Great time travel

Chapter 47. Construction is more meaningful than destruction

The bitter cold wind howling from the extreme northern ice sheet gradually slowed down as time went by.

And the sun seems to be stretching after a winter nap.

Gradually, Mother Earth also woke up from a sound sleep, opened her sleepy eyes, and began to take care of her back garden that had been abandoned for a season.The grass and leaves all over the ground are no longer the withered yellow of autumn, and the wind and frost of a winter have faded all their colors and returned to the soil.When spring comes, new grass leaves sprout its shy greenness.

In the warm spring breeze, birds with loud voices sing happily and fly among the blue sky and white clouds. Thousands of little lives are stretching their waists triumphantly, stretching their bodies after resting for a winter. , Impatient, they have poked their heads out early, laughing at the cold wind and ice and snow outside that although they are still baring their teeth and claws, they have already been strong and dry.The animals waking up from hibernation endure the scorching hunger in their stomachs, and can't wait to run from their hiding places to the vast natural world, greedily plundering all the food that can fill their shriveled stomachs.

The north wind and blizzard that have always dominated the prairie began to retreat. The rivers and lakes were gradually unsealed one by one. The accumulated frost and snow slowly melted. Like a small rushing waterfall, rushing and flying down to the depression at the foot of the mountain.

On the jagged thatched roofs in Ketun City, there are still some unmelted spring snow on many of them.The re-thawed and rushing Tula River has sprouted green willow buds, and the vegetation has turned green.A few swallows flew in and out under the eaves, holding spring mud in their mouths to repair their house that was destroyed by the wind and snow.

A group of knights swung their whips and drove their horses, carefully avoiding puddles on the road, and slowly walked out of the south gate of Ketun City.

——The road after the snow melted was muddy and wet, and the rammed earth was softened by the melted snow water, which made it easy to sink in many places.The puddles accumulated on the road are like traps, some are deep and some are shallow, the shallow ones do not reach the instep, and the deep ones can even bury people in them!
However, once he left the city gate, the surrounding scenery suddenly became clear.Looking around, the spring sunshine gently soothes the earth that has been tortured by the cold winter. Everything is gradually recovering from the cold and lonely sleep. On the dark black land after the ice and snow melt, tender green sprouts stand tenaciously in the slight cold In the morning breeze, the earth is covered with a thick green carpet... But this is not the pasture or weeds that nomads are used to, but the 22nd century high-tech crops that Doraemon sowed not long ago: 【Seven-day fast-growing wheat】and 【Edelweiss alfalfa】.

"...This wheat...is it true that it can be harvested after only seven days of planting? And it can grow in the early spring when the snow has not yet melted?"

Looking at the bunches of heavy grain ears and the farmers who are working hard in the wheat fields, Yelu Dashi feels that his world view will be subverted, "...Even if the yield per mu is only a few buckets, but how many crops can be sown in a year? Ten times—this output has far exceeded that of the fertile soil in the south of the Yangtze River!"

——In fact, before the Yuan Dynasty, under the influence of the civilization of the Central Plains, a small amount of agricultural production had always been distributed on the Mobei grassland.However, due to the extremely cold climate of the Mobei grassland, the lack of precipitation, and the poor cold and drought tolerance of early crops, it is always intermittent.After the rise of Mongolia and the conquest of iron cavalry, the grassland nomads gained an absolute psychological advantage over the farming peoples. They began to despise agriculture and admire nomadism, which made the nomadic economy unify the northern part of the Great Wall. The agricultural foundation left in the early days was eventually completely abandoned by the Mongols. , It was not recovered slightly until the Qing Dynasty.

Closer to home, on both sides of the river near Ketun City, the Khitan people originally reclaimed a small amount of farmland, and drove the Han people in the city to plant some cold-resistant grains such as barley and rye. However, the management was extensive and the yield was pitifully low. Being able to harvest 25kg is better than nothing.Most of the grains they usually eat can still only be obtained from the Han land in the south by trade, and they have been peeled off by those unscrupulous profiteers.

But after switching to this [Seven-Day Fast-Growing Wheat]... the city of Ketun can already get rich by exporting grain, okay? ! !
Moreover, if this [seven-day fast-growing wheat] can be promoted in the entire Mobei grassland, turning the entire grassland into the south of the Yangtze River...then those who can come up with this kind of fetish will definitely become the leader of the entire grassland in one fell swoop. The food and clothing parents of millions of nomads, and the living Buddha of thousands of families, are worshiped by every nomad with extreme piety. Every sentence is worth [-] sentences on the grassland, which is more effective than any hero or khan!

Because the hero's sword will only expropriate cattle and sheep from them, but this magical crop can keep them from starving forever!
Thinking of this, he couldn't help becoming more and more afraid of Guo Jing, the "immortal" of the Song Dynasty, but he had some terrible thoughts from the bottom of his heart...

※※※※※※※※※※※※※※※※※※※※※※

Compared with the horror, shock and fear of Yelu Dashi, the travelers expressed their calmness: in Doraemon's pocket, there are so many incredible things that cannot be counted.Wheat that can be harvested within seven days of sowing is nothing. Doraemon also has a kind of [indoor rice] that can be planted directly on tatami mats, and can be harvested within half a day after sowing. A paddy field in one room can produce thousands of rice cakes!

Therefore, while watching the horses nibbling on the fresh, juicy and nutritious [Edelweiss alfalfa], Wang Qiu leisurely hummed an old song that fits the environment: "...The boundless world is mine Love, the flowers are blooming at the foot of the rolling green hills..."

At the same time, Doraemon is proudly showing off the achievements of biotechnology in the 21nd century to the bumpkins of the 22st century.

"...This [seven-day fast-growing wheat] is a cold-resistant, drought-resistant, barren-resistant super crop jointly researched by scientists from various countries through genetic engineering in the early days of the development of the Antarctic continent in the future world. It can adapt to various harsh climates, especially cold-resistant and drought-resistant. , claiming that it can grow on icebergs!"

Doraemon held up a bunch of ears of wheat, and introduced to Guo Jing and Nobi Nobita, "...In addition, it has another advantage, that is, it is easy to cultivate and does not require intensive cultivation. As for the disadvantage, it is that every round The yield is relatively low, and it is not resistant to heat and waterlogging, and it will lose its harvest after being flooded. Moreover, it has poor resistance to diseases and insect pests, so it can only be planted in cold and dry places, which is just suitable for the Mongolian grassland..."

However, no matter how powerful this [seven-day fast-growing wheat] is, if it is planted on a large area on the Mongolian Plateau, problems will still arise.

To be honest, the Mongolian grasslands are actually not very suitable for the growth of crops.From ancient times to the present, why has the economy of the northern nomadic peoples been less developed than that of the Central Plains?Why do these nomads keep going south to invade the Central Plains?Because their natural environment is too barren and fragile, it is only suitable for extensive nomadic farming - there are too few rivers on the grasslands, the average annual precipitation is only [-] millimeters (about [-] millimeters in the Jiangnan area), and water resources are not very sufficient , and is close to the desert, it is easy to be attacked by the desert, and the phenomenon of sandstorm is even more prominent.Under such relatively harsh natural conditions, the vast grassland is a natural fortress against deserts. It can prevent soil erosion and sand movement, but most crops that need to be harvested regularly cannot.If the grasslands are forcibly reclaimed on a large scale and crops are replanted when the technical conditions are insufficient, the desertification of the Mongolian grasslands will be accelerated in a very short period of time, causing unprecedented damage to the ecological environment of the entire northern China.

In the late Qing Dynasty and the period of the Republic of China, China once reclaimed the Mongolian grassland, which was still in the relatively humid Monan grassland, but the result was still much less than the loss—after the grassland was reclaimed and destroyed, the soil erosion was very serious, and the soil nutrients quickly It will be lost, and the cultivated land obtained will be abandoned within a few years, which will lead to desertification of the land, frequent sandstorms, and finally make the streets of Beijing and Taiyuan scrape sand all day long.

Therefore, after the founding of New China, the desert in Beijing has invaded to a position less than 20 kilometers away from Tiananmen Square. The country has to spend huge sums of money every year to build shelter forests, prevent and control sand, and pay for the indiscriminate reclamation that year... This is really A sad story...

In view of the above-mentioned painful lessons, as a cat-shaped robot with high integrity, Doraemon has already thought of this trouble for the Khitan people, and has prepared a solution-that is another pioneer of polar development in the future world. : [Edelweiss alfalfa]!
As we all know, alfalfa, which is native to West Asia and Europe, is the king of forage grass. It is this kind of excellent forage grass that is resistant to barrenness that allowed Europeans to maintain a large number of cavalry troops in the Middle Ages, instead of being like the Chinese in the Song Dynasty. It is because of the lack of horses... The [Edelweiss alfalfa] developed by Doraemon in the 22nd World can even grow in barren places like the Antarctic continent for livestock to eat.

With the help of this thing, as long as the Mobei nomads in Kedun City don't abuse the land, after planting several rounds of [[-]-day fast-growing wheat] in early spring every year, they will replant the cold-resistant [Edelweiss alfalfa] ], you can rely on this excellent pasture grass with nitrogen-fixing ability to provide a large amount of organic matter for the soil and restore the fertility of the land.At the same time, it can keep the land covered with vegetation to avoid soil erosion and desertification.

At this moment, under the deliberate adjustment of Doraemon through the [Weather Controller], the newly reclaimed wheat fields around Ketun City are in good weather, and the growth of both wheat and alfalfa is in the best condition.Simple metal farm tools such as hoes, sickles, etc. are also available from Doraemon - just find a few samples and put them in front of the [replica mirror] to take a picture - the only trouble is that any crop is Those who need to work hard, but Mobei lacks agricultural traditions. There are many good shepherds and milkers, but it is difficult to find good ones who grow crops.

Fortunately, there are many Han people, Xi people and Bohai people living in the city of Ketun. They were also cultivating the rye and barley outside the city before, and they knew a little bit of farming skills—even though the land they planted was very poor. It's not flattering, just like Noda, he almost never fertilizes, waters, and doesn't bother with pest control.But at any rate, it is still at the level of agricultural peoples, much stronger than traditional nomadic peoples such as Mongolians, Turks and Khitans.

In short, the "large-scale production movement" in Ketun City in the spring of 1127 AD was basically successful, and the harvest was also considerable.

More importantly, the travelers have changed the economic and social forms of this grassland without knowing it...
