Why do you turn the soil before planting vegetables? What is the purpose of this?

By turning the soil, you can use the sun's ultraviolet rays.

Killing and killing pests and eggs stored in the soil makes the next loss of vegetables less susceptible to pests and diseases, less need to use pesticides, and it is more safe to eat by yourself. Second, by turning the soil, the land that was originally built into wooden planks becomes soft and fertile, which is conducive to the rooting and growth of thinning vegetables and increasing yield. Third, the root system of each sparse vegetable is different.

A sparse vegetable like an eggplant has the same root system as a small sapling. If the root system is not destroyed by tilling, the next thinning vegetable will not be able to absorb nutrients and die.

Heavy will grow eggplant young leaves, planting a piece of sparse vegetables winter ploughing is a common agricultural operation in the past, but now many farmers have omitted this step, which is the same reason as the steaming scaffold, the steaming shelf is in summer, using the high temperature of organic fertilizer fermentation, while reducing pests and diseases in the soil, while fertilizing the soil. In fact, there are many benefits of arriving land in winter. A large amount of land is planted continuously, coupled with the irrational application of chemical fertilizers, and a large amount of non-degradable substances remain in the soil.

There may be knots, watering and fertilization can only be on the surface, the utilization rate is not high, after turning the soil, the soil below is turned over, the structure of the soil is improved, the soil is loose, which is conducive to the growth of crops, and the plants that change the soil moisture like to grow in a humid environment, but the soil is too dry to be conducive to the growth of crops. Therefore, to change the paving and loosening of the soil, it is necessary to use the cultivation of the soil to make up for the shortcomings, if the soil is too sticky, the humidity will become high, the air permeability will become poor, which is not conducive to the growth of crops, and is prone to root rot and other viral diseases.

On the other hand, when the soil is too loose and the water-holding and fertilizing ability is poor, fertilization should be carried out to improve soil viscosity and promote crop harvest. According to the depth of root penetration, distribution breadth, number of branches, and root hair development, the soil nutrient absorption of various vegetables is large and small.

This can be disinfected and sterilized, the soil can become more soft, and the drainage can be better, the purpose of this is to make the plants grow better.

The main purpose is to create good planting conditions, which can be disinfected and sterilized, and fertility can also be improved. The main thing is to ensure the nutrients of the soil, which can kill the bacteria in the soil.

In this way, the fertility of the soil can be guaranteed, and then the soil can be made more crisp, and then the temperature can be increased, which can reduce the temperature of the soil, and then the seeds can be better breathed.

Loosen the soil first, then dig the ground.

First, the steps of novice planting vegetables:

1. First of all, you need to find a piece of land suitable for your own cultivation, and choose the size of the land to grow vegetables.

2. Then use a hoe.

Loosen the soil, constantly turning the soil up and removing some weeds.

3. Sow seeds, dig small soil pits of suitable size in the land, put the seeds in, and water them.

4. After treatment, pay attention to watering and weeding every day.

2. What other skills do farmers have for growing vegetables?

For vegetables, fertilizer is very important and indispensable. For experienced vegetable farmers, they have accumulated a lot of experience in production practice, which can be summarized as vegetable fertilization, sky fertilization, and fertilizer fertilization. Let's take a look at how to do it.

1. Watch the vegetables and fertilize.

Different varieties of vegetables, the amount of fertilizer is not the same, if the fruit and vegetables and melons are planted, in addition to nitrogen fertilizer, phosphorus and potassium fertilizers are also needed, and the soil chef can be used to polymerize potassium dihydrogen phosphate.

Phosphorus and potassium supplementation.

2. Look at the sky and fertilize.

The main factors that influence fertilization are climatic factors such as temperature, precipitation, and light. When the temperature is high, the crop grows vigorously and requires more fertilizer, so more fertilizer can be applied in the growing season when the temperature is suitable, and less or no fertilizer can be applied in the low temperature season.

3. Look at fertilizer and fertilization.

In the process of fertilization of vegetable planting, inorganic fertilizer and organic fertilizer are gathered, organic fertilizer is used as base fertilizer and top dressing, most of the inorganic fertilizer is used as top dressing, and in some cases, inorganic fertilizer is used as base fertilizer.

In addition to soil fertilization, vegetable planting can also be topdressing outside the roots. However, it is better to use chemical fertilizers of pure quality that do not easily cauterize the foliage.

Urea is more commonly used.

Soil chef polymerizes potassium dihydrogen phosphate, as well as trace element fertilizers.

Loosen the soil first, then dig a pit, sow seeds, then cover the soil, water it, and fertilize it.

Since ancient China more than 1,000 years ago, the ancestors of Chinese farmers knew that before planting stumps and sparse vegetables, the land had to be turned over deeply. Why do you have to turn the soil before planting sparse vegetables?

In fact, as long as the old farmers know this truth, whether they know how to read or write, they know better than anyone else. The main purpose of turning the soil is:

First, by turning the soil, the sun's ultraviolet rays can kill and kill the pests and eggs in the soil, so that the next stubble of vegetables is less affected by pests and diseases, and there is no need to use too many pesticides, and you can eat more at ease. Second, by turning the soil, the originally compacted land can become soft and fertile, which is more conducive to the rooting and growth of thinning vegetables, and achieves the purpose of increasing yield. Third, the root system of each kind of sparse vegetables is different, like eggplant sparse vegetables, its root system is similar to that of small saplings, if you do not destroy its root system by turning over the soil, then your next stubble of sparse vegetables, light will not absorb nutrients and die, heavy eggplant buds and leaves come out, directly the next stubble of sparse vegetables you planted is dead.

All in all, soil is the basis for the survival of crops, and high crop yields, short growth periods, and high multiple cropping indexes require fertile soil. Due to the differences in the depth of root system, the breadth of distribution, the number of branches, and the development of root hairs, the absorption of soil nutrients by various vegetables varies greatly. Therefore, when the soil is ploughed, it should be deep and deep, it should be shallow, the depth of ploughing should be within 20 cm, and the special requirements of crops should not exceed 30 cm, and the soil should not be harmful to crops except for nitrification, and according to the season and the growth of crops, spring ploughing, summer ploughing, autumn ploughing and winter ploughing should be taken respectively.

The subject is what we often call turning the soil, because deep turning the soil has several good effects, which can improve the growth efficiency of crops and reduce the occurrence of diseases

First, deep ploughing loosens the soil

The soil we are familiar with is thick and hard, and the porosity of such soil is relatively dense and the permeability is relatively poor, and if it is directly sown and planted, the root system is not easy to take root, and the water and fertilizer cannot penetrate well. After deep ploughing, the soil becomes loose, so it is more conducive to the growth of crops, not only the root system is easier to root, the water retention capacity of the soil will also be improved, and the soil aeration is also improved, which is conducive to the sowing and development of crops;

Second, deep tillage can reduce the occurrence of diseases

Vegetable planting is most afraid of soil-borne diseases, after the end of a year of planting, many germs, insect eggs are stored in the deep soil, if not deep ploughing, the germs continue to multiply in the soil, will inevitably affect the next year's crop growth. Through deep ploughing of the soil, the deep soil can be turned out, and the germs and insect eggs can be killed after sun exposure, and then combined with pesticides, root irrigation and other methods, soil-borne diseases can be prevented from occurring in the following year.

Third, deep tillage can improve soil fertility

Many people think that the nutrients for crop growth rely on fertilizer, but in fact, the nutrients in the soil also have a great impact on crop growth, and most of the nutrients for crop growth come from the soil.

Crop residues and organic fertilizer applied to the topsoil layer are buried in the lower layer, creating favorable conditions for the survival, reproduction and activity of microorganisms, accelerating the process of soil maturation, and ultimately improving the fertilizer efficiency of organic fertilizer and improving soil conditions through the decomposition and transformation of soil microorganisms.

Fourth, deep tillage can restore soil structure

The soil that has been planted for many years has been damaged to a great extent, and these soils will be compacted and salinized.

In the case of deep ploughing, the upper layer of soil with poor structure can be turned over to the lower layer, and these soils are gradually restored in the deep soil, and then turned over to the upper layer of the soil during deep ploughing in the following year, so that the cycle is repeated, which is a kind of protection for the soil and can also restore the soil structure.

Therefore, there are many benefits of deep soil ploughing, but it is also necessary to pay attention to the time and depth of deep ploughing. The time of deep ploughing is generally the best time to choose deep ploughing after the crop harvest, at this time, the stubble on the ground can be turned into the deep soil, and it can become fertilizer after decaying; The depth of deep ploughing should be adapted to local conditions, for example, deep ploughing in arid areas should be shallower and saline-alkali land.

Deep ploughing is relatively deeper.

Because the soil will be very loose, easier to breathe, easier to absorb nutrients, and can make the survival rate of seeds relatively high, the yield will be higher.

The land is re-tilled to ensure that the moisture and temperature of the soil inside are suitable. At the same time, the small insects inside run outside, and by the time they are planted, there are no eggs.

This loosens the soil, increases the permeability of the soil, removes germs from the soil, and reduces pests and diseases.

The soil is soft and breathable, so the rainwater can easily be retained in the soil, and the air can enter the soil, and at the same time, when the soil is turned, it can also kill some of the insects hiding in the soil, so that the seeds sown in it can easily germinate and grow. Secondly, the method of changing soil compaction and looseness is to use soil tillage to supplement the surplus.

Why do you turn over the soil before planting vegetables?

The soil is soft and breathable, so rainwater can easily be retained in the soil and air can enter the soil.

At the same time, when turning the soil,It also kills some insects hiding in the soilIn this way, the seeds sown in it can easily germinate and grow. Here are some examples of its specific value:

1. Increase soil permeability

The permeability of the soil depends on the amount of aggregate material in the soil structure.

The more aggregates in the soil, the larger the gap in the soil, the looser the soil, the stronger the soil permeability, and the better the extensibility of plant roots, which is conducive to the absorption and utilization of nutrients by plant roots.

2. Eliminate harmful components in the soil

Due to the long-term continuous cultivation of vegetables in the vegetable field, a large number of chemical fertilizers and various pesticides are applied to the soil of the vegetable field, as well as the root system left by the plant in the soil, the plant root system will decay under the action of microorganisms and produce harmful gases.

If these fertilizers, pesticides and harmful gases are not discharged in time, they will cause harm to the crops, so the harmful substances stored in the soil are eliminated with the help of cultivating and turning the soil.

3. It is conducive to fertilization, burying and cultivating the soil

It can also take the opportunity to bury the residue and leaves on the soil surface, bury farmhouse fertilizer on the soil, effectively increase soil organic matter, reduce soil surface weeds and seeds, enhance soil fertility, and improve soil circulation structure.

4. Eliminate pests and diseases in the soil

In the case of density utilization of vegetable gardens, various soil-borne viruses and pest eggs are also widely present in the soil layer.

In order to reduce pests and diseases, the use of cultivating and turning the soil can effectively reduce the occurrence of pests and diseases, especially for winter ploughing, which can turn out the pupa and eggs of pests and insects that are born in the soil and freeze to death, so as to reduce the occurrence of pests and diseases in spring.

5. Change soil moisture

Plants prefer to grow in a moist environment, but if the soil is too dry or too wet, it is not conducive to the slow growth of crops. Therefore, the way to change soil compaction and loosening is to use soil tillage to supplement the surplus.

Whether it is good to turn the soil wet or dry before planting vegetables.

Whether the vegetable patch is watered or ploughed firstThere is no exact regulation or explanation for this, and it can only be determined according to the situation on the ground at that time.

In autumn, the temperature is too high, the soil is seriously short of water, and the planting of direct seeding vegetables must be watered first, and after an interval of three to five days, you can turn the ground and plant vegetables intensively.

If it is a vegetable seedling, it is necessary to plough the ground intensively, adjust the drainage ditch to plant the vegetable seedlings, and water the vegetable seedlings thoroughly after completely planting them.

1. Loose soil: The soil quality of the turned soil is more loose and the air permeability is stronger. 2. Disinfection and sterilization

Allow ultraviolet rays to fully irradiate the soil and kill insects and germs in it. 3. Sufficient fertility: make the fertilizer fully penetrate into the soil.

4. Precautions: According to the season and the growth of crops, spring ploughing, summer ploughing, autumn ploughing and winter ploughing should be adopted respectively.

1. Loose soil

The soil is turned before planting because the soil is looser and more breathable, which can retain water and oxygen in the soil, which is conducive to improving the air permeability and water retention during the growth of crops.

2. Disinfection and sterilization

Turning the soil deep once before planting can allow ultraviolet rays to fully irradiate the soil, kill insects and germs in it, effectively reduce the chance of infection of pests and diseases, and improve the germination rate of seeds.

3. Sufficient fertility

Before planting, the soil is deeply turned, and then applied to the well-rotted farmhouse fertilizer or organic fertilizer, which can make the fertilizer fully penetrate into the soil, which is conducive to improving the fertility of the soil, promoting seed germination and plant growth.

4. Precautions

When the soil is ploughed, the depth of ploughing should be maintained within 20 cm, and the soil that is too deep ploughing has no benefit except for nitrification of crops, and according to the season and the growth of crops, spring ploughing, summer ploughing, autumn ploughing and winter ploughing should be taken respectively.
