The Lord of the World Begins from the Siheyuan

Chapter 147 That's Very Useful

After work in the afternoon, Li Ming asked someone in the printing room for a scrapped stencil.

Then he went back to the security department, got an application report printed in 100 copies, got Chen Liuman to sign it, and Director Yu signed it.

Chen Liuman also praised Li Ming for not forgetting to work even when he asked for leave.

Li Ming used stencils to engrave a portrait in the small world. Even though the small world was a little small, it was still recognizable.What was left was the contact address of the Security Section of the Steel Rolling Mill.

He did it easily, but it was not so easy for others to engrave it.

The person who engraves must use a special "stylus pen" to make strokes carefully, and the wax paper is placed on the special steel plate.

The steel plate has one side.There are also two sides, the twill side and the cloth side are suitable for different fonts.

Novices can only practice with waste wax paper, and they can get started only after they are proficient.

Because if it is light or heavy, it will not work, and if it is light, it will not penetrate the wax and print clearly.If the stencil is too heavy, it will be scratched, and if the stencil is torn, it will not be suitable for printing.Later, there was a repair fluid to repair, which can be regarded as the demand for product technology.

A wrong word can be corrected. If it is not important, such as a test paper, just draw two more strokes to show that the word is invalid.

Important content has to be modified by melting wax.If it is too wrong, it can only be re-engraved.

Engraving this ink stencil is a careful job, which is a test of patience.

Some people carve it out like a primary school student's handwriting, and they can only say that they can recognize it and use it.

Some people's engraved characters are correct, beautiful and generous, which looks like printed, which is very admirable.

Picking up the wax paper discarded by the teacher is also something that some students prefer to do.Why pick it up and use it, of course I want to read the papers in advance!
Ink scrolls accompanied the students until after 2000.

During the exam, I had to roll up my sleeves or put something on it. After the exam, my elbows were covered with black ink.The smell is quite fragrant.

Li Ming carried a bag of fruit and the application report, and asked the people in the printing room to help print it.

When he got the waxed paper, the printer even boasted that it was engraved by a master engraver.

The number of copies to be printed is not too many, and it is for investigating cases. After the printer finishes printing the leaflets that are being printed, he is asked to jump in the queue and print them first.Of course, the contribution of fruit cannot be denied.

The mimeograph machine is actually very simple.

On one side is a thick glass bottom plate that can hold white paper and a screen frame with springs that can move up and down.On the other side is the ink palette and ink roller.

When mimeographing, paste the engraved wax paper on the screen window frame, press the top of the wax paper into the groove with a thin iron rod, and then fix it with the clips around the screen window frame.

Li Ming was watching the printer's operation, and it was done in twos and threes.

The printing ink was already adjusted, and the printer pushed the ink roller hard to make a trial print, and it was pitch black.

The printer lightened his pressure and tried printing another sheet, but it was still a bit too dark.

The ink was a bit too thick, so the printer poured in an appropriate amount of kerosene to thin it out, and this test print came out just right.

100 copies will be printed soon.

Li Ming expressed his thanks.

He went straight to the third canteen with the printed portrait.

They called Shang Shazhu, and the two went to the Jiaodaokou Public Security Station. It happened that Director Zhang had gone out, and Deputy Director Niu had a rest in the afternoon. The instructor helped arrange people to handle it.

Li Ming also made it clear to the trainer about the reward money and meat. It is inappropriate to declare reward money to the outside world, and the trainer understands this taboo better.

After the matter is done, Silly returns to the rolling mill.

Li Ming was going to check to see if the two young men had released Xu Damao's news as he said.

Qin Huairu had already shown it in advance, if he didn't fix Xu Damao, it would not be in line with his usual style.

When he arrived in the west of the city, he still put on some make-up, and quickly found the two young men. After asking, Li Ming went to the countryside by bicycle to see the effect.

In the small restaurant where the commune is located, I ordered two or two noodles and cut a sausage for [-] cents. It was not meal time, and there were no birds at the door.

Li Ming also pretended to ask if there was a movie showing recently, and then talked about the person who played the movie, and Xu Damao's gossip did spread.

After eating the noodles and paying for the food stamps and money, Li Ming was ready to go back to the city.

Li Ming didn't check other communes. In the era of lack of entertainment, gossip about popular figures like projectionists spread quickly.

There was a river on the way Li Ming cycled back to the city, so he stopped to fill up the freshwater pond in the small world first.

Then he also washed a part of the saline soil with river water to reduce the salinity, and the water was discharged while entering the water.

With a water flow rate of 20 cubic meters per second, Li Ming collects 10 cubic meters per second, which means 1 cubic meters in one minute. Each mu of land is washed to a depth of 600 meters, and 0.5 mu of land can be soaked in water in one minute. After washing 1 mu of land, it can be returned City, because enough is enough.

The remaining saline soil is of great use.

Li Ming's growth of plants in the small world consumes a lot of inorganic and organic matter in the soil.

After cultivating several batches, if the soil decomposed from the crops is not mixed back into the soil, the remaining soil in the field is poorer than the soil in the tropical rainforest, and it is a 'white soil' with no nutrients.

In the future, he can use saline soil to mix with the consumed 'white soil' to replenish the inorganic and organic matter in the soil.

And he can also use these high-concentration saline soils to mix low-concentration saline-alkali soils for testing salt-alkali-tolerant crops.

Saline-alkali-tolerant crops are in great demand across the country.

Li Ming rode his bicycle directly back to No. 95 courtyard.He will reward those two next time, and he will give it if he promises.

It was past 6 o'clock in the afternoon, and people who got off work came back one after another.

Li Ming helped the car into the front yard, and saw Yan Bugui playing chess with Uncle Dong who was upside down.

These two are also half a catty to eight two, and they are both masters who love to regret chess, and they can play a game of chess for a long time.

Li Ming helped the car to the two of them, "It's better for you two to relax."

"School is about to start. I'm going to school for a meeting today. When I get back, I'll play a game with Lao Qin." Yan Bugui explained, but he was worried that Li Ming, a rich man, would mistakenly think that he didn't bother looking for a house.

Li Ming chattered, "The time flies so fast, it's good to start school, this kid is playing like crazy."

Yan Bugui didn't take it seriously, "It's time to play as usual when school starts."

Uncle Dong didn't care about the chat between the two, "Old Yan, I'll eat you."

Yan Bugui hurriedly said: "No, it doesn't count, this step doesn't count. I was chatting, so I didn't see it."

Uncle Dong said with a smile: "It's nothing, wait for you for a long time, who told you not to see it."

Yan Bugui patted his thigh and said, "I'm just not paying attention."

Uncle Dong said cheerfully, "It's because you can't concentrate."

Just now Uncle Dong sneaked an extra move, but Li Ming didn't try to break it.

After helping the car back to the door of his house, Li Ming opened the door and entered the house.

He lies in bed and reads, but his mind is actually in the small world. On the 10 mu of land in the northern area, alfalfa is growing rapidly, blooming and bearing seeds, and the seeds are quickly rooted and sprouting, and the 10 mu of land will soon be filled.

The 10 acres of alfalfa grass are each separated by 2 meters. They are rich in nutrients and free from diseases and insect pests. Their growth depends on their own genes.

Li Ming kept planting and picking plants in this way.

After 10 mu of land becomes 'white soil', it is mixed with 10 mu of saline soil next to it, 10 mu of normal soil and 10 mu of saline-alkali soil.

Then it was sowing and spawning, and both normal soil and saline-alkali soil were sown.
