"As early as when the Confucian scholars thought that the past was not the present, we discussed that the world is gradually changing, and it is always better than the ancient, there are Chao's wood for the nest, the Suiren's drill the flint to make fire, the Fuxi's knotted rope and the net, and the tenant to fish, those ancient holy kings' era, people still don't know about farming, let alone animal husbandry, in addition to standing upright cooked food, will use tools, and have a little shame to know that in addition to covering shame, in fact, it is no different from birds and beasts......"

Drinking too much last night, Ye Zijin intimately prepared a weak millet porridge for Heifu and them today, the yellow corn was in the bowl, exuding a fragrance, Heifu pointed to the head of the five grains, and said to Zhang Cang:

In short, people at that time could only fish, hunt, fish and beasts to satisfy their hunger, and they were hungry all year round. Over time, after Shennong tasted the herbs, he began to pick wild fruits and vegetables to make up for the lack of meat, but this was still unreliable and came and went. So when it comes to the back crop, the grass and trees are planted nearby, so that they can be harvested stably every year, which is the beginning of farming! ”

How to obtain a stable and reliable source of food has become the driving force for the origin of agriculture. This process must have lasted for thousands of years and tens of thousands of years, but in order to make Zhang Cang understand, Heifu could only give all the credit to Houji according to the history books.

"Houji learned to plant millet, suitable for the land, taught the people to crop, arboriculture grains, the grains are ripe and the people breed, so the millet is also called millet, and Houji is also respected as the god of agriculture......"

"As we all know, the five vegetables all come from wild vegetables, and the celery we eat today is often wild on the edge of Yunmengze, but do you know where the corn we eat today originally came from?"

Although Zhang Cang was erudite, he had never gone to the field himself after all, so he clapped his hands and asked his subordinates to come up with a book, and when he opened the pages, there was a dry plant in it......

"If it's spring and summer, I'm going to personally drag you to the field to identify, but now in the cold winter, the grass is withering, and I can't see it in the wild, but I went to the farmer's field a few months ago to inspect and let people pick a few plants back, you see, this is the ancestor of corn!"

Zhang Cang looked at it, and the plant specimen that had been sandwiched between the pages of the paper for a long time and became a little flattened, it had long ears and looked like a dog's tail......

"Isn't this the common dogtail grass on the ridges!?"

Zhang Cang was shocked, and looked down at the millet porridge in the bowl in disbelief: "You mean, this millet is made from dogtail grass!?" ”

"He is worthy of being born in a rich family, and he has never suffered from famine."

Heifu laughed at his reaction: "You can go to the people and ask about it, if there is a great famine year, the grain is exhausted, and sometimes people have to rely on the dogtail grass in the field to come over, and the taste is really similar to corn." ”

Zhang Cang nodded ignorantly, he had no worries about food and clothing since he was a child, and he was generous, but he had also seen the famine in the Wei Kingdom. Wei's disaster relief system was said by King Hui of Wei and Mencius: "If Hanoi is fierce, its people will be in the east of the river, and its millet will be moved to Hanoi."

Later, Hedong and Hanoi were lost, and even if the Wei people of Daliang were about to starve to death, they could only stay up on the spot, in that case, not to mention the dog's tail grass, it was easy to eat, and even grabbed the clay on the ground and stuffed it into the mouth, which was also a common thing......

"At least after Qin destroyed Wei, there was no famine in Liangdi, and no one ate people."

Zhang Cang sighed, and then looked down carefully, although the ears of the dog's tail grass were dry and thin, they were really a bit similar to the ears of millet, and the stems and leaves were almost identical.

He was kind of convinced.

Heifu continued to destroy Zhang Cang's three views: the ancestor of rice is the barnyard grass, which is very similar to the appearance of rice, and also grows around the rice field.

The ancestors of millet may have been paving millet or wild millet, and wheat is not said because it came from the west, but degraded wheat will also turn back into wild wheat. The ancestor of the soybean is the wild soybean, the pod is very flat, and the particles inside are as small as a needle......

Anyway, the ancestors of the five grains are all common weeds in the field, and the farmers hate them when they farm, so they must be eliminated quickly!

Zhang Cang was surprised: "Now that the ears of grain are big and full, how did it change?" ”

"It's very simple, even in the dog's tail grass, there is a big one, and it tastes good. The ancients, perhaps really the Houji, selected it, planted it, and watered it often, so that a seed gave birth to ten, ten grains to hundreds, hundreds to thousands, thousands, and finally spread all over the world, and it became five grains, and its brothers and relatives were still weeds. ”

Heifu smiled: "Just like the farmer recently selected a small wild woad to grow a big tripe, this is domestication!" The ancients also said that a year's plan is like a tree valley. Ten years of planning, such as trees, citrus and other fruit trees, have also been domesticated, don't look at Nanjun citrus as sweet as honey, this is the result of breeding, how sour wild citrus is, only those who have eaten it know ......"

Well, heredity and variation, natural selection, artificial selection, these middle school biological knowledge, for the ancients are too complicated and profound, let's not tell Zhang Cang for the time being, just show him the method of seed selection that every old farmer knows.

This is the history of human development of agriculture, the cultivation of grains and other plants at the same time, the world has also domesticated a lot of animals, pigs, cattle, sheep, horses, chickens, dogs these six animals are like this - unfortunately, this year the Central Plains of the "cat" is still only the native raccoon cat, wild still, will only be honest to catch mice will not be arrogant, the Middle East and West Asia cats have not yet been introduced, it is still too early to become a real cat master.

In addition to domesticating animals and plants, people gradually learned to transform the natural environment to make it suitable for agricultural production, Dayu water control is the most typical example. Nowadays, water conservancy has become the most enthusiastic thing in the Qin Dynasty, and there are countless irrigation areas in Dujiangyan, Zhengguo Canal, and Tuntian at the eastern foot of Helan Mountain......

"At present, even a rural farmer who does not know how to read big words knows that in the spring he has to dig ditches and let the water flow moisten the fields, so that the crops can be abundant. Instead of idleness, counting on the fields to be ploughed, ploughed or dunged, and relying on the dogtail grass and wild rice that they grow to satisfy their hunger......"

After saying all this, Heifu said: "Now, do you understand, how to apply Xun Qing's heavenly theory to agriculture?" ”

Zhang Cang bowed his head: "Understood!" In the past thousands of years, tens of thousands of years, from the legendary ancient sage king to today's old farmers and nurseries, what they have done has repeatedly verified my master's words! ”

"Thinking about it in the sky, who should control it with things and animals?"

Zhang Cang's eyes were blazing, and Xunzi's words blurted out, loud and loud!

Instead of blindly worshipping the heavens and thinking of him, how can it be compared to treating the heavens as animals and making them animals?

Instead of blindly allowing things to grow naturally and hoping for them to increase, how can we use human intelligence to help them reproduce?

Instead of blindly hoping for a good harvest and waiting for a good harvest, how can it be compared to the change of seasons and promote a good harvest?

Instead of blindly obeying the heavens and singing its praises, how can it be better to grasp its laws and use them?

"That's right!"

"This is the truth that I hope can be told to the peasants in the newly opened agronomic school of the imperial court!" These thousands of years of simple truth, but now it has been named in the name of the will of the ghosts and gods, and has lost its original face, and now, it must be re-recognized by the world, and continue to be passed on in agriculture! ”

"Know nature, use nature, transform nature! If the sky doesn't give it, people will fight for it themselves! This is the true meaning of farming, and it is also the mission of the human body as the soul of all things! ”

……

"Why do plants grow and grow bigger because of the soil, the air, the water, or the sunlight? You can go down and think about this question yourself......"

When bidding farewell to Zhang Cang, Heifu didn't forget to throw him a small question, which made the fat man continue to be distressed.

When he returned to the living room, he finally had a rare relaxation and began to tease his eldest son, who was born in the twenty-ninth year of Qin Shi Huang, and is now three years old.

Under the guidance of Heifu, the wood of different shapes was slowly piled up, but the child was also eccentric, and when he reached a certain height, he would violently push the blocks down, and then clapped his hands, and looked at his father giggling, as if enjoying the joy that the process brought him.

"You son, I'm afraid I'm going to have to demolish a lot of houses in the future." Heifu shook his head helplessly, but he took the trouble to rebuild the blocks, accompany his son to repeat the game over and over again, and he was extremely patient with the child.

Ye Zijin, who had a big belly, sat gently on the side, looking at the father and son, she was smiling, but when Heifu looked over, he found that his wife's eyes were worried, and she wanted to speak and stopped, as if she had something to say......
