Why do farmers plough the land before sowing seeds?

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.

Because the seeds germinate, it takes threeNecessaryFactor. The first one is the right temperature. The second is to ensure a humid environment.

The third is to have plenty of air. And the farmer's uncle always uses the land before sowing the seedsShovelsFlip it over. It's to make the land more loose.

In this way, the roots of different plants can breathe well in the land. In order to ensure the normal and good growth of crops. After ploughing the soil, it is also more conducive to fertilization.

Good for watering. Cultivated land. For fertilizer distribution, as well as water seepage, the permeability will be greatly improved.

This ensures that the survival rate of the seeds is higher. It can also ensure that the harvest will be good in the future. Why do farmers follow the land before planting?

I have the following points.

Meet the three elements of seed germination, so that seeds can germinate better. I have studied biology in junior high school, and I know that in short, what are the three elements of germination? As I mentioned above, seed germination will only increase if these three elements are met.

Farmers must plant crops in order for the seeds to germinate and grow, so plough the land before sowing the seeds. will make it easier for the seeds to germinate. Let the farmers worry a little.

This is also after a long farming culture.

The experience that has been explored.

In the later stage, it will be more convenient and effective to fertilize and water. In short, after growing small, it is necessary to water frequently. Fertilize frequently.

In this way, their growth rate can be guaranteed. and the quality of their blossoming and fruiting. Ploughing the soil before sowing is crucial for this step.

Watering the ploughed land makes it easier to penetrate into the roots below, so there is no need to water more, and water resources are also saved. During the fertilization process, the soil is also better integrated with the fertilizer, which is more convenient for crops to absorb.

Some compacted soil clods can be broken up to facilitate the growth of plant roots. For plants, the root system is their blood vessels. The more developed their root system is, the denser the plant will grow. The growth rate will also be faster and healthier.

The main reason is that the ground will become loose after being ploughed first, which is conducive to the germination and rooting of seeds.

This is to loosen the soil, allow the seeds to emerge better, and turn the insects or other harmful substances in the soil under the sun to disinfect and sterilize.

In recent years, with the decline of grain, how to save costs and increase efficiency in agricultural production has become a hot topic. At the same time, the no-till planting technology of corn began to be gradually promoted. Indeed, the cost of land preparation is saved.

What about efficiency? I didn't see it. On our side, we finished harvesting wheat and started planting corn, and we didn't spin the soil

Direct seeding. Say, rotary tillage, is the best, sprinkle the bottom fertilizer, rotary tillage, good soil permeability, reduce the harm of microorganisms and germs, conducive to the future growth of crops.

Regarding the question raised by the subject, before corn sowing, does the land need rotary tillage, Wei Nong thinks that the way of doing things is different in different places, and the time of corn sowing is not the same, so it is better to treat it differently according to the specific situation. Weinong wants to combine the corn planted in our Xianyang area before sowing, the land rotary tillage or no rotary tillage, can be, each has its own advantages and disadvantages. You can choose according to your own planting habits, and it has little to do with corn yield.

Let's talk about the pros and cons of rotary tillage and the former Mengtong without rotary tillage.

Summer-sown corn is mostly planted with iron stubble, and no land rotation is carried out. The perennial production practice proves that: 1. The earlier the summer corn is sown, the higher the yield; 2. If summer-sown corn is sown after spinning, the probability of corn lodging is greater.

If the corn is sown on the land without rotary tillage, the seedling stage is slower than that of the rotary tillage plot, and the corn grows up, and the roots are rooted in the hard soil, and the corn grows more firmly and is more resistant to lodging than the rotary tillage plot.

According to the traditional planting method, each crop should be deeply cultivated before planting. We have a saying that "ploughing is deep and early, crops are good", but in actual operation, not before planting to deep ploughing or rotary tillage once, China's corn cultivation is more extensive, for example, the weather in June is now the summer corn planting period after the wheat harvest in the central and southern regions, some plots belong to the valley or hillside, the machinery is not good, the possibility of rotary tillage is relatively small, it is very advanced, for farmers in dry farming areas, it is no less than a conventional planting technology innovation, It will definitely be sought after and used by more farmer friends; Now, no-till sowing of maize has been widely promoted in rural areas in many places.

This makes the soil softer and easier for the fertilizer to absorb faster, which is very good.

The reason for this is that the soil can be loosened, and the loosening soil can better allow the plants to grow, which can increase the yield.

Because the soil is particularly hard before planting, it is necessary to plow the land first in order for the seeds to grow better after sowing.

The advantage of using the Earth Gengu is that you can apply various chemical fertilizers to the crushed wheat straw, wheat bran, and weeds, which can make the land softer. At the same time, there are no weeds, wheat straw, etc. on the surface, so it can effectively prevent the occurrence of pests in the corn field, and at the same time, it can also have more effective growth time, because the temperature will drop after autumn and affect the maturity of crops. Therefore, it is necessary to sow as early as possible, and the earlier the corn is sown in the summer, the better.

The reason for arable land is to make the land softer, so that the air permeability and water absorption of the land will become very good, which is also conducive to the growth and maturity of crops. Only after arriving the land can it be worked, so that the grain can grow and the yield will be higher, because the soft soil is conducive to the growth of crops. <>

When planting in rural areas, some soil will be alkalized after a long time, so arable land is needed. Dig a deep trench first, turn the surface soil into the trench, and dig back and forth on the deep soil to the surface to make the soil more soft and moist. This is a good improvement for the land, so that crops can grow better in this field.

Because there will be a hard half section under some soils, which is not suitable for the deep root system of plants, and some soils are not planted for a long time, and long-term application of chemical fertilizers and pesticides will cause microbial reduction to the land, and the number of diseases and insects in the soil will increase, so it will lead to soil compaction or serious acidification, which is not conducive to plant growth, so farmers must plow the land before sowing. <>

In the past, the countryside used to plough the land, although the soil is simple, but now there are high-tech tractors to plough the land, which will make the soil deeper ploughing, so the yield of crops will also increase, which has a lot to do with the change of soil. Because soil improvement must be carried out before sowing, and only soil improvement will maximize the value of the soil.

Because if the land is plowed first, the land can be softer, and sprinkling bottom fertilizer can make the soil breathable, reduce the damage of germs, and allow the fertilizer to be absorbed faster, which is conducive to the growth of crops.

The reason why we need to plow the land first is because it can better loosen the soil, and it can also allow nutrients to enter the soil to help the acid-base balance of the soil, and increase planting.

It can reduce microorganisms, remove germs, and sprinkle some fertilizer appropriately, which can ensure the air permeability of the soil.

<> the question of whether the land can be deeply cultivated before wheat sowing has been very hot in recent years, and some experts have proposed no-tillage sowing, thinking that deep tillage is not beneficial to the growth of wheat. In fact, it is a common phenomenon for wheat sowers to stop deep ploughing, and it is also the practice of most people, who usually plough the land after the corn and soybean harvest and before the wheat is sown. So what's the reason for this?

What do you need to pay attention to when cultivating the land? Let's find out.

Why plough the land before wheat planting?

1. Avoid soil compaction, no water absorption and no moisture protection, if the land is not deep for many years, the soil is easy to present the above three situations, and in the future planting management process, if close to the upper layer of a few centimeters of soil layer, can not ensure the normal growth of crops.

2. In order to ensure that soil fertility is fully applied, if this step of deep ploughing is avoided, when sowing wheat, the application of chemical fertilizer can only ensure that the ** of about 5cm on the surface can play a role. Further down the soil layer, the ability to absorb chemical fertilizers is greatly reduced, and it cannot provide crops with normal maintenance needs.

3. If you do not plough the land and directly stop wheat sowing, it is easy to be affected by the stalk problem of some crops such as corn, resulting in slow growth of wheat and poor root system, so that the phenomenon of yellow seedlings and dead seedlings will appear. At the same time, not ploughing the land will also aggravate the breeding of pests and diseases.

Precautions for deep ploughing the ground before wheat sowing.

1. Sooner rather than later.

In general, in the suspension of soil deep ploughing, it is necessary to stop it as soon as possible after the harvest of the last crops, especially the plots where the stalks are returned to the field, which can effectively reduce the impact of stalks. In addition, in order to protect moisture and sow wheat, the length of drying time needs to be determined according to soil moisture.

2. Separate ploughing and raking.

The separation of the ploughing and harrow is the separation of the cultivated land and the rake land, and the land is deeply cultivated, and then the harrow operation can be stopped. This ensures that there are no large soil clods in the field, and at the same time, it is also conducive to the preservation of farmland moisture.

3. The cultivated land should be compacted.

The plots of ploughing often show the phenomenon of deep sowing of weak seedlings, lack of seedlings and broken ridges, so after ploughing, the harrowing is stopped, which is conducive to the growth of wheat.

4. The stalks can be watered or nitrogen fertilized.

The key point to pay attention to in the demand of the plot of straw returning to the field is to accelerate the rapid decay of the straw, which can be watered once after deep ploughing, or some nitrogen fertilizer can be applied, which is also conducive to supplementing the nutrients consumed.

Bamboo germination needs loose ants to make the land, so that they can breathe well in the rockless land to absorb nutrients, and after ploughing the stuffy land, the fertilizer can be better distributed and the seeds can absorb the fertilizer.
