Datang Nongsheng

Chapter 734
If possible, who wouldn't want their offspring to advance to a higher civilized class!However, Lu Dongzan looked at the vast snow-capped mountains, after all, he did not have any confidence in what Sun Xiangfu said.

There is no other reason. There are too many barren lands in Tubo. Under such a vast glacier, it is impossible to be self-sufficient except relying on external supplies. With the planting technology of Tang Dynasty and high-yield crops, at best, it can only alleviate it. .

Because, no matter how good the crop species are, you may be killed by hailstones of unknown size after a cloud flies by.

If the Tang court wants to ensure the livelihood of everyone here, it needs to keep giving money to this place, because the population is bound to grow and develop, but if Datang itself can continue to be so strong forever, is it still willing to give money to this place? ?
He is not a person who does not understand the history of the Central Plains, especially in the past two to three hundred years, the regime of the Central Plains has changed very frequently. It can be said that it is not as stable as their Tubo. Ren Zanpu has been around for hundreds of years without any subversive changes.

Seeing Lu Dongzan's impossible expression, Sun Xiangfu said again, "I know you still have doubts in your heart, but I will use the facts to dispel your doubts."

Lu Dongzan asked, "What are you going to do?"

Sun Xiangfu smiled and said, "It depends on what you lack in Tubo. If you lack anything, I will let you produce something here. Isn't the problem solved?"

Lu Dongzan said smoothly, "We are short of food, wood, fuel, fodder for livestock, salt and iron, and clothing..."

After he finished a series of things, Sun Xiangfu smiled and said, "Actually, you didn't lack anything here, but because you only know how to cut down and consume, but don't know how to plant, you have no shortage of everything here.

Hundreds, thousands of years ago, these low valleys should have been covered with shrubs and even trees!But why is it gone now?It is your survival mode that has pushed yourself to a dead end. "

To say that all of Tubo is located at an altitude of more than 6000 meters like Tanggula Mountain, that is not necessarily the case. The places below 3000 meters above sea level account for at least half, and the places below 3000 meters account for [-] to [-] percent. At many altitudes At places below [-] meters, there are at least seven or eight months of the year without snow, and the temperature is even comparable to that in the Central Plains. All kinds of trees and shrubs that can be planted and grown in the Central Plains can grow here. to great.

Moreover, trees can also be planted at an altitude of 3000 meters to more than 4000 meters. Such a place also does not freeze all year round. There are several months in summer, and there is snow water that melts on the top of the mountain, constantly nourishing Let the water and grass grow here to feed their cattle and sheep.

In places where even aquatic plants can grow, let alone trees, Siberia is covered with ice and snow all year round, and there are still large tracts of primeval forest. keep warm.

As far as Sun Xiangfu knows, there are many trees suitable for growing in such plateau areas, such as cold sweater, spruce, alpine oak, alpine pine, ginkgo, white birch, camphor, etc. There are more trees, some It can even produce a lot of economic value, such as camellia trees, alpine rhododendrons, etc.

Of course, if these things really want to grow here and change the environment here, at least like Shanyang, they have invested a lot of manpower to plant them for more than ten years, and even need one or two generations of growth. , to see some results.

However, Sun Xiangfu still has a magic formula. If it is just some food, clothing and other condolences, with the current abundance of materials and the development of industry in Datang, he can't afford to spend two or three months to prepare.

Among the things he brought over, there are [-] sets of solar pots, cooking pots and stoves.In the future, another [-] sets will be delivered every three months.

Don't underestimate these things. With it, a family doesn't need to light a fire to cook or boil water for almost half of the year.

Because, regardless of the cold weather on the plateau, there is plenty of light, especially in several low-lying habitats. There are very few continuous heavy rain seasons, which can be seen from their red skin sunburned by ultraviolet rays. see.

Therefore, even in the era of advanced technology and sufficient supply of coal and gas in later generations, local people still use this kind of solar pot to boil water and cook rice in large quantities, which is very energy-saving and environmentally friendly.

As long as this kind of pots and stoves are popularized in all Tibetan households in the future, they can save at least [-] to [-] percent of the fuel used for cooking meat and boiling water in the past.

In addition, Sun Xiangfu brought enough seeds to plant 10,000+ acres of corn, sweet potatoes, potatoes, soybeans, cotton and other crops.

Not only are they high-yield, but they are also better than barley, wheat and other crops currently planted in Tubo, like corn, cotton, and platycodon grandiflorum from soybeans. They are also good fuels for firewood.

Anyway, after a certain amount of relocation, there will be no more than 20 households in Tubo. Using solar cookers and these bellflower fuels can basically supply more than [-]% to [-]% of their fuel. At least, there is no need By cutting down trees and digging the root system of shrubs to keep warm, even a lot of manure from cattle and sheep can be saved, which can be used to fertilize and fertilize the fields.

Then, while there is no need to cut down trees, if a certain number of trees are planted every year, there will be more and more forests here. After a few decades, the firewood cut down by pruning alone will be enough for many people to keep warm Of course, at that time, it may not be necessary to rely on firewood for heating, because the times may have advanced to the point where coal mines or natural gas can be used as fuel.

It can be said that as long as the Tibetans' planting problems are solved now, their fundamental problems will be solved, and the ecological balance will be adjusted by scientific means. Not to mention the Tibetans in this period, even the Han people cannot imagine That is to say, Sun Xiangfu, a time traveler, always thinks about problems from the side of the scientific view. Therefore, when the problem comes to him, it will become very simple and have a direction.

Just relying on talking, Lu Dongzan couldn't understand how people can change the world, so Sun Xiangfu didn't bother to explain to him, just let him watch what he did.

After some busy work, the large team of 4 to [-] people finally settled down.

In Sun Xiangfu's greenhouse, the pressure cooker was bursting with heat. After Sun Xiangfu received Li Shimin's imperial decree, he sent a letter to Marseilles to make it specially. Otherwise, they would have to eat half-cooked food like the Tubo people. It's a pity that time is limited, and I can't build more, only a dozen.

Therefore, these pressure cookers are estimated to be used for several rounds, specially for the female members with severe altitude sickness, to cook some easy-to-digest nourishing soups, and the male members are not balanced, so they have to endure it. Enjoy!

There is a pot of chicken stewed with Hericium erinaceus soup, and a few slices of wild ginseng are put in it. Even if you can't eat anything, drinking a bowl of this stuff will provide enough calories for your body.

After they were full, Sun Xiangfu took a rest early. As long as they didn't go to places above 500 meters above sea level, their headaches would become less and less severe until they felt nothing at all.

At dawn the next day, Yu Xiu'er, who got up earlier, was in a much better mental state, but she suspected that the watch on her wrist was broken, and she was looking for Li Xiangdie and Yao Hongxiu to set the time.

Because it was just dawn tomorrow, but the hands on her watch showed that it was almost nine o'clock in the morning. What made her even more strange was that the watches of Li Xiangdie and Yao Hongxiu were also like this, so Sun Xiangfu was pulled over by her. Woke up while looking at the watch on the wrist.

"Don't look, the watch is not broken. It's where we are. The time zone is different. It's usually dawn at around nine o'clock here. In summer, it doesn't even get dark until ninety o'clock in the evening. It's different from Shannan Road. "Sun Xiangfu withdrew his wrist and said.

Yu Xiuer asked in confusion, "What is a time zone?"

While putting on his clothes, Sun Xiangfu said, "This is where we need to talk about some astronomical knowledge. The world we live in is spherical. Daoist Li has already proved this. Then, the reason why the sun rises and sets is because This spherical world of ours is rotating, and one revolution is a day, and as it rotates, there must be places that are illuminated by the sun first, and places that are illuminated by the sun afterwards.

Here, the sun shines later than Shannan Road, while in Liaodong and Wazhou, the sun shines earlier than Shannan Road. Therefore, I also wear a watch. When in Liaodong, when it is dawn , you will find that it is only past five o'clock, but in the Tubo Plateau, it is past eight o'clock. In summer, when the day is long and the night is short, it is more obvious..."

The existence of a watch can prove the rotation of the earth. Sun Xiangfu once wrote to the Anxi Metropolitan Guard to explain this problem to the ministers who thought their watch was broken. Now, it can be regarded as letting his wife feel the meaning of this world magic.

However, it is impossible for Yu Xiuer to understand the truth that human beings are actually sitting on the ground and flying at a speed of over ten thousand miles per minute, because Sun Xiangfu later said that the world revolves around the sun, and the sun is It is revolving around the Milky Way at a speed of more than 200 kilometers per second.

As for why you need to use a pressure cooker to cook, the chef who got up to cook this morning understood it.

If it is an ordinary pot to cook rice, it must take a long time and add a lot of water to cook it into porridge.

Otherwise, according to the cooking method in the Central Plains, the rice core will be hard. At this altitude of 5000 meters, the boiling point of water is only over 80 degrees. The people here don't have the habit of eating well-cooked food.

This kind of knowledge is simply miraculous for those who do not understand it. Those who understand it will think of ways to restrain it. The temperature of the steam is relatively high. Therefore, the staple food of the Xuanfu team this morning is steamed buns ,steamed stuffed bun.

Sun Xiangfu's breakfast is noodles pressed in a pressure cooker, mixed with some sesame oil, and served with his homemade chili sauce. A man and three women ate it so that their noses were sweating. Chili can forcibly open up people's sense of taste.

Now, Sun Xiangfu is no longer the only one who enjoys this. Yu Xiu'er and the others usually eat some. After their bodies relax a little, they have to have some food in their stomachs, so that they feel alive.

When the white snow on the top of the cliff in the distance under the strong light was shining brightly, the two or three thousand people of Subiru around Nagqu City were brought to the open space in front of Sun Xiangfu's residence. Most of them were wearing oil shells. Clothes like clothes, the body smells heavier than cattle and sheep, and the skin is black and red. Even a young man in his twenties looks older than a 34-year-old middle-aged man in the Central Plains.

The art troupe has a stage that can be quickly spliced ​​and built. After unloading the wood from the bullock cart, a wooden platform that is more than one meter high and three to four square meters is erected soon.

After Sun Xiangfu stepped onto the stage in ceremonial attire, he originally wanted to recite according to Li Shimin's edict, just like when Lawyer Pei and Zhang Yong went to Xingfu Village.

But after thinking about it, among these people, there are not many people who can understand the vernacular Chinese, so why do you still read it, but pretended to open the imperial decree and said, "His Majesty the Emperor of the Tang Dynasty said , under the rule of the Tang Dynasty, no poor people like you are allowed."

Then, he received the imperial decree and said, "So, congratulations, you will become rich soon."
