The distribution of wheat, the main distribution areas of winter wheat

1. The spring wheat area is mainly distributed in the north of the Great Wall, the west of Minshan and Daxue Mountain. Due to the short frost-free period, often less than 200 days, most of the cultivation system is once a year. Most of these areas are in the alpine or dry and cold zone, and the winter wheat cannot be safely overwintered, so spring wheat is planted;

2. The northern winter wheat area is mainly in the south of the Great Wall, east of Liupan Mountain, and north of Qinling and Huaihe rivers. This is the largest concentrated wheat producing and consuming area in the country, and the sown area and output of wheat account for about two-thirds of the country. Generally, the two-cropping system or two-year-to-three cropping is implemented, and it is a transitional zone with a mixture of winter and spring wheat on both sides of the northern Great Wall.

Since winter wheat is an overwintering crop, the planting of winter wheat has less contradictions with other food crops, which can reduce the area of idle land in slow winter, expand the area of summer planting, and increase the total grain output. As a result, the area sown to winter wheat has been expanding since 1949;

3. The southern winter wheat area is located south of the Huai River in the Qinling Mountains and east of Zheduo Mountain. The sown area and total output account for about 30 percent of the country. Because most of the people in this region rely on rice as their main ration, the commodity rate of wheat is relatively high, and it is an important production area of commercial wheat in China.

1.Huanghuaihai area.

The Huang-Huai-Hai region is one of the main winter wheat growing areas in China, including Shandong, Anhui, Henan, Jiangsu, Shaanxi and other provinces. The climatic conditions here are suitable for the growth of winter wheat, the land is fertile, and the irrigation conditions are good, which is an important base for the harvest of winter wheat.

2.North China.

North China, including Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia and other provinces, is one of the main winter wheat planting areas in China. The climate here is cold and dry, and the land is fertile, making it an ideal area for growing winter wheat. Winter wheat production in North China is among the highest in the country.

3.Yangtze River Basin.

The Yangtze River Basin is one of the economically developed regions in China and an important area for winter wheat planting. Including Jiangsu, Zhejiang, Anhui Mozhi, Hunan and other provinces. The climate here is mild and humid, the land is fertile, and the quality of winter wheat is excellent"Jiangnan Haomai Township"。

4.Southwest.

Buhui area in southwest China, including Yunnan, Guizhou, Sichuan and other provinces, is a secondary planting area for winter wheat blindness in China. The climatic conditions here are slightly worse, but there is still a certain area of winter wheat, which is of good quality because it is often grown at high altitudes.

5.Liaoning region.

The Liaoning region is one of the important agricultural bases in Northeast China and an important winter wheat growing area. The climate is cold, the land is fertile, and there are excellent conditions for winter wheat cultivation. In recent years, with the progress of science and technology and the application of new fertilizers, the yield of winter wheat in Liaoning has increased significantly.

6.Xinjiang region.

Xinjiang is one of China's important grain production bases and one of the important areas for winter wheat planting. The climate is arid and rainless, but there are abundant groundwater resources, and winter wheat production has increased significantly through irrigation.

7.Other regions.

In addition to the main winter wheat growing areas mentioned above, there are also some areas where winter wheat is grown, such as Northwest China, Jiangxi, Guangxi, Hubei and other provinces. These regions vary in climatic conditions and the fertility of the land, but all have a certain yield of winter wheat.

8.Brief summary.

In general, winter wheat in China is mainly distributed in various provinces such as the Huang-Huai-Hai region, North China, the Yangtze River Basin, Southwest China, Liaoning and Xinjiang regions. Although there are differences in climatic conditions and land fertility in these areas, farmers have mastered certain planting techniques through continuous practice and exploration, and have made certain achievements in improving the yield and quality of winter wheat.

Winter wheat is generally bounded by the Great Wall in China, spring wheat is generally used in northern China, winter wheat is used in the south, and winter wheat is the main wheat in China. Winter wheat is grown in warmer areas, usually sown from mid-to-late September to early October, and matures from late May to mid-to-late June of the following year. For example, in North China and south of it is winter wheat.

In China, it is generally bounded by the Great Wall, with the main brigade of Peking University as spring wheat, and the south as winter wheat. Winter wheat is the main source in China.

The northern winter wheat area is mainly distributed in the north of the Qinling Mountains and the Huai River, and the south of the Great Wall, where the winter wheat output accounts for about 56% of the total wheat output in the country. Among them, they are mainly distributed in Henan, Hebei, Shandong, Shaanxi and Shanxi provinces and regions.

The southern winter wheat area is mainly distributed in the south of the Huai River in the Qinling Mountains. This is the main rice producing area in China, and planting winter wheat is conducive to improving the multiple cropping index and increasing grain production. It is characterized by a high rate of commercial hole lifting stools. The main producing areas are concentrated in Jiangsu, Sichuan, Anhui and Hubei provinces.

Spring wheat area, mainly distributed in the north of the Great Wall. The temperature in this area is generally low, the production season is short, so it is mainly one crop a year, and the main producing provinces and regions are Heilongjiang, Xinjiang, Gansu and Inner Mongolia.

Wheat is suitable for growing in a long light time, fertile soil environment, when breeding wheat, it is necessary to plough the soil first, and then apply organic fertilizer and compound fertilizer to it, improve the nutrients in the soil, and to mix wheat seeds with insecticides before sowing, which is conducive to the healthy growth of plants.

1. Suitable environment

Wheat is a long-day plant, it is suitable for growing in the environment of sufficient sunlight, deep soil layer and fertile soil, when breeding wheat, it is necessary to plough 30 cm of land first, which is conducive to the growth of roots of plants, and then apply well-rotted organic fertilizer and nitrogen, phosphorus and potassium compound fertilizer to the soil to provide wheat with the nutrients needed for growth.

2. Seed dressing method

When planting wheat, it is necessary to select seeds with full grains and no pests, and then mix the seeds with a mixed insecticide, and then place them in the sun to dry for 1-2 days, and turn the wheat seeds every 2-3 hours to make them evenly exposed to light, reducing the probability of wheat infection.

3. Planting method

When sowing wheat, it is necessary to sow its seeds to the surface of the soil, and to water the wheat once, so that it can quickly produce pure reed seedlings, and during the rough growth of the wheat hall, it is necessary to apply urea and superphosphate to it, so that the growth rate of the plant is accelerated, and the wheat produces tillers.

4. Maintenance management

When maintaining wheat, it is necessary to spray jointing fertilizer to it during the heading period of the plant to avoid wheat lodging, and in May every year, it is necessary to spray potassium dihydrogen phosphate 2-3 times to reduce the harm of dry and hot wind, which is conducive to improving the yield of wheat, and to pull out the infected wheat seedlings to avoid its infection.

The five stages of wheat growth are as follows: sowing and seedling emergence stage, rejuvenation stage, jointing and pregnancy and coarse fertility stage, heading and flowering to grain filling stage and maturity stage.

1. Seedling stage. When sowing wheat seedlings, it is necessary to pay attention to the sowing depth, sowing too shallow, which will lead to lodging of wheat, and sowing too deep will lead to slow emergence of wheat, even if the seedlings emerge, there will be emaciation, yellowing and other symptoms. When the wheat seedlings need to be checked in time to replenish the seedlings, if the land is dry, it is necessary to use irrigation or drip irrigation for watering, not flood irrigation.

2. Rejuvenation. When the wheat enters the rejuvenation stage, it is necessary to reasonably control the prosperity according to the growth of the wheat seedlings, water the rejuvenation water, apply the rejuvenation fertilizer, and remove weeds in time.

3. Jointing gestation period. In the jointing breeding period, it is necessary to pay attention to the rock and start drought prevention, stain prevention and lodging prevention, because the jointing breeding period is the period when the wheat consumes the most water in its life, but there should be no water accumulation in the field, so it is necessary to do a good job of ditching and draining stains.

4. Heading and flowering to grain filling stage. From heading and flowering to the grain filling stage, in addition to watering well, it is also necessary to do a good job in the prevention and control of pests and diseases.

5. Maturity period. The endosperm is waxy and the kernels begin to harden, which is the ripening stage. This is the most suitable time for harvesting, and then the kernels quickly harden and are ripe. When the wheat reaches maturity, it needs to be harvested at the right time.

Worldwide, wheat is suitable for growing in temperate zones, continental climate zones and temperate monsoon climate zones.
