Which places in China are suitable for growing corn, and what are the precautions for planting corn?

There are many places where corn is planted in China, especially in the northeast region of China, and some of them should be mainly in the northern region, which does not have particularly high requirements for soil qualityAs long as the moisture content of the soil is sufficient, and then there are some basic trace elements, it will be fine. <>

Corn is also a product of high wood yield, if it is planted peanuts and soybeans and the like, it may be hundreds of catties, but if the variety of corn is well managed properly, it is no problem to reach about 1000 catties per mu, although his market is not so high, but this is the basic feed that many livestock are raised, whether it is pigs, cattle and sheep or many other families need it as the most basic food,Even in the war years, it was regarded as an important food reserve, and people could eat it. The planting itself is not too difficult. <>

If there are requirements, it may be that he has a certain thickness of the soil, he needs the thickness of the soil is relatively large, if the bottom is full of stones, it is easy to leak, especially where the soil does not contain water, the growth of corn will be very slow, or the corn will not grow, because its own root system is not developed, every year in the autumn, the grain is received home, to cut down the corn stalks, if you look closely, you find that the rhizome is about the size of a fist, Therefore, such a small rhizome, its ability to absorb water is very limited, unlike some trees, its roots can be extended to several meters a year, or even a few tens of meters. <>

He himself has no other requirements except for soil moisture, but the selection of varieties is still crucial, choose a good variety, the same soil, it can contact more corn, if the variety is wrong, or the quality of this seed is problematic, the yield per mu may drop by 20% or even 30%, this is a very common thing. Generally speaking, experienced farmers have a fixed purchase channel.

The planting area of corn in China is about 42 million hectares, and the planting area is also very extensive: from Hainan Island in the south; north to Heihe, Heilongjiang; from Taiwan and the coastal provinces in the east; As far west as Xinjiang and the Qinghai-Tibet Plateau, corn can be found in almost all parts of the country. There are spring maize in Northeast China and North China; Huanghuaihai has summer corn; There is autumn maize in the Yangtze River basin; Hainan and Guangxi can sow winter corn.

The corn planting areas are mainly concentrated in the northeast, north and southwest. The provinces with the largest planting area mainly include: Heilongjiang, Jilin, Liaoning, Hebei, Henan, Shandong and Sichuan, corresponding to the three main corn producing areas.

Planting corn needs to pay attention to: 1. Select the seeds once before sowing, remove the flat grains and large grains, and try to make the seed size consistent. 2. The spring is windy and easy to run moisture, so it is necessary to grasp the appropriate sowing depth according to the moisture.

3. Check the sowing quality at the beginning of sowing. 4. After sowing, it should be suppressed in time, the soil is too weak, one is serious moisture, and the other is that it can cause weak seedlings. 5. If there is a lack of seedlings after emergence, it is not advisable to supplement the seedlings, and it is best to borrow seedlings.

6. Pay attention to the distance between planting and fertilizer. 7. Prevention and control of underground pests.

Corn cultivation in China is mainly in the northeast, and the south accounts for a minority. Corn is not strict in terms of soil conditions and can be grown on a variety of soils. However, it is most suitable for planting with deep soil layer, good structure, high fertility level, rich nutrition, loose aeration, easy storage and drainage, close to neutral, and coordinated water, fertilizer, gas and heat.

The north of our country is particularly suitable for growing corn, especially in the northeast and northwest, where there are large areas of corn planting. The planting of corn is mainly to select a good corn seed, and then hoe and water regularly, especially in the later stage, especially the watering should pay attention to the weather, not blow the lodging, and the lodging harvest is more troublesome.

In my impression, the northern region of China is suitable for growing corn, and the concentrated production areas include the Yellow River, the Huai River and Shandong, Henan and Hebei in the middle and lower reaches of the Haihe River Basin.

Because corn does not have high soil requirements, most of our country is planted with kernel coatings. Secondly, there are generally not too many requirements for corn growth, as long as the moisture of the soil is guaranteed, but we still need to pay attention to choosing suitable corn varieties for planting according to different soils.

The north of our country is suitable for planting corn, planting corn needs to pay attention to fertilization, irrigation, sufficient fertilizer is the main factor for corn growth, fertilizer is rich in nutrients, and water irrigation is also indispensable for corn planting.

At present, it is possible to plant corn, and it is also a suitable time for planting corn, so let's introduce the suitable time and planting method for planting corn, which can be used as a reference application for you to sow corn. First, the planting time of corn corn according to the different planting time of spring corn and autumn corn, spring corn in late April and early May, can be harvested in late August. Autumn maize should be sown no later than mid-July and harvested in mid-to-late October.

In the life of maize, according to morphological characteristics, fertility characteristics and physiological characteristics, it can be divided into several different growth stages, each stage includes different growth periods, and these different stages and periods have their own characteristics and are closely related. Second, the planting method of corn 1Seed treatment:

After sun-dried corn seeds, they absorb water quickly, germinate early, emerge neatly, have a high seedling emergence rate, and have strong seedlings. 2.Soaking and dressing:

The main purpose of soaking seeds in water is to provide water and promote germination. Chemical soaking mainly includes potassium dihydrogen phosphate and trace elements, but the concentration of soaking is too high or the soaking time is too long, the seeds are easy to be poisoned and damaged, and the germination rate is reduced. Seed dressing with pesticides can prevent and control pests and diseases.

Seed coating is to coat the seeds with a layer of chemicals. Coated seeds have the ability to resist diseases, insects and promote rooting and germination after sowing, and should be treated symptomatically according to local pests and diseases. 3.

An important part of pre-sowing moisture preparation is the adjustment of soil moisture. In the Huang-Huai summer and intercropping summer maize areas, seasonal drought often occurred after wheat harvest, which worsened the moisture of maize during sowing. Therefore, wheat yellow water is often used in production to supplement the bottom moisture. 4.

Reasonable dense planting: reasonable density should consider the characteristics of the variety. Secondly, if the soil fertility and fertilizer application amount are large and reasonable, the appropriate density will be large.

In areas prone to drought and without irrigation, planting densities should be sparse. 5.Calculation of seeding amount:

Seed dosage (kg) Sowing density Number of grains per hole Grain weight Area. Emphasis should be placed on the development of corn precision sowing technology and the improvement of sowing quality. 6.

Sowing depth: The sowing depth is generally 5-6cm. In the clay with good moisture, it should be sown shallowly, with 4-5cm as 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. 7.

Post-sowing suppression: After sowing soil covering, it should be properly suppressed, and it should be heavily suppressed in drought, and when the soil moisture is excessive, it should not be suppressed. 8.

Suitable seed fertilizer: Appropriate application of seed fertilizer can provide sufficient nutrients for seedlings, promote the growth of seedlings and enhance the resistance to adverse factors such as drought, low temperature and disease. Seed fertilizers include small amounts of nitrogen, phosphate, potassium and trace element fertilizers.

The amount of seed fertilizer should be controlled and the seed fertilizer should be isolated to avoid burning seedlings. Generally, 5-8kg of diammonium phosphate per mu is applied, and the effect is good.

I think corn is generally grown on a large scale in Shanxi, Henan, Hebei, Liaoning and Heilongjiang.

The planting scale in the northern region is relatively large, mainly concentrated in Henan, Hebei, Shanxi, Inner Mongolia, Heilongjiang and other places, the planting area is very large, and the quality is also very high.

Sweet corn can be divided into spring sowing and summer sowing in the north, but the seedling emergence cycle is longer due to the low temperature during spring sowing. Sweet corn seeds are small, high sugar content, often pecked by rodents and pheasants, resulting in the lack of seedlings and broken walls from time to time, replanting due to the time difference, uneven impact on the yield of seedlings during the seedling period, according to the normal management of ordinary seedlings, mainly to promote the seedlings to be robust, prevent pests and diseases, weeding, etc. (specific disinfection and germination seedling methods, please refer to my previous articles related to seedlings), and then transplant the field in due course.

<> it is recommended to buy planting. The annual rain is unstable, there are many varieties of stable yield, drought resistance, high yield, this is originally dependent on the sky to eat, high-yield moisture to be sufficient, sunshine is also sufficient, to high yield is not as good as high economy, now sticky corn is very good to sell different corn varieties in different regions of different yields, in the Huanghuaihai area suitable for planting varieties of Zhengdan 958 corn seeds, in Henan, Shandong, Hebei three main corn producing provinces of the planting area of more than 10 million mu; The variety Xianyu 335 set off a storm of single-grain sowing.

For example, if the soil is well conditioned, a large amount of organic fertilizer and chemical fertilizer are needed to adjust it, so that the soil can reach a good condition. Corn can grow in this area for benign development, and together with watering and pest management, it can achieve a good effect. I have planted Longping 206, the yield per mu is OK, about 1300 catties, we are loess soil, afraid of falling in autumn, this variety is still more suitable for us to plant there, the corn is ripe, its straw is still alive, many varieties are corn mature, the straw is dead.

It is observed that the requirements for the growth environment of high-yielding varieties will be stricter than that of stable varieties, and in the open-air field planting environment, the weather changes are not good, we all say that farming depends on the sky to eat, so when the external environment changes too much, many friends will choose to plant stable varieties. This area requires 10 active accumulated temperatures of more than 2100, and there are relatively few varieties suitable for this area, such as Demeiya No. 1, Heyu 183 approved by Inner Mongolia in 2016 and Tunyu 188 approved by Shanxi Province in 2013.

Jundan 18, Xianyu 508, Junyan 18, Weike 702, Nongda 84, Nonghe 518, Shengyu 18, Damin 3212, Cangyu 6s.

Tianta No. 3, Qingnong 105, Xianyu 335, Qingnong No. 8, Xixing Acacia Nuo No. 1 and so on are more suitable for planting in the north, and the survival rate is very high.

Jin Shuai. This variety of corn has a particularly wide adaptability, which is relatively drought-tolerant, cold-tolerant, and frost-tolerant, and is very suitable for planting in the north.

Most of the corn varieties can be grown in the northern regions. For example, Jingke 968, Xiangyu 998, Dongdan 1331 and so on.

If you want to grow corn in the north, try to choose Shengyu 18, Junyan 18, Xianyu 508, Ganyu 358, Jingdan 28, Liyu 37, Denghai 61, Yimu 969.

Nongda 108, Nongda 3138, Zhangyu 2, Pingyu 5, Chengyu 5, Shendan 10, Dongdan 60, Hudan 2000, these can be.

We all know that in fact, for most farmers now, they grow some crops at home, in fact, the income is also very considerable, and now agriculture is combined with mechanization in a way, so it is relatively easy, so some people will have such doubts, that is, I am planting corn all year round on the land to plant something else. In my personal opinion, I actually think that growing potatoes and peanuts is a very good choice, so let's take a closer look.

1 Potatoes can be planted

I believe that everyone has a certain understanding of the secret, we all know that corn in the process of planting, it is necessary to bring the interview without water, if the water is accumulated for many years, then it is likely to cause the seeds to rot, so if it has been planted in this year. The corn field can be used to grow potatoes in the next year, because the potato dumplings themselves are roughly the same as the corn planting, and the nutrients it needs are complementary.

2 Plant peanuts

In my personal life experience, in fact, many times I will see some farmers planting peanuts, in fact, the land where they planted peanuts was originally the land they used to grow corn, which is also a kind of experience accumulated by farmers, although I have not personally done these things, but after watching others plant, I actually have a certain understanding of some of your things. So I think if we planted corn last year, we can plant peanuts this year.

For many crops, in fact, if you want to plant these things, we should understand their nutrient needs in advance, and also look at what kind of problems need to be paid attention to in the planting process, so as not to have a variety of problems in the planting process, which will lead to reduced crop yields, so planting everything requires us to spend more time and energy to study. These are some of my thoughts on this issue.

You can plant some Ganoderma lucidum, shiitake mushrooms, or winter melon, it is very suitable to plant these plants, and at the same time, when planting, you must pay attention to seven points by sowing, three points by management, and you must take good care of the field.
