Datang Nongsheng

Chapter 152
The melting point of crystal ore is above 1700 degrees, while the temperature of ordinary charcoal is only about 1700 degrees. Even coal, it is difficult to reach 2300 degrees. Therefore, if you want to refine crystals, you must first reach the temperature of [-] degrees. Get out the coking coal.

There are not many places to produce coal in Guanzhong, and due to technical reasons, mining non-open-pit coal mines in this period requires a lot of manpower and material resources, and the investment is very huge. Sun Xiangfu does not expect Li Shimin to invest money in this. Usually he invests money , the benefits belong to him, so it will be more reliable to cooperate with the Wei family, who was originally the landlord of Guanlong.

Sun Xiangfu knew that once the coal business started, the profits would be huge, and the impact would also be huge.You must know that there are at least tens of thousands of households in the Guanzhong area who rely on firewood and charcoal to help their families. If they can't solve the problem of food for these people, he rashly created a coal industry, which may harm these tens of thousands of households.

However, business matters are not easy to talk about on board, and only after on-site surveys can we negotiate and plan in detail. Therefore, Sun Xiangfu only expressed an intention with Wei Shuxie. After all, apart from cooperating with the emperor and the seven clans and five surnames However, Sun Xiangfu had no choice but to cooperate with the Guanlong family, so that this matter could be done.

Newly rising nobles like Qin Qiong, Cheng Yaojin, and Yu Chigong just have some fields around Chang'an. Unlike the Guanlong family, there are few who have a county territory, and many who even have half a state, or even a whole country. The Yang family in Hongnong is an example in the prefecture. In the whole Hongnong County, if you want to do big things, you can't think twice. Li Shimin had to accept their Yang family's daughter as a concubine in order to gain their support.

Carrying heavy cargo, the fleet moves slowly. Although the Happiness is not affected by the monsoon and upstream, but there are two imperial envoys on board, they cannot leave the large team and go alone. Therefore, they walked slowly for ten minutes. A few days later, the fleet arrived in Yangzhou, and at this time, the autumn harvest was in progress in Guanzhong.

Early in the morning, a group of flying cavalry rushed to Huangzhuang in Lantian County. Here, there was a piece of land cultivated by Li Shimin Chunshang himself. , he did not forget the matter.

To do a show is to do a full set. I taught the crown prince and several princes to sow, and naturally they also have to teach them to harvest. Therefore, today Li Shimin did not come alone. The crown prince, Wu Wang Li Ke, Pu Wang Li Tai, Qi Wang Li You and Liang Wang Limin.

"Father, this is the field. I remember, look, the wheat here is taller and stronger than the field next to it, and the ears of wheat are very full." Li Chengqian is more concerned about things related to Sun Xiangfu, After walking to the edge of the field, he pointed to the wheat in the field and said, of course, these words were taught to him by Chang Sun Chong long ago.

"Well, I know, you five brothers, let's harvest these few acres of wheat today!" Li Shimin nodded casually when he heard the words.

Cutting wheat stubble with a sickle is indeed not technically difficult, and children can do it, but it is a bit difficult for these children to cut a few acres of land. Li Chengqian is the oldest, and he didn't feel it at first. No, I wanted to complain, but Li Shimin, who was standing on the ridge of the field, was discussing things with his eldest grandson Wuji, Xiao Yu, Wei Zheng and others, and he couldn't interrupt.

Of course, there are others who are even more unbearable than him. The youngest Li You and Li Yin cut a few times indiscriminately, then sat down in the field and chased and killed the reptiles in the field with a sickle, serving their servants. In this situation, he found a gap and said to Li Shimin, "Your Majesty, the crown prince and the other princes are still too young to do this rough work, so let the servants do it for them!"

"Hmph, some worthless guys, now you know the truth of 'every grain is hard work'! Watch it from the sidelines."

Li Shimin specially wore tight clothes designed by Sun Xiangfu's tailoring workshop today. He didn't need to tie his hem around his waist, and he didn't need to tie his sleeves tightly. Seeing Li Shimin going to the field, they all came over and bent over to cut the wheat.

Their sickles are made of fine iron, so they can cut very quickly. However, they are only responsible for cutting down. As for tidying up, naturally there are servants to take care of it. In less than half an hour, the six acres of wheat fields have been cut by several people, and the servants have already cut it down. Most of the wheat tax was broken into granules and piled up on a piece of hemp cloth.

"The wheat produced here should be [-] to [-] percent more than other fields." Wei Zheng reckoned looking at the pile of wheat that was half a person's height.

"It's more than that. There is a drought in Guanzhong this year, and the crop yield is not high. The yield of the first-class fertile land is rarely more than two stones per mu, the middle field is only one and a half stones, and the lower field is even less. , at least three to four percent higher."

Changsun Wuji, who is in charge of the household department, has a clear picture of the output of Guanzhong's farmland. In fact, he has already said it according to his good intentions. This year's wheat production in Guanzhong has not exceeded two stones, and at least [-] to [-]% of the crops have not been harvested.

"How much is the yield per mu, I will know after we weigh it."

After Li Shimin said that, some servants set up the weighing pole, and the cloth bags sewn in advance filled a bag of wheat and weighed each bag. After a few servants picked up all the wheat on the ears of wheat into granules, it was basically called It's over.

"Your Majesty, a total of three thousand one hundred and twenty-seven catties."

"How many?"

"Three thousand 120 seven catties."

"There are so many? I remember, it seems that there are only six acres of land. Doesn't it mean that the yield per mu has reached four stones?" Wei Zheng was a little dazed.

"Wei Qing's calculation is wrong. It should be more than four stones and three per mu." Li Chengqian, who was watching the excitement, interjected.

Hearing the words, Wei Zheng calculated silently in his heart. It is true that his mental arithmetic is not as accurate as that of a child. He immediately cupped his hands and said to Li Chengqian, "The prince is smart, and he is even more proficient in arithmetic than the old minister. The old minister admires him."

A child like Li Chengqian who loves to show off likes to hear other people's praise the most, and he smiled happily when he heard the words, "It's nothing, Gu Na junior sister Hou Shuya is amazing! However, it is said that the Sun's family has even more powerful ones. Dharma formulas, they can all recite them backwards."

"Hmph, then Sun Zhengming was born to be a profit-seeking person who only cares about pennies and pennies. He specializes in the way of mathematics. He has such good reading conditions, so he doesn't read much about sages and gentlemen." Li Shimin said reflexively, Because of the bet, people who lose will not be in a good mood.However, he suddenly remembered what Li Chengqian said just now, turned his head to look at Li Chengqian and asked, "What is the yield per mu?"

"Father, it's four stones and three or more." Li Chengqian didn't know why Li Shimin suddenly lost his temper, but luckily he didn't attack him, so he answered casually.

"Four stones and three? There are four stones and three?" Li Shimin was stunned. Even in a year with good weather, it is difficult for the upper field in Guanzhong to produce three stones of wheat. This field actually produced four stones and three wheat in a year of slight drought. ,How can this be?

One mu of land can produce [-] catties of wheat, which is still the wet weight of just harvested. In later generations, this is not an achievement at all. With the same area of ​​land, in future generations, any farmer can grow [-] to [-] catties of dry wheat. It can be [-]% to [-]% higher than this output, but this data is indeed a bit unbelievable to the ancients. For the first time, Li Shimin felt that farming is actually a high-tech job.

"Your Majesty, please publish the planting method of this field and inform the people all over the world. This is the method that God blesses us to make the Tang Dynasty prosperous." After figuring out the meaning of this number, Wei Zheng said excitedly.

"Post the list, post the list, hey, in fact, there is no need to post the list. This method of planting is written in "Qi Min Yao Shu", and I didn't pay attention to this book before." Li Shimin said a little annoyed.

The book "Qimin Yaoshu" actually has quite scientific records on the crops suitable for growth in the Central Plains and the method of whole field cultivation, almost reaching the limit level of the conditions that can be achieved in this period.

Not only that, but he also has very comprehensive records on all aspects of farming and people's livelihood development, such as planting trees, raising livestock, poultry, brewing, and cooking.

And people who have read this book thoroughly and learned everything, in this era, can definitely make a fortune easily. Even the planting techniques used by Sun Xiangfu now generally do not exceed the things recorded in "Qi Min Yao Shu" How many.

Li Shimin is now a regret!If at the beginning of the founding of the Tang Dynasty, the common people could produce according to the farming and breeding methods recorded in "Qi Min Yao Shu", then the current national strength of the Tang Dynasty could at least be multiplied several times.

But now, he can explain so many farming skills from Sun Xiangfu. It turns out that this guy has learned all of "Qi Min Yao Shu".

""Qi Min Yao Shu"? After I go back, I must study this book carefully." Wei Zheng heard that he seemed to have remembered such a book, but ancient scholars had the idea of ​​chasing ancient times, and felt that the more ancient it was handed down The classics are more wise and famous, so they pay less attention to the books written in modern times. There are also reasons why scholars look down on farming books. Those who can read "Qi Min Yao Shu" prove that they have already had a high degree of knowledge. How could it be possible to do something like mud legs like farming, the arrogance of scholars does not allow them to do this.

Of course, there is also the issue of information circulation. The promotion of a book in this period is not like the era when the Internet and printing were popularized in later generations. In the early Tang Dynasty when engraving and printing were not widely used, hand-copying was often required for one-on-one According to legend, it will take decades at least to popularize such a speed.

"Qi Min Yao Shu" was written in the last years of the Northern Wei Dynasty, and it has only been a few decades. Naturally, it has not been widely popularized, let alone applied.In fact, in the Song Dynasty, there were many agricultural books based on "Qi Min Yao Shu", and its benefits gradually began to be brought into play. It became popular in the Song Dynasty, when the literacy rate of the people was high, and the farming business at that time began. Gradually shift to intensive cultivation.

Sun Xiangfu demonstrated to Li Shimin the benefits of intensive farming with examples, and the first result was that Chang'an's "Qi Min Yao Shu" was almost sold out of print.

No way, in the era when movable type printing was not popular and most books were still bamboo slips, such long paper books were very rare and expensive. When everyone was looking for a book, this news could no longer be hidden up.

Inugami Ertian's dog's nose is very sensitive. His purpose of coming to Datang is to learn all kinds of techniques. How important is a practical book that teaches everyone how to improve the output of the field? How could he not know.

Moreover, it is now rumored in Chang'an that planting wheat according to the records in this book can double the yield. Therefore, Inugami Ertasu went crazy and bought a book without hesitating a thousand taels of silver, and spent a lot of money to find it. Many people who can write help him to copy books.

Sun Xiangfu didn't know what happened in Chang'an, and he didn't know that his so-called talent was greatly discounted by Li Shimin, because Li Shimin felt that he was going to mass-produce talents like Sun Xiangfu who were good at farming.

In the Palace of Lizheng, Li Shimin thought for a long time before saying to his eldest grandson Wuyou, "Guanyin maidservant, I am going to ennoble Sun Zhengming."

Hearing this, Changsun Wuyou was taken aback for a moment, then cast a questioning look at Li Shimin and said, "Why?"

Li Shimin made up his own reasons and said, "He has made too much contribution to introducing rice seeds to the south this time, and I can't suppress it. Moreover, I have already found a talent who can replace him in the management of Huangzhuang."

Hearing this, Changsun Wuyou was a little surprised, and continued to ask, "Who is it?"

"Anyone who is proficient in this book is welcome." Li Shimin shook the "Qi Min Yao Shu" in his hand and said.

After he came back, Li Shimin picked up this book again and started to read. The more he read it seriously, the more he found the beauty of this book. The book that guides the development of people's livelihood is actually no worse than those books that write about human principles. The book should be a must-read for every local official.
