In recent years, I have seen many farmers buy quicklime and sprinkle it on their fields, what is the

In the past, crops grown in rural areas were mainly based on organic fertilizers, which mainly included human manure and pig dung, cow dung, etc., and firewood and soil were used to burn grass and wood compost. With the development of rural economy and society, the application of chemical fertilizers has become very extensive. Now farmers are farming, most of them use our common urea, potassium dihydrogen phosphate, phosphorus pentoxide and other chemical fertilizers, including a variety of binary or ternary compound fertilizers and various trace element fertilizers.

This kind of chemical fertilizer has simple composition and high nutrient content, so the fertilizer effect is fast, the fertilizer strength is strong, and it can quickly absorb crops and achieve the effect of increasing yield.

However, chemical fertilizers are generally inorganic fertilizers, which do not contain organic matter, and long-term use can not only not improve soil properties, but also cause poor soil, serious pollution, and damage to the ecological environment. Therefore, after using chemical fertilizers for a long time, many farmers find that no matter how much fertilizer is increased, the growth of crops is still not good, the yield is not high, and even pests and diseases will appear. The reason is that the long-term application of chemical fertilizers leads to soil malnutrition, aggravates the consumption of phosphorus and potassium in the soil, reduces the activity of soil microorganisms, and leads to serious soil oxidation.

So, after years of farming, the farmers sprinkled quicklime on top. Why are you doing this?

It mainly has the following important roles. First, quicklime can improve acidified soils. Due to the long-term use of chemical fertilizers in many lands in China, soil oxidation is more serious.

The main measure of acid soil improvement in soil improvement is the rapid improvement of soil with quicklime. Because the main component of quicklime is calcium oxide, which is an alkaline substance, it can neutralize the over-oxidized soil, regulate the acidity balance of the soil, and reach or restore normal levels. This method is economical and fast, and it allows for soil improvement.

Second, quicklime has a disinfection and sterilization effect. We all know that there will be a large number of germs and microorganisms in the soil after long-term planting, and even insect eggs.

This harmful germ and eggs are very bad for the growth of crops. Sprinkle quicklime into the field, and the quicklime reacts when it encounters water, so that the calcium hydroxide becomes strongly alkaline, which can play a good role in disinfection and sterilization. Because both bacteria and eggs have proteins, they will lose their activity when encountering alkalis with strong proteins, achieving a bactericidal effect.

In addition, quicklime reacts with water, which can release a lot of heat to kill pests. Third, quicklime can improve soil nutrient status. The main component of quicklime is calcium oxide, which can increase the calcium content in the soil after being used in the farmland, so that crops can absorb more balanced trace elements and promote crop growth.

At the same time, after quicklime meets water to form calcium hydroxide, it can improve the soil properties to a certain extent, improve viscosity, retain water, improve soil permeability, help the respiration and growth of crop roots, and provide more beneficial living space for the activities of microorganisms. However, when using quicklime, it must be used rationally according to the actual situation, and excessive use will lead to alkaline soil and malnutrition. In addition, it is necessary to take protective measures and not let the quicklime dazzle to avoid accidents.

On the one hand, the purpose of this is to sterilize the land and ensure that the crops are not infected by bacteria; On the other hand, it is to change the pH of the soil and make the soil more fertile.

It has the function of medicine, and when used together with fertilizer, it can get rid of pests, which not only saves fertilizer, but also plays a role in eliminating pesticides, killing two birds with one stone.

Because quicklime can kill bacteria, sprinkling quicklime in the farmland can kill the parasites and eggs in the farmland.

Because of the special substances contained in quicklime, they can make the land more fertile, and can also play a role in sterilization and poison to protect the better growth of crops.

In fact, the effect is to make the land warmer, because the quicklime reacts with the air and will release heat.

It may be to fertilize the effect, because some substances in quicklime can also promote the growth of crops.

Doing so will keep the fields free of pests, so that the grain you grow can be harvested, and your grain will be sold at a good price in the fall.

Doing so can improve the disease resistance of the crop, which in turn can also increase the yield of the crop.

Because lime can play an insecticidal role, many farmers will sprinkle some lime in their fields, which will reduce the damage of crops to pests.

This is done because quicklime can kill parasites and eggs in the field, and the crops will grow better in the future.

Many farmers sprinkle quicklime into their fields in order to neutralize the acids in the fields and make them easier for crop cultivation.

1.Quicklime can improve acidified soils. Due to the long-term use of chemical fertilizers in many lands in China, soil oxidation is more serious.

The main component of quicklime is calcium oxide, which is an alkaline substance that can neutralize over-oxidized soil and regulate the acidity balance of the soil. 2.Quicklime has a disinfection and sterilization effect.

Destroys germs and microorganisms, even eggs. 3.Quicklime can improve the nutrient status of the soil.

The main component of quicklime is calcium oxide, which can increase the calcium content in the soil and promote crop growth after being used in farmland. The soil properties are improved to a certain extent, increasing the viscosity and retaining moisture.

The purpose of this is to keep the plants more insulated, so that they do not freeze to death after snowfall, because this lime powder has special properties and can generate heat.

In this way, it can effectively kill and sterilize pests in the farmland, and it can also increase the nutrients and fertilizers of the soil, which is very good for the soil.

In fact, this is not just a matter of the past few years, because farmers began to use quicklime in the gas for air oxidation several years ago, and then turned into powder and sprinkled in the field. In view of the fact that some compacted land resources are indeed sprinkled with quicklime, the situation of land resource compaction has been improved, and the land resources have a slightly loose situation, which has indeed the actual effect of farmers getting rich on crops, and has great benefits in improving the growth environment of crops.

In the past, farmers polluted the ecological environment by adapting measures to local conditions and polluting the ecological environment in the case of quicklime formation in production and manufacturing. Today, most of the rural manufacturing factories, the stone pang, have been eliminated, which is a major loss for the farmers. It is one of the reasons why all kinds of serious illnesses have been vacated for so many years.

The production of quicklime is so bad that it is manipulated, and many chemical fertilizers are used. In recent years, quicklime that can be bought in the countryside is a white precipitated chemical formed by chemical changes with water. Also known as hydrated lime.

Hydrated lime should be applied in the field and sprinkled on the ground in the case of turning the soil, and it will enter the soil with the ploughing, and it is not easy to cause damage to the crops through the combination of soil. It can also be used in combination with green manure crops and wheat straw returning to the field. If applied during the growth season, it will burn the rhizome and impeller, etc., and will cause damage to food crops.

For fruit trees, in order to improve the soil, there are also sprinkled in the upper fertilizer pit in autumn and winter, and some are sprinkled on the ground and turned over. Practical experience has proved that the sprinkling of lime powder can reasonably increase the pH of soil.

Hydrated lime application to the soil can improve compaction. In the lower reaches of the Yangtze River, soil compaction is often seen, which is related to the soil parent material, and is also inseparable from the long-term continuous crop planting, lack of organic fertilizers and trace elements. When hydrated lime is applied to the soil, the soil structure changes and the looseness level increases.

Because quicklime is strongly alkaline, many bacteria, viruses and insect pests are particularly sensitive to quicklime, and lime powder will cause a lot of heat when the air in the field is oxidized.

Mainly because the long-term use of chemical fertilizers leads to the loss of soil water and nutrients, sprinkling lime can improve the acidification of the soil, so many people sprinkle lime into the soil in order to improve the soil environment.

Quicklime has a restorative function, which means that it can improve the soil, which is conducive to growing crops and making it grow better.

In recent years, some farmers have bought quicklime powder to sprinkle in their fields. What the hell is going on? Can it be used as fertilizer?

I am a rural kid and have been exposed to lime since I was young, but it was used as a construction engineering material. Can raw gray help crops grow in the field? Practice has proven to be possible.

After lime powder, many balanced rice fields have improved and there are many common pests. What is the reason for this? Mainly, the chemical reaction effect of raw stone acid is mainly used, and the physical and chemical structure of the farmland is improved.

When we call quicklime, it's calcium oxide. It is actually natural rocks that are usually burned by calcium carbonate at high temperatures, and these people are calcium carbonate. After incineration, they are broken down into calcium oxide and calcium carbon, which is what we call calcium oxide.

To say that Roweii is a substance that has many natural rocks by incineration.

Quicklime will be cut into calcium bicarbonate when exposed to water, which is mainly alkaline. For some acidic soils, after turning far away, we scatter some of the original lime, and then after dissolving, these survival rates will be fully neutralized in the soil. Finally, it improves the role of soil pH.

By reducing the acidity of the soil, there is also the problem of lowering the land strip, which is very advantageous for growing crops.

Especially for some usually stubborn plots, after several years of continuous cultivation, the soil begins to stiffen. If you plant crops at this time, then the fish suddenly loosen and the roots of the crops cannot breathe well, which eventually affects the crop. Grow.

Especially when we grow sweet potatoes, if the soil is long, it is serious. Then this is not suitable for growing sweet potatoes, even if it is difficult to grow sweet potatoes and the output is relatively low, sweet potatoes are small and have a very low sweetness.

All in all, there is less rough in the soil in which the crops are grown. It can improve the acidity and alkalinity of the soil, which ultimately enables the soil to achieve an environment and conditions suitable for crop growth. In addition, the acidity of the soil is reduced, and then the situation of banding suddenly occurs, so it is more conducive to fertilizing crops and watering.

In addition, people in rural areas will have some quicklime when cleaning the fish ponds. This can also play a good role in disinfection. It can be said that quicklime is widely used in agricultural production.

Quicklime is sprinkled in the farmland because the farmland has been used with chemical fertilizers for a long time, and the soil is seriously acidified, and the alkalinity of quicklime can neutralize the soil acidity, which can increase the soil viscosity and increase the yield.

Of course, in order to improve the soil, lime contains alkali, which can neutralize acidic soil, which is conducive to changing the properties of the soil, and then used as calcium fertilizer to improve the fertility of the soil.

The problem of soil compaction in farmland may be due to factors such as the acidic nature of the soil, and quicklime can solve this problem, so many farmers will sprinkle quicklime on the farmland.

I remember when I was a child, in the countryside of my hometown, I would often see the farmer uncle buying lime and scattering it in the field, which felt very strange and fun. Later, I asked Uncle Farmer,They just say quicklime, it's calcium oxide. Generally, after the harvest, the soil in the field will be very hard and there is no fertilizer, so some quicklime should be sprinkled at this time.

Sprinkle quicklime for the following purposes:

First, bactericidal effect

After the quicklime is incinerated, it is decomposed into calcium oxide and carbon oxide, that is to say, quicklime is a substance formed by incineration of many natural rocks, generally in the fish pond or field in the countryside, farmers in order to reduce the bacteria in the field, they use quicklime sterilization and disinfection, especially the fish pond, which is often disinfected by this method.

2. Improve soil properties

Quicklime will be cut into calcium bicarbonate when it encounters water, and it is mainly an alkaline substance. In the rural fields, the soil is more acidic, and the farmer usually sprinkles some quicklime after ploughing, so that the survival will be dissolved and the acidity in the soil can be fully neutralized. In the end, it has the effect of improving the pH of the soil.

By reducing soil acidity, which also reduces soil compaction and other problems, it is very good for the growth of crops, in fact, farmers are still very smart, good at using such methods, and these methods are from the hands of farmers, generation after generation of experience.

3. Increase the activity of soil microorganisms

In fact, many experienced farmers in the countryside know that after several years of continuous cultivation, the soil begins to harden and become stiff. If crops are planted at this time, the plants will not get more nutrients, which will eventually affect the growth of crops. If the soil is compacted for a long time, especially if the acidification is severe.

Then this kind of emergence is not suitable for growing food, even if the planting is more difficult, and the yield is relatively low, the plants that grow are not delicious, and feel that there is no nutrition. Therefore, it is necessary to sprinkle lime to increase the activity of microorganisms in the land, so that the land is full of nutrients, and the plants planted can be harvested.

It must be useful to prevent the soil from clumping, otherwise it will not be sprinkled into it.
