When sowing corn, is it better to choose single or double planting? Why?

Personally, I think it's better to plant two plants, because double plants are easier to grow.

Choose to plant single or double corn, depending on the actual situation; Natural conditions such as land light vary greatly from place to place. Looking at the plot as a whole, if the double corn yield is high, plant two grains of corn, and if the single kernel corn has an advantage, plant a single kernel corn.

Corn double or single planting, should be planted flexibly according to the conditions, planting two corn per hole is more labor-saving, the light conditions need to be better, and the plant spacing should be larger, otherwise it is easy to vegetative growth too much and affect the development of ears. Single-plant cultivation is the most common cultivation method, which is a little labor-intensive but the ontogeny is relatively uniform.

Nutritional value: The vitamin content in corn is very high, 5-10 times that of rice and wheat, and the nutritional value and health care of maize are the highest among all staple foods. The high nutrients such as riboflavin contained in maize are very beneficial to the human body.

I think it is better to choose a single plant, according to the specific soil conditions, according to the variety of selection, so as to better improve the yield.

Two different varieties of corn seeds are mixed together, and the effect can be mixed. Let's take a closer look at the advantages and disadvantages of mixed seed sowing.

1) It is necessary to select maize hybrids that are suitable for local planting and have strong stress resistance, and varieties with distant relatives are more suitable;

2) the growth period of several maize varieties should be close to that of increasing the probability of field hybridization;

3) The color of the grains of several corn varieties should be consistent, so as not to affect the commerciality of the grain.

1) Different varieties of maize will be cross-pollinated, which will affect the yield. What's more, their offspring, F1, has an unstable genetic phenotype, and various production indicators also change significantly.

2) Corn is pollinated by wind, and insects can also pollinate, but manual pollination is troublesome. The male flower is on top and the female flower is in the middle. In order to breed new varieties, artificial pollination is allowed, which is not necessary for normal growth. If it is not done well, it will reduce the yield.

3. Varieties with strong resistance and varieties with weak resistance need different fertilizers. If mixed varieties have the same level of fertilizer requirements, they may not meet the nutrient needs of both parties. High yields are high for high-yielding varieties and low yields for low-yielding varieties, and low yields will affect the total yield.

Even if two varieties have the same maturity and yield, the same fertilizer requirements cannot meet the nutritional needs of both parties. The inevitable result of "competition for fertilizer" between varieties is that the weak are inferior. The original good advantages cannot be brought into play, and the output will naturally not be very high.

Therefore, it is not advisable to plant different varieties of maize in the same field.

This effect is very unpleasant, because mixing two varieties together may produce hybrids.

Yes, it will be fine, but it depends on the specific situation to make a practical judgment.

Don't do that, because you might be very confused when the time comes to harvest the corn

The effect is not good because genetic mutations may occur. The result is unknown to anyone.

Corn varieties are divided into early-maturing, medium-maturing and late-maturing varieties, with a growth period of about 80 120 days, compact, loose, and plant height of about 100 150 cm, and individual varieties exceeding 200 cm. Corn seed blending is now not well supported by science and is not advocated by agricultural experts. However, there is such a peasant proverb:

Experience is learning. Experience is the crystallization of wisdom summarized in years of planting and production. The height is about the same.

This is how I sow corn, that is, I put two equivalent corn seeds into a funnel, and the corn that comes out is a variety in the next row, which is better than the blended corn seeds, which is troublesome and the effect is not as uniform as this.

If it is a lack of seedlings and a small amount of planting is understandable, if it is a large area of corn planting, I advise in these words, do not blindly mix, the characteristics of the root hybrid corn, and the difference in the growth cycle of corn, the probability of blending and sowing to reduce the yield is far greater than the increase in yield. Mixing two different corn seeds together can increase yields. This was true forty years ago.

In the 60s and 70s, we planted experimental fields in our village, and I personally participated in such experimental work at that time. That kind of test is called:

Cross-pollination, interlacing to Tiansui, and artificial pollination, etc.

We will mix more than two varieties of corn together, and in the future, when the corn is pollinated, the original characteristics will have to be changed, because the corn can be cross-pollinated and produce another variety, so it is not necessarily good or bad. If there are not enough corn seeds, it is not worth buying a whole bag, and the east neighbor will have a handful left, and the west neighbor will make up a handful and plant the land. After the emergence of seedlings, due to various reasons, incomplete seedlings, replanting, borrowing seedlings from neighbors' fields for transplanting, and finally, there are no less than 4 or 5 varieties in the corn field, which are varied.

In the planting process, due to the different ways of mixing, the yield increase effect is also different. For example, two varieties of corn are mixed and sown, so that the same plot can not be separated from the two varieties without interlaced sowing and the yield is high.

Different corn varieties cannot be planted together, because the corn varieties are different, then its maturity period is different, and there will be a phenomenon that one corn variety is ripe and the other corn is not ripe.

It is possible to grow together, and attention should be paid to the density, but also to the growth and development of some varieties, as they may have some accidents.

Yes, but these two different varieties are certainly not very convenient to manage, and the amount of fertilizer and watering that needs to be applied is not the same.

Corn, also known as bud valley in Northeast China, belongs to the grass family, native to Central and South America, now all over the world are planted and dressed, it is an important food and feed crop in the world, because it is rich in protein and other nutrients, also known as "longevity food". Corn is an annual herbaceous plant, which is widely cultivated in many areas, especially in mountainous areas, and brings good income to farmers. So how should corn be grown?

Corn grows in tropical and temperate regions, has certain requirements for heat and moisture, the whole growth period requires a higher temperature, seed germination temperature of six to ten degrees Celsius, suitable for growth temperature is twenty-eight to thirty degrees, corn can tolerate low temperature, flowering temperature requirements of more than twenty-five degrees. There are different varieties of corn in China, which are early and late maturing, and their growth characteristics are different.

Is it better to plant corn with a single or double tree? In our northern region, corn planting is a hole with two grains, planting to be artificially planted, but also to cultivate soil, and then covered with plastic mulch, can play a good thermal insulation effect. After the corn seedlings emerge, the seedlings should be released, that is, the corn seedlings are pulled out of the plastic film by hand, and then the soil is cultivated and fertilized around.

When the corn grows to two or three leaves, then it is necessary to start hoeing the seedlings, that is, to see if the corn seedlings are all out, if there are two corn seedlings, it is necessary to remove a weaker growth, the purpose is to save growth space, and the corn growth needs to save water and nutrients, a seedling to produce corn must be much larger than two trees, and two grains in a hole when sowing is to ensure the germination rate.

Corn planting is not finished here, this is only its seedling stage, corn still needs to go through the ear stage and the grain stage. The corn ear stage is a critical stage, because at this time the corn has the simultaneous growth and reproduction, which is what we often call jointing, which is the most vigorous period of corn growth, to ensure that the corn is fertilized and watered, and it will pass the critical period smoothly.

When the ears of corn are yellow, and there are still seven or eight green leaves on the plant, it is ready for harvest. In general, it is recommended that you plant corn with two grains in one hole, and then keep one tree to grow best, so that the yield per plant may be the highest, if you want to increase the yield of corn, you can also double the growth of fiber, but the yield is not so high relative to a single plant. I am Xiao Li, who pays attention to agriculture, supports rural areas, and cares for farmers.

For seedling transplanting and live broadcasting, farmers like the most live broadcasting, because live broadcasting saves labor and labor, while seedling transplanting is tiring. In the south, rape is to be planted in October, but in October, the rice in the field has not yet been harvested, but the rape is planted again, what should I do? First, the rape is placed in a small open field for seedlings to be raised, and when the rice is harvested and the farmland is free, the rape can be planted in the field.

It's the same with corn.

First, the direct sowing method of corn.

The corn direct planting method is to dig a pit or ditch with a hoe in the loose soil, and then apply foot fertilizer or sprinkle a piece of farmhouse fertilizer, throw two or three corn seeds in each pit, and then cover it with soil. This operation is very simple, and the process is not complicated. However, it is necessary that the soil has enough moisture for the seeds to germinate.

The disadvantage is that the germination rate of seeds is not very high, and some of the soil covered is uneven and too thick, the lower the germination rate of seeds, which causes waste of seeds, and is easy to get pests and diseases. But then again, in the course of its growth, if it is properly managed, its yield will still be quite high in the future.

Second, the way of corn seedling transplanting.

Corn seedling transplanting is not very popular in our side, because many farmers are afraid of trouble. Corn seedling transplanting is to raise seedlings by putting seeds in the seedling bed, in order to have a seed teething rate of up to 90%, some also buy film, cover the seedbed seeds with film, so artificial needs, film money and more expenditure, some farmers are unwilling to do, but this can better ensure the germination survival rate. In addition, it is necessary to wait a few days for the seeds to open up and produce 2 to 3 leaves before transplanting.

Although seedling transplanting is troublesome, the yield is higher than that of direct seeding, and the advantages of seedling transplanting are easy to survive, reduce pests and diseases, and at the same time provide the nutrients needed for the early growth of corn kernels, saving a lot of seeds. All in all, whether it is direct seeding or seedling transplanting, corn has its own advantages and disadvantages, just look at your own choice, according to the local soil, climate and your own conditions to decide.

Seedlings are better planted. I remember when I was a child, my family was all seedlings and corn planting.

There are many varieties of corn that are distributed in various regions. Depending on the variety of corn, the final harvest results are also different. Although different regions grow different varieties of corn, different varieties of corn can be grown on the same farmland.

Let's learn the advantages of different corn varieties for branch sowing now!

Under the condition that the flowering period is satisfied, the quality and yield of different varieties of maize can be improved through natural hybridization.

Corn hybrids differ from an increase or decrease in yield, which is determined by the characteristics of both varieties. For example, resistant varieties and weakly resistant varieties require different fertilizers. If mixed varieties have the same level of fertilizer requirements, they may not be able to meet the nutrient needs of both at the same time.

High yields are high yields for high-yielding varieties and low yields for low-yielding varieties, and low yields affect total yields, and even if both varieties have the same maturity and yield, the same fertilizer requirements cannot meet the nutritional needs of both parties.

Second, different varieties, the inevitable result of "fertilizer competition" between varieties is a weak disadvantage, the original good advantages can not be played, the yield will not be very high, and the total output will not be very high. In terms of resistance to pests and diseases, mixed sowing can reduce the damage of pests and diseases, increase and stabilize the yield to a certain extent. However, varieties with weak disease resistance have strong disease resistance to various infectious diseases, and this disease resistance may not be lost.

Therefore, it is not recommended to grow multiple corn varieties on the same plot.

Corn is divided into spring corn and autumn corn according to the time of planting. Spring corn is sown at the end of April and early May, and harvested at the end of August. In autumn, corn should be sown no later than mid-July and harvested in late October.

According to the morphological, reproductive and physiological characteristics of maize, the whole life cycle of maize is divided into several different stages. Each stage includes a different reproductive stage, each with its own characteristics and a close relationship with each other.

It must be bad, because if you wear it together, then you can't tell if there is a good or bad quality in it.

I don't think it will work very well, so it's better not to do it.

In fact, the effect is not good, so that the two varieties will live in competition with each other.

I don't think it works very well, because it's easy to get mixed up.

The effect is still very good, and the corn grows big and round.

It must not be good, and the crops may not be good.

I think there are still some unwise illusions about such an approach.

I think it's pretty good, don't you think that's the case?

From the perspective of today's corn cultivation technology, a single seedling sparse planting has already been completed, if two seeds are sown at a time, it can only be too much under today's planting density, and the high density will cause corn to resist diseases and lodging resistance, and the ability to work will be weakened, which is not good for increasing yield. If you want to increase the yield of corn, the cultivation technology must be closely followed, such as applying several times of chemical fertilizer during the period from the corn flare stage to the full bloom and pollination, and even water injection in the second half of the corn perfection, which can bring very good yield increase effect.

However, from the corn planting situation of the pot friends next to him in recent years, it seems that most of the base fertilizer is done at the beginning of corn sowing, and 1 mu of corn organic compound fertilizer is used for 100 catties, and there is very little top dressing in the middle and late stages. In key corn producing areas or some farmers, in order to achieve corn per acre output value, top dressing may still be carried out in the middle and late stages. For example, a friend once said that in the corn trumpet stage, the application of human and animal fertilizer or compound fertilizer, the use of high potassium fertilizer in the middle and late stages of planting, and the yield of other growers is high, in fact, it is the actual effect of top dressing in the middle and late stages.

First of all, after the corn is planted, if the soil moisture is not good, it should be watered immediately. Improve the germination rate of corn and its corn seedlings are vigorous. Secondly, in the case of corn rising waist deep, top dressing should be carried out immediately, and special compound fertilizer for corn can also be used with sodium chloride compound fertilizer!

1 acre of land 80 pounds, at the same time, according to the leaves spray a pesticide fungicide, insecticide, potassium dihydrogen phosphate, medium and trace element fertilizer (the selection of chelated state is more appropriate)! Thirdly, in the corn flare stage, you can apply urea solution again, and 1 acre of land is about 20 catties!

At present, the best machine sowing or single seed seeding has not yet achieved double seed sowing for the time being. If you want to double plants, you must sow one seed by hand on the premise of sowing a single seed, which is a more cumbersome task. Or directly sowing seeds manually, two grains and one hole, and there are many fields, which is unrealistic.

Therefore, whether in terms of nutrient distribution, rhizome condition, or sowing problems, single seed sowing may have advantages over double seeding. In terms of yield per acre, there is no more data to confirm that double maize is more productive than single maize.
