Greenhouses are easy to build. How does it transmit light?

To grow, photosynthesis is required. It's a pity that the glass that Liu Bei has been thinking about has been difficult to realize. Therefore, in terms of the light transmittance of the greenhouse, Liu Bei needs to think carefully.

The warm tent used for winter bathing at home is made of nitrate and dehaired cowhide to prop up on all sides. Hazy and translucent, perhaps......

Liu Bei then found Su Bo and asked carefully.

"It's both warm and light." Su Bo smiled: "What's so difficult about this. Just like the warm tent of the young owner's bathhouse. You only need to use nitrate to remove the sheepskin, sew it into a leather sac, and then support the bamboo inside, this thing can be made. ”

When I asked, I learned that at this time there were not only skins for water, but also leather boats for crossing the river.

According to the Book of the Later Han Dynasty, when the captain of Huqiang led the troops to cross the river, he "sewed leather bags for boats". "Water Jing Note: Ye Yu Water Chapter" also has: "In the twenty-third year of the Han Dynasty, the king sent troops to the south on a leather boat". The so-called leather boat refers to "using sheepskin as a bag, blowing air and floating in the water".

Cowhide is not easy to get. but there are many sheepskins.

So he ordered them to be bought and sewn into leather bags.

The framework is easy to do. Select perennial moso bamboo, bend in an arc. The two ends are inserted into the soil and arranged in such a row that the frame of the greenhouse is completed. Then cover the leather bag and pull it tightly on all sides. As the sheepskin sac becomes longer and longer, the light transmittance of the greenhouse is getting better and better.

Heating up is not a problem. A stove is enough. The most important thing is smoke exhaust, and it is also connected to a long pipe with moso bamboo.

Divide all kinds of medicinal seedlings in the flower garden at home to the Zongren. After explaining various matters, the first greenhouse medicine garden was completed.

The people of the sect who pulled out the hemp field should be cherished. The reason why he chose this is because there are two fields in his yard, where rice is planted in the front and hemp is planted in the back. There are no mulberry trees. That's when he agreed. If you cut down mulberry trees, or destroy rice fields, plant medicinal herbs instead. Not to mention the people, even Liu Bei couldn't bear it.

The young prince is the nephew of the family, even if Bai Yuwei is majestic and mighty, the neighboring sects still gather one after another. The house of the Zong's family was surrounded by three floors, inside and out.

The good end of the sheepskin sac, the whole piece is cut open from it, not to mention. They also sew each other into a large piece of skin, wrapped around several curved bamboo poles. What is the young prince going to do?

Wave your hand to make everyone stand back. Bai Yuwei then escorted Liu Bei out of the Zongren mansion.

Seeing off the young prince, the crowd poured into the courtyard. Surrounding this sect person, he didn't ask any questions. Zongren just smiled. The mind is full of what the young monarch said about the cash cow and cornucopia pointing to the medicine garden.

I watched the young prince grow up, how can I not believe it!

I thought that insufficient light transmission was a big drawback. Unexpectedly, many commonly used medicinal materials prefer shade and avoid light. The leather bag is of great use!

It's a pity that Liu Bei knows very little about medicinal materials. This made Mayor Geng Yong spread Lou Sang all over the place. Words: Those who can offer unknown medicinal materials should be rewarded.

As soon as this notice came out, the people of Yi responded one after another. or hearsay, or the history of barnyard officials. Or they poured into the market building with half a torn volume of medical books. The words are conclusive, pointing to the sky as an oath. Geng Yong greeted him with a smile, and those who came did not refuse. It is recorded one by one. Send it to the Yishe Medical Center, let a group of good doctors carefully screen and check, and then cash the bounty is not too late.

Cen grass (Houttuynia cordata), honeysuckle, skullcap, coptis chinensis...... They were offered by the people of Yi. But there is no panacea-banlangan. It's a shame.

Liu Bei bought it with a lot of money and cultivated it carefully in his own flower room first. When the seedlings grow, they are transplanted into the greenhouse of the Zongren. Why do you need medicinal herbs to grow! Hearing that Shaojun was waiting for a lot of money to ask for medicine, the people of Yi looked for Su Bo and asked to build a greenhouse medicine garden.

Subers did not refuse. The simple greenhouse of the young owner will be continuously improved and carried forward.

For a while, sheepskins were all the rage, and they were sold out of the Northland.

Even the meat is not as expensive as the skin!

Wu Lian asked: How about the grassland sheepskin?

Liu Bei replied: Is it the kind of hair curly?

Ulian nodded repeatedly.

That's fine wool!

Well, sheep shearing!

Prairie sheep are said to be sheared twice a year. An adult ram can get an average of four pounds of wool. Adult ewes get an average of three pounds of wool. Fur is also a good raw material for fur.

Is there a difference between wool weaving and linen brocade?

Why not give it a try.

Liu Bei said to Wu Lian: Yes. And leave the wool behind.

Wulian Daxi: A word is a certainty.

So he sent someone to send a book to the king's brother Wuyan, and asked him to collect more sheepskins and sell them to Lousang with the boat.

After getting along for a long time, Liu Bei discovered. At this time, Wuhuan really doesn't think of himself as a Hu person. It's the people of the Han Dynasty as it should be. This surprised Liu Bei. Wulian's daily performance made Liu Bei feel a trace of indescribable pride in this devastated and stormy empire.

Once upon a time, Siyi was proud of its sinicization.

Isn't it similar to the people of China in later generations, vying to be foreigners?

If the sinicization can continue forever.。 What about the world?

bought some good fruit gifts, accompanied by Geng Yong and Cui Jun, and went to the Yishe Medical Center to visit the housekeeper who was getting better.

The young prince and marquis are light on wealth and righteousness, and there is a style of Meng taste. The steward's father is far away in Beihai, and he has also heard of it. I can survive today, thanks to the help of the young prince and the marquis. I also come to see it from time to time, and I will do the gift of the younger generation. It is because Guan Ning and Lu Zhi are both disciples of Chen Tingwei. In terms of seniority, Liu Bei not only wants to call Uncle Guan Ning, but also calls Father Guan Uncle Uncle.

The father of the steward liked Liu Bei very much.

It is often mentioned in front of Guan Ning.

In other words, the young prince has the posture of a hero.

Guan Ning listened silently.

The great Confucian Chen Yu is proud of the spring breeze.

Between celebrities and gentlemen, fighting but not breaking. Lousang Academy, Lu Zhi arrived first. It's Liu Bei's mentor again. Take advantage of the right time and place. Today, there is a dragon in Beihai, and the three of them worship the door together. All of them are young and talented, and they are good at governing the world. The style under the door is prosperous, and you can't like it.

The forum war of words is even more invincible. Cui Yu, Liu Chong, and Lu Zhimen are not opponents.

The forum is inside. It is surrounded by the round building of the school altar and is in the middle. Whenever the forum starts, the students upstairs rush out of the school building and huddle around the railing to watch the battle. Although you don't learn to perform martial arts to buy tickets, but with Gongsun Zan and Tian Shao's youngest son Tian Hua here, how can you miss the game of "drama and taking people's money"? At that time, people fought cocks and lackeys, and gambling was prevalent. Students are no exception. 'Gaming' is also a game. So the bets were made. It is said that Gongsun Chan has lost particularly badly in recent days.

Also. Beihai Yilong is invested in Chen Yu's door, what suspense is there in this 'Bo Theory'? A one-sided bet on Beihai to win!

The so-called 'no first, no second'. Lose one or two games, and still be able to maintain self-cultivation. Now that he has been defeated repeatedly, the only thing left is the calf nose (bull nose pants), who can bear it!

Beihai Yilong, right? Wait!

There was a sharp increase in the number of letters. can be busy with a lot of assassins, officials and Cui Jun.

A closer look can't help but wonder.

Students who lost red eyes, this is going to move the rescuers!

Who doesn't have three or five friends, relatives and friends? As a result, the carriages and horses galloped on the official road of Zhuo County, and they all rushed to Lousang!

As a result, it was also a fiasco!

A dragon in the North Sea is famous, and there is no difference for a while.

It even alarmed Liu Bei.

The reason why 'Bo Theory' is called 'Bo Theory', not 'Bo Debate' or 'War of Words'. It is precisely because this is the Lousang Academy. I've only heard of 'sitting and talking', but have you ever heard of 'sitting and arguing'? Therefore, the use of 'argument' does not require 'argument'.

Since it is about the Tao. It's in the academic field. A dragon in the North Sea cites scriptures and witty words. And energetic, intelligent and quick-witted. He has been fighting for a long time, his thinking is clear and meticulous, and there are no flaws. arguing with it, young, invincible in knowledge; Old age, lack of energy; Those who are young and strong are not as knowledgeable.

What to do!
