Slash and burn refers to what era in ancient China

The era of agriculture and animal husbandrySlash-and-burn farming is a way of cultivating land in ancient times.

Burn grass and trees to reclaim the land and make fertilizer.

Use knives and other iron tools to turn the ground and grow crops.

Slash-and-burn farming is a remnant of the Neolithic agricultural practice. Also known as migration agriculture, it is a primitive farming system. First with a stone axe, and later with an iron axe, the dead roots and stems of trees on the ground were cut down, and the plants and trees were dried and burned with fire.

The burned land becomes soft, does not turn the ground, uses the surface grass ash as fertilizer, no longer fertilizes after sowing, and generally plants one year after changing the land.

The remaining agricultural management methods of the Neolithic Age belong to the primitive farming system. First with a stone axe, and later with an iron axe, the dead roots and stems of trees on the ground were cut down, and the plants and trees were dried and burned with fire. The burned land becomes soft, does not turn the ground, uses the surface grass ash as fertilizer, no longer fertilizes after sowing, and generally plants one year after changing the land.

Due to the extensive operation, the yield per mu is only about 50 kilograms, which is commonly known as "planting a slope and harvesting a radio". As early as 5000 to 3000 BC, the Yangshao cultural area in the middle reaches of the Yellow River adopted the method of slash-and-burn cultivation and land rotation to grow chestnut and millet, and Yunnan also used this method to grow rice as early as 1260 to 1100 BC in the late Neolithic period of the Shang Dynasty. During the Warring States Period, the indigenous people of Yunnan widely adopted the slash-and-burn farming method.

After the l century B.C., slash-and-burn farming in central and western Yunnan gradually decreased with the migration of tuntian, but this farming method was still retained in remote mountainous areas. With the evolution of production tools from stone knives, stone chisels, stone axes, and wooden sticks to iron knives, hoes, and ploughs, and the planting crops have evolved from single rice to rice, corn, beans, miscellaneous grains, and even sugarcane and oil cash crops. Since 1978, as a result of increasing investment in agriculture, building farmland and water conservancy, implementing fixed cultivated land, and prohibiting deforestation and land reclamation, the primitive production mode of slash-and-burn farming has been basically abolished in border ethnic areas and remote mountainous areas.

Slash-and-burn farming is a remnant of the Neo-Shihu Biqi era. Also known as migration agriculture, it is a primitive farming system.

First with a stone axe, and later with an iron axe, the roots and stems of dead potatoes such as trees on the ground were cut down, and the plants were dried and burned with fire. The burned land becomes soft, does not turn the ground for the age of celery, uses the surface grass ash as fertilizer, no longer fertilizes after sowing, and generally plants for one year and then changes the land.

This actually describes a mode of production and life of primitive human beings. As early as thousands of years ago, when human beings had just completed the transition from animals to humans, the material conditions were very scarce and the living environment was very difficult. Unlike now, you can buy whatever you want and eat directly with money.

At that time, everything was done by yourself, such as hunting to fill your stomach, making your own clothes to keep you warm, designing tools to complete production, and so on. And in the thousands of years of adapting to nature, human beings have gradually mastered the survival skills of slash-and-burn farming.

First, the knife represents the creation of humans and uses tools as mammals, and humans do not have the advantage of size and strength, so they can only rely on group attacks to hunt and hunt. Among them, the invention of various tools has greatly made up for the shortcomings of the weak body. Stone knives and stone axes greatly increase combat effectiveness both for hunting and against the threat of large beasts.

Secondly, sharp knives can improve the efficiency of cutting, making it easier for us to collect timber to build shelter. At the same time, because human beings have transitioned to "cooked food", it is inevitable to deal with food, such as peeling and cutting meat, etc., and the appearance of knives has also facilitated the life of primitive humans. Finally, growing crops such as rice, wheat, etc., requires sharp harvesting tools during the harvest season, and some tools can be used here, such as fish bones, shells, homemade stone sickles, etc.

In short, the knife represents a tool created by human beings, and its emergence has greatly improved the efficiency of production and life.

Second, an important sign of the self-sufficiency of human beings and the guarantee of primitive human survival is to master farming techniques and get rid of the food acquisition method with hunting as the core. This is very importantFirst, learning to farm can effectively reduce the rate of personnel **, after all, there is no need to directly confront the beasts. Second, large-scale crop cultivation can meet people's needs for food without starvation.

Only when we are well fed can human beings reproduce and grow faster.

Third, the use of fire can be guaranteed in many waysThe use of fire is often recognized by the academic community as a sign of human detachment from animal society。Because fire has many benefits, it can avoid the cold, it can be cooked, and it can be used as a means of attack. Think about it, only when you really enter human society will you need to make a fire to keep warm, otherwise you can evolve fur like animals.

The use of fire can also be used to make cooked food, which allows people to get rid of the primitive state of drinking blood and reduce the rate of illness. Of course, after mastering the use of fire, human beings are no longer afraid of any wild beasts, and the safety factor of life is greatly improved. It can be said that fire is the cornerstone on which primitive societies can be built

It tells how some primitive people lived, how they used some things around them, how they developed some tools, and also let us understand some history.

Slash-and-burn farming means that in primitive societies, when the tools for farming were not developed, people would use fire to burn mountains, use ashes as waste materials for crops, and use such land for planting.

It is about a state of life and a mode of life of primitive human beings, and it also tells about the very lack of material conditions at that time, and a mode of production of people at that time.

"Slash-and-lash" refers to the use of various primitive knives to cut down ground vegetation to pioneer; "Tinder" refers to the burning of wood on land and the use of wood ash as fertilizer.

Introduction: When it comes to watches, people are most familiar with them. In the past, we used to see the time through the watch, but now we show our temperament through the watch.

Each watch has its own different meaning and different fashion. There is a wide variety of watches on the market, and each watch has various functions. Of course, the more features there are, the more expensive they are.

1. Content. With the improvement of the quality of life, many people now wear some jewelry to show their charm and fashion outlook. When it comes to a watch, the first thing people see is its dial.

The clear partitioning of the dial allows for a better view. There is also his design concept, style, fashionable, is very popular with people. What's more important is the details, and the details are handled properly, after all, a good product is reflected by the details.

Secondly, simplicity is also a fashion, as the saying goes, a sparrow is small, but it has all the organs. <>

2. Specific. Innovation, innovation is the driving force of development. For a table of innovation, novelty and novelty of design features.

It will be loved by the public. Although he is **, he also contains a classic taste. After all, the classics are also very powerful.

There is also a comfortable wearing and in line with your own temperament. A good watch with a sense of fashion must not only have a good design concept, but also have a good quality assurance. It would be a great decoration.

Some details inside the watch hands and bracelets and dials are well handled, and fashion is also divided into several types, including sports and trendy models. <>

3. Perception. Workmanship is more important in detail and quality. Good details and quality will be more popular with consumers.

If it is said to be very fashionable, but without good workmanship and good quality, it will greatly affect the mood of consumers, and thus affect the next consumption. The second is the classic, which is a classic because it has a special charm. You can be innovative, or you can incorporate some classic design ideas.

Consumers can choose the corresponding style according to their own needs.

Slash-and-burn culture is a manifestation of primitive societies with extremely low levels of productivity. The expression of slash-and-burn culture is spread all over the world. Its outstanding feature is that when people were engaged in agricultural production, they used various primitive knives to cut down ground vegetation to open up the land, and in order to obtain enough fertilizer, they set fire to the mountains and use their ashes to grow crops.

There are still many remote and poor places in the world that retain this backward mode of production. In some places, there is also the custom of "burning fire dung", which is a relic of slash-and-burn culture. The aftermath of its culture is profound.

It's about some agricultural problems, and it's a very real thing, and it's also about using a knife to plow and stones to make fire.

It is about the life of primitive people, the things that primitive people eat, live, hunt, and warm.

It is about the primitive society, where the productive forces are extremely underdeveloped, and when agriculture is carried out, they will use some primitive knives to work, and can use some tinder technology to make delicious food.

It was because the productivity level was relatively low at that time, so people were able to increase the yield of agricultural products in this way, burn the grass on the ground into grass ash, use it as fertilizer, and then dig pits and grow food in the ground.

It is about the way of life of the cave people on the top of the mountain, the survival mode of primitive society, using fire to heat food, farming, and using relatively simple tools to survive.

It is about the development of primitive society, about the process of human beings using tools, and about the process of evolution.

Slash-and-burn farming, a Chinese idiom, pinyin is dāo gēng huǒ zhòng, which means a farming method in ancient times, burning grass on the ground into ashes for fertilizer, and digging pits on the spot to plant.

8.Gradually, the village grew larger, and the thatched grass was constantly retreating outward, leaving only a platform in the middle of the village, where the native thatch was still swaying gracefully.

9.Isn't it the merit of labor that mankind has today's beauty and civilization today?It is labor that allows us to get rid of the living state of wild animals that drink blood, it is labor that allows us to stand upright out of the forest caves and approach the rivers and lakes, and it is labor that allows us to enter human society and social civilization from slash-and-burn farming.

10.At the beginning of this century, there were still some backward areas in the world that were still in the stage of slash-and-burn cultivation on the sidelines and oblique belts.
