Corn cultivation is widely distributed in China, but it is mainly concentrated in the north and sout

China's corn planting area is about 300 million mu. It is distributed in about 24 provinces, municipalities and autonomous regions. Among them, Heilongjiang, Jilin, Liaoning, Hebei, Shandong, Shanxi, Henan, Shaanxi, Sichuan, Guizhou, Yunnan and Guangxi are the main provinces and regions.

The Huanghuaihai summer-sown corn area is located in the middle of China's corn belt, including the whole territory of Henan and Shandong, the central and southern parts of Hebei Province, the Guanzhong and southern Shaanxi regions of Shaanxi Province, the southern part of Shanxi Province, the northern part of Anhui and Jiangsu Province, and the annual corn planting area accounts for about 35% of the country.

<> maize is widely distributed in China, mainly in the northeast, north and southwest regions, forming a narrow corn planting belt from northeast to southwest, which concentrates 85% of China's total corn planting area and 90% of the yield. The history of corn cultivation in China is about 470 years. However, due to high yield, good quality and strong adaptability, the cultivation area has developed rapidly.

At present, China's sown area is about 300 million mu, second only to rice and wheat, and ranks third among grain crops.

In recent years, with the improvement of agricultural science and technology, the yield of corn has made a great leap in the past decade. The number of average corn yields in the country from a long-term point of view, is steadily increasing, but specific to each year, not every year is higher than the previous year, the natural conditions of China's corn producing areas are very different, according to the local frost period, soil texture, soil fertility, planting month, choose suitable varieties, forage corn and dentate hybrids yield high. Attention should also be paid to the breeding of improved breeds.

Although the growth of corn does not have very high requirements for the land, and can be grown on a variety of lands, it is still suitable for the geographical environment of deep soil layer, good structure, high fertility level, rich nutrition, loose aeration, and easy to store and drain, and the taste of corn also determines the quality of corn. Although I haven't eaten corn from all over the country. But according to the friends I have come into contact with, they have traveled from south to north

The cornmeal porridge they drank in the farmhouse, the cornmeal flatbread they ate. The taste is still more positive in the three northeastern provinces.

Because the climate in the north and southwest is distinct, which can ensure the necessary light and other conditions during the growth of corn, the south is humid and rainy, which can be planted but is not conducive to planting a large number of corn.

The temperature is more suitable, just the right cool temperature, just the right air, such a temperature is suitable for growth, and it is also very good.

Corn and rice are important food crops in the country, and they are widely cultivated in both the north and the south. It is understood that in 2017, the national rice planting area was 100 million mu, and the corn planting area was 35,590 thousand hectares, which is about 100 million mu. A small amount of sweet corn is grown in the south and eaten boiled, which is economical.

Some of the corn in the north is made of feed, and there is little for other purposes. The south is not suitable for planting corn in the north, and there is too much rain, and the yield of corn itself is not too high. The best of course is to plant corn in the north.

<>Of course, I'm talking mainly about the southeast of our country. Some locals also mostly work in factories, and their families don't have any land. At this time, there are some northerners who go to the south to plant land, including people I know in southern Jiangsu, Zhejiang and other places to plant land, I have seen in the mountains and fields, and there are still agricultural activities in the fields where most of the villages are less than 500 meters away, or less than 3 or 200 meters away from the road, because most of the people who farm now are old people, and their physical strength is not able to carry large things.

First of all, the first variety is "Jixiang 2188". This variety was accepted on-site in July 2016. According to the yield data, the yield of this variety has exceeded 700 kilograms per acre, far exceeding the national yield of 360 kilograms per acre at that time.

If spring maize is to be planted, farmers in the southern region can sow it from early March to early April. If you want to plant autumn corn, you can sow it from late June to mid-July.

Anhui Province has a long history of corn cultivation, especially in the northern part of Anhui, where the planting area is larger. "Zheng Dan 579" and "Denghai" series of corn varieties are suitable for planting in Anhui. The high-yielding sweet corn varieties suitable for cultivation in the south are:

Lu Tianyu No. 1, Lu Tianyu No. 2, Lu Tianyu No. 3, Nongmei No. 2, Tianyu No. 2, etc. The waxy corn varieties that can be planted in Guangxi are: Zhejiang University Nuoyu No. 3, Meiyu Jiatian Nuo No. 7, Zhongnuo No. 1, Huanuo No. 1, etc.

Waxy corn, also known as waxy corn. The kernels contain a coarse, waxy endosperm with shiny vitreous (transparent) kernels similar to hard corn and tint corn.

Now there are many types of corn, from the color distribution, that is, white corn and yellow rain in the southern region is more sunny, and the water and soil are also relatively moist, the corn suitable for planting in the southern region is yellow corn, but some places have also made a great contribution to sowing white corn.

Green-fed corn and so on, the climate and temperature of this corn are very suitable for the south, and the yield will be particularly 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.

Be sure to water more and apply more fertilizer, and at the same time, you should pay attention to the looseness of the soil, spray some pesticides, and also add some nutrient liquid to turn the soil, and understand the moisture of the soil, so that you can grow better corn.

Corn is generally double-cropped in a year, and the corn planted in spring is generally sown at the end of April and harvested in August; Corn planted in autumn is generally sown at the end of July and harvested in October.

Corn is grown in the north in the spring, and in the south in the spring and summer.

Tohoku also has warm periods throughout the year.

Spring-sown early-maturing varieties, 70-100 days, summer-sown, 70-85 days, medium-maturing varieties, 100-120 days, late-maturing varieties, 120-150 days.

If according to the early maturing varieties, the Northeast 1 3 time is in a warm and suitable time for corn growth, which is the reason why corn is suitable for planting in the Northeast. As long as the corn varieties with little climate change during the growth cycle are suitable for planting in the Northeast.

The ** of corn has been going on and on, and it can be said that the ** in the market is very good. Farmers definitely want to be able to increase their family's income in this way, so they grow a variety of corn. When choosing a corn variety, you must be very careful, for fear that if the variety is not selected well, the yield will eventually become very low.

If the corn grown by the farmer does not have a good yield, there will definitely be no way to get a high profit in the end. Some corns are not adapted to some places at all, so they grow very small. <>

When planting corn, you can choose to try Liangyu 99, because 5,000 corn seeds can appear in one acre of field. On average, each mu can produce 900 kilograms, and the highest can reach more than 1,000 kilograms. Most farmers grow this corn after the fall.

Because Liangyu 99 is a late-maturing variety of corn, it can be planted in a large area. In this way, it is actually hoped that it can have a value preservation effect, so that corn does not lose money. <>

Farmers are so struggling with varieties of corn because the right corn variety is half the battle. If you choose a bad corn variety, it won't last long before it dies. Corn is very demanding on the soil and must be very adaptable.

If there is no way to guarantee this, there is certainly no way to have a good yield. If farmers don't understand this, they can choose to ask those who have more experience what they should buy. <>

In general, field management is absolutely indispensable after planting corn, and it is necessary to fertilize and weed in time. If there is too much grass, it will continue to absorb the nutrients of the corn, making the corn very short. Fertilizing the corn according to its growth can make it bigger and bigger.

Different varieties of corn require different nutrients, and farmers should learn more about corn planting skills.

There are many types of corn, among which high-starch corn is the easiest to grow, and it will also bring a lot of economic benefits.

There are many different types of corn, and the easiest type of corn to grow is called Mexican corn.

Longgao L2 is a very high-yielding corn variety, and under the condition of suitable water and fertilizer conditions, it has set a high yield record of 32,000 catties per hectare. Longgao L2 maize variety has a wide range of adaptation areas and is suitable for Heilongjiang Province.

Cultivated in temperate zones of the first and second accumulation.
