Li Shimin in history often said that 'taking people as a mirror can show gains and losses', this mirror is Wei Zheng, it can be seen that in terms of personal morality, he is a frank gentleman.

In addition to being fair and strict, loyal and upright, Wei Renjing also has a characteristic, that is, he did not put himself in a high position and look down on all beings like other scholar classes.

On the contrary, he was very concerned about the production and living of the common people, which was also the reason why Li Shimin looked at him differently among the many old parties of Li Jiancheng.

Therefore, the people's harvest is good, Wei Zheng is happy in his heart, he has been in the court to instigate everyone, including Li Shimin, but he has never instigated Sun Xiangfu after becoming a courtier, of course, before Sun Xiangfu became a courtier, he was instigated several times, and the target was Li Shimin behind Sun Xiangfu.

"The output of four stones is definitely no problem, and on the side of the test field, more than five stones is also proper, as for the higher, I dare not say that it is too full."

The yield of five stones, almost 600 catties, even if because the size of the field is more than 100 catties smaller than that of later generations, but with more than 100 percent of the yield, it is less than 700 catties, in later generations, this is a low yield, when Sun Xiangfu came through, most of the mu yield of wheat in China has reached 1,000 catties per mu, high-yield fields, can reach 12,300 catties, and the experimental field has reached more than 1,400 catties, the gap is actually very large.

In the fifties of the twentieth century, that is, in the early days of the founding of the People's Republic of China, it was basically every family farmed, every household kept seeds, and seed breeding was not systematic.

In the sixties and seventies, the "self-selection, self-breeding, self-retention, and self-use" began to be adopted, supplemented by some calculations similar to those used by Sun Xiangfu at the beginning, and the means of vernalization stage were relatively large, and the output was greatly improved.

At the end of the 20th century, there were two main methods of wheat seed production in China, the "three-nursery system" and the "one-nursery system".

The wheat seeds that Sun Xiangfu provided to Guanzhong this year are the seeds he cultivated using the "three-year three-nursery system" breeding technology that was popularized and popularized in the 90s.

The technical points of the three-nursery system are single plant selection, line comparison, and mixed breeding.

The seeds cultivated by the three-year three-nursery system have almost increased the yield of wheat to the extreme under the existing conditions, such as the two-year two-nursery system and the one-nursery system, which only omitted some strain comparison procedures in the breeding process, and there is no increase in yield.

Later, he will also promote the four-level seed technology program, so that as long as the impurity prevention and purity are achieved, the genetic stability of the original variety can be maintained, so that the people can keep the yield even if they keep their own seeds, as for what is called the four-level program, except for the children of the farmer, no one knows this period, that is, the breeder's seed, the original seed, the original seed, and the final good seed.

Starting from breeder seeds to multiplying field seeds, the whole process is repeated, which is a method that can maintain the genetic stability of the original variety population indefinitely, and is also applicable to some other crops, such as self-pollinated rice, soybeans, and eggplants.

Cross-pollinated rape, Chinese cabbage, kale, cucumber, watermelon.

Cotton that is often cross-pollinated, as well as tomatoes, corn, peppers and other crops that have not yet been introduced by Datang at this time, can use this set of four-level degrees to enhance the stability of seed breeding and gradually increase the yield.

Sun Xiangfu was born in the era of science and technology, and, in later generations, he is specialized in the study of these things, these technologies, he is very proficient, only need someone to do it according to his requirements, it can be absolutely realized, his other specialties are half-baked, but the diploma of the graduate student of the University of Agricultural Science and Technology is real.

Of course, in addition to seeds, the yield in the field, mainly depends on planting, this year, most of the fields have been applied with organic fertilizer, in terms of fertility of the land, has been very close to the fields of later generations, as long as the people take care of the diligent, water, sunshine and other conditions are good, the yield may not be lost to the future generations, at least, Sun Xiangfu, who had planted a wheat experimental field in the later generations, personally commanded the management of the experimental field, is not inferior to the yield of the fields planted by ordinary farmers in later generations.

"Hahaha, the old man hopes that the more the people's fields produce, the better, but those grain merchants are afraid that they will scold you behind their backs."

Wei Zheng laughed heartily and answered, but many officials looked at Sun Xiangfu with a very agreeing expression, it seems that these people should all have grain and rice shops in their families.

"The output is high, the supply is sufficient, those grain merchants should thank me, how can they scold me!

Food is a good thing, it produces more, not only can fill people's stomachs, it is also a lot of raw materials for money-making goods, I heard that you like to make wine, after more food, you can brew wine, transform food into wine, its value, can be doubled. ”

Sun Xiangfu said it seemingly casually, but it was a flash in the eyes of many large grain households, taking wine as an example, just pointing out a direction for everyone, food, is not only this one use, processing it into a variety of delicious snacks and snacks, can also enhance its added value, however, at present, wine making is the most cost-effective, the entire northern and western regions of the market, need a very large amount of wine, it is a sharp weapon to deal with nomads or people in cold regions, on the battlefield, also need a lot of alcohol, This can only be achieved if there is an abundance of food production.

The chatter in front of the gate of the imperial city, after all, is short-lived, as soon as the gate opens, the courtiers rush in, and the people who really put what Sun Xiangfu just said in their hearts, after going back, should make adjustments to their own industries to avoid damage, which can be regarded as a good thing that Sun Xiangfu did indirectly!

After the meeting of the early dynasty began, there was not so much harmony between the ministers, first of all, Yu Shinan and Kong Yingda came out to talk about the issue of education, although now Yu Shinan and Kong Yingda are subordinate relations, but Kong Yingda did not give Yu Shinan face at all, and first opposed the matter of the imperial court using education for profit.

Secondly, he impeached the Yu family for profiting from the cultural industry, smearing the faces of the readers, and he advocated opening the Guozijian to foreign students for free to promote the culture of our Han family, and the state should prohibit the commercial behavior of profiting from classic articles, ink treasures and other things, he believes that these things are sacred, and they circulate in the hands of all kinds of small traders, which is undignified.

If such an impeachment had been taken out a few years ago, it might have been able to stand, but now, it has made most courtiers look sideways, because everyone has become accustomed to rational thinking, whether it is the education industry or the cultural industry, as long as it can bring benefits to the country, why not do it?

"That, Kong Sai Wine, although our Datang's economy has been improving in recent years, even our own students can't afford it! Why do you support expatriate students? ”

Sun Xiangfu's understatement question made Kong Yingda's face flush, opening a school and charging tuition, in fact, he can understand, but he can't understand that the tuition fee for a foreign student is set at 1,000 yuan a year, this is no longer the promotion of education, but commercial profit.

After a while, Kong Yingda, who had figured it out a bit, said, "The old man didn't say that it was completely free, just charge the cost appropriately, the price of 1,000 yuan per student per year is too high, which will make the monarchs of various countries think that my Datang is a mercenary country." ”

In a sense, what Kong Yingda said is also somewhat reasonable, but it is not right.

Sun Xiangfu continued to answer, "Kong Saijiu thinks that the knowledge that I teach to those students every year in Datang is not worth a thousand yuan? ”

Kong Yingda is not easy to answer, knowledge is priceless, after those foreign students who have learned knowledge in Datang return to China, it is impossible to calculate how much benefit they can generate by relying on this knowledge, invisibly, he was led by Sun Xiangfu to the idea of calculating the gains and losses of interests, these, Kong Yingda will be for a while, but he can't figure it out.

Sun Xiangfu didn't wait for his response, and continued, "The minister thinks that the knowledge of the Tang Dynasty is priceless, especially the Confucian classics, and those foreign students have paid high tuition fees, so we should teach them our most precious Confucian classics and make them worth the money." Since Kong Saijiu is so distressed about the wallets of those foreign students, he should spare no effort to teach these students, and the minister suggested that the imperial court should first open up the Confucian college to foreign students.

In addition, when it comes to education, a few days ago, the children of the Taiyuan Wang family had found a minister and wanted to fund the construction of an agricultural college for the imperial court in Shanyang. ”

To establish a college in Shanyang, if it is compared with the scale of the medical school, it will cost at least hundreds of thousands of yuan, and the Wang family donated it in vain, to say that there is nothing greasy in it, the ministers in the court do not believe it, this matter, Sun Xiangfu had mentioned it when he was chatting with Li Shimin before, there is a cheap white get, Li Shimin will naturally not let go, today, officially take it out for discussion, naturally it is to grade this Shanyang Agricultural College, go through the formal procedures, and return it to the imperial court.

"Your Majesty, the minister thinks that the Agricultural College should not be established in Shanyang, but in Chang'an."

When Li Shimin made eye contact with Wang Gui in the waiter, and was about to settle the matter, someone jumped out to speak, it was Yang Ji, a member of the ministry, who was a descendant of the Hongnong Yang family.

As soon as he said this, many Guanlong families also seconded the proposal, believing that education is the foundation of the country and should be placed in the capital to facilitate the control of the imperial court, and even, some people suggested that Shanyang Medical College should also be moved to Chang'an, and even Wei Zheng, Changsun Wuji, Fang Xuanling and other political allies of Sun Xiangfu also had the posture of seconding the proposal, but they knew that Sun Xiangfu might still have his own rhetoric, so they chose to see the situation first.

Now the early court is deliberating, that is, more than 100 officials, Sun Xiangfu has been in Chang'an for half a year, and most of them know about the names of these people, and most of these people who came out to stop them are people from the Guanlong group, and they don't want to put these things that represent the country's center of gravity in places other than Guanzhong.

Because, the more developed Guanzhong is, the more beneficial it is for them to be the head snake, like Sun Xiangfu to develop Weinan, it has been supported by them, as long as you do industry here, they will be able to benefit more or less, and concentrate the college in Chang'an, then Chang'an's population and business will inevitably be more developed, and the business of the Qinglou tavern shops they opened will be easier to do, but don't think that the ancients didn't understand the economy, even if they didn't understand, they have learned a lot in the operation of Sun Xiangfu's various business methods over the years, They have begun to have some business vision, which can be regarded as their growth!

Kong Yingda didn't know why the topic was turned to by them, and the question of where the Agricultural College should be built, it seemed that everyone chose to ignore the question he just asked, and the old man couldn't figure it out for a while, so he had to follow everyone to watch the play first.
