After extracting the chickens from a huge chicken farm from the World Book, Shi Hao drifted away again.

He believed that the people of Zhujiacun could do well in raising chickens.

And once chickens are grown, will other meats be far behind?

Now that his mental power has been activated, Shi Hao casually observed the situation of the Kong family in the camp.

The Kong family has not yet had time to build their own residence. Some of them continue to live in Jinyuan, and some have moved directly to the academy.

Why don't they build their own homes?

It’s not that I’m unwilling or unable to build my own residence, it’s just that I’m too busy.

"I estimate that if Blue Star's high school students show half of the diligent study spirit of Kongjiacun, everyone can be admitted to Beiqing." Shi Hao sighed subconsciously after seeing the state of the people of Kongjiacun studying in the academy. road.

The people of Kongjiacun, in the academy, vividly explained what it means to forget about food and sleep.

They get up at six in the morning, study until noon, take a ten-minute break, study from noon to six in the evening, rest for ten minutes, and then study from six-ten to two at night.

The hours are frighteningly long.

Furthermore, the efficiency is extremely high.

During the few days when Shi Hao didn't pay attention, they had already sorted out the things they needed in the camp, and started teaching classes.

What the Kong family in Zhujia Village just said is a good example.

In the golden garden, Kong Yao from Kong Family Village shook his head at the gold, silver and copper.

"You guys are not Gang." Kong Yao discerned carefully.

"Not just? What is that?" Jin Yintong looked at Jin Guang, wanting to get an answer from Jin Guang.

But Jin Guang was also puzzled. He had obviously done what was said in the video, so why was the thing he made not just perfect?

"It's not Gang? What is that?" Jin Guang was also confused, so he asked Kong Yae.

"It's wrought iron." Kong Yae answered openly without hiding anything.

wrought iron?

Jin Guang frantically recalled the difference between pig iron and wrought iron.

But Kong Yao said faster than Jin Guang's brain; "The difference between pig iron, wrought iron and steel is generally in the carbon content."

After Kong Key reminded him, Jin Guang immediately remembered.

"Yes. Yes. Yes. Pig iron generally refers to an iron alloy with a carbon content of to %. It is also called cast iron. In addition to carbon, pig iron also contains silicon, manganese and a small amount of sulfur and phosphorus. It can be cast Not malleable.

Wrought iron refers to relatively pure iron refined from pig iron. The carbon content is less than 0.04%, and it is also called wrought iron and pure iron. Pure iron requires very low levels of impurity elements such as carbon, phosphorus, and sulfur. Its smelting is difficult and its manufacturing cost is much higher than that of pig iron and steel.

Iron with a carbon content between 0.05 and 2 percent is called steel.

So, we made wrought iron by mistake? "

Seeing Jin Guang's triumphant appearance, Jin Yintong all sweated for Jin Guang.

Obviously, Jin Guang went to the academy so long before Kong Yae, but in the end, Jin Guang didn't learn as much as Kong Yae did after just a few days. This is not called a slap in the face. What is a slap in the face?

Kong Yao seemed not to have thought of this, and said, "Wrought iron can be made, both good and bad."

"Is it good? Or is it bad?" Jin Yintong was anxious now.

"Yes, the disadvantage of wrought iron is that it is very soft, has good plasticity, good ductility, is easy to deform, can be drawn into wire, has low strength and hardness, is easy to forge and weld, and has limited uses." Kong Yao replied.

"Is that good?"

"The advantage is that it is mainly used as an electrical material. It has high magnetic permeability and can be used in various iron cores. It is also used as a raw material for high-grade alloy steel. Pure iron is rarely used as a structural material. This is due to its soft texture. The strength is not high. Maybe the Institute of Science and Technology will use it." Kong Yae answered in detail.

This time, Jin Guang and Jin Yintong shut their mouths.

He was completely convinced by Kong Key.

On Kimura's side, the situation is the same.

Kong Lin entered the wooden garden. He was sent by Kong Wenxue forcibly, saying that he wanted to complete the labor quota.

Mu Guan and Mu Zhiwen received him in Muyuan.

Before today, Muguan always felt that the construction of Muyuan was very good, it could not be said to be impeccable, but it had to be unparalleled in the world.

Until Kong Lin, who was in a hurry, entered the wood garden.

"What is this about?" Kong Lin preemptively asked.

Mu Guan:? ? ?

"Have you really studied in the academy?" Kong Lin asked Mu Guan again.

"Sir, what do you mean by this? Is there something wrong with Mu Yuan?" Mu Guan was not convinced anymore and faced Kong Lin directly.

Kong Lin was very stubborn.

"What's the problem? It's a big problem." Kong Lin said unceremoniously.

"Please tell me." Mu Zhiwen asked for advice.

"The site selection of your Muyuan orchard and the environmental treatment technology need to be improved!" Kong Lin said without hesitation: "As taught in the academy, the site selection of the orchard and the cultivation environment will have an important impact on the quality of the output.

See for yourself, since the growth of fruit trees is closely related to nearby environmental conditions, is your placement correct?

In addition, light, air humidity, water quality and soil conditions will all affect the growth of fruit trees.

However, in order to reduce costs and look good, you did not comprehensively consider the above factors when selecting the site for the fruit trees, and did not do a good job of handling the cultivation environment after selecting the site.

See for yourselves, you are placing a great burden on the fruit trees.

Therefore, I say that your study is not good at all. I only learned the form, but not the core.

Everything now is just relying on the gift of the land under his feet.What if one day the gift of land disappears? "

What Kong Lin said left Mu Guan speechless.

He did it for the sake of good looks, convenience, and smoothness, but he did not consider the impact of the above conditions on the growth of fruit trees.

Usually, Muyuan relied on the gift of the land under his feet, so he didn't realize it yet.

Now when Kong Lin said it, Mu Guan and Mu Zhiwen felt burning pain on their faces.

"Then, how should we solve it?" Mu Guan blushed and spoke in a low voice for the fruit tree. .seven

"There are three ways. The first is to abandon the fruit trees here and plant them on a large scale. The second is to transplant the fruit trees here. The third is to bag them." Kong Lin quickly gave the answer.

"Bagging?" Mu Guan didn't expect such an operation.

"Yes, bagging. The Academy video said that the bagging technology for fruit trees has been around for many years. The bagging technology is very mature and has been widely used, especially in fruits such as pears, peaches, and apples. Bagging fruit trees is an important way to improve fruit quality. In this case, you can do it," Kong Lin replied.

"Okay. Okay. Okay." Mu Guan suddenly opened his eyes, and a new world opened before his eyes.

He should not stick to the past, nor should he rely too much on the ground beneath his feet. Human beings can always rely on their own hands and brains.

"You, why are you..." so strong?

Muguan hesitated and wanted to ask Kong Lindao.

"I don't have time to explain it to you in detail. I just want to sum it up in one sentence: Only when you see the problem can you solve it. For the rest, you can study it yourself."

After that, Kong Lin left and continued to study in the academy.
