Datang Nongsheng

Chapter 721

Three rivers, namely Heilongjiang, Wusuli River, and Songhua River.

Surrounded by these three river systems, the Sanjiang Plain is covered with the most fertile black soil in my country, with a very high content of organic matter, which is perfect for farming.

In view of the long freezing period and the large temperature difference between morning and evening, Sun Xiangfu also needs to lead the children of the farm to develop crop varieties suitable for local cultivation. The Northeast rice of later generations is not the same as the Jiangnan rice.

Of course, it is not difficult to improve it. The late-planted rice varieties in Shannan Road can adapt to certain temperature changes. After arriving in Yanjin, Sun Xiangfu quickly planted a rice test field. Judging from the earing situation, the yield should not be low, as long as a little attention is paid to its cold storage characteristics, the impact on the yield of rice seeds will be fine.

After all, most of the time, areas with large temperature differences between morning and evening can have a positive effect on crop yields, because they can more effectively combine photosynthesis with plant self-repair, such as melons and fruits in Shanyang, wheat, The yield is higher than that in Guanzhong, and it is sweeter. This is not only because of the fertility of the land, but also because of the altitude and climate. When it comes to the place of origin in Xinjiang, the temperature difference between morning and evening is greater, and the ones planted will be more productive and more delicious. sweet.

Therefore, for thousands of years, it is generally believed that farmers do not need cultural knowledge, which is the biggest mistake. It is difficult for a person without knowledge to grow a good field. An agricultural expert, compared with an ordinary farmer's yield, and crop appearance, There is a huge difference, because experts who do research understand its various characteristics, while ordinary farmers mostly don't understand anything.

After Sun Xiangfu joined the work in later generations, he often encountered that the fruit trees planted by farmers did not bear fruit, or the fruit they produced was so sour that it was difficult to swallow, so he had to secretly beat cyclamate to take away, and the corn planted did not bear cobs, but the fruit produced The shortage of sticks and rice is very serious, the same planting method, the same crop, the yield is quite different, and so on.

They don't know the reason at all, and usually after causing losses, they seek advice from top agronomy students like Sun Xiangfu. After receiving scientific explanations and corrections, they realize that it is not that simple to grow any crop well. Rely on knowledge.

That's why some college students often return to their hometowns to farm on the Internet, with high yields and high incomes, and news about how much money they earn is published, because these college students have acquired knowledge and are sure to grow some crops well, so they choose to go back to farm.

The spring plowing around Yanjin City has grown very well after receiving comprehensive technical guidance from Sun Xiangfu and a group of agricultural students. , and after Sun Xiangfu's speech, it was easily completed.

With the support of the people, the efficiency of doing things is really high. After seeing the things that Chang'an transported, the kind that can absorb water from the river and spit it out after a rumbling roar, everyone almost regarded Sun Xiangfu as a god. Come on, this is too subversive of their cognition.

"It's not bad, the power is much higher than I imagined. After adding a turbo water pressure design at the bottom, the water can be lifted to a higher drop height. However, ten sets are still too few. It doesn't mean that the model machine in mid-April Was the experiment successful? Why did it take only three months to produce this amount?" Sun Xiangfu asked Liu Shili, the captain of the imperial army who brought the water pump over.

Liu Shili replied, "There are already quite a few. All academicians have their own research tasks. The design of these water pumps was only researched and modified by a few academicians in the original R&D team. It was finalized last month and started production. Yours Do you think it is convenient enough to use?"

He was originally a member of the secret guard, so Li Chengqian would entrust him with matters involving confidentiality. When he was in Weinan, he was responsible for leading the imperial army to protect the safety of all research fellows. Now, each of them is He was regarded as a treasure by Li Chengqian. Of course, the task of delivering the water pump was only on the surface.

As Liu Shili has been in the research institute for a long time, he also knows some of the pertinence of these research and development projects. Because the water pumps with low technical content are for civilian use, they are required to be easy to use. In this regard, several academicians can No less effort.

"It's already very good, but there is still room for improvement. After you go back, tell them that the fuel opening can be made bigger, so that more charcoal can be piled up and burned underneath, so that no one has to watch the fire all the time.

In addition, the entire chassis is covered with a large iron shell that is integrated to prevent dust and dirt from getting inside, affecting the service life and preventing its operating principle from being leaked.

For these few units, I will ask my subordinates to make a few wooden shells and pack them. You will ask them to make some iron shells and bring them back when you come next time. Wooden shells are used for a long time and have fire. danger. "When Sun Xiangfu said this, he pointed to the stove where the firewood was burning, and Liu Shili understood it.

After the brief trial was over, Liu Shili found a place where no one was around and said to Sun Xiangfu, "The research team has started the research project of 'electricity', and Academician Ma asked me to come over in person, just to ask Do you have any suggestions for the direction of this thing, you don’t need to tell me, after writing it, seal it with wax, and I will take it back with me and give it to them.”

Sun Xiangfu nodded when he heard the words. Although he is not a science student and has forgotten more than half of the science knowledge he learned in later schools, he still needs to know the main principles and some basic knowledge of common sense.

For example, tungsten filaments can be used as light bulbs, and copper wires must be wrapped in rubber for insulation. Everyone knows the knowledge.

When Liu Shili said this, Sun Xiangfu really remembered a lot of knowledge in these areas. Before that, Sun Xiangfu didn't include it when he was compiling the Jiuyuan County School and junior high school physics textbooks.

Because, at that time, there was no basis for getting electricity out, and it would be shocking for you to write down the principles and some applications of electricity. At that time, you just wrote down many physical laws and some calculation formulas that he still remembered, and handed them over to him. It is given to the students to research and verify, and now it is also applied to actual research.

Three days later, Liu Shili set off back to Weinan with all Sun Xiangfu still remembered about electricity and some forward-looking cognitions about the application of steam engines in vehicles, ships, textiles, etc.

And Sun Xiangfu also began to go to the Sanjiang Plain with the reclamation team organized by Su Dingfang and the others. It is now mid-July, and in the one or two months before the freezing period, they strive to complete the land reclamation, villages, and cities. Some of the planning tasks, as for the construction, the construction will basically start after the snow melts next year.

"Ah Lang Hehe~...
The Ussuri River is here, long and long~
The blue river water, with waves~
Mohe people let go, thousands of nets~
The river is full of boats, and the warehouse is full of fish
······"

Not everyone could understand what lyrics Yu Xiuer sang, but everyone who heard her singing, Mohe, or the people of Shiwei and other tribes, felt a crisp, sweet, and transparent feeling in their hearts. The inexplicable mood has improved a lot, and it is much easier to work.

In the past few days, they have seen the power of the Han people, the kind of large fishing nets with a length of [-] meters and a row of large stones at the bottom. They only need to choose a wide water area in the lake area and use a boat to set it down. Two groups of people pull it. Pull the two ends of the big pull rope to the shore, and the big fish in the lake who don’t know how many years have been grown are pulled to the shore in piles. The people only need to put the prepared big frame on the shore, Just pick a big one and put it in the box.

In just one day, with dozens of such large nets, pulling a few times each, they caught enough fish for people to eat for many days. After that, the Mohe people and Shiwei people who did not have much food left at home could feel at ease. followed them to work.

Set fire to the wasteland in designated areas, build dams, and set up water pumps. Those places that were originally full of reeds and pheasant nests, after being pulled by plows, turned into pieces of fertile fields. It is said that the grain grown every year in the future , everyone lay at home and ate all winter, and they couldn't finish it.

Moreover, a large part of them are not opening up wasteland, they are planning places according to the height of the terrain, some are opening caves, burning bricks and tiles, and some are planning village homesteads. It is said that next year, this place will become Wuli One village, one episode ten miles away, one county within one hundred miles.

All the houses are built with thick big bricks and strong and strong birch trees as beams. No matter how heavy the snow falls in winter, they cannot be overwhelmed. People can also burn kangs and kettles in the houses, even cattle and sheep. It is also living in such a warm house, so that everyone will spend the winter in the future, and they will no longer have to hide in caves.

The most important thing is that people like myself don’t need to pay anything to get these houses, fields and so on. They just need to follow those Han people who teach farming and learn how to farm, even if they haven’t seen the products in the fields yet. Out, or what those warm and comfortable houses are like, but they also feel that this is a hundred times better than when they surrendered to Goguryeo.

Because, since they surrendered to the Tang Dynasty, they have never paid taxes, and they often receive some finely crafted clothes from the general who ruled here, or strong wine and a certain amount of food that can keep the cold away. Basically, they will not be in danger of freezing to death during the winter.

Some people are sick, and there are medical officers in white clothes who give them pills, which are not bitter at all. After a few days, most of the diseases will be cured. As long as people don’t die in the winter in the tribe, the number of newborns will soon increase. The trend of population growth is also very fast.

In the past eight or nine years, they have fully understood what is meant by the Kingdom of Heaven, what is the bearing of the strongest empire in the world, and what a wise decision their leader made when he chose to surrender to the Tang Dynasty.

It’s dark, the bonfire is lit, and the delicious food can be eaten open again. There is also the kind of strong wine that will warm the whole body after a sip. Everyone can drink a bowl every day, and then everyone can gather around The bonfire sang and danced, and those Han musical instruments could make the most beautiful sounds in the world to accompany everyone. There is no happier life than this.

Emotional exchanges are just like this. The army of the Tang Dynasty fought together with soldiers from Shiwei, Mohe, Qi, Khitan and other ministries, so they established friendship.

Now, the people of these tribes, together with the people and officials of the Tang Dynasty, have fished, opened up wasteland, planted land, built villages and cities together, so they have also established friendship.

Just a few days of living together gave them a certain amount of friendship with each other, and with the subsequent entry of more tools and materials, and a longer period of working, living, singing and dancing together, the friendship between tribes and ethnic groups The estrangement will become less and less, laying a solid foundation for a long-term settlement together in the future.
