Although Fubo didn't understand the pistil and what the male ears were, Li Yunrui explained very vividly. Fubo was also a veteran of a crotch. When he heard it, he understood Li Yunrui's meaning.

This is a compulsory course for junior high school students in the future, but in Daming, it is Black Technology.

The reason why Li Yunrui gave artificial pollination was that the corn he was afraid of planting was not good.

In later generations, he once read a report in CCTV's "Agricultural Channel", which explained that corn is a goblin crop, male flower above, female flower is underneath.

The probability decreases, causing the corn to be unconvinced. The best solution is to use manual auxiliary pollination to increase the chance of pollination.

The corn seeds that were hard to get, Li Yunrui did not want to work hard. In order to ensure that everything was lost, he took out artificial pollination.

"Master's knowledge is really unpredictable!" Fubo smiled and said.

"Fubo praised, I was also on Jiangxin Island. I was idle and boring, and I discovered by chance ..." Li Yunrui smiled and said.

Li Sanghai listened to it, a little dizzy, did you go to the same Jiangxin Island as the young master? He never found that the young master was on Jiangxin Island, what food was planted ...

Li Yunrui said with the manual pollination, and talked with Fu Bo again, and took Li Sanghai with the potatoes.

"Master, when did you give the manual pollination in Jiangxin Island?" On the road, Li Sanghai raised his questions.

"I'm on Jiangxin Island, it's okay to be idle, always watching the grass there, looking at flowers, it was discovered inadvertently at that time!" Li Yunrui had long thought about the excuse of Li Sanghai.

On Jiangxin Island, in addition to solving technical problems with artisans, or on the rafting river, Li Yunrui was idle and bored, and he could only squat on the ground to see flowers and plants.

He also wants to watch mobile phones and play a computer, but there is no such condition!

"The young master can look at it casually, it is really amazing ..." Li Sanghai heard Li Yunrui's ghost words, and he was suddenly shocked.

"Sang Hai, that is not a simple look, but a scientific research method. Bold assumptions, carefully verify, and then promote the results you want through careful observation, meticulous analysis, and layer by layer!"

Li Yunrui continued to flicker Li Sanghai. As long as he said the usual things and said, others would convince others.

It's bold, careful, observation, and analysis.

If the head is the way, Li Sanghai really believes in Li Yunrui's ghost.

Of course, this is not a ghost. After all, the scientific research of later generations adopts this theory.

With potatoes into the kitchen, Li Yunrui was worried. There were eight potatoes in total, more than a pound, a family, one person, one person was not enough!

Li Yunrui, who was unwilling, ran to the back garden again, and planned two potatoes to be satisfied. He took a few more peppers.

A plate of green pepper potato shreds, a plate of potato stewed beef, and a pot of potato soup soup, which has received praise from everyone up and down of the Li family.

"Brother, can you eat tomorrow?" Li Wanqing looked at the rice bowl in his hand and looked at Li Yunrui with his eyes and asked.

"Yes! Why not?" Li Yunrui squeezed Li Wanqing's face and said, "As long as Wan Qing wants to eat, my brother will do it for you, let's change the figure!"

Li Jinglong listened to Li Yunrui's words, his face was black, and he looked at Li Yunrui with a tiger. He cough twice.

"Old beans, don't distress! Without potatoes, people have come here for thousands of years. Let them wait for two years, it doesn't matter ..." Li Yunrui certainly understands Li Jinglong's meaning, but in his concept, Daming's new new’s new’s new’s

Grain species, Guan Lao Tzu Bird? Let me raise my sister first!

Besides, Daming wants to promote new grains, which is not bad for these three or five hundred pounds of potatoes ...

After listening to Li Yunrui's words, Li Jinglong had some chest tightness. Last night, the two also discussed all night, how to use potatoes to keep the Li family's title, Li Yunrui turned his face to forget.

"At most I build a vegetable greenhouse, in winter, plant another season of potatoes, will not delay your major events! I promise!" Then, Li Yunrui made a gesture that he vowed.

"What is the vegetable greenhouse? Good grandson!" Wu's listening to Li Yunrui said that he wanted to grow potatoes in winter, and he didn't understand.

"Grandmother, the vegetable greenhouse is to cover a house with glass. The temperature inside can be planted in the four seasons, and you can plant vegetables in it!" Li Yunrui said with a smile.

"Well ~~" After listening to the people on the table, he took a bite of air.

Things like glass, people in Nanjing now queue up to make an appointment every day, do not necessarily grab it. Li Yunrui actually wants to use it to plant crops ...

"Yun Rui, this greenhouse has a lot of money?" Sanji Cheng said.

"Yes, Sanxiang! If the market price comes, the cost of one acre of land will take about one thousand silver!" Li Yunrui had been calculated in private, because when it came, there was no green leaf dish to eat.

For Li Yunrui very injured, the first time he made glass, he began to calculate the matter of the shed.

Li Yunrui does not intend to make a warm shed with glass, but does the mode of brick wall and glass. He calculates a acre of land and requires a glass of 600 square meters, which is about 3,000 yuan.

"One thousand two acres ..." Cheng's listening to this number, some trembling! Li Yunrui is not planting land, this is to take money and drift water.

"Yun Rui, are you crazy? How many dishes do you grow to make it back?" Yuan's also didn't understand.

"Mother, I am talking about the market price, the glass was made by our own ..." Li Yunrui laughed bitterly and said, "One thousand two silvers, and dozens of acres of dozens of acres are more than enough!"

As soon as this remark came out, it made a group of people exclaim -the cost of glass was so low that there were dozens of times of profits!

Even Li Jinglong didn't know this, let alone Wu, Yuan and Cheng's people.

In addition to Li Yunrui, only Li Sanghai knows the cost of glass, and the cost that Li Sanghai knows is the cost of small batches.

Quartz sand, pure alkali and limestone, the only difficulty in it is pure alkali, quartz sand and limestone are natural products. There is a mine in Liuhe County outside Nanjing City.

Go down.

Daming's pure alkali production is very small, and the price is still very high, mainly because of craftsmanship. The ancients made pure alkali, using plant ash, dried straws and dried ash, wrapped it with cloth, and then repeatedly poured with water, and they got it.

Alkaline water. After evaporating the water, I get impure pure alkali. In addition to sodium carbonate, there is a small amount of potassium carbonate.

Who is Li Yunrui? How can a person who has a history of 600 years of historical knowledge use such a low -end method to make pure alkali? He is preparing to copy the Hou's alkali -making method independently invented by China in later generations.

Hou's alkali production method, also called the combined alkali production method, was invented by Academician Hou Debang, the founder of China's modern chemical industry. The implementation process is very simple. Ammonia gas and carbon dioxide are dissolved in water to form ammonium bicarbonate, and ammonium bicarbonate is mixed with salt water.

, you will get ammonium chloride solution and precipitated sodium bicarbonate crystals.

Heating sodium bicarbonate crystals produces sodium carbonate, carbon dioxide, water, and sodium carbonate is soda ash.

Add finely powdered sodium chloride to the remaining ammonium chloride, and pass in ammonia gas to cause the ammonium chloride to crystallize and precipitate separately. After filtering, washing and drying, you can obtain a solid ammonium chloride product.

, can be used to make chemical fertilizers, which is also the origin of the joint alkali production method!

Calculated in this way, the cost of soda ash is extremely low, which also makes the cost of glass very low.

Who would have thought that some worthless stones and sand could be put together to make glass?

"Yun Rui, is there such a high profit from glass?" Li Jinglong asked after being stunned for a long time.

"o(∩_∩)ohaha~" Li Yunrui, who had slipped up, also realized what he said, smiled awkwardly, and said, "so-so, so-so, so-so, it's not very high..."

"Isn't a profit of dozens of times high?" Li Jinglong's hands were trembling.

"Compared to the Haotian Bright Mirror, the profit from glass is nothing!" Li Yunrui touched the back of his head in embarrassment and said, "The Haotian Bright Mirror sold a few days ago only cost ten taels of gold..."
