In fact, without the government to provide white stacked seeds, there is no necessary training guidance and purchase indicators, and it is still very unreliable to grow white stacked flowers by yourself.

Cotton seeds need to be depiled with sulfuric acid, and they must be soaked in hot water to promote germination. The former is a trick invented by Hong Tao based on later agricultural techniques, and the latter is a trick summed up by Uighur farmers for generations, and the combination of the two should be better.

After entering May, the good news came one after another, making Hong Tao a little dizzy. First of all, the construction of Suzhou City was completed, and I didn't see the quality with my own eyes, but I used one word in the letter from Monday and Sunday and Wang Da, which is indestructible!

Thinking that with Wang Qi, an architectural genius who integrates China and foreign countries, the new Suzhou City will inevitably not become a tofu scum project.

Then Wang Er's statistics were released, and the sowing of white stacks of flowers in the pioneer fields near Liangzhou City was declared initially successful, and the seedling emergence rate was very high, even higher than that of the Uighurs.

This left several Uighur peasants puzzled, and they had to blame the land, saying that it was too fertile. In fact, this is inseparable from the effect of sulfuric acid depilation, the principle, Hong Tao is not clear, anyway, the cotton farmers in later generations did this, there must be a reason.

Then Wang Si and Wang Wu of the chemical laboratory worked together, and after more than two months of continuous testing, they finally got the anhydrous ether out. Wang Shixi was too curious, so he had to try the intoxication effect that the official said, but he was sent to Liangzhou City overnight, and he was still in a semi-coma when he saw Hong Tao.

The consequence of this was that he was removed from his status as a laboratory tester for a month, and was responsible for cleaning the laboratory and yard. Those who dare to challenge the rules will be punished, regardless of the consequences.

Before Hong Tao's smile fully bloomed, Huang Huai'an came to offer treasure again. There was no breakthrough in the soil milling machine and the lathe, but he transformed the spinning wheel, and the improvement was not too big, only four times!

The spinning wheel is a tool for twisting fibers such as silk and hemp into threads. At first, people twisted the thread by hand, which was too slow, and later invented the hand-spinning wheel, which was twisted by spindles, which was much faster.

Liangzhou Woolen Mill is the production method used, first turn the processed wool into wool, and then use a loom to weave into cloth to make wool cloth. The woolen output of a woolen mill does not depend on the number of looms and whether they are advanced or not, but on how much wool can be spun by the spinning wheel workers.

Compared with silk and linen, wool has one more use, it can be woven by hand without weaving through a loom, sweaters and pants, but there is no difference in the spinning process.

But cotton cloth does not have this advantage, no one will use cotton thread to weave clothes to wear, it must be woven into cloth to be useful. In this way, the spinning thread becomes a link that limits the output of the loom, which is too slow.

There is a large spinning wheel in the Northern Song Dynasty, which can be twisted with dozens of spindles, driven by water power, and can spin 100 catties of silk and linen in a day and night. However, the thread spun by this spinning wheel is too fine, and it can be used for ultra-long fibers such as silk and twine, and the fibers of wool and cotton are relatively short, so the spinning thread cannot be made, and the strength is not enough, so it is difficult to use it in looms.

Huang Huai'an's transformed spinning wheel has four twisted spindles, although the speed is not as fast as the big spinning wheel, but the thickness of the spinning thread can be adjusted. After being equipped with a gearbox, it can still be driven by a water wheel, which temporarily solves the problem of insufficient production capacity in the spinning link. It cannot be said that the output has been directly increased by four times, but there are still two or three times.

Why do you say temporary, because things are always evolving, the spinning wheel is upgraded, and soon someone will be thinking about the loom. As long as there are enough interests to drive, the loom will be upgraded sooner or later, and then the Huang spinning wheel will fall behind again, and it will have to continue to upgrade. This is how human science and technology have been developed in a staggered manner with you taking a step forward and I chasing a step at a time.

"Official, my subordinates have tried it secretly, this thing is really sharp, the one-inch thick pine board has been pierced through such a big hole, and the steel armor of Weiqiao Town can't prevent it. It's just that the distance is too poor, and I can't control the accuracy from fifteen steps away. ”

As a leader in science and technology, Wang Datou is definitely not far behind, he also came to offer treasure with a leather bag, but he was still sneaky and spoke very quietly.

Inside the bag was a front-loading pistol about a foot long, resembling a flintlock pistol in 16th-century Europe. In fact, it is a flintlock pistol, the reason why it is like this is completely the credit of Hong Tao's hand-drawn paper, Wang Datou faithfully restored everything on the drawing, not bad at all.

And a little more, silver jewelry. Wang Datou's problem seems to be impossible to change in a lifetime, no matter what he does, he must always be perfect, even if it is just an experiment, he still has to inlay exquisite silver jewelry on the body and handle of the gun to reflect his good craftsmanship.

"No matter how long the barrel is, it still can't be made?" Hong Tao is not even interested in trying this thing, it is not practical, and it is not even as good as a crossbow on the battlefield. There is no cost advantage, it is completely hand-built by craftsmen, and the output is very low.

"The pipe can be made, but the three rifling wires inside are not easy to get, and there will be deep and shallow if there is a slight deviation in the knife." As soon as he mentioned this question, Wang Datou's crippled right hand trembled, and he really wanted to go into battle in person to redeem the loss of reputation.

"Don't be in a hurry, take your time, if you have difficulty in thin pipes, make thick pipes first, practice makes perfect. This thing can't be put in the hands of this official, and it will be melted down immediately after going back, and the slightest rumor can't be revealed, otherwise you and I will face the disaster of death. ”

Hong Tao is really not in a hurry, even if Wang Datou makes the rifled barrel, he can't get a suitable propellant and primer, and he is still a waste.

The starting point of the craftsmen in Huangzhou was already very high, at least higher than that of the Jinhe Empire back then, and all they lacked was experience. This thing can't be rushed, and she has to let her mother play to hone it slowly.

In fact, with their technical reserves, it was more than enough to manufacture a front-loading smoothbore gun, but Hong Tao didn't want to do that. There are steel crossbows, siege crossbows, box cars

With thunderbolts and oil bombs, the new army can already crush all the armies of the same era in terms of equipment, and there is no need to replace smoothbore guns. It wasn't much more advanced than the current weapons, and it was so expensive that it didn't make much use.

Can you get a few smoothbore guns out? Technically, it is possible, but the actual situation does not allow it. The new army could no longer strengthen its combat power, which would make the courtiers more afraid, and even the emperor would have to have an idea.

All research on thermal weapons is only in the experimental stage, and even if the test is successful, it can only be adjusted in terms of production process, and mass production is not planned unless necessary.

Should you go to the chemical laboratory to test the cotton wool, or go to the Liangzhou Machinery Factory to perfect the barrel processing technology, or go to the woolen mill to see the Huang's spinning wheel, or inspect the cotton fields?

"Melons don't grow well...... I said, Dashang, you have injuries to your hands and feet, just rest for a while if you have nothing to do, and you don't lack those mouthfuls of melons and fruits to eat. Before Hong Tao could figure out what to do first, Gao Yu limped again. He really didn't make any new discoveries, he was here to solve his puzzles.

This guy also belongs to the master who can't be idle, the chemical laboratory and glass workshop in Liangzhou are newly built, and there is no official production task, so he has built a greenhouse next to it, planning to continue to grow melons and beans.

The reason why he came to Hong Tao for help was very simple, the melon seedlings in the field were better than the carefully served ones in the greenhouse, which made him puzzled.

"The teacher is not saying that when you encounter unreasonable problems, you must find a way to understand them clearly, curiosity is the fundamental motivation to do learning......

Gao Yu saw that the teacher was unwilling to give an answer, so he had to sacrifice his trick. This trick is known as nirvana, which is summed up by the children through a lot of practice, and it is very useful to deal with the adoptive father.

“…… Let's go tell the wasp to prepare the horse! Hong Tao gritted his teeth several times and resisted the urge to beat Gao Yu. This group of children learn well and slowly, and they learn really fast, even an honest person like Gao Yu knows to block himself with his own words.

The area of the greenhouse is not as large as Mawei City, a total of less than half an acre of land, and the growth of melon seedlings inside is not bad, and the green looks healthy. But Gao Yu said that he also planted a few melon seedlings to the west of the laboratory, and planned to increase the yield in the spring and summer.

The problem lies in these melon seedlings, they grow better, they are so green that they are black, the plants are taller, and the leaves are fatter, which is really a bit annoying.
