Return to space!"Selection of Sky" to open a scientific test

On July 5th, the Three Gorges Group Ecological Engineering Center of the Three Gorges Dam on the right bank of the Three Gorges Dam was boiled. The seeds of Fengdu, the unique plant in the Three Gorges Reservoir, were selected for 183 days after carrying the Shenzhou -thirteen manned spacecraft to travel to space. These "species of heaven" immediately launched the scientific test procedures to prepare for the planning and investing in the embrace of the land of the earth this fall.

At nearly 10 am on the same day, Huang Guiyun, deputy director of the Institute of Rare Plant Research Institute of the Yangtze River opened the seeds of low -temperature, low -humidity storage cabinets, took out a packaging bag, containing several sealing small bags inside, with the "number" of plant seeds, the plant seeds, "Given provides" and other words. "After returning to the place on June 11, the seeds in front of Fengdu car have been stored in the storage cabinet."

After the sealing, scientific researchers Hu Meixiang, Zhu Haofei, Member Chen and others were full of expectations, carefully tearing the packaging, spreading the seeds on the intelligent processing analyzer to collect basic data. This is equivalent to "physical examination", analyzing the weight, size, form, and neatness of the seeds, and the neatness of the seeds, etc., also observe the micro form of the microscope, and then perform germination and transplanting on the ground to view these space "passengers" of "passengers" of these spaces "passengers" Vitality, growth, etc. "We are excited and embarrassed. Every seed is precious and cannot be wasted." Huang Guiyun said.

Subsequently, the scientific researchers put the seeds of Fengdu in the germination box and spread it evenly with gardenia. This is a square transparent box with a diameter of more than 10 centimeters with white hair paper. After dripping the ultra -pure water on the germination paper, the germination paper is like the incubation pond. The seeds smaller than the sesame germinated and growed on it. After the scientific researchers seal the germination box, put them in the light cultivation box to wait for the seeds to grow.

Return to the Fengdu car from space to start a scientific test

It is understood that the seeds returning to the ground from space need to be cultivated for several years in order to "advance" to "space seeds". Huang Guiyun said that Fengdu car dormant in summer and grows in autumn and winter. After autumn, the germinated Fengdu car can be planted on a large scale. They will take care of it, strive to cultivate the "space seeds" in front of Fengdu, and be the protection of the rare plant in the Three Gorges Reservoir area and the new method of exploration of ecological restoration in the reservoir area.

In front of the car, also known as the front of the car, wheel grass, etc., two years or perennial herbs. The grass in front of the car is strong, cold and drought -resistant, not strict with the soil, and can grow well on warm, humid, sunrise, and sandy soil.

In front of the Fengdu car, it is a unique amphibious plant in the Three Gorges Reservoir area, known as the "Grand Panda". Fengdu car was named for the first time in Fengdu County, Chongqing City at the beginning of this century. It was an amphibious plant with extremely limited distribution. It was only distributed in Nengdu County, Zhongxian, Banan District, and Jiangjin District, Chongqing City. Four of the Yangtze River Heart Island, which is isolated from each other.

The plants in front of Fengdu car are short and have the size of an adult's palm. The seeds are not conducive to the spread of wind and water. In the natural state, compared to the "close relatives" ordinary car, the leaves in front of Fengdu car are more sensitive to water flooding, and the roots are more tolerant to water flooding and can form a certain protection mechanism. Every June and July, the water in the Yangtze River is flooded, and its leaves are rotten, but after the water retreats, it can still grow through the root system and mature seeds in August and September. In front of Fengdu, the riverside flooding through the spring and summer dormant, and the season of dry and reproduction of the autumn and winter water is very suitable for planting slopes in the beach of the Yangtze River Basin. It is an important plant resource for the great protection of the Yangtze River. As a unique herbal plant in the Three Gorges Reservoir area, this special lifestyle in front of Fengdu car is a test material for studying plants to adapt to special environmental ecology and ecological evolution. The newly released wild plant protection list in 2021 lists it as a national second -level protection wild plant.

Space breeding is aerospace breeding, also known as space -bearing breeding, is to send seeds to space, and use comprehensive environmental factors such as the special micro -gravity and high vacuum of space to induce the new breeding technologies of the seeds of seeds to cultivate new varieties. As the aerospace mutant breeding was in the ascendant, the Yangtze Rare Botanical Research Institute also set its sights on "space seeds". On October 16, 2021, the front seeds they chose to send them with the expectations of the Three Gorges people, and took the Shenzhou 13 manned spacecraft into space. This is also the first space trip to the Three Gorges Reservoir area of ​​rare plant seeds. On April 16, 2022, Shenzhou 13 manned spacecraft returned to the cabin to land successfully. After 183 days of space, the seeds of Fengdu car were also successfully out of the cabin, becoming a veritable "selection of heaven".

According to statistics, in the past 20 years, the Yangtze Rare Plants Research Institute relocated to protect more than 1,300 species of rare resource plants.
