Chapter 1437

Although he had experience in delivering babies, it was his first time giving birth. The closer it was to the day of giving birth, the more nervous Yan Xiaosi became.

"It's okay, for the sake of the child, I will be careful."

"Junior Sister, don't mess around, listen to Brother Long and give the water bottle to Brother Long."

Even Chunyu Hanfeng turned to Long Yu, although Yan Xiaosi felt that the two men were making a fuss, but under the serious eyes of the two men, Yan Xiaosi had no choice but to hand over the water bottle to Long Yu.

Long Yu took the kettle and went out to the bathroom on the third floor to get water, and quickly returned.

Afraid that Yan Xiaosi would spill water on the ground and accidentally step on the water stains on the ground and wrestle, Long Yu pondered for a while before handing over the water bottle to Yan Xiaosi.

"Girl, tell me what to do, and I will be in charge of the operation."

Hearing that the man's tone was unquestionable, Yan Xiaosi pointed helplessly at a glass on the table in front of him.

"Pour water into this cup, half a cup is enough, then put the soil we brought back from Gaojia Village into the water cup, and stir with that glazed stick to dissolve the soil in the water."

Long Yu did as he was told.

After the soil was fully dissolved in the water, Yan Xiaosi picked up the PH test paper on the table and handed it to Long Yu.

"This is called litmus paper. It can test the acidity and alkalinity of the soil. Ayu, use the glass dropper on the table to suck some muddy water out of the cup, and drop the muddy water on the litmus paper. After a quarter of an hour, we will You can know why the grain production in Yufeng County is low."

Long Yu took the litmus paper from Yan Xiaosi, scanned the table, found the dropper Yan Xiaosi said, and then did as Yan Xiaosi said.

A quarter of an hour later, the two big men discovered that the originally blue litmus paper had turned red.

Both Long Yu and Chunyu Hanfeng stared at the red litmus paper in amazement.

Chunyu Hanfeng said: "Could it be that the muddy water in Yufeng County has the effect of dyeing? It's a good idea. If the food can't be grown in the future, let the people here open dyeing workshops."

"Don't interrupt, listen to what the girl has to say."

The people in Yufeng County were starving to death, and Chunyu Hanfeng even joked about it, but Long Yu ruthlessly teased him.

Chunyu Hanfeng also wanted to know the real reason why the blue litmus paper turned red, so he closed his mouth and watched Yan Xiaosi without replying.

Yan Xiaosi said: "The litmus test paper is soaked in a special liquid medicine. This kind of test paper has two colors, one is red and the other is blue. The red litmus test paper will be damaged when it encounters a strong alkaline liquid. It turns blue, and it will not change color when it encounters a strong acidic liquid. We are using blue litmus paper now, and now the test paper we are using has turned orange red, which proves that the The soil is acidic, and it is also strongly acidic, and only a small amount of crops can grow in such soil, so the villagers in Gaojia Village will not grow well.”

Yan Xiaosi's words made Long Yu frown.

"The grain yield in Yufeng County is low. Could it be that the soil in Yufeng County is acidic?"

Yan Xiaosi nodded slightly.

"Very likely. Didn't I just say that there was a large-scale forest fire in Yufeng County a few years ago? During a forest fire, the vegetation is not completely burned, and a large amount of carbon monoxide, carbon dioxide and sulfur dioxide gases will be produced, of which carbon dioxide and sulfur dioxide gases are Dissolved in water, these two gases dissolve in rainwater to form acid rain. Acid rain has eroded the soil in Yufeng County for a long time. Over time, the soil in Yufeng County has become acidic soil, and the plant ash left by forest fires is alkaline. Naturally, the original alkaline plant ash can neutralize the acidity of acid rain, and can maintain the pH level of the soil suitable for the growth of various crops. Unfortunately, when Tang Jian took office as a new official, he was eager for quick success and quick profit and ordered people to remove most of the plant ash. The little bit of plant ash left can't neutralize the acid rain at all."

After Yan Xiaosi finished speaking, Long Yu and Chunyu Hanfeng were confused, but the low grain production in Yufeng County was caused by the forest fire and Tang Jian, so they understood.

Chunyu Hanfeng said: "Tang Jian's greasy pig is really harmful."

"Sooner or later that greasy pig will have to be dealt with."

A killing intent flashed in Long Yu's eyes.

Chunyu Hanfeng said: "I thought that greasy fat pig gave the girl to eat vegetables and radishes, you are not angry."

Tang Jian was treating Yan Xiaosi harshly, how could Long Yu not be angry, it was just because Chunyu Hanfeng was taking over his status now, he was not good at attacking Tang Jian as a staff member of the Zhan Palace.

"Are you misunderstanding me?"

"Hahaha."

Chunyu Hanfeng laughed three times amused by Long Yu's words.

"You must retaliate, you are narrow-minded, you deserve to be Brother Long."

Long Yudao: "Brother Chunyu praised you absurdly. When you say that you will be punished, you are narrow-minded. We are not the same."

"Stop discussing Tang Jian, both of you. The most urgent thing now is to go to a few more villages and collect more soil samples for inspection. After all, the soil in the entire Yufeng County is acidic. This is just the guess of the three of us."

"Ah."

Long Yu and Chunyu Hanfeng nodded in agreement with Yan Xiaosi's words.

"Girl, it has been confirmed that the soil in Yufeng County is acidic. What should I do next? Is there a solution?"

How to improve the soil and solve the problem of low grain production in Yufeng County is currently causing Long Yu the most headache.

Yan Xiaosi thought for a while and said, "Alkaline can neutralize acidity. Lime water is alkaline. You can use a large amount of lime water to irrigate the fields in Yufeng County. After continuous irrigation for a period of time, the soil in Yufeng County should be able to recover. improved."

Long Yu said: "The lime water is obtained by dissolving lime powder in water?"

"Yes."

Seeing Yan Xiaosi nodding, Long Yu frowned even deeper.

Yan Xiaosi knew what he was depressed about.

In this world, lime powder can only be obtained by calcining natural limestone. However, natural limestone is limited. If the soil in Yufeng County is acidic, how much lime is needed to improve the soil in Yufeng County? Powder.

Chunyu Hanfeng said: "Limestone, that kind of white stone?"

Long Yu picked him up.

"Brother Chunyu's knowledge has increased. He has lived in my Great Chu Dynasty for less than a year, and he knows Limestone."

Things like limestone are extremely rare in Rongdi grasslands and deserts. The reason why Chunyu Hanfeng knew about limestone was because he and Tantaiyi once went to Siguniang Mountain to dig saltpeter and refine black powder by accident. Tan Taiyi told him that the snow-white stone is called limestone, and after being calcined with fire, lime powder can be obtained, which can be used to build houses.

"I am literary and martial arts, and I have read a lot of books. Naturally, I have extraordinary insights."
