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

Dean Qin not only approved Lin Qian's application, but also asked her in detail about her research direction. After hearing her research ideas on "sea rice", he actively encouraged her to do research and even wrote her an email stamped by the college. Letter of introduction with official seal.

In addition, Dean Qin also suggested that before going to the field, she should go to the school's post bar to read "Tian District Diary".

Lin Qian followed her good deeds and turned on the computer when she got back to the dormitory, and went to the school forum to read posts.

The Field Diary is the highlight of the Agricultural University Post Bar. It contains the history of blood and tears of agricultural students serving crops in the fields.

【3.18 In the spring, I planted the seeds of hope. 】

【3.19 The seeds were dug out by little animals from nowhere and eaten! 】

[3.21 Thanks to the teacher’s help, I started making a scarecrow and a mouse trap. The production process is attached below. 】

[3.30 I stood on the ridge of the field, watching the vibrant buds emerge and the swallows flying lightly in the sky. Suddenly, an unknown object fell on my head. It seemed that wearing a straw hat was not just about protecting the sun. 】

[4.2 After pulling weeds for a week, I found that the senior next door was using paraquat. 】

【4.10 Fertilizer, food cannot be swallowed. 】

······

【10.11 Sow a hundred seeds in spring and harvest a handful of grain in autumn. 】

Lin Qian took a notebook and wrote down information that was useful to her. She prepared straw hats, bamboo hats, and working tools to collect, but some of them were in disrepair, so she had to check them carefully.

Pay attention to the timing of weeding and fertilizing, and pay attention to paddy field drainage during heavy rain.

At present, most of the farm areas of Agricultural University are open fields, with relatively few greenhouse areas, and there are still many uncultivated wastelands around it.

Because the area is too large to be fenced off, in the mature autumn, the battle to defend the results becomes a top priority.

Prevent fire and theft from curious villagers and children nearby.

On the 15th day of the Lunar New Year, Lin Qian went to Shang Mingzhu’s house to celebrate the Lantern Festival together.

She brought gifts from Yangcheng to everyone in the Shang family, and also saw two old tricks that Aunt Shang helped find.

After some conversation, Lin Qian felt that the couple were indeed two honest people.

After she explained the concept of wild sea rice, they did not deny it. Instead, they asked for a long time, and the three of them even planned a route to find along the beach together.

From south to north, when you go to villages near the sea, you not only need to look for wild sea rice, but also take a letter of introduction from the Agricultural University to ask the village chief to find someone to keep an eye out for wild rice seeds growing on the tidal flats.

Lin Qian gave the two of them a monthly salary of 4000. In the first year, they were given a bonus of 10 for finding sea rice, 8 in the second year, and 4 in the third year.

She planned to search for it for only three years. If she still couldn't find it after her senior year, she would just wait for Chen Sheng to find it.

After the Lantern Festival, Lin Qian took the batch slip to the seed bank to get hybrid rice and hybrid upland rice seeds, as well as a pack of ordinary rice seeds. Along with the seeds was a thick sheet of farming precautions.

Observing the seeds in her hand, she found that hybrid rice seeds were different from ordinary rice seeds. The tips of the grains were mostly purple, making them easy to identify.

When Yang and Qi Zhe arrive, everything will be in spring.

In late March, Lin Qian chose a sunny day to dry the seeds for four hours, then used light salt water to select seeds to remove diseased and deflated seeds, and then soaked the seeds to raise the seedlings.

She went to see the experimental field. The school's field area has always been managed and supervised by dedicated personnel, and the soil fertility is well maintained.

But it also took her half a day to sort out the experimental paddy field, making it basically flat and free of weeds.

In mid-April, Lin Qian gave Shang Mingzhu a small medicine box and asked her to take it to Africa. In addition to medicines for headaches, fever, colds and runny nose, there are also Chinese medicine pills she prepared.

After returning, she transplanted upland rice seedlings to dry land without stopping, and then transplanted hybrid rice and ordinary rice seedlings to paddy fields.

After the seedlings were planted, Lin Qian was so tired that she sat directly on the ridge of the field.

Farming is really tiring, and the gap between the peaceful pastoral life and reality is not that big.

Then she started commuting between the fields and campus every day.

Every day when dewdrops are still hanging on the seedlings, Lin Qian gets up, puts on a straw hat and rain boots, and rides an electric bike out.

After finishing the work in the fields, I would record the growth of the rice, and then ride back to campus for classes.

The couple who were looking for wild sea rice called her once a week to report the situation. Lin Qian told them not to worry. Whether they can find sea rice depends on God's will.

After the college entrance examination this year, Xu Xiaodong, Wu Zhenmei, Chen Sheng and Guo Li came to Beijing to play together.

Lin Qian picked up her old friend at the train station and took the four of them to Quanjude to eat roast duck.

At the dinner table, we talked about aspirations, except that Xu Xiaodong’s goal was the University of Political Science and Law.

The other three all wanted to go to schools in Hunan Province. As expected, Chen Sheng embarked on the path of scientific research. He planned to go to Hunan Agricultural University to study plantation industry.

Wu Zhenmei's score is not ideal, second degree is enough, and it is most likely a junior college degree. She wants to major in food, open a fried skewers shop in the future, and make her own fried skewers more and more delicious.

Their fried skewers really tasted good, and Lin Qian never got tired of eating them for two years, so she suggested: "In the future, we can make the name of our fried skewers known and open nationwide franchise stores."

Wu Zhenmei scratched her head, "I don't have that ability. I just want to be self-employed in the county."

Lin Qian glanced at Chen Sheng and asked with her eyes: Why don't you confess your love after the college entrance examination?

Chen Sheng shook his head. The more he liked it, the more he was afraid of it. He was afraid that he would not even be a friend.

Guo Li was eating roast duck and interjected: "I worked hard in my senior year of high school just to be on par with Sister Xi. I can also go to a junior college and become a physical education teacher in the future."

Half a month later, Xu Xiaodong excitedly told Lin Qian on the phone that she was the city's top scholar in liberal arts and that the University of Political Science and Law was stable.

Several others were able to go to the schools they wanted to go to.

During the summer vacation of her freshman year, Lin Qian didn't go anywhere and devoted herself to serving her experimental field.

In early August, when the rice enters its flowering period, she spends a long time in the paddy field every day to observe the natural pollination of the rice.

Rice is monoecious and self-pollinating. Each of its flowers has stamens and pistils inside. When the wind blows the seedlings, the anthers on the stamens will fall on the female pollen, combine with the ovules in the female pollen ovary, and develop into embryos. When they grow up, they will become paddy.

Rice is both the fruit and the seed of rice. If in the south, the rice is not harvested after it matures, it will naturally fall to the ground and then sprout and grow new seedlings.

When monoecious plants are planted together, it is easy for inbreeding to occur, resulting in variation and unstable yields.

In previous research on hybrid rice, the problem that has troubled countless scientists is: monoecious plants are like paint and glue, and it is difficult to separate them. How to separate them like a queen mother?

Ping Lao kept searching in Hunan Province, Yun Province, Qiong Province and other places, and finally found several natural male sterile strains.

The pistils of these male-sterile strains are strong, but the stamens are not. Through artificial cross-pollination, a strong stamen is found for the pistil, and the two strong stamens are combined to produce hybrid rice.

In this process, three parties, namely the sterile line (maternal line), the maintainer line and the restorer line, all contributed. Ping Lao summarized it as the "three-line method".

So in simple terms, hybrid rice means: Can’t the stamens of this rice plant work? Great, if we find another strong stamen for the pistil, the hybrid rice will definitely work!

Hybrid rice was indeed very successful. It was high-yielding, cold-tolerant, disease-resistant, and highly adaptable. It played a great strategic role in China's food security at that time, and also wiped away the shadow of famine in this country with a huge population.

Lin Qian did not find any male sterile strains in her rice. They were all ordinary rice.

After the flowering period, rice can be harvested in 30-40 days.

Lin Qian bought a small electric rice cooker and put it in her dormitory. She waited for the rice to mature and took a bite of the rice grown by herself.
