Is it true that dense corn planting will yield high yields? What is the truth?

The denser the corn is planted, the lower the yield, and the row width and spacing of corn are generally greater than 20 cm, otherwise the corn that grows is very short, or it does not grow corn directly, only grows stalks.

Dense planting of corn will not be high-yielding. The reason is as follows: densely planted corn competes with each other for nutrients, sunlight, water, etc., and if the nutrients can only satisfy a small number of groups, it will only be counterproductive.

No. Because too dense will make the corn unable to absorb enough nutrients, and the gains will outweigh the losses. Scientific planting is best.

China's annual consumption of corn in about 2.7 million tons, corn in the south of our country, the north of the planting area is large, the scope is wide, the main planting area is divided into five characteristic ecological regions, the northern spring sowing corn area, the Huanghuaihai summer sowing corn area, the southwest mountainous corn area of the largest corn cob weight [dry corn cob weight 1 catty], all of a sudden sensation in the whole village, half of the village 50% of the farmers have booked this corn variety. Corn sown on fertile soil, with equal fertilization, no matter what variety is sown, grows better than corn sown on unfertile soil. Corn has thick stalks, hypertrophied leaves, fast growth, large and long ears (cobs), and high yields.

Crops a branch of flowers, all rely on fertilizer to be in charge, do not apply enough fertilizer, want to high yield, that is impossible, now the crops really rely on fertilizer, top dressing more and less, the growth of crops is completely different, densely planted corn must be more fertilizer, to ensure that the nutrition is satisfied, in order to have a bumper harvest. But crops need space to grow on the ground, and there is enough space to receive sunlight for photosynthesis, which is called fighting for heaven and earth. Yield, on the one hand, to increase and stabilize the weight per panicle, on the other hand, to increase the number of plants, increasing the density is the most direct and effective measure to increase the yield.

<>On the other hand, if the land is relatively poor and the water conservancy conditions are poor, the appropriate sparse planting is more stable. There are also according to different corn varieties, the amount of sowing per mu to be planted, some are suitable for dense planting, and some are suitable for sparse planting and large ears, so we must be flexible and master. The plant spacing is generally about 25 cm.

All aspects of high corn yield are important. Fertilizing and watering is also a top priority. You also have to have a good relationship with God.

Floods and continuous rain are the most difficult of the disaster. Farmers have a good harvest and risks coexist. It can be sown in both summer seasons, spring sowing on April 5 before and after Qingming seedlings transplanting, summer sowing rape harvest in mid-May, wheat harvest in early June can be sown.

Select Medium Dense. Because in order to get a high yield of corn, it is necessary to allow the corn to absorb the full range of nutrients. Medium density is the best choice.

Medium density. In this way, the nutrients in the soil are better absorbed, and the fruit-bearing rate can be increased a lot, and dense planting cannot achieve this effect.

Choose medium-dense planting. Because the planting density of corn is too large, there are two disadvantages that cannot be ignored, one is that the absorption of nutrients by the roots becomes poor, resulting in the growth of some plants; Second, the leaves cover each other, and the pollen is not easy to fall on the female spike, resulting in the inability to fertilize and set fruit normally, which not only causes baldness and heavier, but also easily leads to the phenomenon of lack of grain or multiple spikes in the female spike.

Regarding the planting of corn is planted with high dense yield, or planted with high thin yield, this is to pay attention to science, can not be treated by planting dense or thin to determine the yield per mu of corn, it and corn varieties, farmland soil quality, later planting, fertilizer, watering, loosening soil, natural rainfall, climate, temperature. Regarding the sparse planting or intensive planting of corn, I will mainly talk about the following aspects in detail<>

First, when the corn is planted densely, the soil itself is required to be fertile, and the bottom fertilizer should be good, and the varieties suitable for intensive planting should be selected. But it can not be planted too intensively, which will affect the ventilation of corn in the later stage, and it is easy to get mildew rot, which is commonly known as corn grain, which is black and will not grow corn kernels. Excessive intensive planting will also easily cause aphids to multiply in the later stage of corn during flowering, affecting corn pollination and resulting in a decrease in yield.

When the corn grows to 50cm, it is necessary to loosen the soil and water it in time to promote the development of the root system, which can resist the strong wind in the rainy season to a large extent and prevent the lodging of a large area of corn, resulting in unnecessary yield reduction. After entering the rainy season, it is necessary to prevent the occurrence of flood disasters and drain water in time, otherwise the leaves under the corn will be yellowed or even soaked to death. If there is little rain, it is necessary to water it in time, corn is a crop that likes water.

Especially in the later stage of the development period, it is necessary to timely top dressing and watering, which is the most critical time for the whole corn growth cycle, which seriously affects the yield. <>

Second, when corn is planted in a sparse state, it is more suitable for places with poor soil and little rainfall. When carrying out sparse corn planting, it is necessary to choose varieties suitable for sparse planting, drought-tolerant and low-soil requirements. Densely planted corn is generally relatively large in size and has a sweet finished product.

But the yield is certainly not as large as that of intensive cultivation. <>

Third, the intensive planting or sparse planting of corn is mainly due to the low value, according to the actual situation, can not be generalized, if the conditions permit, or intensive planting is good, not let it cause a waste of land resources, virtually affect the output, resulting in a decrease in income, the original agricultural planting has no profit, and even lose money.

Through the above analysis, I hope that the corn is densely planted or sparsely planted relatives have some help, and I will continue to solve problems for you here in the later stage, and strive to do what I can.

Planting corn is moderately dense and has the highest yield, and whether it is too thin or too dense will eventually affect the yield.

It is best to plant corn in rows of seeds, so that the corn can receive enough sunlight, and it is also convenient for us to manage and harvest.

There are certain differences in the cultivation density of corn in different regions, for example, the cultivation density of corn planting in the eastern part of Heilongjiang is affected by climatic factors, and the number of seedlings per mu is about 3400; However, in Jilin and Liaoning, due to the ideal climatic factors, the number of seedlings per hectare is basically maintained at more than 60,000 plants, and the number of seedlings per mu is also more than 4,000 plants.

At the same time, affected by the difference of corn varieties, the cultivation density of different corn varieties in the same area also has certain differences, relatively speaking, the cultivation density of special corn is low, and the cultivation density of conventional corn is larger.

In our northeast region, the ridge width of corn is basically about 55-60 cm, we use the ridge width of 60 cm to calculate how many corn plants can be in the range of 1 square meter when the hole distance is 7 inches? We convert 1 square meter into an extension meter to calculate, i.e. 1 extension meter.

By calculating how many corn plants are in the extended meter, we can calculate the number of seedlings per mu of land in the case of a hole spacing of 7 inches. This is the number of holes in which corn seedlings are planted in 1 extended meter, which is about 8 voids. One acre of land is 667 square meters, and we can use 667 square meters multiplied by 8 empty meters to calculate the number of seedlings in one acre, which is 667 * 8 = 5336 plants.

The number of seedlings per mu is 5,336, which is equivalent to about 80,000 seedlings per hectare, which is a bit too high, right? It is rare to have such a high corn planting density, and the problems of lodging, seed setting rate, and convex tip in the later stage may be more indiscriminately burned. Therefore, it is recommended that you decide whether you need to adjust the planting density according to the actual planting situation and variety in your local area to avoid the adverse effects of blind high-density planting.

The above are some of my views on this issue, if there is anything inappropriate, please Haihan.

Densely planted corn is more productive than sparsely planted corn, but it is also necessary to choose suitable land, after all, corn is a crop that increases the yield of groups.

Not necessarily, because corn is planted too densely, it will have a certain impact, and corn can not absorb nutrients well, but will cause a certain negative impact, and the yield will not be too high.

Growing corn requires a good understanding of the distance between the plants. Dense planting of corn will make the ventilation between corn plants poor, and will also affect growth.

Yes. This is a very good choice, and if you choose this, you will have a very stable income. It is also possible to increase production.

Seeds: If you want to increase corn yield, you need to select seeds with round kernels and soak them in warm boiled water to promote teeth. Planting:

Sprinkle the corn seeds on loosely permeable soil and cover with a layer of agricultural mulch. Fertilization: During the growth period of corn, phosphorus and potassium fertilizers will be applied to it.

Disease prevention: Immediately pull out the diseased corn seedlings.

1. Seed solution.

How to plant corn to increase yield.

In order to increase the yield of corn, it is necessary to select high-quality seeds with round grains and no pests and diseases, and then soak them in warm boiled water at 45 degrees for 24 hours, so that the seeds can digest and absorb sufficient water, improve the seed yield of corn, and then place the corn seeds in the ambient temperature of 29 degrees to carry out tooth promotion.

2. Planting steps.

When planting corn, the seeds must be evenly sown on the surface of the soil, and then irrigated with water, and then covered with a layer of agricultural mulch film to promote the rapid germination of corn, and after the corn germination, the agricultural mulch film should be untied immediately, and the corn seedlings should be replenished and thinned to make it healthy and healthy growth and development.

3. Topdressing fertilizer.

Corn is fertilizer-loving, it can grow and develop poorly in the case of insufficient nutrients, when raising corn, it is necessary to apply fast-acting base fertilizer to it during the main stem seedling period, so that the growth rate of corn is accelerated, and in the abundant growth period of corn, it must be top-applied to phosphorus and potassium as the dominant compound fertilizer, so that the total yield of corn increases. Most growers use their planting experience to determine the variety and amount of fertilizer to be fertilized when fertilizing corn, but that is not scientific and can easily lead to the consumption of chemical fertilizer. Different soils contain different nutrients and the necessary chemical fertilizers for corn species, and if you blindly follow the trend, it will easily lead to soil agglomeration and reduce soil quality.

In order to ensure scientific fertilization, it is necessary to carry out the use of fertilizer to maximize profits according to the fertilizer content of different soils and different types of fertilizer. The key fertilization methods for corn are methodical application, sprinkling application, and hole application. According to scientific research, the actual effect of strip fertilization is the best, because this method can release the fertilizer to the position closest to the root, and more reasonably promote the digestion and absorption of nutrients at the root.

4. Disease prevention.

Corn is very susceptible to brown spot disease, when raising corn, you must observe the growth of the plant on time, if you find that the corn is susceptible to the disease, you need to immediately pull out the diseased seedlings, and according to the instructions for use spray fungicidal drugs, to solve the pathogenic bacteria on the corn, to maintain the normal growth and development of the main stem.

To choose the right variety, before noon to do a good job of seed and seedling work, must do a good job of drainage, should also pay attention to planting density, must turn over the land before planting, must be carefully cared for, do a good job of preventing pests and diseases, to choose scientific fertilization and watering, to choose the soil with better drainage, to harvest in time.

When planting corn, we must grasp the spacing, plant it in a sunny place, and usually water more, fertilize more, remove weeds in the front, and spray pesticides in a timely manner.

It is necessary to choose good corn seeds, and it is necessary to carry out thinning, proper watering, proper fertilization, prevention of pests and diseases, and it is best to enter enough base fertilizer when planting corn.

The current corn varieties are generally hybrids, with spring and summer sowing; There are early and late maturing; There are upright and compact. Therefore, when determining the planting density, it is first necessary to clarify the characteristics of the seeds used. If it is sown in spring, the high-stemmed and late-maturing varieties should be 3000-3200 plants per mu, the medium-stemmed and mature varieties should be 3200-3500 plants per mu, and the short-stemmed and densely planted varieties with compact vertical leaves should be 4500-5000 plants per mu.

The density is generally 4,000-5,000 plants in summer. Regardless of spring sowing and summer sowing, the density should be determined according to the introduced varieties, but you can't make your own blind decision, so as not to affect the yield.

Corn needs more fertilizer in its lifetime, and it absorbs more than 20 kinds of nutrients from the soil, including nitrogen, phosphorus, and potassium. According to the measurement, for every 1,000 catties of corn kernels produced, nitrogen catties (equivalent to 46% urea 50 catties), phosphorus catties (equivalent to 46% diammonium phosphate 17 catties), potassium catties (equivalent to potassium chloride 38 catties) need to be absorbed from the soil. As can be seen from the above data, corn is a food and drink"Pot-bellied man"。

When determining the density, it is necessary to consider the soil level and fertilization capacity, and the natural conditions include natural factors such as light, temperature, and precipitation.

In areas with long sunshine time and large temperature difference between day and night, corn plant respiration consumption is less, water conservancy irrigation conditions are good, precipitation is abundant, and the planting density can be appropriately dense in areas that can meet the water demand of corn at all stages. It should be sparse on the contrary and can differ from the 500 strains that are prevalent. For example, in the summer corn planting in the Huanghuai region, the white axis corn sparse big stick type, which was once the most popular among farmers, has reached the verge of elimination.

The sowing rate of traditional white shaft corn is less than 4,000 grains per mu. Although the rod spike is not small, it has the shortcomings of thick shaft, slow dehydration, not easy to dry, low bulk density, and not conducive to machine harvesting.
