What kinds of soils are there in China at present, and where are they distributed?

China's soil can be divided into red soil, brown soil, fluvial soil, desert soil, wet soil, alpine soil, saline soil, etc., mainly distributed in the northwest and northeast of China, in addition, South China is also distributed.

There are about 15 main soil types, namely: brick red soil, red red soil, red yellow soil, yellow-brown soil, brown soil, dark brown soil, cold brown soil, brown soil, chernozem, chestnut soil, brown soil, black soil, desert soil, alpine meadow and alpine desert soil. It is mainly found in the black soil of the Northeast.

The red clay of Guangxi, the loess of Shanxi, Shaanxi.

The vast restoration of our country is also the main soil of 15 species. It is mainly found in the black soil of the Northeast. The red clay of Guangxi, the loess of Shanxi, Shaanxi.

As of June 2020, Chaisun Korla City has 9 townships, 3 towns, 5 state-owned agriculture, animal husbandry and horticultural farms, and 14 sub-district offices: Tuanjie Street, Sayibagh Street, Tianshan Street, Xincheng Street, and Jianshe Street.

Chaoyang Street, Lixiang Street, Tashidian Town, Shanghu Town, Xinier Town, Tiekeqi Township, Charbagh Township, Yingxia Township, Langan Township, Heshilik Township, Hala Yugong Township, Awati Township, Tobuliqi Township, Puhui Township.

In Korla City, there are 9 agricultural and animal husbandry horticultural farms, and 2 regimental farms under the Second Division of the Corps: Kurchu Horticultural Farm, Baotouhu Farm, Puhui Farm, Bazhou Awati Farm, and Bazhou Shayidong Horticultural Farm.

Bazhou Dairy Farm, Pratt & Whitney Ranch, Economic Ranch, Improved Seed Farm, 29th Regiment of the Corps, 30th Regiment of the Corps. As well as the Second Division of the Xinjiang Production and Construction Corps, PetroChina Tali Burying Hall Wood Oilfield Branch and other ** and autonomous region units.

China's soil can be divided into three categories according to its texture: sandy soil, clay soil, and loam.

1. The sandy soil has a loose texture, many coarse grains, and the soil nutrient content is small, and it does not retain water and fertilizer.

Second, the organic matter content of clay soil is high, the fertilizer retention performance is strong, and the nutrients are not easy to be lost, but the permeability is poor, the fertilizer effect is released slowly after fertilization, and the crop is difficult to take root.

3. Loam soil is a kind of soil with good agronomic characteristics, and its permeability, water and fertilizer retention capacity and potential nutrient content are between sandy soil and clay.

The types of soil occurrence in China can be summarized into red soil, brown soil, brown soil, black soil, chestnut lime soil, desert soil, fluvial soil (including sand ginger black soil), irrigated silt soil, paddy soil, wet soil (meadow, swamp soil), saline-alkali soil, lithologic soil and alpine soil.

1. Black soil. The east and west sides of the mountains in the central and southern sections of the Daxing'an Mountains, the central part of the Songnen Plain in the northeast and the watershed areas of the Songhua River and the Liao River. Temperate semi-humid continental climate. The average annual temperature is -3 3 , and the annual precipitation is 350 500 mm.

The vegetation is temperate grassland and meadow grassland with the highest grass yield. The humus content is the most abundant, the thickness of the humus layer is large, the soil color is mainly black, showing a neutral to slightly alkaline reaction, calcium, magnesium, potassium, sodium and other inorganic nutrients are also more, and the soil fertility is high.

2. Brick red soil.

Hainan Island, Leizhou Peninsula, Xishuangbanna and the southern part of Taiwan Island are roughly located south of 22°N. Tropical monsoon climate. The average annual temperature is 23 26 and the average annual precipitation is 1600 2000 mm.

The vegetation is tropical monsoon forest. The weathering leaching effect is strong, the soluble inorganic nutrients are lost in large quantities, and the iron and aluminum remain in the soil, and the color is red. The soil layer is deep, the texture is sticky, the fertility is poor, and it is acidic to strongly acidic.

3. Loess soil.

It is also known as loess soil, which is widely distributed in the hilly areas of the middle reaches of the Yellow River. The color of the soil is very similar to that of the parent layer, the texture is uniform, loose and porous, the tillage is good, the organic matter content is low, and the mineral nutrients are abundant.

Black soil in the Northeast. The Crimson Wolf of the South.

Soil can be divided into three types: sandy soil, clayey soil, and loam.

The main types of soil occurrence in China can be summarized into red soil, brown soil, brown soil, black soil, chestnut lime soil, desert soil, fluvial soil (including sand ginger black soil), irrigation and silt soil, paddy soil, wet soil (meadow, swamp soil), saline-alkali soil, lithologic soil and alpine soil.

1. The properties of sandy soil: high sand content, rough particles, fast water seepage, poor water retention performance, and good aeration performance.

2. The properties of clayey soil: low sand content, fine particles, slow water seepage, good water retention performance, and poor aeration performance.

3. The nature of loam: general sand content, general particles, general water seepage speed, general water retention performance, and general ventilation performance.

Differentiation and assemblage of soil species on the Earth's land surface. It is closely related to the comprehensive change of physical geographical conditions.

Brick red soil, red red soil, red soil, yellow soil, yellow-brown soil, dark brown soil, brown soil.

After dozens of hundreds of years of accumulation, the soil is rich in humus required by plants, and the black soil is a unique treasure given to human beings by nature, with an area of about 1.9 million km2 and an area of about 1 million km2! Because the black soil has a lot of organic matter and the soil is moderately acidic and alkaline, with an area of about 1.2 million km2, it is known as the "North Warehouse" of China's important commercial grain base, because the predecessor of the black soil is mostly swamps, and the content of various elements (such as nitrogen, phosphorus, potassium, etc.) that are beneficial to plant growth is moderate &-

Black soil mainly exists in the Northeast Plain in China; The second is distributed in the Mississippi River Basin in North America. There are only three major black soil areas in the world, which are very suitable for plant growth, and the swamps contain a large number of dead remains of plants and animals.

Conversion into organic minerals; The third is the Northeast Black Soil Area distributed in the Songliao River Basin of China, which is a kind of soil with good traits &-& The most fertile soil in China is the "Northeast Black Soil"! The first is distributed in the Great Plains of Ukraine.

Hehe, high fertility.

- The most fertile soil in our country is the "Northeast Black Soil", because the black soil has a lot of organic matter, the soil is moderately acidic and alkaline, and the content of various elements that are beneficial to plant growth (such as nitrogen, phosphorus, potassium, etc.) is moderate

Black soil mainly exists in the Northeast Plain in China, because most of the predecessors of the black soil were swamps, and a large number of animals and plants in the swamps were left behind after death.

Converted into organic matter minerals, after dozens of hundreds of years of accumulation in the soil rich in humus required by plants, the black soil is a unique treasure given by nature to human beings, is a kind of soil with good characteristics, high fertility, very suitable for plant growth. There are only three black soil areas in the world: one is distributed in the Great Plain of Ukraine, with an area of about 1.9 million km2; the second is distributed in the Mississippi River Basin in North America, with an area of about 1.2 million km2; The third is distributed in the northeast black soil area of the Songliao River Basin in China, with an area of about 1 million km2, which is known as the "North Warehouse" and is an important commercial grain base in China.

Hehe!!!
