This trip home, Lu Shixian didn't need to think about it to know that he couldn't be quiet.

Based on his father Lu Jianguo's mouth, it is estimated that everyone in the village knows that he has been recommended by Yenching University.

I am afraid that after going back, social activities will be indispensable.

I'm afraid it will take a lot of time, but there is no way.

Life not only has the moon in the sky, but also the frost in the ground.

People can't be immersed in poetry and distant places forever, daily necessities are also indispensable.

After making mental preparations, Lu Shixian got on the familiar bus No. 808 and prepared to go home.

After more than an hour's drive, he finally arrived at the bus stop in Xingfu Town.

At this time, it was August, and the hot summer season had not yet disappeared, and the long chirping of summer cicadas kept ringing around my ears, which aroused a little irritability.

After three o'clock, the sun began to set.

But Lu Shixian could still feel the scorching heat wave in the air.

He hurried into the only shelter in the shelter.

Quietly, Mimi stretched out her head to take a look at the situation on Xingfu Long Street, and she slowly felt relieved.

"It's okay, no one is there."

So he took out the small schoolbag and put it on his head as a sun hat.

Then he walked quickly to Long Street, which was the only way he had to go home.

Walking in the shade under the eaves, Lu Shixian looked around.

People are still there, but they all sleep in the main room with reclining chairs.

They will not come out to work until the sun sets and the temperature drops.

"A golden opportunity." Lu Shixian stopped hesitating and hurriedly walked forward.

But before he took a few steps, a little black dog suddenly ran out on his right.

The puppy opened its mouth and looked at him warily while sticking out its tongue.

Lu Shixian was also stunned, seeing the puppy looking like he wanted to gank him, he didn't know what to say.

He has lived here for a long time, and he remembers the dogs on Xingfu Street very clearly.

Two rhubarb and one big white.

The three dogs grew up in Happy Town and have never been anywhere else.

Of course, there is nothing surprising about it. The scientific name is Chinese Pastoral Dog, and the common name doesn’t matter.

But he had never seen this dog before, and Lu Shixian's face suddenly became ugly.

"No way, is it really that bad luck?"

Before Lu Shixian could groan, the puppy had already barked.

Hearing this voice, he already understood in his heart that the matter was irreversible.

An old man nearby didn't seem to be wearing reading glasses, so he instantly transformed into a fighting form.

Then I saw the uncle's deep questioning voice resounding from the whole long street.

"Yeah! Where did the little thief come from? Dare to go wild in Xingfu Town?"

"Look at me roaring in front of Dangyang Bridge, drinking the water from the broken bridge and flowing back!"

"Qinglong Yanyue, gods and ghosts cut their worries!"

Heads protruded from each store, and then their eyes all focused on a tiptoeing figure.

Lu Shixian was speechless for a moment, why does this uncle only listen to Peking opera, why is he making such a loud voice.

He slowly took off his schoolbag, revealing an innocent face.

"This looks like a Lu family doll?"

"The one who escorted Yanda?"

"A top student at Yan University?"

So, Lu Shixian accepted greetings from almost all nearby residents.

He accepted n invitations to play at their homes, but Lu Shixian wisely added a series of qualifiers such as "if there is time, no accidents, and next time" and so on.

Finally, he finally escaped from the crowd of onlookers.

When he came out, he almost didn't know his last name.

Fortunately, at least the way home has not been forgotten.

Subconsciously, he quickened his pace and finally returned home before the sun went down.

Taking advantage of the beautiful sunlight, the family began to enjoy dinner outside.

Mother Xia Xiuman scolded Lu Jianguo while eating.

"It's all about your big mouth. Every time you go out, you are here to show off that the baby is going to Yanda."

"This is all the baby's own efforts. Does it have anything to do with you? Have you taught him since he was a child?"

"Now the whole town doesn't know the news. I'm afraid it's because there are a few pigs fed in the pig farm on the right."

Hearing what his mother said, Lu Shixian laughed so hard that he almost spit out his rice.

Comrade Lu Jianguo not only showed no intention of repentance, but was rather complacent.

"A few years ago, the son of Lao Zeng in the town was admitted to Jinling University of Science, so he was very happy."

"Every time I see me, I always talk about his son. It's so easy for me to feel proud now, how can I not say a few words?"

Speaking of this, he became more and more reasonable.

"Besides, why doesn't it have anything to do with me?"

"Can I have him without me?"

Now, as a language teacher, my mother used to talk to my father until he had nothing to say, but I didn't expect it to be the other way around now.

And Lu Shixian also had to praise his reason. From a certain point of view, there is nothing wrong with it, and it is very convincing.

In the evening, after dinner.

The family sat around and chatted for a while.

But after talking for a long time, no one asked him why he came back.

Perhaps Lu Shixian has long been like a kite with a broken string in their hearts, allowing it to fly freely and stop occasionally.

Just rested for the night.

Lu Shixian started his own experimental plan on the second day.

First of all, he needs to design an experiment that is as rigorous as possible.

This process is actually very important. Many people pay too much attention to data processing, so they greatly discount the experimental design.

In fact, the cart has been turned upside down. If there are too many uncontrollable variables in the experiment itself, what is the use of the data obtained through the experiment?

You deceive the truth, and the truth deceives you.

For him, this job is actually very simple.

The results of the experiment are all in his mind, and the experimental process can be obtained by inverting.

Three paddy fields with the same planting and breeding years were selected, and the same high-quality mid-season rice variety Xiangfengyou 180 was planted in them.

Using the same variety of rice, the crayfish were released according to the number of equal differences in the sowing period, which caused the difference in the number of crayfish in the rice-shrimp co-cultivation mode.

Discuss the content of soil reducing substances and its economic benefits under different rice and shrimp co-cultivation models under the condition of different numbers of crayfish.

Three treatments were set up in the experiment: t1, the mixed soil samples of the plow layer were taken according to the five-point sampling method, crushed, and debris such as gravel and rhizomes were removed, and stored in a refrigerator at a suitable temperature.

At t2, different numbers of crayfish were placed in three paddy fields at the same time. (Minimizing the degree of error due to lobster.)

At t3, soil mixture samples from three paddy fields were collected at the same time.

Among them, step t3 is repeated five times under equal time periods.

The economic benefits of rice and shrimp co-culture include the output value of rice, the output value of crayfish, and the costs of rice seeds, fertilizers, and labor.

The output value of rice and crayfish is converted based on the actual output of rice and crayfish, the value of rice and crayfish is calculated based on the average market value of the latest year, and the costs are calculated based on actual use.

Anyway, the general process is such a process. Lu Shixian will never admit the fact that his experiments are very rough due to limited conditions.

Because he really did his best.
