What will be the effect of the fire on the crops that have been burned by the fire?

The fire can produce a large amount of plant ash, and the plant ash itself has various minerals contained in the plant, and is also an alkaline fertilizer, which can make the soil more fertile after entering the soil layer with rainwater, and the plant ash has a killing effect on a variety of soil bacteria. 2. After the fire, the surface soil layer is called cooked soil, and the high temperature can kill insect eggs and pests within ten centimeters of the soil layer. The soil is softer after burning, which is more conducive to the formation of clump particles in the soil, so that the soil is more permeable.

It will be more conducive to the growth of stubble crops, because the wheat straw that has been burned by fire will turn into plant ash, which is a kind of fertilizer, which fertilizes the soil and indirectly fertilizes the next crop.

Insecticide: In the process of burning wheat plants, the fire will not only burn the harmful bacteria and insect eggs latent on the wheat plants, but also burn the harmful bacteria, pests and insect eggs in the surface soil of the wheat field. In this way, the damage of the next crop to harmful bacteria and pests is greatly reduced.

Straw usually refers to crops such as wheat, rice, corn, potatoes, oilseeds, cotton, sugarcane, etc., and the part left over after farmers harvest the seeds. The straw of these crops is usually discarded and piled up in the ground. They are relatively moist and do not burn completely when ignited.

It produces large amounts of smoke containing dust, droplets, and other pollutants. These fumes are carried by the wind and are harmful to the environment, humans, and other animals. It can cause serious harm and also have a certain negative impact on all aspects of society.

Next, let's talk about how growing crops on fire-burned rice fields affects crops.

Destruction of soil structure, resulting in a decline in the quality of farmland. Straw burning also entered the land. The microorganisms on the surface are burned to death, and the humus and organic matter are mineralized.

Burning straw in the field disrupts the balance of this biological system, changes the physical properties of the soil, increases the compaction of the soil, and destroys the fertility of the soil. It exacerbated the drought and affected the growth of crops. Atmospheric pollution.

Burning straw in the open air directly contributes to air pollution. In spring and autumn, due to the large amount of straw burning, the number of suspended particles in the air increases significantly, and the combustion produces a large number of harmful gases such as carbon monoxide and carbon dioxide, which reduces the quality of the atmospheric environment. Harmful to physical and mental health.

The flue gas produced by straw burning contains a large amount of nitrogen oxides, photochemical oxidants and suspended particles. The burning area and time of straw and rice residue are relatively concentrated, and there is more haze, which has a great impact on middle-aged and elderly people, children and patients with respiratory diseases.

Second, how to solve the problem of straw burning.

First of all, with the village as a unit, we should establish an organizational structure, establish an inspection system, select and send personnel to form an inspection team, supervise and educate the villagers, stop the burning of straw scales in a timely manner, and play a good role in supervision and management. Secondly, in view of the scale of straw burning, detailed rules and regulations should be formulated, the implementation plan and punishment policy should be clarified, and certain rewards should be given to those who report straw burning, and certain fines should be given to straw burning. Finally, strengthen publicity and education. The village committee organizes villagers' meetings, distributes publicity and education leaflets, timely and accurately conveys the significance and specific implementation details of the ban on straw burning, enhances farmers' awareness of the ban on burning, and deepens education, so that we can consciously abide by the rules and regulations on the prohibition of straw burning.

The black ash after the burning of wheat straw is a good fertilizer. It is said that it is not only a fertilizer that is generally lacking in most farmlands, but it is also a high-quality agricultural potassium fertilizer that is easily absorbed by crops. It is also said to be a type of fertilizer that is generally lacking in most farmlands.

In addition, plant ash is alkaline, which has the effect of killing insects and sterilization. In addition, burning straw directly burns the eggs of some crop pests hidden in the straw, making it impossible to reproduce, greatly reducing the degree of insect pests of the next crop, so that the next crop is protected from or less affected by pests and diseases. When the next crop grows vigorously, the yield will increase and the grain production will increase.

Burning fields have been popular in China for thousands of years, and our ancestors had infinite wisdom. According to modern scientific explanations, burning fields produces a large amount of plant ash, and the plant ash itself contains various minerals contained in plants. At the same time, it is an alkaline fertilizer.

When rainwater enters the soil, the soil can be more fertile, and plant ash can kill all kinds of bacteria in the soil.

Extended Materials. According to the analysis of some experts, crop straw mainly contains a large amount of carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, potassium and other elements, as well as some trace elements such as iron, zinc and manganese. After combustion, some greenhouse gases such as sulfur dioxide, carbon dioxide, nitrogen dioxide, carbon monoxide, and some particles, such as dust, are produced. If a certain concentration is reached, it will have a certain impact on the atmosphere and the human respiratory system.

In severe cases, burning straw can still have some impact on the environment. As for how serious the damage is, I don't know that there is a quantifiable standard. At present, prohibiting straw burning in the field in Heilongjiang Province has become a key task, and the burning of straw in the field should be strictly controlled, and comprehensive utilization should be carried out in the form of fertilizer, fuel and substrate.

The effect of straw burning on soil microorganisms in farmland The so-called soil microorganisms refer to the general term for the microorganisms contained in the soil.

Burning straw will burn off part of the organic nutrients in the soil, destroy the soil particle structure, resulting in the alkaline soil, the reduction of water and fertilizer retention, and the reduction of crop yield.

It has a big impact on the crops, because it is likely to pollute the air, and it may affect the growth and development of crops, and it may affect yields, which can lead to slow growth of crops.

It will have a relatively large impact on crops, will also affect the growth of crops, will bring a relatively large crisis to crops, will lead to the death of crops, and will also lead to relatively large damage to the soil.

In the paddy fields burned by the fires, planting crops has no effect on the crops, on the contrary, the crops can grow more vigorously.

It will make the crops die directly and there is no way to germinate again, which will also have a certain impact, and the damage period is relatively high.

Of course it has an impact! In other words, the yield will definitely increase compared to the unburned wheat field and the next crop, which means that all other management measures are the same.

Experienced farmers know that roasted wheat.

The black ash after straw is a good fertilizer, which is said to be a fertilizer that is generally lacking in most farmland, and it is also a high-quality agricultural potassium fertilizer, which is easily absorbed by crops, and it is said that it is also a fertilizer that is generally lacking in most farmland. This means that if more fertilizer is used in addition to artificial fertilization, the next crop will naturally increase yield. And this grass ash.

It is alkaline and also has the effect of insecticidal and sterilization.

Moreover, burning straw directly burns the eggs of some crop pests hidden in the straw, so that it can no longer reproduce, greatly reduces the degree of insect pests of the next crop, and plays a role in protecting the next crop from or less by pests and diseases. When the next crop grows stronger, the yield will increase, and the grain production will increase.

The burned fields have been passed down in China for thousands of years, and the wisdom of the ancestors is endless. With modern scientific explanation, burning fields will produce a large amount of plant ash, and the plant ash itself contains various minerals contained in plants, and at the same time it is an alkaline fertilizer, rainwater can make the soil more fertile after entering the soil layer, and plant ash can kill various germs in the soil.

After the fire, the top layer of soil is called cooked soil, and the high temperature can kill insect eggs, pests, etc. within 10 cm of the soil layer. The burned soil is softer and more conducive to the formation of agglomerated particles in the soil, which makes the soil more breathable.

After burning straw with fire, it is common to see the soil turn pink or black after burning. This is because the organic matter in the soil carbonizes at high temperatures. At the same time, only less than 5 cm of soil is deep, and the physical and chemical properties of the soil cannot be changed.

On the contrary, it has better ventilation and breathability. The ash left behind after the burning of straw is also a good fertilizer, called plant ash.

On the other hand, instead of gathering the straw of the whole field, the straw is spread on the ground and burned. After a fire, the grass ash left behind is a good potassium fertilizer, and at the same time, it can also kill most of the eggs, preventing weeds from growing for a certain period of time.

After the plot of land burned by straw is ploughed, the soil fertility increases, and the number of pests and diseases decreases, which is conducive to the growth of the next crop, with better growth and fewer pests and diseases. It is especially suitable for growing crops that require more potassium fertilizer, such as sweet potatoes, potatoes, eggplants, etc. So there is no need to worry about the adverse effects of straw burning on the next crop.

In any case, to put it bluntly, it is very important that crop straw is burned directly in the field, and it is harmless to the next crop, only good and no harm.

But in recent years, in order to protect the environment.

Quality, crop straw burns a lot of soot and dust, which is said to pollute the environment, so it cannot be burned and is not allowed to be burned, which is a pity. No way, it's important to protect the environment!

In the past, wheat straw was used to make paper, when I was a child, I was the happiest time to beat wheat, I could sell wheat straw to buy popsicles, ice cream, in the 90s of the last century, straw ** did not know what the reason was to stop, and gradually abandoned. The biggest headache for rural people is the current wheat straw. Burning, can't be burned, used, and can't, put it in the ground, not only crop diseases and pests, but also affect the germination of crops.

Does the subject say that the wheat field that was burned by the fire has any effect on the ground below? I can only say that the subject is so happy that you can burn the straw. However, this year, some areas in the north can carry out straw burning in batches, and you don't have to worry about being fined if you carry out straw burning within the specified period.

After burning straw in a fire, it is common to see the soil turn pink or black. This is because the soil is at high temperature, the organic matter in the soil is carbonized, and at the same time, there is only less than 5 cm deep soil, which can not change the physical and chemical properties of the soil, but its ventilation and ventilation performance is better, and the ash left after straw burning is also a good fertilizer, called grass ash.

On the other hand, the burning of wheat fields is not to gather the straw of the whole field together, but to spread the straw on the plot for burning, after the fire, the grass ash left behind is a good potassium fertilizer, and at the same time, it can also destroy most of the insect eggs, and inhibit the weeds from growing in a certain period of time.

After the plot of land burned by straw is ploughed, the fertility of the soil increases, and the base of pests and diseases decreases, which is beneficial to the growth of the next crop, with better growth and fewer pests and diseases. In particular, crops that require a lot of potash, such as sweet potatoes, potatoes, eggplants, etc. So don't worry about the adverse effects of straw burning on the next crop.

You can burn it with confidence! In order to balance the nutrients on the plot, it is best to spread out and burn, and those that need to collect plant ash can be piled up.

That's my personal opinion, I hope it can help you.

The burned wheat fields had no effect on the ground below, but in the spring of the second year, when the wind blows and the rain irrigates them, they will grow and sprout again.

It won't have a big impact, because the fire only destroyed the plant parts on the ground, but the rhizomes in the ground were not damaged, so it won't affect his continued growth.

Of course there is an impact. This is likely to lead to an imbalance in the acidity and alkalinity of the soil, and it is likely that the soil is not suitable for growing crops.

It doesn't matter. Moreover, there is still a lot of ash after the fire burns the wheat field, and it is still possible to add some fertilizer to the soil.

The burned wheat field will not have any effect on the ground below, but will increase the fertility of the land, because the burned wheat straw will have a large fertilizer effect, which can promote the growth of plants.

But all the places that have been burned are black and oily, and the ashes of the plants and trees that have been burned. ConclusionThe bud rice and soybean crops planted by farmers are better than in the past, and there are fewer diseases. However, even if it is a burned wheat field, no matter how beneficial it is to the next stubble, it is also forbidden to burn wheat stubble during the wheat harvest season.

Since once ignited, people cannot manipulate it at all, and it will continue to damage other crops. Therefore, the burning of wheat stubble must be prohibited during the wheat harvest season. Once a fire accident occurs during the wheat harvest season, people are too worried.

Now I think about the fire accident at that time, and my heart still has lingering palpitations. After burning straw in popularity, it is common to see the soil turn pink or gray-black after burning.

This is because the soil is at high temperature, the organic matter in the soil is carbonized, and at the same time, there is only less than 5cm deep soil, which can not change the physical and chemical properties of the soil, but its ventilation and ventilation characteristics are stronger, and the embers left after straw burning are also an effective fertilizer, called plant ash. On the other hand, the burning of wheat fields is not to concentrate the straw of the whole field and then carry it out, but to spread the straw on the land to carry out burning, through the popularity, the grass ash left behind is a good potassium fertilizer, and can also eliminate the vast majority of the larvae, and inhibit the weeds from not easy to emerge in a certain period of time. After the straw is burned, it becomes Panax notoginseng ash soil manure, which is equivalent to fertilizing the next stubble.

In addition, after burning, it also has the effect of hoeing weeds. But after so many years, fire safety has become the top priority, and no one dares to light a fire to roast wheat stubble without authorization. The fire-roasted straw also directly kills some crop insect pest eggs hidden in the straw immediately, so that it will not reproduce again, which greatly reduces the level of pests and diseases of the stubble crops, and has the function of not being affected by or less affected by diseases and maintaining the crops under the stubble.

In short, in the past, very crop straw was immediately burned in the ground, which was beneficial to the next crop, as long as the benefits were not harmful.

In recent years, due to the maintenance of the ecological environment, when crop straw is burned, it will cause a lot of smoke, which is said to cause environmental pollution to the natural environment, so it cannot be burned, and it is forbidden to burn, which must be said to be a kind of defect. If it is a burning wheat stubble, it will be burned in an instant with the wind, and this kind of burning will cause little harm to the next crop. If the amount of straw and wheat bran crops is large, the ignition time is long, and the popularity rate is too slow, it will have an impact on land resources and crops.

It can kill some pathogenic bacteria, insect pests and larvae, grasses and grass seeds on the straw and on the ground and in the shallow part of the ground. Obviously, the planting of crops in the next season can greatly alleviate the probability of the occurrence of diseases and insects, which is helpful for the growth and development of crops.
