Fortunately, there is no endless road. Pen "Fun" Pavilion www.biquge.info

There is an unexpected joy, that is, the prince issued such a warrant: the first batch of immigrants to come to the place of residence is not imposed, and they can choose freely within a certain range.

This certain range refers to being within a radius of 100 miles to the eastern part of the Loess Plateau, that is, close to this side of the plain. Moreover, the first immigrants could get as much land as they could. No taxes for five years!

What a blessing in disguise!

The hearts of the people who had been anxious and uneasy finally felt a little better.

According to the introduction of the people in the guard, under Yun Lan's proposal, everyone unanimously agreed to choose a place not too far from the guardhouse and settle down here. It is indeed not far from the guard, and it can almost be said that it is far away. However, it took three full hours to reach the destination.

Surrounded by mountains, there is only a winding path trodden by medicine pickers leading to the outside world, and in the past, except for the people who collected medicine, cut wood and herded sheep, and the people who surveyed the terrain of the Jin Palace, this place seems to have never been cultivated by humans!

Well, she can conclude that there has been no trace of human life here for at least the last hundred years. Because, it is too desolate, full of the rich smell of wilderness.

Yun Lan took the villagers and settled down in the wilderness.

The old patriarch was very alarmed: "On the first day of junior high school, there are not even a few big trees here, how can you build a house?" I haven't seen many stones, there is loess everywhere, what should I do with the foundation? ”

The second uncle was also panicked: "That's right, the first year of junior high school, although there are no tigers and lions in this place, I heard that there are still wolves!" The house must be built strongly, and thatched houses cannot be lived in for a long time! ”

"Huh? There are wolves? I'm so scared! Then the child burst into tears, trembling with fright, and went straight into his mother's arms.

"What should I do?" Tan Fuzi is a literati, a delicate wife with ten fingers around him who does not touch the spring water, and a pair of young children, and the fear in his heart suddenly swept like a frenzy.

The Loess Plateau is so desolate and backward, that is what he never imagined. At this moment, it would be a lie to say that he has no regrets in his heart. If it weren't for Chong Yunlan, this place, he would definitely not choose to come!

Yun Lan hurriedly comforted: "Don't worry, this place is the most suitable place to build a cave, it doesn't matter if there is no wood!" ”

Tan Fuzi's eyes widened: "Cave? What kind of house is this? Why haven't I heard of it? ”

It is not modest to say that he is well-informed, and he has read not a hundred geography books, but sixty or seventy. It can be said that he still knows the customs of various places very well. Caves? Well, I really haven't heard of it!

"yes, what the hell is a cave like?"

Everyone looked at her with burning eyes, a look of curiosity.

"Cave, I figured it out on the road." Yun Lan pointed casually, "You see, this loess has a vertical height of twenty or thirty meters, is extremely difficult to seep water, and has strong uprightness, which is very suitable for building a cave and this kind of residence. The climate is dry and rainy, with cold winters and scarce wood. Judging from our current situation, there is no other way but to build a cave. Even building a thatched hut without wood is not enough! Moreover, the cave can be fireproof and noise-proof, warm in winter and cool in summer.

It not only saves land, but also saves economy and labor, which is really a perfect architectural form according to local conditions.

Everyone is still ignorant.

Yun Lan sighed, immediately led everyone, chose a sunny mountain, leaning against the mountain, facing the open land, a solid hillside, and then squatted on the ground, with tree branches to draw a cave design drawing, and strive to achieve the perfect combination of ancient and modern, to create a real warm winter and cool summer residence.

"Well, that's good, it's yours, build a cave!"

After reading the drawings and listening to Yun Lan's story, the old patriarch muttered a few words to the second uncle, and then the final word was made.

Yun Maolin, the eldest grandson of the second uncle, soon gathered more than 20 young adults, and under the guidance of Yun Lan, everyone pondered together for a while, and figured out how to do it, so he picked up the hoe and shovel and pickaxe, and started to do it in full swing.

The first is to dig the foundation: after the orientation of the cave is determined, the foundation is dug. After the general shape of the foundation is dug, the surface must be repaired and leveled, which is called "scraping the cliff face" by the locals. Next, it's time to dig the cave. Dig out the shape of the cave and carry the earth away. After the kiln is laid, it is followed by the kiln, or called "cutting kiln" and "milling kiln". Starting from the top of the kiln, the arch is removed, and the kiln gang is scraped and smoothed. After the cave is dried, the loess and crushed wheat straw and mud are used for the mud kiln. The mud kiln has at least two layers of mud, one layer of coarse mud and one layer of fine mud.

Finally, it is to tie gables and install doors and windows. After the kiln mud is finished, the gables are tied, the doors and windows are installed, the high windows are installed on the doors, and the doors are placed in parallel with the low windows, one door and two windows. The door is against the window pan kang, and the chimney is set up against the wall outside the door, and the kang is against the window for the smoke to come out quickly, which is conducive to the cave environment and is good for the body.

The location chosen is very good, the front is dug with five holes, and the left and right sides are all based on the terrain, and three holes are dug each. The cave is three meters high, eight feet wide, two zhang five deep, the main kiln in the front is slightly higher than the cave on the side, and the main hall is given to the old patriarch and the second uncle and other more than a dozen elders over fifty years old to live.

Although the cave is not difficult to dig, it is helpless to be new, and there is a lack of tools to take advantage of, so ten days of hard work, only such a kiln was dug.

the cave on the left, which serves as a dormitory for boys; The cave on the right is used as a dormitory for girls.

On the day of the official check-in, the soldiers of the Shazao Guard Station rushed to hear the news and couldn't help but be amazed.

Baihu Yuqing was very surprised and very curious: "Excuse me, can this cave really be warm in winter and cool in summer?" ”

Yun Lan glanced at him and patiently explained: "The temperature of the cave does not change much in winter and summer. It is said to be warm in winter and cool in summer because of its good thermal insulation performance. The cave is dug into the hillside, so its "roof" and "walls" are quite thick. When digging caves, choose a place with relatively hard soil, and this kind of thick and hard "wall" is not easy to transfer heat. Therefore, the roof and wall of the cave can neither absorb heat directly from the atmosphere, nor can it directly dissipate heat into the atmosphere, only the mouth of the cave is in direct contact with the outside world. Therefore, the temperature change in the cave always lags behind the temperature change outside, and the temperature difference does not change much. ”

One question and one answer, he asked eagerly, and she answered calmly and fluently.

Yu Qing came in high spirits, and when he left, his face was full of joy and smiles.

Early the next morning, the report about the cave was delivered to Zhuge Tianming.

This report is Yun Lan's handwriting.

It's a pity that he has never read Yun Lan's handwriting, so he missed such an opportunity to recognize each other.

In the blink of an eye, a month has passed.

Every family has dug a cave and settled down completely.

The cave of Yun Lan's house is similar to the specifications of the first cave, the six-hole cave in the front row, counting from the left, the first room is where grandparents live, the second room is where the eldest brother and sister-in-law live, the third room is where the father and mother live, the fourth room is the living room and dining room, the fifth room is the second girl and the little niece Yun Cai live, and the sixth room is where Yun Lan and her two sons live.

There are five caves on the left, which are Uncle Fang's bedroom, Fang Xiaojiang's bedroom, warehouse, stove room, and bathing room; There are three caves on the right, which are occupied by stones, small trees, small seas, small hills, and small slopes.

Fang Xiaojiang, whose original name was Fang Xiaoshan, had the same name as Yun Xiaoshan, so he changed his name.

Thatched huts, built in the corners of the courtyard, are separate for men and women.

The wall of the courtyard is made of rammed loess, which is three meters high, five meters long, and twelve meters wide, and encloses the cave in front and the cave on the face, so that there is no need to worry about someone attacking in the middle of the night.

Sanhe soil is a mixture of three raw materials based on soil. With this mixture, it is possible to ram into the most solid earthen walls. The material used in the construction is a mixture of loess, lime and river sand. After mixing these three raw materials in a certain proportion, they are constantly beaten and turned with a mallet, and then stacked and parked for a period of time to blend and age. With this kind of "triple soil", ram the wall foundation of the tulou, which is quite solid. It can not only bear huge pressure, but also prevent flooding, mountain water erosion and immersion, and has an impregnable defensive function.

The old patriarch and the second uncle nodded uncontrollably, and a smile flowed in their eyes.

When Tan Fuzi heard this, he was full of praise again, and he solemnly recorded the matter of Sanhetu in the codex that night.

The rest of the families also did the same, and built high walls.

The only disadvantage is that because of the topography, each of these caves is almost independent. A family has to be separated by a little distance in between, and only a small number of people can build caves in one place.

The cave of the little uncle's house is adjacent to the cave of Yun Lan's house, and it is separated by a distance of about ten meters. Yun Lan thought of a way and proposed to build two walls three meters high and two meters wide from the gate of her own courtyard to the gate of her uncle's house. In this way, the two families can also hang out at night without worrying about wolves or bad guys popping up suddenly.

The little uncle readily agreed, and soon carried it out.

Other families are doing the same.

At the place leading to the mountain pass, a defensive gate tower was built, and a beacon tower and arrow eyes were set up at the door. Every evening, the doors are closed and locked, and a three-person vigil is arranged in three shifts. On the tower of the city gate, there is a small duty room, with beds and bedding.

Now that the family has a shape, Yun Lan's heart has settled down.

Immediately afterward, she found out the coal mine and solved the big problem of cooking and heating. And at this moment, the thorn thatch in this area is about to be cut down. Fortunately, because of Yun Lan's persistence, every tree within the range of Yunjiaao survived. Every tree that everyone cut down was ten miles away, and there was no Huo Huo to his doorstep.

In fact, Yun Lan also repeatedly emphasized that no matter where the trees are, don't cut them down casually. For every tree that is cut down, there is one less tree, and it does a little bit of damage to the natural environment here. Helplessly, she is not a member of the government and yamen, and she is not the patriarch and village head, so it is inevitable that there are so many people who refuse to obey her. Besides, in every family, there is still a need for some trunks and branches to dry clothes and build shelves for melons and fruits.

Not to mention other people's homes, even Yun Lan's own house, the eldest brother wood and stone Xiaoshu Xiaohai, also went to a place ten miles away and cut down a dozen long branches and came back. The brothers all listened to Yun Lan's words, and did not cut down indiscriminately, but just picked up long branches and cut them in places where there were many trees.

Most of the people also have the same example, only a few people are cut down indiscriminately, directly looking for small trees that are not long, and cutting them back with a few knives.

The second uncle was elected as the head of the village and reported to the Shazao Guard, and the people from the Guards reported to the official government and the yamen for approval.

Yun Lan's question on the management of the bad environment is deeply rooted in the hearts of the people and is deafening to hear. The old patriarch and the second uncle took it to heart, and when they learned that someone was cutting down indiscriminately, they immediately called a meeting of the whole village and criticized those people by name. In addition, a severe punishment was imposed: each person repaired the mountain road leading to the outside of the mountain pass for five zhang, and completed it within five days.

There are six people in total, one person is five zhang, and there are thirty zhang, which is quite a long way. This section of the road is in the worst condition. After the second uncle and the old patriarch discussed, they made a decision and ordered the six people: widen the road by two feet, make the road as smooth as possible, and use Sanhe soil to ram into a one-meter-high wall in the place of sharp turns.

Yun Lan took the initiative to pay for lime and glutinous rice.

Before the Chinese New Year, the six people were finally completed.

The commotion was a bit loud, and the people from the guard came again. Sanhe soil and coal mine attracted Yu Qing's great attention, and he quickly passed the news through Zhuge Tianming.

Zhuge Tianming was on the front line and couldn't come back to investigate in person, but he also took this matter to heart. In his busy schedule, he personally wrote a letter to his henchmen who remained in the palace, telling his subordinates to investigate the affairs of Sanhetu and the coal mine.

Moreover, he specially instructed his subordinates to send 300 catties of cornmeal, 50 catties of rice, 100 catties of pork, 100 catties of Chinese cabbage, 100 catties of radish, and 100 catties of lard to Dongfengling, which was regarded as his New Year's gift to the first batch of immigrants on the Loess Plateau.

When the people of Shazao Guard learned about it, they couldn't help but pay more attention to the people in Dongfeng Ridge. The few people who had crooked thoughts hurriedly pressed down on their thoughts.

You must know that there is a shortage of food in the northwest, and there is a shortage in the barracks. To give such gifts to the people of Dongfeng Ling, he also has to grit his teeth and cut back on food and clothing.

At this time, he didn't know that Yun Lan had also come to the northwest.

Yun Lan calmly received the steward from the palace, Zhuge Tianming's henchman Chang Dongfeng, and wrote a detailed written material for Sanhe soil and coal mines.

After Chang Dongfeng saw it, he was so excited that tears flickered, and he looked at Yun Lan's eyes very eagerly. For the first time in my life, I have developed sincere admiration and appreciation for a woman.

A few days later, in accordance with Zhuge Tianming's instructions, he sent ten chickens, one hundred catties of cornmeal, and ten sheepskin jackets to Dongfengling. And the roll call is all for Yun Lan.

The people of Yunjiaao were lively and lively, and had a hard but warm New Year.

The cold winter finally passed, and the spring breeze finally blew the green earth.

At the beginning of spring, Yun Lan planned to plan the places around his cave into several areas: apple orchards, jujube orchards, sunflower orchards, peach orchards, flower gardens, medicine gardens, and mushroom orchards.

Cultivate good fruits, mushrooms, flowers and plants, send them to Wangfu Street, and they will definitely be sold for a good price.

Wangfu Street is the street where the Jin Wangfu is located, and all the people who live there are dignitaries. There, there is a bazaar, a small market every three days, and a large market every five days. The bazaar, in fact, is two miles away from the palace, and there is a roadblock set up at the corner of the street. After passing the inspection, ordinary people can enter the bazaar on Wangfu Street to buy and sell.

These news were all from the soldiers when they were on the road. Perhaps, because the two children are still young, smart and cute, those soldiers have no defense, except for very confidential things, some of them have not said a lot.

Through her son's retelling, Yun Lan learned a lot about the customs and customs of the northwest. It's just that the focus of a child is different from that of an adult, and there are many things she wants to know, but she can't know.

For example, the desolation of the Loess Plateau was unclear to her before.

In addition, there is actually a misconception that the rumored land is very barren and not true. It should be said that in most places, the thickness of loess is very deep, the loess particles are fine, the soil is soft, there are rich minerals and nutrients, and the fertility of the land is sufficient, which is actually very conducive to farming.

In Yunlan's cognition, the Loess Plateau, basin and river valley in the previous life have a long history and are the cradle of ancient culture. Rich in minerals, coal, iron ore, rare earth ore reserves are very large.

The Loess Plateau in front of you should not be much worse.

In her previous life, the Loess Plateau in her cognition was affected by the dry and cold air masses of the polar regions in winter and spring, and it was cold, dry, and windy sand; In summer and autumn, it is subject to hot and heavy rains, many geological disaster points, thick and loose soil, broken surface, changeable weather in summer, and debris flows, flash floods and other disasters are easy to occur in heavy rains.

However, in ancient times, the environment of the Loess Plateau did not suffer great damage, and there were still vast forests, verdant grasslands, and a wide variety of wild beasts.

It stands to reason that the Loess Plateau in front of us should also have vast forests and grasslands, which is reasonable. Could it be that this place, once upon a time, was a densely populated place? So, the destruction of natural resources has led to the situation we are in today?

This is not impossible, it is said that more than 500 years ago, the continent where the Yan Kingdom is located once suffered a great chaos. Not to mention other countries, the land of Yan alone has been divided into twenty or thirty countries. countries and countries themselves, perennial hostility; Within the country itself, there are often rebels. As a result, the people were displaced, the day was precarious, the Yamen people were floating in trouble, and all kinds of archives, precious documents, books, etc., were destroyed in the war.

In other words, there is a cultural fault, and the civilization in this land has almost been destroyed. The historical information about this land is very vague and even very confusing. Many, many precious past existences have been erased, gradually forgotten by the world, and disappeared in the long river of history.

However, no matter how bad the environment is, some things still remain. If nothing else, there are definitely coal mines!

Yun Lan's heart was cold, and suddenly there was a small flame.

Hehe, there is a spiritual spring, and there is a coal mine, what else does she have to worry about?

With coal, the firewood thing is equivalent to being solved! Don't worry anymore, you'll freeze to death in winter! With coal, it is also possible to build greenhouses to grow out-of-season vegetables and fruits, which is another large amount of input. With the villagers who came over from Feng County, she still has confidence that she can live a life where she can be fed and clothed!

And the eastern part of the place where the first immigrants were divided happens to be the place with the best climate on the Loess Plateau!

However, Rao is like this, and the people of the few dozen or so small villages here are also living a miserable life.

Soil erosion caused by over-cutting and overgrazing, and unreasonable land use, leads to the deterioration of the natural environment.

The Loess Plateau is vertical and horizontal, the form is complex, the loess plateau, beams and ridges are widely distributed, and the three major landform types of mountain, plain and Sichuan are the main body of the Loess Plateau, which is a kind of broken surface.

In this way, this place is indeed much more headache than other places, and it is not so suitable for the survival and development of human beings. It's just that Yun Lan has always firmly believed that no matter how bad it is, there must be some kind of advantage and attraction.

Loess is formed in different climatic conditions, so it has different appearance colors. Based on the vertical variation of the loess profile color of the Loess Plateau, it can be roughly divided into four main color segments from bottom to top: the first section, light reddish and yellow segments; the second segment, brownish-yellow segment; the third paragraph, gray-yellow segment; The fourth segment, the brownish-yellow segment. The color of loess changes from bottom to top from red-yellow-brown-yellow-gray-yellow-brownish-yellow.

In other words, it's an extremely beautiful place!

Anyway, Yun Lan liked it at first sight!

She made up her mind that she must make good use of the advanced scientific concepts she has mastered to take scientific and effective measures to deal with the problem of soil erosion on the Loess Plateau.

She called on and led everyone to plant trees and grasses, vigorously build shelter forests, increase the coverage and coverage of vegetation, improve the vegetation of natural grasslands, build horizontal terraces, build reservoirs and so on.

Zhuge Tianming was in the restaurant and happened to meet Yunkai and Yunqing.
