[Technology Change Life] Aerospace Breeding: Seeds on the "Blind Box"

【Technology has changed life】

Open -column

Scientific and technological innovation, like leverage the earth's leverage, can always create unexpected miracles.

What is this miracle?

It is the movement of the "Hexia Dream of Hexia" in the field. It is the joy of "The End of the End of the End of the World" in front of the screen.

The land of Shenzhou, technology, has never changed or even created our lives with the ubiquitous power today.

The skills of counting science and technology are not only magnificent and surging in the heavens, but also the moisturizing things between ordinary lanes. Science and technology are the weapons of the country.

Where is technology? She is by your side. This newspaper has launched a column of "Technology Change Life". Talk about these decade, the scientific and technological content deeply embedded in our people's clothing, food, housing, and transportation, and takes you to taste the beautiful little bit of life due to technology.

294.78 billion kg!

At this time, when it comes to the total output of the summer grain announced by the National Bureau of Statistics this year, Zhang Xinyue, a large grain plan in Linyi County, Texas, Shandong, is always beautiful. The wind and rain, coupled with the guidance of agricultural technology experts, is another harvest year!

There are good kinds of food for good food. When we talk about the high -yielding generals of the summer grain wheat, Zhang Xinyue's head said: "These kinds of wheat we grow are particularly temper for the land here. The wheat ears are large and there are many wheat grains. It is held in my hand, and the stalks are thick and strong. In the past few years, I still rely on it to get our local 'wheat grain king'. The seeds are different! "

How about the seeds?

It turned out that "Lu Yuan 502" was a new wheat species raised by my country to rely on aerospace breeding technology. Nowadays, the cumulative promotion area in the north has been nearly 100 million acres. In 2018, it became my country's second largest main push wheat variety. Jin Chancan's wheat ears turned into white flowers, fragrant steamed buns, noodles, and put on the table of our people.

How to breed space? Why go to space for breeding? Liu Luxiang, deputy director of the Institute of Cropology of the Chinese Academy of Agricultural Sciences and chief scientist at the National Aerospace Breeding Project, introduced that aerospace breeding is also called space breeding. The special environmental effects such as micro -gravity and high vacuum make a very small number of genetic mutations in these seeds, and then return to the land. After many generations of scientists, scientists will eventually form a new variety with stable characteristics.

In this "difference", which seed can be hit by the cosmic rays and changing genes is unknown. After the sky, the "head" of the lucky seeds will become higher or shorter, some fruits will significantly become larger or smaller, and some will suddenly increase the "disease resistance" skills. The task of scientific researchers is to screen out the mutant genes we want from these "lucky people" and cultivate new varieties. Therefore, aerospace breeding has also been compared to many people as "blind boxes".

This "blind box" is unpackable -the core demonstration base of the aerospace breeding base in Tongzhou, Beijing shows all kinds of new space seeds: tomatoes that are similar to kiwi, skinny crispy pepper series ... Every spring and summer, the farmers and seed dealers from all over the world follow, and the "space fruit" is quietly coming to you and me.

"Aerospace breeding has accelerated the mutation process of agricultural species and material materials through space mutagne, shorten the selection cycle, and provides us with the sources of agricultural species with independent intellectual property rights." Said Zhao Hui, Secretary -General of the Aerospace Breeding Industry Innovation Alliance.

So, is this "blind box" removed safely?

"Of course safe." Zhao Hui introduced that the evolution of animals and plants benefited from genetic mutation in the natural environment. Although the seeds of plants on the sky have mutated, there is no introduction of exogenous genes. These variants are no different from nature. Researchers have also proved the safety of aerospace breeding through the corresponding quality testing and many years of varieties.

As early as the early 1960s, the United States and Soviet opened the space seeds with tests. It was not until 1987 that the ninth returning satellite in my country sent a group of crops to space for the first time, and it opened the prelude to Chinese aerospace breeding. For more than 30 years, with the continuous progress of my country's aerospace industry and breeding scientific research, China has become the world's only country in the world to continue researching and applied this technology. It is currently at the international leading level.

Today, there are hundreds of types of crops such as astronauts and vegetables in my country.

Ensure national food security, benefit the national economy and people's livelihood, aerospace breeding and honor!

A few months ago, the Shenzhou -thirteen group of Shenzhou 13 in the space on space was successfully returned to the earth. Going home with the three astronauts, there are also seeds from more than 50 breeding units across the country, waiting for them to sow and expect them in the new round. The "questioning" with the core cabin brought a new group of crop seeds.

Tightening Chinese seeds and stabilizing Chinese rice bowls, the power of aerospace is making more people see it.
