摘　　要：目的在空间植物栽培装置地面样机研制的基础上,完成空间植物栽培装置地面改进样机的研制,使其工作原理更能适应空间微重力环境条件。方法借鉴空间植物栽培装置地面样机的先期研制经验,在技术方案详细论证与设计的基础上,进行部件图纸设计与投厂加工、整机设备安装、调试和试运行等。结果该样机可自动而有效地控制栽培室内的大气环境参数和栽培基质水分含量;温湿度控制、冷凝水收集和植物养分供应等工作原理基本满足空间微重力环境条件下的使用要求。结论本样机设计合理,解决了空间植物栽培的大部分关键技术难题,为下一步研制上天产品和开展空间飞行试验研究奠定了重要基础。Objective To develop an improved prototype making its operating principle adapt to the space microgravity enviroment better, based on the ground-based prototype of a space plant-growing facility. Methods With the experience of the development of a first-generation prototype of the space plant-growing facility and detailed demonstration and design of technique plan, its blueprint design and machining of related components, whole facility installation, debugging and trial operations were done. Results The atmospheric environmental parameters in the growing chamber and water content in the growing media were totally and effectively controlled;the operating principles of temperature and humidity control, collection of cooled water and supply of plant nutrient can meet nearly the requirements of space microgravity environment. Conclusion The entire systematic design of the facility is reasonable and the key techniques relating to plant growing in space are nearly solved, which lays an important foundation for future development of the space plant-growing facility to be tested and applied in space.
