He also had his own considerations in choosing corn as his first experimental product.
Zhang Yu deliberately searched for information some time ago and also consulted the elderly around him to find out what are the differences between today's corn and the corn of later generations?
In what ways can it be improved?
The current corn is an introduced variety and there are no hybrid strains. In addition, because the introduction time was too short, the planting technology has not been fully mastered.
Corn is not properly managed during its growth, which has resulted in the current corn yield per mu generally being more than 200 kilograms, with the highest not exceeding 350 kilograms.
In fact, the yield of corn in this era is similar to that of wheat in fertile fields.
It's just that compared to wheat, corn is less demanding on land and more drought-resistant.
Compared with the yield of 1,500 to 2,000 kilograms per acre of corn in later generations, the current corn production can be regarded as completely different.

And there is still a long way to go before corn can reach the yields of future generations.
Improved seeds, chemical fertilizers, pesticides, etc. are all indispensable.
Even with a golden finger, Zhang Yu could not make the corn yield reach the sky in one fell swoop.
But at least he has seen the corn of later generations and has a general understanding of the development direction of corn.
In what direction should we go and how?
All have specific concepts.
There is no need to be like today's agriculturalists who have no ideas and can only try one by one.
Moreover, he also has a sign-in system and a secret space as a backing. Compared with agriculturalists of this era, he still has many advantages.
The sign-in system can bring him knowledge, and the huge time ratio between the secret space and reality will also bring huge help to his research.
After thinking about this, Zhang Yu worked harder.
Old Mrs. Sun was sitting at the door basking in the sun, happily watching Zhang Yu work.
From time to time, I would give him some pointers.
When Zhang Yu was almost done with his work, he extended his hand to wave him over to take a rest.
Facing Old Mrs. Sun's greeting, Zhang Yu was not polite and sat down on the bench opposite Old Mrs. Sun. He picked up the warm water on the small table that was obviously prepared for him and drank it down in one gulp.
"Wipe your sweat, are you tired?" Mr. Sun looked at Zhang Yu who was sweating profusely, smiled and handed over a towel.
"Thank you, Mrs. Sun. I'm really tired." Zhang Yu took the towel naturally, inserted it casually, and then put the towel on his shoulders.
"You young people have never endured any hardships. I think back then, before I inherited the family business, I had to endure all kinds of hardships in order to pass the test at home."
Having said this, Mrs. Sun raised his head slightly, closed his eyes and recalled those years.
"Forget it, why am I talking about this? You young people don't like to hear this either."
"Mr. Sun, please continue talking, I like to hear this." Zhang Yu's eyes were full of curiosity and his tone was full of expectation. He loved to bask in the sun and listen to the old man telling stories.
"Okay, okay, if you are willing to listen, I will tell you about that time..."
Old Mrs. Sun narrowed his eyes slightly and told Zhang Yu stories from the past.
At that moment, he seemed to have returned to the past.
People in the courtyard looked at the old man and the young man who were immersed in the story, and they all walked more slowly when passing by them.
I don't want to break the harmonious atmosphere of one old and one young.
After enjoying a moment of peace, the two continued to chat.
I don't know why, but Zhang Yu always feels like he can't hide his words when facing Mrs. Sun.
Unconsciously, I told him my idea of changing my two seeds.
Mrs. Sun is very supportive of Zhang Yu's idea. No matter whether it succeeds or not, no matter when it will succeed, there are always people who have to do some things.
As people grow older, they live in the same courtyard and never look up from each other. Regarding Zhang Yu's matter, Mr. Sun saw that something was wrong.
But he sees things through without telling them. Sometimes he will help cover up areas that Zhang Yu didn't notice.
In his opinion, these children in the courtyard are his juniors, and he will try his best to protect them from outside influences.
Of course, what needs to be experienced still needs to be experienced.
Just like he supports Zhang Yu's ideas and lets him work hard and move forward boldly.
Don't be afraid of making mistakes, but be afraid of not having the courage to try and make mistakes.
Old Mrs. Sun told Zhang Yu not to have any psychological burden and to go ahead and do it boldly. If he failed, it would be okay. If he failed, he would fail. If he failed, he, an old guy, would take care of it.
He also gave him a lot of useful ideas and reminded him of some things he hadn't noticed.
Let him truly understand why people say that a family has a treasure, just like an old man.
With Mrs. Sun's guidance, he can avoid many detours.
Moreover, the existence of Mr. Sun also makes some people dare not take any chances with him.
In the end, Mr. Sun asked Zhang Yu to conduct experiments on the piece of land he was assigned.
With his support, no one dared to touch anything on that ground.
Zhang Yu felt warm in his heart after hearing this.
Just when things were quiet here, there was commotion again in the courtyard next door.
Although they were far apart, they couldn't stop the loud voice of the person who started the quarrel.
Zhang Yu could clearly hear what was going on in the courtyard next door without even changing his position?
After hearing the first sentence, Zhang Yu had already guessed what was going on.
The reason for the commotion above the ninth floor and close to the tenth floor is because of vegetable planting.
Speaking of this, there is something to say.
The residents in the yard next door were jealous when they saw that their yard had divided the free land and used it to grow vegetables.
Even if they are noisy, they still want to be divided.
But compared to how harmonious their courtyard was, no one was making any noise.
It was much more lively when the vegetable plot was being divided in the yard next door, because a little trivial matter could cause a long-lasting fuss.
"Why is your family's vegetable plot bigger than mine?"
"My family is so much larger than yours, why should I be given the same amount of land as yours?"
“Why is my land not as fertile as his?”
"Why is my vegetable patch so far away from the watering place?"
"My vegetable patch is so close to his house, what if he picks it for me?"
"Who are you talking about? Who are you talking about?"
"..."
"..."
All in all, it was a blast.
At the end of the quarrel, the elders in their courtyard could no longer control it, so they came forward from the street and said that if the quarrel continued, they would not be separated, and the matter was resolved.
But even so, there was no calm in the courtyard next door, and there would be trouble every now and then.
Everyone feels that they have been short-changed and that their food has been stolen.
As time passed, their quarrel became a movie to everyone in the courtyard.
Instead of thinking about going forward to break up the fight, they would instead guess through the wall, who was quarreling with whom today, why, and when will the quarrel end?
They even made a bet on who would win this quarrel?
