空间微重力下植物栽培水分养分控制研究

Investigation on Water and Nutrition Control of Plant Growth Under Microgravity in Space

通过"天宫2号"空间实验室搭载的空间植物栽培装置,研究了微重力下植物栽培水分养分控制技术.针对空间微重力特点,设计了植物栽培水分养分传导结构,并验证了其可行性和合理性.生菜在空间实验室微重力环境下的顺利萌发、生长发育,证明了水分养分传导结构的合理性和可行性,为后续开展更大规模的空间植物栽培奠定了基础.通过实验,了解了空间微重力下水分养分的传导和分布规律,为研究空间植物栽培水分养分供应方法和测试方法提供了依据.

With the help of the space plant growth facility in Chinese Spacelab Tiangong 2, the water and nutrition control technology for plant growth under microgravity environment is investigated. Considering the microgravity environment, a special water and nutrition conduction structure is designed and its feasibility and rationality are proved by the successful germination and growth of lettuce. This test has laid a foundation of larger-scale space plant growth and helped to understand the laws of water and nutrition conduction and distribution under microgravity. This investigation provides a basis for the research on water and nutrition supply and measurement methods in space.
