Is the plant spacing of corn dense and high yielding? Or is it thin and high yielding?

Of course, the distance is larger, the yield is higher, the main reason is that the planting is more dense, its light, soil fertility, and ventilation will be affected.

Based on the actual situation, if the conditions of the land such as fertilizer and water can be satisfied, it can be planted at a high density. It depends on the actual situation.

<> Is the plant spacing of corn dense for high yield or thin for high yield? Why? Corn plant spacing is the highest yield of reasonable dense planting.

Corn is divided into compact corn and flat corn, compact corn plant type, leaf upstroke, small footprint, suitable for dense planting, 4500 plants per mu is the most suitable. Flattened corn plant type is loose, the leaves are flat, the area is large, suitable for sparse planting, and 3500 plants per mu are the most suitable. The main varieties of compact corn are Zhengdan 958, Denghai 605, Denghai 618 and so on.

The main flat corn variety is Linong 386. This issue should be considered in combination with many factors. For example, factors such as variety characteristics, soil fertility conditions, local water conservancy conditions, and climatic conditions have a certain impact on the target yield.

The summer-sown maize in the Huang-Huai-Hai Plain is taken as an example.

In terms of variety characteristics, generally the varieties with up-punch leaves were more suitable for dense planting, and the varieties with flat leaves were more suitable for sparse planting. Varieties with small spikelets were more suitable for dense planting, and varieties with large spikelets were more suitable for sparse planting. Varieties with short plants are more suitable for dense planting, and varieties with tall plants are more suitable for sparse planting. Varieties with hard stems and strong lodging resistance were more suitable for dense planting, while varieties with poor lodging resistance were more suitable for sparse planting. Varieties with high photosynthetic utilization efficiency are more suitable for dense planting, and varieties with low photosynthetic utilization efficiency are more suitable for sparse planting. In terms of soil conditions, plots with thin soil and low organic matter content are more suitable for dense planting, and the yield is guaranteed by density. Sandy loam soil with poor fertilizer and water retention capacity is more suitable for dense planting, and small spikelet varieties are selected to ensure full grains, and loam soil blocks with strong fertilizer and water retention capacity are more suitable for sparse planting, so as to increase the number of grains per spike and the proportion of grains to promote yield, etc.

As far as water conservancy conditions are concerned, the water-irrigated fields with sufficient water source guarantee and convenient drainage and irrigation can be moderately densely planted, while the dry fields without water source guarantee are suitable for sparse planting to ensure normal maturity. Of course, this is only a general situation and should not be generalized. In addition to the above conditions before selection, it is necessary to carefully read the instructions on the packaging bag to find out the characteristics of the varieties and determine whether they meet their own requirements to ensure the target yield.

Another important thing to note is not to blindly follow the advice of seed dealers.

It will not be high-yielding, and only reasonable dense planting can be high-yielding. If the plant spacing is too dense, the number of grains per ear of corn will be reduced, and if the plant spacing is too thin, the total number of ears will be too small, which will lead to too little yield.

In fact, if it is too dense, the nutrients of corn will not be well released and absorbed, and in this case, the corn will have a low yield.

When planting corn, the plant spacing of corn should be reasonably arranged, and the corn plant spacing is too dense and will cause the size of corn to become smaller. Planting too wide spacing can also lead to wasted land.

It must be planted with high yields, because if the density is high, it is easy to produce some pests and diseases, resulting in poor growth of corn, and the yield will not be very high.

The yield of the sparse seed will be higher, and a certain distance should be maintained, so that the corn will have a very good development environment.

I think it's because the seed is dense and has a high yield, because it can have a good growing environment.

Whether it is better to plant corn is thin or dense is usually based on the comprehensive consideration of planting methods, varieties and soil fertility, so that the maximum value of corn yield can be optimized among the three elements of ear number, ear grain number and grain weight.

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.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Personally, I think it's better to grow honey, so that the yield will be high, and if it is thin, the yield will be reduced.

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.

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.

Planting corn will always encounter the situation of bract rice seedlings breaking in the thresher credit card type, although the seedlings will be replenished, but the relative density is certainly not as high as before. This corn cob will be larger than the average corn cob, and the seeds will be more rounded, but the number is small, so the overall yield will not be higher than that of dense seeds. The soil environment includes many factors such as sun, moisture, fertilizer efficiency level, etc., which will affect the growth of corn, so the soil environment should also be considered when considering the relative planting density.

Generally speaking, the soil organic matter is relatively high, the sunshine time is long, and the temperature difference between day and night is large, and it is <>

Farmers in areas with abundant water sources and more refined management methods are suitable for increasing planting densities, and conversely reducing planting densities for the same species. The growth of corn must have a certain number of plants, sufficient sunlight, fertilizer and water, suitable temperature and humidity, etc., and prevent seedling senescence and disease hazards, etc., in order to ensure the increase of yield. If the planting is too dense, the panicle is small, and the disease is high, and the seedlings are easy to fall in the middle and late stages, especially in the railing rod species. If it is too thin, there will be less spikes, which will also harm the yield, especially in the varieties with small spikes and large densities.

Crops are generally columnar and tight and <> when planted

Dwarf stalks, the species with a short growth period can be moderately sparsely planted, on the contrary, the sparse value should be sparse, the general spring corn is denser than the summer maize, the fields with low soil organic matter should be sparsely planted, and the fields with high fertility can be moderately sparsely planted. In fact, it seems that the vertical impeller shape is an early-maturing corn species, and the density tolerance of this corn is more appropriate, and the vertical impeller shape corn leaves grow upwards and the plant shape is compact. Generally, 4,500 plants are planted on one acre.

Flat late-maturing corn seeds, this corn variety has a poor density tolerance. Generally, 3,200 plants are planted per acre, because the seeds of this type of corn are very tall, the leaves are spacious, and the intersection angle of the ear position and the branch stem is very large.

In addition, there are corn seeds in between, and the density tolerance of this corn species is relatively moderate, and 3,500 plants can be planted in general. Although the sparse bract rice is sparse, the spike is large and the yield is high. The sparsely sown buds are always kept in a row of two and a half feet to one width, and the distance between the plants is nine inches.

The sparsely sown corn stalks are thick and wide, which is conducive to natural ventilation and light transmittance. The fibrous roots are firmly entrenched, and there is very little rubbing with the adjacent fibrous roots, and the nutrient content of liquid fertilizer is not disputed with each other. At the same time, the sparsely sown bud rice is integrated into the pollination and booting stage, and the topdressing of farmhouse fertilizer can fill the lack of phosphorus and potassium fertilizer in the middle and late stages, ensure the longevity of the plant in the middle and late stages, and the rod ears and grains are not bald, full, and compacted.

Any corn variety should be planted in accordance with the requirements of the corn variety, which is the most suitable for increasing the yield to achieve the optimum, because all the corn varieties that have been promoted and planted through the national examination are mostly excellent varieties with high yield and stable yield obtained after many repeated planting experiments. The degree of soil fertility determines whether the planting density is sparse or dense, fertile fields, corn grows robustly, has the potential to bear big sticks, should be appropriately sparsely planted, the lower limit of appropriate planting density is adopted, the soil is less fertile in the field, even if it is sparsely planted, the rod spike is not large, the planting density can be appropriately increased, and the upper limit of suitable planting density is used to plant. At the same time, fertilizer and water management should be strengthened, which can help to improve yield.

It should be determined according to the specific seed situation, and the density of different varieties is not the same, and there will generally be relevant instructions.

It is better to plant corn a little thinner, which can increase ventilation and photosynthesis, which is conducive to the absorption of nutrients by corn; The density of corn is about 4,000 plants per acre, but it is most suitable.
