trồng Lúa trên Mái Nhà ở Trung Quốc và Những Cách Làm Nông Mới Lạ nhất thế giới

Hello everyone, welcome back to the Chả Đá 2K channel. Agriculture is one of the most important areas in human life, providing food to people around the world. Currently, to increase the output of labor in the agricultural sector, as well as saving costs and labor, farmers have applied a lot of new technologies, new methods of cultivation that make us surprised. Along with that is the help of modern machines gradually replacing humans in labor. Right now, let's not let you and your friends wait long, let's go with Chả Đá 2K to find out how farmers have applied science, technology and unique methods of new labor will be effective. Chinese farmers grow rice on the lake, making the whole world admire. In the past, farmers in China surprised the world's agriculture by successfully growing rice on high-rise buildings, which has not been done anywhere else in the world. Now, farmers in China once again make the agricultural science world admire when they successfully grow rice on the vast lake. Even the technology of growing rice on the water surface has been expanded to many places in China, bringing a lot of benefits to the economy and the environment. Because the area of ​​the water surface in the lakes in China is quite large, and the important thing is that the temperature in the water is lower than on the ground. And do you know that in the water sources of the lake river, there is a very suitable amount of fertilizer for rice to grow and develop. To be able to grow rice on the water surface, people will use plastic trays that can float. Above these plastic trays are holes, we just put the wheat inside, then put the pot on the water surface for the rice to grow and develop. The roots of the rice will grow under the surface of the water, ensuring that it can absorb nutrition thoroughly. This method is really very useful, isn't it? It can expand the area of ​​the rice field, while ensuring that the rice is not dry. It also creates an environment for the development of water cyclones, increasing biodiversity in the lake. It is truly a new and effective way of gardening. Growing flowers in normal colors can sometimes be boring, but in the autostadt-wurtberg of Germany, farmers have turned growing flowers into a very eye-catching set of art. When they turned a flower garden into a flower garden, it is beautiful and famous all over the world, attracting many curious tourists to visit and take pictures. This garden has a bridge in the middle, surrounded by yellow flower pots, especially that it can rotate in a circle like a rocket. The rotation is so that the flower pots can touch the water and get moisture from the water below, but it also creates a very new feeling for those who come here for the first time. When you look at this flower garden, do you think of anything? It's like a time lapse, isn't it beautiful? Farmers drive four wheels to plow the land. In Vietnam, the work of plowing the land from afar still happens manually. According to the popular belief that the buffaloes go first and the plowers follow, now that science and technology have developed, there are plowing machines that do this work. But in some places in Canada, farmers without buffaloes do not have cows, and so they use their own carriages to plow instead of buffaloes. This sounds like a waste, but in fact it is very reasonable. Because there are no buffaloes or horses to plow, renting a plowing machine costs a lot in these countries, while the carriages are already in the house. Therefore, farmers have used their own carriages to work instead of buffaloes. Just plowing the grass and then plowing the grass behind the car, then driving the car along the plow, so we can plow the whole garden with just a few tons of gasoline. The result is both fast and cheap, very convenient, right? It is true that doing agriculture in the style of rich people is really fun, but we still feel a bit sad for the car. If only each of us had a car like that, we would keep it and maintain it very carefully, never bring it to the field like this. Using a drone to spray insecticide The work of spraying insecticide as well as insecticide harmful to plants for a long time is still done artificially. Farmers still have to interact directly with toxic chemicals. Now in many places in China and Canada, developed countries around the world and in Vietnam, farmers have applied modern technology to use drones to work hard and hide many dangers. Farmers only have to put insecticide and insecticide under the drone, control it to move around the field. Of course, to be able to control these drones to work effectively, farmers also have to learn how to work and how to control it to work the most effectively. This is not simple for farmers, but compared to spraying insecticide like before, the way to do it is also much more effective and safer. These drones can load up to 100 kg of goods and easily load an adult. Therefore, people also use it to transport crops on remote terrain. The drone will be controlled remotely by a separate handheld device and can be connected to a phone or computer to control remotely. Many of us probably know that in Dubai, the weather is hot and dry, the amount of fresh water is extremely rare, it is the place with the lowest average rainfall in the world. Therefore, to grow vegetables, people have to build straight farms in the largest malls in the world. This is a system for growing vegetables in a glass farm. Inside are trays for growing vegetables arranged into layers, which can be 15 to 20 floors high. Although the area is small, it produces 20 times higher. Inside will be equipped with a foam system along with a light LED system that can control the temperature. When here, the green tree will develop very quickly in an environment controlled by temperature, humidity, water and nutrients. Therefore, it will help the green tree to grow the fastest and best. The largest farm in the world is Bustanica, which can harvest 3.6 tons of vegetables per day in an area of ​​10,000 square meters. The result is too modern and wonderful, isn't it? The world's largest grass cutter can cut 100 tons of fresh grass per day. In farms that raise large milk cows around the world, up to tens of cows, people need tens of tons of fresh grass per day for food. Therefore, there must be a fast and modern to be able to harvest hundreds of tons of grass on dozens of hectares of grass fields. Farmers use a super-fast grass cutter called Kul FC 13460RA with FanOne cutting net technology. This machine is designed in a modular design that can be folded and opened. When it expands the length of the cutter up to 13.4 meters, the machine will move and cut the grass at a speed of up to 30 km per hour to harvest a hectare of grass in just a few minutes. The grass is cut and spread on the field. At this time, there will be another machine to collect the grass and cut it into small pieces. This unique grass-collecting machine has a very special name which is Kul GA 15231. It is capable of collecting 20 hectares of grass per hour thanks to the equipment of up to 6 large rototillers. Each rototiller has a diameter of up to 3 meters. When working, the rototillers can open up to 19 meters wide. They will rotate the grass on the field into small pieces to make it easier to pack the grass later. When we look at this machine to open and harvest its large rototillers, we are reminded of the robot machines that transform in films or movies. It doesn't look like a transforming robot at all. When the grass has been collected into small pieces, there will be another machine to collect and pack. It will pick up the grass on the ground and then put it in the basket. Here, the grass will be pressed tightly so that the basket can contain the most grass. When the grass has been pressed, it will use fabric to wrap these blocks of grass for easy storage. Looking at the scene of this machine using fabric to wrap the blocks of grass, we are reminded of the image of a super huge spider taking the spider web to wrap the mosquito. It's really interesting, right? With such modern machines, combined with the very scientific now we can understand why only with a small amount of labor, people can ensure daily food for tens of thousands of cows. It's really amazing, isn't it? So you have just finished the video about how people apply science and technology to modern machines to make agriculture simple and effective. I am very happy to share with you interesting knowledge about machines as well as new technologies in agriculture. Thank you and see you in the next videos.
