The high -straw rice seedlings have grown to about 30 cm

The reporter learned from the introduction of the manned aerospace engineering space application and space station in Beijing and Shanghai on the 29th. At the introduction of the advanced progress of the training experiment of the space station, the Chinese Space Station asked the Arabia mustard and rice seeds in the China Space Station in the experimental cabin. At present, the growth status is good, and the launch of Arabia and rice will be carried out in space "from seeds to seeds" all life cycle experiments in space.

In July 2022, I asked the Tianjin Experimental Curring to successfully launch and dock with the Tianhe Core Card. On July 28, the experimental unit containing experimental samples and rice seeds was installed from a astronaut to the Tianshi experimental cabin. In the module of life ecology, the experiment was launched on July 29 through the ground program injection instruction.

At present, multiple leaves have grown, and high -straw rice seedlings have grown to about 30 cm, and low -straw rice has grown to 5 to 6 cm high. "Earlier, my country has successfully completed the experiment of Arabidone's full life cycle from seeds to seed '' from seed to seeds. I hope that through this study, the rice 'from seed to seed' whole life cycle under the condition of space micro -gravity in the world The training experiments and the key environmental parameters of rice training are obtained to provide theoretical guidance for the use of rice for spatial grain production. "Said Zheng Huiqiong, a researcher at the Molecular Plant Science Innovation Center of the Chinese Academy of Sciences.

Zheng Huiqiong said that due to the scarcity of planting space and energy supply, the crops planted by space planting must have the characteristics of high -yield, high -quality, high production efficiency, and low energy consumption.

According to reports, in the past 60 years, scientists have conducted a lot of research on space planting and cultivation plants. The current research focus has gradually expanded from the research on the stage of plant seedlings to seed production research. The crops have completed the "from seeds to seeds" experiment in space.

"Flowing is a key link for plant development. Under space conditions, problems such as delayed flowering time, low number of flowers, low seeds, and decreased seed quality are still not overcome." Zheng Huiqiong said that this experiment will explore the use of spatial environmental factors. Control the flowering of plants to maximize the efficiency of plant production in a smaller closed space to provide theoretical basis for further creating crops that adapt to the space environment and development and use of spatial micro -gravity environment resources.
