Rice cultivation in my country, which has a history of 7,000 years, is the first country in the world to cultivate rice, and the methods of rice cultivation are becoming more advanced and easier for farmers as societies develop and progress。
Sword and fire
Slash tillage, which is meant to be farmed with wood, stone knives or metal-like (bronze)-like instruments, which will ease the land and contribute to the growth and development of crop seeds, such as those used today to climb ploughs and tops. As for the fires, at that time productivity was not sufficiently developed and there was little land, mostly forests, that could be used directly to grow the crops, which would have to be cut down to flat ground. However, the low productivity at the time and the fact that the entire forest had been cut for a long time were such that the ashes of the forest were burned in a fire, which was rich in elements such as potassium, which was more nutritious to the land and more conducive to farming. So that's how people grow food in ancient times。
Let's not talk about ploughing. It's progress in production tools, and today we're talking about modern rice cultivation. Let's see. Maybe you'll find it familiar。
Plug in
Plugging is the most primitive method of seeding rice and, because of the heavy workload, often requires a family. This has led to the development of agricultural characteristics of our finely cultivated country。
Specific methods: it is usually done when seedlings are up to three to five inches long, directly transplanting rice seedlings from the paddy field to the paddy field; it is also possible to plant seedlings directly in the water field, which is the most common method of farming。
There was also a discussion about plugging, the first day of plugging, called "opening the door." the housewife is required to prepare food and wine for the family and helpers; and to eat eggs, meaning “honoring head”. He goes down and pulls up, then sweeps the field with straw, which means preventing “crazy”. At the end of the plug, called “close the door”, some heads of household went around the field, pulled a seedling home and threw it at the door wall, saying, “the seedling recognized the door and the harvest entered it”. At dinner at the end of the day, the host asked for helpers, called “dispersion”. In the field, three meals a day and two snacks。
Drop it
Rice plowing is a new rice seeding technology developed abroad in the 1960s. It has changed the traditional practices of the country's farmers, who for thousands of years have “faced themselves to the ground”, to pull their backs。
Specific methods: rural runoff is divided into two situations, one where seeds that are not fully developed will be thrown into the field; and the other where seedlings are grown and dumped in the field when they are not. The difference is that it throws directly into the field with its hand, saves it even more, and is lighter。
It has the advantage of saving labour, saving energy, saving seeds and fields, being simple, productive, productive and efficient, and is a major reform of rice cultivation technology。
Mechanized seeding
With the development and progress of our economy, agricultural production will also need to be scaled up, and the demands of high productivity will need to be met by mechanization in a time-saving and time-saving manner。
Specific methods: complete full maintenance repairs of the plug-in machine prior to the plug-in, in particular planting arm parts, and remove inspection maintenance to avoid disruption to normal work. Then the line goes straight, the line goes narrow and narrow. A line of plugs should be set aside to facilitate access to the paddy fields, so that they can be fully integrated without the need for a sidewalk. Triple interfaces need to be neat and leaks reduced. In the case of small amounts of water, water should be added to the box to prevent leakage. Five missing slots are to be dropped to fill the saplings and fill them with leakages; leakages, drifting and tasting are to be reduced, with a general permitted leakage rate of five per cent. After the plug is completed, the plug will be cleaned for next use。
We have a long history of rice sowing and feeding millions of chinese, and the methods of sowing will continue to improve as the times unfold
