The current concept of tribe members is simple and crude: the larger ones are better.

If a wheat ear can really have twenty grains of wheat, then the same basket of wheat ears can produce a lot of more steamable food. This principle is very simple.

Since Chen Jian said it was OK, the tribesmen certainly believed it.

However, some people have different ideas.

Even though the stories and myths told by Chen Jian have been subtly instilling in the truth that talent is the spirit of all things, some people still feel that there is something they don’t know that is controlling everything.

Just like a person has two legs and a pig has four legs. It blooms when it is hot and witheres when it is cold... All of this is taken for granted, and this is something that God has already destined to.

But now Chen Jian said that one day he would turn the original ten grains of wheat into twenty grains. These people felt a little scary. They didn't understand what they were afraid of and could not express it in words.

Perhaps to use a more fantasy statement, to use a statement that the tribe members cannot sum up, it means that mortals have entered the realm of God and disrupted the order set by God.

Although Chen Jian was so proud, he also knew that breeding was an extremely long process and didn’t know how long it would take to succeed.

For example, wheat, primitive wheat is just an ordinary diploid plant, and like humans, chromosomes are paired.

To put it simply and inappropriately, it is like single eyelid double eyelids, A and a paired with it, meiosis when giving birth, sperm cells and egg cells separate the Aa pair and then combine it with cells of the opposite sex.

The wheat Chen Jian ate in his previous life was actually hexaploid. In layman's terms, the gene pairs in his body were A1, A2, A3 plus a1, a2, a3.

The original Aa wheat has fewer seeds, is ridiculously grown, has poor tillering ability and is not high in fruiting rate.

One day, there may be a spring frost, because the cold induced its chromosome to double, and it became A1, A2 and a1, a2, which is tetraploid wheat.

This tetraploid wheat has become thicker and has produced more seeds.

By chance, it may have hybridized with distant relatives such as wild rye and rye. These distant relatives are diploid, and they are tetraploid, so the base pairing is not perfect, forming triploid seeds.

Gene pairs of even pairs must be used to breed offspring, because odd pairs cannot fit perfectly after they differentiate into sperm and egg cells.

This triploid plant can germinate, grow, bloom and grow ears, but it is infertile and has no seeds in the ears. It is a bit like a mule born from a horse and a donkey, but it is still a little different.

Originally, this kind of infertile seed cannot have offspring, but the miracle of nature appeared again and acted as a maternity and gynecology hospital.

These originally sterile seeds may have experienced another spring frost, either roasted by fire or smoked by some poisonous gas. In short, their chromosomes have doubled, from triploid to hexploid.

Nature cured its infertility and gave it more heterologous genes to make it grow stronger and bear more fruits.

Because wheat is hermaphrodisiac, most of the time it is self-pollinated, I don’t know how many generations this natural hybrid was selected for the ancients; and the doubled chromosomes caused by spring frost and autumn cold is even more accidental.

During the planting process, people found that some wheat had larger ears and stronger tillering ability. They did not know that these wheats had been inadvertently transformed by nature.

But people used their experience to preserve these wheat as seeds, breeding them from generation to generation, and finally spreading the entire world.

This may be a process of tens of thousands of years. Chen Jian cannot control the randomness inside, but he can use external forces to accelerate the process of doubling chromosomes.

As for whether the tetraploid or hexaploid produced is highly productive, it requires a long manual choice.

This is not too difficult. The same principle can be used on plants such as strawberries, forcing them to grow larger, and even allowing tetraploid watermelons and diploid watermelons to cross and create seedless watermelons.

It sounds very high-end technology, but it is very simple.

Winemaking, pottery making, and distilled liquor. There are three techniques that can be done manually. It is nothing more than just cooking more time. This is not the level of high-end technology or high school biology.

If you want to double the chromosomes of a plant, you can use colchicine to induce the seeds or seedlings in colchicine. He doesn’t know the concentration, but he can soak them hundreds of times. You can tell if you record the situation next year.

Colchicine is found in daylily. Eating too much daylily may cause poisoning, and in severe cases, it may cause death. Since people can be poisoned, the content is obviously sufficient.

This poison is very soluble in alcohol and water. It only requires high-definition and soaking of wine, and then concentrates it using the volatile characteristics of alcohol.

Under the current conditions, it is definitely impure, and there will be messy things like pigments inside, but what Chen Jian wants is only a certain concentration of colchicine. It is not an experiment, so there is no need to analyze the pure.

It’s like eating arsenic will die if it is mixed in the soil. If it’s just for the purpose of killing people, why do you have to purify arsenic?

Nowadays, there are also grains, and the yeast chorizo ​​has been improved for several generations, and green mold is gradually decreasing, so there is no problem to use it to make grain wine.

Distilled liquor is nothing more than because the boiling point of alcohol is lower than water, and it will boil when it is over seventy degrees, so alcohol will become steam more likely to fly out than water.

Chen Jian probably knew the principle, and these things were common sense, including everything he had done before. All he had to do was combine this knowledge with the current simple conditions.

He had never seen a wine steamer, but the existing conditions were not impossible to replace it. He pressed the lid of the pot and left a small hole to force the steam to run out of the hole.

Just press a pipe on the small hole, and the pottery pipe does not need to be formed in one go. Now there is fish bladder glue, fish skin, pig skin, and thatch in the village, which can all be used as links to the joints. More than a dozen pottery pipes are glued together, and the longer the better.

Then put some clay pots with holes underneath and penetrate them on top of these pipes. The perforations are blocked with glue and leather. Install cold water in the jar as a condenser to allow the steam in the pipe to cool down to form a liquid to flow out.

Because the boiling point of alcohol is low, the earlier the alcohol comes out, the higher the concentration. This was called the wine cap in rural areas in previous lives, and the first distillation rate can reach forty or fifty degrees.

In order to increase the concentration of wine, the ancients chose to steam three brews, but in fact this is a way to achieve half the result with twice the effort. The so-called three brews are to use wine as water to ferment grain again, but yeasts stop working when the alcohol concentration is high, so the three brews have no egg use. The only useful thing is to steam three brews, and you don’t have to leave this dead end.

If the concentration of the wine distilled for the first time is not enough, steam it again. Only choose the wine leader for experiments. The wine tail is low and can be drunk as wine.

Regardless of cost, there is no need to consider the alcohol recycling problem when extracting colchicine. Even if it can be recycled, he would not dare to drink it.

If everything goes well, and the concentration of colchicine is correct, perfectly hybridizes with rye and only beneficial genes are left, it will take three years to get the first hexploid wheat.

It seems to be a long time, but it is very easy to accept compared to the accidental mutations of tens of thousands of years under natural conditions.

For a future farming nation, nothing is more important than a good breed.

Only when you eat enough can you have more children, and only when you have more children can you occupy the best place, and only when you occupy the best place can you have a greater chance of survival for nations and civilizations.

All this requires is a pair of hands and a head that can apply what you have learned in junior high and high school knowledge, and does not require too profound theories.

Can't calculate the density of the wine without a buoyancy gauge to estimate the concentration of the wine? Make a balance, make a pot of ceramic weight of the same size, weigh the weight of a can of water, and then weigh the weight of a can of wine. Do a division to calculate the density of the wine is the percentage of water, and estimate the concentration.

Can't calculate the concentration of colchicine without a spectrometer? It can be manually divided into hundreds of portions, and the concentration of each portion decreases by one thousandth. Soak the seeds or seedlings separately. Spend an extra year to observe which tetraploids are and which grow thick and deform, and choose the appropriate concentration.

There is no reflux tube to recycle cooling water? Relying on people to keep pouring cold water into it with the clay pot, it is nothing more than a few more people, and it does not require too much, nor is it prepared for mass production. As for the inability to recycle alcohol, it is even simpler. If you don’t want it, it’s just that, regardless of the cost.

When brewing and fermenting wine, don’t know whether the fermented substance is acidic or alkaline? When soaking the kebab, it turns blue, and it becomes alkaline. Just add some steamed vinegar at high temperature. Under acidic conditions, yeasts are more suitable to convert sugar into alcohol.

All the problems can be solved little by little. The fourteen tribes exchanged two or three thousand kilograms of grain, which was enough for him to struggle. If these grains were eaten, they would only be the meal for the tribe members for ten days.

The local method is sometimes effective. He habitually outlines all possible problems on the bark, estimates the possibility of solving it, and thinks that this plan is feasible.

So after dinner, he and his tribe members asked for a few days off.

Now that his mental and physical strength are not completely divided, he positioned himself as a "cadre who is not a job". Now he must do a lot of work, and everything he does now lays a good foundation.

Just like studying in previous lives, why do you have to study so much hardship? Why can’t you play happily? Why don’t you learn happily by studying abroad?

Because of playing happily for a few years, it may be a lifetime of unhappiness. Those children who study happily are squatting in public schools, while those who have been struggling in private schools until midnight run to the Ivy League, continuing to fool more people to study happily.

It is still in its infancy. Even if you want to be arrogant and extravagant, you will not have that chance. If you leave your tribe, you will starve to death. But if your tribe members leave him, you will still live the same way, and you will only make a little slower progress.

After he made the suggestion, the tribesmen happily agreed, and the men claimed that they would finish the floor he should have hoe, which was trust.

Women can do the work of steaming wine; women can spun the hemp immediately; women can only do it if they have children in a few months.

Chen Jian suddenly felt a little sad. His role positioning for a long time... would be the director of the village women's federation.

PS: Explain the title problem. The elm seed is the seed of the elm tree. The name "Yuzi" is only after you have money, but the seeds of the elm tree do not appear after you have money. I have already said that the synonym of "front teeth" appears after you have a door, but it does not mean that humans will grow front teeth after you have a door. There are also names such as uncles and grandmothers. My hometown Guan's aunt calls it a concubine, and Aunt Guan calls it an empress (three tones). This is the same principle. As long as your mother has brothers, there will be uncles, instead of saying that you can have brothers with the uncle.

Well, Blackham, Blackhand; Smith, Blacksmith; Fisher, Fisherman; Taylor, Tailor.

That's it. Thank you for your support.
