Is it necessary to plow the ground before planting corn? Is it any use?

Ploughing, for crop cultivation, is a very necessary work before sowing.

Those who have planted the land know that in the mountainous countryside, there is no contiguous land, it is not a scale, it is scattered planting, scattered planting, and rotation is relatively common. Due to the limited land and because the common crops in rural areas are corn, potatoes and sweet potatoes, continuous cropping is common.

Most of the corn is harvested in August and September, and the sowing is in March and April every year, during which some families will sprinkle radishes or plow the corn fields to plant winter vegetables, but most of them will continue to be planted in the next year.

In my hometown, before spring ploughing, the soil is ploughed, called "ploughing the soil", and potatoes, corn, and sweet potatoes are planted. Corn fields from the beginning of the appearance of corn bales to the next year's spring ploughing, the time is as long as 4-6 months, the soil is deposited, at the same time the countryside is fed livestock, in winter will be poles to graze in the field where there are no crops to grow, many corn fields will be trampled, the soil is compact, if you use a hoe.

It is difficult to loosen the soil.

In order to better allow crops to germinate and grow, while keeping the soil loose and breathable, the ground is ploughed before ploughing, and corn is not only ploughed but also harrowed when it is sown. In the past, the ploughing ox was selected to plough the land, and now the ploughing ox is difficult to see, and the rotary tiller replaces the ploughing ox, which is fast, saves time and effort, and can also save the trouble of raising the ploughing cattle.

Rotary tiller ploughing, will be deposited, compact crops land loosened, the depth of each ploughing is generally about 30 cm, can make the whole plot of soil restored to a loose state, due to the loosening of the soil, when the corn is sown, the seeds can effectively contact the soil, so as to quickly germinate and grow seedlings, due to the ploughing after sowing corn, many seeds are on the soil surface, affecting germination, the last process, is "harrowing", many times the rake will put stones to maintain the weight, when I was a child as a stone to sit on the rake, adults harrow the ground, By raking the ground, large pieces of soil can be raked finely, and at the same time, the roots of crops left in the soil last year can be raked out and put aside, which is conducive to the rapid growth of corn seeds.

If not ploughed, the soil is easy to compact in the clayey soil environment of the mountainous area, which is not conducive to the growth of crops, while the sandy soil in the north can effectively penetrate the soil roots.

In short, whether it is corn or other crops, it is necessary to plow and then plow when the land is compact.

Ploughing is required. First, the emergence rate is high and the seedlings are neat. Second, it is conducive to the growth of corn roots and enhances the lodging resistance. Third, there are few weeds and high fertilizer efficiency. Fourth, reduce the occurrence of corn diseases and insect pests.

Yes, ploughing is required; Ploughing can make corn grow very well and increase corn yields.

Therefore, after learning the lesson, it is necessary to cultivate the land before planting corn, and deep ploughing and raking, which has the following benefits:

1. High germination rate and neat germination. Corn is planted on deep soil, which solves the problem of soil compaction and soil ventilation. Such an environment can ensure that the seedlings germinate neatly and have a high germination rate. Seedlings, when the interval between emergence times is large.

2. It is conducive to the growth of corn roots and enhances the lodging resistance. The taproot and fibrous roots of corn are relatively short, and the soil that has been ploughed deep is soft, and the roots of corn are more likely to grow into the ground.

Before planting spring corn, it is best to plow the ground once if possible. Ploughing and then sowing can make the corn grow better, make the corn more effective, and do a better job of pest control.

Corn planting can not tolerate the slightest sloppiness, and the effort we save when planting will be reflected in the growth and harvest of corn. When our family grows corn, we will choose to plow the land, which can bring the following benefits.

Loosening the soil and masking chemical fertilizers help corn grow betterCorn takes root in the soil, and allows itself to grow and grow by absorbing nutrients and water from the soil. Before we renovate the soil, we apply fertilizer to the ground, and when we renovate the soil, the fertilizer is evenly covered into the ground. This method can avoid the volatilization of chemical fertilizers and make the fertilizer effect more uniform.

During the growth process of corn, it also needs surface rainwater to infiltrate into the ground, and the soil also needs to contain an appropriate amount of air, which are all necessary environmental factors for corn growth.

After renovating the soil, it will make the soil clods compact, loose and fine. In this state, the soil will increase the water content and air content, which will help the corn to take root in the soil and extend the root system in the soil.

Turning over the land to reduce weeds and pests and diseases The soil contains all kinds of bacteria and insects, which can pose a threat to the growth of corn. Bacteria cause the entire corn plant to die, while insects directly damage the corn roots, or they can crawl to the ground and gnaw on the corn stalks.

Normally, they are buried deep underground, allowing them to hide from predators. When the soil is turned over, sunlight can kill the bacteria, reducing the bacterial population. Birds, in turn, will renovate the land, looking for tasty, tasty bugs and eating them all.

Without viruses and insects, corn will grow better, and with the right fertilizer efficiency and climate, it will be able to usher in a bumper harvest year.

Based on the above situation, ploughing is a very necessary thing in the process of corn planting, and increasing the ploughing process can make corn grow better.

Before planting corn in spring, you need to plow the land again, so that the corn harvest will be very good, of course, the demand for corn for the land is not particularly strict, and it is okay not to plow it again.

It is still needed, because it helps to improve the degree of soil porosity, can reduce pests and diseases, and reduce the generation of weeds.

Of course, it will be easier in the planting process and will also help with production.

It is not necessary, when you need to plant corn, you can plant it directly, and wheat is generally harvested before and after the Dragon Boat Festival in May every year, and you can plant it directly after harvesting.

Normally yes, but you can also do without it, and if you have to plow the land and need to water it to grow corn, it's more troublesome.

Before planting corn, you need to plow the ground so that the soil is kept loose, which is conducive to the germination of corn seeds and aerobic respiration.

After harvesting the wheat, gradually planting the corn, and without cultivating the machine soil, plant immediately. Criticism, cultivator, is better, sprinkle base fertilizer, cultivator again, soil permeability is good, reduce microbial strains and pathogenic bacteria damage, is conducive to the growth and development of crops.

However, before the corn was planted, there was no agricultural land, and the bud rice was growing well, and the farmers did not use agricultural land, which has its benefits. Soil is made up of soil colloids of different sizes, and the soil particles composed of this soil colloids make up the soil layer of agricultural land.

There is a gap between the particulate matter in the soil layer, that is, because of the existence of the gap, the soil layer has the level of absorption of nutrients and water. In addition, it is mainly because of the existence of gaps that the soil layer can complete the circulation of water commodities and gas exchange inside and outside. However, after a season of agriculture, the soil layer declines to a certain extent due to the functions of farming, human factor management methods, rainfall and other factors, resulting in a narrowing of the gap between the particles of the soil layer.

The main manifestations of the direct soil layer are clay weight, agglomeration, poor air permeability, water barrier, poor soil fixing ability, etc. The cultivator has the benefit of rotary tillage, and the non-tillage machine has the advantage of not rotary tillage. The land resources of the cultivator are widely publicized, and the seedlings are excavated and the rise is abundant.

defects, the soil layer is loose, and the windy corn seedlings should be poured seedlings. If the land resources of the cultivator are planted with buds, the relative cultivator land at the seedling stage rises a little slower, and the buds grow down and take root in the hard soil, and the buds look firmer and resist lodging than the land of the cultivator.

Wang rice belongs to the railing crops, is a monocotyledonous plant, the root system is developed, there are taprhizomes and fibrous root system, the soil layer is loose and there is a gap after planting, and the corn is conducive to rooting and germination after sowing, digesting and absorbing underground nutrients, and growing and developing rapidly. The loose soil layer has strong air permeability, which is beneficial to increase the ground temperature, and the germination rate of bud rice is high, which improves the yield of maize. The growth period of summer maize is shorter, because the competition is more reasonable growth and development time, to prevent the on-time improvement due to the drop in temperature after the beginning of autumn, so it is necessary to sow as early as possible.

It is definitely needed, so that the soil can be more breathable, and at the same time, it can kill bacteria, which is conducive to the growth of plants.

Need. If you don't loosen the soil a little, it will be difficult for corn to grow well.

This needs to be judged according to the actual situation, and there is nothing too certain about this.

Corn needs to be cultivated. Corn in the preparation of the ground before sowing deep turning, the hall sedan slippery foot base fertilizer, it is best to carry out deep ploughing, winter irrigation or spring irrigation before the land in winter. Seeding depth:

The sowing depth is generally 5-6cm. In the clay soil with good soil moisture, it should be sown shallowly, 4-5cm is appropriate. Loose sandy loam soil should be sown appropriately deep, with 6-8cm as appropriate.

If the soil moisture is large, it should not be sown deeply, and the soil should be sown deeply.

Compared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability. Corn has a high nutritional value and is an excellent food crop. As a high-yield grain crop in China, corn is an important feed for animal husbandry, aquaculture, aquaculture, etc., and is also one of the indispensable raw materials for food, medical and health, light industry, chemical industry, etc.

It is really needed, so that the land becomes looser and there is better air when planting.

Yes, because before you plant these things, it will be better to plow it into the ground.

No need to know, after harvesting wheat must be planted corn immediately, it is very important to rush time, there is no rotary tillage bridge buried land, corn hand elimination seeds are easier to combine with the soil tightly, easy to emerge.

Personally, I think that of course it is necessary to rotary tillage, so that the corn will germinate better, and it will grow better, and the yield of corn will be increased.

If the climatic conditions allow the ploughing before sowing, of course, it is more beneficial to plow the land and then sow the seeds.

But farmers don't like to sow corn after ploughing, because the wheat harvest season rushes to harvest and grab seeds, because there is wheat before and after the harvest happens to rain, soil moisture is better and suitable for sowing, so grab seeds, plough after sowing farmers have three fears: one is afraid that the soil moisture content will decrease after plowing, can not keep moisture; Second, I am afraid that the rain will affect the sowing after ploughing, and the third is afraid of increasing the cost and increasing the cost.

So what is the use of sowing after ploughing, I personally think that there are at least the following benefits.

1. Control underground pests and increase organic matter.

Now wheat harvest is with a combine harvester, after harvesting the wheat stubble in the field is very high, the wheat straw is very thick, although it can be sown, but these wheat stubble and wheat straw will become the habitat of underground pests such as Spodoptera exigua, grubs, etc., if these impurities are turned into the ground, and then watered, when the soil moisture content reaches the appropriate level, sowing can not only speed up the decay rate of these impurities, provide the necessary organic matter for the growth of corn, but also can eliminate these underground pests, reduce the harm to seedlings.

Second, it is conducive to cultivating and weeding.

After ploughing and then sowing corn, you can spray a closed herbicide before sowing seedlings, so as to greatly reduce the labor intensity of corn tillage and weeding, even if weeds grow in the later stage, it also saves time and effort in tillage.

Although there are a lot of corn field post-emergence herbicides on the market now, most of the pesticides will be sprayed on these field impurities due to the thick wheat straw and high wheat stubble when used in the field of high wheat stubble, which reduces the efficacy of the herbicide, and the herbicide of the corn field of some weeding fiefdoms will also lose the effect of the fiefdom, and the pesticides infected on the impurities will not be absorbed, and the soil will be polluted with irrigation or rainfall, which will affect the crops under the stubble.

Third, it is conducive to sowing and seedling.

The depth of corn sown in the wheat stubble field is not shallow.

First, the root is shallow, the seedlings are slow, and the seedlings are uneven, which is not conducive to management. However, the biggest advantage of the corn sown after ploughing is that the depth is consistent, the root is deep, the seedlings emerge quickly, the seedlings emerge neatly, the seedlings are robust, and the seedlings are easy to manage.

It is necessary to plow the ground, because it is to loosen the soil, and when the corn grows up, it will not cause the soil to be too hard, so that the corn can develop better.

If necessary, the first is to loosen the soil so that the seeds can take root and germinate, and the other is to plow the ground to plow out the corn roots of last year for easy sowing.

It is necessary. Ploughing will make the land very loose. The corn grown in this way can better absorb nutrients from the field. Even more delicious.
