It was rare for Su He to have some free time, so he took his children to visit the Agricultural Institute of the Academy of Sciences.

The main purpose of his coming here is not to take care of the children.

Su He received a report that important breakthroughs have been made in the breeding of cold-resistant potatoes and cold-resistant corn, two staple foods in alpine regions.

Both crops, cold-resistant potatoes and cold-resistant corn, can be grown near the North Sea and close to the Arctic Circle.

The Chinese nation is a farming nation. If you want to hold a piece of land, the most important condition is that it can be cultivated.

Rice and wheat are more palatable to people, but for these two crops, there has been no breakthrough in the technology for growing them in alpine regions.

Su He learned that breakthroughs had been made in alpine potatoes and alpine corn, and he immediately came to the Institute of Agriculture of the Academy of Sciences to learn about the situation.

He waited in the pavilion with his children and asked the guards to notify relevant personnel.

Su He looked at the large number of crops planted around the pavilion.

He pointed to the wheat growing beside the pond and asked his eldest son Su Shu: "Su Shu, do you know this plant?"

His son Su Shu is likely to be the future emperor.

He doesn't even know about grains, so it's easy for him to say why he shouldn't eat minced meat.

If this happens, it is because Su He, the father, is unqualified and fails to educate his children well.

Su Shu smiled and said: "Father, I know it, it is wheat.

But I don’t know exactly which wheat variety it belongs to.”

The second son Su Lei saw his father asking his eldest brother, and he said anxiously: "Father, I also know this kind of crop.

I also know that the crops in the pond are rice, and corn is grown where we just walked.

These three crops are the main foods that people eat now."

When Su He saw that his sons were doing well, he smiled and said, "Okay, you are all very good."

A young man in his twenties who looked somewhat similar to Su He came next to them holding a large box.

When Su He saw him arriving, he showed a satisfied look.

This is Su Lin, his fifth uncle Su Wuniu's careless playboy son.

After receiving education, young people have now become the backbone of the breeding profession.

He studied under agricultural academician Li Dajiang and was proficient in crop breeding.

Su Lin looked at the frostbite scars on Su Lin's right hand. He had just returned to the capital from the upper reaches of Heilongjiang River.

When Su He saw Su Lin wanting to salute, he quickly stopped him and said, "Xiao Lin, you know the purpose of my coming here, which is to introduce to us the situation of cold-resistant potatoes and cold-resistant corn."

Su Lin also knew the seriousness of the matter, so he opened the big box in his hand.

There are three potatoes bigger than your fist and hundreds of yellow corns.

Su Lin introduced: “Potatoes and sweet potatoes are two crops grown with tubers and roots.

They have one common characteristic, which is breed degeneration.

We still don’t understand why the varieties of these two crops have deteriorated.

But after a long period of practice, the new teeth that had just grown in were treated with sterilizing agents.

After further cultivation, the degeneration of some potatoes and sweet potatoes disappeared and they grew stronger and larger.

After several years of cultivation, these improved seeds continue to deteriorate...

Our Institute of Agriculture, Academy of Sciences, has mastered potato and sweet potato breeding technology.

Breeding centers in various provinces are now promoting this breeding technology to maintain the excellent seeds of these two crops."

Su He listened to Su Lin's introduction and knew the specific reason.

In crops such as potatoes and sweet potatoes, which reproduce asexually, viruses infected by the mother plant will be passed on to the offspring.

The yield difference between poisonous seeds and non-toxic crops can be more than ten times higher.

They are infected with plant viruses. With today's microscopes, tiny microorganisms such as viruses cannot be seen.

But scientists have learned about bacteria through microscopes and have explored ways to sterilize plants.

, also effective against some viruses.

Su Lin said sheepishly: "Your Majesty, there is something wrong with me. I am usually a bit talkative.

Now I will officially introduce cold-resistant potatoes and cold-resistant corn. These two crops are carefully cultivated by us.

According to His Majesty's previous instructions, we asked the Mongols for relevant information.

We tested the planting temperature of cold-resistant crops, which is similar to the planting temperature in the North Sea region, ensuring that these two crops have sufficient yields in severe cold areas.

We were divided into multiple teams and tested in different places.

Cold-resistant potatoes and cold-resistant corn grow better in cold areas and can also grow normally in normal temperature areas such as the Central Plains.

We tested it in Qiongzhou Prefecture, where the temperature was relatively humid and hot, so the growth was not good.

We have confirmed that this cold-resistant crop likes cold but not heat."

Su He listened to Su Lin's detailed introduction to cold-resistant crops. He was indeed a bit talkative, and the content was rather verbose.

Suhe is the most productive, and the output of these cold-resistant crops is about 70% that of the Central Plains.

This is already an extremely high yield, which shows that it is completely feasible to engage in agriculture on the prairie.

Especially in the Mobei Mongolian region, there are many sandy lands and it is very dry.

Potatoes and corn, among the staple foods, are extremely drought-resistant.

Su Shu asked curiously: "Uncle Xiaolin, this is amazing, how do you know which kind of corn is cold-resistant?

If I didn't really understand it, I would have thought it appeared in fairy tales."

Su Lin glanced at Emperor Su He, and then he explained: "There is no shortcut in breeding.

It has only one secret.

Cast a wide net and the fittest will survive.

For example, with cold-resistant corn, we brought more than 2,000 varieties of corn that were induced to mutate and hybridize through various means.

Plant them locally on Heilongjiang farms in early spring and late autumn.

Of more than 2,000 varieties, only 37 varieties grow normally and 11 varieties meet the minimum yield requirements.

We use the ancestors of these eleven varieties as male and female parents for cross-breeding.

Repeating this process, continuous breeding, and a little bit of luck, you can select the right variety."

After Su Shu heard this, his eyes widened, looking very curious.

Su He patted his son on the shoulder and said, "You will go to college soon, and then you will know the power of science."

He turned to Su Lin and asked, "Are the first batch of seeds enough?"

Su Lin said in a relaxed tone: "I have bred these two varieties at the Heilongjiang Breeding Center...

At the same time, large-scale trial planting was conducted to confirm that these cold-resistant potatoes and cold-resistant corns can grow normally.

The first crops have been harvested and they are ready for sale as seeds.

There are one ton of potato seeds and three tons of corn seeds. They are all stored in the cellar and will not mold or rot.

However, these seeds have to be supplied to the three northeastern provinces, so only a quarter can be extracted.

Corn is a hybrid variety and cannot be planted again."

When Su He heard that there were so many seeds, he said with satisfaction: "These seeds are enough for early promotion.

You have made great contributions, and I will reward you later.

If this strategy really succeeds, you will be famous in history."

Su He understood clearly, and he took his children to visit the Agricultural Institute of the Academy of Sciences. There were many novel things here, and the children had a lot of fun.

…………………………

Su He was in Qianqing Palace, reading the memorials of Prime Minister Wang Zhongce.

The policy he proposed has been discussed and revised for many times, and this is the final version.

In order to maintain the superficial peace, the robbery team was dispatched on the grassland in the name of horse bandits.

Later, they were canonized in the name of recruitment.

After many revisions, Wang Zhongce no longer selected ordinary people to take on real tasks.

of gangsters.

A good citizen who lives in a bandit's den for too long will turn into a person with serious banditry.

Wang Zhongce chose the method of walking quickly in small steps, conducted experiments in advance, and selected a special group of people-prisoners.

The internal codename of these people in the imperial court is the Prisoner Army.
