Where are China s three major granaries? What are China s four major granaries

China's four major granaries are defined as China's four major plains, which mainly produce rice:

1. Northeast Plain.

It is located in the northeast of China, in the Greater and Lesser Khing'an Mountains.

With an area of 350,000 square kilometers, it is the largest plain in China. Most of the elevations are below 200 meters, and the ground is vast and open, including the Sanjiang Plain and the Songliao Plain.

Songliao watershed, Liaohe Plain, many swamps along the river. It mainly includes Heilongjiang, Jilin and Liaoning provinces.

2. North China Plain.

From Taihang Mountain in the west.

It reaches the seashore in the east, Yanshan in the north, and the Huai River in the south.

With an area of 300,000 square kilometers, it is composed of the Yellow River, the Huai River and the Hai River.

and other sediments carried by rivers are deposited, also known as the Huang-Huai-Hai Plain.

The average altitude is less than 100 meters, the terrain is low and flat, the soil layer is deep, and the soil is fertile. It mainly includes Hebei Province, Henan Province, Beijing City, Tianjin Municipality and Shandong (including northern Jiangsu and northern Anhui).

3. Plain in the middle and lower reaches of the Yangtze River.

From Wushan. To the east to the seashore, it is alluvial by the Yangtze River and its tributaries. It covers an area of about 160,000 square kilometers.

The terrain of the plain is lower than the North China Plain, the average altitude is less than 50 meters, and the altitude in some places is less than 5 meters. It mainly includes Hubei, Anhui, Jiangsu, Shanghai, and northern Zhejiang.

4. Pearl River Delta Plain.

Located in the south-central part of Guangdong Province, with an area of about 11,000 square kilometers and an average altitude of about 50 meters, the river network here is vertical and horizontal, and the lonely hills are scattered.

National Food Security Efforts:

1. Strengthen reform and innovation, continue to deepen the reform of the grain procurement and storage system, further stimulate the vitality of the market, adhere to the principle of paying equal attention to market-oriented reform and protecting the interests of farmers, and improve rice.

and the minimum purchase price policy of wheat, reasonably determine the best level, and guide the establishment of a market operation mechanism for high-quality grain and high prices.

2. Further strengthen reserve management, continuously improve the efficiency and effectiveness of reserve operation, and ensure that it can be obtained, transferred quickly and used when needed.

3. Strengthen bottom-line thinking.

We should make every effort to do a good job in grain procurement and ensure that there will be no "difficulty in selling grain." We should do a good job in policy-based acquisitions and give full play to the role of support. Do a good job in market-oriented acquisitions and stimulate market vitality.

4. Further strengthen precise regulation and control, strengthen the construction of the grain market system, continuously improve the efficiency of grain supply, continue to hold the China Grain Trading Conference and regional fairs, take the national grain trading platform as the leader and the regional grain trading platform as the backbone, develop bulk grain spot trading, and smooth the circulation of grain.

5. Further strengthen risk prevention and control.

Improve the grain market monitoring and early warning system, continuously enhance the forward-looking, predictable, and pertinent nature of work, and continuously improve service decision-making and service industries.

The level of competence to serve the community.

1. Jiangsu: the land of fish and rice, the granary of the world.

This area mainly refers to the Taihu Plain and the Northern Jiangsu Plain, where the natural conditions are superior and the crops grow in a long season; At the same time, it has a long history of farming, abundant labor, a tradition of intensive farming, a certain foundation for farmland infrastructure, and good production conditions such as water conservancy and fertilizer, so it is the most important commercial grain base in China, known as the "land of fish and rice" in China.

2. Songnen Plain.

Black soil is a precious gift from God to the Northeast. There are only the northeast of our country, Ukraine, in the world.

Great Plains and the Mississippi River in the United States.

The basin has a large area of black soil. In the cold temperate zone with four distinct seasons, due to the lush vegetation and cold winter, a large number of dead branches and leaves are difficult to decay and decompose, and a thick humus has been formed after thousands of years, making the black soil the land with the highest fertility and the most suitable for farming.

3. Jianghan Plain.

The two lakes are ripe, and the world is full.

The mighty Yangtze River is in the middle reaches and her largest tributary, the Han River.

Confluence, containing 10,000 square kilometers.

of the Jianghan Plain. Countless small lakes are dotted around, the harbors are criss-crossed, the rivers and lakes are interconnected, and the ditches are as dense as spider webs. The rise of the Jianghan Plain in China is closely related to the development of agricultural technology.

A large number of wetland systems "river-lake-swamp, swamp-type paddy field-latent paddy field" support this main grain producing area. The output of the Jianghan Plain in 2013 reached about 10,000 tons, between the rivers, lakes and ports, the fertile fields are beautiful, and the fields are connected, all of which are pastorals, fish ponds and lotus ponds.

Classification of grain silos.

1) Classification according to the way the grain is stacked in the warehouse.

Bulk silos, packing silos.

2) Classification according to the shape of the warehouse.

Room-type silos, silos, building silos.

3) Classification according to the construction conditions and equipment configuration of the warehouse.

Simple silos, general granaries, mechanized granaries, prefabricated granaries.

4) Classification according to grain **.

Above-ground warehouse, underground warehouse, semi-underground warehouse.

1. Northeast Plain.

The Northeast Plain is one of the only three black soil regions in the world, and the grain output of the four northeastern provinces accounts for one-third of China's total output, which is an important production base of grain, soybean and animal husbandry in China, as well as an important base of coal, steel, machinery, energy and chemical industry in China.

2. North China Plain.

The North China Plain has a deep soil layer and fertile soil. Major food crops.

There are wheat, rice, corn, sorghum, millet and sweet potato, etc., cash crops.

The main ones are cotton, peanuts, rape, sesame, soybeans and tobacco. The North China Plain is an important production base of grain, cotton and oil in China.

3. Plain in the middle and lower reaches of the Yangtze River.

The middle and lower reaches of the Yangtze River are important production bases for grain, oil and cotton in China, and are also the most water-rich regions in China. The natural water system of the Yangtze River and the criss-crossing artificial canals make the area the densest river network in China. At the same time, the area is a Chinese freshwater lake.

The most concentrated area of group distribution, the famous freshwater lake is Poyang Lake.

Dongting Lake, etc. 4. Pearl River Delta Plain.

Estuarine area along the southeast coast of China.

All of them are formed by delta plains, of which the Pearl River Delta is the largest, which is formed by the confluence of three major rivers in the east, west and north, with an area of 10,000 square kilometers.

Above, it has become one of China's commercial grain bases. It is small in size, but it is highly productive, and can support nearly 1,000 people per square kilometer.

China's four major granaries, the Northeast Plain, the North China Plain, the middle and lower reaches of the Yangtze River Plain, and the Pearl River Delta Plain, are introduced as follows.

1. North China Plain.

The west side starts from the Taihang Mountain, the east reaches the seashore, the north can reach the Yan Mountain, and the south can reach the Huai River. With an area of 300,000 square kilometers, the North China Plain is formed by the accumulation of sediment carried by rivers such as the Yellow River, the Huai River and the Hai River, and is also known as the Huang-Huai-Hai Plain. The average altitude is below 100 meters, the terrain is relatively low and flat, the soil layer is very deep, and the soil is fertile.

It mainly includes Beijing, Tianjin, Hebei Province, Henan Province and Shandong (including northern Anhui and northern Jiangsu).

2. Northeast Plain.

The Northeast Plain is located in the northeast of China, between the Great Khing'an Mountains, the Little Khing'an Mountains and the Changbai Mountains, covering an area of 350,000 square kilometers, making it the largest plain in China at present. Most of the elevations are below 200 meters, and the ground is vast and open, including the Liaohe Plain, the Songliao Plain, the Songliao Watershed, and the Sanjiang Plain, and there are many swamps along the river. It mainly includes Liaoning, Jilin and Heilongjiang provinces.

3. Pearl River Delta Plain.

The Pearl River Delta Plain is located in the south-central part of Guangdong Province, covering an area of about 11,000 square kilometers, with an average altitude of about 50 meters.

4. Plain in the middle and lower reaches of the Yangtze River.

From Wushan to the east to the seashore, by the Yangtze River and the tributaries of the Yangtze River alluvial, the area is about 160,000 square kilometers, the terrain of the plain is lower than the North China Plain, the average altitude is below 50 meters, the altitude of some places is less than 5 meters, the river network is vertical and horizontal, there are many lakes, there is the name of the water town Zeguo. It mainly includes Jiangsu, Anhui, Hubei, northern Zhejiang, and Shanghai.

China's four major granaries: the Northeast Plain, the North China Plain, the Middle and Lower Yangtze River Plain, and the Pearl River Delta Plain.

1. Northeast Plain: It mainly includes Heilongjiang, Jilin and Liaoning provinces, and most of the rice and flour we buy every day come from these three places.

2. North China Plain: mainly including Hebei Province, Henan Province, Beijing City, Tianjin City, Shandong, northern Jiangsu, northern Anhui and other places.

3. The middle and lower reaches of the Yangtze River Plain: mainly including Hubei, Anhui, Jiangsu, Shanghai, and northern Zhejiang.

4. Pearl River Delta Plain: Located in the south-central part of Guangdong Province, it covers an area of about 11,000 square kilometers and has an average altitude of about 50 meters.

Advantages of the Northeast Plains:

The Northeast Plain is one of the only three major black soil regions in the world, and the grain output of the four northeastern provinces (regions) accounts for one-third of China's total output, and it is an important production base of grain, soybean and animal husbandry in China, as well as an important base of coal, steel, machinery, energy and chemical industry in China.

The woodland of the Northeast Plain is distributed in mountains and hills, and the cultivated land is distributed in plains and terraces, hills and mountains. Meadows are found in hills, plains, mountains, and mesas. Sandy land, i.e., Horqin Sandy Land, saline-alkali wasteland is distributed in the middle of the Songnen Plain, and wetlands are distributed in the Sanjiang Plain and along the banks of the river and its alluvial water-consuming bays.

Meaning:

The earliest age of the granary on the ground is the "pole bar" granary unearthed from the ruins of Hemudu, Zhejiang, and the silo also contains rice, which has been 7,000 years ago according to research, and is the earliest grain storage facility in the south that has been found so far. The larger-scale and earlier above-ground granary is the "Dafangpan" granary excavated in Dafangpancheng, Gansu Province. Dafangpan City, also known as Hecang City, is 60 kilometers away from Dunhuang City and about 20 kilometers away from Yumen Pass.

This warehouse was built in the Han Dynasty and was a military depot for the western frontier until the Wei and Jin dynasties. “

The world's four major breadbaskets: China, the United States, India, Brazil.

China, the United States, India, and Bayou are the world's four major grain production bases; In recent years, China and the United States have produced about 500 million tons of grain, and India and Brazil have produced 100 million tons and 100 million tons of grain respectively.

China is the world's largest grain producer, and it is a miracle in the history of the world that China feeds about a quarter of the world's people with the largest population, the least arable land per capita, and the largest grain production. The United States has highly developed agriculture and a high degree of mechanization, and is the second largest food producer in the world; India is a populous country, and the food it produces is largely for domestic consumption; Brazil is the world's second-largest exporter of soybeans and third-largest producer of corn, ranking among the top five in the world in corn exports.
