Stock up in space to survive and save civilization in the end of the world

When young, seedlings are very similar to barnyard grass, but are slightly different in subtle ways.

The surface of the leaves of barnyard grass is relatively smooth and hairless, while the leaves of seedlings are linear-lanceolate and feel very rough to the touch.

The leaf veins of the seedlings have five veins, and the midrib forms a ridge, so the plant in her hand must be a seedling.

However, rice prefers a living environment with high temperature and water. The average temperature during the growth and development stage is between 18 degrees and 25 degrees. The average temperature in Beijing in October begins to fall below 18 degrees.

Lin Qian stood in the field in silence for a long time. She looked at the leaves swaying in the wind and thought silently, these seeds are really tenacious.

Some of it leaked out of the cow's mouth and narrowly escaped death.

Some are not fully digested and linger on.

In the end, everything turns out to be bright and clear again.

Now that all the leaves have come out, continue planting.

Lin Qian checked all the seedlings, but some of them had just sprouted and she couldn't be sure whether all the new ones growing in the field were seedlings.

It may also be barnyardgrass that grows on the ground after the cows eat the grass seeds without having time to digest them.

Most of the seedlings were developing well, which made her even more interested.

If the weather is too cold, you can only ask someone to come over and build a small shed to keep the temperature.

The so-called small arch shed is an arched shed about 1.5 meters high and 3 meters wide.

In 58, China was able to produce agricultural polyethylene film on its own. At that time, Beijing began to promote its use in the Northeast region. She also used it in Heilingtun.

Keeping the matter of building a small shed in mind, Lin Qian went to the dry land again with a glimmer of hope. This time, the miracle did not happen, and there was no movement at all on the dry land.

After plowing the dry land with a hoe, Lin Qian went to the seed bank to get two packages of winter wheat seeds.

Winter wheat seeds should also be sun-dried before sowing. This can break seed dormancy and increase the germination rate. It can also kill pathogenic bacteria and insect eggs carried by the seeds and reduce the chance of infestation by diseases and insect pests during the growing period.

Next, she began her pastoral life of leaving early and returning late.

The sky is filled with summer colors, and the leaves of the trees are moving with the sound of autumn.

In late autumn, Lin Qian found someone to build a small or medium-sized shed in the paddy field.

Several students from the Agricultural University came to set up the tent. She was not the only one. Many people from the Suffering Alliance group also set up tents in the experimental field.

On a sunny day, sunlight penetrates through the film, and the temperature is firmly locked by the film. The temperature inside the shed can basically maintain the normal growth temperature of rice.

There is no need to build a shed for winter wheat. Even snow is more beneficial than harmful to the overwintering of winter wheat. It can not only keep warm and supply water, but also kill some diseases and insect pests.

Old farmers often say: "Three layers of wheat cover will help you sleep with steamed buns next year." This means that if there are three consecutive good snowfalls in winter, there will be a bumper wheat harvest next year.

However, the growth cycle of winter wheat is twice that of rice. Winter wheat sown in October cannot be harvested until May of the following year.

If everything goes well and the thermal insulation effect is in place, the rice harvest period in the paddy fields will be around early January.

Recently, the first dividends from the energy bars have been received, and as expected, they are selling well in foreign markets.

After Lin Qian got the money, she immediately applied to Dean Qin to build a separate laboratory.

All the equipment, instruments, reagents, etc. are paid from her, and the school provides venue and purchase support.

Because there are some things that individuals cannot buy if they want to.

Dean Qin took her application and said that he would negotiate with other school leaders. Lin Qian felt that this could definitely be done, because Dean Qin also had another identity - the school party committee secretary.

Two months later, everything in the laboratory was ready, and Lin Qian quietly hung up a sign saying it was a hybrid rice research laboratory.

The research room is not large, only 35 square meters, which is convenient for her to verify the experimental results of some experts in the literature on weekends.

After the laboratory was put in place, half of the dividend was lost at once, and disposable consumables had to be purchased in the future.

How else should the person in charge of the laboratory be called a boss in the future, because he needs to provide laboratory research funds and student labor fees.

The current tutors are okay, most of them are pragmatic and honest in style, and they are also very tolerant.

After more than ten years, he is really just the "boss".

The laboratory is a gold-eating beast, so the energy bar cannot be given up.

We must continue to innovate and go to Western markets to cut leeks, no, to meet their health needs.

The wind is cold in the north, and the wind is cold in the south.

Lin Qian was very confused. Let it snow. It would be good for the winter wheat in the dry land.

It won't snow, it will be good for the rice in the paddy fields.

The palms and backs of my hands are really full of flesh.

In early December, the snow was still falling, and the small sheds in the paddy fields had been covered with a second layer of film.

The temperature dropped even lower after it snowed. Lin Qian followed Ku Zhuqun's method and started adding carbon pots to the greenhouse at night.

The sun is still relatively strong during the day. After the sunlight is reflected and absorbed by the shed film, a large amount of heat energy will accumulate in the shed, causing the ground to heat up and the soil to heat up.

Burning charcoal in a shed is also a commonly used method to maintain insulation and increase carbon dioxide content.

An appropriate amount of carbon dioxide will increase plant respiration, thereby promoting plant growth.

During the rice flowering season, Lin Qian discovered a special rice plant during her daily inspection.

She took out a magnifying glass from the small bag she carried with her and observed it for a while, her heart pounding.

After putting down the magnifying glass, I took out tweezers and scissors, cut a few small spikes to check, and a thought suddenly appeared in my mind: It seems that this is a natural female sterile strain!

Lin Qian collected a few small spikes, rushed to the laboratory, and looked at them under a microscope, so that she could better determine whether they were female sterile strains.

After confirming, my mind calmed down.

Is this a variant? She couldn't help but start thinking.

In the process of researching hybrid rice, after the emergence of Pinglao's three-line method, two-line hybrid rice also broke through technical difficulties ten years ago.

The two-line method uses photothermal sterile rice as the basic material.

This kind of photothermosensitive sterile rice is very miraculous. Its fertility changes with the changes of light and temperature to achieve the goal of one line and two purposes.

To put it simply, this kind of rice becomes male sterile under high temperatures in summer. When it is crossed with another kind of rice, the seeds that come out are two-line hybrid rice.

But under the low temperature in autumn, it turns into normal rice and self-pollinates.

Theoretically, female-sterile rice is the most ideal restorer line because it does not produce selfing seeds.

However, female sterile rice is extremely rare in nature, and it is difficult to reproduce on its own. No one has found it so far.

The next day, Lin Qian went to the animal husbandry farm, found the administrator responsible for feeding feed, and asked about the types of feed the cattle eat daily.

She currently has two speculations, one is that the seeds have a genetic mutation, and the other is that temperature changes in the shed lead to the emergence of female sterile plants.

All of these must be verified one by one through experiments. Lin Qian feels that there are many things that can be explored here. If the results are stable, this will be a brand new path.
