Soil compaction in the field is particularly serious, how can it be improved?

Now the soil is really very. I believe that the farmer's friends should have no strangers, such as questions, absolutely heard. The problem is actually very well understood, the soil should be a relatively loose one, such as the soil dug from the shovel should be very loose, but the soil of the plate is difficult, and the shovel is also a whole piece.

A whole piece. It is very difficult for this kind of earth to achieve this appearance, and the plants are fundamentally natural to grow.

Why agriculture has been good for so many years, in this time there are so many problems this time, it is actually reasonable to pay attention to the search for the causes that can be effectively improved, and today and everyone is just talking about some of the hazards of wind in the soil. How it was formed, how should I improve.

One, harm. There is a problem with the surface of the soil, the danger can be very much, because the roots of the plant grow in the soil, and if he becomes very hard, the roots are not good and do not absorb nutrients, then the crop is naturally long is bad. In addition, this soil is very poorly aerated and the roots of the plant also breathe in the soil, which will be easily caused by respiration.

Second, the reason for the reason.

Soils have a variety of problems. In fact, the misuse of fertilizers is linked to relationships. Previously, we used traditional fertilizers that were thousands of years old.

This not only damages the soil, but also has a use for the soil. The effect of improvement forms a good virtuous cycle, but after the fertilizer, it cannot be used by the plant and will remain in the soil.

In this case, some beneficial organisms in the soil will die slowly. It turns out that loose soil will not be able to maintain the structure, and there will be problems with taper. This soil has poor storage capacity and poor air permeability.

Third, how to improve.

Since I knew the problem, I naturally knew how to improve, then it was necessary to use fertilizer rationally. The use of fertilizers should never be excessive, taking care to understand the needs of the crop or be based mainly on traditional organic fertilizers. In this way, it can reach more beneficial organisms in the soil.

When watering, it should also be noted that do not water, it is easy to cause slate. At the same time, the soil often becomes soil, making the soil more breathable.

To improve soil pH, soil compaction is mainly due to the use of chemical fertilizers, chemical fertilizers with high sulfur content are easy to lead to soil compaction, the best way to solve the problem is to reduce the use of chemical fertilizers, increase the use of organic fertilizers, farm fertilizers, biological fertilizers, in addition, deep tillage, soil conditioners can also be alleviated.

Soil compaction improvement method: rational use of chemical fertilizers, pay attention to the use of high-quality organic fertilizers; increase the input of beneficial bacteria; Crushing crop straw and returning it to the field can improve soil structure, and covering the land with straw residue can reduce soil erosion.

If the soil has the problem of slabbing, it can be very harmful, because the roots of the plant grow in the soil, if it becomes very hard, the root system does not grow well, can not absorb nutrients well, then the crop will naturally not grow well. In addition, the air permeability of this soil is very poor, and the roots of plants also have to breathe in the soil, and if they can't breathe, it will easily cause death. The reason why there are various problems in the soil, in fact, is inseparable from the abuse of chemical fertilizers, before we have been cultivating for thousands of years are using some traditional fertilizers, which not only will not harm the soil, but have an improvement effect on the soil, forming a good virtuous circle, but after the fertilizer is used too much, it can not be used by plants, and it will remain in the soil.

Once the soil is compacted, it is good to turn him over a few times with a hoe.

Soil compaction? A method of improvement that does not cost money.

Ask how to loosen the yellow mud.

Reasonable watering: Adjust the watering method, watering a small amount and multiple times, to avoid heavy rain washing away a small amount of soil.

Ask what farmyard fertilizer.

Ask questions to loosen the mud quickly.

1. Rational use of chemical fertilizers and attach importance to the use of high-quality organic fertilizers. Excessive mineral elements will lead to the formation of aggregate structure, soil compaction is caused by unreasonable fertilization, the bottom fertilizer should be based on organic fertilizer, chemical fertilizer is used less or not used, and the middle and late top dressing is mainly water-soluble fertilizer with high absorption efficiency.

2. Increase the input of beneficial bacteria. The organic fertilizer applied to the improved compacted soil needs a large number of soil microorganisms to decompose, and the supplement of beneficial microorganisms in the soil should be increased while supplementing the organic fertilizer.

3. Crushing crop straw and returning it to the field can improve the soil structure, and straw residue covering the land can reduce soil erosion.

4. Use large machinery to carry out deep ploughing and land preparation to improve the structure of the cultivated layer and the circulation of air.

5. Reduce the number of times the locomotive enters the cultivated land and prevent the land from being repeatedly crushed.

I'm a native of the city. Cold sensitivity. Someone who knows a little about the land.

Understand. If the land is annually on the fertilizer so that the land is dissolved. No floating powder, so we recommend that you be sure to apply more farm fertilizer, so that.

It can also play. Environmental performance. It's better to keep the land noisy.

Methods for rapid improvement of soil compaction:

1. Artificial loosening soil.

When the soil is compacted, the first thing we should do is to loosen the soil manually. Use a hoe or shovel to loosen the soil with a surface of 3-5cm to increase air permeability.

2. Sprinkle unleavened rapeseed cake.

After loosening the soil on the surface, sprinkle unfermented rapeseed cake powder on the surface of the soil, sprinkle a thin layer, do not sprinkle more, so as not to cause fertilizer. During the fermentation process of rapeseed cake flour, there will be many microorganisms, which can make the soil much looser. You can sprinkle once every half a month, and you can keep the soil loose several times in a row, and you can also replenish fertility for the month.

3. Surface covering.

If there is a lot of rain, or if you water frequently, the water flow is easy to cause soil compaction, and you can cover the soil surface with large pine scales, gravel, etc., blocking the impulse of the water flow, and also reducing the situation of compaction.

Hazards of soil compaction:

1. The respiration of the root system of the plant is obstructed.

In the case of soil compaction or long-term flooding, the cellular respiration of plant roots is weakened, and nutrients such as nitrogen mostly exist in an ionic state, and the absorption is mostly in the mode of active transportation, which consumes the energy produced by cell metabolism. Breathing is weakened, so the energy ** is insufficient, which affects absorption.

2. The root system of the plant cannot develop normally.

Soil aggregate structure is an important indicator of soil fertility, and the destruction of soil aggregate structure leads to the reduction of soil water retention, fertilizer retention capacity and permeability, resulting in soil compaction, and the root system of plants in this state will decline their vitality due to lack of oxygen.

3. Cause plant deficiency disease.

The symptoms of plant deficiency are not necessarily due to the lack of this element in the soil, but due to a series of problems such as soil compaction, unsuitable soil pH, or unbalanced soil moisture, which are caused by the decline of root absorption capacity.

Causes, hazards and treatment methods of soil compaction (Part I).

Don't be afraid of soil compaction, teach you a few tricks, don't turn over the pot and don't pour the soil, easy to solve.

Soil compaction with drilling to run loosening agent, loosening soil like a steamed sponge, there are pores, **on the search, you can try it.

Soil aggregate structure is an important indicator of soil fertility, and the destruction of soil aggregate structure leads to the reduction of soil water retention, fertilizer retention capacity and permeability, resulting in soil compaction.

The content of organic matter is an important indicator of soil fertility and aggregate structure, and the decrease of organic matter leads to soil compaction. Soil organic matter is an important component of soil aggregate structure. The decomposition of soil organic matter is achieved by the activity of microorganisms.

After excessive application of nitrogen fertilizer to the soil, the nitrogen ** of microorganisms increases by 1 part, and the corresponding carbon consumption increases by 25 parts, and the carbon consumed ** is low in soil organic matter, which affects the activity of microorganisms, thereby affecting the formation of soil aggregate structure and leading to soil compaction.

The soil aggregate structure is formed by the connection of negatively charged soil clay and organic matter through positively charged polyvalent cations. Multivalent cations connect soil particles into large particles in the form of bond bridges to form a soil aggregate structure. When excessive application of phosphate fertilizer to the soil, the phosphate ions in the phosphate fertilizer combine with the cations such as calcium and magnesium in the soil to form insoluble phosphate, which wastes phosphate fertilizer and destroys the soil aggregate structure, resulting in soil compaction.

When excessive potassium fertilizer is applied to the soil, the potassium ion displacement in the potash fertilizer is particularly strong, which can replace the polyvalent cations that form the soil aggregate structure, while the monovalent potassium ions do not have the role of bond bridge, and the bond bridge of the soil aggregate structure is destroyed, which also destroys the aggregate structure, resulting in soil compaction.

In addition to the above-mentioned fertilization problems, soil salinization and irrational tillage can also cause soil compaction.

The more common solution is to increase organic fertilizer, deep ploughing, planting green manure, and applying some calcium-containing magnesium fertilizer.

The improvement methods of soil compaction include: artificial loosening of soil, sprinkling rapeseed cake, sprinkling gravel, etc.

1. Artificial loosening soil.

When the soil is compacted, the first thing to do is to carry out artificial loosening, and use a hoe or shovel to dig up the top layer of 3-5 cm of soil to loosen the soil, so as to increase the air permeability of the soil and promote the respiration of plant roots.

2. Sprinkle rapeseed cakes to accompany the old.

After loosening the surface of the soil, the unfermented rapeseed cake is crushed, and then sprinkled on the soil surface, sprinkled with a thin layer, so as not to cause fertilizer, rapeseed cake in the process of fermentation, will produce a lot of microorganisms, can make the soil loose.

3. Sprinkle gravel.

In the case of more rain in the summer collapse season, or often watering the soil, the water flow is easy to cause soil compaction, at this time, the soil surface can be covered with a layer of earth pine scales, gravel, etc., to block the impact of water flow, reduce the phenomenon of soil compaction.

The importance of soil for crop growth

1. Provide matrix.

Soil provides a substrate for the growth of crops, it is a loose surface layer on the surface of the lithosphere that can grow plants, it is the substrate for the life of land plants, it provides the necessary mineral elements and water for the growth of crops, and it is an important place for the exchange of materials and abilities in the ecosystem.

2. Decompose organic matter.

The soil contains a large number of microorganisms and invertebrates, in which microorganisms can decompose organic matter, so that it can be directly used by crops to provide nutrients for the growth of crops, and the earthworms in the soil can also achieve the purpose of turning the soil through physiological effects, increasing the oxygen content in the Lusheng soil.

3. Protect crops.

The soil protects the crops from external environmental factors, ensures that the root system grows in a stable state, and can also play a role in stabilizing the plants when typhoons and floods hit, so that they are not easily damaged.

1.Tap water must be dried before use. Before watering the flowers, put the tap water in the sun for 2 days, which can volatilize the chlorine in it, and the water temperature can be raised a little, so that it will not be particularly cold. This kind of water is better for the flowers, and it is not easy to cause soil compaction.

2.When applying organic fertilizer, it must be used after it is decomposed, otherwise it is easy for the soil to be compacted and the root system is not good. It's like a flower for washing rice. If you want to bask in the sun for 2 months, you will find that the supernatant becomes transparent and clear, which is rotten. Watering the flowers with 30 times the water works best.

3.Flower pots should be replaced every 1-2 years. The repotting time should be concentrated in spring and autumn as much as possible.

These two seasons are not particularly cold or particularly hot, and it is a good time to change the pot. Try not to change the pot in the hot winter or summer. If the temperature is too low or too high, it is very dangerous for the flowers.

Soil compaction may be caused by a lack of organic matter, so it is necessary to turn the soil and add peat soil, perlite, etc. to make the soil loose and fertile. After the soil is compacted, the diluted potassium dihydrogen sulfate solution can also be poured into the soil to alleviate it. If the situation is more severe, it is necessary to change the soil again for cultivation.

Soil compaction may be caused by a lack of organic matter, which is turned over and mixed with peat, perlite, humus and manure to increase the organic matter content of the soil and make it loose and fertile.

After the soil is compacted, you can also pour the diluted potassium dihydrogen phosphate solution into the soil to reduce the alkaline matter in the soil and keep the soil in a healthy state, in addition, it needs to be watered every 1 month to make the potting soil more soft.

After the soil is compacted, it is necessary to change the soil in time, and the appropriate soil can be selected according to the growth needs of the plant, and it is recommended to put cinder, river sand, and nutrient soil. The soil is mixed to make a substrate for cultivation to make the soil soft, and the soil can also be mixed with an appropriate amount of organic fertilizer to improve the fertility of the soil.

Long-term lack of water will also lead to soil compaction, at this time you can pour a lot of water into the soil, soak all the soil, and after the soil absorbs enough water, then properly kill the red loose soil, and discharge the excess water.
