Yang Tuo took this opportunity to return home and compile his own "Nongshu". He hoped to complete this matter before going out for the expedition.
For several months, I have had a rough draft in my mind, and I am just waiting for it to be finalized before it can be written into a book.
For several days, he was organizing his thoughts and preparing to finally write the book.
On this day, he made a bamboo slip from the purple bamboo in the purple bamboo forest. He threw the bamboo slip in the air with both hands and waved his right hand rapidly.
With the movement of his right hand, writings appeared in the air. They were densely packed and flying all over the sky. Yang Tuo pointed his hand, and countless words, carrying Yang Tuo's thoughts, flew into the bamboo slips.
On the bamboo slips, many words appeared, circulating endlessly, and slowly filling up the entire bamboo slips.
When the entire bamboo slip was filled with words, Yang Tuo stopped and wrote the words "Nongshu" on the other side of the bamboo slip.
Since then, the whole book has been completed. It may not be complete, but it is Yang Tuo's hard work, and it can be slowly added and revised in the future.
This book contains a lot of content. It would have taken hundreds of volumes with ordinary bamboo slips, which was too inconvenient, so Yang Tuo made it into a magic weapon and recorded all the contents in just one volume.
Just as Yang Tuo was about to put away the bamboo slips, the wind and clouds in the sky changed color. There was a faint sound of thunder, and there were images of sages floating in the air.
In the Fire Cloud Cave, the Three Sovereigns, Five Emperors and all the sages all set their sights on Xiqi City. Almost all the mighty gods felt this in their hearts.
As soon as this book was completed, the luck of the human race suddenly skyrocketed. Those with great supernatural powers related to the human race could feel the rolling river of the luck of the human race.
In the endless void, a long river of destiny, representing the destiny of humanity, slowly emerged from the void. It contained the destiny of the entire human race, and countless figures appeared from the long river.
But they are the figures of all the saints and sages who have attained enlightenment in the human race for many years. They have been suppressing the fate of the human race. Each one of them is the heritage of the human race, and is the divine needle of Dinghai.
At this time, a huge stream of luck surged out from the long river of luck, followed the induction in the dark, fell from the sky, and fell into the newly formed bamboo slips.
However, when the "Nongshu" was first completed, the luck of the human race increased, and the luck was felt in the long river, and the luck fed back.
The Nongshu is of great benefit to the luck of the human race. It has been blessed by the luck of humanity and has become a spiritual treasure of luck.
Only in the future, when this book is spread all over the world, the luck of humanity increases greatly, and the merits are perfect, and when the merits of humanity decline, then a spiritual treasure of merit will inevitably be born.
Yang Tuo also didn't expect that he just wanted to make some contributions to the development of the human race, but he didn't expect that this book would have such a big impact.
But he underestimated the role of agriculture in the development of humankind.
Since Emperor Shennong passed down the grains, humankind has experienced long-term development. It can no longer rely on the natural world to obtain food.
The development of agriculture has enabled the human race to feed more people and have reserves to resist disasters, so that they will not be easily defeated by natural disasters.
This is also one of the reasons why the human race can rise from all races in the wild.
Yang Tuo's "Agricultural Book" is divided into more than 60 volumes and is rich in content. It covers 12 topics including agricultural basics, land system, farming, water conservancy, agricultural equipment, arboriculture, sericulture, planting, animal husbandry, manufacturing, waste preparation, and diet.
.
Among them, agricultural science mainly expounds the agricultural-oriented thinking, as well as seed selection, improvement, seedling cultivation, etc.
The land system introduces the basic situation and advantages and disadvantages of the well-field system, the farmland system, the land occupation system, the equal land system, the divided land system and other systems.
It was also formulated that patients with fertile soil and no worries about floods and droughts are considered to be of the highest grade; those with fertile soil but suffering from floods and droughts, but those with fertile soil but without concerns of floods and droughts are considered to be of the middle grade; those who are both fertile and suffering from floods and drought are considered to be of the lower grade. .
And the land is allocated according to the upper, middle and lower grades. For example, the top grade requires 100 acres, the middle grade requires 150 acres, and the low grade requires 200 acres. Then, taxes are collected according to the standard of 100 acres, which is used to eliminate the reasons for the superiority of the land. The difference caused by inferiority.
He also recorded a series of systems such as the sharing of land and land, many of which are not suitable for today, but Yang Tuo still recorded them.
Farming records various activities of agricultural production, guiding farmers to cultivate intensively, better planting, weeding, pest control, fertilization and many other techniques.
Water conservancy records irrigation, flood control, drought relief and other matters.
Agricultural tools introduce various tools used in agricultural production and configure diagrams.
Arboriculture introduces the planting and cultivation of saplings, etc., including a series of techniques such as pruning, grafting, and transplanting seedlings.
Sericulture records various aspects of silkworm rearing and weaving.
Planting records the planting techniques and differences of various crops.
Husbandry records the raising of livestock and the breeding of poultry and fish, increasing the food choices of the human race.
Manufacturing records the manufacturing and improvement methods of various agricultural equipment, as well as its role in promoting agricultural production.
Preparing for disasters introduces how to store, how to fight against pests and diseases, and how to defend against various natural and man-made disasters.
Diet introduces many edible plants, as well as healthy eating methods and habits. The edible types are recorded one by one.
This book contains a lot of agricultural knowledge that Yang Tuo will know in the future. Many of them are not suitable for the current situation. We can only select and disseminate appropriate knowledge according to the progress of the times.
This "Book of Agriculture" records all aspects, except for the time of day. This time of day is the most difficult to identify, and after becoming a god, natural phenomena such as wind, rain, thunder, and lightning between heaven and earth are under the jurisdiction of heaven, and human beings have no control at all. Seize the opportunity.
But one thing is that although today's world is divided into four seasons: spring, summer, autumn and winter, there are no twenty-four solar terms to guide agricultural production.
The human race cannot control the celestial phenomena, nor can it be limited by the celestial phenomena.
Yang Tuo decided to formulate the twenty-four solar terms to complement the movement of heaven. Let the people know when and what to do, and no longer need to rely on the experience of the elderly to judge.
Experience is sometimes not so accurate. For example, if you sow seeds late, the harvest will definitely be affected.
However, the division of the twenty-four solar terms is not that easy. You need to first determine the four solar terms of the spring equinox, summer solstice, autumnal equinox, and winter solstice.
By measuring the length of the solar corona's shadow, the day with the longest day of the year is designated as the summer solstice, the day with the shortest day is designated as the winter solstice, and the two days of equal length day and night are used to determine the vernal and autumnal equinoxes respectively.
Then based on this, the year is divided into twenty-four equal parts. There are six solar terms in each season of spring, summer, autumn and winter, and two solar terms in a month.
They are:
Beginning of Spring, Rain, Waking of Insects, Spring Equinox, Tomb Sweeping Day, Grain Rain,
Beginning of summer, Xiaoman, Mangzhong, Summer Solstice, Minor Heat, Great Heat,
Beginning of autumn, end of heat, white dew, autumnal equinox, cold dew, frost,
Beginning of winter, light snow, heavy snow, winter solstice, light cold, big cold.
Among them, the beginning of spring, the beginning of summer, the beginning of autumn, and the beginning of winter are the beginnings of the four seasons.
It will take several years to observe, summarize, and finally formulate a complete solar term schedule.
But now that the expedition is about to begin, there is no time. However, Yang Tuo still made a small sundial to observe and summarize the rules.
Yang Tuo let out a long breath and looked at the purple bamboo slips in front of him. With this agricultural book completed, the luck of the human race has increased a lot, and Yang Tuo's luck has also received a lot of feedback.
The commotion just now was really quite big. I didn't expect that a small scroll of letters would cause such a big commotion.
