Time is like flowing water, and it has come to May in a blink of an eye.

In early summer, the sun is shining.

People are already wearing cool clothes, white shirts and gray pants, and overalls have become single clothes.

Calm returned to the courtyard again, the days that should have been lived had to be lived, and the work that should have been done still had to be done.

Even if it's a little sadder than before, it's not always alive.

is the most noisy Jia family in the courtyard, and after receiving relief from the first uncle, it has also stopped a lot.

In addition to looking at Yang Xiaotao's eyes, he was still resentful.

As for the three masters, except for coming to the middle courtyard from time to time, they can't say a few words, just to see when the corn will ripen.

Apparently not dead yet.

In fact, Yan Fugui also knew that it was good for Yang Xiaotao to be able to harvest 100 catties of corn in such a place, but he came to Qinfeng like this, purely because of calculation and trouble, and he felt uncomfortable.

Of course, Yang Xiaotao didn't pay attention to him, and wanted to hunt corn, dreaming.

Yang Xiaotao stood at the door, holding a notebook in his left hand and a ballpoint pen in his right hand.

In the yard below, the corn has grown to the height of a man, and the difference between a tall pole and a short pole can be seen at this time.

The high pole is fast to the top of the head, and the short pole is only to the chest, which is distinct.

Today, Yang Xiaotao deliberately took a day off to take care of the corn in the yard, in order to select seeds.

For this reason, Yang Xiaotao deliberately sold Wangcai and asked him to take Uncle Chen out for a walk.

There was no one in the yard.

At this time, the corn has reached the pollination link, and at the critical moment, Yang Xiaotao does not dare to take it lightly.

Xiaowei has made her home in the cornfield and stays in it all day in order to pick out the most suitable corn for her parents.

Yang Xiaotao's mind flashed Mendel's experimental data, and there were still key points in the key difficulties, which Liao remembered in his heart.

Of course, there is still a long way between practice and truth.

It's one thing to know, it's another to actually do it.

Especially in the initial stage, it is necessary to come step by step and accumulate experience.

The first thing Yang Xiaotao needs to do now is to find the best ones of the two types of corn and use them for subsequent hybridization.

This work is tedious for humans, requiring not only time to choose, but also a large amount of scientific data to prove.

But for Xiaowei, who can manipulate plants and identify the energy contained in plants, it couldn't be simpler.

What Yang Xiaotao wants is the kind with the most energy.

In front of the two rows of corn in the experiment, there was a ring of burrs growing around the edge of the slender leaves.

Yang Xiaotao didn't want to go in, in his previous life, he broke corn for his family when he was a child, and as long as the exposed places on his arms and faces were scratched on his arms, he was scratched with blood marks, and he didn't dare to scratch it when he was itchy and uncomfortable.

"Xiaowei, now start fertilizing the four ridges of corn outside, and don't let their pollen inside."

Yang Xiaotao pointed to the outermost layer of corn, the biggest function of these four ridges is to block the line of sight and provide cover for the experiments inside.

Woohoo

Vicky was instructed to fly over the corn, the outermost layer of corn rotating in unison, and the pollen from the male flower fell on the female flower below, quickly completing the fertilization process.

Then, Xiaowei wandered again, and the male flowers that had just been released quickly withered and lost the ability to release pollen.

"Well done!"

Yang Xiaotao looked at the withered male flowers on the corn stalk outside, and praised Xiaowei for a while.

Woohoo

Xiaowei scurried up and down, very happy.

"Find out what the root has the most energy!"

Yang Xiaotao pointed to the corn with a short stem and said that corn must have a developed root system to resist lodging, so that it has the meaning of hybridization.

Otherwise, it will only be like what Mrs. Yang said, a natural disaster can ruin all the hard work.

Xiaowei was busy, and from time to time she stopped in front of a corn and sighed twice.

Yang Xiaotao didn't care about anything else, lowered his head and got in, and used a wooden stick to mark the target corn.

Soon, Yang Xiaotao recorded in his notebook that a total of seven corns were selected, and the root system had the most energy.

"Find out the most energy out there."

Yang Xiaotao pointed to the innermost high-stalk corn again.

Soon, three more corns were marked.

Yang Xiaotao wrote it down in his notebook.

On Wednesday, May 6th, the weather was fine.

Find excellent parents and make an optimal selection.

A simple line of words, the process contained in it is not simple.

Of course, Yang Xiaotao will not record in detail, as long as the result is achieved, as for the process, it is too mysterious, so it is better not to write it.

When you're done, close the notebook.

"Vicky, fertilize the marked corn."

Yang Xiaotao instructed Xiaowei to pollinate the selected corn, and his male pollen went into the female flower tidbits to obtain more excellent parents.

Xiaowei was done quickly.

"Others, self-pollination."

As for picking the rest, Yang Xiaotao didn't care about it, and let Xiaowei handle it herself.

When everything is over, Xiaowei is ready to carry out the next task,

Ripening.

Ripening of selected corn is an important step in the experiment.

Only by speeding up the time can you get the fastest results.

On Tuesday, May 12, the weather was cloudy

When I got home from work today, the corn I selected had grown into cobs, and according to Xiaowei's feedback, it would be ripe in just three days.

On Saturday, May 16, the weather was light and rainy

Today, the ten ripe corns are harvested, placed in the house, and dried.

Ten corn cobs, three of the high stalks are marked A, and seven low stalks are marked B.

On Monday, May 18, the weather was fine

After going to work during the day and returning home at night, the two rows of corn used for the experiment had already borne fruit, but it was absorbed by Xiaowei in the middle of the night.

The corn stalk withered instantly, and it looked a little scary.

I selected the seeds from samples A and B and planted them overnight.

And then the "cheating" began.

On Tuesday, May 19, the weather was cloudy

After Xiaowei's efforts, by the time dawn, the corn planted had broken through the soil.

Fortunately, Uncle Chen's attention was on Wangcai.

Poor prosperity.

Sunday, May 24, with moderate rain.

After Xiaowei's full control and sufficient energy supply, samples A and B were already the same size as other corns, but they did not bloom.

In the past few days, Uncle Chen also looked at the yard twice, although it was a little strange, but he didn't think much about it.

I don't have to explain.

……

Yang Xiaotao closed the notebook, the rain outside the window was thinning, and the smell of earth came from the window.

Feeling Xiaowei's breath, Yang Xiaotao thought about tomorrow's work.

The new corn has reached the pollination stage, and the next step is the hybridization process.

Yang Xiaotao divided the two rows of corn into two waves in his notebook.

The tall ones are still A-like, numbered A1 to 10.

The short ones are still B, numbered B1 to B10.

Yang Xiaotao thought for a moment and began to do it.

Male flowers A1 to A5, pollinating themselves and B1 to B5.

Male flowers B6 to B10, pollinate themselves and A6 to A10.

After arranging the numbering, Yang Xiaotao did not finish.

I saw Yang Xiaotao take out a piece of paper from the side and start to write and draw.

The high stalk of corn is dominant to the short stalk, and the number is D, the long stalk is dominant to the short stalk, and the number is E, the large grain is dominant to the small stalk, and the number is F, and the lodging resistance is dominant, and the number is H.

"Well, the tall corn that is being planted now may be homozygous or heterozygous."

Yang Xiaotao wrote down on the paper, and wrote a lot of permutations and combinations of uppercase and lowercase letters.

"I hope they're all homozygous, so it's easy to crossbreed."

"However, lodging resistance is a problem, and it has to be extracted with heterozygotes."

Yang Xiaotao calculated various situations, and then listed the corresponding schemes below to facilitate later experiments.

In the middle of the night, the rain outside had stopped, and the yard was muddy, especially in the cornfield, and it was puddle after puddle, bright as a mirror in the moonlight.

Wangcai was lying in the kennel, and Xiaowei was lying on its back.

Yang Xiaotao put down the pen and paper, stretched, looked at the yard habitually, and then went back to bed to sleep.

The next day, the sky was bright, and the air after the rain was very comfortable and empty.

Yang Xiaotao, who was full of energy, got up early, and after a simple freshen-up, he was ready to start work.

Xiaowei was awakened, came to the corn field, and began to pollinate the corn according to Yang Xiaotao's instructions.

The whole process is short, but not simple.

After the pollen enters the corresponding female flowers, the extra male flowers are removed by Xiaowei to avoid "pollution", and then the pollinated corn itself male flowers must also be removed, each of which must be carefully operated, and each item must be carefully operated.

Fortunately, Xiaowei is small and cautious enough, and the time for a meal has been completed.

Next, it's a matter of waiting.

Yang Xiaotao went out to work, and the family was still handed over to Wangcai to take care of, Xiaowei took care of it, and Uncle Chen and Aunt Chen took care of it.

Came to the factory, said hello, and got to work.

The workload varies from day to day, sometimes too busy, sometimes another morning to finish the day's work.

Looking at the amount of tasks at hand, Yang Xiaotao cigarette butts, and then picked some fourth-level workpieces for processing, and handed over the rest to Li Wei and them.

In the morning, the work is completed, if there is no arrangement, it is estimated that the afternoon will be free time.

When he came to the canteen at noon, Yang Xiaotao didn't sell any meat and vegetables, and directly asked for two potatoes and two Erhe noodles steamed buns, and then walked to the seat.

Several people in the same group were also like this, and when they saw Yang Xiaotao sitting down, they hurriedly leaned over.

Che Wenwei looked at Yang Xiaotao expectantly, and so did several people around him.

"Squeeze, squeeze!"

Next to him, Zhou Peng took the lunch box and inserted it between Li Wei and Li Nan, and the three of them sat on a long bench.

Then several people stared at Yang Xiaotao's pants pocket, which was bulging, obviously not small.

Yang Xiaotao did not hesitate, and took out a small bottle from his trouser pocket, palm-sized, cylindrical, with no packaging on the outside, covered with a red iron lid on the top, and a black cow character written on the top.

Inside is a dark red paste, faintly visible in the form of lumps, and there is a layer of red-orange-orange oil on the top layer.

"Wait a minute, Brother Wang hasn't come yet."

Yang Xiaotao put the beef sauce on the table, and everyone was eager.

"Brother Tao, the mushroom sauce was delicious last time, what is it this time?"

Xing Jiaqi was about to climb up, and the corners of her mouth were drooling.

"Beef sauce!"

"Of course, no beef!"

Yang Xiaotao added that as for whether it was beef inside, what was written on the package was beef juice, and he didn't know.

However, the crowd prefers to believe that there is no meat in it.

Now as long as it's meat, it's hard to come by, let alone beef?

But it doesn't matter, looking at the oily in the small bottle, there must be enough oil and water.

It's also a thing that costs oil, that is, a single high-quality man like Yang Xiaotao can do it, and if he is replaced by someone else's family, who dares to be shot to death by his family like this.

"Brother Wang is here!"

Wang Fa came over with a lunch box and put it in the middle, which was full of two meat dishes.

Of course, there is not much meat in it.

"Let's eat!"

"Xiao Tao, did you change this bottle again? I'll keep this for me today, last week the eldest in the family got a bottle, and the second child panicked again. ”

"I'll have to keep this."

Yang Xiaotao nodded, "When you're done eating, you can take it back!" ”

There are a lot of these bottles and cans in the storage space, but it's inconvenient to take them out.

"Eat, eat!"

Yang Xiaotao twisted the bottle, then poured half of the beef sauce into Wang Fa's lunch box, Wang Fa took it and stirred it with chopsticks, and put it in the middle of the table again.

Others were also polite, stretching out their chopsticks to pull the meat steak mixed with beef sauce into their lunch box, and Yang Xiaotao was no exception.

A few people divided the meat dishes, and then took chopsticks to smear the beef sauce on the steamed buns, and ate them in a big gulp.

After a while, someone next to him stretched out his chopsticks from behind, and Yang Xiaotao didn't pick them up, and there was a circle of people around the table.
