The seeds that follow the space station in China have grown so high

The reporter learned from the Chinese Academy of Sciences on the 29th that on July 24, the experimental sample of the experimental samples and rice seeds that followed the Chinese Space Station's experimental compartment to enter space have been successfully germinated.

The leaves have grown leaves, high-rod rice seedlings have grown to about 30 cm high, and low-rod rice is also 5-6 cm high. The growth state is good. In the future "The experiment of the whole life cycle, and during the experiment, was stored and frozen by astronauts, and finally returned to the ground with the astronauts to analyze.

The growth and development of rice under the condition of micro -gravity

On July 28, experimental units containing experimental samples and rice seeds were installed in the life ecological ecological experiment module installed to the test compartment of the test compartment, and the experiments were launched on July 29.

This space experimental sample Arabia and rice are two models of plants. Arabiastone represents Gemini, long days, and cross flower plants, and many vegetables, such as vegetables, rapeseeds, etc. belong to the family. The rice represents the leaf leaves, short -day, and grasses, and many grain crops, such as wheat and corn, belong to the grace. This project mainly studies the molecular mechanism of the flowering regulation of Arabidone and rice under the micro -gravity conditions of the space.

The rice growth in the space station is good

"Blossom" is the prerequisite for plants to make a new generation of seeds. The seeds of crops are both food and the carrier of breeding the next generation. With the deepening of the development of people's deep space detection, in order to truly solve the problem of food guarantee for human long -term space exploration, it is impossible to rely on carried grain from the earth to meet the long -term space life and work needs of aerospace members. The problem of production of food.

Because the life of the earth cannot survive without protection under the conditions of severe space environment, the production of space crops in the future must be carried out in a completely closed artificial environment, and the planting space and energy supply must be very scarce. Therefore, the crops of space planting must have the requirements of high -yield, high -quality, high production efficiency and low energy consumption.

Under the condition of micro -gravity conditions

The goal of this experiment is to complete the cultivation and research from the whole life cycle from seeds to seeds in space stations to explore the use of spatial environmental factors to control the flowering of plants to maximize the production efficiency of plant production in smaller closed spaces Perhaps the way, at the same time, through the astronauts to collect samples in the rail, freeze back analysis, identify the key hub gene of the spatial micro -gravity regulating plant flowering and verify it, and provide a molecule for the next step to build high -quality high -quality crops that adapt to the space micro -gravity environment. element.
