Hidden dragon can not use, see the dragon in the field, Dragon regrets the scientific explanation
In the distant era more than 5,000 years ago, the ancient Chinese who originated in the Yellow River basin, from the fishing and hunting era to the agricultural era, a large number of Li people lived on farming. The wise ancient ancestors were before they survived. Under the title, nature has developed a detailed observation of nature and survival tips for the agricultural life of "seeing the sky and eating". The tens of thousands of people who used farming as a business in ancient China have taken the natural ecology for granted. Observing "deep-to-the-minute" observations. Of course, there is only one purpose for such observations, that is, through long-term experience and observation, to find a set of survival rules that coexist with nature, and help crops grow in harvest, so that everyone can live. Comfortable life.
This kind of expectation, in the research of Master Chen Yikui, found that after entering the Zhou Dynasty, there was a major breakthrough. In the Zhou Dynasty, people finally mastered the "survival code" of coexisting with nature!
Master Chen Yikui discovered that after studying the Book of Changes and ancient books for a long time, he observed that people in the Zhou Dynasty had already noticed a weather that was critical to farming and harvest. The land is always thriving with vegetation. The land is fertile and green, and full of vitality everywhere. As long as you cultivate in this environment, you can often get a pleasing harvest.
Master Chen Yikui even asserted that this theory is actually the earliest record of the discovery of "thunderstorm nitrogen fertilizer" in the history of all civilization development in the world!
How is "dragon" described in the Zhouyi? In the Qian Gua of the Book of Changes, there are the following descriptions of "dragon":
First-nine , hidden dragon do not use.
Nine-two, see the dragon in the field, see the gentleman
Nine Five, the flying dragon is in the sky, see your gentleman
Last nine, Highest dragon has regrets
And in the Gua of Kun, there is also a record of "dragon fighting in the wild, its blood is black and yellow".
If these descriptions have not been deciphered, they always seem to be difficult, incomprehensible, and illusory. Many scholars from ancient times to the present have different opinions. Everyone has opinions, but no one has a conclusion. However, if you quote Master Chen Yikui's theory that "dragon" is equivalent to "thunder", a clear image of ancient people coexisting and prospering with nature will emerge clearly.
"Qianlong" refers to the dry land that has not yet thundered or rained. In fact, since ancient times, Chinese Han culture has always associated the phenomenon of thunder and lightning with the "dragon". There was a person in the Han Dynasty who did not believe in myths. Wang Chong pointed out many misguided theories in his "On Heng", but in this book he also said: "When the dragon sees, the clouds and the rain will reach, and the clouds and the rain will strike thunder and lightning." He also said: "Dragons, fish kinds, it rides on thunder and lightning, but it also flies like a fish."
Therefore, on the whole, the true meaning of "Don't use Qianlong" is deciphered as "the sky is dry and everything is dry, and the earth has never had thunderstorms (Qianlong). Such an area is not suitable for people to use as a place for settlement and farming." (Don’t use it.) Master Chen Yikui believes that areas like the Gobi Desert, or the dry land in the northwestern region where there is no thunder and rain for many years, where no vegetation grows, and the soil turns to sand. Of course, they are areas that are not suitable for farming. A good example is " Qianlong, don’t use it".
So, what does "see the dragon in the field" mean?
When ancient science was underdeveloped and people's insights and concepts were limited, they did not understand the true causes of various natural phenomena, so it is understandable to use different symbols to represent them. Strips of lightning appeared in the sky, followed by heavy rain. The ancients observed and imagined that a mysterious dragon came from the sky. This association is understandable.
Therefore, the real explanation of "seeing the dragon in the field" and "flying dragon in the sky" is "the sky suddenly crossed the fields of farmland and residential areas, thunder rumbling, and heavy rain began to fall." What came was the emergence of fertile land, and a huge harvest was obtained after cultivation.
Why is it that as long as "seeing the dragon in the field" and "the flying dragon in the sky" can turn the barren land into rich fertile soil, so that people can enjoy the fruits of the harvest?
Master Chen Yikui pointed out that the real mystery lies in the role of "nitrogen fertilizer."
In the atmosphere of the earth, there is approximately one-fifth of oxygen and four-fifths of nitrogen. Although nitrogen occupies a high proportion of the atmosphere, it is a fairly stable gas. It is not easy to volatilize, and it is not easy to interact with lively oxygen. It can be said to be a "silent majority." Because it has this characteristic, under normal circumstances, it is not easy to interact with the world and everything, and its influence on the thousands of creatures in nature becomes of little importance.
But when the sky begins to thunder and lightning, this state will begin to change, because when thunder and lightning begin to appear, an electrified state is formed in the sky, and the originally stable and inactive nitrogen will become "active." , Began to become a lively characteristic.
In such an active state, nitrogen will react with oxygen to produce a phenomenon of combustion, forming "nitrogen dioxide." And this kind of chemical effect, as the voltage in the atmosphere is higher, the effect becomes more obvious, and the more nitrogen dioxide is produced.
This kind of "nitrogen dioxide is formed by the action of nitrogen and oxygen" is a well-known experiment in the field of chemistry, and it is a phenomenon that can be easily verified.
If it rains at this time, the nitrogen dioxide formed by the chemical combination in the air will quickly dissolve in the rainwater, combine again to form "nitric acid", and fall on the ground with the rain.
When nitric acid falls on the soil where it rains heavily, it will seep into the soil and form "nitrates." At this time, what is formed is the best fertilizer for the growth of crops on the earth: "nitrogen fertilizer."
So far, because of thunder, lightning, and rain, the whole process of forming fertile soil has been formed like this.
