The black soil of the Northeast Plain is very fertile, what is the reason for the formation of black

1. Black soil in Northeast China.

What are the reasons for this?

Northeast. It has a high latitude and belongs to the temperate monsoon climate.

The climate is cold and humid, the soil material is heavy and there is a seasonal permafrost. Summer and autumn are rainy, and the soil often forms an upper layer of stagnant, meadow herbaceous plants.

It is luxuriant, with large amounts of organic debris entering the soil both above and below ground. In the long winter, microbial activity is inhibited, organic matter decomposes slowly, and is converted into a large amount of humus that accumulates in the upper part of the soil, forming a deep black humus layer. The salt base in the soil is leached, carbonate.

It is also removed from the earth, and the soil is neutral to slightly acidic. Seasonal water retention in the upper layer causes the reduction of iron and manganese in the soil, and oxidizes in the dry season, forming iron and manganese nodules, especially in the subsurface layer.

Therefore, the black soil in Northeast China is a special meadowization process that evolves after long-term erosion and humus formation after the death of surface vegetation under cold and humid climatic conditions.

2. What does the black soil in Northeast China refer to?

The total area of the black soil area in Northeast China is about 1.03 million square kilometers.

Among them, the typical black soil area covers an area of about 170,000 square kilometers. It is the country's main commercial grain base, producing about 22,525 billion kg of commercial grain every year. The black soil in Heilongjiang and Jilin provinces is the most fertile land in China.

With a total area of 10 million hectares, more than 7 million hectares of cultivated land have been reclaimed, and its grain output has accounted for more than 60 percent of the two provinces.

3. What are the advantages of the black soil in Northeast China?

In the natural state, the humus layer of black soil can be up to 1 meter thick, rich in nutrients, and high in fertility. After the reclamation of black soil, the humus content decreased, and the soil erosion was obvious due to the heavy clay of the parent material, which is a problem that needs to be paid attention to in the utilization of black soil. The black soil in Northeast China is one of the most fertile soils in China, and the black soil distribution area is an important grain base.

It is suitable for a wide range of species, especially for the growth of soybean, corn, millet and wheat.

It can be seen that the black soil is a very precious land resource, which can be said to be the "giant panda in cultivated land", but in recent years, due to the constraints of natural factors and the destruction of human activities, soil erosion in the black soil area of Northeast China has become increasingly serious, and the ecological environment has deteriorated day by day. Therefore, let us participate in the action of protecting the black soil and win the "tough battle" of the black soil!

The weather in the Northeast is cold, and plants such as deciduous leaves are slowly decomposed by microorganisms, so the soil appears black.

The reason for the fertility of the black soil in the Northeast Plain is that it is rich in organic matter, the position is temperate monsoon climate, rain and heat at the same time, which is conducive to the growth of vegetation, located in the Northeast Plain, the terrain is flat, which is conducive to the accumulation of organic matter, the latitude is high, the temperature is low, and the dead branches and leaves and other organic matter are not easy to be decomposed, so as to accumulate year by year and finally form a thick humus layer of black soil.

The black soil resources in Northeast China are important land resources in China, mainly distributed in the eastern part of the Songnen Plain, and the black soil reclamation period in China is not long, but the degradation is relatively serious. In the process of utilization of black soil cultivated land resources in Heilongjiang Province, there are serious problems such as serious soil erosion, reduction of fertility, deterioration of physical and chemical properties, and expansion of medium and low-yield fields, which directly lead to the reduction of the quantity and quality of black soil cultivated land, which seriously affects the development of black soil productivity and the realization of sustainable agriculture in Heilongjiang Province.

In the context of the economic policy and development of revitalizing the old industrial base in Northeast China, these problems should be paid enough attention and tried to solve them, otherwise, they will become an important obstacle to the sustainable economic development of Heilongjiang Province and even the whole country.

The Northeast is located at a higher latitude and has a colder climate. The black soil is under cold climate conditions, the surface vegetation after the death of a long time after the erosion of humus after the evolution of the formation, with its high organic matter content, fertile soil, loose soil, the most suitable for farming is famous all over the world, known as the "grain warehouse". The black soil in Northeast China is a soil with black humus topsoil layer developed in the parent material of alluvial-flood deposits, sandy aeolian deposits, etc., and this kind of soil has fine particles, good properties and high fertility, which is suitable for farming.

China's black soil is mainly distributed in the Northeast Plain, and its administrative area involves Liaoning, Jilin, Heilongjiang and parts of eastern Inner Mongolia.

China has a large population and a small per capita arable land, and in the event of a famine, the consequences will be unimaginable. It is precisely because we have a sense of "food shortage" that our country has been increasing grain production. At present, China has achieved the good result of "nine consecutive increases" in grain production, the grain self-sufficiency rate has been maintained at more than 95 percent for a long time, and the foundation for food security is solid.

At the same time, China is also constantly increasing its grain imports, giving grain a "double insurance".

The black soil area belongs to the cold temperate continental monsoon climate, with four distinct seasons, long, cold and dry winters, and the average annual temperature is around. Black soil is generally considered to be a soil formed under temperate steppe meadow conditions, and its natural vegetation is grassland meadow plants. At the time of formation, most of the parent material is loess clay, and the soil texture is heavy, the water permeability is poor, and there is a seasonal frozen layer.

In the warm and rainy summer, the plants grow luxuriantly, resulting in a very large annual accumulation of aboveground and underground organic matter. At the end of autumn, the frost period arrives very early, causing plants to die and be stored on the surface and underground, and as the temperature drops sharply, organic matter such as branches and leaves do not have time to decompose. The black soil particles are fine, uniform and consistent, the reason is: the particle size of the soil-forming parent material determines the soil characteristics, and the black soil is mainly distributed in the Northeast Plain, where the terrain is flat, the surface is more flowing water or wind sediments, and the soil-forming parent material particles dominated by flowing water or wind sediments are fine and uniform.

The climatic environment of the formation of black soil is because the area is relatively cold, and then the soil is frozen, and at the same time, the nutrients contained in the soil are also locked in it, so the black soil is more fertile.

Black soil generally survives in a relatively cold environment, and after a long period of erosion and evolution, a lot of humus remains in the land, which increases the organic matter content of black soil and makes the soil more fertile.

Black soil is a soil that slowly evolves after a particularly cold climate and long-term erosion of surface vegetation, and the organic matter content of black soil is particularly high.

Summary. Dear dear, it's a pleasure to answer your <>

The reason for the fertility of the black soil in the Northeast Plain is rich in organic matter, the position is temperate monsoon climate, rain and heat at the same time, which is conducive to the growth of vegetation, located in the Northeast Plain, the terrain is flat, which is conducive to the accumulation of organic matter, the latitude is higher, the temperature is low, the litter and other organic matter are not easy to be decomposed, so as to accumulate year by year and finally form a thick humus layer of black soil.

The reason for the fertile black soil of the Northeast Plain.

The reason why the soil of tropical rainforest is poor and the soil of the northeast plain of China is fertile.

Good. Dear dear, it's a pleasure to answer your <>

The reason for the fertile black soil of the Northeast Plain is rich in organic matter, the position of temperate monsoon climate, rain and heat at the same time, conducive to the growth of vegetation, located in the Northeast Plain Plain, the terrain is flat, conducive to the accumulation of organic matter, the latitude is higher, the temperature is low, the dead branches and leaves and other organic matter do not seep into the clear field and are easy to be decomposed, so as to accumulate year by year and finally form the thick saprophyllum layer of the black soil.

Kiss, the tropical rainforest soil is poor, and the original soil in the northeast of China is fertile: the soil structure in the general tropical rainforest system is littered with litter on the soil, but there is not much black humus that completely decomposes and forms a poor oak. Underneath it is the surface layer of the soil, which is dominated by leaching.

Not only will soluble minerals be lost, but even soil particles will be easily decomposed or washed away, leaving only iron or aluminum oxides. This is the main reason why the soils in tropical rainforest systems are poor.

1. The characteristics of sandy land: the sand content is relatively large, and the soil quality is relatively small. This determines the nature of the sandy soil leakage and water leakage, although the moisture retention is not very good, but the sandy soil is easy to drain and breathe, and naturally regulates the soil temperature, so the nature of the sandy soil is still relatively unique.

Although sandy land is relatively barren due to the relatively small amount of soil, it is not easy to grow crops. However, this kind of sandy soil also has its advantages, sandy soil contains a large number of material elements that are conducive to the growth of crops, especially calcium, nitrogen, phosphorus and potassium are very rich.

Second, the characteristics of black soil: this soil contains a large amount of organic matter, after the baptism of four seasons of wind, rain, snow and frost, a large number of animal and plant matter in the soil, long-term fermentation makes the soil full of a large number of organic fertilizers, is suitable for the growth of crops must be an ingredient. Also, the moisture in the soil is relatively moist.

However, black soil is rich in metallic substances, which interact with each other in acidic and alkaline soils, which has a negative impact on individual crops.

Third, look at the adaptability of peanuts. Peanuts are more adapted to soils with low acidity and are particularly sensitive to soils containing salinity.

Based on the above analysis, it was found that peanuts were very suitable for the growth of sandy soil. Practice has proved that peanuts grown in sandy soil are not only full of grains, but also have high oil content.

Peanuts are not too strict on soil texture, except for too clay soil, general texture soil can be planted with peanuts. The most suitable soil for planting peanuts is the sandy loam soil with medium to high fertility, solid on the top and on the bottom, loose and breathable, peanuts are suitable for planting in sandy soil, generally speaking, peanuts like to grow in a neutral and acidic environment, of course, it is not that all neutral and acidic environments are suitable for the growth of peanuts, for peanuts, they need to live in those sandy places, because their growth needs a lot of oxygen, which is conducive to the formation of peanut oil, so that peanut grains are full, good quality and high yield. However, sandy soil is easy to cause water and fertilizer loss, so it is necessary to pay attention to a small amount of fertilizer and watering many times.

The so-called soft soil is not suitable for their growth, because the oxygen in those lands is not particularly abundant, so it is not a particularly good environment for peanuts. Black soil generally evolves after the death of surface vegetation and the formation of humus after a long period of erosion under cold climate conditions. It is fertile, with deep humus, high organic matter content, good aggregate structure, and is the most fertile soil.

So it can be planted!

The black soil has high organic matter content, large yield, comprehensive nutritional structure, and rich fertility, and the wide distribution of black soil in Northeast China can increase the yield and add impetus to the economic development of Northeast China.

Northeast China has unique black soil, fertile land, abundant sunlight, large temperature difference conducive to the accumulation of nutrients, and few pests and diseases.
