During this period, the black soil in Northeast China can be described as quite fertile, not worse than the Hetao area, or the lake area of Shannan Province, and the water system is also quite developed, especially in the Sanjiang Plain area, which is not only suitable for planting dry field crops such as potatoes and corn, but also can be developed and planted in large areas, and because of the fertile land, if only one season is planted a year, it is not much difficult to achieve high yield.

It's a pity that all the people living in this area are ethnic minority people who don't know how to farm, otherwise, they would have been able to get rid of the era of Ru Mao drinking blood and achieve prosperity.

In the early days of the founding of the People's Republic of China, the famous Hubei writer Nie Hongxuan wrote in "Song of the Great Northern Wilderness": The Great Northern Wilderness, the sky is vast, the land is vast, and there is a pond of withered grass and withered reeds.

The reeds are green, the reeds are yellow, the living die, the dead rot, and the soil is fertilized, and food is made for the next generation.

······

It can be said that the scene of this land is exhausted, Sun Xiangfu went to Liaodong, not only to promote new crops, but also to lead the local people in relatively remote areas to develop a part of this area, as long as there are three or five million acres, the food demand of the entire Dongyi Duhufu and Heishui Duhufu will basically be stable, if more, it will be economic income.

Let some of them settle down, get rid of fishing and hunting, and achieve prosperity, and soon, more people will understand how to make their lives more stable, safe, and prosperous.

After all, fishing and hunting are more dangerous, require a certain amount of luck, and can only barely maintain their survival, and cannot achieve prosperity.

The people in the Central Plains also entered the agrarian society, and gradually settled down and became rich, and then they had more time and energy to think about the philosophy of life and produce a more advanced civilization.

In addition, the breeding industry in the Northeast is actually very interesting, such as mink, deer, there is a very high economic value, even if it is woolen clothing, cotton clothing in the Tang Dynasty is prevalent now, the value of a mink is also very expensive, especially the whole skin that is not damaged at all, in the Chang'an market, ten runs and eight times can not be bought.

A family of ordinary people does not need to raise more, only need to raise a dozen, even if the price of selling to traders will be lower, they can earn more than dozens of times a year, which is much higher than the income of many people who farm land in the Central Plains.

Not to mention the deer whose whole body can be used for medicine, people like Sun Xiangfu often miss deer antlers, deer whips, such tonics, who calls the family too many women, and needs to work hard night and night!

Now, the rich group of Datang, but in the day by day, this kind of nourishing things, the market will naturally get bigger and bigger, in the future, relying on the wild market alone, it must be difficult to meet, the price is inevitable, and if you want to meet the market, you have to develop artificial breeding.

In these aspects, Sun Xiangfu can start with the official first, do some basic breeding research, and then gradually teach the local people.

Thanks to the technical support of hundreds of agricultural students sent to Liaodong before, many people here have mastered a relatively scientific way of preparing fields.

Crops such as corn, potatoes, sweet potatoes, peanuts, and peppers are not difficult to plant.

In the middle of April, all kinds of seedlings have begun to sprout and grow, and the people have more time to listen to Sun Xiangfu and the peasant students in addition to irrigation, because when they give lectures, all of them are in Chinese, and the Chinese level of the ethnic minorities in Liaodong who rushed to listen to the lectures has improved a lot, of course, this also has the credit of Yu Xiu'er and her daughters who frequently perform songs and dances in various ethnic minority tribes with the members of the Andong Army Art Troupe.

Su Dingfang, Shangguanyi, Cheng Mingzhen, and Zhang Jian have been communicating with various departments with a certain level of Chinese, as well as some people who have a considerable level of cultivation, and are doing mobilization work.

Different from the national education in Liaodong, the people in Guanzhong, who are already relatively wealthy, are more concerned about entertainment and play.

Because, waiting for the days of summer grain harvest, they are actually more leisurely.

After all, now the imperial court no longer requires them to plant as much land as they want, and those who work can not plant a single acre of land, those who have more labor at home can plant a few acres, and those with less labor can plant a few acres less.

The people of Guanzhong, who already have the level of intensive cultivation, do not need to often listen to the folk studies lectures taught by the agricultural officials, and only when the new crops are promoted, they need to study intensively.

Therefore, the opening ceremony of the Tang Imperial Zoo presided over by Li Chengqian was very lively, and the opening ceremony of the Imperial City Park and the opening ceremony of the Royal Museum were the same, and were sought after by all the people concerned.

Empress Changsun, who attended the opening ceremony at the gate of the zoo, has been complaining that the ticket price is set too low, only two pennies a piece, otherwise, so many people don't know how much money they want to make.

Li Chengqian had to comfort her and said, "Queen Mother, our Datang has enough money, not bad, let the people see more strange affairs, increase their knowledge, in fact, it is also beneficial, understand the habits of poisonous snakes and beasts, when he encounters accidents, he can better survive and avoid harm."

Proper handling of some small creatures can also allow them to avoid causing damage and even discover some ways to get rich.

Let's talk about the several poisonous spiders in the Spider Museum, before, when everyone was unconscious, I don't know how many people got sick or died, maybe we had these things in the palace before.

Now, everyone knows how dangerous it is, and once it is found at home, it will be cleaned up to prevent it from harming people and making everyone's life safer.

There is also the kind of rat with sharp mouth, gnawing poisonous teeth, plague, which is caused by this kind of rat, before, some people's food was eaten by these rats, but they were reluctant to throw it away, and finally ate the disease, and even infectious diseases, which harmed many people.

Now, after listening to the explanations of the narrator, after recognizing this kind of rat, when you see it again in the future, you will find a way to kill it, and even the nest will be eliminated, and the food that has been eaten by the rats will never be eaten again.

Only by improving the knowledge of these aspects can we make the lives of the people of Datang safer, and the population can maintain stability and rapid growth. ”

Empress Eldest Sun listened to what Li Chengqian said, and her heart suddenly felt better, and she pointed to the museum opposite the zoo, which was renovated from the original royal inner treasury complex, "In this museum, there are the most valuable treasures of our royal family, why do you also set such a low ticket price?" We don't play it ourselves, but we open it to all the people to play, this shouldn't be for the sake of the people! ”

All right! A man who has been an iron rooster for most of his life, you expect him to be generous all of a sudden, it is impossible, Li Chengqian had no choice but to explain again, "Queen Mother, in this museum, there are not only our royal treasures, but also all kinds of objects that can be collected now, since the pre-Qin period.

For example, there are dozens of kinds of cars, maybe you don't have any feelings about it after seeing it, but a craftsman, if he sees the most advanced car in Datang from the most primitive car, he may have many feelings, and some good inspiration may be able to prompt them to transform the car more advanced.

Others such as tables, chairs, benches, and even the clothes we wear, are the same, ten years ago, the clothes we wore were not as fine, comfortable, and convenient as they are now.

In this way, some comparative displays can make the people feel the importance of the progress of scientific and technological civilization and know what aspects to start with.

Of course, putting these aside, these things used to be placed in the palace, and they needed a large number of eunuchs to take care of, raise so many people, maintain them every year, and spend a lot of money on all aspects.

Now, it is publicly displayed to the public, which not only reflects the enlightened generosity of our royal family, but also offsets these maintenance costs through tickets, and even achieves a small surplus. ”

Empress Eldest Sun is not really stingy, she just wants to make more money when she has money, and likes to let those who can pay for it pay more money for herself, although she is used to being diligent and thrifty, but when she really wants to spend money to support Li Shimin's career, she is not stingy at all, for example, the reward items used by Li Shimin to buy people's hearts during this time are as high as millions of yuan, which she waved her sleeves to purchase.

Of course, when she gave this money, she was a little nostalgic for the time when she encountered such a thing before, and there was a scene where people like Sun Xiangfu could exploit it, but she didn't think that her man had robbed all the other people's properties, and she didn't know how much she had earned in the past few years.

Now Li Shimin is in the capital of Anxi, and he has met the people, whether it is the people with household registration in the Tang Dynasty, or the laborers from the countries of the Western Regions, he first smashed a few gift bags with rich contents, why are people dizzy, such a stupid and rich emperor, who else can say that he is not good?

Therefore, a woman like her is actually a model of virtuous help, she understands things, and after hearing Li Chengqian's explanation, she is not entangled at all, and even, she is afraid that Li Chengqian will not understand the truth, and deliberately quotes Li Chengqian to say, who knows that when this guy talks, it is a routine to talk to Sun Zhengming, and it is no wonder that these two people always have endless letters all year round.

"His Royal Highness the Prince, there is news from Weinan that the working model of the steam engine has been made, and Ma Sai, Zheng Mingli, Song Xiaoyu and others from the R&D team invite you to Weinan to witness its practical application test." After Li Junxian, the deputy commander of the forbidden army, received the report from his subordinates, he walked quickly to Li Chengqian's side and reported.

"yes, that's great."

Li Chengqian was overjoyed when he heard this, and was about to leave, only then did he remember that the queen mother was still here, and said, "Otherwise, the queen mother will also go with her sons to have a look!" Feel the power of science and technology. ”

Hearing Li Chengqian say this, the eldest grandson Wuji became interested, nodded and said, "There is nothing to do left and right, let's go and see this palace too!" ”

She had heard Li Shimin talk about this so-called steam engine plan earlier, and she didn't expect that in only about half a year, the working model had already been figured out, and she naturally wanted to see the magic of this thing that Sun Zhengming said was the most important thing for the future development of Datang.

After helping Empress Changsun to walk for a while, Li Chengqian remembered that there must be some reason why the people in the research group came to watch by themselves, and explained to Li Junxian, "Since they invited Gu to be there, there must be something that needs Gu's direct order, you quickly transfer 5,000 forbidden troops and go to Weinan with Gu." ”

"No." Li Junxian took the order and left, and in less than half an hour, thousands of people took more than ten large ships and headed for Weinan.
