Li Huan slowed down and asked in a low voice, "The prince came to inspect the imperial village, don't make any mistakes." ”

Wang Cundao: "After receiving the notice, I could only hurriedly clean a few important places and drive the idle people in the village to work in the fields. The prince has never seen farming, so there should be no problem, right? ”

The main courtyard of this Huangzhuang is covered with blue bricks, and the courtyard is also paved with bluestone strips, which looks very neat.

Li Qi entered the courtyard, which was a two-hall courtyard, with five main rooms in a row, and the main hall in the middle was one piece higher, which looked more like a temple he had seen. There was a pond in the courtyard, but it was almost dry, and the pond was surrounded by weeping willows and a few apricot and peach trees.

The door of the main hall was open, and there were two maids standing next to it, Li Qi nodded, and walked into the middle hall first.

This central hall is more than a meter higher than the ordinary room, and there is a desk and a bench in front of it, and a set of colored porcelain tea sets are placed on the table. There are also two sets of tables and seats on both sides, the style is the same as the front, only the seats are shorter, only allowing a single person to sit down, not to lie down.

The name of the chair only began to appear in the Tang Dynasty, and it was originally called Hu Bed, which only appeared in China around the Northern Wei Dynasty.

However, in the main hall of the Jinyang Palace, the interior furnishings are similar to the Japanese-style rooms of later generations, and the wooden seats are similar to "tatami mats". The Japanese-style room furnishings of later generations were handed down from the Tang Dynasty, but the neon people's brains were relatively dead, and there was no major improvement.

Kneeling was actually very uncomfortable, so this kind of "Hu bed" slowly became popular in the Tang Dynasty.

The so-called "chairs" now do not have backrests, only armrests that resemble bed gangs, but are much wider than later chairs and can be used to lie on them.

Li Qi sat down on a chair in the main hall, and then said to Wang Cun: "You tell me about the situation in the manor first." ”

Wang Cun stood about three steps away from Li Qi's front, stood with his hands down, and replied respectfully: "Back to Your Highness, this Lutai Huangzhuang is one of the several imperial villages that Emperor Wu was awarded after quelling the Huangchao Rebellion, with a total of more than 3,000 hectares of land, and it is also in charge of the mountain forest royal hunting grounds in Lutai Mountain. At present, there are 782 households and 2,976 people, including 1,271 young and strong. ”

He said that the figures did not include women, and in ancient times the population did not include women.

"What is the land of the manor?" Li Qi continued to ask.

"Back to the prince, the rain has not been abundant in the past two years, and the harvest is not good, last year Lutai Manor produced more than 10,000 stones of grain and wheat, and more than 40,000 stones of millet, of which 50% was paid to the palace as field rent." It can be seen that Wang Cun is quite familiar with the situation in the manor.

After hearing this, Li Qi frowned: "How can the yield of wheat be so small?" ”

"Back to the prince, this wheat field needs good paddy fields, and the harvest in the dry fields is not as good as millet and millet rice, and only the fields on both sides of the river beach that can be watered with water wheels can be planted, so the yield is not much.

"Didn't there be a dam on the manor to bring water for irrigation?"

Wang Cun shook his head: "The cost of damming this barrage is huge, and the manor can't afford it at all, so there are only a dozen reservoirs built. ”

Li Qi nodded: "I still want to build a dam, go around it in the afternoon, and then let the people from the capital water supervisor come over and select the dam site." In the summer, when the river is smaller, it is time to build the dam. ”

After lunch, Li Qi rode his horse and walked around the dirt road of the manor. Lutai Manor is located at the foot of Lutai Mountain, excluding wasteland and mountains and forests as royal hunting grounds, there are more than 3,000 hectares of fertile land alone. The Tushui River runs through the center of the manor, and because of the dry weather, the river is very shallow, only waist-deep, and can be waded through on horseback.

The woods on both sides of the river are lush and green, like a green brocade belt, stretching from Lutai Mountain to the direction of Yuci County.

Due to the small current, the waterwheel on the riverbed stands quietly and is no longer usable.

In the east of the river, the rainfall is very uneven, the rain is mainly concentrated in autumn, and in addition, at the beginning of spring, the snow in the mountains melts, and the amount of water in the river is large, in addition, it is not easy to use river water for irrigation for most of the year. According to Li Qi, only Yangqu County and Jiangzhou have built dams that can divert water for irrigation.

Li Qi considered building dams and embankments, not only for agricultural irrigation, but also because of the need for water power as a driving force.

In his previous life, the school he studied at was called Hohai University, formerly known as a water conservancy college under the Ministry of Water Resources.

Returning to Jinyang from Lutai Manor, Li Qi hid in the study and did not go out for three days.

Hydraulic turbines were actually invented in the pre-Qin period, but there have been no major improvements over the centuries. In the Jiangnan area, there are water mills and water-powered rice machines. What Li Qi painted is the kind of wooden water turbine installed during the production team when he visited the Hongqi Canal in Linzhou in his memory.

It's one thing when you visit, but when you design on a drawing, you still have a lot of problems. Li Qi knows the operating principle of the turbine, but when he actually designs it, it does not mean that the drawings he draws can make qualified machinery.

Everything needs to be improved by practice.

Due to the strict restrictions on the use of iron tools over the years, the carpenters of the Shaofu Prison have become accustomed to not using iron nails when making woodware, but Li Qi did not care about this, and used many iron accessories when designing machinery.

In addition, some carpenters and blacksmiths were transferred from Jinyang Prison, and in the back courtyard of the palace, they began to give ideas to the craftsmen, hoping to develop power spinning machines and power looms earlier.

"Food, clothing, shelter and transportation" is the most important material needs of human social activities, with the current situation, most people's life goal is to be able to eat a full meal, wear decent new clothes for the purpose, not to mention housing, ordinary people can have a mud house to accommodate is already very good. As for the line, horses, cows, donkeys, and cars and boats are not something that ordinary people can enjoy.

No matter how poor everyone is, he will put a fig leaf on his body, even if it is a sack, unless the person is a madman......

Cluck-la......-la

In a creaking sound, a hand-cranked spinning wheel turned. In the Han Dynasty, the manufacturing technology of this spinning wheel was already mature. With the rotation of the wooden wheel, the yarn is rotated, and the cotton roll in the hand is twitched and twisted into yarn. Li Jiqi's request to the carpenters was not difficult, and the runner drove the sixteen spindles to rotate at the same time.

This is equivalent to one in which can be used by up to sixteen people.

As for the number of spindles driven by the spinning machine, it will be slowly increased in the future.

This kind of transformation is not very difficult, that is, it is easy to change the original horizontal spindle to a vertical one. Before, it was just that no one thought about it. Craftsmen make spinning machines, but they don't use them, and women don't know how to do it...... The social division of labor that has formed in China is a big mistake for men not to go to the kitchen and women to spin and weave.

Limited to the strict use restrictions of power systems and steel products, most of the spinning wheels in Huaguo are still single-spindle spinning wheels, and some multi-spindle pedal spinning wheels have not been popularized due to their lack of popularity. In the previous life, it was during the Song Dynasty, due to the development of the commodity economy, there was some progress in textile technology, and there were dozens of spindles of water-powered spinning machines.

Li Qi just advanced this process by more than 100 years.

With a slight stroke, it took the craftsmen only three days to make a 16-spindle spinning machine, except that, like a stone mill, it had to be pulled by a donkey......

Their ultimate goal, of course, was to use a water wheel to drive the textile machine to work.

After the successful development of the spinning machine, the transformation of the loom is actually simpler. The so-called "shuttle" and shuttle plate have long been invented, and the only improvement is that the width of the cloth can be increased due to the strong power. After looking at the loom, Li Jiqi found that there was not much room for improvement in the loom.

Since the preparation of mechanical spinning and weaving is required, the requirements for the original are higher than the original, and the equipment such as carding and carding for processing the original, removing impurities, and finishing the quality is also essential.

These devices can only be improved slowly in later practice......
