposal to control the air, taking farmers as an example.

It is suggested that the reasonable planning of straw burning should first ensure that the straw is dry, and when the weather is good, the administrative village should arrange straw burning in a planned way to reduce the generation of smoke. As for the smoke produced by straw, it can be naturally dissolved. For example, some developed countries in the United States burn straw. Facts have proved that the pollution caused by burning straw in a short time is completely acceptable through reasonable arrangement. However, it should not be burned blindly. One is that wet straw will cause pollution, and the other is that it will cause potential safety hazards.

Welcome to discuss!

Burning soil and fertilizer is the attribute of traditional agricultural production. Fire can burn the earth's soil into a bumper harvest, even if it is planted. Smoke can kill insects and kill bacteria, and it is carbon dioxide that plants need. The cost of a match, 10,000 mu of straw can be turned into 10,000 mu of gray fertilizer, and one mu of plant ash is equivalent to a generation of fertilizer. It is also a soil insecticide and fungicide. This kind of original ecological fertilizer can't be made by manpower.

The use of burning smoke can achieve the efficacy of disinfection and sterilization, mainly killing ten thousand kinds of viruses, flies and mosquitoes, and eggs are more afraid of burning smoke from straw. Straw burning in spring and autumn played the role of successive generations of flies and mosquitoes, greatly reducing virus infection. This method of using nature to control nature involves more than 10,000 tons of pesticides and 100 million tons of fertilizers. The cost of masks can be saved nationwide. If it is bad for nature and weak for agriculture, can farmers burn it?

If straw is allowed to burn, how many pesticides and fertilizers can be reduced? /kloc-in the past 0/0 years, the national environmental protection department and the provincial people's governments have issued laws and regulations prohibiting the burning of crop straws in rural areas, and also issued a punishment system. The slogan "Burning straw will be severely punished" is posted everywhere. Those who seriously pollute the environment will be fined from 500 yuan to more than 2,500 yuan, and legal responsibilities will be investigated according to law. Every rape and wheat harvest season, propaganda vehicles run everywhere, village cadres look everywhere, and farmers are forbidden to burn straw. Many of them have introduced a subsidy policy of returning straws to the fields at a price of 30-50 yuan per mu. Farmers have no choice but to return the crop straw to the field for a short time, so that the straw will not rot when planting the next crop, and it can also spread germs and reduce crop yield.

Over the years, many experts have blamed farmers for environmental pollution. Is there no pollution in the exhaust from chemical plants and cars in the city? Farmers burn crop straws in the autumn harvest season in June, and the long-term tail gas of urban chemical plants causes pollution.

Not long ago, the Ministry of Environmental Protection and other ministries and commissions conducted an investigation on the spread of germs by returning farmers' straw to the field, which led to the decline of crop production quality. In the summer of 2020, farmers can burn straw within the specified time without fines, and new policies and regulations will be introduced in various provinces and cities. Farmers can burn agricultural straws in batches in designated areas at a unified time, and farmers will no longer be embarrassed to treat crop straws for farming. Burning crop straw into organic potash fertilizer can also kill underground pests, cultivate land for farmers, reduce the expenditure on chemical fertilizers and agricultural materials, and increase farmers' income and save costs. What do you think of this? Welcome to leave a message! Straw burning can definitely say that it can kill some pests on crops and all eggs nesting on straws, so that crops are free of pests and pesticides are reduced. Straw ash can make the soil not harden, which is convenient for crops to take root, and crops can grow quickly and well, thus increasing the yield. This is the practical experience of big brother farmers, and it is also an indisputable fact.

I'm glad to answer your question.

As an agricultural technician, I would like to talk about my views on returning straw to the field.

1) Benefits of straw returning to field. As an agricultural technician, I have traveled all over the country and have a deep understanding of the soil in each place. Take Shanxi as an example. From south to north, the soil is barren and the content of soil organic matter is extremely low. Very few can reach 1%, accounting for 10% of the soil I have tested. Shanxi alkaline soil is short of organic matter, the absorption and utilization rate of mineral fertilizer is very low, the species and quantity of microorganisms in the soil drop sharply, and growers fall into the strange circle of fertilizer-barren-fertilizer input. Straw is the most common source of organic matter in the north, and returning straw to the field does increase soil organic matter and soil tillage depth.

2) The way of returning straw to field needs to be improved. In recent years, there have been many problems such as poor spring seedling rate of wheat, more and more root rot of corn and wheat, and the accumulation of underground pests of cutworms for years. Most of these are improper treatment when straw is returned to the field. In the north, the autumn temperature is low, there is little rain, and there is not enough time for corn stalks to warp in autumn, so wheat sowing is easy to stop, the emergence rate is low, and it is easy to get sick.

3) Burning straw can reduce the use of some pesticides, such as seed dressing drugs for wheat and corn, or pesticides and fungicides used later. However, burning straw can not reduce the use of chemical fertilizers, and even increase the use of chemical fertilizers.

Since ancient times, straw burning has brought limited convenience to traditional agricultural production, but it is not necessary in science.

Although the country strictly implements the policy of straw burning ban, in recent years, places like Heilongjiang have relaxed the way of burning stubble crops such as corn and sorghum in the field according to the actual situation. Therefore, many people fully support the burning of straw, especially the statement that burning straw can reduce the amount of pesticides and fertilizers in the title has been recognized.

Straw and field crop residues are the intermediate hosts for the spread of various diseases and pests to the next crop. For example, many pests lay eggs in crop residues, which can be brought to the next crop production cycle through straw and field residues to hatch. Various pathogenic fungi or bacterial spores that cause plant diseases can also be parasitic in crop residues, so the straw and crop residues left behind may be toxic, which provides convenience for the spread of diseases.

Throughout history, slash-and-burn in agriculture is an important way to cut off the spread of pests and diseases, and burning straw does have certain significance.

However, after straw burning, unburned inorganic salts in the ash remain in the soil. For example, applying plant ash to supplement soil potassium fertilizer is the principle. Therefore, straw burning can bring a certain amount of inorganic salts such as potassium to the soil, which has certain fertilizer efficiency.

However, compared with the release of a large amount of carbon dioxide and dust into the air by straw burning, the above two aspects may be insignificant. At present, the biggest crisis on the earth is the greenhouse effect, and the culprit is the emission of carbon dioxide! Of course, the direction of carbon dioxide emissions is not only straw burning, but also automobile exhaust and industrial emissions, so some people say that since we want to contribute to slowing down the greenhouse effect, we must ban all these large carbon dioxide emitters, instead of just looking for our weak agricultural fields! Speaking of which, as we all know, human activities can't stop in the two directions of automobile and industry at once, and it takes time to change its emission impact. For example, new energy vehicles are replacing gasoline and diesel vehicles, and the types of industrial energy are also undergoing great changes. On the contrary, straw burning in agriculture can be changed through scientific argumentation.

Straw burning loses a lot of organic matter, which will affect soil fertility for a long time.

The understanding of supplementing soil fertility through straw burning is actually one-sided. Straw is the residue of plants, and its composition is more organic than inorganic. In order to maintain healthy fertility, soil needs not only inorganic elements such as potassium, but also more organic elements such as nitrogen. For a long time, chemical fertilizer has been widely used in agricultural production, which not only supplements inorganic components such as potassium, but also supplements more organic components such as nitrogen.

More and more agricultural scientists have noticed the harm of applying a large amount of chemical fertilizer. Through research, it is found that long-term application of chemical fertilizer to soil has brought about side effects such as soil acidification and hardening, which has greatly damaged soil fertility, and the ability of applying chemical fertilizer to ensure food production is becoming less and less!

The way to ensure the sustainability of soil fertility is to let the soil obtain organic fertilizer according to the natural law. For thousands of years, it is not slash-and-burn that ensures the sustainable development of agriculture, but dust returns to dust and soil returns to soil, so that plants growing on the land can remain naturally decayed and return to the soil, substances including mineral elements can return to the land, and the soil can ensure sustainable productivity.

This is also the essential reason for advocating the application of organic fertilizer and resolutely reducing the use of chemical fertilizer. The direction of obtaining fertility through straw burning is to see only trees but not forests.

The appearance of new technology has brought the possibility for the deep utilization of straw.

At present, the utilization rate of straw is generally not high, and the utilization cost is high, which has the potential harm of spreading pests and diseases. This situation is expected to be changed by microbial technology. According to the information given by microbial research institutions, it is found that biological bacteria more complex than simple yeast can act on crop straw more comprehensively, and high molecular substances such as lignin can be degraded into small molecular substances in a short time under the catalysis of biological bacteria and activated enzymes, so as to soften and rot straw faster and become efficient organic fertilizer. At the same time, the current complex bacteria biotechnology can kill viruses and eggs on the treated straw, making the goal of slash-and-burn cultivation have existed since ancient times.

As long as this technology is more mature and the application cost is lower, it can fully realize the deep utilization of crop straw, and also provide guarantee for sustainable agricultural production and healthy soil cultivation.

However, this technology may still be in the laboratory stage, and it will take time to really enter the vast rural areas. This is why, after the country strongly banned the burning of straw, Heilongjiang and other provinces still loosened the ban on burning high-stubble crops according to the actual situation, which humanized eased the dilemma of dry crop production in Northeast China.

It will reduce chemical fertilizers and pesticides, but I don't think anyone can say for sure.

The state can designate local government leaders to reasonably burn straw and observe the air changes when burning straw. If it can, it will put out the fire immediately when it sees pollution. Conducive to the dispersed combustion of air at different times. Choose to burn in rainy days and see the air reaction. In my childhood memory, it seems that burning straw in rainy days is not as big as smoking in sunny days.

I can analyze this problem like this. If the orange stalks are allowed to be burned, the amount of chemical fertilizer will not be much reduced, while the amount of pesticides may be reduced by about 30%, because many eggs are parasitic on the orange stalks of crops all winter. If the orange stalks are burned, many eggs will be burned together, and pests will be reduced in the coming year. Therefore, the reduction of pests will reduce the use of pesticides, reduce the workload of farmers and bring health to crop consumers.

From a farmer's point of view, the biggest harm of burning straw is that the safety hazard is too great and it is easy to cause fire, because wheat harvest is usually in a high temperature and dry climate. On the one hand, wheat is fully mature, and as long as there is Mars, it can cause fires, with many southerly winds, hot and dry. In those days when wheat was harvested, even the blowing wind was hot. As long as there is fire, it is difficult to put out the fire.

Aside from safety hazards, I personally think that burning straw has many benefits. After all, the statement of environmental pollution is not clear, and there are too many pollution sources. If you say that burning straw leads to environmental degradation, then the crime is too big to be worthy of the name and farmers can't afford it. Burning straw can really increase the fertilizer efficiency of soil and reduce the occurrence of pests and diseases. This is an ironclad fact.

If straw is allowed to burn, how many pesticides and fertilizers can be reduced? It is not known how much pesticides and fertilizers can be reduced by burning straw. After all, no one will be idle to calculate this. I can only say that burning straw is good for the land and people's farming.

Take the corn planted this year as an example. Just a few days after it appeared, there were already many pests in the corn field. It is estimated that pesticides will be used in these three or two days. Where did these pests come from? There is no doubt that the residue of the last crop lives in the broken straw, so if the straw is burned, these pests will be burned to death. Farmers who often farm land can clearly and intuitively find that since the burning of straw was banned, pests in farmland have generally increased, and it is difficult to eliminate them after all.

The fertilizer efficiency of burning straw is unknown, but we all know that plant ash after burning straw plays an important role in improving soil hardening, increasing soil fertilizer efficiency and completing the comprehensiveness of soil nutrients, especially in improving soil.

But nothing is more important than safety. The fire caused by burning straw is really fierce. You may not know that hundreds of acres of wheat have been ignited, and the wind has helped the fire, which is definitely hopeless. Once the fire causes huge property losses, safety is more important than Mount Tai, so don't worry about the benefits of burning straw. As far as safety is concerned, it really should be banned. After all, human life is a matter of concern, and we can't be careless. I just hope some experts don't take environmental pollution as an example.

As an out-and-out rural banker, there is still suffering.

Since the ban on burning in recent years, the only thing is that pesticides and fertilizers are used more, crop output is not as high as before, air pollution is more serious than before, there are more insects and more crop diseases.
