Why plough the soil before planting? Why do you turn the soil before planting?

1. Loose soil: The ploughed land is looser and more breathable, which is conducive to soil retention of water and oxygen. 2. Disinfection and sterilization

After ploughing, the soil can be fully irradiated by ultraviolet rays, and the bacteria and pests in it will be killed, which can reduce the probability of pests and diseases. 3. Improve fertility: After ploughing, apply sufficient well-rotted farmhouse fertilizer or other organic fertilizer, and the fertilizer can penetrate into the soil, thereby improving fertility.

4. Precautions: The depth of ploughing should be kept within 20 cm to avoid nitrification of crops, and spring ploughing, summer ploughing, autumn ploughing and winter ploughing can be selected according to the season.

1. Why do you turn over the soil before planting?

1. Loose soil.

The ploughed land will be looser and thus more breathable, which is conducive to the soil to retain water and oxygen, and create good conditions for the growth of crops.

2. Disinfection and sterilization

Ploughing the field before planting crops can allow the soil to be fully exposed to ultraviolet rays, and the bacteria and pests in it will be killed, which can not only improve the germination rate of seeds, but also reduce the probability of future pests and diseases.

3. Improve fertility.

After deep ploughing, sufficient well-rotted farm manure (or other organic fertilizer) can be applied, which helps the fertilizer to penetrate into the soil, thereby increasing fertility and promoting seed germination and crop growth.

4. Precautions.

1) The depth of ploughing should not exceed 20 cm, because too deep ploughing will not only not bring benefits, but will have a nitrification effect on crops.

2) According to the season and the growth of crops at that time, spring ploughing, summer ploughing, autumn ploughing and winter ploughing should be adopted respectively.

Second, what are the tools for turning the soil?

1. Pickaxe. 1) One end of the hammer is made of iron, and the other end is made of wood, and the iron part has a ring fastened on top of the wooden part.

2) The hammer is often used in rural areas to turn the ground, and when it is used, hold the wooden part with your hand, and then start working. The pickaxe is relatively sharp, so be careful when using it.

2. A shovel. 1) The shovel is in the form of rectangular sheets, made of wrought iron or steel, and a long wooden handle is installed at one end.

2) Shovels are often used by farmers to shovel sand, soil, and other things.

3. a hoe. 1) The hoe is a traditional long-handled agricultural tool and one of the tools commonly used by farmers.

2) The hoe has more functions, and can be used in agricultural activities such as ridge making, ploughing, soil covering, harvesting, digging holes, cultivating, soil cultivation, weeding, and soil breaking.

Answer: Because the turned soil is soft and breathable, rainwater can easily be retained in the soil, and air can also enter the soil, and at the same time, when turning the soil, it can also kill some insects hidden in the soil, so that the seeds sown in it are easy to germinate and grow.

This makes it easier for the seeds to germinate and grow.

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.

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.

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. Reasons.

After a winter of dormancy, the plants are finally entering the peak growing season in the spring, and the most indispensable thing in this season is to repot the bonsai.

2. Steps. 1) In the morning or evening, use wire or small bamboo branches to turn the soil along the edge of the flower pot;

2) When turning the soil, you must pay attention not to get too close to the base of the flower, so as not to hurt the root system;

3. Stop watering two days before turning the soil, otherwise the potting soil will be stuck together due to the water, holding the root system, and it will be strained when turning the soil.

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 soil's water retention capacity will also be improved, and the soil aeration is also improved, which is conducive to the sowing and development of crops. By deep ploughing of the soil, the deep soil can be turned out, and the bacteria and insect eggs can be killed after sun exposure.

Whether it is vegetable planting, fruit tree planting or food crop planting, the soil needs to be deeply cultivated, which is what we often call turning the soil, why do we do this?

Why plough the soil before planting vegetables.

Because deep ploughing of the soil has several good effects, it can improve the growth efficiency of crops and reduce the occurrence of diseases.

First of all, 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 soil's water retention capacity will also be improved, and the soil aeration is also improved, which is conducive to the sowing and development of crops.

Secondly, 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, a lot of germs, insect eggs are stored in the deep soil, if not deep ploughing, the bacteria continue to multiply in the registered soil, which 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 fertilizers, 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.

Deep tillage can bury green manure, crop residues and organic manure applied to the topsoil layer to the lower layer, creating favorable conditions for the survival, reproduction and activity of microorganisms, and accelerating the process of soil maturation.

Through the decomposition and transformation of soil microorganisms, the fertilizer efficiency of organic fertilizer is finally improved and the soil condition is improved.

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, and the upper layer of soil with poor structure can be turned over to the lower layer after deep ploughing.

These soils gradually recover in the deep soils, and are turned over to the top of the soil the following year when they are deeply cultivated, so that the cycle is reversed, which is a kind of protection for the soil and also restores 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.

Time for deep ploughingIn general, the best time is to plough after the crop is harvested, when the stubble from the ground can be turned into the deep soil and become fertilizer after decaying.

The depth of deep ploughingIt is necessary to adapt measures to local conditions, for example, the deep ploughing in arid states should be shallow, and the deep ploughing of saline-alkali land should be relatively deep.
