After giving the order, ten dark-skinned men came in from outside.
These men were all tanned and shiny by the sun.
The leader was a man about 1.9 meters tall.
He walked in front.
He stepped forward and cupped his fists and said, "Peng Ling pays homage to the Lord of the City."
These people have not yet joined the military ranks, so they are still called Lord Qingcang City.
"The ten of you are all top agricultural leaders and have passed the test of time.
I called you here today because I have something to tell you."
"Lord City Lord, please speak."
"I want you to plant crops this winter."
As soon as these words came out, ten people felt incredible.
Some people even speculated: "Mr.
City Lord, are we not doing a good enough job?
You deliberately made our winter crops unable to survive.
How can we plant them?"
"Yes, I have been farming for more than ten years, and I have never heard of anything suitable for planting in winter."
"Lord City Lord, are you testing us?
I think planting in winter is just a fantasy and impossible to achieve."
Among the ten people, no one is sure to complete it.
After all, the temperature is too low and the seeds cannot germinate.
How can you plant it?
As the leader of these people, Peng Ling has slightly more experience than the other nine.
He said: "Lord City Lord, as long as you can solve the heat source problem, it's not impossible."
Peng Ling thought more than others.
He looked directly at the essence.
Why crops cannot be grown in winter is all because of the temperature.
If the temperature is right, it will not be repaid.
Guo Jiabo read a lot of books and picked up some ancient records at his fingertips.
He said: "According to ancient book records, in the seventh year of Yongchu (AD 113), some people dug pits to use the ground temperature to induce germination and raise seedlings, and some people burned fires to increase the temperature.
We may be able to achieve this through these two methods."
Peng Ling glanced at Guo Jia.
This young man was so knowledgeable.
Because these two problems just solved the problem of temperature, planting would be feasible.
Peng Ling said: "The real problem is before us.
We don't have places with high ground temperatures in Huaxia City.
Even if there are, there are only a handful of them.
The number is pitiful.
If the city lord wants to grow crops, it's not just as simple as one or two acres of land, right?"
There are records, but it doesn’t explain what is required to raise the temperature by burning a fire.”
In fact, there is another problem, that is, vegetable crops that are not exposed to sunlight are directly yellowed, just like the soybean sprouts we eat every day.
Peng Ling raised the difficulties of two problems, each of which is very serious and must be solved before crops can be grown.
Peng Ling added: "It's not that we question the Lord of the City, but that this is quite difficult.
Everything is silent in winter.
It would be good if we can plant it.
First, pests will not appear.

Second, it is a rare commodity.
I believe in this vegetable.
The crops will definitely sell for a good price.”
In ancient times, there were a wide variety of drugs used to prevent and control pests.
Plant-based drugs include Jiacao, Mangcao, etc., animal-based drugs include mirage, fishy water, etc., and mineral-based drugs include salt, sulfur, lime, arsenic, etc.
Methods used include mixing into seed collections, planting with seeds, soaking in water or boiling juice and spraying, lighting smoke, smearing insect holes, etc.
As early as the Spring and Autumn Period and the Warring States Period, the government even had to set up officials to control pests.
Every time when pests are rampant, there will be a spectacular scene of "all the people catching insects".
In the Jiangnan area, ducks are also raised in rice fields to drive away pests.
The ducks eat the pests, and their feces provide nutrients for the rice.
They are truly mutually reinforcing.
If you can grow vegetables and fruits out of season, there will be no pests and a lot of manpower will be saved.
At the same time, it can improve the economy, exchange for more supplies, and provide some fresh food for people's tables.
Qingcang said at this time: "Well, I know all these problems, but there are still ways to solve them."
Now the doubts on everyone's faces became even more intense.
They thought to themselves, what method could solve the problem of temperature?
Since their minds couldn't think of a method at all, how could Qingcang think of a method?
"The solution is in this book" What Qingcang was holding was a glass manufacturing method.
Everyone was confused about what glass was, so Qingcang said: "This is a transparent material.
Xu Dezhi, please bring this thing over."
Xu Dezhi was already in this room at some point.
He was holding a fifty-centimeter transparent object in his hand, which was glass.
Xu Dezhi said: "Commander, this piece of glass is probably the largest glass we can make."
It turns out that Qingcang had been working on applying some modern materials to ancient times, and glass was just one of them.
Since Wu Chaojing mentioned planting vegetables and fruits in winter, he took out the glass.
If you want to grow vegetables and fruits in winter in modern times, you first need to use a greenhouse, and the material used in the greenhouse is plastic film.
However, such high-tech things cannot be produced in the current technological environment, so glass will be used instead.
At present, the production capacity of glass is limited and it is impossible to use it in large quantities.
The greenhouse he imagined was a little different.
In ancient times, labor was valuable unlike in modern times, so he planned to modify the structure of the greenhouse to suit the ancient production environment.
Now everyone was even more puzzled, they were confused by Qing Cang.
"The glass in the hands of the City Lord can be planted."
"You just have to do it my way."
Qingcang drew an arched structure on paper and said: "This arched structure is called a greenhouse.
The upper section is made of glass.
The glass must be firmly connected to each other.
Concrete is poured on both sides to form an arched structure.
During the day, sunlight can When the glass shines into the greenhouse, the temperature inside the greenhouse will rise accordingly.
At night, some grass quilts should be covered to prevent the temperature from getting too low.
I also reserve a stove here.
When the temperature is too low, I can light a fire to raise the temperature inside the greenhouse. temperature.”
He introduced the structure of the greenhouse eloquently, making everyone admire him.
At the same time, they also had some doubts.
Can this thing really work?
Others did not believe it.

Anyone who has followed Qingcang for a long time understands that he has never They always surprise people and never let anyone down.
There is nothing to lose if you give it a try, especially ten people who are doubtful.
"These structural issues will be left to Minister Yang.
Xu Dezhi, you and Minister Yang will provide enough glass.
I want you to complete one hundred acres of land in a short period of time.
It will be regarded as a test field.
And Peng Ling's Agricultural Encyclopedia introduces some methods to increase production.
Take it back and study it carefully.
I hope you can succeed.
"Qingcang is still the leader in doing this, because he brings new technologies.
Everyone.
No idea.
These people didn't know that these two books alone cost him thirty days of life.
After receiving the order, everyone went down to arrange everything.
This matter has been taken care of.
He directly gave Peng Ling the Agricultural Code, which meant very clearly that agriculture might be managed by him.
Judging from the questions he raised, this person is quite thought-provoking.
At the same time, these people were selected from the people.
