Under the leadership of the First Emperor, Zhao Si had his first friendly exchanges with farmers of this era.
"Since you can increase the yield of grain through various methods such as artificial irrigation, pest control, fertilization, etc., have you ever thought that you can actually increase the yield of grain seeds through artificial means?" Zhao Si smiled and started talking.
"When people breed children, most of the children will look similar to their parents. Some diseases will be inherited by the children. You must have heard of it." Zhao Si said with a smile.
Tian Qi nodded and said, "I heard something."
It's a genetic disease.
"Yes, these things that are similar to parents are inherited. For example, if a person's father has single eyelids and the mother has single eyelids, then there is a high probability that a child with double eyelids will not be born." Zhao Si smiled. one time.
"I call double eyelids a dominant gene, and single eyelids a recessive gene." Zhao Si wrote the words "manifest and recessive" on the ground.
Double eyelids and double eyelids, double eyelids and single eyelids, single eyelids and single eyelids.
The visible and hidden are arranged and combined together, and finally the possible eyelid performance results of breeding are obtained.
"So, according to this arrangement, double eyelids and double eyelids may also give birth to children with single eyelids, but single eyelids and single eyelids cannot give birth to children with double eyelids." Tian Qi thought thoughtfully.
"But why is it both hidden and revealed?" Tian Qi asked again.
"And..." Tian Qi frowned a little.
"I have seen two children with single eyelids who were born with double eyelids. This is not impossible." Tian Qi said seriously.
"Hmm...where did we meet again?" Zhao Si, who was still talking about heredity, felt like he was in trouble. When Tian Qi opened his mouth, he smelled the smell of melon and couldn't help but want to eat melon.
~~
Unfortunately, Tian Qi was very tight-lipped and had no intention of leaking other people's private information. Zhao Sigua didn't take advantage of it, and it took a lot of effort to explain to Tian Qi what a dominant gene was and what a recessive gene was.
"So, you think plants and people are the same." Tian Qi asked.
"Exactly, the breeding of plants does not mean that they are planted on the ground and bear fruit. People need to mate to produce offspring, and the same is true for most plants." Zhao Si smiled and began to teach Tian Qi about the pollination methods of plants.
Self-pollination, cross-pollination…
"Peas are self-pollinated. Compared with cross-pollination, self-pollination is more stable."
Pea is a strictly self-pollinating, cleistopollinating plant, so the offspring obtained in the natural state are all purebreds, and the experimental results of hybridization are reliable.
The most important thing is that the differences between different traits of peas are obvious and easy to distinguish, such as tall stems and short stems, and there is no third height in between.
This is very convenient for experimenters to conduct observation and research, especially in this era of relatively backward scientific research methods.
"You specialize in handling crops. You will know this as soon as you do such an experiment." Zhao Si said.
Tian Qi Wenzhi said solemnly: "I only heard that people reproduce through union, but I never thought that the same is true among plants. There are also male and female. Today, I have benefited a lot!"
After Tian Qi stood up and held the disciple's gift as a sign of gratitude, Zhao Si quickly declined: "You are a world-famous scholar, but I just happen to be close to His Majesty, so I cannot accept this great gift!"
The little old man Tian Qi did not accept Zhao Si's refusal, but completed the ceremony seriously.
"There is no distinction between status in the farm family, and there is no difference between everyone. If you can teach me knowledge that I don't know, you are naturally my teacher." Tian Qi bowed stubbornly, then squatted down and leaned over to ask.
"Then if according to this theory, the high-yielding grains that were born before were also processed in this way?"
Zhao Si nodded, of course he couldn't say it was his golden finger.
Tian Qi understood and didn't ask any more questions.
Even if he asked Zhao Si, he would probably not be able to explain such a cultivation method involving national origin.
Although Zhao Si had already explained the reason for the high grain yield, Tian Qi still felt it was strange instinctively. However, because of the new knowledge, Tian Qi did not think too much and just wanted to re-verify Zhao Si's theory. Pea experiment.
Zhao Si gave Tian Xin a handful of pea seeds by the way. These things finally had a reasonable explanation, and he would not be too ostentatious in the future.
Human beings, if they can believe in science, they will definitely not believe in metaphysics when they are idle.
In the days that followed, Jia Zhu continued to move forward...
Tian Xin started experimenting with peas.
From time to time, I asked Zhao Si privately about some doubts about the experiment. Zhao Si explained everything he knew one by one without hiding anything. If he didn't know anything, he recorded it with Tian Xin.
Zhang Cang and Chen Ping also followed the steps of Chen Sheng and Wu Guang and joined Li Si to help Li Si handle paperwork.
The central government held team building meetings in private many times to clarify the purpose of uniting around Zhao Si.
The First Emperor's journey no longer encountered any accidents. The journey was very smooth and there were no major setbacks.
Every time he passed a place, Dunruo would send people under the Black Ice Platform to spy on the local ecological conditions.
There are more and more names on the relocation order. These are all objects that Heibingtai has inspected and deemed necessary to relocate.
After traveling for a long time, we finally arrived at Chenliu County...
When Zhao Si is free, he always checks for gaps and fills them in, thinking about other talents that he has forgotten.
Although after Zhang Cang's explanation, Zhao Si was no longer a Menggu man and knew that the moving order was led by Li Si, but everyone had been captured and things had begun, and Zhao Si planned to finish it as much as possible.
As a time traveler, how can I not have the idea of collecting famous people?
While passing by Chenliu, Zhao Si finally remembered an unlucky guy.
Li, a drunkard in Gaoyang, eats it!
Li Shiqi can be regarded as an outstanding figure in the early Han Dynasty...
Unfortunately, he did not catch up with the establishment of the Han Dynasty, and was cooked and killed by the King of Qi.
Today's Great Qin is not yet full of smoke, and Li Shiqi has not made a splash, but is quietly working as a doorman in Gaoyang.
Since he is a member of Daqin's civil service system, things will be much easier to handle, and Zhao Si does not need to arrest people in a big way.
He bluntly wrote a transfer statement in the name of a close servant of the First Emperor and submitted it to the county guard of Chenliu County, asking the county guard to assist him in transferring Chenliu County officials to follow him.
The governor of Chenliu County was confused when he received the document.
Who is Zhao Si?
He was a close official of the First Emperor and the most favored by the First Emperor.
It's hard to say whether we can build a good relationship with this kind of person, but we must not offend him. The tragedy that happened in Dong County is still vivid in our mind.
County Sheriff Chenliu did not dare to neglect. Although he did not know why Zhao Si asked him to be transferred to a small doorman, he immediately implemented it.
He didn't want to get close to Zhao Si, but wanted to get rid of Zhao Si as soon as possible.
Zhao Si's reputation in the Great Qin court was pretty good, and Zhao Si's letter alone was not asking for a bribe. Naturally, County Sheriff Chenliu had nothing to do with him.
Although he didn't know who Li Shiqi was, Da Qin's civil service system was still very reliable. It didn't take long for County Sheriff Chen Liu to find Li Shiqi.
Li Shiqi, a native of Yongqiu County, is now serving as a doorman in Yongqiu County. County Sheriff Chen Kui naturally delegated the order to Yongqiu County and asked the magistrate of Yongqiu County to cooperate with Zhao Si to complete this small task for Li Shiqi. The transfer of doormen.
"Zhao Si? A close official of the First Emperor?"
At Li Shiqi's home, he looked at the magistrate of Yongqiu County who came to his door. Li Shiqi lay on his side on the bed, drank all the wine in one gulp, and let out a sneer.
