微重力环境下植物培养箱设计

Design of Plant Incubator under Microgravity Environment

基于空间微重力下植物的生物学效应及其微重力信号转导研究需要,在微重力条件下培养拟南芥,获得经微重力条件生长的拟南芥样品.在空间实验过程中实时采集、存储和传输植物样品的数字图像,并根据生物样品的生长周期对生物样品进行低温固定和储存,再由返回式卫星带回地面,开展微重力植物生物学效应研究.

For the research of the plant＇s biological effect under microgravity condition and the requirement of microgravity signal transduction,the seeding of Arabidopsis thaliana were cultured under microgravity condition.The plant incubator is mainly composed of cultivate unit,light unit,fixed unit and observational unit.The cultivate unit contains Unitl and Unit2;the fixed unit contains infusion pump,check value and fluid reservoir;and the observation unit is mainly composed of a visible light camera and multispectral camera.Digital images of plant samples were collected,stored and transmitted in real time during the process of space experiments,and the biological samples were fixed and stored during the culture process.The biological effects of plants under microgravity condition will be studied after the retrieved capsule returning to the ground.
