Black soil is a precious soil resource, how can farmers protect and make good use of black soil?

This is not black soil dug in Wuchang City, Heilongjiang Province. This is a "facsimile soil" or fat burning soil on the ground in black soil. This "traction soil" or peat soil, although more nutritious, is not suitable for field crop production because it is too soft for mechanization or even for artificial cultivation.

This "draught soil" or peat soil is characterized by the absence of "roots" and falls as the water level rises.

If it's a rice field, talent will suddenly sink into the thigh. This "draught soil", or peat, is common in many parts of Heilongjiang, where I once saw a rice field developed on a raft. In September, after nearly a month of drainage, the paddy fields came back to life.

You can imagine how much resistance there is when it comes to preparing, planting, and harvesting this paddy field.

This is because this "traction soil", or peat, is too soft and does not have a strong load-bearing capacity. Traction soil, also known as peat, is a soil that is rich in nutrients, but not conducive to large-scale agricultural production. If it is classified, it should be classified in the "dark brown soil" category of "meadow dark brown soil".

Although the presence of this "draught soil" or peat soil is not conducive to agricultural production, it is very useful. For example, most of the nutrient soil for cultivating flowers is this ** expensive "grass root soil" or peat soil, and the use of this "grass root soil" or peat soil to produce seedling substrate or agricultural seedling substrate is also very popular, about hundreds to thousands of yuan per ton**, which is very profitable.

The content of soil organic matter was high, the types of decomposition products were high, and the content of effective humic acid or fulvic acid was high. In fact, the black soil stolen from Heilongjiang is not ordinary black soil, but a special kind of soil with many decaying plants. This soil is called peatland, and it is a special soil with a high organic matter content.

It must form in a particularly low-lying environment, and it must go through years of decay before a large amount of organic matter becomes part of the soil and mixes with it. So this soil takes a long time to form, and it is a depleting energy source.

In the black soil, we can grow tomatoes, cucumbers, lettuce, celery, apples and many other vegetable plants. Because planting these vegetables on the black soil can improve the yield of vegetables, and can also make vegetables grow better, and can also ensure the quality of vegetables, in ordinary life, people can not destroy the black soil at will, the relevant departments must issue some new policies

Farmers should not apply too much fertilizer to the soil when planting, and do not use some pesticides and disinfectants on the soil, so as to protect the soil and make better use of the black soil.

Every spring, find some agricultural technicians to test the soil and fertilize the land, what is missing, and the straw is directly returned to the field, which effectively improves the content of soil organic matter to provide mechanical guarantee and avoid excessive use of chemical fertilizers to cause soil compaction.

Legal analysis: The protection of black soil is the measures taken in response to the degradation of black soil, and the measures usually taken are mainly in the following aspects: 1. Ecological protection of farmland.

2. Soil and water conservation management of black soil in the gang-shaped undulating high plain. (1) According to the comprehensive management of black soil in the Xiaoliu Pai Xiang Ant Domain, the slope is greater than 3° and the exposed section of the parent yellow clay should be returned to grassland and the original ecology should be restored, and then shrub fruit forests (wild hawthorn, etc.) should be cultivated. The depression between the hills or the flat land that is easy to be eroded by water should be returned to farmland, and the swamp willow and Mongolian willow should be cultivated to restore the ecology of the willow maogang.

2) All cultivated land shall be forested and retained for windbreak and soil consolidation. (3) Change the traditional tillage mode and adopt the practice of no-turning land and straw returning. (4) Pay attention to biological protection.

When the ditch erosion is serious, the ditch should be closed for afforestation, and the valley should be built in the ditch to store water and soil. In areas with serious erosion, farmland can be returned to forests and grasslands. 3. Fertilize the soil.

In order to fertilize the soil and maintain a good aggregate structure, organic fertilizer should be increased, and straw returning should be actively advocated and promoted, especially straw returning to the field, and formula fertilization and balanced fertilization should be done. Establish a system of tillage, crop rotation and fertilization to maintain and improve the fertility of black soils. 4. Moisture protection tillage and irrigation and drainage matching.

Legal basis: "Land Management Law of the People's Republic of China" Article 2 The People's Republic of China implements the socialist public ownership of land, that is, the ownership of the whole people and the collective ownership of the working people. Owned by the whole people, that is, the ownership of all land owned by the state is exercised by *** on behalf of the state, no unit or individual may occupy, buy or sell or illegally transfer land in other forms, land use rights can be transferred in accordance with the law, the state for the needs of the public interest, can expropriate or expropriate the land in accordance with the law and give compensation, the state implements the system of paid use of state-owned land in accordance with the law, however, the state allocates the right to use state-owned land within the scope prescribed by law.

The rational protection and utilization of black soil is also for the purpose of implementing the scientific concept of development, and it is also a must for human beings. Based on the national conditions of our country, we should also be able to find that our country has always been overpopulated and underlanded, so we must protect the black soil, so as to ensure that the country's food is sufficient. Many people do not have a strong awareness of the protection of black soil resources, so it will cause land waste, and there are even some habits of destroying the ecology.

Some farmers may have a weak sense of law, so they will use these black soil in violation of laws and regulations, which requires the local ** departments and some leading cadres to introduce relevant policies to urge these people to protect the black soil and develop the black soil reasonably. Because our country is now constantly developing and transforming these old industrial bases in Northeast China, the consumption of these energy resources is also relatively large, and the land is gradually in short supply. <>

At this time, we should pay more attention to the protection of the black soil, because the black soil itself is relatively large, if you don't make good use of the stove, then the grain output will definitely decrease sharply, and our Liang Shi will be insufficient, and Liang Shi's ** will also **. Therefore, the relevant departments must introduce relevant policies to make everyone pay attention to the protection of black soil, and at the same time, we must also pay attention to the protection of the environment in our daily life, make reasonable use of black soil, and do not develop indiscriminately. <>

Or when building a house, try not to go to Senla to destroy these black soils, and you must have a very strict plan to control the total amount of land. At the same time, it is also necessary to carry out a rational layout, optimize the structure of land use, and adjust the structure of land use according to the specific conditions of the locality. We must work hard to improve the allocation and efficiency of the use and use of black soil, use black soil to the greatest extent, and reduce the pressure on the occupation of black soil.

For example, some illegal and idle black soil must also be managed and managed, and the role and advantages of black soil must be strengthened.

In order to let local farmers understand the importance of black soil, some relevant policies should be introduced in the local area.

It is necessary to formulate certain policies, and to strengthen supervision and control, so that measures can be taken to protect the black soil at the root.

Do a good job in planning the utilization of the black soil area of Peina. Strengthen the research on geology, land, agriculture, etc., comprehensively understand the black soil resources, control the direction of land utilization, do a good job in land use planning in the black soil area, and coordinate the protection and utilization of black soil resources.

First of all, the residents of the places where we have black soil should cherish and protect the black soil, and it is strictly forbidden to occupy cultivated land to do some other things.

The black soil in the northeast of our country is unique to the black soil, and it can be said that the quantity is still relatively limited, so it is still necessary to use and maintain the black soil, first of all, I think it is necessary to develop and use it reasonably. Do not waste, do not put it on hold.

While using the land, it is also necessary to leave him a part of the self-circulating sparrow judgment and purification ability. The use of land to protect the land is combined, and the most chaotic benefits are obtained with the least residual damage.

What are the problems faced by the quality of black soil? What are the forms of protection and utilization? What's the difficulty?

Black soil is in the cold climate conditions, the surface vegetation after a long period of erosion to form humus, with its high organic matter content, fertile soil, loose soil, the most suitable for farming is known as the world's "granary". The main crops in the black soil are rice, corn, soybeans, wheat, and potatoes. On the one hand, it is nurtured by water and soil, and on the other hand, it is people.

As my friends probably know, the world is not afraid of the earth, but of the eloquence of the Manchurians. They are the black soil that nurtures them.

In semi-humid and semi-arid areas, due to the combined influence and interference of natural and human factors, a desert-like landform is formed, which is called sandy land. Due to the large amount of sandy land, it is suitable for planting drought-tolerant plants with low water requirements, such as peanuts, soybeans, Chinese medicinal materials, etc. However, it should be noted that the effect of impounding water on sandy ground is limited.

Irrigation should be carried out in time during the dry season to avoid water shortage. Don't plant tall crops like corn. The black soil is suitable for growing crops such as sorghum, corn, wheat, rice, and soybeans.

The sandy land is suitable for planting peanuts, sweet potatoes, watermelons, pumpkins, aloe vera and other fruit trees, and the black soil is rich in a variety of nutrients, especially decaying plants, which can enhance the color, brightness and stress resistance of plants, and can promote plant seeds: full, good quality, good products, etc. Heilongjiang and Jilin are famous for their rice, and the high grain is the raw material for making high-quality wine.

Wheat and corn also need fertile soil, so they are also suitable for the production of black soil. Soybean is a nitrogen-fixing plant that grows on nutrient-rich soil and controls the rational use of water and fertilizer. It can also achieve the desired effect.

The sandy soil is the soil with high sand cover branch, relatively poor ridge cropping, and poor water-holding conditions, which is suitable for the production of early resistance and early resistance plants, and is very suitable for watermelon and sweet potato to become sandy land and sweet potato fruit.

Sandy soils have soft soils and good air permeability, which is conducive to the rapid growth of plant roots. Only the stool should pay attention to sufficient water and fertilizer**, and satisfactory results can also be achieved. Like peanuts, sweet potatoes, potatoes, they are stem plants that grow in sandy soil, and when there is plenty of water and fertilizer, they are stronger than root plants, big and fast, sweet and tasty, and of good quality.

Fruit trees such as apples and pears have a special taste due to their well-developed plant systems, abundant sunlight, heavy fertilizer and water, and high root absorption rate. So as to win the recognition of consumers.

Causes: Black soil is under cold climate conditions, after the death of surface vegetation after a long period of erosion to form humus after the evolution of the formation, with its high organic matter content, fertile soil, loose soil, the most suitable for farming, famous for the world, known as the "grain warehouse". It is the most suitable soil for crop growth, and it is also the most valuable non-renewable soil resource in the world.

China's black soil is mainly distributed in the Northeast Plain, located in the northeast of China, including Heilongjiang, Jilin, Liaoning, and the northeast of Inner Mongolia. Black soil gets its name because it is black, and the black soil has a high content of organic matter, so it appears black. The black soil area in Northeast China mainly includes the Songnen Plain, the Sanjiang Plain, the Daxinganling Piedmont Plain, the Liaohe Plain and other areas.

The black soil layer is the humus layer in the soil, and its thickness is an important indicator of soil fertility in the black soil.

The black soil is formed by the formation of humus after a long period of erosion after the death of surface vegetation under cold climate conditions, and is known as the "grain storehouse" because of its high organic matter content, fertile soil, loose soil, and the most suitable for farming.

In addition, it takes 400 years to form a 1 cm thick black soil layer, so the soil layer is extremely rich in humus and organic matter.

There are three famous black soils in the world: one in the Mississippi River basin in the Americas ——— the United States; a piece of Ukraine on the Dnieper River in Europe ———; One in Asia——— China's Songliao River Basin and Sanjiang Grassland. The largest of these is the Great Ukrainian Plain on the Dnieper River, with an area of about 1.9 million km2 of black soil.

The second is the Mississippi River Basin in North America, with an area of about 1.2 million km2 of black soil. Finally, it is mainly distributed in China's Songliao River Basin and Sanjiang Grassland, China's black soil area, with an area of about 1 million km2, known as "Beidacang" is an important commercial grain base in China.
