What are the advantages and disadvantages of mechanization of rice planting?

As we all know, China is a country with a large population and a big rice country. When it comes to rice cultivation, we will definitely think of an old man, that is Grandpa Yuan Longping. Yuan Longping appeared in our textbooks when we were very young. We all know that China can only eat enough, because he has others. He's from China? Father of hybrid rice? Also known as? The catcher in the rice field? . Yes, Yuan Longping is a pioneer and leader in the field of hybrid rice research. He devoted himself to the research, application and popularization of hybrid rice technology. He founded the technical system of super hybrid rice? It is because of hybrid rice that the people of China can have enough to eat in just a few decades.

The large-scale production of rice in China can be realized not only because of the hybrid rice system, but also because of the mechanization of rice planting. So, what are the advantages and disadvantages of rice planting mechanization?

First of all, talk about the advantages of mechanization. Do you think the farmers are still there? Facing the loess and facing the sky? Bend over and plant seedlings for a day? Not anymore. Many farms have? Unmanned farm? Now, every step required for planting is no longer manual operation, but is replaced by machinery. For example, unmanned rice dry direct seeding machine is used for sowing; Like fertilization, unmanned helicopters are used to fertilize and remove pests. When the harvest is good, use the harvester and the grain truck to complete the harvest. Is it convenient? The mechanization of rice planting liberates human hands and improves people's efficiency. In the past, farmers could only manage a few acres of land, but now it is different. As long as you master the technology, one person can manage hundreds of acres.

Let's talk about the disadvantages of mechanization. First of all, at present, the occupation of farmers in China is still done by the elderly in rural areas, so it is difficult to develop into mechanized operations as a whole, because the knowledge and education level of the elderly are not very high. Secondly, we should consider whether all terrain is suitable for mechanization. If the terrain is not very flat, it is not suitable. So mechanization also has certain limitations.
