Scholars in the courtyard.

Chapter 152 Experiment Log
Time is like running water, and it has come to May in a blink of an eye.

In early summer, the sun is shining brightly.

People are already wearing cool, white shirts and gray trousers, and work clothes have also become single clothes.

The courtyard once again returned to calm, and the days that should be lived must be lived, and the work that should be done must still be done.

Even if it's a little bit harder than before, I can always live.

Even the Jia family, which was the most noisy in the courtyard, calmed down a lot after receiving the relief from the uncle.

Except for looking at Yang Xiaotao, the eyes are still resentful.

As for the third master, apart from wandering around the middle courtyard from time to time, he can't say a few words, just want to see when the corn is ripe.

Obviously not dead yet.

In fact, Yan Fugui also knew that a place like Yang Xiaotao could harvest a hundred catties of corn. It was not bad for him to come to Qinqian like this, it was purely calculated and he felt uncomfortable.

Of course, Yang Xiaotao didn't pay attention to him. If he wants to get corn, it's just a dream.

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

In the yard below, the corn has grown to the height of a person. At this time, the difference between the tall stems and the short stems can be seen.

The tall ones almost reach the top of the head, while the short ones only reach the chest.

Today Yang Xiaotao specially asked for a day off to look after the corn in the yard in order to select seeds.

For this reason, Yang Xiaotao sold Wangcai on purpose 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 stage of pollination. At the critical moment, Yang Xiaotao dare not take it lightly.

Xiaowei has already made her home in the cornfield and stays there all day in order to choose the most suitable corn for her parents.

Mendel's experimental data flashed through Yang Xiaotao's mind, and Liao remembered the key points and difficulties.

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

Knowing it is one thing, actually doing it is another.

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

The first thing Yang Xiaotao has to do now is to find the best of the two types of corn for subsequent hybridization.

This work is cumbersome for human beings. It not only needs time to choose, but also needs a lot of scientific data to prove it.

But for Xiao Wei, who can control plants and identify the energy contained in plants, it couldn't be easier.

What Yang Xiaotao wanted was the one with the most energy.

When I came to the two ridges of corn in the experiment, there was a circle of burrs on the edge of the slender leaves.

Yang Xiaotao didn't want to go in. In his previous life, he broke corn for the family when he was a child, and when he came down, all the exposed places on his arms and face were scratched with blood, so itchy and uncomfortable that he didn't dare to scratch them.

"Xiaowei, now start to fertilize the four rows of corn outside, and don't let their pollen get 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.

huh huh
Xiao Wei was instructed to fly over the corns, the outermost corns were turning in unison, the pollen from the male flowers fell to the female flowers below, and the fertilization process was completed quickly.

Afterwards, Xiaowei wandered away for a while, and the male flowers that had just been released quickly withered, losing the ability to release pollen.

"Good job!"

Yang Xiaotao looked at the withered male flowers on the corn stalks outside, and praised Xiaowei.

huh huh
Xiaowei ran up and down, very happy.

"Find the one with the most energy in the root!"

Yang Xiaotao pointed to the short-stalked corn and said that the resistance of corn to lodging must have a well-developed root system, so that it is meaningful to hybridize.

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

Xiaowei was in a hurry, stopping in front of a corn from time to time and whistling twice.

Yang Xiaotao didn't care about other things, he lowered his head and drilled in, marking the target corn with a wooden stick.

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

"Find the one with the most energy here."

Yang Xiaotao pointed to the innermost tall stalk corn.

Soon, three more corns were marked.

Yang Xiaotao wrote it down in his notebook.

On Wednesday, May 5, the weather was fine.

Find excellent parents and optimize them.

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 fantasy, so it is better not to write it.

After writing, close the notebook.

"Xiaowei, fertilize the marked corn."

Yang Xiaotao instructs Xiaowei to pollinate the selected corn, and her male flower pollen will enter the female flower flowers, so as to obtain more excellent parents.

Xiaowei finished quickly.

"Others, self-pollinating."

As for the selection of the rest, Yang Xiaotao didn't care, and let Xiaowei handle it by herself.

When everything is over, Xiaowei is ready to perform the next task.
Ripening.

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

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

Tuesday, May 5th, cloudy

When I got home from get off work today, the selected corn had grown cobs. According to Xiaowei's feedback, it only took three days to mature.

Saturday, May 5, with light rain
Harvest the ten mature corns today, put them in the house, and dry them in the sun.

Ten corn cobs, three tall ones are marked as sample A, and seven short ones are marked as sample B.

Monday, May 5, sunny
After going to work during the day and returning home at night, the two ridges of corn used for the experiment had grown, but Xiaowei absorbed the energy in the middle of the night.

The corn stalks withered instantly, looking a little scary.

The seeds I picked from samples A and B were planted overnight.

Then the "cheating" started again.

Tuesday, May 5th, cloudy

After Xiaowei's efforts, at dawn, the corn planted had already broken through the ground.

Fortunately, Uncle Chen's attention was on Wangcai.

Poor Wangcai.

On Sunday, May 5th, the weather was moderately rainy.

Under Xiaowei's full control and sufficient energy supply, sample A and sample B are about the same size as other corns, but they haven't bloomed yet.

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

I don't have to explain it either.

……

Yang Xiaotao closed the notebook, the rain outside the window gradually thinned out, and the smell of soil came from outside 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 ridges of corn into two waves in his notebook.

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

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

Yang Xiaotao thought for a while and started to do it.

Male flowers A1 to A5 pollinate themselves and B1 to B5.

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

After arranging the numbers, Yang Xiaotao didn't end.

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

Corn tall stems are dominant to short stems, numbered D; long stems are dominant to short stems, coded E; large kernels are dominant to small kernels, coded F; not resistant to lodging and resistant to lodging are dominant, coded H .

"Then, the high-stalk corn that is planted now may be homozygous or heterozygous."

Yang Xiaotao wrote down on the paper, there were many permutations and combinations of uppercase and lowercase letters.

"I hope they are all homozygous, so it will be easy to hybridize."

"However, it is troublesome not to resist lodging, and a heterozygote must be used to extract it."

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

In the middle of the night, the rain outside had stopped, and the yard was muddy, especially in the cornfield, where there were puddles of water, bright as a mirror under the moonlight.

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

Yang Xiaotao put down the pen and paper, stretched his waist, 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 is full of energy, gets up early, and after a simple grooming, he is 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 easy.

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

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

Next, is to wait.

When Yang Xiaotao went to work, the family was still handed over to Wangcai as the gatekeeper, Xiaowei took care of him, and Uncle and Aunt Chen took care of him.

Came to the factory, said hello, and started working.

The workload varies from day to day. Sometimes I am too busy, and sometimes I finish a day's work in one morning.

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

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

When he came to the cafeteria at noon, Yang Xiaotao didn't sell any meat dishes. He ordered two potatoes and two steamed buns with two noodles, and then walked to his seat.

The same was true for several people in the same group. Seeing Yang Xiaotao sitting down, he quickly leaned over.

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

"Squeeze, squeeze!"

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

Afterwards, several people stared at Yang Xiaotao's trouser pocket, which was bulging, obviously something big.

Without any hesitation, Yang Xiaotao took out a small bottle from his trousers pocket, palm-sized, cylinder-shaped, with no packaging on the outside, covered by a red iron lid, with a black ox written on the top.

Inside is a dark red paste, with some lumps that can be vaguely seen, and there is a layer of red-orange oily water on the top layer.

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

Yang Xiaotao put the beef sauce on the table, and everyone looked eagerly.

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

Xing Jiaqi almost climbed up, and the corners of his mouth were drooling.

"Beef sauce!"

"Of course, no beef!"

Yang Xiaotao added that he didn't know if it was beef or not, but the packaging said it was fresh beef juice.

However, everyone is more willing to believe that there is no meat in it.

Now as long as it is meat, it is rare, let alone beef?

But these don't matter, looking at the oil in the small bottle, there must be enough oil and water.

It's such a waste of money that a single high-quality man like Yang Xiaotao can do it. If he is replaced by someone else, whoever dares to do this will not be photographed to death by his family.

"Brother Wang is here!"

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

Of course, there is not much meat in it.

"Hurry up and eat!"

"Xiaotao, did you change this bottle again? Save this one for me today. Last week, the eldest got a bottle, and the second child was in a panic again."

"I have to keep this for me."

Yang Xiaotao nodded, "Just take it back when you're done eating!"

There are still many such bottles and cans in the storage space, but it is not convenient to take them out.

"Eat, eat!"

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

The others were not too polite, and stretched out their chopsticks to pull the meat and vegetables mixed with beef sauce into their lunch boxes, and Yang Xiaotao was no exception.

Several people divided the meat and dishes, and took the chopsticks to spread the beef sauce on the steamed buns, and ate them with big mouthfuls.

After a while, someone next to him stretched out chopsticks from behind, Yang Xiaotao didn't put them away either, and a circle of people surrounded the table immediately.
